Slider 3 turns about fixed axis A. Link 1 is connected by sliding pairs to sliders 3 and 5 and by turning pair B to slider 4 which moves along fixed guides p-p. Link 6 is connected by turning pair C to slider 5 and by a sliding pair to cross-shaped slider 2 which has guides perpendicular to each other. Slider 2 is connected by a sliding pair to extension Ba of slider 4. When point D of slider 2 follows a given curve ϕ(ξ,η)=0 with the coordinates ξ and η, point C of slider 5 traces curve F(x,y)=0 with the coordinates x and y. Coordinates ξ, η, x and y are related by the conditions x=ξ and y=(1/a)ξη where a is a constant dimension of the mechanism. Thus the mechanism converts curve ϕ(ξ,η)=0 into curve F(x, y)=0.
