Carrier 1 rotates about fixed axis A and is connected by turning pair C to planet gear 3 which meshes with fixed sun gear 4. Crank 6 is rigidly attached to (or integral with) planet gear 3 and is connected by turning pair B to slider 5. Slider 5 moves along the slot of slotted lever 2 which rotates about axis A. The pitch radius of gear 4 equals R=2r, where r is the pitch radius of planet gear 3. The axis of the slot of lever 2 passes through axis A. If length C͞B of crank 6 is greater than pitch radius r, point B describes prolate epicycloid b-b which is self-intersecting at two points d. To one revolution of carrier 1, link 2 has two short reverse motions when point B travels along the portions of the epicycloid which form loops e.
