SIECIFIGAJIIIOLT, forming part of Letters Patent No. 694,472, dated March 4, 1902. Application filed March 28, 1900. Serial No. 101516' (N0 mm To @ZZ whom t may concern/.-
Be it known that I, JOHN'HAERINGTON, a subject of the Queen of Great Britain, residing at Coventry, in the county of Warwick,
England, have invented certain Improvements in Friction-Clutches, of which the following is a specification.
My invention relates to friction-clutches, and has for its object to combine a reliable grip in one direction anda veryfree rotation in the opposite direction. ject by the mechanism illustrated in the accompanying drawings, which show a clutch suitable for use Vin the hub sprocket-ring of a rear-driving safety-bicycle.
Figure I is a side elevation, partly in seca tion. Fig. IIis a transverse section of some of the parts. Fig. IIIl is a side elevation of the cam-collar. Fig. IV is aside elevation of the carrier. Fig. V is an elevation of one of the side plates. Figs. VI to VIII show details.
Like'numerals indicate like parts throughout the drawings.
The cam-collar2 is provided with4 inclined surfaces 3 and radial projections 4 and is fixed Y to or forms part of the hub-body or other part of the machine that is to be driven. Between the inclines 3 and the inner periphery ofthe outer ring 5 I introduce a number of rollers 6, and in the term rollers I include balls, bowls, and the like. The rollers are mounted in a carrier 7, which is provided with radial slots 8 to receive the ends 9 of the rollers, which are preferably turned down for the purpose. The ,carrier consists of two plates 7 7, lying on either side of the cam-collar 2, which are connected by rivets 10, passing clear of the inclines 3. The projections 4 are bored with-holes 11 to receivev pins 12, on which are threaded springs 13. The said springs extend beyond the pins -12 and are compressed between the faces of the projections 4 and the respective rivets 10, so that the carrier is impelled in such a direction relatively to the collar thatthe rollers are always held ready to grip between the inclines 3 and the inner surface of the ring 5. The rollers may be made up of an inner solid spindle coveredby sleeves loose thereon, as indi- 5o cated in dotted lines in Fig. VI.
On rotation of the ring 5 in the direction of the arrow 14 the rollers immediately grip and the cam-collar 2 is carried round with the said ring 5. On the said rotary effort being discon- 5 5 i tinued the rollers release and rotating on their ends form a roller-bearing for the ring 5. The
What I claim as my invention, and desire 7o to secure by'Letters Patent of the United States, is-
1. In a clutch, the combination of an inner part, an outer part, rollers introduced between the said inner and outer parts, inclines for the said rollers, a carrier for the said rollers, and radial slots of limited depth in the said carrier adapted to receive the ends of the said rollers, substantially as and for the purpose set forth. j
2. In a clutch, the combination of an inner part, an outer part, rollers introduced between the said inner and outer parts, inclines for the said rollers, a carrier for the said rollers, and springs introducedv between the said inner part and the said carrier, substantially as and forthe purpose set forth. 3. In a clutch, the combination of an inner part, an outer part, rollers introduced between the said inner and-outer parts, inclines 9o for the said rollers, a sectional carrier for the said rollers and springs introducedbetween the said inner part andthe said carrier, sub- `stantially as and for the purpose lset forth. y
