Burroughs Class 3 Adding Machine


This full keyboard printing manually operated machine has a metal frame painted black, with the area under the keyboard green. Each of the nine columns of color-coded plastic keys has nine keys. On the left of the number keys are subtotal and total keys. Above these are non-add, non-print, and repeat keys. A crank for operating the machine is on the right side. The sum appears in a row of nine windows at the front of the machine.

At the back is the visible printing mechanism and a 30.8 cm. carriage (this dimension does not include the carriage handles). The carriage can be shifted, is wide enough for single sheets stationery, and has a counter that rings a bell at zero. A serrated edge tears the paper tape. The paper holder presently has no paper. The ribbon is stored in separate canisters.

The machine is marked behind the keyboard: Burroughs. It is marked at the front: 3-899304. It is marked on the back: Burroughs (/) THIS MACHINE PROTECTED BY U.S. AND FOREIGN PATENTS. The date was given by the lender when the machine came to the Smithsonian Institution in 1924, and agrees with other listings. The object recently was donated to the Institution by Unisys Corporation.
