Telegraph Register

<< >>
Description (Brief)
This is a small telegraph register of that shows the harp design made by James Clark of Philadelphia. The electromagnets and embossing lever are included but there is no tape drive 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.
