Telautograph
an instrument which will at any distance transmit accurately and to the smallest detail in exact facsimile anything that may be written or drawn on the transmitting device. Two instruments are used, one to transmit and one to record. Both are nearly identical in form, size, and general arrangement, and each carries a wide strip of paper controlled by a synchronizing device which causes the one to follow the movements of the other. On the transmitter anything can be written or drawn and the recording stylus of the receiving instrument follows the movements of the transmitting stylus or pencil and thus produces an exact facsimile of the writing or drawing. The The Telechirograph invented by Gruhn is a modification of the Telautograph.
