The mechanism is used to multiply two quantities, one being a complex function. Cam 1 rotates about fixed axis A-A and, through roller 4, reciprocates follower 5 in fixed guide B. Follower 5 carries roller 7 which rolls a long slot a of link 6. Link 6 is connected by turning pair C to slide 3 which moves along fixed guides D-D. Slide 2 moves along fixed guides E-E an carries roller 8 which rolls along slot a of link 6. Displacement s₅ of follower 5 is a complex function, s₅=f(φ₁), of the angle of rotation φ₁ of cam 1. When cam 1 is rotated through angle φ₁ and slide 2 is moved the distance s₂ slide 3 is displaced a distance equal to s₃=s₂*((k-f(φ₁))/f(φ₁)) where k is the constant distance shown.
