Abstract

234,974. Stone & Co., Ltd., J., and Midgley, A. H. May 12, 1924. Holders.-A block f carrying contacts h slides in a tubular casing a against the action of a spring k, projections g on the block engaging with guide slots b in the casing. The body of the block is of spherical form with flattened sides, so that the block can be introduced into the casing a lengthwise and then turned to bring the projections g into the slots b. The leads enter the casing through a curved tube d having a flange e engaging with a screw-cap c on the casing so as to give a swivelling connection between the tube and the casing.
