291. Keller, E. A. Jan. 5. Brakes, back-pedalling. The lower portion of the chain a' passes over a toothed wheel c carried by one arm of a bell-crank lever d, the other arm e of which carries the brake shoe h. The lever d is pivoted to the frame by an arm g as shown. A spring i normally presses the brake out of action. On back-pedalling, the lower portion of the chain tightens, forces down the arm d of the lever, and applies the brake.
