Definitions

  • a recoil booster for fully or semi-automatic and single shot firing weapons in which the barrel of the weapon has a mouthpiece arranged near the frontend of the barrel and a stub barrel is inserted in the weapon barrel With a mouthpiece in the rear end of the stub barrel.
  • the mouthpieces have nozzle-like bores which are coaxial with each other.
  • the invention relates to a recoil booster for fully automatic, semi-automatic and/or single-shot firing weapons.
  • the explosive forces produced in the barrel are not sufficient to open the breechblock fully when firing takes place with plastics ammunition used for training purposes, because the resistance of the breechblock is adjusted to the higher forces occurring in firing with live ammunition.
  • Recoil boosters have already been developed in which the recoil is produced by constriction of the outlet path for gases produced when training ammunition is fired.
  • a proposed recoil booster for a machine pistol, or submachine gun consists of a plain barrel whose bore, which is constant throughout, is smaller in diameter than the bore of a barrel intended for live ammunition.
  • the practice ammunition has the same dimensions as the live ammunition.
  • the projectile remains jammed in the barrel, while in the case of fused shells bursts in the barrel are the inevitable result.
  • the constriction of the cross-section of the barrel fast with the weapon which constriction is utilized for the recoil, consists of at least two coaxially arranged mouthpieces substantially defining the front and rear ends of the barrel and provided with nozzle-like bores, one of which mouthpieces is arranged in the region of the chamber and the other in the barrel part which is disposed in front of the barrel muzzle and which is fast with the cradle of the weapon.
  • the gas formed on firing causes the tips of the projectiles to split and to obstruct the front mouthpiece so that the gas leaks slower through the interior of the barrel into a pressure chamber enclosed by the barrel part fast with the cradle and by the barrel guided slidably therein.
  • the pressure developed in the said pressure chamber is directed against the slidable arrangement fast with the weapon, on the rearward movement of which arrangement the automatic ammunition feed and the actuation of the breechblock are set in operation. The excess pressure obtaining during this process can escape through the rear mouthpiece.
  • the front mouthpiece is arranged immedi' ately adjacent the chamber, which makes it possible tolocate in that part of the mouthpiece which faces the chamber a profiled recess in which the tip of the projectile which tip consists, for example, of a plastics material, is accommodated so that it is fully supported.
  • the tip which is split on firing but does not break up, is applied with a sealing action against the profiled recess and thereby prevents the gases escaping in the direction of the breechblock.
  • the front mouthpiece and its recess are so dimensioned and designed that it is not possible either to accommodate the tip of the projectile of a live round of ammunition in the recess, or to accommodate a complete live round of ammunition in the shortened chamber when the breech is closed. As a result of this precaution, serious accidents occasioned by mistaking live ammunition for practice ammunition are reliably avoided.
  • FIG. 1 shows diagrammatically in longitudinal section a gas-operated gun with rearward movement of the housing and having a recoil-boosting arrangement embodying the invention
  • FIG. 2 shows a portion of FIG. 1 on a larger scale.
  • FIG. 1 shows that there are, slidably mounted in a barrel part 1 of the gun'and fast with a gun cradle, a stub barrel 2 and a barrel 3 inserted in the barrel 1 and fast with the weapon, and also a breechblock 4.
  • Reference number '5 represents the chamber of the gun and the reference number 6 the gas duct required for driving the breechblock.
  • the mouthpiece 7 has a .very narrow bore 8 which is adjoined in the direction of the chamber 5 by a profiled recess 9.
  • the mouthpiece 7 has a collar 10, the bore 11 of which matches that of the barrel 3.
  • the length of the mouthpiece 7 is so chosen that it projects into the chamber 5. In this way, both the insertion of a live round of ammunition in the chamber 5 and the accommodation of a live round of ammunition in the recess 9 are safely prevented.
  • the mouthpiece 7 may also be so designed that it does not merely receive the tip of the projectile of the round, but the entire round, in which case, the mouthpiece extends over the whole of the chamber 5.
  • the long part facing the breechblock is in the form of a cylindrical bore. This is intended to achieve the longest possible sealing oif of the powder gases in closure systems which open early and to prevent gas creeping to the rear.
  • the recoil booster operates in the following manner:
  • the tapping oil and supply of the gases for the purposes of actuating the breechblock 4 is effected by way of the opening or port 13 and the duct 6.
  • the gas can escape in addition through the venting bores 20 after suitable rearward movement of the barrel 3 fast with the weapon.
  • recoil booster just described is not applied to a specific weapon system only. It may be employed both in recoil-operated guns with rearward movement of the barrel, and in gas-operated guns with or without rearward movement.
  • a fully or semi-automatic and single shot firing weapon comprising a weapon barrel, a mouthpiece arranged near the front end of the barrel, a stub barrel inserted in the weapon barrel, a breech block into which the stub barrel projects, a mouthpiece in the rear end of the stub barrel, said mouthpieces having nozzle-like bores which are coaxial with each other, and a further mouthpiece in the front end of the stub barrel which has a nozzle-like bore coaxial with the other bores.
  • Gas pressure intensifier for fully or semi-automatic and single shot firearms comprising a barrel part having a mouthpiece with a nozzle-like bore therein in an end wall of the barrel part, a barrel movably mounted in the barrel part and having a mouthpiece secured in one end thereof with a nozzle-like bore therein, said mouthpieces forming a pressure chamber in the barrel part, and a mouthpiece in the approximate other end of the barrel and having a nozzle-like bore therein, said mouthpieces being in coaxial relationship with each other as to the bores therein.
