Abstract
Abstract A slip clutch of the friction type is described for interposition between a rotary shaft and a driven or driving element on the shaft, such as a gear, cam, pulley, crank or the like, the slip clutch including a split sleeve in engagement with the element or the shaft but retained against movement by a key carried in a keyway on the shaft or in the element, a split tolerance ring being interposed between the split retainer ring and the shaft or the element and retained against rotation with respect to each other and to the shaft or the element in the shaft by the key. The gear, cam, pulley and the like is retained against longitudinal movement along the shaft in any desired manner such as by a shoulder on the shaft and a split retainer ring in a groove on the shaft or by a pair of spaced retainer rings in grooves on the shaft.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
In combination, a rotary shaft member, a member mounted on said shaft for movement therewith, and a slip clutch interposed between said members and comprising a split sleeve in surrounding relation to said shaft and in frictional engagement with one of said members, a split band disposed between said sleeve and one of said members and having a plurality of resilient corrugations for providing a spring force to maintain said frictional engagement, and means for preventing relative rotational movement of said split sleeve and said split band with respect to each other and with respect to one of said members.
Claim 2
Dependent Claim
