Link 1, rotating about fixed axis A, has pin B which fits into slider 3. Slider 3 moves along movable circular guiding slot a-a of radius BC and with its centre at point C. When link 1 rotates, link 2 reciprocates along axis x-x. The mechanism is equivalent to slider-crank linkage ABC in which A͞B is the crank, B͞C is the connecting rod and link 2 is the slider.
