Two meshing spur gears 1 and 4 rotate about fixed axes A and B. Connecting rod 8 is connected by turning pairs C and E to gear 1 and to carriage 3 whose wheels 9 roll along fixed horizontal plane a. Two identical pulleys 6 and 7 rotate freely about axes E and F of carriage 3. Connecting rod 5 is connected by turning pairs D and H to gear 4 and to flexible link 2 which runs over pulleys 6 and 7. When gear 1 rotates continuously in one direction, carriage 3 reciprocates along plane a and flexible link 2 has a complex motion consisting of reciprocation with carriage 3 and motion with respect to carriage 3 caused by connecting rod 5 and gear 4.
