Edison patent

In 1888, Thomas A. Edision, with co-inventor Ezra T. Gilliland were granted a patent for "Railway Signaling" (U.S. No. 384,830). The invention related to signalling systems for communicating between stations and moving trains by induction from the telegraph wires to the roofs of the cars. In such a system, transmitters were vibrators operated by keys to send signals upon the line, and receivers were telephone receivers connected to the ground. The patent was for an innovation to increase the quickness, rapidity and clearness of the vibrations. By making the transmitted vibrations as short and distinct as possible, they may be more clearly reproduced at the receiver.
