Abstract

550,098. Making shell bodies. WITTER, C. A. March 6, 1941, No. 3056. Convention date, July 16, 1940. Addition to 550,043. [Class 83 (ii)] In making shell bodies as in the parent Specification the blank, after skew-rolling, is passed through a die to reduce it slightly and bring it to approximately the required external diameter such as requires only a light finish machining or grinding. The Specification as open to inspection under Sect. 91 comprises passing through three or more annularly arranged rolls instead of a die. This subject-matter does not appear in the Specification as accepted.
