Abstract

639,774. Percussion firing mechanism. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 29, 1946, No. 25999. Convention date, Aug. 30, 1945. [Class 92 (ii)] [Also in Group XXX VII] An explosive device used to trip and assist in opening a circuit - breaker (see Group XXXVII) comprises a spring- loaded firing pin 54 normally held by pivoted latch 53 and adapted to be released by an electromagnet 55 to fire a cartridge 50 in sliding breech-block 49. The explosion drives down a piston 48 to operate the circuitbreaker mechanism. Specifications 26694/01, [Class 38], 616,218, and U.S.A. Specification 723,183 are referred to.
