Abstract

20,685. Sutton, J., and Sutton, G. J. Sept. 5. Electro-magnetic switches; interlocked switches. - An interlocking device for a number of separate relays for connecting and disconnecting telegraph, telephone, fire-alarm signalling, or other circuits consists of a drum c standing beneath the various relay armatures e and acting to prevent their movement up to contacts k unless holes g register with projections h. By means of a separate unlocking electro-magnet, the drum is set free and begins to revolve under the influence of a clock-work or other motor as soon as a current is sent to anyone of the relay magnets, the armature of which closes up when the hole is in register and temporarily keeps the drum in position to lock all the other armatures. The circuit of the relay magnet may be automatically broken when the signalling or other operation is complete. Calls received while a previous call is being transmitted are held up and subsequently passed through in definite order.
