ABSTRACT:
A cam system capable of converting a simple motion into a more complex motion contains, in combination, an elastomeric guide bearing and a shaped rod lodged therein, the bearing being held by a member allowing it to assume a proper orientation, either the bearing-holding member or the shaped rod being subjected to the input motion, so that the shaped rod and the guide bearing move relative to each other. Either the moving member or the stationary member is constrained in that it has only two degrees of freedom to rotate. Any moving point on the moving member can be made to perform useful work while it moves in a more complex pattern. A representative embodiment will convert a one-dimensional, sliding motion or a circular motion into a three-dimensional motion, the moving end of the moving member having attached thereto a spray-paint nozzle, which sprays paint in a three-dimensional pattern.
