Abstract: A dual roller clutch assembly with cages and cam races that cooperate to assure both that the cages are properly installed to the cam races and that the cam races are properly assembled relative to each other. The same structure also retains the cam races and cages together as a secure subassembly. Stops molded to the cages prevent incorrect installation of the cages to the cam races by blocking axial insertion in the incorrect direction. Locating notches in selected cam race end faces prevent incorrect relative positioning of the cam race-roller cage subassemblies by engaging a two-sided rib on the cages only when the cam races are properly oriented. The same two-sided rib retains the cam races axially together.

Abstract: An improved twist lock installed roller clutch cage uses axially central ribs on the bottom of the journal blocks that move into matching grooves in the bearing surfaces of the cam race when the cage is twisted into place. This retains the cage axially to the cam race, but leaves the end faces of the cam race totally unobstructed.

Abstract: A self seating roller clutch cage is molded with lead in ramps next to its cam hook engaging reacting faces, so that the cage need only be partially registered with the cam race before it is pushed in. Pushing the cage straight in alone acts to twist the cage to the point where the reaction faces and cam hooks are fully aligned.

Abstract: Roller control cars are securely retained to a cage by using the crush length of the roller energizing springs to prevent guide tabs of the cars from backing out of guide tracks on the cage.

Abstract: A ratchet device is provided in a roller clutch that acts between the ends of the rollers so as to allow the rollers to turn only in the wind up direction, thereby allowing quick change from overrun to lock up, but preventing roller spin and cam wear curing overrun.

Abstract: A roller clutch cage combines the advantages of easily molded plastic cross bars with the strength of steel side rails, but is assembled without the need for any rivets or the deformation of any metal part. Cooperating flexible arms and fulcrum surfaces molded to each end of each plastic cross bar tightly grip the side rails, providing a very rigid structure.

Abstract: A thrust type one-way roller clutch includes a means to assure that the centrifugal force of rotation does not destabilize the ready position of the rollers. The cam ramp surfaces are angularly offset from a radial line in a direction opposite to the allowed direction of relative race rotation. The energizing springs bias the rollers toward a ready position of light engagement with the cam ramp surfaces, thus maintaining the rollers with their individual axes similarly angularly offset. As a consequence, the centrifugal force of rotation will cause the rollers to move in a direction toward ready position only.

Abstract: An overrunning roller clutch with a double row of rollers has an increased load bearing capacity, substantially equivalent to that of a clutch having a single row of rollers of double the length, but without the end loading problems that could occur from single, longer rollers. The clutch uses specially designed unitary energizing springs with resilient elements located by a base of the spring, in cooperation with the cage, so as to act independently on each roller of each pair.

Abstract: A one-way clutch of the type having a spring biased roller engaged with inclined ramps has a roller retention cage with spring mounting blocks mounted thereto by inclined tracks. The spring mounting blocks are movable along the track under the centrifugal force of the over-running clutch to further compress the spring to provide increased energizing force to in turn prevent roller drift along the inclined ramp.

Abstract: A fuel cap assembly has a handgripping cover portion, a threaded closure portion and a ring portion. The ring portion has an inwardly facing lip for axially supporting the closure and a flexible skirt depending from the inwardly facing lip and terminating in an outwardly facing lip. The inwardly facing lip flexes outwardly during assembly of the closure into the ring and the skirt flexes inwardly during assembly of the ring and closure into the cover. An annular groove is formed in the cover at a location aligned with the outwardly facing lip such that the skirt can assume its unflexed position and thereby secure the fuel cap assembly.

Abstract: A fuel cap has a locking mechanism for preventing unauthorized removal of the fuel cap from the fuel fill tube. The lock mechanism includes a cam structure which is operable to provide a selective drive connection, depending upon the condition of the lock mechanism, between the hand grip portion and the threaded closure portion of the fuel cap during rotation of the hand grip in the cap removal direction. The cam mechanism is operable to provide a drive connection in the cap insertion direction regardless of the condition of the lock mechanism.
