Slider 1, moving along fixed guides q-q, is connected by turning pair D to slider 4 and by a sliding pair to link 5 . Link 5 is connected by turning pair B to link 3 which has the form of bent lever nBm. Arm Bm of link 3 moves in slider 4, and arm Bn in slider 2 which turns about fixed axis A. When slider 1 moves along guides q-q, point B describes hyperbola p-p with the equation y²*sin²(β)+xy*sin(β-α)-y[e*sin(β)+d*sin(β+α)]-x[d*sin(β)+e*sin(β-α)]=0, where d and e = constant dimensions of the mechanism, α and β = constant angles complying with the condition α≠β. If angle α=β then point B describes a parabola.
