Abstract

4256. Loudon, G. A. Feb. 19. Mine signalling systems. - In arrangements in which electric signals or telephone messages are transmitted through a wire embedded in the haulage - cable of a minelift &c., the battery and bell or other signalling-apparatus at the winding end of the cable is mounted on the winding-drum itself, so as to dispense with sliding contacts. There may be several wires connected to different bells, and switches for connecting up a telephone in place of a bell.
