Telegraph Register

Description (Brief):

L. G. Tillotson and Company of New York made this telegraph register but the incomplete tape reel holder may have been added by the users in the University of Virginia's Physics Department. 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.
