Gear 1 rotates about fixed axis A and meshes with gear 5 which rotates about axis B. Gear 5 meshes with gear 2 which rotates about eccentrically located axis D. Link 6 turns about axis A and is connected by turning pair B to link 7 which, in turn, is connected by turning pair C to gear 2. Link 4 is connected by turning pairs K and E to gear 2 and to slay 3 which turns about fixed axis F. When driving gear 1 rotates at uniform velocity, gear 2 rotates with nonuniform velocity and slay 3 oscillates with the required type of motion.
