Abstract
119,017. Stokes, H. June 1, 1918. Plug couplings combined with electric switches. A tumbler switch in which the ordinary actuating knob is replaced by a lever is secured within a casing 1 and is actuated by a turn member 7 on the casing, the turn members actuating, at the same time, a locking pin 12 which, in the closed position of the switch, is projected into the path of movement of the plug, thereby preventing its insertion or removal. The spindle 8, Fig. 3, of the turn member carries a double-armed crankmember 10, 11 between which the actuating lever of the switch is located. The arm 11 carries a pin 14 moving in a slot in an extension 13 of the locking-pin. The movement of the turn member is limited by the engagement of the extension piece 13 with the inside of the casing or with the spindle 8. The plug is held in place by a screwed collar 16 beyond which the locking-pin extends in the closed position of the switch, which cannot be closed until the collar has been fully screwed down.
