Telegraph Register

Description (Brief)
This register, made in Paris, France, bears the stamping “Btes S.G.D.G.”, or Breuvete Sans garantie du gouvernement (patent without State guarantee). 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.
