Telegraph Register

Description (Brief)
This telegraph register was made in the shop of Charles Williams, Jr., in Boston. Williams was an important maker of telegraph equipment and also early telephones designed by Alexander Graham Bell. 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.
