The lengths of the links comply with the conditions: A͞B=B͞C=B͞M=1, A͞E=0.55, C͞E=1.38, ∠ABM=β=267°, γ=43.5°, M͞D=1.5 and H=1.79. Point M of connecting rod 2 of four-bar linkage EABC describes connecting- rod curve a-a. Link 3 is connected by turning pairs M and D to connecting rod 2 and slider 4 which moves along fixed guides b-b. The time ratio k of the forward to the return stroke of slider 4, at constant angular velocity of crank 1 rotating about fixed axis E, is k≈5/3.
