Crank 1, rotating about fixed axis A, is connected by turning pair B to slider 2 which moves along link 3. Link 3 oscillates about fixed axis C. By means of intermediate slider 4, moving in a guiding slot of slider 5, link 3 reciprocates slider 5. Slider 5 travels with different kinds of motion in its forward and return strokes. For rotat ion of crank 1 at uniform velocity, the time ratio of the forward to the return stroke is k=(π/(arccos(A͞B/A͞C)))-1.
