Abstract
243,254. Glover, P. S. June 2, 1925. Two-part couplings combined with electric switches.-A plug 4 of lignum vitµ &c., carrying contacts 9, 10 connected to extension leads 13, 14 cannot be inserted in or withdrawn from a casing a, when a tumbler or other switch k contained therein is " on." The knob k<1> of the switch is operated by a forked lever t secured to a shaft o which passes through the lid of thecasing and is turned by a handle exterior to the casing. When the shaft o is turned counterclockwise from the position shown, the switch is opened and a cam r on the shaft then engages contact members g, g<1> pivoted at h, h' to a fixed insulating block f, and moves them against the action of springs i, j<1>, so that their ends i, i<1> are withdrawn from recesses 7, 8 in the plug 4. The plug can thereupon be withdrawn and the opening in the casing closed by a cover 18. When the plug is in position, the circuit is completed through the ends i, i' of the members g, g' contacting with the contacts 9, 10. A pin 17 in the casing co-operates with a slot 16 in the back of the plug to ensure correct positioning of the plug. Fuses may also be enclosed in the casing.
