"FIRE GUN"
PRIORITY CLAIM This claim claims the benefit of US provisional application No. 61 / 433,115, filed on January 14, 2011. This claim claims the benefit of US provisional application No. 61 / 524,138, filed on August 16, 2011. Both of these provisional patent applications are hereby incorporated by reference in their entirety.
TECHNICAL FIELD One or more of the modalities generally concern firearms and, more particularly, for example, a firearm configured to provide a quick barrel change and with features that improve its reliability.
BACKGROUND OF THE INVENTION Semi-automatic or fully automatic firearms are well known. Semi-automatic firearms fire a bullet each time the trigger is pulled. Fully automatic firearms continue to fire as long as the trigger is pulled and as long as your ammo has not run out. Fully automatic firearms typically have relatively high firing rates, that is, cyclical rates. For example, the M16 and M4 have a nominal cyclic rate of 700 to 950 rounds per minute.
Because fully automatic firearms are capable of such high cyclical rates, they are prone to a variety of problems. For example, sustained fully automatic firing can result in overheating of the barrel. Barrel overheating is particularly problematic when using high-capacity tanks, such as SureFire's 60-shot and 100-shot tanks. High-capacity tanks allow for longer periods of sustained fire, since fewer changes to the tank are required to make a given number of shots. Less amount of deposit change gives less time for the pipe to cool. Thus, the barrel, as well as other parts of the firearm, can be subjected to greater heat. Often, the ability to continue firing is limited by the barrel overheating. When the barrel of a firearm overheats, the accuracy of the firearm is substantially reduced. Additional overheating of the barrel may result in the firearm malfunctioning. For example, cartridges placed in the chamber in an overheated barrel can detonate prematurely, that is, ignition can occur - uncontrolled, particularly in closed-bolt firearms. If the barrel is overheated enough, it can deform, thereby resulting in a catastrophic failure of the firearm. Even after the barrel has returned to an acceptable operating temperature, the firearm may become unusable. The barrel and / or other components of the firearm may have been permanently damaged. Changing the barrel of a modern firearm such as the MI6 or M4 takes a substantial amount of time and is generally not carried out in the field. When the firearm becomes unusable due to overheating and while the barrel is being changed, a - soldier or police officer cannot fire the firearm and is thus undesirably vulnerable to attack. The inability to fire a firearm can have a disastrous consequence in camp or police battle situations. Failure to shoot has resulted in loss of life in such cases. - Therefore, it is desirable to provide systems and methods to provide quick change of the barrel of a firearm and to otherwise increase the reliability and usefulness of the firearm, for example.

The rear V-block rests and centralizes the diameter of the barrel extension body while the upper 120º of the barrel extension flange fits into a locking groove in that V-block. The perfect fit of the flange and locking groove combined with the pull up of the oscillating wedge on the pipe's cross pin keeps the pipe centered in the V blocks, locks the pipe in the main support and securely blocks any forward and backward movement of the mouth pipe in relation to the main support structure.
For longitudinal thermal expansion, the barrel slides forwards or backwards on the front V-block and the oscillating wedge follows this movement without releasing its wedge force.
For radial thermal expansion, the two upper arms of a Y-shaped fork fit around both sides of the barrel and have a transverse pin attached through them through the top of the barrel. The ends of the cross pin extend beyond the outer sides of the two arms so that the oscillating wedge of the two arms pulls up the two ends of the cross pin.

(317.5147 Kg). As the barrel of approximately 1 "in diameter (6.4516 cm) expands by the heat of the shot, the angled walls of the V-block force the diameter of the barrel downward, whose center moves down about 0.0045 inches (0, 1143 mm) while the base compresses the spring washers by about 0.009 inch (0.2286 mm), increasing the force to approximately 1,200 pounds (544 kg) as the pipe temperature reaches approximately 1,500ºF (816ºC). remains centered without movement of the longitudinal mouth. The lower fork stem is secured via a front handle. To install a barrel, it is lifted and pulled back by its front handle. Guide surfaces bring the barrel extension into alignment with the locking groove and the cross pin in place with the oscillating wedge that fits by pressing on the pin by firmly pulling the barrel up to its V blocks and locking in the groove.To remove a pipe, the lock end of the oscillating wedge barrel is impact down. The same guide surfaces that - direct it to position yaw it out and down on a path that prevents it from colliding or damaging a deposit. This path is also not obstructed by the two-foot gun support.

Modalities of the present invention and its advantages are best understood by referring to the following detailed description. It should be noted - that identical reference numbers are used to identify identical elements illustrated in one or more of the figures.
DETAILED DESCRIPTION OF THE INVENTION An improved firearm, according to one or more modalities, has several different features that improve its operation and use. For example, the barrel of the firearm can be changed quickly in the field according to one modality. The ability to quickly change the barrel improves the firepower provided by the firearm and thus improves its usefulness. That is, the number of shots that can be taken per minute, including time to change the barrel, is substantially increased.
According to one modality, the firearm can be compatible with large-capacity deposits. For example, the firearm can be compatible with deposits of 60 and 100 shots. The firearm can be configured to withstand the heat associated with sustained fully automatic firing. The ability to quickly change the barrel is one aspect of how the firearm can withstand the heat associated with sustained fully automatic firing.
Three different types of firearms are discussed here.
- These three types are a light machine gun, a semi-automatic (civilian) rifle and a rifle / machine gun. The machine gun can fire both semi-automatically and fully automatically and fire only from an open bolt. The semi-automatic rifle is only semi-automatic and can fire from either an open bolt or a closed bolt. The rifle / machine gun can fire both semi-automatically and fully automatically and can fire from either an open bolt or a closed bolt. The rifle / machine gun fires fully automatically only from an open bolt and fires semi-automatically from both an open bolt and a closed bolt.
Each type of firearm can be made in any desired caliber. For example, each type of firearm can be made according to NATO 5.56x45 mm or 6.8x43 mm. Both NATO 5.56x45 mm and 6.8x43 mm can share components. For example, both NATO 5.56x45 mm and 6.8x43 mm can in general share all components, except the - barrel, bolt and deposit, for a given type of firearm.
The semi-automatic rifle and rifle / machine gun can fire semi-automatic from either an open bolt or a closed bolt. In general, firing a closed bolt provides greater accuracy. However, it may be desirable to switch to open bolt firing if many shots are fired in rapid succession, in order to reduce the likelihood of undesirable barrel overheating. As discussed here, changing from open bolt to closed bolt requires an extra step (such as pressing a button on the selector), in a way that is more likely to make the user consider whether a change like this is appropriate or not, since the closed bolt can result in overheating of the pipe, as discussed here. On the semi-automatic rifle and the rifle / machine gun, each shot is fired by a dog. A long-distance, long-distance dog is used — advantageously, as discussed here. As discussed here, the machine gun is not fired by a dog.
The figures | and 2 show an open bolt machine gun 100, according to one embodiment. The machine gun 100 has fully automatic and semi-automatic shooting capability, as selected by 155 a user. Machine gun 100 fires through an open bolt. Machine gun 100 has a tank 101 attached to it. Deposit 101 may be, for example, a deposit of 60 shots or 100 shots such as those sold by SureFire, LLC of Fountain Valley, California.
Figures 3A and 3B show the machine gun 100 with the tank 101 removed, according to an embodiment. The machine gun 100, as well as the semi-automatic rifle 1000 (figure 10A) and the rifle / machine gun 8000 (figure 16A), can be made in any desired caliber. For example, the machine gun 100, as well as the semi-automatic rifle 1000 and the rifle / machine gun 8000 can be made in 5.56 mm or 6.8 mm.
Figures 4A-4F are additional views of machine gun 100, according to one embodiment. Machine gun 100 has a bottom receiver or receiver assembly 102. Receiver assembly 102 can include a cable 107 and a reservoir well 108.
The main support 103 limits the support of the bolt 111, as described herein. A handle means 109 can be slidably arranged between the main support 103 and the receiver assembly 102 in order to facilitate the frame of the machine gun dog 100 by pulling a ferrule support 111 back. A spring guide 112 can be arranged at least partially into the latch support 111 and can define an anti-kickback system, as discussed here.
