                    | Abstract | An algebraic and suitable methodology is derived in order to calculate, by means  of hand computation, the lengths of the links of planar-four-bar linkages whose a coupler point is able to trace a quasi -circular arc. An algebraic and suitable methodology is derived in order to calculate, by means
 of hand computation, the lengths of the links of planar-four-bar linkages whose
 a coupler point is able to trace a quasi -circular arc. Some examples of these
 devices illustrate the soundness of the procedure.
