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 X-shaped slider 4 which has guides making the angle 90°γ with each other. Slider 4 moves along fixed guides p-p, whose axis makes angle α with axis Ax, and is connected by a sliding pair to link 6. Link 6 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)-tan(γ), f=(m*tan(γ)-n*tan(α))/2, g=-m/2, m and n = constant dimensions of the mechanism.
