Abstract
The invention is concerned with provision of a power take-off from a friction clutch without altering the fundamental design of the clutch itself. The clutch comprises a cover member, a pressure plate and a diaphragm spring having an outer belville portion and inwardly directed fingers. The diaphragm spring urges the pressure plate against driven plate to provide a primary drive. The diaphragm spring is located on the cover member by tabs passing through mounting apertures at roots of the fingers and bent over to hold the spring in position. A power take-off drive member incorporates tabs engaged in the mounting apertures and bent over to locate the power take-off drive member with respect to the cover.
