Abstract

550,126. Expanding shell &c. cases; mandrels. INTERNATIONAL COMBUSTION, Ltd., and JAMES, E. R. Dec. 10, 1941, No. 15925. [Classes 83 (ii), 83 (iii) and 83 (iv)] In making projectile shells or casings, a shell &c. of smaller diameter than the finished article is first made by pressing, rolling or stamping, is then expanded by heat treatment and finally forced while hot on to a former b to which it is caused to adhere firmly after contraction due to cooling and due to restriction of contraction by the former, the metal of the shell &c. is stretched beyond its elastic limit. The expanded shell a is forced on to the former by a bumper c. The former may act as a support for the shell during subsequent machining &c.
