Abstract
250,001. Cotterell, G. March 19, 1925. Clockwork actuation.-A time switch particularly applicable for controlllng wireless telephone receiving sets, but also of use for switching on and off shop window lamps &c., comprises a clock b, Fig. 1, located in a panel a, and provided with a laminated brush e which revolves with the hour hand and passes over contact studs f, the brush being in contact with one stud before leaving the preceding one. Each stud is connected to a corresponding socket g adapted to receive a wander plug n. When the brush is on any contact, the corresponding socket of which is plugged, a circuit is completed from a terminal j through the clock, brush, contact, socket and plug to another terminal k. An additional plug can be used in circuit with a bell r. In a modified construction shown in Fig. 4, the contacts f are extended radially and are surrounded by a circular bus-bar m, to which they can be connected by inserting plugs in the gaps r.
