Abstract

346,534. Plug couplings. MARR, G., 18, Euston Buildings, George Street, Euston Square, London. March 1, 1930, No. 6827. [Class 38 (i).] A combined switch and plug coupling of the type in which a plate actuated by the switch dolly and locked by a spring-controlled plug 1 operated by one of the plug pins prevents the switch being moved to the "on" position until the plug has been inserted and prevents the plug being removed until the switch is in the "off" position has the locking plunger mounted on a pivoted lever the free end of which projects through a slot in the socket. A sliding plate A, Fig. 3, connected to the switch dolly B, is provided with a hole I, Fig. 4, that is engaged by a plunger P mounted on the pivoted lever N and a keyhole slot F. The socket Q has a slot T through which the end of the lever N passes and has two slots S through which the restricted parts of the keyhole slot project to engage the earth pin of the plug. When the plug is inserted the lever N is pressed down and the plunger is removed from engagement with the sliding plate. This allows the switch to be moved to the "on" position and the plate is moved to a position in which the restricted part of the keyhole slot engages the restriction of the plug pin and prevents the plug being removed.