A barrel assembly 104 can be removably detachable from the machine gun 100, as well as the semi-automatic rifle 1000 (figures 10A-10F) and the rifle / machine gun 8000 (figure 16A), by pressing a locked barrel 113 into the main support 103, as discussed on here. Barrel 105 may have a front cable 106.
A stock 114 can be removably attachable to the receiver assembly 102. The stock 114 can be attached to a pivot on the receiver assembly 102 in such a way that the stock 114 can bend on either side of the receiver assembly 102. The stock 114 can be a heavy-duty stock as shown. Alternatively, the stock 114 may be a light stock or any other type of stock.
As shown in figure 4A, the stock 114 can have at least one overall horizontal groove 126 formed therein. The groove 126 can allow the user to better hold the stock 114 during firing to inhibit undesirable movement of the stock 114, for example, upward movement. For example, when the stock 114 is wrapped or folded along the side of the receiver assembly 102, a user can hold the handle 107 with one hand and can hold the head 127 of the stock 114 with the other — a cool hand like the thumb. user stay in one of the grooves 126 to hold the firearm more securely.

Figure 8 is a perspective view of a trigger locking mechanism 800 for machine gun 100, according to one embodiment. The trigger lock mechanism 800 is shown with a trigger 801 locked or blocked by a trigger lock bar 802. When a dirt cap 803 is opened due to the handle means 109 being pulled back, then an arm 804 formed in the dirt cap 803, partially rotates the trigger lock lever 833 which prevents movement backwards of the trigger lock bar 802, which in turn prevents movement backwards of the trigger 801. Thus, the trigger 801 cannot be pulled and machine gun 100 cannot be fired when handle 109 is being pulled back, for example, when machine gun 100 is being armed. Dirt cap 803 can open approximately 7 ° to allow handle 109 to be pulled back to arm machine gun 100, for example.
Figure 9 is a perspective view of a trigger locking mechanism for machine gun 100 showing trigger 801 not locked, according to one embodiment. When the dirt cap 803 is closed because the handle means 109 is not being pulled back and is in a forward position, then the arm 804 formed in the dirt cap 803 does not turn the trigger lever 833 to prevent backward motion of the trigger lock bar 802, and therefore, the lock bar of trigger 802 does not prevent movement of the trigger 801 to the rear. Thus, trigger 801 - can be pulled and machine gun 100 can be fired.
Figures 10A-10F are several elevation views of a 1000 semi-automatic rifle, according to one embodiment. The 1000 semi-automatic rifle is not capable of self-firing. The 1000 semi-automatic rifle can be fired from either an open bolt or a closed bolt, in the manner selected by a user. Many of the features of the 1000 semi-automatic rifle are substantially the same as the machine gun 100 discussed earlier. For example, barrel 105 can be released from semiautomatic rifle 1000 in the same way as for machine gun 100. Other features of semiautomatic rifle 1000 are different from those of machine gun 100. For example, machine gun 100 fires in succession, it may have a barrel shorter 105, and can have a heavy-duty cable 114, while the semi-automatic rifle 1000 uses a dog 8203 (figure 21B) to fire, can have a longer barrel 1005, and —can have a lightweight collapsible cable 1014. Some of these different features are interchangeable between the semiautomatic rifle 1000 and the machine gun 100. For example, both the stock 114, 1001 and the barrel 105, 1005 can be used on the semiautomatic rifle 1000 and the machine gun 100. Figures 10G-10I show a trigger assembly for fitting 4000, according to a modality.
The trigger trigger assembly 4000 can be mounted outside of the semiautomatic rifle 1000. Once assembled, the trigger trigger assembly 4000 can be snapped into place in the receiver assembly 102, as discussed here.

For example, the tensioner 8083 can provide a preload of approximately 700 lb (318 kg) when the barrel 105 is attached to the main support 103 via the oscillating wedge 8253.
Figures 55A-55D show the main support and the pipe with several cross sections, according to an embodiment. The pipe 105 is shown attached to the main support 103. The tensioner 8083 is applying the preload on the pipe 105 to properly seat the pipe 105 - within blocks V 8081 and 8082.
Figures 56A-56D are various views showing the release of the barrel 105, according to an embodiment. When the barrel lock 113 is pushed down, the swinging wedge 8253 disengages or releases pin 8254 to allow the barrel 105 to fall free of the firearm, as discussed here.
Figures 57A-57D are various views showing the gas system, according to an embodiment. Gas from a fired cartridge enters the gas system via the gas orifice of the pipe 7501. The gas flows from the gas orifice of the pipe 7501 to a gas measuring orifice 7502 with the gas block
7503. The 7502 gas measurement port determines, at least in part, the amount and pressure of gas provided in the gas system. The gas orifice is discussed in more detail with reference to figures 72-74 below. 7001 gas piston rings can provide an improved seal, as discussed here. Gas piston rings 7001 can be - arranged on a piston 7003, which can be arranged inside a cylinder
7004. Gas piston 7003 can activate bolt support 111 to operate the firearm. More particularly, the gas piston 7003 can rest on a protrusion 7506 formed on a front end of the bolt holder 111 to push the bolt holder 111 back when the firearm discharges. Lumps 121 can be formed on piston 7003 and can slide into guide slots 122 (figure 14A) to define the movement of piston 7003. A lightning rod 123 (figure 14A) can obscure, hide or diffuse lightning coming out of guide slots 122 when the firearm is discharged.
Overheating the barrel of a firearm can be alleviated by making it easier to change the barrel. Changing the barrel of a modern firearm, such as the M1I6 or M4, during combat with firearms is generally not practical. According to one modality, the barrel of a firearm can be changed quickly, even in adverse conditions, such as during combat with firearms. Thus, a soldier may have several, for example, four or five, pipes at hand and may change pipes each time a pipe becomes very hot, such as after a predetermined number of shots have been fired or a predetermined number of deposits have been made. used. The pipes can be reused afterwards - let them cool down. Thus, a soldier can generally continue to fire until the ammo supply runs out.
According to one embodiment, the ability to quickly change the barrel is facilitated by the use of a main support structure and bolt support, as discussed here. According to one modality,
the ability to quickly change the barrel is further facilitated by the use of an oscillating wedge, tensioner, and other features, as discussed here. The use of a main support allows the bolt support to move out of the receiver, at least to a certain degree.
According to one embodiment, a main support replaces the main support of a modern firearm. The main support may comprise a tube with a generally round cross section. The main support may comprise a tube with a generally rectangular, for example, square cross-section. The main support - can comprise a tube with any desired cross-section or cross-section combination.
The main support can guide the bolt support. A portion of the bolt support can move within the main support. That portion of the ferrule holder that moves within the main carrier can be attached to another portion of the ferrule holder that contains the ferrule. A portion of the bolt holder can move out of the main holder. That portion of the bolt support that moves out of the main support may contain the bolt.
For example, the bolt support may comprise a generally elongated tubular portion 150 (figure 4A) that slides within the main support. A portion of the ferrule support can be formed of a pipe butt. For example, that portion of the bolt support that moves within the main support can be formed of a pipe butt.
Surfaces of the generally tubular portion of the ferrule support can support or contact the inner wall of the main support to control the movement of the ferrule support. For example, the ferrule holder may have contact surfaces with the main carrier that are forward and rearward on the ferrule holder. These contact surfaces of the bolt support can slide into the main support and can facilitate guiding the bolt support, at least to a certain degree.
The ferrule support can have four surfaces 151 (figure 4A) that make contact with the main support that are forward in the ferrule support and can have four surfaces 152 (figure 4A) that make contact with the main support that are back in the support of the ferrule bolt. The ferrule support can have three contact surfaces with the main support that are forward in the ferrule support and can have three contact surfaces with the main support that are backward in the ferrule support. The ferrule support can have any desired number of - contact surfaces with the main support that are forward and any desired number of surfaces that are left behind in the ferrule support. The number of contact surfaces at the front does not have to be the same as the number of rear contact surfaces.
