Definitions

  • My invention relates to automatic firearms which have a breech block actuated ,and controlled by a breechblock carrier.
  • -It is an object of this invention to provide for such a Weapon of simple construction vwhich is Aespecially suitable for automatic rifles.
  • a recuperator ⁇ spring is so arranged in connection with the of the firearm as to actuate the movements of the striking member of the firing pin and also to actuate, during the forward movement, the Abreechbiock carrier until the locking position of the breech block is reached.
  • the striker is mounted on the breech block carrier and so arranged as to transmit, during the forward movement, the force of the recuperator spring to the breech block carrier, and to be actuated by the same spring for its striking movement at the end of the forward movement of the breech block.
  • the action cf the striker depends directly on the position of the breech block carrier, so that a or a belated firing with prematurely breech is prevented.
  • the striker may have the form of a lever which is hinged by one end to the breech block carrier, while its other end cooperates, before the end of the forward stroke, with a stop about which the striking lever tilts so as to recede relative to the breech block, while during this relative receding movement the breech block carrier finishes its forward stroke and simultaneously locks the breech block.
  • this stop forms part of the sear, which is actuated by the trigger with the aid of a connecting rod.
  • Fig. 1 is a longitudinal section of 'the rifle with the parts in firing position.
  • Fig. 2 shows,.on an enlarged scale, the cocked striker mechanism before firing.
  • I is the breech case, 2 the barrel, 3y the triggercase and 4 the butt.
  • the cases I and 3 are connected by means of bolts 5 and 6, V
  • the breech mechanism is arranged for freesliding movement. It consists of the breech block carrier 1, the tilting breech block 8 and the hammerlike striking member 9 to which latter is attached, by means of stud I0, the recuperator rod I I, the rear end of which rests on an abutment member I2 acted upon by the recuperator spring I3, Vwhich is arranged in the tube 2'! held in the case 3 by the butt 4;
  • the striker 9 is a leverhinged to the breech block carrier 1 by meansof the pin 24 and formed with a head 23 acting on the ring pin SI accommodated; in the, breech block. 32 is the extractorfor thefempty cartridge cases.
  • the breech block. carrier which is formed with a tooth 29, ⁇ cooperating ⁇ with the tongue 39 of the breech block 8, is connected with the piston rod of thegasfpressure loading-device (not shown).
  • the breech block 8 In thelocking position the breech block 8 abuts against a cross piece 34 below which is removably ⁇ during the movement of the breech block 8, passes through a, longitudinal groove 36 in the bottom face of this block.
  • the ejector is held in the active position by the spring 31 of the lever 38 locking the magazine I9, which is a three-armed lever, the arm 38 being applied against the magazine I9, while arm 33" serves for operation, and arm 38" is the supporting arm.
  • 4I is the ejector opening, through which the magazine I9 may also be lled with cartridges from belts.
  • the trigger mechanism comprises the forked trigger I 6 pivoted to pin I1. Both arms of the fork -carry at their ends locking teeth I8, which serve for locking the manually cocked breech block carrier 1, during the filling of the cartridge magazine I9 from belts or during an exchange of such belts.
  • the trigger I-6 is connected by means of a connecting rod 20, arranged between the arms of the fork, with the sear 2
  • the entire trigger mechanism is acted upon by spring 25 which surrounds a guiding bolt arranged,fthe,eject0r 35, which,
  • the vthe striker hammers is locking position wherein' 26 extending through an aperture in a short arm of the connecting rod 20.
