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.

He was awarded the Franklin Institute's John Scott Legacy Medal shortly before his death. [1] He was posthumously inducted into the National Inventors Hall of Fame. [2]
The Comptometer was the first commercially successful key-driven mechanical calculator, patented in the United States by Dorr Felt in 1887.. A key-driven calculator is extremely fast because each key adds or subtracts its value to the accumulator as soon as it is pressed and a skilled operator can enter all of the digits of a number simultaneously, using as many fingers as required, making ...
