Description

The present invention relates to an automatic pistol with a fixed barrel and a non-engaging bolt.

In the schematic drawing of FIG. 1 shows a partial longitudinal section of the gun; and FIG. 2 and 3 parts of the device, fuse and switch gun in longitudinal sections.

The proposed gun allows it to be fired either by machine gun fire or single when for production — each shot requires a separate trigger pull. When it is pressed, the end face T of the trigger earring N. leans backwards. The end face t moves along the platform n (Fig. 1) and the corner shoulder lifts the tail of the two shoulders and whispers it. This lift takes place until the second shoulder whisper, representing the stop for the platoon, is flush with the frame; at that moment the striker's tail platoon of the striker breaks off from the stop whispering. Simultaneously with the maximum tail lifted whispered, butt from the trigger

the earrings will reach the extreme position on the platform n and tear it into the recess of it. After the shot, the sear cannot interfere with the movement of the carriage back and, as the latter moves, the drummer’s tail will hook again to the shearer's rest point and coax the spring. To make the next shot, it is necessary to allow the spring p (FIG. 1) to put the trigger earring and hook into place, i.e., to make the end face t in its place on the platform n; for this you need to release the index finger that pressed the trigger, then the spring p ot no earring to its original position. From what has been said, it is clear that the repetition of shots is possible only by pressing a finger on the trigger each time separately.

To fire machine gun fire, the pistol can be equipped with a fire switch (Fig. 2 and 3). When the end of the switch h is raised so that the switch rests on the upper bevel of the socket in which it sits

(Fig. 2), the shooting is done in the usual order, as described above, since then the whisper's tail will rise and the support will catch on the striker striker. If the end of the switch h is set to the position shown in FIG. 3 then, as can be seen from the drawing, the tail of the switch will squeeze the tail whispered downwards, and the emphasis of the sear will be flush with the frame. In this case, the fire will be of the type of machine-gun, with the opening of fire produced by pressing a finger on the trigger, and the termination of the fire - release of the hook.

At the same time, the striker's tail P is depleted from the emphasis of the sear when the gun carriage has not reached the full 2 mm place, and the end of the striker must pass a distance of 20 mm, i.e. the path of the impactor, counting from the critical moment, is 10 times the remaining path of the carriage (or gate). It is quite obvious that due to such a difference in the striker and carriage paths, the shot will occur only a few moments after the shutter is completely closed. Shifting the switch is done by pressing the button A with the thumb of the right hand and moving it.

As already mentioned, the switch can also be in the off position, but its end can be made so that even when it is off, it will slightly touch the tail part of the sear, i.e., when the carriage rolls into place, the sear will somewhat decrease and the descent will be somewhat alarming.

Before firing, as in other samples of weapons, it is necessary to move the fuse to fire. The permutation is made by translating the strap g (Fig. 1), conveniently controlled by the thumb of the right hand. When moving the guard down (to itself), the end of it “comes out of the recess in the back of the whisperer, and then a shot is possible when you press the trigger with your finger. G. When the guard is locked, i.e. moved upwards, when the tail enters the backstop of the sear (Fig. 1), the shot is absolutely impossible, since the sear can not move either from the mattress or from other causes and the tail of the striker cannot break from the sear's stop. In order for a shot to happen when the guard is locked - only a serious breakdown is needed. parts, such as the sear or the hammer rod, and since the forces acting in these parts are negligible compared with the cross section of these parts, the possibility of breakage is normally completely completely excluded.

The location of the fuse on the back of the handle is chosen from those considerations so that it is convenient to open it when the pistol is pulled from the holster. The movement for relocation of the fuse can be learned quickly and easily to the degree of unconsciousness, so that no focusing of the arrow on this point is required. Another advantage of this arrangement is the ability to clearly see even when the pistol is raised, the degree of its readiness for firing without lowering the pistol and other procedures.

After placing the fuse on fire, shooting is done in one of the above ways.

At the last shot, the carriage, after rolling it back, remains in its rear end position. This is achieved in the following way: the gauge (Fig. 1), not resting its end against the cartridge, is thrown back and with its other end t sinks into the groove in the body of the bolt. Thanks to this carriage delay, CTpeJioK sees that it no longer has charges and needs to be replaced with a clip. When inserting a new clip, as soon as the top cartridge