By providing forwards and backwards contact surfaces on the ferrule support, the configuration and dimensions of the ferrule support in other portions of the ferrule may be less critical. For example, the diameter of the bolt holder can vary substantially between the front and rear contact surfaces without adversely affecting the operation of the firearm. By providing forwards and backwards contact surfaces on the ferrule support, the stability of the ferrule support with respect to the main support is increased.
According to one embodiment, part of the bolt support can be inside the main support and part outside the bolt support can be outside the main support. The part of the bolt support that is outside the main support can be below the main support. Thus, the bolt support can comprise an upper portion (within the main support) and a lower portion (below the main support). The upper portion may be substantially larger than the lower portion. The upper portion can extend substantially towards the front of the chamber when the bolt is locked, in such a way that a telescopic bolt support is defined.
The lower portion may include the bolt.
The main support may have a slit shape in it to facilitate the connection of the upper portion of the main support to the lower portion of the main support.
The upper portion of the main support can be connected to the lower portion of the main support on a waist of the bolt support.
The waist may be a small width portion of the cross section of the bolt support.
The waist of the bolt holder can slide into the slot of the main holder.
The slot width is such that excessive lateral movement of the lower portion of the bolt support is inhibited.
Thus, the slot in the main support can guide the bolt support in the forward and backward movement of the bolt support as the firearm cycles.
Bolt support movement is movement not limited by a receiver, as is common in modern firearms.
Instead, movement of the bolt support can be limited by the main support.
An ear latch can have a handle or cam twisting pin that moves inside the slot and exits the slot (such as to one side of it) as the bolt ears reach their position further in order to rotate the bolt to fit the ears and lock the bolt in a firing position.
A release notch formed in the slot (as an extension of the slot to one side of the slot) can cause the cam pin to rotate when the cam pin is off-center by the support portion of the lower ferrule to rotate the ears and lock the bolt.
The notch - deliberation can be formed and positioned to allow the cam pin to rotate after the cam pin moves out of the shelter.
The use of a main support like this can facilitate the construction of a firearm with a quick-change barrel feature where the barrel falls down, by gravity, when the barrel is released from the firearm, for example , the main support of the firearm. A new pipe can be quickly snapped into place. Thus, the barrel can be quickly changed in battlefield conditions.
According to one embodiment, an oscillating wedge can be attached to the pivot on the main support. The oscillating wedge can fit a pin attached to the barrel to retain the barrel in the firearm. For example, the oscillating wedge can have two wedge tabs and each wedge tab can engage one end of the pin. A single pin can be attached by the two wedge tabs or two separate pins can be attached by the tabs.
A barrel lock can be formed with the oscillating wedge in such a way that the actuation, for example, pressing, of the barrel lock causes the oscillating wedge to rotate and release the barrel of the firearm. When the oscillating wedge rotates, it can slide against the tension caused by contact with the pin. The oscillating wedge can be ordered by spring to a position of the same that holds the barrel on the firearm. Thus, the barrel lock can move against the spring tension to release the barrel.
The oscillating wedge and the pin can be configured in such a way that approximately the same force, for example, tension, is applied by the oscillating wedge on the pin anywhere along the oscillating wedge.
The oscillating wedge can provide approximately the same force, regardless of where along the oscillating wedge the pin makes contact with the oscillating wedge.
The oscillating wedge can be a curved oscillating wedge. The pivot point and the oscillating wedge curve can be non-concentric. The pivot point and the curve of the oscillating wedge can be defined in such a way that the oscillating wedge provides approximately the same force regardless of where along the oscillating wedge the pin makes contact with the oscillating wedge.
For example, the pivot point and the oscillating wedge curve can be configured in such a way that, at the points of contact between the pin and the oscillating wedge, a tangent to any point on the oscillating wedge curve is at an angle of approximately 8 degrees with respect to a perpendicular to a line through that point and the pivot point of the oscillating wedge. This angle allows the oscillating wedge to slide easily during installation and removal of the barrel and also inhibits unwanted movement of the oscillating wedge because of the tension applied by the tensioner via the pin.
That is, the radius that defines the surface of the oscillating wedge can be taken from a point that is displaced in relation to the pivot point of the oscillating wedge. As such, the surface of the oscillating wedge may have a different radius compared to the radius taken from the pivot point of the oscillating wedge, as shown in figure 37.
More particularly, the angle of approximately 8 degrees can be present along the oscillating wedge at each point on the oscillating wedge where the pin can make contact with the oscillating wedge. That is, where —ever the pin makes contact with the oscillating wedge, the wedge is effectively at an angle of 8 degrees with respect to the force applied by the pin. Since this angle does not vary substantially along the oscillating wedge, it does not matter substantially where along the oscillating wedge the pin is positioned to attach the barrel to the firearm.
Regardless of where the pin is positioned along the oscillating wedge, the force applied by the pin to the oscillating wedge is substantially the same and the force required to push the barrel lock down to release the barrel does not vary substantially. Due to the 8 degree angle, expansion of the barrel does not cause the position of the pin on the oscillating wedge - to change substantially. Expansion of the barrel does not cause the pin to slide along the wedge.
The oscillating wedge can be defined by channels formed inside the tongues that receive the ends of the pin. The channels can be curved to define the oscillating wedge in order to pull the pin (and,
consequently, the barrel) closer to the main support as the wedge slides into closer contact with the pin. According to one embodiment, a tensioner can apply a predetermined amount of tension to the pin when the pin engages the oscillating wedge. The tension of retaining the barrel on the firearm. For example, the tension can hold the pipe against one or more V blocks that are formed in the main support. The V blocks can ensure proper alignment of the barrel with respect to the main support. The V blocks are sufficiently spaced in relation to each other in order to adequately stabilize the barrel with respect to the firearm.
The tensioner can be defined by a spring that at least partially surrounds the pipe. The tensioner can be arranged close to where the oscillating wedge is positioned on the firearm. The tensioner can be attached to the pin, in such a way that pulling the pin out of the barrel stretches the tensioner and thus applies tension to the pin. Thus, as the oscillating wedge pulls the pin out of the barrel, the tensioner applies tension to the pin which tends to pull the pin towards the barrel. Additionally, as the pipe expands because of the heating of the pipe during firing and thus moves radially out of the main support, additional tension is - accommodated by the tensioner.
The V blocks cooperate with the tensioner, pin and oscillating wedge to accommodate thermal expansion of the pipe, while maintaining alignment. Thus, as the barrel expands due to heat during firing, the desired alignment of the barrel with respect to the main support is maintained.
According to one modality, as the barrel expands longitudinally, it simply slides into the V blocks. As the barrel expands radially, the barrel does not push the oscillating wedge backwards (to the oscillating wedge barrel release position) against the spring tension. The oscillating wedge is not pushed back due to its angle of approximately 8 degrees. That is, the angle is not sufficient (sharp enough) to allow the pin to move the oscillating wedge. Instead, the angle is such that the oscillating wedge can move the pin, but not vice versa. As the barrel expands radially, the tensioner accommodates a radial expansion basket.
The tensioner can have a preload of approximately 700 pounds, for example. This preload can accommodate the thermal expansion of the pipe which causes the pipe to move out of the main support. This preload is sufficient to hold the barrel firmly in place in the firearm, while also immediately facilitating the movement of the barrel lock to release the barrel, when desired. As those skilled in the art will realize, other configurations of the oscillating wedge and tensioner (such as the preload provided in this way), may be similarly suitable.
Thus, the oscillating wedge presses the pin with a fair amount approximately equal to that necessary to maintain the barrel in the firearm. In this way, there is a tendency that only a minimal amount of force has to be applied downwards in the pipe lock in order to release the pipe. That is, excessive force does not need to be applied to the barrel lock in order to overcome the excessive force applied by the oscillating wedge on the pin.
The pipe can have an angle of 8 degrees formed in an annular protrusion that extends radially from it and which is received inside the rear block V. This 8 degree angle can guarantee a desired adjustment of the protrusion inside the V block, still inhibiting forward and backward movement of the pipe inside the V block. Thus, the 8 degree angle readily facilitates the installation and removal of the pipe in the V block. still substantially inhibiting longitudinal movement of the barrel with respect to block V. The front block V may not have an angle like this. The front V block can be configured to facilitate a certain amount of longitudinal movement of the pipe, in order to accommodate thermal expansion of the pipe.
