Wheatstone Telegraph

an electromechanical telegraph that records the text of a telegram on a punched tape in Morse code. Invented by C. Wheatstone in 1858, the telegraph consists of the following: a perforator, which punches the tape holes that are grouped in coded combinations; a transmitter, which converts the coded combinations into electrical signals and transmits them to a communications line; and a receiver, such as an undulator, which receives the signals and records them on paper. The Wheatstone telegraph was used during the early development stages of telegraphy.
