Link 1 has circular guide a with its centre at point 0. Link 3 is connected by a turning pair to link 2 which is designed as a prismatic slider fitting in guide a. When bracket 4 is put into various positions by turning it about fixed axis A and clamping it, rotation can be transmitted from link 1 through link 2 to link 3, rotating about fixed axis B, under the condition that the axes of all the turning pairs and of the circular guide intersect at single point 0. The mechanism transmits rotation from shaft 1 to shaf t 3 at various angles of intersection of their axes at point 0.
