Definitions

  • My invention relates to guns, more articularly to semi-automatic rifles adapte to be fired from the shoulder, and aims to provide a simplified, compact, rugged but lightwei ht, and otherwise improved mechanism of t e class described. While certain features of the invention relate especially to semi-automatic guns, that is, self-loading single-fire devices, other features are equally useful in connection either with handoperated or with full automatic weapons, including machine guns.

  • the barrel is preferably rovided with one or more upwardly directed ports 22, herein in the plane of said collar portion 21, the latter being ported in radial line with the barrel ports, whereby a portion of the gas is released upwardly, counteracting any tendenc of the muzz e to climb.
  • the barrel terminates in a muzzle nut 23 having a series of radially disposed vents 24, whereby additional gas is released to atmosphere prior to the exit of the bullet from the barrel. l find in actual practice that such provision materially lessens the recoil.

  • the sliding spring tube 27 is guided in a bearing 34, Fig. 20, depending from a collar .35 inned on the barrel.
  • l have shown a relatively small and short barrelport in combination with a ported piston having a relatively large gas-storage and expansion chamber, the piston port 25a being located intermediate the ends of the cham-
  • high-pressure live gas enters lthe piston 25 through this port, the port in the gas tube 14, and the then registering port 25a in the piston.
  • the gas in the piston reaches a pressure sufficient to overcome the resistance of the action-spring 30 and the reciprocating parts, the piston moves rearwardly, closing the barrel-port.
  • llhe gas is thus trapped in the piston and the gas tube, where it expands, actively, causing a continued smooth rearward movement of the piston.
  • the described gas-mechanism affords a safe and positive means for operating the breech-closure, particularly one of the extreme lightness as herein disclosed.
  • the gas is utilized ex ansively rather than by way of a violent initlal impulse or hammer-like blow characteristic of known gas systems employing a free or continuously open port 25a.
  • the parts are .caused to move back under control rather than to be blown back by the initial gas impulse.
  • l trap in the piston or expansion chamber a quantity of live, expanding gas sufcient, at its initial pressure, to over-balance the variable resistance to the breech openingeiort, and at its nal pressure adequate to have completed'the rearward stroke of the piston and other reciprocating parts.
  • the described piston in functionin to drive the breech mechanism, controls t e inflow and outflow of as, on the rearward stroke, and acts as a ucing valve to check the piston speed as it ap roaches the limit of its rearward travel.
  • the return or forward stroke it traps and compresses air, checking the forward speed and aording adequate time for cartridge feed, reducing the likelihood of jamming and of abrasions on the shoulder of' the cartridge case.
  • the compressed air charge being released only throu h the barl port, serves to scavenge an cool the re.
  • the compensating action of the described as mechanism provides for proper, uniform reech action despite variations not only in the resistance to breech-opening eil'ort but also in explosion-'chamber pressures. If eater opening eort is needed, more gas l 1s automatically taken. If abnormally high low the barrel, adordin gas pressures are developed, the inflow of gas is automatically more quickly cut of and less gas is taken. Full functioning of the mechanism may be obtained with chamber pressures varying as widely as between 20,000 pounds below and 20,000 pounds above that of standard army ammunition.
