Link 2, designed as a bent lever, turns about fixed axis 0. One arm of link 2 moves in slider 4 and the other arm in slider 3. Slider 4 is connected by turning pair K to link 5, and slider 3 by turning pair B to cross-shaped slider 1 which has guides perpendicular to each other. Slider 1 moves along fixed guides r. Link 5 is connected by a sliding pair to slider 1 . When slider 1 moves along axis z-z of guides r, point K describes a parabola with the equation y²=2px , where 2p is the distance from axis y to axis z-z.
