Definitions

  • the present invention relates to an automatic fire-arm in which the pressure of the gases which discharge the bullets is employed for producing the displacement of a member 5. taking part in the operation of the fire arm.
  • Th1s member may be the breech block, or a bolt on the latter, or any other member.
  • the invention relates to an arrangement which, in spite of the sudden action of the gases, permits comparativelyv gentle movements the amplitude of which is easily adj ustable tobe communicated to the said member.
  • the invention consists essentially in employing the gases themselves for exerting a braking action on the movement which they roduce, this result being attained in employng the gases themselves for exerting braking action on the movement which they have produced immediately that the member is put into motion.
  • the present invention is based on the obser-' vation of the fact that the nature of the adjustment which can be obtained by the opposing action of the gases themselves even when the passages of the gases are of fairly large section is such that it is in no way indispensable to oppose, in addition to the motive action of the gases, a'spring which acts as a damping and intermediate device. It has previously been known to construct pparatuses .in which the braking gases mpinge upon the face of the braking mechanism in the cylinder containing the motive gases,
  • Thepresent invention provides in particular for the construction of a fire arm in which act the reverse operations being effected by "aperture 2.
  • the cartridge case ejected by means of a mechanism actuated by a piston upon whichthe gases produced by the combustion of the powder are made to the expansion of one or several springs com pressed by the action of the gases.
  • the gas isadinitted through a fairly large orifice permitting the gases to pass, away rapidly during the return stroke of thg piston, the
  • the invention also provides a means for reducing the braking action by forming holes in the cylinder containing ,the piston, these holes being formed onthe side on which the braking action is produced and leading to the atmosphere.
  • a current of gas is employed for exerting a braking action upon a member unlocking the breech block moved by the gases themselves.
  • the invention also provides for .the. possibility of regulating the strength of the braking action by piercing one or more holes to 13 in the cylinder 3, at the side oh which the gases exerting the braking action are admitted.
  • the said member 20 is formed by a bridge plece sliding in a'directionat right angles to the axis of thebarrel 18 and provided with two lugs or projections such as 20' engaging, for
  • the movement of the member, 20 is immediately damped by a'jet of gas driven in the opposite direction through an orifice .19 in a member mounted upon the barrelby means of screws 19 for example. a
  • the gas is led to the orifice 19 through a duct 19. disposed in the'axis of a second hole 18,.--.formed in the barrel 18.
  • the breech block is displaced 5o backwards under the faction if the gas, com- P pressing the recuperating spring 21 disposed in one of the usual ways.
  • An automatic "fire arm comprising a fixed barrel, a cylinder, a plunber inthis cylinder directly. connected to the breech block,
  • An automatic fire arm comprising a fixed barrel, a cylinder, a plunger in this cylinder directl connected to the breech block, a passage 0 fairly large section extending from the barrel to the end of the cylinder op posed to the breech block, asecond passage of fairly large section extending from a point of the barrel at a distance from the breech-a little greater than for the first passage, to the other-end of the cylinder.
  • An automaticfirearm comprising a fixed barrel, a cylindeiga plunger in this cyl-' inder directly connected to the breech block,
