Description

The invention relates to automatic weapons with a barrel moving forward and magazine-powered.

A distinctive feature of the present invention is that the weapon barrel is provided with a feeder, which, when the barrel pressure is in the rear position, moves the cartridge from the magazine back to the rammer, which feeds the cartridge to the level of the axis of the barrel bore.

The essence of the invention is illustrated in schematic drawings.

The drawings show: in FIG. 1 - a general view of the proposed. Shop; in fig. 2 is a view along the arrow “L. the shop shown in FIG. 1 in the case of a single version, and in FIG. 3 - in the case of a double version; in fig. 4 - position of the parts of the gun before the shot; in fig. 5 is a sectional view of the device shown in FIG. 4 bb; FIG. 6 is a view of the device shown in FIG. 4 on p. / 7; in fig. 7-position of the parts of the gun after the shot when moving the barrel forward; in fig. 8 - the position of the parts of the guns when moving the barrel back; in fig. 9 is a diagram of the cartridge, in the case of the use of a double-row magazine.

As can be seen from FIG. 1 and 2 for the proposed automatic weapon; a conventional box type insert box magazine, differing only in that a groove a is made in the upper part of its front wall. Top receiver store is equipped with curved tabs in. which keep the cartridge from moving upwards.

As can be seen from FIG. 4 and 5, the bottom of the barrel is provided with a feeder / located so that one cartridge is placed along its length between its rear end and the magazine cut of the barrel.

As can be seen in the drawing of FIG. 7, as the barrel moves forward, the feeder comes off the magazine receiver and the next cartridge. With the force of the magazine springs, it rises up and presses against the legs.

No. 69577-2Pri the return movement of the barrel (see Fig. 8) the feeder, the passage through the groove of the magazine, pushes the next cartridge back. This cartridge is placed on the rammer 2.

 When the barrel moves forward, the chamber will come off the arrow sleeve, held in place by the paws of the combat larva 3, the exciting sleeve sleeve. While the stump of the barrel is not completely off the cartridge located in the rammer, the latter remains in its place, holding the stump of the barrel from the upward movement of the lower part and the forward stanchion from the forward movement, grabbing the sleeve for the collar.

Upon further movement of the barrel forward, the rammer 2 begins to raise the next cartridge upward, until the axes of the cartridge and the chamber become coincident.

In this case, the collar of the cartridge case enters the paws of the combat larva 3 and the bottom of the sleeve begins to flatten the teeth of the latch 4, which is chamfered on the feed side.

When the cartridge reaches the chamber axis, the latch, under the action of its spring, will lock the cartridge in the ready position for feeding into the naipOHHHK.

The action of the system in the case of the use of a two-store magazine will differ from that described only in that when the cartridge moves from the magazine back, the cartridge will make not only a longitudinal movement, but also some lateral movement until its axis coincides with the axis of the barrel.

This is accomplished by lateral bevels of the rammer nest, which is clearly seen from FIG. 9.

Subject invention

An automatic weapon with a forward-moving barrel and magazine-powered food, is distinguished by the fact that the barrel is equipped with a feeder, which, when the barrel moves to the rear position, moves the cartridge from the magazine back to the rammer, which feeds the cartridge to the level of the barrel bore axis.
