Abstract
1,265,112. Wads. BASCHIERI & PELLAGRIS S.p.A. 19 May, 1970 [23 May, 1969; 21 Feb., 1970], No. 24226/70. Heading F3A. A cartridge wad comprises a shot container 2, Fig. 1, having a shank part 10, and a gas sealing ring 11 which is adjustable relative to the container to allow for varying charging conditions of shot and explosive in the cartridge prior to firing. The sealing ring is attached to the shank by a frangible connection 12 which is broken to adjust the position of the ring. Upon firing the cartridge, the ring is driven along the shank against the increased frictional resistance of the shank caused by expansion of the shank under the pressure of the propellant gases. In another embodiment. Fig. 4, a frangible connection 16 connects the shank to the container 2. In another embodiment, Fig. 8, a frangible connection between the sealing ring and shank must first be broken so that the ring can be moved along the shank with a projection of the sealing ring engaging the shank between adjacent annular ribs 20. The shank collapses upon firing the cartridge. In another embodiment, Fig. 10, the shank is integral with the sealing ring and is frangibly connected to the container 2. Lugs 22 prevent the entry of explosive material into the hollow shank.
