Abstract

678,425. Automatic firearms. BREVETS AERO-MECANIQUES SOC. ANON. Feb. 1, 1951. [Feb. 18, 1950] No. 2559/51. Class 92 (ii). Relates to automatic firearms of the kind in which the breech block is temporarily locked by a sliding system which itself carries at least one relatively sliding mass adapted to prevent rebound of the system, and is characterized in that the sliding mass is so arranged that it undergoes most of the friction exerted between the breech casing and the system during at least the end.of the frontward movement of the system. In the construction shown, the side bars 6 of a gun having a Hispano action, each receive a spring-controlled sliding mass 1 which is guided on its bar by a mortise and tenon arrangement as seen in Fig. 2. Both the side and the upper faces of each mass frictionally engage at 11a, 11b, with the inner wall of the breech casing 2. Such frictional contact may take place only during that part of the stroke when the bars and masses are moving forwards together, the frictional breaking action on the masses ceasing when they move forwards alone. A dovetail joint 13 keeps the mass 11 applied against the bar 6 when the bar is removed from the firearm. In modifications, elastic plates are used to bear against the breech casing or against the mass 6, or the mass 6 may be made, over a portion of its length, in two parts which are urged apart by springs so that one part is made to bear on the breech casing. Specification 598,227 is referred to.
