ABSTRACT:
A breech-closing mechanism for an automatic rifle having a breech chamber and a first locking and stop device comprises a longitudinally movable slide formed with a cam slot, a second locking device rigid with a longitudinally slidably bolt mounted in the slide and rotatable relative thereto. A longitudinally movable locking member is non-rotatably mounted in the slide and a radial cam follower pin is rigid with the bolt and extends through an angled slot in the locking member into the cam slot. The locking member is spring-urged forwardly relative to the slide and is carried along by the slide into engagement with the first locking and stop device. The slide moves forwardly relative to the locking member against the spring force when the locking member is in said engagement until the pin is at the forward end of a longitudinal arm of the angled slot. The pin cooperates with the cam slot to transmit a longitudinal movement of the slide to the bolt when the pin extends through the arm and enters a transverse arm at the forward end to cooperate with the cam slot to move the bolt between first and second rotational positions.
