Link 1 rotates about fixed axis A and is connected by turning pair B to segment gear 2 which meshes with segment gear 3, rotating freely about axis A. Segment gear 3 has a crank with slot a along which axis D can be adjusted. Connecting rod 6 is connected by turning pairs D and E to gear 3 and to link 7 which turns about fixed axis F. When roller 4, carried by segment gear 2, reaches a portion St of internal fixed cam 5, segment gear 2 is turned about axis B and it turns segment gear 3 with its crank. This transmits accelerated motion to connecting rod 6 and link 7.
