Slider 1 moves along fixed guide T-T whose axis is parallel to axis Oy. Slider 1 is connected by turning pair B to slider 2 and by a sliding pair to cross-shaped slider 3 which has guides perpendicular to each other. Slider 7 moves along fixed guides t-t whose axis is parallel to axis Oy. Slider 7 is connected by turning pair A to bent link 8 having angle AFf equal to 90°. Cross-piece Ad of slider 7 has its axis parallel to axis 0x and is connected by a sliding pair to slider 6. Sliders 6 and 5 are connected together by turning pair C. Arm Ff of link 8 is connected by a sliding pair to slider 9 which turns about fixed axis 0. Cross-piece 0n of slider '5 is connected by sliding pairs to sliders 5 and 2. Link 4 is connected by turning pair C to sliders 5 and 6, and by a sliding pair to slider 3. When slider 1 moves along guides r-r, point C of slider 6 describes parabola s-s, and point D of slider 3 describes a fourth-order hyperbola having three branches. The equation of hyperbola q-q is x²y²-2pa²x=a²p² where a and p are constant dimensions of the mechanism.
