Invention And History Of The Adding Machine

Invention And History Of The Adding Machine, is going to be today’s post here in Discover My Inventions, an adding machine was a mechanical built calculator, that was used for offices such as banks finance companies etc., the adding machine eventually faded away when the calculators were developed and then later the personal computer which took the place of the adding machine in the mid-1980s.

I take a great deal of interest in history and inventions of all kinds, and I can remember dealing with banks and finance companies to even local grocery stores when they will be using the adding machine, the adding machine was also a device used for home office use as well for people who worked from out of their homes, and I can remember when the handheld calculator come out which was digital a lot of people referred to them as a handheld adding machine.


It was Blaise Pascal and Wilhelm Schickard that was the two original inventors of the mechanical calculator in 1642; For Pascal this was an adding machine that could perform additions and subtractions directly and multiplication and divisions by repetitions, whilst Schickard’s machine, invented several decades earlier was less functionally efficient but was supported by a mechanised form of multiplication tables.

These two were followed by a string of inventors and inventions leading to those of Thomas de Colmar who launched the mechanical calculator industry in 1851 when he released his simplified arithmometer (it took him thirty years to refine his machine, patented in 1820, into a simpler and more reliable form). However, they did not gain widespread use until Dorr E.

Felt started manufacturing his comptometer (1887) and Burroughs started the commercialization of differently conceived adding machines (1892, an adding machine was 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.

Adding machines were ubiquitous office equipment until they were phased out in favor of calculators in the 1970s and by personal computers beginning in about 1985. The older adding machines were rarely seen in American office settings by the year 2000.
