The mechanism consists of housing 1 with guides a along which sliders 4 move. Semi axes A and B have cranks 3. Connecting rods 2 are connected by turning pairs D and C to sliders 4 and cranks 3, Motion is transmitted from housing 1 through sliders 4, connecting rods 2 and cranks 3 to semi axes A and B which are connected to driving links of the mechanism. When the driving links at the two sides of the housing run at the same speed and in the same direction, there is no relative motion in the slider-crank mechanisms. When the driving links run at different speeds, there is relative rotation between the two cranks 3, and sliders 4 begin to reciprocate along the guides of housing 1.
