Telegraph Register

Description (Brief):

This telegraph register, purportedly from Japan, came to the Smithsonian in 1911 from the U. S. Department of the Interior. While the electromagnets and tape reel appear conventional, there is no obvious tape drive mechanism so perhaps a separate weight or spring-mechanism was used. Telegraph registers are electrically-activated printers that receive Morse code messages. The message travels as a series of electrical pulses through a wire. The pulses energize the register’s electromagnets which move a lever-arm holding a pen or stylus. A clockwork mechanism pulls a strip of paper across the pen or stylus, recording the message. Short pulses draw or emboss a dot, slightly longer pulses a dash. The sequence of dots and dashes represent letters and numbers.
