Abstract

355,888. Plug and two-part couplings. TUCKER, J. B., Kings Road, Tyseley, Birmingham. July 5, 1930, No. 20401. [Class 38 (i).] In a combined switch and plug-coupling the socket a has two slots a<1> through which rollers d project to grip the plug frictionally, the rollers being wedged between the inclined faces b2 on the casing b and the plug f by a spring-pressed plate e. The extended pivot pin of the switch-operating handle h<2> has mounted on it a cam h<3> which, when the switch is in the " off " position, presses the plate e down in order to allow the plug to be inserted or removed. Balls or blocks may be used instead of rollers. A modified form for gripping a flat-blade contact has only one inclined face. Specification 319,058, [Class 38 (i), Electric couplings &c.], is referred to.
