Abstract

666,478. Making electric contacts. IGRANIC ELECTRIC CO., Ltd. Oct. 16, 1947 [Oct. 18, 1946], No. 27745/47. Classes 83 (ii) and 83 (iv). [Also in Group II] A contact tip is moulded or coined from a single shot which is then welded to a metal support. It may be of silver and be electrically welded to its support by fusion. Forging. - dies.- A shot of the desired size is forged by dies 38, 39, 40, Fig. 6, and welded between the die 38 and an electrode 45, Fig. 8, to a support 44. The die 38 may be of casehardened tool steel or of electrode metal. A machine for forming shot is also described.
