  • Coaster brake for bicycle with derailleur speed change mechanism
    Patent number: 4093261
    Abstract: A chain seizing device responds to reverse movement of the driving chain to declutch the wheel hub from the multiple drive sprocket and apply the coaster brake to the wheel hub. Forward rotation of the sprocket moves a clutch member axially in one direction to release the brake and engage the clutch. Reverse rotation of the sprocket shifts the clutch member in the opposite direction to disengage the clutch and apply the brake. The sprocket is reversed by an arm on the chain seizing device acting through a pawl engagable with the sprocket.
