    A rotary hand knife 20 of the type having a pinion-driven ring blade 34 and used for trimming meat, fat, and the like, with an improved pinion cap 58 and a depth-of-cut gauge 47 for use with the knife, and with an improved drive pinion recess 56 and blade-retaining shoe 36. The cap provides a stepped mounting surface 149 for the gauge that forms a passage R for product scrap or slices to pass behind the gauge. The cap also has a lip 154 that blocks entry of product particles into the blade-driving pinion. The gauge has an arcuate portion 47a offset toward the blade from a base portion 47b that abuts the cap and slides axially on the cap surface to adjust the depth of cut. The recess 56 has a flared portion 56a to facilitate egress of product particles that otherwise would be trapped. The shoe 36 has a relieved portion 110a that prevents binding against the knife blade while yet covering the blade teeth.

    and the bottom 17, and the length and thickness of the upper part 16 exceeds the length and thickness of the lower part 17. The upper part has on the outer surface flat sections 18 parallel to the axis of symmetry of the blade.
    In addition, the lower part 17 is directly adjacent to the blade 9, and the upper part 16 is located in the axial direction further from the blade, while the outer edge of the lower
    parts of the wall are provided with a sponge 19 bent outward in the direction of the gear location, which serves to block the groove 8 between the housing and the handle 5, and is adjacent directly to the blade of the knife, and the base 14 of the depth of cut limiter is installed with contact its lower part of the gap R to remove waste of the cut part of the raw material. The wall of the cover 6 of the gear 5 on the handle side can be cylindrical and mounted with the possibility of interaction with the arcuate 5 section 3 of the handle. The recess 4 in the arcuate section 3 may be provided with a hole 20 facing the toothed end 11 of the annular blade 9, and on one side of the gear has a greater width than the other.
    The housing 7 and the blade 9 are small compared with their axial diameters
    -long. The blade is made in the shape of a truncated cone having a tooth
    | 21 on the axial axle 22 of larger diameter, adjacent to the body, and the cutting edge 12, formed on the other, smaller axial end 23, protruding axially from the main plane of the body 7
    L 1rbased front side of the knife.
    The mechanically driven pinion gear 5 placed in the handle is engaged with the teeth 21 and is intended to rotate the blade relative to the body. The gear is rotated by a rotating cable 24 having a drive

    -I external electric motor (not shown). L according to another variant the gear can be driven by an air motor and a gear inside the tubular element.
    An annular cut-off depth gauge is attached to the handle with the ability to adjust by means of flat head screws 15 for adjusting the thickness of the octagonal pieces by limiting the depth at which the blade can be inserted into the product.
    The handle (FIG. 2) is a metal casting, with the tubular element 1 having a central recess (opening) 25. At the arc-shaped end of the handle there is a sleeve 26 with a flange. The hub gear 5 is rotatably mounted in the sleeve, recessed into the recess 4 in the surface of the arcuate section 3 of the handle.
    A plastic cap 6 is attached to the handle by means of flat-head screws 15, covering the pinion gear 5. On the tubular element 1, a flexible sheath 28 of cable 24 is placed and secured by means of a screw 27. Inside the sheath 28 is mounted for rotation a central cable 29 attached to the pinion gear 5 to bring it in rotation with the rotation of the center cable by an electric motor (not shown). In order to provide lubrication, the gear is provided on the handle with a grease reservoir 30 communicating with a recess in which the gear is housed. The recess 4 for the pinion gear 5 extends onto the surface 31 of the handle, the pinion gear passes through the hole 20 and engages in the gear teeth of the blade. As shown in Fig. 10, a portion of the recess 4 is made (in section 32) semi-cylindrical, and the remainder consists of an outwardly extending section 33 on one side of the opening 20 and a rectilinear section 34 perpendicular to the surface 31. As shown in FIG. 10, the outwardly extending portion 33 extends from the place (or slightly above it) at the intersection of the periphery of the recess 4 with an imaginary plane 35 parallel to the flat surface 31 and passing