According to a modality, the ability to quickly change the barrel is provided while still maintaining firing accuracy without requiring a new zeroing of the sight. Accuracy is maintained, at least in part, by using the V blocks and the tensioner. The V blocks and the tensioner cooperate to provide a rigid assembly that places a new pipe in substantially the same alignment as the old pipe.
According to one modality, as the pipe is released it goes through a two-stage eccentralization process. During the first stage of the eccentralization process, the pipe moves slightly forward (about a wall thickness of the pipe). During the second stage of the eccentralization process, the pipe moves forward substantially more. Two eccentralization surfaces are provided on the firearm, near the rear end of the barrel. These two eccentralization surfaces make serious contact with the rear end of the barrel as the barrel falls from the firearm in a way that pushes or eccentralizes the barrel forward as the barrel falls.
More - in particular, a first eccentralization surface can be formed on the lower receiver to move the pipe slightly forward during release of the pipe and a second larger eccentralization surface can be formed on the main support to move the pipe further forward as that the pipe falls even more. The two stages of the eccentralization process ensure that the barrel moves forward sufficiently to fully disengage the firearm. In particular, the barrel moves forward sufficiently to disengage the firearm without making contact with the tank as the barrel falls. Both of these situations ensure that the barrel detaches properly from the firearm and ensures that the barrel falls in a predictable manner in order to avoid damage to personnel or equipment due to the hot barrel.
To release the pipe, the pipe lock is pushed down.
Pushing down the barrel lock moves the oscillating wedge in order to release the pin captured by the oscillating wedge. Once the pin is released, the barrel is free to engage by gravity. The barrel immediately falls slightly, is pushed forward by the eccentralization process, and disengages the firearm.
A safety mechanism, including a safety selector switch, can be configured to eccentralize the trigger forward in a way that prevents the trigger from operating. The safety mechanism can be configured to prevent the bolt holder from being released - during firearm open bolt operation. This can, for example, inhibit unintentional firing of the firearm when the firearm is disengaged. The safety mechanism can also lock the dog to prevent its action.
According to one embodiment, many of the internal functional components of the firearm may be part of a common set. For example, the trigger group, the toggle switch, the safety key, the trigger lock (prevents the trigger from being pulled when the loading lever is pulled back), etc., may be part of a block assembly. trigger.
Thus, at least some of the firearm's internal mechanisms can be attached, contained and / or mounted on a common frame or frame to define the trigger block assembly. The use of the trigger block assembly facilitates the assembly of these components outside the firearm. Once assembled, the components can be attached to the firearm, for example, the bottom receiver, and then secured in place, such as with one or more pins, screws, or other fasteners.
As those skilled in the art will appreciate, assembling such small complicated components within the lower receiver can be difficult, time-consuming and require a substantial amount of skill. Like this,
such an assembly can be relatively expensive. In contrast, assembling the same parts outside the bottom receiver can be substantially less difficult, substantially less time-consuming, and require substantially less skill. As such, mounting the trigger block assembly outside the lower receiver and then fitting the trigger block assembly to the lower receiver to facilitate the assembly of these components can be advantageous.
According to one embodiment, two gas piston rings are configured to be received at least partially within a piston groove. A key can be formed on each of the rings and an interstice that is generally complementary to the key can be formed on each of the rings. Thus, the interstice of a ring can be configured to receive at least a portion of the key from another ring. In this way, the rings can be interlocked in such a way that they cannot rotate to a position where the interstices in the rings align in a way that allows hot gases to pass through the interstices.
As those skilled in the art will realize, when hot gases flow through the interstices, the force provided by the gases to extract the used capsule and place a new cartridge in the chamber is undesirably reduced. Additionally, when hot gases flow through the interstices, the hot gases can burn the ends of the rings and thereby undesirably enlarge the interstices.
According to one embodiment, wings or protrusions 121 can be formed on the gas piston and the protrusions can slide into the guide slits 122 of the cylinder. The wings can cooperate with the guide slots to maintain a desired piston orientation, for example, to inhibit piston rotation. The wings can limit the backward movement of the gas piston. The wings can limit the movement of the piston backwards by supporting a front end of the main support. The wings also facilitate the installation and removal of the gas piston inside the cylinder. A stop or other mechanism can similarly be used to limit the backward movement of the gas piston.
According to one embodiment, the gas piston is not attached to an operating rod. The firearm gas system can be configured in such a way that a rear surface of the gas piston strikes a front surface of the bolt holder in such a way as to cause the bolt holder to move backwards during cycling of the firearm . Since the gas piston is not attached to an operating rod, the gas piston, as well as its rings, is easy to change. That is, the gas piston does not have to be removed from a connecting rod in order to change the gas piston and / or the gas piston rings.
According to one embodiment, the slits within which the wings move also define gas sighs that release gas from the cylinder into the atmosphere. Cover plates formed on the front end of the main support can define a gas hole lightning suppressor that can obscure the lightning from the cracks in order to make such lightning less visible and also in order to reduce the potential for injury from the exhausted hot gas .
The gas hole lightning suppressor can be defined by two flanges that substantially cover the cracks. The flanges can also guide the new pipe as the new pipe is being installed, such as during a pipe change. Flanges can guide the cylinder (which is attached to the barrel) towards the main support as the new barrel is attached to the firearm.
According to one embodiment, a selector mechanism can be used to select between closed bolt operation and open bolt operation on the semiautomatic rifle and the semiautomatic / machine gun. The machine gun can be configured to fire only with the bolt open.
The selector mechanism can be configured in such a way that changing the selection from closed bolt to open bolt involves merely moving a selector lever. The selector mechanism can be configured in such a way that changing the selection from open bolt to closed bolt requires an extra step. For example, changing the selection from open bolt to closed bolt may require a button to be pressed. The button can be part of the selector switch, or it can be separated from it. For example, the button can be in the middle of the selector switch.
Requiring an extra step to be taken in order to switch from open bolt operation to closed bolt operation helps ensure that proper consideration is given to the property of this change. As those skilled in the art will realize, switching from open bolt operation to closed bolt operation can result in overheating the dangerous pipe if ammunition is placed in the chamber while the chamber is hot. For example, the barrel may overheat if ammunition is placed in the chamber before the chamber has been properly cooled after sustained rapid firing of the firearm. Overheating of the pipes probably does not occur during open bolt operation, since the cartridge is fired as soon as it is placed in the chamber. Thus, this extra step when switching from open bolt operation to closed bolt operation is a desirable safety feature. The extra step can make a user more carefully consider whether or not the camera had adequate time to cool. It is common practice to pull the trigger on a firearm and facilitate the bolt forward in order to avoid making any noise that can alert the enemy of the user's presence. For example, a soldier using the MI16 can be instructed with this technique. According to one modality, when firing with a closed bolt, the user can pull the trigger to release the bolt forward. Thus, the user can move the bolt forward in a way to more easily place ammunition in the chamber in order to make detection by the enemy less likely. However, it may not be appropriate to move the bolt from an open to a closed position, as discussed here. According to one modality, when the bolt is opened, the trigger cannot be pulled to move the bolt forward unless a button is pushed. When firing with an open bolt, the bolt must remain open (backwards) in order to promptly facilitate the firing of the firearm and to further facilitate the cooling of the chamber. According to one embodiment, a main spring guide contains and / or at least partially defines an anti-recoil mechanism that attenuates undesirable backward recoil of the bolt after the bolt places ammunition in the chamber. As those skilled in the art will realize, bolt recoil is undesirable because the bolt recoil can allow the dog to strike the striker when the bolt is not fully forward, thus resulting in 15 "muzzle strike and a potential imperfect shot.
A weight of the main spring guide can strike the bolt in a way that tends to reduce its recoil. The mainspring can push the weight forward along with the bolt support. For example, the weight can strike the bolt and push the bolt forward shortly after the bolt has placed ammunition in the chamber, for example, shortly after the bolt has started to jump. In this way, the bolt is inhibited from jumping backwards, as it would be otherwise. The weight can be held backwards before the bolt is loaded into the chamber by a spring of the anti-recoil weight (different from the main spring).
