notes: label: Description
content: This lever set non-printing adding machine has an plain steel case painted black. Seven steel levers painted red move in circular arcs between slots in the case. The case is painted along the edges of the slots with the digits from 0 to 9 (large and in black and white) and 9 to 0 (small and in red). The large digits are used in addition, the small ones in subtraction. There is a corrugation or depression in the cover for each digit. Digits are set by placing the index finger in the corresponding depression and raising the lever by the thumb until it is stopped by the finger. They are entered by moving down a metal handle with a wooden knob on the top right. The result appears in nine windows above the levers. If no number is set, moving down the handle zeros the machine. Another handle on the right side zeros digits set incorrectly. A silver-colored repeat lever on the left front is used in multiplication. Moving it down increases the number shown on a number wheel at the front of the machine by one digit each time the entering lever is depressed. The machine has four rubber feet as well as a paper tag.
