Gear 1 rotates about fixed axis A and meshes with gear 2 which rotates about fixed axis B. Gears 1 and 2 have equal pitch radii. Rigidly attached to gear 1 is crank 7 which is connected by turning pair C to link 3. Pin 8 of link 3 slides along slot a of face cam 6 which is rigidly attached to (or integral with) gear 2. Link 3 is connected by turning pair D to link 4 which, in turn, is connected by turning pair E to lever 5. Lever 5 rotates about fixed axis F. When gear 1 rotates, lever 5 has an oscillating motion. The required kind of motion of this lever can be obtained by properly designing the shape of slot a of cam 6.
