Slider 1 moves along fixed guides q-q. Rigidly secured to slider 1 is cross-piece p along which slider 2 moves. Link 3 is connected by turning pair K to slider 2 and by sliding pairs to sliders 4 and 5. Slider 5 is connected by turning pair C to slider 1. Slider 4 turns about fixed axis A. When slider 1 moves along guides q-q, point K describes a hyperbola with the equation x²-xy*tan(ϕ)+(k*tan(ϕ)-a)x+ak*tan(ϕ)=0 where a = distance between point A and the axis of fixed guides q-q, k = C͞B, ϕ = angle between the axes of guides q-q and p-p.
