This patent demonstrated the recording and transmitting of Morse code messages. A cardboard disc was placed on top of a rotating plate with spiral grooves. Indentations were embossed onto the cardboard by a needle powered by an electromagnet. These indents formed a recorded message, which could then be transmitted� without needing an operator� to several stations, saving labor.
