Abstract

288,621. Schneider et Cie. April 14, 1927, [Convention date]. Ordnance, muzzle-loading; design; chambers; breech mechanism.-The base of a projectile and the breech-block or obturator of a muzzle-loading or other gun are made with interengaging male and female parts forming a chamber for the propellent cartridge. In the form shown in Fig. 1, the cartridge G is in a socket F in the base of the projectile C, which socket fits over a projection D on the breech base B of the gun A. The cartridge is fired by a primer H struck by a fixed or movable firing pin E. The gases are confined within the socket F until this leaves the projection D; the gases then expand into the barrel A and partly escape through a hole I. In modifications, a socket containing the cartridge at the base of the projectile fits into a recess in the breech base of the gun, or into a recess in an obturator carried by a. breech-block, or over a projection on the obturator. In another modification, Fig. 7, the cartridge G is in a recess in a projection D on an obturator K, which projection fits into a socket F at the base of the projectile. Specifications 128,279, 201,527, and 237,880 are referred to.
