Links 1 and 2 slide in fixed guides q and p whose axes are parallel to each other. Link 3 turns about fixed axis A. Pins d and e of links 2 and 1 slide along slots a and b of link 3. The mechanism is intended for the mathematical operation y = kx, where y is the displacement of link 1, x is the displacement of link 2 and k=a/b is the ratio of constant dimensions of the mechanism.
