Abstract
Two shafts rotatable about the same axis and having hubs are connected to each other by a transverse beam. One end of the beam is pivotally connected to one hub and the other end of the beam is pivotally connected to the other hub. Two roller followers are mounted to the beam with one follower located on each side of the beam's mid-point. The followers are guided by the interior surface of a closed path guide cam. In operation, the beam first pivots about the axis of one follower and then pivots about the axis of the other follower in a repetitive alternating sequence. For a given hub, the distance between the beam's pivot point and the hub connection changes each time the pivot point moves from one follower axis to the other. This causes one hub to alternately rotate at speeds which are relatively faster than, and then relatively slower than, the rotational speed of the other hub.