    through the central axis of the central depressing recess 25. The expanding section is formed by a flat wall tangential to the cylindrical part of the wall of the recess and extending at an angle of 75 ° to the surface 31. The extending section is located on the back side of the recess 4 relative to the blade placement direction.
    In addition, in the arcuate section 3 there are two (one on each opposite side of the recess 4) recesses 36, 37 (Fig. 10) extending onto a flat surface 31 in which the screw heads are placed
    38 coming over the surface 31
    coupled with the casing dp fastening it to the handle. These recesses are partially cylindrical, but each of them also has an outwardly extended section on one side.
    39.40, extending from the intersection of the periphery of the corresponding recess with an imaginary plane parallel to the surface 31
    and extending through central apertures 41, 42 with an inner ribon for screws 38. Each of the extended portions 39, 40 is formed by a wall, tangential to the partially cylindrical wall of the recess and extending at an angle of 75 ° to the surface 31. on the back with respect to i
    the direction of movement of the blade to the side near each recess 39,
    40, With the design of the recesses described above, the particles of the product introduced
    k in the recesses behind the blade will pass around the wall of each recess and, going out through a more open path created by the expanding sections, as a result of the rotation of 5 the blades are carried away, and will not be packed into the recesses and, having accumulated there, pinch the blade.
    The cover 6 of the gear 5 has, as shown in FIGS. 2, 4, 5, 7–9, a flat stepped front surface and a cylindrical convex rear surface that overlaps the gear and coincides in curvature with a concave arc-shaped section 3 of the handle.
    As shown in Figs. 6-8, due to the greater thickness of the cover 6 behind the part 16, its width in the direction of movement of the blade is greater than the width of part 17. (the ends of part 17

    side edges A3, 44 are formed, where the cylindrical rear surface converges with a flat front surface. Since the back surface is in contact with the arcuate section 3 of the handle, the edges 43, 44 are flush with the end surface and serve to intercept, deflect and prevent entry into the recess for gear gear, tendons or other particles of the product carried by the blade. The bottom edge 45 is curved along its length in the plane of part 17 and has a beveled surface 46 running backwards and upwards at an angle comparable to the angle of inclination of the upper surface 47 of the blade (in FIG. 5) and located close to the surface of the blade to prevent the passage of the transferred blade. particles under the cover into the space between the teeth 21 or around the teeth of the pinion gear. On one side of the lid of the upper surface of the beveled surface, the sponge 19 moves back from the rear surface in its immediate vicinity. As shown in FIGS. 5, 8, 9, the sponge 19 has a flat upper surface 48 in a plane perpendicular to the front surface part 17 and located surface 49, and the arcuate beveled surface 50, extending between surfaces 46 and 48 and ending with a curved end 51, closely matching gear 5 along the curvature. Surface 48 is in direct contact with the surface 31 of the groove 8, and The surface 50 is in close proximity to the beveled surface 52 of the inner diameter of the housing 7. Thus, the sponge fills and blocks the remaining part of the groove 8 not occupied by the casing near one side of the gear. The relationship of the cover 6 and the sponge 19 with the gear is shown in Figures 4 and 6. Figure 4-5 shows how the sponge prevents the blade from moving the product particles into the gear placement area on one side of it. Since the sponge is only on one side of the cover, there are no obstacles on the opposite side of the gear in the wedge-shaped groove 8 in the handle near the housing 7. This is best shown in FIG. 4, where it is visible

