Abstract
A disc is provided which centers itself on motor shafts that vary somewhat in diameter. The disc is formed of a single sheet of material with a central hole for receiving the shaft and with a group of fingers projecting slightly into the hole to engage a shaft. The fingers are formed by pairs of slots that extend from the edge of the central hole and radially outward to form fingers of considerable length which can be bent out of the plane of the disc to engage shafts of varying size. The radially inner tips of the fingers lie precisely on an imaginary circle which is slightly smaller than the minimum diameter of a shaft, and the fingers deflect uniformly to hold the shaft centered on the axis of the disc.
