Telegraph Register

Description (Brief):

This register, made in Liverpool, England, features a paper tape reel that is hidden in the drawer below the printer. The tape passes from the reel, over two wooden rollers, and then through the slit cut in the base plate before being fed into the printer. Presumably this design was used to save space and prevent the paper tape from being accidentally broken. A window set in the base plate allows the operator to see how much paper remains on the reel.

Description (Brief)

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.
