The lengths of the links comply with the conditions: F͞G=K͞H and F͞K=G͞H. Thus links 4, 5, 6 and 7 forms a parallel-crank linkage. Links 1, 2 and 3 slide in fixed guides A, M and L. Sliders 8, 9 and 10 move along the axes of links 7 and 5, and are connected by turning pairs E, C and B to links 1, 3 and 2. Link 7 turns about fixed axis 0. The lines of motion of links 2 and 3 are perpendicular to each other and pass through point 0. The lines of motion of links 1 and 3 are parallel to each other. When link 1 is displaced a distance x and link 2 a distance y, driven link 3 is displaced by the amount z=xy/k where k is a constant dimension of the mechanism. Thus the mechanism multiplies two independent quantities x and y.
