Abstract
Abstract In a roller clutch assembly including the conventional crankshaft-cam-flywheel arrangement wherein rotation of the flywheel ring may be transmitted to the cam through engaged drive rollers, the improvement comprising forming slots in the cage retainer walls to receive flexible tubing for each drive roller, whereby when the roller clutch is brought to the actuated position each drive roller will be in resilient contact with its corresponding piece of tubing such that rotation is transmitted from the flywheel ring to the cam through all of the drive rollers, and wherein in disengaged position the cage retainer wall, through direct contact between the tubing and each individual roller urges the rollers against the next retainer arcuate wall and away from the rotating ring.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
196 words
In a roller clutch assembly, including a cam and an annularly disposed drive ring, drive rollers interposed between the cam and the ring, and a retainer provided to coact with said cam to urge the rollers into or out of driving position with respect to the ring, depending upon the action of said cam, the improvement comprising providing the retainer with first and second walls, forming slots in the retainer first walls with said slots running generally parallel to the axis of said rollers, said slots receiving resilient tubing whereby the axis of said tubing is generally perpendicular to the movement of said drive rollers when said rollers are brought from disengaged to driving position by said retainer such that said tubing in each of said slots is contacted by a roller as the roller is urged by said retainer into driving engagement with said drive ring, said retainer second wall having an arcuate shape so that when the roller cage is moved to disengaged position, said retainer arcuate wall urges said roller against said tubing but away from said drive ring to maintain a disengaged condition until said retainer is again moved into driving engagement.
Claim 2
Dependent Claim
