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