Definitions

  • the present invention relates to the field of automatic firearms and in particular to automatic weapon of machine gun type that works with cartridge belt.
  • the world-known machine guns can work with cartridges of different configuration.
  • One of the known cartridge types is the cartridge with case that ends with rim (rimmed case head), for example 7.62 x 54R or so called “Russian” type cartridges, which lately have lower application, and the other known type is the cartridge with case that have extraction groove (rimless), for example 7.62 x 51 NATO or so called “NATO” type cartridges, which at the present moment are mainly used.
  • Both cartridge types are used with automatic weapons of machine gun type that work on different principles of extraction the cartridge from the cartridge belt and pushing it into the barrel, namely via separate mechanisms or via direct pushing of the cartridge through the link by the bolt of the weapon.
  • the feed tray of this known weapon has mechanism for cartridge pressing, located near the area of cartridge extraction from the belt that limit the movement of the cartridge forward along the weapon axis and prevents the premature exit of the cartridge from the cartridge link.
  • This mechanism do not fix the cartridge in a certain position to the belt feeding mechanism.
  • Machine guns ihat work with rimmed cartridges, for example the wide used all over the world “KALASHNIKOV” machine guns and “ARSENAL” machine guns do not use the bolt for extraction of the cartridge from the belt link, and in these weapons the cartridge belt passes over the bolt carrier.
  • These machine guns include a barrel with chamber, a receiver to which the barrel is attached, a cover for closing the receiver, a feed tray for guiding the movement of the cartridge belt that is located between the receiver and receiver cover as in the rear end of the feed tray there is a socket for the cartridge extracted from the belt and the size of this socket is
  • first mechanism for extraction of the cartridge from the belt link usually mounted on the bolt carrier called cartridge gripper
  • second mechanism for lowering the cartridge usually mounted into the receiver cover The first mechanism extracts the cartridge and pulls it backwards from the belt, and the second mechanism pushes the backward pulled cartridge and lowers it to the shaped socket in the feed tray from where pushing of the cartridge to the chamber by the bolt will start.
  • the object of the present invention is to provide an automatic weapon that can work with cartridges with extraction groove and the feeding of the cartridge into the barrel to be smooth and under small angle.
  • the proposed automatic weapon fed by cartridge belt including a barrel with chamber, a receiver to which the barrel is attached, a cover for closing the receiver, a feed tray for guiding the movement of the cartridge belt that is located between the receiver and receiver cover as there is a socket for the cartridge extracted from the belt on the feed tray and the size of this socket is conformable to the biggest size of the cartridge, a mechanism for fixing the cartridge belt that is located out of the place for cartridge extraction, a belt feeding mechanism for belt movement, a bolt carrier with bolt for pushing the cartridge into the chamber, a first mechanism for cartridge extraction from the belt, as well as a second mechanism for lowering the cartridge.
  • the weapon also includes at least one mechanism for cartridge fixing to the feed tray before the cartridge extraction from the belt, which mechanism is located in the place of cartridge extraction from the belt.
  • the automatic weapon includes two mechanisms for fixing the cartridge, as the second mechanism for cartridge fixing is located in the place of the cartridge neighboring to the cartridge that will be extracted. This provides the uniform positioning of the cartridges and so improves the reliability of the extraction.
  • the mechanism for fixing the cartridge is of springing type. This provides the reliable fixing of cartridges that have wide tolerances for manufacturing.
  • the mechanism for cartridge fixing is mounted to the receiver cover, which provides easy access to the mechanism.
  • Fig. 1 is a sectional drawing of the receiver, the receiver cover and feed tray of the automatic weapon with two mechanisms for fixing of the cartridge.
  • FIG. 1 On the enclosed Fig. 1 , a sectional drawing of one example embodiment of the invention of the automatic weapon is shown.
  • the shown weapon includes receiver 1 in which a barrel 2 and a bolt carrier 3 are mounted.
  • the receiver 1 is closed by a receiver cover 4, and between the receiver 1 and receiver cover 4 is placed a feed tray 5 that serves for guiding the movement of the cartridge belt 6.
  • the weapon has a mechanism for fixing the cartridge belt 6, as in the present case this mechanism is of springing type.
  • This mechanism in the said embodiment, includes a belt retainer 7 and a belt retainer spring 8, which are mounted on the receiver cover 4.
  • On the receiver cover 4, in the present case, two mechanisms for fixing the cartridge are mounted, as each of them contains of interconnected movable support 9 or 9' and spring 10 or 10' and this spring is attached to the receiver cover 4.
  • this mechanism is attached to the receiver cover 4.
  • both movable supports 9 and 9' are interconnected via an axis 11 which also is mounted to the receiver cover 4 (not shown on Fig.1). Around the axis 11 , the movable supports 9 and 9' can rotate by the force of the springs 10 and 10'.
  • a feeding mechanism for movement of the cartridge belt 6 is shown too.
  • This feeding mechanism includes a belt feed lever 12 and a belt feed pawl 13, interconnected by a feeding pawl spring 14.
  • the feeding pawl spring 14 is of torsion type in this case.
  • the weapon has a mechanism for extracting the cartridge from the belt mounted in this case on the bolt carrier, as well as the mechanism for lowering of the extracted cartridge mounted in this case into the receiver cover, which mechanisms are not shown on the drawing, because they are of commonly known type used and mounted on the conventional machine guns of "KALASHNIKOV” and “ARSENAL” type which work with rimmed cartridges.
  • the automatic weapon has the following course of action: Upon the movement of bolt carrier 3 backward, the belt feeding lever 12 rotates and, via the belt feed pawl 13 pushes the cartridge belt 6 together with the cartridges one step forward in the direction of the belt movement - perpendicularly to the weapon axis. Upon this movement, the first cartridge presses and lifts up the belt retainer 7 and passes below the belt retainer. Under the action of belt retainer spring 8, the belt retainer 7 returns to its initial position and thus prevents the movement of the cartridge belt 6 backwards. An the end of the first step movement , the first cartridge stops just below the moving support 9 and the second cartridge stops under the next moving support 9'.
  • moving supports 9 and 9' are interconnected with the receiver cover 4 via the axis 1 and are situated in accommodated for them slots.
  • the belt feed lever 12 rotates.
  • the belt feed pawl 3 goes downwards, passes below the next cartridge and squeezes the feeding pawl spring 14.
  • the feeding pawl spring 14 lifts the belt feed pawl 13 to its initial position, and in this position, the belt feed pawl 13 is ready to push the next cartridge.
  • the first and the second cartridges are pressed by the moving supports 9 and 9' to the feed tray 5, and the belt retainer 7 prevents the backwards movement of the belt with cartridges.
  • This provides the uniform and reliable positioning of the cartridge for catching the cartridge by the mechanism for cartridge extraction from the belt.
  • the mechanism for the extraction of the cartridge from the belt grips the first cartridge.
  • the mechanism for lowering the cartridge presses it to the socket shaped in the feed tray 5, from where, upon the forward movement of the bolt carrier 3, the bolt starts to push this cartridge to the chamber, and thus the weapon fires.
