ABSTRACT:
A two-way free-wheeling clutch is formed between a drive shaft and a driven shaft concentric with and encircling at least a portion of the drive shaft that is formed by axially extending substantially chord forming portions. The chord forming portions cooperate with circular bearings interposed between the portions and a circumferential surface of the encircling portion of the driven shaft to drive the driven shaft from the drive shaft. Drive of the driven shaft by the drive shaft is obtained by relatively positioning the bearings and the portions so the bearings are toward the radial extremities of their respective chord portions a driving wedge is formed with the inner circumferential surface of the driven shaft. When the portions and the bearings are shifted to relatively position the bearings closer to the centre of the chord forming portions i.e. minimum radial position on the chord free rotation of the driven shaft freewheeling of the driven shaft is permitted. Circumferential movement of the circular bearings is impeded so that the relative positions of the circular bearings and their respective portions automatically change with a change in direction of rotation of the drive shaft or by simply stopping rotation of the drive shaft.
