Eccentrically mounted circular gear 1 rotates about fixed axis A and meshes with gear 5 which rotates about axis D of slider 4. Slider 4 moves along guide a in the base. Gear 1 is connected by turning pair B to link 3 which has collar b connected by a turning pair to gear 5. Gear 5 is connected by turning pair C to slider 6 which moves along slot d of slider 2. Slider 2 moves in fixed guides f-f. The dimensions of the links comply with the conditions: r₅=2r₁, A͞B=0.125r₁, B͞D=3r₁ and D͞C=r₁. Point C describes curve q. When gear 1 rotates at uniform velocity, slider 2 travels with approximately uniform velocity in its forward stroke. The angular velocities ω₁, ω₅ and ω₃ of gears 1 and 5 and connecting rod 3 are related by the equation ω₅=(3ω₃-ω₁)/2. The angular velocity ω₃ is determined on the basis of the given dimensions of slider-crank linkage ABD.
