Abstract

783,023. Ammunition cartridge cases. PAULVE, M. L. A. Aug. 19, 1955 [Sept. 4, 1954], No. 23987/55. Class 9(1) A cartridge case moulded from synthetic plastic materials with a tubular wall 2 and integral base 3 having a central boss 4 extending into the case to accommodate the primer elements has a striker 8 embedded in the boss during the moulding process. Alternatively the striker may be fitted or screwed later into a recess formed during moulding. Flash holes 9 in the boss may be covered with a thin film 10 of plastic material formed during the moulding process or the holes may be covered later with a thin sheet of any suitable material. A primer cup 6 is placed in the cavity of the boss and secured by crimping the edges 11 of the cavity. In a modification, a metal sheath covers the case. The case may also be of cardboard with a base of plastic or an inner plastic coating. Specification 711,650 is referred to.
