Abstract
The present invention is an improved disc useful as a clutch plate. The disc has a major surface, preferably a flat planar surface, and a hole, having a hole circumference, through the disc at the major surface. Preferably the disc is circular with a concentric hole. The disc further comprises at least one tooth and preferably a plurality of teeth coplanar with the major plane of the disc, and extending from the hole circumference. Each tooth has at least one, and preferably two tooth side edges extending from the hole circumference. Preferably, there are a plurality of the same shaped teeth distributed uniformly along the hole circumference. There is a tab extending at an angle, preferably perpendicular to the major plane from at least part of at least one tooth edge. Preferably a tab extends from each tooth edge.
