The machine is made of double-sided action with symmetrically located hoppers and sorters, equipped with two tape receivers, and a symmetrical pusher is installed with the possibility of alternately sending cartridges into the belts and is connected to a cantilever guide, in the groove of which the crank roller is located. The proposed machine allows you to speed up the process of equipping machine gun belts.

This analogue has a number of disadvantages, which boil down to large dimensions, many parts, heavy weight and requirements for complex maintenance, which is not always possible in the field. In addition, this device does not allow it to be used suspended.

The purpose of the group of inventions is to expand the arsenal of devices in this field of technology and create a compact, unpretentious device that can be used in the field, including by wounded soldiers.

The technical result of the group of inventions is the creation of a compact device that makes it possible to equip machine gun belts by weight, without the need to secure the device on a hard surface to prepare it for work, while at the same time achieving ease of use and high speed of loading machine gun belts in the field.

The technical result is achieved through a device for loading machine gun belts, which consists of a housing [1] in which guide grooves for the belt are made. A drum [4] is installed inside the housing and is capable of rotating on an axis [9] fixed in the housing; the drum is pressed against a lever [3] by means of a spring [7], which is configured to rotate on an axis [10] fixed in the housing and equipped with springs [6], in the upper part of the body there is a latch [2], which is fixed on the axis [11] and equipped with a spring [8], in the rear part of the body there is a handle [5], the drum and lever are made with teeth that form single-acting ratchet mechanism.

The method of operation of the device for loading machine gun belts is that an empty belt is inserted into the body from the entrance side, the empty link is placed in the center of the body, the latch [2] is released and fixes the empty belt link opposite the lever [3] by spring force [8], then , with the lever [3] fully released, the cartridge is inserted by hand into the link held by the latch, the lever [3] is pressed all the way, simultaneously with the cartridge being sent, the drum moves along the axis [9] in the direction from the lever and at the end of the movement the drum returns to its original position by force springs [7], their teeth engaging with the counter tooth on the lever [3], after the lever [3] is released and the springs [6] return it to its original position, the drum [4] turns and pulls the tape one link into the loaded cartridge , at the end of the movement of the belt, fixes the next link.

The proposed technical solution is illustrated in the drawings, where: FIG. 1 – left view; Fig.2 – right view; fig. 3 – top view; fig. 4 – rear view; fig. 5 – general view of the device; fig. 6 – explosive diagram of the device indicating the details of the device; fig. 7 – section along the normal axis of the drum in the front projection with tape and cartridges, Fig. 8 – top view with tape and cartridges.

The following parts are indicated by positions (Fig. 6):

2 – clamp;

3 – lever;

4 – drum;

5 – handle;

6 – springs (2 pcs);

7 – spring;

The device consists of a housing [1], in which guide grooves for the tape are made, with a drum [4] located inside it, rotating on an axis fixed in the housing [9]. The drum is pressed by means of a spring [7] to a lever [3], which rotates on an axis [10] fixed in the housing and equipped with springs [6]. In the upper part of the housing there is a latch [2], fixed to the axis [11] and equipped with a spring [8]. There is a handle [5] located at the rear of the body.

The axle [10] is mounted in the housing [1] and holds the lever [3], allowing it to rotate. Springs [6] with one end cling to the body [1], with the other end to the lever [3], thus, when you press the lever [3], the springs [6] are stretched, and when you release the lever [3], the springs [6] return it to initial position. The axle [9] is mounted in the housing [1], holding the spring [7] and the drum [4], allowing the drum [4] to rotate and the spring [7] to compress and decompress along the axle [9], returning the drum to its original position at the end lever stroke [3]. The axle [11] is mounted in the housing [1], holding the latch [2] and the spring [8], allowing the latch [2] to rotate, and the spring [8] to return the latch to its original position, thereby creating pressure on the tape. The handle [5] is attached to the body [1], allowing you to hold the device suspended.

The device works as follows.

The device is taken in the hand by the handle [5], the latch [2] is raised by pressing it and turning on the axis [11], the empty tape is inserted into the body from the entrance side, the empty link is placed in the center of the body, the latch [2] is released and locks an empty belt link opposite the lever [3] by the force of the spring [8]. Then, with the lever [3] fully released, without applying force, the cartridge is inserted as deeply as possible into the link held by the latch with the other hand. After which, using the necessary force, the lever [3], rotating on the axis [10], is pressed all the way, thereby the cartridge is sent to the link to the end due to the pressure of the upper part of the lever on the cartridge case welt. Simultaneously with the chambering of the cartridge, the drum [4] moves along the axis [9] in the direction from the lever and at the end of the movement, the drum, due to the spring [7], returns to its original position, engaging its teeth with the counter tooth on the lever [3]. After this, the lever [3] is released and the springs [6] return it to its original position, and due to the engagement in the ratchet mechanism, the drum [4] rotates and pulls the tape onto one link due to the stop in the loaded cartridge, while overcoming the clamping force of the latch [ 2], which at the end of the belt movement fixes the next link.

Thus, during one cycle of operation of the device, one cartridge is loaded into the belt and the belt moves to the position for loading the next cartridge.

If there is no cartridge in the link, the drum [4] will rotate idle, without pulling the tape. If the tape is not fully loaded, the device allows you to remove it by lifting the latch [2] and manually pull the rest of the tape through. When using a partially loaded belt, the device allows, by lifting the latch [2], insert the tape into the body from the exit side of the loaded part and pull it manually until it locks in front of the nearest cartridge loaded into the tape and continue loading the belt.

The device is assembled using simple and well-known methods, since it consists of a body, a lever and a handle, which makes it possible to hold and use the device suspended. The presence of the latch is due to the fact that it ensures positioning and retention of the tape in the housing. The drum in the device body, when turned, draws the tape after loading the next cartridge, and, due to the presence of teeth on the drum and the lever, the latter combine a one-way ratchet mechanism that ensures rotation of the drum in the process of returning the lever to its original position after loading the next cartridge, where the lever is the drive of the mechanism.

The proposed device for loading machine gun belts has passed all the necessary tests under various climatic conditions and has proven itself to be a reliable, durable device that does not require complex and expensive maintenance and is capable of solving assigned tasks in combat conditions, loading machine gun belts as quickly and easily as possible even when hit dirt, water, dust on it, while the loading speed of machine gun belts is very high.

The device was tested with 7.62x54R caliber cartridges, but in some versions the proposed device can be made to load machine gun belts with cartridges of other calibers. During the manufacture and assembly of the device, it allows the use of parts of various sizes, that is, during the development and design of the device, it was planned and provided for the use of the device for various calibers of cartridges, such as: 5.45x39, 5.56x45, 7.62x39, 7.62x51, etc. That is, modifications of the device are possible, including for an export version or, if necessary, for loading foreign cartridges. In addition, this mechanism allows you to load belts with larger caliber cartridges, for example, 12.7x108R.

The method of operation of the device is simple and efficient, does not require any additional equipment or fasteners, and allows even wounded soldiers to charge the machine gun belt, since the device is lightweight and easy to use.