The weight can be configured to slide along a portion, for example, near the front end, of the main spring guide. The weight can generally surround the main spring guide. The weight can be arranged between the mainspring and the anti-recoil weight spring in such a way that the mainspring requests the weight forward and the anti-recoil weight spring requests the weight backwards.
Thus, the mainspring serves two functions: the mainspring pushes the bolt holder forward during cycling of the firearm and the mainspring pushes the anti-kickback forward equally. —Placing the anti-kickback weight on the main spring guide solves the problem of where to place the anti-kickback weight and allows the main spring and the main spring guide to serve two functions, that is, cycling the bolt support and inhibiting undesirable retreat of the bolt.
An interstice can be provided between the anti-kickback weight and a stop formed on the spring guide.
The length of this interstice and the spring intensity of the anti-recoil weight can define the moment when the anti-recoil weight strikes the stop (and thus effectively strikes the bolt). Thus, the interstice can be configured in a way to minimize undesirable bolt recoil.
One or more flaps, for example, two, can hold the anti-kickback weight in place on the spring guide.
According to one embodiment, a dog assembly has a joint.
One end of the joint is attached to a pivot on the lower receiver and the other end of the joint is attached to the dog. A spring guide can be attached to a pivot on the bottom receiver and received inside a dog hole in such a way that a spring on the spring guide calls the dog into the actuated position (a position that causes ammunition to be fired) . The use of the joint provides a configuration in which the dog has a relatively large displacement and a relatively large reach.
This large displacement and wide reach allows the dog to move on the stop of the last 4011 ammunition (figure 11J). This large displacement and range allows each one to be bolted further forward when ammunition is in the chamber.
As the bolt holder retracts (such as when firing or firing the gun), the bolt holder pushes the dog back to arm the dog. At one point in the displacement of the bolt holder, the bolt holder pushes the dog down and then the bolt holder runs over the dog. As the bolt holder moves forward when the gun is fired, the bolt holder discovers the dog. The dog does not start moving (to fire the ammunition) until the bolt holder is almost all the way forward. The dog strikes the striker at about the same time that the bolt is locked, or after the bolt is locked.
Since the bolt support runs over the dog and keeps the dog down and under the bolt support, the bolt support does not have to continually push the dog down to maintain this armed position. Instead, the dog is trapped under the bolt holder and cannot move (in order to fire a cartridge into the chamber) until the bolt first moves forward. When the bolt moves forward, the dog oscillates over the last ammunition stop, with the dog's movement being at least partially restricted and defined by the dog's articulation.
The dog can be an aluminum dog with a steel face. The dog can be all steel. The dog can be comprised of aluminum, titanium, steel, or any combination of these. The dog can be made of any desired material.
The dog can be hardened by anodizing where the bolt support slides against the dog. The dog can be tempered or treated in the desired way where the bolt support slides against the dog or any other part or surface of the dog.
According to one modality, a stock has grooves - formed on its head to define a cable. The grooves can define a handgrip that improves a user's ability to firmly hold the stock while firing the firearm with a two-foot support from an inclined position. For example, one or more horizontal grooves formed on the head can substantially inhibit the vertical movement of the stock with respect to a user's hand. That is, such grooves can inhibit unwanted head slipping when the head is held during firing. For example, one of the grooves can be formed to define a cable so as to receive the thumb of a user during firing of the firearm with a two-foot support from an inclined position. The firearm head grip with the user's thumb in the groove can be made in such a way that the groove substantially inhibits unwanted slipping of the user's thumb.
The stock can be a folding stock, a collapsible stock and / or a removable stock. The stock can be a rigid stock that does not fold or collapse and is not easily removable. The stock can be any type of stock desired.
According to one embodiment, a measured gas orifice is provided. The measured gas orifice can be separated from the gas orifice formed in the pipe. The measured gas orifice, instead of the gas orifice formed in the barrel, determines the amount of gas that is used to cycle the firearm. Thus, as the gas orifice that is formed in the pipe widens over time because of the erosive effects of the hot gases in it, the operation of the firearm, such as cycling time, is not substantially affected. The measured gas orifice can be in a gas block that is part of the firearm sight assembly, for example.
The measured gas orifice can be adjustable in order to compensate for erosion of the gas orifice in the barrel and in order to provide a certain degree of control over the operation of the firearm, for example, the cyclical rate of the firearm. The measured gas orifice can be easily changed. A gas orifice reconstruction kit that includes a new measured gas orifice can be provided. Thus, a more uniform cycling and greater reliability of the firearm can be provided.
According to one embodiment, the measured gas orifice may comprise two tubular elements which lock within a gas block of the firearm. For example, the measured gas orifice can comprise a first tubular element that is inserted into the gas block and a second - tubular element that is inserted into the gas block and the first tubular element.
A screw, such as a clamping screw, can be screwed into the first tubular element to lock the first tubular element in the second tubular element and lock the first tubular element and the second tubular element in the gas block. The turning of the screw adjusts the gas flow.
According to one embodiment, a heavy-duty extractor can be used to extract used cartridges from the chamber. The heavy-duty puller can take more used cartridge than a modern puller. The heavy-duty puller can be thicker, heavier and wider than a modern puller. The heavy-duty puller can have two pins and two springs that request the puller in position to pick up a used cartridge, as opposed to the single pin and spring that is common in modern firearms. Thus, a more reliable extraction is provided.
According to one embodiment, a bar extends substantially along the main support above the bolt support.
The bar can prevent disassembly, that is, disassemble the fully compressed spring loaded firearm. The bar can prevent disassembly, interfering with the operation of the disassembly lever when the bolt is in the open position (and thus when the mainspring is completely compressed). As those skilled in the art will realize, disassembling a weapon — a fully compressed defogocoma mainspring can cause the mainspring to quickly and unexpectedly extend in a way that can cause injury.
A downwardly extending flap formed near a front end of the bar can extend downwardly into a groove formed in the ferrule support when the ferrule support is close to its forward position (and the main spring is thus not completely compressed). When the bolt holder moves forward, the flap can rest on the end of the groove and the ferrule holder - you can pull the bar forward in such a way that the bar no longer interferes with the operation of the disassembly lever.
Thus, when the bolt holder is completely forward, the disassembly lever can be actuated to disassemble the firearm.
More particularly, a surface of the bar can make contact with a flat surface of the disassembly lever pin when the bar is in a position further behind it.
When the flat surface of the bar makes contact with the flat surface of the dismount lever, the dismount lever is prevented from rotating to its dismount position.
That is, when the bolt holder is forward, the bracket is pulled forward by the bolt holder to pull it away from the flat part in the disassembly locking pin.
The semi-automatic rifle and rifle / machine gun can fire with the bolt closed (if closed bolt operation is selected). The semiautomatic rifle and the rifle / machine gun may have a dog to facilitate shooting with a closed bolt.
The bar can be configured to prevent the dog from being released until the bolt is all the way forward or almost all the way forward, in order to ensure that the bolt is locked when the firearm fires.
During semi-automatic firing, the bar may allow the bolt to lock before the dog strikes the striker.
During fully automatic firing, the trigger can remain in the pulled position while the firearm continues to fire, so that the bar delays the dog until the bolt has moved forward sufficiently.
The same bar can perform both functions.
Thus, the same bar can prevent disassembly of the firearm when the mainspring is fully compressed and can prevent the dog from being released prematurely.
According to one embodiment, the disassembly lever has a safety lock pin to prevent inadvertent rotation of the disassembly lever to its disassembly position and has a safety lock pin to prevent inadvertent rotation of the disassembly lever to its dismantling position. do not disassemble before the firearm is reassembled. Both of these functions can be performed by the same safety lock pin.
According to one embodiment, the indentation can be attenuated - as described in U.S. patent no. 4,475,438 granted to Leroy J. Sullivan on October 9, 1984. According to this method, the impulse time caused by the firing of the firearm is extended to extend substantially throughout the firearm cycle period .
