Atkinson Counting Register, U.S. Patent Office Model

Atkinson, Alexander P. · 1874

This roughly built wooden and metal device is the U.S. patent model for a counter patented by Alexander P. Atkinson of Vermont, Ill., on November 7, 1871. It has an open wooden frame, with a window at the front for viewing the registering wheels. The three wheels are mounted on a crosswise shaft, along with a fourth wheel, which drives the others. Lowering a crank on the right side of the frame moves the driving wheel and the rightmost registering wheel one unit back. Returning the crank upright moves the driving but not the registering wheel.
