Adding machine for the Australian pound c.1910, note the complement numbering, and the columns set up for shillings and pence. An adding machine is a class of mechanical calculator, usually specialized for bookkeeping calculations. In the United States, the earliest adding machines were usually built to read in dollars and cents.
In 1909, Burroughs acquired the Pike Adding Machine Co. and in the same year began to sell Burroughs Pike visible adding machines. During the first decade of the 20th century, Burroughs faced competition from both key-driven calculators and a number of rival adding-listing machines, including Dalton, Pike, Standard, Universal, and Wales.
Only the machine built in 1694 is known to exist; it was rediscovered at the end of the 19th century, having spent 250 years forgotten in an attic at the University of Göttingen. [42] The German calculating-machine inventor Arthur Burkhardt was asked to attempt to put Leibniz' machine in operating condition.
The machine could add and subtract six-digit numbers, and indicated an overflow of this capacity by ringing a bell. The adding machine in the base was primarily provided to assist in the difficult task of adding or multiplying two multi-digit numbers. To this end an ingenious arrangement of rotatable Napier's bones were mounted on it.
The Arithmometer, invented in 1820 as a four-operation mechanical calculator, was released to production in 1851 as an adding machine and became the first commercially successful unit; forty years later, by 1890, about 2,500 arithmometers had been sold [16] plus a few hundreds more from two arithmometer clone makers (Burkhardt, Germany, 1878 ...

The adding machine range began with the basic, hand-cranked Class 1 which was only capable of adding. [citation needed] [2] The design included some revolutionary features, foremost of which was the dashpot which governed the speed at which the operating lever could be pulled so allowing the mechanism to operate consistently correctly.

Standard Adding Machine Company was founded in the early 1890s (first records are from 1892) [2] [3] [4] in Illinois and was the first company to (successfully) [5] release a 10-key adding machine. The machine was a breakthrough for its time because it dramatically modernized computing.