A dirt cap can open approximately 7 degrees to allow the handle to move backwards. Moving the handle backwards, for example, arming the firearm, can cause the dirt cap to open. If the handle is not in its forward position, the trigger cannot be pulled.
According to one modality, the machine gun does not have a dog.
The machine gun may have a striker retaining pin that is configured to facilitate striker removal and is configured to transfer forward movement from the ferrule holder to the striker to cause a cartridge to fire. Removing the striker retaining pin allows the striker to be removed. When the bolt holder moves forward, the striker pin retainer causes the striker to move forward.
According to one embodiment, the cam pin may have a vertical hole formed in it that receives the tip of the striker to assist in removing the cam pin. Thus, the cam pin can be removed by placing the striker tip in the hole in the cam pin. The striker tip can also be placed inside the pin of the hole cam to assist in assembly. According to a modality, for the machine gun, the eccentralization surface of the open bolt arm can be activated against the eccentralization surface of the disconnector with the bolt support acting on the trigger. This can be done while the open bolt arm is still being driven by the bolt support. Features of one type of firearm described herein can be used in another type of firearm described herein, in the desired manner.
- Additional features can be incorporated into any of the types of firearms described here. Features can be removed, disabled or not used in any desired type of firearm described here. Thus, the features described in relation to each type of firearm can be mixed and matched in the desired manner and are only by way of example, not limitation.
Above-described modalities illustrate, but do not limit the invention. It should also be understood that numerous modifications and variations are possible according to the principles of the present invention. In this way, the scope of the invention is defined only by the following claims.
One or more embodiments provide a gas-powered automatic gas-fired firearm that generally operates as follows. Like all slit-loading repeaters, they have to perform eight ammunition handling functions between one shot and the next. She has to feed, put in the chamber, lock, shoot, - unlock, extract, eject the ammunition cartridge and arm the weapon ready for the next cycle. The bolt group is involved in all eight of these functions. As a mainspring drives the bolt group forward, it completes the feed by pushing the top cartridge forward out of the tank and tilting the bullet end forward on a feed ramp and into the chamber and turning the bolt head to lock it into the cartridge inside the barrel and then fire the cartridge. This completes half the forward motion of the bolt cycle. As the bullet moves through the barrel, it passes through a hole gas hole made in the barrel wall through which high pressure gas enters the cylinder and drives the piston backwards, thus throwing the bolt holder back and compressing the mainspring. During the first backward movement of the bolt holder a helical cam in the holder rotates the bolt head to unlock the barrel bolt head and then - pull the bolt head back the rest of its combined backward cycle. A puller claw on the bolt head pulls the shell of the fired cartridge into the chamber and an ejector strikes or pushes the cartridge base opposite the puller, pivoting the cartridge around the puller and out through an ejection hole in the frame revolver. The continued movement of the bolt head and the combined bolt holder backwards uncovers the new upper cartridge in the tank that feeds it upward within the bolt head return path while the movable backrest and bolt arms the firing dog spring loaded and moves (backwards) a bolt stop which is lifted by the tank follower after the last cartridge has been fed from the tank and which catches and retains the bolt and support group so that the tank empty can then be removed and replaced with a full one and ready to resume firing without arming the weapon by hand. A gripping means can be provided in the event of an imperfect trigger or other malfunction of the cycle.
One or more modalities provide a main tubular support that guides the forward and backward movement of the bolt, aligns the bolt and its locking ears with the barrel and barrel ears, and prevents locking movement (in this case, rotation of the bolt). bolt) until the bolt has reached the lock position and then allows the bolt to lock
T7 in the barrel. The main support differs from modern receivers, for example, in that the main support does not contain or involve the bolt that it is twisted. Instead of both the bolt and barrel assemblies being outside and below the main support, which contains at least partially and guides at least partially the ferrule support. As seen from behind, the bolt holder can be configured as a thin "figure 8" waist.
As seen from the side, the upper part of the "figure 8" ferrule support is a long tubular section with contact points forwards and backwards that center it within the main support. This upper section of the bolt holder slides back and forth inside the main holder and contains the main spring.
A guide slot in the base of the main support can be cut from the back to approximately the middle of the main support. This slot is the passageway for the waist of the bolt holder, which is connected to the lower section of the bolt holder. The slot allows the bolt holder to slide, while still keeping the bottom section of the bolt holder substantially in line with the barrel.
The lower section of the bolt holder may be smaller than the upper section. The bottom section of the bolt holder may contain the bolt - you can keep the bolt in line with the barrel.
A cam pin on the bolt can extend upwards through a helical cam slot in the lower support section. The top of the cam pin can be the same width as the waist support and slides back and forth in the guide slot of the main support, which can prevent the cam from rotating the bolt until the cam pin reaches the cutout. In this position, the bolt ears may have entered between the barrel ears and the bolt may be released by the cutout and rotated to lock by the helical angle of the cam as the support completes its forward motion until it stops at the rear most surface of the pipe.
According to one modality, a main support structure is provided that facilitates the precise quick change of the pipe.
When in place, the barrel is below the main support and the rearmost surface of the barrel is approximately at the midpoint of the main support length.
A pipe cross pin (figure 52C) can be permanently aligned parallel to the pipe ears and held in place by a strip (shown simplified in figures 52 and 53). An oscillating wedge (figures 52A-53B) can pull the cross pin and barrel up firmly on the V blocks (figure 52C) and can pull a barrel lock flange upward into a lock notch (figures 52C and 53C ). The main support and barrel assembly shown in figures 53A-53C are thus kept in a substantially "accurate" location with respect to each other. "Accurate" in this case means any individual barrel set that can be repeatedly installed and removed from a weapon set and that returns substantially to the same position on that weapon.
Each barrel has a front sight adjustment and a gas orifice adjustment, so that any number of pipes can be installed and "zeroed" in a weapon, and everything will remain in sight and will properly operate that particular weapon if exchanged one with the other. another.
In this way, any particular weapon can have many pipes dedicated in both 5.56 and 6.8 and in different weights and lengths, some with accessories, some without, like suppressors or 40 mm launchers.
The pipe, once installed, cannot move up, down or sideways, cannot move forward and back, and cannot rotate.
The patterns of the locking ear of both the bolt and the barrel are thus aligned within the combined tolerance of the positioning surface on the main support, bolt and barrel.
Adequate interstices are provided in the ear patterns to accommodate tolerances plus thermal expansion.
Two spring assemblies consisting of a plunger, spring and plug are housed in the two accessory rails that are attached to either side of the main support. The accessory rails have an interstice slot to accommodate the oscillating wedge arms, which cross to fit both ends of the pipe's cross pin. The angled wedge surfaces on the oscillating wedge are driven forward by the force of the spring assemblies to extract the transverse pin and barrel upwards and tightened on the V blocks.
If the bolt group moves forward with the bolt locked in the barrel, then the oscillating wedge blocker will collide on top of the upper ferrule support so that the oscillating wedge cannot swing to release or load a barrel assembly. The oscillating wedge can only be operated if the bolt group is locked back as in the open bolt firing position or when the bolt tongue is automatically activated by the tank follower as the last ammunition is fired. Thus, without additional attention, the user can exchange hot pipes for cold pipes for maximum sustained firing. All the user needs is to hit the top plate of this wedge, as with a "karate chop" movement, and the hot barrel is ejected. No tools or protective mechanisms are needed (such as to prevent burning).
The barrel assembly is designed for machine gun firepower. This means that the pipe temperature of 1,500ºF (816ºC) and the precise tight fit of the V blocks and the oscillating wedge that holds the transverse pin can still accommodate the largest pipe sizes due to thermal expansion, which reaches 0.009 "(0.229 mm) ) more in diameter and 0.057 "(1.448 mm) in length between blocks V. If the strip shown in figures 52 and 53 is used, either the strip, cross pin, wing wedge, main support, or barrel would bend or damage severely by thermal expansion.
The tensioner shown in figures 5S4A-55D can be subjected to bending by such expansion. The tensioner can be a spring that is strong enough (when its force adjustment screw is initially adjusted to 700 Ib (318 Kg) of preload) to keep the barrel firm in the V blocks, thus accommodating the vibration and shock of the firing and off-center force of the gas system. Then, the tensioner's flexibility as the barrel expands downwards increases the force by 1,100 lb (499 kg), which is well short of a force to bend or permanently damage the parts involved.
