Elisha Gray's Telautograph Receiver and Transmitter circa 1893
Summary[edit]
| Description |
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. Shared by the American National History Museum and retrieved from the Smithsonian Image Delivery Service in 2023 under CC0 license. Pub date actually unknown. |
