For your consideration is this Calculagraph made by the Calculagraph Co. in Harrison, NJ. The Calculagraph was invented by Henry Abbot, a New York watchmaker, in 1897. Abbot invented the Calculagraph to mechanically calculate and print the elapsed time between two events. They had many applications from tracking table usage in pool halls, to clocking the duration of toll telephone calls, as well as employee time clocks use on the railroads. "The unit consists of a clock and a precision gear-based set of three printing wheels, which print on standardized accounting tickets." (Wikipedia) This Calculagraph is electric, but is not working, as there is no cord. This Calculagraph is in excellent aesthetic condition and has a wonderful 'steampunk" look. It measures about 9" across x 9.5" tall. For a complete representation of condition and for additional images please call 800-686-4216.
