Реферат: 30,376. Crawley, A. Dec. 23. Ball bearings for bicycles and like vehicles. Fig. 1 shows the application to a cone-adjusting wheel hub in which the cones b, b<1> are mounted on right and left hand screw threads c, c<1> on the axle a, and are extended outwards to pass through the forks q, suitable flats being formed on them to prevent rotation. Nuts e, e' lock them in position. The axle a is formed with a head a', and is normally prevented from rotating by a nut a'. The bearing is adjusted by releasing the nuts a<2>, e, e', and turning the axle a. The cupsf, f<1> are screwed into the hub, and are secured by lock nuts h, h<1> respectively which engage threads of opposite lead in the hub or chain-wheel. In the cup-adjusting hub shown in Fig. 2, the cups f<2>, f<3> are screwed into the hub g, the cup f<2> being secured by a nut h<1> as in Fig. 1, and the cup f<3> being secured by a nut p screwing into threads of opposite lead formed in the hub, and by a lock-nut n screwing on to a threaded extension m of the cup. In the crank-axle bearing shown in Fig. 3, the cones u and u<1> are mounted on right and left hand threads on the axle s and have extensions v and v<1> which screw into holes in the crank bosses as shown. Nuts x and x<1> bearing against the cranks lock the cones in position. Flats 3 are formed on the extensions to permit adjustment of the bearings. One of the cones may be formed on the axle, the other cone being secured as shown.
