Abstract: A clutch for use in an open faced fishing reel that when engaged operates as a conventional one-way clutch, with the pins or needles rolling with the shaft and allowing for movement in one direction but binding the shaft to an outer fixed surface, prohibiting rotation, when the shaft is urged in the opposite direction, but when is disengaged, is switchable from one-way action to freewheel action i.e. shaft motion allowed in both directions by separating the outer binding surface from the main housing of the clutch, allowing it to move radially and allow the surface required to bind the shaft to move away from contact with the pins and shaft, thereby allowing the shaft to freewheel. The clutch is particularly well suited for use in a fishing reel.

Abstract: An improved ratchet screwdrivers utilizes a curved spring to encircle two engaging gear blocks at the ratchet gear portion of the transmission shaft, and then a rotating coupling is used to shift the position of the slide in order to designate the operating direction of the transmission shaft. It indicates that when a certain side of the engaging gear block needs to be activated for locking purpose, it needs to disengage the engaging gear block from the ratchet gear part so that its engaging function is disabled. As a result, because one side of the coiled spring is compressed by the external force, the other will be further compressed to the engaging gear block that has not shifted due to its retaining force, thus a more powerful driving force is generated.

Abstract: An active multi-mode overrunning clutch assembly includes concentric inner and outer members and a plurality of opposed pairs of clutch pawls operably disposed between the members. The clutch pawls are biased radially outwardly and include recessed portions and raised lands which cooperate with an axially translatable circumferential control sleeve. The control sleeve can be translated to select various combinations of active (engaged) or inactive (retracted) pawls to effect four distinct operational modes: fully engaged, i.e., locked in both directions, drive and overrunning in a first direction, drive and overrunning in the reverse direction and fully disengaged, i.e., released or inactive. The active multi-mode overrunning clutch assembly finds particular application in transfer cases of four wheel drive vehicles.

Abstract: A switchable ratchet freewheel, under load, for multiple-gear hubs on bicycles includes a bolted pawl, a drive, a switch bush, as well as a switch ring. The switch ring, which has a positive-fit connection to the pawl, can either be lifted by a bulge on the switch bush, which acts in concert with an incline on a switch nose, provided that a small or no turning moment is conveyed, or by recesses with end faces and timing edges, which act in concert with a run-up incline on the recesses, whereby the recess enters into a short positive-fit connection with the segment of the switch nose that faces radially inward, provided that higher turning moments are present. In case the pawl is not lifted immediately, by means of the bulge acting in concert with the incline, this results in the positive fit of the recess with the switch nose, which reliably disengages the pawl bond when the run-up incline acts in concert with the timing edge.

Abstract: A rotation transmission device has a driving member and a driven member rotatably mounted one inside the other. A plurality of engaging elements are mounted between the driving member and the driven member so as to engage with the driving member and the driven member when the driving member and the driven member rotate relative to each other in either direction.

A turning force imparting mechanism is coupled to the cage for moving the engaging elements to an engageable position by turning the cage in one direction relative to the driving member, and a locking mechanism is provided between the cage and the driven member for detachably coupling the cage to the driven member and remote-controlled through a cable connected to the locking mechanism and extending out of the rotation transmission device.

Abstract: A transfer case for a vehicle having two output shafts, a gear reduction assembly, a coupling mechanism and an overrunning roller clutch for selectively producing driving of one shaft only or both shafts concurrently. The coupling mechanism selectively couples one output shaft to either (1) an input shaft, (2) the gear reduction assembly, or (3) a neutral position. The overrunning clutch has an inner race, an outer race, and rollers located between the races. Drag shoes are positioned to frictionally slide on a drag surface of a selectively grounded member to retard the rollers. A resilient band urges the drag shoes against the drag surface. When the drag shoes rotate at a sufficient speed they disengage from the drag surface so as to provide no force to retard the rollers. When the ground member is grounded it provides the drag surface for the drag shoes. When the ground member is ungrounded it is free to rotate and the drag shoes do not provide a drag force to bias the rollers.
