Abstract

624,286. Automatic firearms. BREVETS AERO-MECANIQUES SOC. ANON. June 26, 1947, No. 16918. Convention date, July 13, 1946. [Class 92 (ii)] Relates to automatic firearms of the kind in which gases from the barrel 10 act upon a driving device 33 which, through a transmission system in the breech casing 11, acts upon reciprocating members 14 whose function is to lock the reciprocating breech block 12 in the closed position. According to the invention the transmission system consists of at least two freely slidable push pieces 41, 42 disposed end to end ; by this means rebounding of the parts is avoided. The gun shown has 'the Hispano action, the members 14 coacting with a pivoted locking piece 13 on the breech block, and the locking piece coacting with a fixed cross-piece 28. The device 33 houses a spring 39 which urges the device to the forward position shown.
