Telegraph Register

<< >>
Description (Brief)
This telegraph register shows refinements made by the late 1800s. A heavy brass casing holds the spring-powered clockwork mechanism while the mass-produced electromagnets are set outside the case at one end. 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.
