1918. Player, J. H. Jan. 27. Clutches; brakes. -Relates to backpedalling brakes for bicycles, tricycles, &c. A collar B mounted on the hub carries a spring pawl b<2> which engages ratchet teeth s<1> on the inside of the chainwheel S during forward driving. The chain-wheel is provided with a notched flange s<2>, which engages a hook f<2> on the end of a brake band F fixed to a flanged disc E fixed to the axle. On back-pedalling the band is tightened on a drum D mounted on the hub. The collar B and drum D are formed with threads of opposite direction, so that the drum acts as a lock-nut. In a modification, the disc E is arranged eccentrically to the drum D, and the brake consists of a wedge-shaped piece which is forced into the space between the drum and disc flange.