The oscillating wedge can make contact with the base of the pin at an angle of approximately 8 degrees. Thus, the more the wing oscillates, the more it raises the pin and barrel until the barrel is pulled up against its "V" blocks. The wedge can thus provide a suitable adjustment to any variation of - dimensional tolerances in any number of barrels, so that it obtains a precision fit for the accuracy of the rifle without additional cost of extraordinarily accurate manufacturing tolerances and without loss of interchangeability.
Gas-operated firearms are undesirably subject to extraction failures. When an extraction failure occurs, a fired cartridge is not extracted completely from a firearm chamber. Such extraction failures prevent the next ammunition from being placed in the chamber and thus jam the firearm.
In some firearms, the bolt can disengage the next cartridge from a deposit and can strike the next unstrung cartridge on the cartridge not placed in the chamber or partially placed in the chamber. In a firearm operated with a mechanism that dispenses with the locking mechanism of the open bolt breech with a fixed striker such as a submachine gun, this can result in a dangerous successive firing of the next cartridge when it is prevented from entering the chamber.
Such extraction failures can be caused by insufficient spring force to keep the extractor closed. Such failures can also be caused by the breaker of the extractor. For example, repeated use of the extractor can cause a crack to form in the extractor or its associated spring. The tension crack can propagate until the puller or spring is weak enough to break.
This problem is particularly prevalent in fully automatic firearms, because of the high number of cycles and the most extreme heat thus observed.
One problem is that there is insufficient spring force to keep the extractor closed because of the extreme vibration common to fully automatic firearms.
According to one embodiment, the extractor may be wider, have a wider claw, and may have more spring force that prompts the extractor to a closed position in order to more firmly grasp a cartridge being removed from the barrel.
Figures 58-61 show a 9100 extractor, according to an embodiment.
Extractor 9100 has a general "L" shape defined by an upper portion 9101 and a lower portion 9102. Extractor 9100 also has a heel 9103, a claw 9104, and a cock 9105. Extractor 9100 has a closed position and a open position.
The 9100 puller is generally in the closed position when the 9104 jaw is not fitting a missing cartridge.
The spring force applied to the heel 9103 in the direction indicated by the arrow 9106 can cause the puller 9100 to pivot around the cock 9105. The spring force can be applied by two springs 9501, 9502 (figure 67) that cooperate with two pistons 9503, 9504 (figure 67), in order to request the 9100 extractor to its closed position.
This pull force causes the 9104 gripper to grip or insert a cartridge more firmly.
The 9100 puller may also have a cutout 9107 that is configured to support a puller stop pin 9506 (figure 67) to limit the pull of the puller backward 9100, as discussed here.
The 9100 extractor may also have a width, dimension W, which is substantially larger than the width of a modern extractor.
For example, the width, dimension W, of the 9100 extractor can be increased by approximately 28%, compared to a modern extractor. For example, the width, dimension W, can be between approximately 6 mm and 8 mm and can be approximately 7.77 mm. Thus, the 9100 extractor can be stronger, more robust, and less susceptible to extraction failures compared to modern extractors.
Figures 62 and 63 show a bolt 9200, according to an embodiment. Bolt 9200 can have a body 9201 within which two spring holes 9202 and 9203 are formed. Each spring hole 9202, 9203 can receive and retain one of the springs 9501, 9502 and one of the plungers 9503, 9504.
Thus, bolt 9200 can have two springs 9501, 9502 in a side-by-side and generally parallel configuration. The two springs 9501, 9502 can apply force to the heel 9103 of the 9100 puller to request the 9100 puller to its closed position.
The two springs 9501, 9502 can apply greater force (compared to a single such spring) on the 9100 extractor in order to make the 9100 extractor better fit the cartridge rim. Thus, the use of two springs 9501, 9502 can mitigate extraction failures.
Hasp 9200 may have a cavity 9204 formed therein. The cavity 9204 can receive and retain at least partially the 9100 extractor.
The cavity 9204 can facilitate the installation of the springs 9501, 9502 and the plungers 9503, 9504 in the spring holes 9202, 9203.
The cavity 9204 can be opened at the top. The cavity 9204 can be opened on one side of it and closed on the other side of it. For example, cavity 9204 may have a wall 9511 on one side of it and - it may not have a wall like this on the other side of it. Arranging the cavity 9204 open on one side and closed on the other side of it further facilitates the manufacture of the bolt 9200, maintaining even greater resistance around the cavity 9204 than would exist without the existing wall 9511.
The cavity 9204 may have a groove 9206 formed therein. Groove 9206 can receive the cock 9105 from the extractor. The cock 9105 can cooperate with the groove 9206 to define a pivot around which the extractor 9100 (particularly its claw 9104) can rotate several degrees. Spring holes 9202, 9203 can be formed behind cavity 9204. Spring holes 9202, 9203 can be approximately parallel to each other. The spring holes 9202, 9203 can be approximately parallel with respect to a hole in the 9207 striker, at least within approximately 5 °.
Fig. 64 shows an end view of bolt 9200, according to an embodiment. Hasp 9200 may have a face of hasp 9303 formed in front of it. Hasp 9200 may have a plurality of ears 9301 formed on it, for example, seven. The ears 9301 can rotate to lock the bolt 9200 in a corresponding ear of the plurality of ears in the barrel before firing a cartridge.
For example, bolt 9200 may have an eight-ear pattern with one ear (the ear that would be at the top of the pattern shown in figure 64) removed to accommodate the width of the 9100 puller and facilitate the drilling of the two 9202 spring holes .9203 side by side without compromising its intermediate wall, for example, being so thin as to break. Removing the ear can also better accommodate the installation of springs 9501, 9502 and plungers 9503, 9504 in spring holes 9202, 9203.
Figures 65 and 66 show cross-sectional views of bolt 9200, according to an embodiment. A 9401 extractor stop pin hole can be configured to receive an extractor stop pin - 9506 (figure 67). The 9401 extractor stop pin hole can be formed at least partially inside the 9204 cavity. The 9401 extractor stop pin hole can be formed near a rear part of the 9204 cavity.
The 9506 puller stop pin can limit the pull of the puller 9100 to the rear. For example, the extractor 9506 stop pin can limit the movement of the extractor 9100 to the rear sufficiently to prevent pivot stop 9105 from escaping from groove 9206.
The claw 9104 defines a cam or ramp 9111 (figure 61) on a front surface thereof. For firearms with cartridges with deep extractor recesses, a relatively sharp ramp 9111 is required to raise the 9104 grapple up to or above the rim. As the ramp 9111 becomes steeper, it is more likely that the puller 9100 will move backwards instead of having the claw 9104 lifted over the cartridge rim when the cartridge rim is pressed into the face of the bolt 9303 (figure 64). By placing the extractor 9506 stop pin in the extractor 9401 stop pin hole, this undesirable movement behind the extractor 9100 can be mitigated. Thus, the 9506 puller stop pin can help keep the 9100 puller in place during firearm operation.
The stop pin of the 9506 puller can be installed on those 9200 bolts where it is necessary, for example, where a sharp ramp 9111 is present. The stop pin of the 9506 puller can be omitted in these 9200 bolts where it is not needed, for example, where a sharp ramp 9111 is not present. In any case, the hole of the stop pin of the 9401 extractor can be provided so that the stop pin of the 9506 extractor can be installed according to the need.
A recess 9107 can be formed in the extractor 9100 to partially receive the stop pin from the extractor 9506. The size, for example, depth, of the recess 9107 can define the movement limit of the extractor backward 9100.
Figures 67 and 68 show perspective views of bolt 9200, according to an embodiment. As you can see, each spring 9501, 9502 has a plunger 9503, 9504 in front of it and plunger 9503, 9504 can rest on the heel 9103 of extractor 9100. The force applied by plungers 9503, 9504 can request extractor 9100 to a closed position in which the 9004 claw of the 9100 puller is closest to a center line 9250 (figure 62) of the bolt 9200. The open position of the 9100 puller can be considered a position in which the 9104 claw is no closer to a center line 9250, such as when the claw 9104 of the extractor 9100 is fitted to a cartridge rim.
