Abstract

516,920. Forging and squirting cases for shells. STEWART & CO.-, Ltd., D., CROSBIE, J. B. TALBOT-, and MACQUISTEN, A. P. S. July 4, 1938. No. 19697. [Classes 83 (ii) and 83 (iv)] In the production of hollow ammunition shells from a steel billet by a forging and extrusion process, such for example as that described in Specification 469,550, the formation of a fin between the plunger and the wall of the billet receiving chamber is avoided by cooling the billet over an outer annular area on the face of the billet which is subjected to the action of the moving tools. The. billet 6 may be cooled locally immediately prior to the forging and extrusion operation by immersion in a water vessel 1 having an inlet 2, outlet 3, guide plate 5 and an iron pad 4 on which the billet is rested..
