Abstract

FIELD: weapons and ammunition.

SUBSTANCE: gun has cartridge belt drive, portable belt box and interconnecting sleeve made of resilient material or fabric coated with antifriction coating. Besides, the gun can have the sleeve consisting of several articulated truncated pyramids or cones spaced apart by securing to outer fabric or resilient sleeved at the points of their maximum cross-section or by hinges with increased play at the pints of their joint. Articulated sleeve has outlet pipe to be fitted in the gun with one or two spring-loaded plates to lock the belt against backstroke and incorporates to latch for fast attachment to the gun.

Description

The invention relates to small arms - machine guns, submachine guns, light machine guns.

Known automatic, see US Pat. No. 2399004, in which the store separates after it is empty, and the shutter rises to the shutter lag. But if the cartridges run out at a tense moment of the battle, then there may not be enough time to install a new store. To reduce this time, soldiers often tie the two stores with masking tape, which is not the best solution.

The domestic and foreign experience of World War II shows that soldiers of all armies preferred more complex and heavier disk stores to box-type stores because they had more cartridges (71 cartridges were placed in the PPSh magazine and 100 cartridges in the Thompson disk store). Apparently, the soldier’s experience suggests that the most important thing in battle is not to be left without ammunition at the right time.

It would seem that you can provide the machine with tape power. However, the experience of operating light machine guns with a tape feed from a hinged box shows that the number of rounds in such a box is also limited by reasonable limits, and the maneuverability of an infantryman with such a box drops sharply. In addition, changing the tape or attaching the next piece of tape took too much time - much more than changing the store.

The objective and technical result of the invention is the supply of portable weapons with cartridges in a tape way.

OPTION 1. Modern materials allow this idea to be implemented. This weapon has a tape drive mechanism, a wearable box for tape (hereinafter referred to as the “ribbon box”) and a sleeve connecting them from an elastic material or fabric coated with an antifriction layer from the inside.

As an elastic material for the sleeve, you can use a knitted weave fabric, preferably heat-resistant enough so that it does not melt in contact with a heated barrel, for example, wool, cotton, linen, or artificial fibers, such as polyester fiber, or polyurethane tape.

A fluoroplastic film can be used as an antifriction coating.

The features of the relative position of the ribbon box and the weapon are such that the receiver neck of the weapon is located from the bottom or bottom-left (for right-handed people), and the supply neck of the ribbon box is located to the right, or top, or right-top.

This weapon works like this: the ribbon box is hung in a convenient place on the shooter's body, for example, on the left side of the belt, and when fired, the cartridges are continuously fed into the weapon.

OPTION 2. However, kinks of the sleeve are possible, which can lead to a delay in firing. Therefore, it is better to use another method - instead of a fabric sleeve, this weapon has a sleeve consisting of articulated truncated pyramids or cones that distance themselves by attaching to an external fabric or elastic sleeve at their largest cross-sections or distance using hinges with a large backlash located in places of their joints.

For the convenience of refueling the tape in the weapon, the sleeve has an outlet pipe designed for quick insertion into the weapon, has one or two spring-loaded plates in this pipe, directed along the tape and preventing the tape from moving backward (like a “check valve”), and has It has a latch for quick attachment to weapons.

Figure 1 shows such a sleeve without an outer fabric sleeve. It consists of identical truncated rectangular pyramids 1 having noticeably narrowing large sides (upper and lower on the sketch) and almost parallel small sides (front and back on the sketch). Of course, the size of the pyramids is such that the curb tape runs freely with a margin in them. Cartridge 2 is shown in the pyramid.

Figure 2 shows such an articulated sleeve in which the pyramids 1 are spaced by fastening to the outer fabric sleeve 3 (conventionally shown by a thickening). If the pyramids are made of thermoplastic, for example polypropylene, then fixing the sleeve, for example, from wool, can occur by melting the pyramid directly through the fabric at the site of the largest cross-section of the pyramid. The fabric adheres to the molten material of the pyramid and they are fixed relative to each other.

Figure 3 shows the spacing of two pyramids using hinges with a large backlash (one hinge is shown). It is a relatively large hole 4 at the thick end of the pyramid, which includes a relatively small pin 5 at the thin end of another pyramid. The hole may be round, as in figure 3, and may be square, oval, oblong or radial, located across the axis of the pyramid. Such a hinge allows limited bending of the sleeve in any plane and allows torsion of the sleeve (that is, it takes the form of a propeller). Such a sleeve is functional without an external fabric sleeve, but the latter in this case plays the role of protection from dirt.

Instead of pyramids, cones can be used, or rather combined surfaces consisting of two flat plates (large surfaces) and two rounded conical surfaces mating with them.

The sleeve according to option 2 will provide uninterrupted power to the weapon at any of the three main positions of the weapon - at the belt, at the shoulder, and lying down.

In addition to the understandable main advantage - the ability to not lose the combat efficiency of a weapon during the battle, this weapon has another advantage - since there is no change of stores, possibly sometimes contaminated, there is no unnecessary opportunity to introduce pollution into the weapon. That is, the dirt resistance of the weapon increases. There is also a third advantage - the mass of weapons in the hands, involved, for example, when turning the weapon from left to right, turns out to be less, that is, the shooter will maneuver the weapon faster, responding to the rapidly changing battle environment.
