A tool comprising a stand normally resting on 3 feet. Mounted on the stand is an arbor with a plate divided into equally spaced points in several concentric rows for the different divisions of the wheel. Daniel Jean-Richard is credited as the maker of the first wheel cutting engine to have appeared in Switzerland, having never before set eyes on anything similar. He was told by a stranger that such a machine could be found in Geneva, and set off to investigate. The mystery surrounding this meant that his journey was wasted, but he saw the cut wheels and understood that the operation necessarily involved a rotating cutter and a numbered plate to determine the number of the teeth and to space them at perfect intervals.
