Continuous rotation of a driving element 1 produces in a driven element 6 a cycle of motion including part at constant speed when a gear segment 5, 51 meshes with a gear segment 13, 131, 1311 and a portion at variable speed when roller cam followers 8, 81, 811, 9, 91, 911 on the element 6 follow cam surfaces 3, 31, 4, 41 on the element 1, each cam surface being shaped to produce a smooth transition from the gear teeth drive at its start to the gear teeth drive at its finish via a desired motion (e.g. a pause), there being at least one cam follower 8, 81, 811 or 9, 91, 911 and surface 3, 31 or 4, 41 for each direction of rotation. The gear segments 5, 51 may be of different radius in a modified arrangement, Figs. 7 to 9 (not shown).
