Abstract
487,225. Two-part couplings combined with switches. PARSONS, Ltd., C. H., and HANDLEY, G. B. Nov. 23, 1936, No. 31958. [Class 38 (i)] Closure of the switch of a switch-socket is prevented when the plug-member is withdrawn by a bolt m pivoted to a slide o pressed by a spring p towards the switch but drawn back when the earthing-plug s is inserted by a lever q moved laterally by the plug s and acting on the slide o. The bolt m slides in a guide on a carriage h that is slid upwardly, Fig. 2, when the switch a is closed as shown. When the switch is open and the plug s withdrawn the bolt m is moved by the spring p so that its end engages stop n and prevents movement of the carriage h. When the switch is closed the plug may be locked in the socket by a knife-edge on a lever x pressed into operative position by a spring v, but moved in the opposite direction by a lever w when the switch is opened, as described in Specification 487,224.
