Telegraph Register

Description (Brief)
This telegraph register is serial number 80 made by Charles T. Chester of New York. Set on a marble base, the unit was driven by a weight suspended by a string that passed through the hole in the base. Like a clock, the key was used to rewind the mechanism. 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.
