Abstract

488,312. Two-part couplings combined with switches. GENERAL ELECTRIC CO., Ltd., and LANHAM, J. March 18, 1937, No. 798C. [Class 38 (i)] A socket supply fitting 3 having a shutter 9 covering sockets 3 and operated to uncover the sockets by a pin entering the socket 4, is provided with an auxiliary shutter 15 biassed to cover the socket 4 by a spring associated with its pivot 17, but held open against the spring action by a member 19 coupled to a switch lever 7 when the switch is open. If however the switch is closed when the plug is not in the socket, the shutter 15 is released and covers the socket 4 so that the plug cannot be inserted. The shutter 9 may be actuated through a lever pivoted at 11 and a linkage as described in Specification 480,466. Means for preventing removal of the plug when the switch is closed may be provided, but if not, removal of the plug allows the shutter 15 to close preventing re-insertion.
