Abstract
592,004. Electrode holders. GENERAL ELECTRIC CO., Ltd., BAKER, W. F., and PICKERING, I. J. Oct. 23, 1944, No. 20491. [Class 39 (iii)] [Also in Group XXXVII] In a welding electrode holder, depression of a lever 19 or other control member bearing on an insulating thimble 17 sliding on a guide pin 16, closes a double-break electric switch connecting the supply to the electrode gripping means, by depressing a bridge element 14 carrying contacts 15, against a spring 18, so as to bridge further contacts 11, 13. The surfaces of the switch contacts are preferably curved, Fig. 3 (not shown), so as to provide point contact between them. In the example shown in Fig. 1, the switch is mounted in a tubular moulded insulating body 1 carrying a copper head 2 having a stepped axial bore 3 in which slides a spring-pressed copper plunger 7. The plunger has a detachable nose 24 which holds an electrode 6 inserted into the head. The plunger may be retracted against a spring 8 by swinging. the lever 19 outwards, as described in Specification 593,350. In a modification, Fig. 2 (not shown), the electrode is held by means of a moulded insulating ferrule with protective metal tip, screwed on to a copper rod having a hole into which the electrode is inserted. The copper rod is fixedly mounted in a tubular holder and the switching arrangement is similar to that in Fig. 1. In both cases the relative angular disposition of the electrode and control lever may be varied as desired by providing two or more apertures in the head or rod.
