Telau′tograph, an ingenious instrument invented by Elisha Gray, for reproducing autograph-writing, messages, drawings and sketches in facsimile and transmitting such to places distant many miles apart by means of an electric motor driven by a local battery. The message, at the receiving point, is written on the sketch drawn by pencil on a roll of paper drawn over drums, and so arranged that they can be shipped forward by the operator at intervals, as each line of writing or drawing is finished. The receiving-pen, which is a small glass-tube furnished with writing-fluid by capillary attraction, being controlled by the current-impulses from the transmitting pencil, it follows and reproduces all its movements, which are then electrically transmitted.
