Meshing gears 1 and 2 rotate about fixed axes A and B. Cranks a and b can be rigidly attached to gears 1 and 2 at various angles to the line joining points A and B. Connecting rods 3 and 4 are connected by turning pairs C and D to gears 1 and 2, and by turning pairs E and F to crossbeam 5 which, in turn, is connected by turning pair K to slider 6. Slider 6 moves along guides d-d. The lengths of the links comply with the conditions: A͞C=B͞D, C͞E=D͞F and K͞E=K͞F. The required stroke of slider 6 can be obtained by changing the sizes of gears 1 and 2, and by clamping cranks a and b at various angles to line AB.
