Abstract
636,998. Guns. BREVETS AERO-MECANIQUES SOC. ANON. Feb. 12, 1948, No. 4183. Convention date, Feb. 24, 1947. [Class 92 (ii)] [Also in Group XXIV] A sear system for holding a moving gun part (such as the breech-block of a gas-operated automatic gun) against the action of a high return force (such as that of a return spring) is divided into two portions, the masses of which, when the sear is engaged, are set in motion successively against the action of restraining springs. In the form shown, the breech-block 2, Fig. 1, of an automatic gun, which is subject to the action of a strong return spring (not shown), is retained in open position by a pivoted sear 3 released by a rod 3a. The sear has a pin-and-slot connection 8, 7 with a supporting block 6 having springs 9, 10, Fig. 2, compressed by fixed plungers 11, 13 when the sear and block move forwardly due to the impact of the breech-block on the sear. The arrangement is such that the sear 3 first moves against the action of spring 9 alone and then the sear and block move against the action of all three springs. The plungers 13 may bear against a fibre block 14 and, if desired, may be braked by hydraulic dashpot action in the cylinders 6a, 6b.
