Patent for a simple and inexpensive clutch used for transmitting power. The clutch has "independent rotable disks that act on peripheral eccentric proportions, which are so arranged that the said disk will be held free from contact with the drive-shaft and the entire bearing of the clutch mechanism thrown on the grip members, whereby the shaft-apertures in the disks can be made sufficiently large to overcome any irregularity of the bearing-faces of the internal cam portions and obviating the necessity of providing outside collars" (lines 17-27).