    an expanding passage P behind the cover allowing the particles that enter the gear area on the opposite side to exit. As shown in FIGS. 6-8, the thickness of the sponge 19, which exceeds the thickness of the adjacent portions of the lid, reaches the surface portion 17 in front of the sponge, resulting in an edge portion 53 behind the side edge portion 54 formed where the arcuate back surface is connected to Part 17 of the front face is different. The hem portion 53 (FIG. 9) is blunt, and the hem portion 54 is as sharp as the hem 55.
    The limiter is an annular structure with an arcuate element 13 for adjusting the depth of cut and a base 14, with which the limiter is installed in the desired position on the surface of the gear cover and secured by hand-tightening screws 15. In the dear case, the limiter, as shown in Figures 1 and 3, is not a complete ring, but is a part with an arcuate element 13, which cantileverly departs from the support part by a distance of just 1 more than 180, so that there is a gap between its end 56 and the supporting part. The radius of curvature of the arcuate element 13 on the outer surface is preferably slightly smaller than the radius of the cutting edge of the blade. In cross section, the element 13 has a rectangular profile with rounded corners. As shown in Fig. 2, the arcuate portion 57 is displaced in the direction of the axis of the blade from the base 14 closer to the blade. Thus, the product-contacting surface 58, limiting the depth of cut, is closer to the blade than the edge-facing surface 59 of base 14 parallel to the blade. Between the surfaces 59 and 58 passes a transitional section 60, arched in plan and inclined in the vertical projection.
    The base 14 has a flat mounting surface 61 adjacent to the surface 16 of the cover 6. As shown in FIG. 1, the length of the surface 61 is the same as the length of the cover 16, but as shown in FIG. 2,
    its height is somewhat greater. The grooves 62, the diameter of the rip of the diameter of the threaded rods of the thumb screws 15, and a little more than 1 height, allow the movement of the stopper relative to the cover in the direction of the blade axis to change the gap 63 between the blade and the stopper. This movement is provided by loosening the thumbscrews, each of which has a clamping surface 64 acting on the support part of the stopper, and by rotating the thumb adjustment BINT 65 and 66 installed in the arcuate part of the handle. The pins 65 and 66 are screwed into the threaded holes extending in the direction of the blade axis and have large circular disc-shaped flanges 67, 68, some of which enter the corresponding groove 69, 70 in the outer peripheral surface of the base 14 and which move the stopper in the axial direction when rotating the screws. When the limiter is fully raised, the surface 59 is flush with the surface 49 of the gear cover and sufficiently distanced from the blade to prevent the pieces of the product being cut off past the bearing part of the limiter from being cut off. When the stopper is positioned close to the blade, as shown in FIGS. 2 and 5, the lowered position of the surface portion 17, creating a gap between the protruding surface 6 of the stopper and the cap portion 17, provides a passage for material that would otherwise entered the groove for the gear behind the cover 6.
    One end 71 of the base 14 of the stopper, facing the railing of the blade, has an inclined surface 72, furthest from the blade at the end and tilted to the blade inward from the end,. in the direction of rotation of the blade. the surface 72 deflects the pieces of the product carried by the blade and forces them to pass between the limiter surface 59 and the blade rather than accumulate at the support part of the limiter.
    In the preferred embodiment, both the stopper and the gear cover are made of nylon. When using a knife without limiter, use shorter screws.
    The hinge 73 of the knife (fig. 1-3) consists of a threaded sleeve 74 provided with an attached threaded block 75 to one end, a screw 77 with a threaded ring 77, and a spring 78, surrounding the horn, and acting between the ring and the handle. If you press on the ring 77 for 5
    the block and sleeve move in the axial direction, overcoming the resistance of the spring 78, with the result that the block moves away from the front
    0 surface 79 of the handle and part of the block near the axis of rotation extends beyond the plane of the blade of the knife, which allows the block to rotate around the axis of the screw 76

