DEFINITION

Classification: 192/70.18

(under subclass 70.17) Device wherein said means comprises a link or strap having two ends, one end of which is attached to a clutch-element (or to an equivalent rotating member such as a pressure plate or flywheel) at a point on the clutch-element radially spaced from the axis of rotation thereof, and the other end of which link is attached to a driving or driven shaft (or to an equivalent rotating member integral therewith) at a point on the shaft radially spaced from the axis of rotation thereof and angularly spaced from the first-mentioned attachment.

(1) Note. The attachment at either end of the link may take the form of a pivot pin passing through a hole in the link or a resilient connection between the link and the clutch-element or its supporting shaft. The necessary requirement for this subclass (70.18) is not the form of attachment, but rather that the link extend between the two rotating parts (i.e., the clutch-element and its supporting

shaft) as if the link were a chordal link intersecting circles of revolution traced by link-connecting parts of the clutch-element and its shaft.
