Slider 1 moves along fixed guides t-t whose axis is parallel to axis Ay. Slider 1 is connected by turning pair B to slider 3. Cross-piece Bb of slider 1 moves in cross-shaped slider 4 which has guides perpendicular to each other. Slider 4 moves along fixed guides p-p whose axis makes the angle α with axis Ax. Slider 4 is connected by a sliding pair to link 6 which, in turn, is connected by turning pair C to slider 5 . Link 2, turning about fixed axis A, is connected by sliding pairs to sliders 3 and 5 . When slider 1 moves along guides t-t, point C describes parabola q-q with the equation ex²+2fx+2gy=0 where e=tan(α), f=-n*tan(α)/2, g=-m/2, m and n = constant dimensions of the mechanism.