The load force applied to springs 9501, 9502 pushes the cock 9105 of the puller 9100 forward, into the groove 9206. The load force applied to springs 9501, 9502 also pushes the claw 9104 to pivot downwards, as for within a recess defined in a cartridge by the cartridge rim. Thus, when a cartridge has been placed in the chamber and the locking ears 9301 of bolt 9200 are fully engaged (bolt 9200 is locked), then jaw 9104 of extractor 9100 is engaged with the cartridge. The pull force pushes the 9100 puller from an open position to a closed position.
An ejector hole 9514 may contain an ejector (not shown) to push a cartridge fired from the bottom receiver 102 of the 9600 firearm (figure 6) as the bolt moves back.
Drain holes 9214 facilitate the drainage of fluids from spring holes 9202, 9203. If the assembled bolt 9200 becomes soaked with cleaning fluid, for example, then the cleaning fluid can be drained from spring holes 9202, 9203 via the holes Drain 9214. Otherwise, the incompressible cleaning fluid may interfere with the proper operation of the extractor
9100.
An eccentralization surface 9215 can facilitate the arming or rotation of bolt 9200 to fit ears 9301. This can be done according to well-known principles.
Fig. 69 is a flow chart showing the operation of the firearm according to a modality. The firearm can be cycled either by arming the firearm or firing the firearm, as indicated in block 9701. When the firearm is cycled, a new cartridge can be removed from its storage.
The ramp 9111 of the claw 9104 of the extractor 9100 can rise over a rim of the cartridge, as indicated in block 9702. The stop pin of the extractor 9506 can limit the movement of the extractor 100 backwards as the cartridge is placed in the chamber. The 9506 puller stop pin can be either installed or omitted, according to the need for a particular firearm.
The two springs 9501, 9502 can apply force to extractor 9100 as the cartridge is extracted after firing the firearm, as indicated in block 9703. The cycle can then be repeated.
The use of a wider extractor provides greater fit of the extractor with the rim of a cartridge to reduce the occurrence of extraction failures. The use of two springs further facilitates the forced insertion of an extractor claw with a cartridge rim in order to mitigate the occurrence of extraction failures.
Figures 70 and 71 show two gas piston rings 7001, according to an embodiment. Each piston ring 7001 has a key 7002 formed in it. The key 7002 is configured to be received within an interstice of a piston ring 7001. Two piston rings 7001 can be nested or positioned next to each other in such a way that the key 7002 of each piston ring 7001 is received within the interstitial 7003 of each of the other piston rings 7002.
Since the two piston rings 7001 can only rotate substantially in unison with each other, the interstices 7003 of the two piston rings 7001 cannot align with each other. Therefore, gas cannot flow easily beyond the two piston rings 7001 and a greater gas seal is provided hereby.
Figures 72-74 show the gas measurement port 7502, according to an embodiment. The gas measurement port 7502 may comprise a first tubular element 7511 which passes through a second tubular element 7512, wherein the first tubular element 5711 and the second tubular element 7512 are held within the gas block 7503 via a 7513 screw which bolts to the second tubular element 7512. Screw 7513 can expand a portion of the second tubular element 7512 as the screw 7513 is tightened, so that the second tubular element 7512 frictionfully engages the gas block 7502. The amount gas provided by the gas measurement port 7502 can be - set by adjusting the screw 7513. Turning the screw 7513 can vary the size of an opening 7515 through which the gas flows into the first tubular element 7511.
Gas flows from the pipe 105 through the gas orifice of the pipe 7501, through the passage 7561 formed in the gas block 7503, and in the first tubular element 5711. Gas flows through the opening 7515, in addition to the screw 7513, and into the cylinder 7004 , where the gas can act on piston 7003.
Since the gas measuring orifice is disposed outside of pipe 105, gas measuring orifice 7502 is not subject to erosion in the same way that the gas orifice in pipe 7501 is subject to erosion. Thus, the use of a 7502 gas measuring orifice ensures more uniform operation of the firearm over an extended period of time.
Figures 75-81 show a tensioner 8083 to provide a preload for attaching the pipe 105 to the main support 103. This preload is the amount of force with which the pipe 105 is held from the main support 103. A preload ensures that the pipe 105 is held firmly in the main support 103.
Fig. 75 is a side view of a pipe 105 positioned for attachment to a main support 103, according to an embodiment. Barrel 105 can be attached to main support 103 by pressing down on the barrel lock 113 (as indicated by the down arrow) in order to move the swing wedge 8253 to the left in such a way that the swing wedge 8253 can receive the pin 8254. Barrel lock 113 and oscillating wedge 8253 can rotate against spring tension about pivot pin 7581 (as indicated by the curved arrow counterclockwise) when level 113 is pressed down.
After the barrel latch 113 is pressed, the barrel 105 can generally move upwards (as indicated by the up arrows). The ramp 8252 can act as a guide for the proximal end of the pipe 105 during installation of the pipe 105. The distal end of the pipe 105, for example, the extension of the pipe 8606, can be seated before the pin 8254 is received by the oscillating wedge 8253. Fig. 76 is a side view of a pipe 105 attached to a main support 103, according to an embodiment.
Once the pipe 105 is inside the rear V block 8081 and the front V block 8082 and 15 "once the flange 8087 of the pipe extension 8088 is inside the groove 8086 of the rear V block 8081, then the pipe lock 113 can be released in such a way that spring tension causes the oscillating wedge 8253 to engage pin 8254 in order to attach the pipe 105 to the main support 103. Figure 77 is a cross-sectional side view of the pipe 105 and main support 103 made to the along line 77 of figure 76, according to an embodiment.
The rear block V 8081 makes contact with the pipe 105 in an arc of approximately 120º in the top portion of the pipe 105. Figure 78 is a cross sectional side view showing the pipe 105 and the main support 103 of figure 77 exploded from each other , according to one modality.
Fig. 79 is a cross-sectional side view of pipe 105, main support 103, oscillating wedge 8253, and tensioner 8083 made along line 79 of Fig. 76, according to an embodiment.
Once pipe 105 has been attached to main support 103, tensioner 8083 maintains a preload that secures pipe 105 securely to main support 103. For example, tensioner 8083 can provide a preload of approximately 700 pounds ( 318 Kg) that holds the pipe 105 in the main support 103.
With particular reference to figures 77-82, tensioner 8083 may have a fork 7901 that extends downward from pin 8254. In response to pin 8254 being pulled upward by oscillating wedge 8253, fork 7901 can pull upward to compress washers spring clip 7902 when pipe 105 is attached to main bracket 103. Compressed spring washers 7902 push up a threaded collar or flange 7903. Threaded flange 7903 has a screw 7904 threaded through it and making contact with pipe 105. O screw 7904 rests on pipe 105 and applies a preload generated by compressed spring washers 7902 on pipe 105. The amount of preload is adjustable by turning screw 7904.
A 7921 screw can attach the front cable 106 to the tensioner 8083 and thus to the firearm. Screw 7921 can be threaded into an extension 7922 that is suspended on tensioner 8083.
Figure 83 shows in which of the three firearms several different resources can be found. For example, all auto open bolt operation can be found on machine gun 100 and rifle / machine gun 8000, shown in line one of the graph. Features of the machine gun 100, the semi-automatic rifle 1000 and the machine gun 8000 can be used in both, and in other firearms. Such features can be used alone, or in any desired combination, on any firearm. For example, the measured gas orifice 7602 and extractor 9100 can be used in other firearms, such as the M16 and MA4.

A firearm cycles due to arming or firing so that a new cartridge is removed from its storage. 9701 An extractor claw can ramp up over a cartridge rim and an extractor stop pin limits the extractor's movement backwards as the 9702 cartridge is placed in the chamber.
The two springs apply force to the extractor as the cartridge is extracted after the firearm is fired. 9703 i 101/107 7002 - 7001 7001 7002 FIG, 70
