Granted: 1902-05-15
Abstract: 11,849. Rudge-Whitworth, Ltd., and Pugh, J. V. June 10. Driving-mechanism; clutches.-Relates to variablespeed gearing for cycles &c. The shafts a, b to be coupled are formed with discs a<2>, b<2> on their ends ; the disc b<2> is formed with a series of recesses having inclined bottoms for friction balls f, which jam and transmit motion in one direction. When the shafts are in line, both rotate at the same speed ; when out of line but parallel, the speed ratio is varied according to the eccentricity. Fig. 5 shows the application of the invention to the driving-wheel of a bicycle ; the balls are placed in recesses in the chain ring b<2> which works between a pair of discs a<1>, a<2> formed with radial recesses ; the disc a<1> is secured to the wheel hub k and its boss is toothed to engage with the boss of the disc a<2> ; the discs are held together by a screw thimble l. The chain ring is displaced to vary the speed by the pressure of a pair of grooved rollers upon its edges ; the rollers are mounted in a pivoted arm controlled by a wire. In a modified arrangement, the disc a' is fixed to the hub as before, but the disc a<2> is fixed to a sleeve carrying, at the other end of the hub, the chain-wheel, and the disc b<2> is enclosed in a movable yoke ring. Fig. 24 shows a multiple arrangement for coupling two shafts, the axes of which cannot be displaced ; each shaft carries a set of discs, between which work corresponding rings x<4> fitted with bails and mounted in a cylinder which runs on roller bearings in a movable casing. In the arrangement shown in Fig. 26, the discs on the ends of the shafts are replaced by cups which work between a ball 1 and a spherical shell 2 fixed together and movable angularly by means of a ring v mounted on trunnions. This construction allows the shafts to be set at an angle. Instead of balls, pawls and radial ratchet teeth may be used.
