Telegraph Register

<< >>
Description (Brief)
L. G. Tillotson and Company of New York made this telegraph register later in the 19th Century. It is stamped with serial number 171 and used a spring-wound tape drive. 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.
