Object Details
- J. H. Bunnell & Co.
- Description (Brief)
- This later-model Bunnell telegraph register came in a portable carrying case and included capacitors that allowed researchers at the Bureau of Standards to conduct experiments.
- 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.
