Summary
Description Telautograph Receiver and Transmitter.png |
English:
A perspective view of the first commercial model of Elisha Gray's Telautograph transmitter and receiver, identical in appearance to those exhibited at the Chicago Worlds Fair in 1893. The left-hand transmitter unit would encode the position of a writing pencil as a series of pulsed currents of different levels and polarities, to be transmitted to and reproduced by the receiver on the left, where a capillary tube ink pen is moved across the paper by electromagnetic clutches and escapements.
