About This Company

In 1885, Dorr Eugene Felt (1862-1930), of Chicago, used a wooden macaroni box, staples, rubber bands, wire, string, and meat skewers to make a prototype of what became the first practical multiple order calculator to use a keyboard, the Comptometer. The "Macaroni Box" prototype is now on display at the Smithsonian Institution in Washington.

The design was based on a fast carry mechanism that acted while the keys returned to their original state after being depressed. A detent toothed lever controlled the wheel momentum by bringing the wheel to a full stop.

By 1886 Felt had completed his first metal prototype. In March 1887 he applied for a patent which was granted in October 11, 1887 (US Patent 371,496). Then he started the Felt & Tarrant Mfg. Co. in partnership with Robert Tarrant.

In 1889, Dorr E. Felt obtained a patent for his Comptograph which was basically a Comptometer with a printing device. This machine is now in the Smithsonian Museum. In 1890 Felt also produced a model with wide carriage able to print several columns of numbers.

In 1957 the Felt & Tarrant Mfg. Co. became the Comptometer Corporation and had manufacturing operations in the United States and England.  The English operation along with the rights to use the name Comptometer were sold in 1960 to Control Systems Limited, owner of the Bell Punch Company Ltd. and its distributor Sumlock Ltd. which became Sumlock Comptometer Ltd.  The US manufacturing operations were stopped and Comptometers were manufactured in England by using a plastic-metal mechanism of inferior quality [14].   In 1961, the Comptometer Corporation merged with Victor Adding Machine Co. to form the Victor Comptometer Corporation [8].  The new models introduced by Victor used the internal Bell-Punch mechanism.
