Abstract
390,445. Two-part couplings. PRITCHARD, S. C., Bishopswood, The Bishops Avenue, East Finchley, London. Oct. 20, 1932, No. 29357. [Class 38 (i).] An earthing contact for a bayonet-type fitting comprises a resilient member moving in a groove or recess in the side of the fitting and adapted to make contact with the inner metallic wall of the socket. In one construction, Fig. 1, a leaf spring 9 projects from a groove 8 and is secured at one end to an extra terminal 11. The three terminals are separated by a threewalled insulating member 13 which may be detachably mounted by means of projections engaging slots or holes in the inner face 5 of the fitting. The cap 7 may have an adapting bush 14 for cables of different sizes. In another construction, Fig. 4, the earthing contact comprises a spring-controlled ball or plunger 15 with chamfered or spherical end mounted in a metal tube 16 held in position by a screwed extension 17 on the terminal 11.
