Sliding link 1 turns about fixed axis 0. Slider 2, connected by a sliding pair to slider 4, moves along the axis of sliding link 1. Slider 4 is connected by turning pair A to link 5 which reciprocates in fixed guides q-q. Link 5 is designed as a cross-shaped lever with one arm moving in slider 3. Slider 3 is connected by turning pair C to slider 2. When crank 1 turns about axis 0 , point C describes parabola H with the equation y²=ax, where a is a constant dimension of the mechanism.
