Abstract

324,727. Taylor, S. Nov. 6, 1928, Track apparatus actuating signals other than on trains. -An audible signal P on the track is sounded so long as the track relay H is de-energized and the signal V is in a position other than " all clear." Switch S is operated by the signal V and is in series with the contact L of the relay H, which is energized from cells E<1> over resistances E.
