Cylinder cam 1 rotates about fixed axis A-A and its ridge is designed as a nonplanar slanled washer. Follower 2 oscillates about fixed axis B-B and carries two rollers, 3 and 4, which roll along the side surfaces of the ridge of cam 1. Axes C of rotation of rollers 3 and 4 intersect and are perpendicular to axis A-A. Axes A-A and B-B are perpendicular to each other. Positive motion is achieved by the two rollers, 3 and 4.