    to remove the blade,
    The far end of the pads 75 is fixed by means of a locking screw 80 in the front end of section 3, which interacts with the shaped groove 81
    in the block. This groove is elongated in a direction that allows it to be rotated a short distance towards the blade and back while the screw is in the groove.
    A handwheel (adjustment head) 03 with a rod 84 is screwed into the threaded hole 82 of section 3. The handwheel acts as a stop for pad 75, providing the ability to adjust
    the pads are relative to the blade and held in the regen position. A spring 85, surrounding the rod 84 and acting on the handwheel and section 3, holds the handwheel in
    adjusted position. The periphery of the handwheel is made smooth to prevent accidental adjustment when the operator’s finger moves around the periphery of the handwheel during
    use a knife. For relief
    adjustment in the end of the fly-pin is made slot 86.
    Case 7 of the blade is made round and in different areas has different
    cross sectional profiles. The heads of the two mounting screws 38 abut on the flat sections on the inner periphery of the casing, and the screws are screwed into the threaded holes 41, 42 in the arc section 3 of the handle. The housing 7 has a notch 87 (pin 2, 4) for the gear 5, allowing it to pass through the plane of the casing and interact with the serrated edge of the blade. The housing has on its front side a radial surface 88 (Fig. 4), on which the blade rests and on which it slides during rotation. The radial surface has a circumferentially variable width In the part of the body that passes behind the arcuate section 3, a peripheral bead 89 passes around the radial surface 88. Its circumference around the casing does not prevent 180 °. The ends 90, 91 of the peripheral bead are shown in FIG. 3 and are preferably diametrically opposed to each other.
    The blade 9 is mounted so that its jagged end 11 rests on the radial surface 88 of the housing, and is partially covered by the peripheral edge 89. As shown in FIG. 3, the retaining pad 75 is adjacent to the radial surface 88 of the housing and to the outer surface 92 of the truncated cone blade.
    The retaining block 75 is in the form of an arcuate plate corresponding to the front surface 79 of the handle and adjacent to it. The inner edge 93 of the pads is beveled in accordance with the type with the blade surface 92 and has the same radius of curvature, so that when its center of curvature coincides with the center of curvature of the blade, it is adjacent to the specified blade section. With this position, the locking screw 80 with the head is located in the shaped groove 81. The extended portion of the slot groove is larger than the heads of the locking screw 80, and the narrower portion is intended to accommodate the screw stem 80 when the shoe is in contact with the blade. In this position, the screw head prevents the pad from moving away from the front surface 79 of the handle.
    The slightly indented edge portion 94 of the roach prevents pinching on the blade at the pivotally attached end 95, but the depth of the recess is made minimal to ensure that the blade teeth are completely covered with a pad on

    a section 94 for preventing the teeth from contacting with the product being cut and for them to transfer the product particles into the spaces between the teeth of the drive gear and into the recess for it. Section 94 is concentric to edge 93, but its radius of curvature is slightly larger (preferably not more than 0.05 inches).
    At the end 95, a boss 96 is provided to accommodate the sleeve 74. The pad at the end 95 ends with an edge 97 extending in the direction of the radius of curvature of the pad, and a small radius 98 is rounded at the point of its connection with the inner edge portion 94 of the pad, so that the edge 97 of the pad is located in close proximity to the hull board 89 and closes the blade teeth so that at the point of rounding off the teeth are open for no more than a tooth. At the opposite end, the block is also located in close proximity to the hull side and there, too, the teeth are open no more than the width of the tooth. Such a measure prevents the teeth from catching the blade of the product particles and transferring it to the drive mechanism by the blade. Pressing the ring 77 in the swivel 73 ensures the pad departs from the handle surface 79, thereby allowing the pad to move over the head of the locking screw 80 and the pad section at the rounding 98 from the blade (i.e., from its plane), thereby rounding 98 and the blade will not collide with each other when turning the pad in a direction away from the arcuate portion 3 and moving rounding 98 toward the blade.
    The outer edge 99 of the pad 75 has a tide 100 giving a wider portion of the pad extending beyond the arcuate portion 3 and engaging the handwheel 83. When the screw 80 enters the figure groove 81, the handwheel is adjusted to hold the pad by positioning the narrower portion slot under the screw head. In addition, the handwheel presses the inner beveled edge of the pad to the blade, providing a tight setting of the blade over the body side 89. Choosing a gap between the blade and the hull edge by adjusting the position
    handwheel, apply proper force to allow the blades to rotate relative to the body.
    Hand knife work as follows.
    To remove the blade from the body, rotate the handwheel 83 in the direction of its withdrawal from the pad 75, which allows the pad to rotate around the axis of the swivel 73 and align the screw head 80 with the expanded part of the groove 81. Move the pad 75 in the direction from the front surface of the handle to the screw 80 and then turn it, retraction from the blade. Thereafter, the blade can be extended out from under the peripheral bead 89 in the direction of the tubular element 1 and pulled upwards from the body and the handle. The new blade is inserted in reverse order. Thus, the operator can easily replace the blade without the use of tools or complex adjustments, which contributes to frequent replacement of the blades and thereby provides increased reliability and ease of use, as well as high cutting performance.
