Definitions

  • My invention relates to machine guns of the kind in which the loading and ring mechanism is actuated by aid of a reciprocating piston, whose backward stroke is caused by the action of the powder gases.
  • the object of my invention is to provide an improved simple and strong breech mechanism for arms of this kind.
  • FIG. 1 is a partly diagrammatic side view of the breech part of a gun in accordance withl my invention, in section through the oreech casing, and with the respective parts in firing position.
  • Fig. 2 is a corresponding side view, showk ing the parts in their eXtreme retracted positions.
  • Fig. 3 is a part sectional view showing the firing mechanism.
  • This piston is in kno-wn manner provided with means for actuating the cartridge feed mechanism.
  • This mechanism may be of any known or suitable arrangement and does not form part of this invention, but by way of illustration, is shown a cartridge feed, actuated by a cam 4 on the piston, said cam engaging a spring controlled wheel or disc 6, fastened to the rear end of a cartridge drum 5, the cam 4 turning the disc 6 and compressing its spring (not shown) during the backward stroke of the piston 3, thereby enabling said spring to turn at the right moment the cartridge drum 5 in position toY allow a fresh cartridge to be driven into the chamber ofthe gun barrel.
  • the rearend oftheY said recoil pistonr has turnably ⁇ attached to it a connecting rod 7, whose other end is turnably connected toI a discshaped eccentric or crank 8,' turning about pivots 9 journalled in the side walls ofthe casing 1.
  • this eccentric 8 is turnably connected to the rear ⁇ end off'al rod 10, carrying the tiring mechanism, and the front end of which is turnably connected at 11 to the breech block 20.
  • the firing mechanism as shown in Fig. 3, comprises, a plunger 22, actuated by a compression spring 23, and terminating in a hook 24 for catching on an angle 25 of rod 10, from which angle it is released, at the proper time, by pin 16.
  • the mechanism operates in the following manner:
  • the trigger arm 15 On pressing the trigger 14 the trigger arm 15 will depress the spring actuated pin 16 against thel action of its spring, thereby actuating the tiring mechanism enclosed in the rod 10 and causing the firing pin of the breech block to be released, whereby the shot is fired.
  • the recoil piston 3 On the firing of the shot the recoil piston 3 is thrown backwards by the action of the powder gases, thereby moving the connecting rod 7 and the eccentric 8 to the positions illustrated in Fig. 2, and simultaneously cocking the firing spring and extracting the empty shell by the ejector tooth 18 in the breech block, and simultaneously arming the firing mechanism enclosed in the rod 10A by aid of a tooth 17 on the rear end of the iston 3 striking against a nose 21 of the firing mechanism.
  • the backward throw of the eccentric disc 8 is limited by an abutment 19, arranged at the rear end of the casing 1.
  • This abutment may suitably be arranged resilient.
  • the mechanism is by the action of the recoil sprin thrown forwards to the position shown in Fig. 1, the
  • breech 'block 20 hereby driving a fresh cartridge from the drum 5 into the chamber of the barrel, the drum 5 having meantime been rotated one step by the disc 6.
