Circular slotted link 4 turns about fixed axis A and is connected by a sliding pair to slider 5 which moves along the slot of link 4. Link 4 is connected by turning pair B to link 6. Slider 5 is connected by a turning pair to link 7. Link 1 is driven by a system of links 9, 6, 4, 5 and 7 along one kinematic train and a system of links 9, 10, 11, 12 and 8 along another kinematic train. Link 1 is connected by turning pair C to link 8. The required stroke of link 1 is obtained by setting lever 2 in the proper position. Link 3t is then stationary and link 13 turns about axis D.
