Link 1 slides in fixed guide p. Link 2 slides in fixed guide q whose axis is perpendicular to that of guide p. Link 3 turns about fixed axis A and has slot d whose axis is parallel to arm AB of link 3. Pin B of link 3 slides along slot f of link 2, and pin E of link 1 slides along slot d of link 3. The mechanism is intended for the mathematical operation xy=ab, where x is the displacement of link 1, y is the displacement of link 2 and a and b are constant dimensions of the mechanism.
