Abstract: 23,417. Rudge-Whitworth, Ltd., and Pugh, J. V. Nov. 19. Brakes for motor and other cycles. Relates partly to improvements on the actuating - mechanism described in Specification No. 14,768, A.D. 1901. In the form shown in Figs. 3 and 4, the actuating-cord (not shown) is wound in a central slot d' formed in a worm-wheel d mounted on an axle c carried in flattened ears b<2> formed either on the handle - bar or on a sleeve b inserted in the handle-bar and prevented from rotating by a lug b<1> or by the ears b<2> engaging in slots formed in the handle-bar. The worm g is secured in position on the handlever by a neck g<3> engaging in a slot formed in the hand-lever e, which is formed with ears e<2> mounted on the axle c, and is carried under the handle-bar. The cord passes from the wheel d through a hole h<2> having large ends and formed in a disc h secured to the sleeve b by lugs upon the sleeve b being clinched over slots formed in the disc h. In a modification, the axle c is mounted in the ears e<2> of the lever e, which is pivoted below the worm g in depending ears formed on the sleeve b. When two brakes are used, each handle is fitted with a lever &c., the cords passing from the discs h along the handle-bars to curved guides b, which conduct them to tubes c, d', Figs. 11 and 12. The guides bare tubular for a portion of their length, and are secured by passing them through holes b<2> in the handle-bars until their ends engage smaller holes b<1>, and then connecting them to the handlebars by screws passing through a washer h, Figs. 11 and 12, and through flanges formed on the tubes c, d'. The front-brake cord e is connected to the usual brake-rod f, which is retracted by a spring g surrounding the tube c and compressed between tile handle-bar and a flange f<2> formed on the rod f. The rear-brake cord i, after passing through the tube d' and a telescopic tube d<2>, is secured to a rod k, the two parts of which are detachably secured together by hooked portions k' formed on them and secured in engagement by a screwed sleeve k<2>, as shown in Fig. 11. The rod k is connected to a cord i<2>, which is conducted along the underside of the bottom tube by a guide-tube l, the lower end of which enters a curved tube l<1> secured under the bottom bracket as shown in Fig. 17. The cord i<3>, after leaving the tube l<1>, terminates in a rod n secured by a clip p to a rim brake r, which is retracted by a spring m surrounding the rod n and compressed between the end of the tube l<1> and a flange n' formed on the rod n. In a modification, the tubes d<1>, d' are replaced by a single tube, and the rod k is coupled to the cord i<2> by screwing a sleeve k<2>, Figs. 21, which fits over and engages a flange on the rod k, on to a sleeve k<2>, Fig. 22, which is secured on the cord i<2> by an enlarged head formed thereon by applying solder to the ends of the cord after the sleeve is placed in position. The cord e may be connected, as shown in Fig. 23, to the end of a lever t, pivoted to the forks, carrying a brake shoe to engage the tyre, and retracted by a spring t<2> which engages the fork crown.
