Link 1 is connected by turning pair A to the fixed link and by screw pair B to slider 2 which moves along fixed guides p-p. Link 2 has guides d-d along which bar 3 slides. Bar 3 carries pin f which slides along slot a-a. When link 1 is rotated, slider 2, together with bar 3, moves along axis x-x of link 1. Owing to slot a-a in plate e, bar 3 has a sliding motion perpendicular to the axis of link 1. The law of motion of bar 3 can be varied by adjusting plate e and clamping it with screws h and m in various positions.
