Link 1 slides in fixed guides p-p. Link 3 slides in fixed guide q whose axis is perpendicular to that of guides p-p. Bent lever 4 turns about fixed axis A. Link 2 has slot b and slides in fixed giuides m-m. The axis of slot b is perpendicular to that of guides m-m. Link 3 has fork-shaped portion c ending in guides n-n in which link 5 slides. Pin a of link 5 slides simultaneously along slots b and d of links 2 and 4. Pin f of link 1 slides along slot e of link 4. The value of one of the factors, x, is set up by displacing link 1; that of the second factor, y, by displacing link 2. Then link 3 is displaced by the amount z, equal to z=xy/k where k is a constant dimension of the mechanism.
