Gear 1 rotates about fixed axis A and meshes with gear 7 which rotates about fixed axis B. Eccentric 2 is rigidly attached to (or integral with) gear 1 and is connected by a turning pair in the form of collar a to link 3. Link 3 is connected by turning pair C to slider 4 which moves in fixed guide b. Link 5 is connected by turning pair D to slider 4 and by a sliding pair to slider 9 which moves along slot e of link 5. Roll 10 of link 5 slides along slot d of face cam 6 which is rigidly attached to (or integral with) gear 7. Slider 9 is connected by turning pair E to bar 8 which moves in fixed guide f. When gear 1 rotates, bar 8 reciprocates. The required kind of motion of bar 8 can be obtained by properly designing the shape of slot d of cam 6.
