    Patent number: 3949848
    Abstract: A pair of bi-directional roller clutches are connected through outer races to separate gearsets and share a common inner race connected to a driven shaft. A shifting sleeve is slidably mounted on the common inner race and is selectively engagable with the retainers of the roller clutches, thereby locking the rollers of the engaged clutch in the freewheeling mode and releasing the rollers of the other clutch, allowing that clutch to drive through its associated gearset.
