    Improvements in the means of controlling selectors or oscillating jacks of knitting, knitting machines, and in particular hosiery machines and the like, to increase the speed, limit the irregular movements of the jacks and the heating, which include a cam for selectively raise the jacks in relation to the selection imposed by the thrust levers acting on the selection heels of the jacks in the pick-up area of a fed wire, characterized in that in correspondence of the thread pickup, a cam is provided which it has a lower profile parallel to the trajectory of a heel of the jacks that have not been raised, to prevent irregular or uncontrolled movements of said jacks not raised.

    2, a mechanism according to claim 1, characterized in that the profiled lever is mounted so as to be in contact with a protruding helium of the selector.
    3. The mechanism according to claim 1, characterized in that one shoulder of the profiled lever is spring-loaded and pivotally connected with the bed of the machine, and the other shoulder has a bevel.
    4. The mechanism according to claim 1, distinguished by the fact that the profiled lever is installed with the possibility of contact with the self-stopping machine by means of a microswitch,
    The invention relates to knitwear engineering, in particular, to mechanisms for selecting selectors of hall machines. 4 The known mechanism for selecting selectors of stocking machines, including a cam for raising selectors, thrust levers and two projections for limiting the vertical movement of selectors and heating them, is known. Disadvantages of the known mechanism are the occurrence of heat due to friction between the chuvods and side walls with increasing machine speed, as well as the spontaneous movement of the selectors. The purpose of the invention is to increase the productivity of the machine and prevent the uneven movement of the selectors and their heating. The goal is achieved by the fact that the mechanism has an additionally profiled lever mounted at the level of the upper protrusion, while the axis of the profiled lever is located parallel to the line of the protrusions of the selector lever. In addition, the profiled lever is installed with the possibility of contact with the projecting helix selector. In this case, one shoulder is profiled, the lever is spring-loaded and pivotally connected to the machine bed, and the other shoulder has a bevel. In addition to this, the profiled lever is mounted with the possibility of contact with the self-stopping machine via a microswitch. In Fig. 1 shows the proposed mechanism, the overall Vied in section; FIG. 2 is a section A-A in FIG. 1; Fig. 3 is a section B-B in Fig. 1; The selection mechanism of the selectors contains a needle cylinder 1 in which slots the needles are located, and from the bottom of the needles there are selectors 2. Each selector 2 has projections 3 and 4 to limit the vertical movement of the selectors and projections 5, which can be selectively moved and come into contact with the stop levers 6. The upper 3 and lower 4 protrusions of the selectors 2 interact with the upper 7 and lower 8 guides. The upper direction of the switch 7 has a channel 9, corresponding to the zone of the selector lift and, therefore, the path of movement of the needle flow 1.0 at the time of laying the thread. When the needles move in the direction of the arrow 11, the needle needles fall under the action of the lowering of the wedge 12 and the restrictive wedge 13. For raising the selectors 2, there is a cam 14, interacting with the lower projections 4, Each selector 2 can perform rocking movements at its point 15, which is the diametrical plane for the needle cylinder 1. .. The selectors 2 are displaced by their lower protrusions 4 outwards relative to the base of the channels by means of a cam 16 acting on the inner edge of the selector. The action of the cam 16 is stopped in front of the levers 6 in order to allow the levers to selectively interact with the projections 5 in order to move the needle cylinder 1 into the channel. Those selectors that were not raised, while the selectors (which should be raised) are held at their ends, projecting so so that they can interact with the protrusion 4 and the cam 14 and thereby raise, raising the needles 10 to the trajectory of movement. Raised selectors 2. remain in position between the profiles of cam 14 and channel 9, while selectors 2 that have not been raised by cam 14 remain free in their channels and can move in the cavity bounded by channel 9. To prevent uneven lifting of selectors and increased heating at high speeds, the mechanism additionally has a profiled lever 17 mounted at the level of the upper protrusion 3. The axis 18 of the profiled lever 17 is located parallel to the line of the protrusions 5 of the selectors.
    The profiled lever 17 does not interfere with the selective lifting of the selectors, which must raise the needles, since the protrusions 3 pass over the end 19 of the profiled lever 17, and the upper surface of the end 19 has a corresponding bevel. At this end there is also a radial bevel 20, which serves to intercept the projections 3 of the selectors 2, which are slightly raised instead of evenly
    go down.
     The profiled lever 17 is fixed on the axis 18 with the possibility of oscillation and is loaded with a spring 21 in the direction of the arrow 22, i.e. in the direction of the needle 15
    cylinder 1, BEFORE the stopper 23. The stopper 23 usually establishes a shaped lever 17 regarding its support 24, which is affected by the spring 21.
    If there is a protrusion 3, which interacts with the bevel 20, the profiled lever 17 rises in the direction opposite to the arrow 22, which eliminates half the width, for example, when interacting with the microtransmitter 25: the protrusion 3 of the selector 2, which was not prdnt, interacts with the lower profile of the lever 17 and accidental lifting of the protrusion does not occur.
