Crank 1, rotating about fixed axis A, drives link 6 through intermediate link 5. Link 6 is connected by turning pair B to link 5 and by sliding pair C to link 2 which slides in fixed guides a-a. Pin b of link 6 slides in slot d of link 4 which turns about fixed axis D. Link 7 is connected by turning pairs E and F to link 4 and slider 8 which moves in fixed guide slot f. Slider 8 is connected by a screw pair to link 3. When crank 1 rotates, link 2 reciprocates. The stroke of link 2 can be adjusted by changing the position of link 4. This is done by turning screw 3. The stroke can be changed in operation.
