Point A of connecting rod 2 of four-bar linkage DEFC describes connecting-rod curve a-a. Slotted link 5 rotates about fixed axis B. Slider 4 moves along the slot of link 5 and is connected by turning pair A to connecting rod 2. Crank 3 is designed as a collar that encircles fixed disk 6 having its centre at point C. During one revolution of crank 3, slotted link 5 makes one complete revolution about centre B with a short dwell in the position where point A of connecting rod 2 reaches point A' of its path. Besides, when point A approaches position A' , slotted link 5 has a small angular motion in the opposite direction. After this it renews its motion in the previous direction.
