Abstract
Abstract A clutch mechanism for incorporation in machinery, the clutch being of over running type and comprising a means for transmitting rotational movement between shafts which are axile aligned with each other, the device consisting of a face plate on each end of the shafts; in one form of the invention, one of the face plates having tapered slots each of which contain a ball movable along the slot for engaging the other face plate; and in another form of the invention the peripherial edge of one of the face plates having tapered slots each of which contains a ball and wherein the balls traveling the slots engage an inner cylindrical face carried by the other face plate.

Claim 1
Independent Claim
192 words
In an over running clutch, the combination of a drive shaft and a driven shaft in axial alignment with each other, a face plate rigidly secured on one end of each said shaft, an outer face of each said face plate facing each other in spaced relation, one said face plate having on said outer face a plurality of tapered, straight slots, each said tapered slot having a spherical ball slidable therein, one end of said slots being gradually deeper than the other end thereof so to form said tapered slots, said deeper end of said slots being located relatively nearer to a center axis of said shaft while a shallow opposite end of said slots is located relatively further away from said shaft center axis, each said slot accordingly extending at an angle respective to an imaginary radial line extending from said center axis, whereby a centrifugal force caused by rotation of said shaft will throw said balls toward said slot shallow ends so that said balls frictionally engage the other said face plate, said balls being of a greater diameter than a width of a space between said face plates.
