Abstract

469,146. Controlling electric forging operations by radiant heat. AUSTIN MOTOR CO., Ltd., WALKER, H. W., and BLUNDELL, P. J. March 30, 1936, No. 9331. [Class 40 (iii)] [Also in Group XXII] In electric forging-machines a temperature sensitive cell sets in operation interruptions in the heating current through the work. As shown an hydraulic cylinder C operates a ram C pressing the work A against an anvil D. A relay switch g operated by an electric cell G operates a trip to close contact at 38, 39 and energize a motor H to drive through gearing a cam J intermittently opening and closing a contact 40 to produce intermittent current in the work. As the upsetting continues a cam K on the ram operates a switch to break contact and cut out a solenoid and motor and the current becomes continuous.
