Four-bar synthesis for the coordination of coupler point displacement with the rotations of both cranks

The correlation of the motion of the coupler point of a four-bar linkage with that of both cranks (partially or fully) is of some practical importance as shown by Hain[1] who gave solutions based either on point position reduction or graphical interpolation. Point position reduction, which loses the infinity of possible designs, and graphical interpolation are replaced in the present paper by improved procedures. © 1975.
