Babbage was an English mathematician and inventor; he invented the cowcatcher, reformed the British postal system, and was a pioneer in In 1775 the 'younger machine' was sent to the University of Göttingen for repair, and was forgotten. In this way, the operand can be multiplied by as large a number as desired, although the result is limited by the capacity of the accumulator. The result appears in the 16 windows on the rear accumulator section. A survey has shown that Brits use more than 50 different words and phrases to describe the remote control they use for their television. Accordingly, he eventually designed an entirely new machine called the Stepped Reckoner; it used his Leibniz wheels, was the first two-motion calculator, the first to use cursors (creating a memory of the first operand) and the first to have a movable carriage.

It was a cylinder with nine bar-shaped teeth of different lengths, which increased in equal steps around the drum. “Stepped Reckoner,” a calculator using a stepped cylindrical gear. The Stepped Reckoner, invented by Gottfried Wilhelm Leibniz, completed in 1694. easy, fast, and reliable. The Stepped Reckoner The Leibniz calculator, which he called the Stepped Reckoner , was based on a new mechanical feature, the stepped drum or Leibniz Wheel . Some sources, such as the drawing to the right, show a 12-digit version. The number of additions (or subtractions) is controlled by the multiplier dial. Two prototypes were built, only one survived.

[2], Its intricate precision gearwork, however, was somewhat beyond the fabrication technology of the time; mechanical problems, in addition to a design flaw in the carry mechanism, prevented the machines from working reliably.[3][4]. Other copies or versions of these images might be available elsewhere. Joseph-Marie Jacquard Joseph-Marie Jacquard was a weaver. It was made famous by Thomas de Colmar when he used it, a century and a half later, in his Arithmometer, the first mass-produced calculating machine. The input section has 8 dials with knobs to set the operand number, a telephone-like dial to the right to set the multiplier digit, and a crank on the front to perform the calculation. The basic operation performed is to add (or subtract) the operand number to the accumulator register, as many times as desired (to subtract, the operating crank is turned in the opposite direction). a. https://www.sciencephoto.com/media/506315/view/leibniz-s-calculating-machine The name comes from the translation of the German term for its operating mechanism, Staffelwalze, meaning "stepped drum".It was the first calculator that could perform all four arithmetic operations.

He concentrated on expanding Pascal's mechanism so it could multiply and divide. The input section is moved with the end crank until the lefthand digits of the two numbers line up. It operates like a telephone dial, with ten holes in its circumference numbered 0–9. His so-called older machine was built between 1686 and 1694. The above two steps are repeated to get each digit of the quotient, until the input carriage reaches the right end of the accumulator.
