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.
