Face cam 1 rotates about fixed axis A and has profiled groove a. Cam 1 and round eccentric 2 are keyed to drive shaft 13. Connecting rod 11 has collar b encircling eccentric 2 and is connected by turning pair B to lever 8 which oscillates about fixed axis C. Connecting link 10 is connected by turning pairs D and E to lever 8 and to lever 9 which oscillates about fixed axis H. Bracket 6 is connected by turning pairs F and K to levers 8 and 9, and has guides f-f along which slide 7 reciprocates. Slide 7 has two carriers e which support and transfer the load. Yoke 3 has slot c which slides along shaft 13, and carries roller 12 which rolls and slides along groove a of cam 1. Yoke 3 is connected by turning pair T to l ever 4 which oscillates about fixed axis P and is connected by turning pair R to connecting rod 5. Connecting rod 5 is connected by turning pair S to slide 7. The lengths of the links comply with the conditions: F͞K=C͞H=D͞E, C͞F=H͞K and C͞D=H͞E. Thus links 6, 8, 10 and 9 form a double parallel-crank linkage and, consequently, slide 7 and carriers e have a circular translational motion. When cam 1 and eccentric 2 rotate, carriers e are first raised with the load while a dwell (concentric portion) of cam 1 keeps slide 7 from moving a long bracket 6. When carriers e reach their upper position, cam 1 operates lever 4, moving slide 7 and carriers e with the load to the right. Then eccentric 2 lowers bracket 6 so that the load is deposited at the next station and carriers e clear the bottom of the load. The cycle ends when cam 1 returns slide 7 to its initial position and is under the next load.
