Abstract
18,320. Hooker, L. E. Aug. 9. Cupping.-Closed-end tubes used as blasting- caps &c. are made by forcing the end of a thin seamless copper tube into a grooved or fluted plunger 11 which forms the base of a die 10, by means of a shouldered plunger 12. The bottom of the tube is thus fluted as shown in Fig. 3, and is then pressed into a smooth hole 15 in the die, by a smooth-ended plunger 16, where it assumes the shape shown in Fig. 5. The end, although not actually welded, is tightly closed, but readily opens outwardly to internal pressure so as to explode the dynamite in the blasting-cartridge.
