Abstract
A mechanism to generate a polygonal path such as a square with much greater accuracy than is presently possible. This is accomplished with the use of only circular gears or their equivalent, that is to say, without expensive specially machined parts. The mechanism includes first, second and third rotating members on spaced axes with connecting means between said members and a support frame and an eccentric member mounted on the third rotating member on a fourth axis displaced from the axis of the third rotating member.
