Abstract

2315. Hammond, G. Jan. 28. Breech actions, sliding breech-block. - Consists in special means for operating the rotary breech-bolt of an automatic gun, and in a safety device to prevent firing of the gun unless the bolt is completely locked. The rotary locking movement is effected by a torsion spring mounted within the bolt and having one end abutting against a shoulder on a non-rotary sleeve on the firing-pin and the other against a shoulder on a bush 30 keyed to the bolt. A spring latch 48, Fig. 5, locks the sleeve to the bolt when the bolt is removed from the gun. The bolt is unlocked during the forward movement and retracted during the backward movement of a reciprocating slide 26 moved forwards by the powder gases acting on a sleeve 18 at the muzzle, and backwards by a spring 24. During the forward movement, a lug 56 on the slide engages a cam-groove 57, Fig. 13, in the bolt and rotates it; when the slide reaches its forward position, the lug 56 slips over a spring catch 61, Fig. 10, on the bolt, which is hence retracted to open the breech during the return movement of the slide. The catch is released when the slide regains its rearward position. During the forward movement of the bolt, the lug 56 slides idly in a straight groove 58, Fig. 13, in the bolt. The bolt return spring 74, Fig. 1, is arranged at the back of the grip and acts on the bolt through a bell-crank lever, The safety device comprises a fin 63 on the firing-pin adapted to register with a recess in the bolt only when the bolt is in its locked position.
