Burroughs Style No. 1 Adding Machine

This manually operated full keyboard printing adding machine has a metal mechanism. The metal case is painted black and has glass sides. In addition to nine columns of black and white plastic keys, the machine has a repeat key on the right and a total key on the left. Nine numeral wheels are in front. The narrow carriage with paper tape is not visible from the front (e.g. not visible printing). The glass plate is missing from the front of the machine.
The machine is marked at the top: Style No 1. It is marked at the front: BURROUGHS ADDING MACHINE CO. (/) DETROIT, U.S.A. Below this a list of seven patents with dates ranging from August 21, 1888, to December 13, 1898. It is marked on a metal tag attached to the front: No. 798-S. It was model #89 in the collection of the Patent Division of Burroughs Corporation.
The Burroughs Style No. 1 adding machine (later called the Model No. 1) was manufactured with serial numbers less than 2254 from 1895 to 1908. In January 1905, the American Arithmometer Company took the name Burroughs Adding Machine Company. Hence this machine appears to date from about 1905.
