Abstract

130,061. Smith, S. Jan. 10, 1918. Ordnance breech mechanism. - Relates to breech-screws of the kind having external interrupted threads engaging the gun, and internal interrupted threads engaging the carrier, and consists in constructing the body of the block of cheap material, e.g. a malleable-iron casting and attaching thereto the external and internal threads, a handle for rotating the block, and a pawl for locking the block in the closed position, which separate parts are made of more expensive material, such as phosphor bronze. Fig. 2 shows the external threads 4 formed on separate pieces 3 secured in recesses in the body 1. The internal carrier-engaging threads 5 are formed on a sleeve 6 having a projection 7 to prevent rotation. The handle 8 is attached by screws to the front face of the block, and the locking-pawl 9 is attached bv screws to the handle. The internal and external threads may be carried by upper and lower U-section members 19 as shown in Fig. 15. The thread sections may be dovetailed into the body of the block.
