Link 1 has two circular guides a. Link 3 has fork b at its end. Link 2 is designed as two separate prismatic sliders fitting in guides 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 to link 3 under the condition that the axes of all the turning pairs and of the circular guides intersect at a single point . The mechanism transmi ts rotation from shaft 1 to shaft 3 at various angles of intersection of their axes at a constant point.
