Cam 1 rotates about fixed axis A and its profile is designed as an eccentrically mounted c ircular member with ridge a. Follower 3 reciprocates in fixed guide B and carries rollers 2 and 4 which roll along the inner and outer surfaces of ridge a. The displacement of follower 3 from its extreme right-hand position is s₃=e(1+cos(φ))r[1-sqrt(1-(e/r)²sin²(φ))] where e=0͞A is the eccentricity of cam 1, r is the radius of the theoretical, or pitch, curve of the cam and φ is its angle of rotation.
