22,441. Driver, J. Nov. 7. Brakes for cycles and other road vehicles. Brake blocks h, Fig. 1, adapted to engage the rim, are secured by bolts h1 to plates g1 pivoted at g between ears f formed on slides e, and adapted to be secured at any distance apart by a bolt i engaging in a slot g11. The slides e, which slide in clips b secured to the forks, are supported by ears e', drawn downwards by springs f1 connecting them to lugs formed on the clips b, and are actuated so as to apply the brake by a cord j passing round a pulley j1 mounted in a block j11 carrying a pulley k1 actuated by a looped cord, which is passed through flexible guidetubes k11 secured by clips to the frame, and is connected at its end either to an ordinary hand-lever or to the arrangement shown in Figs. 6 and 7 and comprising a plate m clipped on the handle-bar and formed with an axle m11 carrying a pulley n', round which the cord k is wound, the end being secured to a lug n11. A ratchet-wheel n, secured to the pulley n1, is actuated so as to apply the brake by a pivoted thumb-lever o. The brake is held in operation by a spring or other pawl p, which can be released by returning the lever o to its original position and then lifting it so as to raise a lug p1 formed on the pawl. A cover q resembling a bell dome is secured over the plate m as shown. The tendency of the flexible tubes k11 to straighten assists in keeping the cord taut.
