Abstract
The device comprises an oval cam 10 and two toothed rings 3, 4 which are coaxial with the cam and have the same diameter but different numbers of teeth, one of the rings being connected to one of the elements to be adjusted while the other ring is connected to the other element, a flexible set of teeth 16 having a number of teeth less than the number of teeth of the rings, and a flexible ring 30. The ring 30 has a smooth surface in facing relation to the cam 10 and a set of teeth 32 on the opposite side of the ring. The ring is urged by the cam 10 into engagement with the flexible set of teeth 16 and the latter is urged toward the teeth of the rings 3, 4.
