Device used to punch holes in paper tape as part of an electric telegraph system. Characters typed on the keyboard were converted according to a defined code into a pattern of perforations in the paper tape. The punched tape was fed through a transmitter which converted the pattern of holes into pulses of electrical current for transmission over the telegraph line to the receiving station.
