Definitions

  • a further aim of the present invention is to provide a device in inertia-locked automatic firearms, by means of which it is made possible to prevent a belated ignition of the cartridge in the event of the rupture of the lever controlling the movement of the striker pin.
  • the present invention provides an additional cam or projection carrying back the lever, and consequently the striker pin, as soon as the breech block runs beyond the normal front reversal position.
  • Fig ⁇ 1 is a diagrammatic representation of an
  • Fig.2 is a section through the firearmshowing the disposition of the striker pin and of the members controlling it in the positions they occupy during the forward travel .of the breech block;
  • Fig. 3 is'a section through the firearm showing the dispositon of the striker pin and of. the members controlling it in the firing position;
  • Fig. 4 is a section through the firearm showing the disposition of the striker pin and of the members controlling it in the positions they occupy in the normal front reversal position;
  • Fig. 5 is a section through the firearm showing the disposition of the striker pin and of the members controlling it where there is no cartridge in the chamber;
  • Fig. 6 is a section through the firearm showing the disposition of the striker pin and of the members controlling it in the positions they occupy after the rupture of the said lever controlling the striker pin.
  • the barrel I is inserted in the usual manner into the breech casing 2 in which the breech block 3 reciprocates.
  • the breech block is connected by means of a cross-key t through the breech bar 5, with the tube 6 guiding the recuperator spring 1 which is fitted round the tube.
  • the striker pin 9 is fitted in the breech block 3 in a central bore 8 and its striker point is guided in a member it fitted in the breech block 3.
  • the striker pin comprises two shoulders H and I2 arranged on opposite sides of a lever it pivotally arranged on a pin I l.
  • the lever I3 is provided with two spaced finger-shaped projections l5 and it.
  • a plate ll provided with two cam-like projections 88 and l 9.
  • the cartridge is designated by the reference numeral 20.
  • the breech block 3 pushes a cartridge 20 into the cartridge chamber.
  • the projection it on the lever 53 contacts the cam 18 provided in the path of the breech block.
  • the lever 13 is thus forced to pivot round the pin M and thus causes the striker pin I 7 3 9 to strike the cartridge 20 and to fire it (Fig. 3).
  • Fig. a shows the front reversal or the breech block when the cartridge 20 is; fired.
  • the pro-f jection [5 does not reach as far as the cam l9. If new the breech block again travels rearwards the projection 15 is forced upwards by the cam I8, thus causing the lever I3 again to pivot around the pin l4 and carry back the striker pin 9- (Fig. 2).
