The lengths of links 1 and 2 are equal, respectively, to those of links 4 and 3. Link 1, rotating about fixed axis A, is connected by turning pair C to link 2. Link 3 is connected by spherical pair E to link 2 and by turning pair D to link 4 which rotates about fixed axis B. The mechanism transmits rotation between any two arbitrarily located axes A and B.
