Abstract: In the paper, three cells are considered, namely, Peaucellier’s cell, Kempe’s cell and a new one which is derived from Kempe’s cell. Each of them gives rise to straight-line mechanisms of the ...

Abstract: The paper describes the equivalent of Roberts’ law for Watt-1 mechanisms. It is shown that two floating links of the mechanism may be in turn generated by more than one mechanism of this ...

Abstract: Application of the theory on cognate six-bars of Watt’s type makes it possible to link the well-known inversion mechanisms through mechanical cognation. It is proved that the inversors of ...

Abstract: In this paper a geometrical solution is given to the problem of finding four-bar linkages having 5 given coupler-point positions coordinated with 4 given crank angles. It may also be possible ...

Abstract: A new method has been developed to derive the 10 Hackmüller conics going through the four Burmester points of five positions of a moving plane, and each going through another virtual center ...

Abstract: Double-cranks containing a Chebyshev-dyad are investigated for their use as a straight-line mechanism. The three available design degrees of freedom have been used for the optimization of the ...

Abstract: The complete pole configuration of a planar n-link mechanism having one instantaneous degree of mobility, possesses (3n−4)/2 in dependent poles determining (n−2)2 /2 remaining poles of the ...
