Description

The proposed adaptation to the magazine rifle for firing from it by revolving (pistol) cartridges consists of a rifle box inserted into a barrel, instead of a shutter, the body of the device and a special magazine feeding the cartridges with two effective feeders. R

In FIG. 1 shows a section along the line AB of FIG. four; FIG. 2 a section along the line CD of FIG. five; FIG. 3 is a top view of the device; FIG. 4 view from the back; FIG. 5 is a section through the EF fig. 2; FIG. 6 is a section along the line GH of FIG. one; FIG. 7 is a longitudinal section of a magazine box with a magazine inserted into it; FIG. 8 - device assembled from the butt side; FIG. 9- the same, from the side of the trunk; FIG. 10 is a view of the upper part entering the store box; FIG. 11 is a top view of the upper part, with a cartridge, a bolt ready for feeding; FIG. . 12-laying cartridges with feeder.

The proposed fixture (Figs. 1-4) consists of a body / specially inserted instead of the usual shutter of a sector store into a store box (Fig. 7).

The housing 7 is configured at the same time as the shutter of a rifle and barrel chamber and contains a single piston 2, supported by the spring 3 by the hammer 4; special chamber

J8 for a revolving (pistol) cartridge and notches: 20 for feeding cartridges from the magazine and 2 / for removing the sleeves; the joint action of all these parts serves to a-vsmaticheskiy shooting on the principle of weapons with a free gate. Drummer 4 is equipped with a sinker 5 with a cog-stopper 6. To hold the spring 3, the butt plate of the bolt has a nut 7.

The shutter has a latch 8 turning on the axis Y, with a spring 9; for longitudinal movement of the latch 8 serves groove 22.

For the purpose of extracting the liner, a reflector // (FIG. 5) and extractor / 2 were used. The repulsion of the sinker 5 is carried out by a spring 7J of two screws fastened to the gate with a cog f4. A washer / 5 serves to compress the bolt body pipe.

The device is equipped with lugs / b, included in the breech section of the screw assembly, and an external support / 7. The magazine box (Figs. 7-12) is equipped with supplies 25 and 26. The first one, under the action of the spring 27, supplies the cartridges to the transition from a double chess arrangement to a single one, and the second one, under the action of the spring 28, supplies them to the cartridge adaptation. The magazine box (clip) is made of two cheeks 2 and 30, riveted together along the edges.

The spring ends 31 (Fg. 8, § and 1i) of the cheeks 29 and 30 keep the cartridge from falling.

Zar dka and the discharge of the store box is produced by T1K | as in the Browning revolver holder and other similar systems. At the time of the complete discharge of the cage, the spring 28, which is stretching, is in a non-loaded condition. The upper end of it is fixed, and the lower end is attached to the eye of the feeder 25 motors and moves it up to the point of transition from two rows of cartridges to one; thereafter, the feeder 26 begins to move, pushed by the force of the springs 27 and delivering the remainder of the cartridges. When charging, the spring 27 is first compressed, the feeder 26 enters the inside of the feeder 25, BEFORE it stops at the bottom. After Egoy, with further charging, the feeder 25 begins to move, stretching the spring stronger than the spring 27. The holder, when fully charged, has forty patrons.

The proposed fixture is inserted in place of the normal shutter of the rifle with the same hand movements as for the shutter.

After the device is installed in the rifle, the magazine-magazine with the revolving Nagan cartridges in the quantity of forty pieces is laid. The clip is inserted from the bottom into the magazine box of the rifle instead of the five round holes of the magazine from the cartridges, - a plate with springs attached to it to supply the normal sample rounds can remain with the rifle.

The yoke fits snugly into the magazine box of the rifle, the rear and front protrusions 32 and 33, rests on the walls from the butt side and the barrel in the front, and on the sides of the cheeks which are sized to fit the magazine box {Fig. ten).

In the rifle magazine, the clip is replied with a button.

The fixture cannot turn around, along the axis, with the inserted clip, since the spring ends 3t of the arm fit into the notch 2J of the fixture through which Patrone is fed to the gate movement line.

3atsop 2 cocks for shooting

the handle 24 until failure and lowers; during pulling off, the latch 8 drops over the stop used to set the conventional shutter on the cocking; The right index finger is used to pull the trigger. The bolt, moving forward, with its front end on the way pushes the upper cartridge out of the holder and takes it to the chamber, as in the Browning retractor. At the moment of full stop by the bolt to the bottom of the sleeve (when the cartridge is in the chamber), the drummer 4 with a sinker 5 on the other end of it, having an axial free run relative to the gate of 4 mm, continues to move at the speed of the gate and the depth of the strike is adjusted by the weight 5. and stopped by the screw 6. After hitting the capsule, the drummer 4 is spring-loaded / 5 is again set into a combat position.

The rollback is done by applying pressure to the bottom of the liner of the powder gases, giving the gate a certain speed; before the shutter is fully open, the pool has time to leave the bore.

If the trigger of the rifle is kept on the trigger all the time, then automatic shooting will continue until the holder is fully used. Shooting bursts is possible from one or two rounds or more and is adjusted by pressing the trigger of the rifle. The shutter remains always cocked after the cessation of shooting.
