Description

Automatic weapons are known with a barrel moving forward from the action of cutting a bullet into grooves; There are also no novelty cartridge tapes with hooks. In the proposed automatic rifle, the cartridges during firing are not pushed out of the belt, but remain connected to it. For the passage of the tape are cutouts in the receiver, in which the tape enters when running onto the cartridge.

In FIG. 1 shows a longitudinal section of a rifle; FIG. 2 is a side view of it; FIG. 3 shows a section along the line AB in FIG. one; FIG. 4 is a section along the line of the LED in FIG. 2; FIG. 5 is a top view of the cartridge belt.

Butt 7, barrel box 2 and stop 3 (figs. 1 and 2) are made entirely of steel. The stock serves for ease of firing, and the trigger mechanism and the tape feeder are placed in the receiver. In the stop 3 there is a socket 4, into which, at the connection with the Jacket, a connecting clip of the case enters, and an opening 5 (Fig. 3) for fastening with a connecting screw. The barrel box 2 has two grooves in length: the tape feeder is placed in the first one, the trigger lever, the trigger spring and the trigger hook are placed in the second one. At the bottom of the receiver is attached knob 8 with trigger guard 9. Circle

the rim of the receiver has a side JO, which, when connected to the casing, enters the groove of the casing M.

The barrel inside is the same as the 3-line rifle. At the base of the chamber there is a boring with a transverse slot for placing the cartridge together with the tape, and at the bottom there is a small cutout where the ejector head is marked.

To increase the cooling surface, the barrel surface is ribbed or a special radiator is put on it.

Tape 6 with cartridges (Fig. 5) is composed of individual links of twenty five rounds each. The link is made of an elastic metal in the form of a tape 6, on which metal tubes are fixed, into which the cartridge is inserted up to the stop in the cylinder head. In each tube there is a cutout for placing the head of the ejector. The final two tubes of the link have half the normal height and are located on both sides of the plane passing through the middle of the belt, so that after patching the cartridge through these two extreme tubes of two links, one tape is obtained, or by connecting the ends of one link, a ribbon ring is obtained. Such a single link ring represents the normal armament of a rifle for all types of bo.
