Telegraph Register

<< >>
Description (Brief)
This “Aero-Morse” telegraph register is built into an enclosed wooden case, possibly for use in early aircraft. Telegraph devices in the early era of aviation were often enclosed in order to prevent sparks from igniting gas vapors.
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.
