BlCYCLE-HUB.

SPECIFICATION forming part of Letters Patent No. 582,861, dated May 18, 1897.

Application filed September 10, 1896. Serial No. 605394. (No model.)

To all whmn it may cncern:

Be it known that we, LLEWELLYN HENRY, residing at Cincinnati, and JAMES O. TEBOW, residing at Elizabethtown; counly of Hamilton, State of Ohio, have invented certain new and useful Im provements in Bicycle-Hubs, of which the following is a specification.

The object of our invention is to so construct the hub and ball-bearings of a bicyclewheel that the ball-'bearings can be ad justed without disturbin g the ball-bearing supports and secured in any desired ad justment by clamp-nuts.

Another object of ourinvention is to so construct the hub that the wheel can be removed from the axle and framc forks without disturbin g the ball-bearings.

The features of our invention are more fully set forth in the description of the accompanyingdrawings, making apart of this specification, in which- Figure 1 is a longitudinal vertical section of our improvement, showing the frame and clamp mechanism in elevation. Fig. 2 is a sectional end View on line 7; o, Fig. 1, with the packing-ring removed. Fig. 3 is a perspective view of the innerface of the packingring. Fig. 4 is a reverse face View of Fig. 3.

A represents the shell of the hub; B, the spoke-disks. A

C represents an outward end extension of the shell A. There is also a slight inward eX- tension of the shell A at a point about opposite the spoke-disks, which forms with the eX- tension C a socket for the reception of cups D, which may be simply seated therein or screw-thread ed, as desired. The concave inner surfaces of said cups form the outer ballbearing support. E represents a sleeve which passes transversely through the shell and forms a housing for the axle. The outer ends of said sleeve are screw-threaded.

F represents cones which are screw-threaded upon the ends of the sleeve E. Theinner faces of said cones are concave and form the inner ball-bearingsupport. I-I represents setnuts tapped on the outer ends of said sleeve to hold the parts to any desired ad justnent.

h represents washers interposed between the nuts H and the cones F. The said sleeve E projects through the set-n ut H a sufficient distance to form a shoulder, against which the fran1e-forks are clam ped by means of nuts In order to prevent dust from working in between the parts, we provide packingrings K, which are recessed on their inner faces and have screw-threads on their outer snrfaces engaging with screw-threads on the inner faces of the end extensions C. Apacking a of suitable material is inserted within the recess. Said rings are preferably provided with orifices d to adapt them to be operated by a spanner-wrench. Cones F are preferably provided with similar orifices.

L represents the axle.

Mode of operation: The cups D are first inserted in the sockets of extensions C, and then the sleeve E is inserted in the shell A, with one of the cones F in position. The balls on this end are then dropped in between the parts D and F. The cone F is then secured to the other end of the sleeve and the balls inserted, the cones turned to the desired adjustment, and the nuts H and Washers h are turned to secure the parts in their adjustment, and packing-rings K are attached. The axle is then inserted through the frame-forks and through the sleeve E, and the forks clamped against the ends of the sleeve bythe outside clamping-nuts I I', and the clamp-nuts I I' clamp the forks against the shoulders formed by the ends of the sleeve. seen that the hearing can be readjusted by Operating the cone F at one end of the' sleeve only, which is a material saving in labor, and

the parts can be taken apart and put together in a simple and convenient manner. The packing-rings protect the bearings and hold the oil therein in a superior manner. The method of clampin the frame and aXle to the sleeve is also a great advantage, allowing the wheel to be detached from the aXle and frame without disturbing the bearings.

Havin g described ourinventiomwe claim- In a hearing for bicycle-wheels, the combination of a hub-shell A, having outward and inward end extensions forming sockets, cups D seated within said sockets, asleeveE screwthreaded at each end, cones on the screwthreaded portions of said sleeve, balls in- It will readily be l IOO In Lestinony WhGl'OOf We have he'eunto set 0111' hands.
