TITLE: Calculating Machine
INVENTOR: William Burroughs
YEAR: 1888
PRINT#: B8116

Burroughs invented the first practical adding and listing machine. In 1886 Burroughs and several St. Louis businessmen formed the American Arithmometer Co. to market the machine. The first machine, however, required a special knack in pulling the handle to execute the calculation correctly. More often than not novice users would get wildly differing sums depending on the vigor they employed in using the invention. In 1893 Burroughs received a patent for an improved calculating machine, which incorporated an oil-filled 'dashpot,' a hydraulic governor. This device enabled the machine to operate properly regardless of the manner with which the handle might be pulled.
