The sections 1G drawings. of the locking-collar are each semicircular in Referring to the accompanying drawings, form, and each comprises upon its inner sur- 1 designates a 'wheel-hub, in which is fitted face an outer segmental iiange 17, adapted the axle-box 2. The hub l is provided near to enter the groove 13 of the axle, and anroo o its outer end with an inwardly-projecting other segmental flange, 18, adapted to enter annular flange 3, within which fits snugly the between the flange 8 of the axle-box and the f f y25 arranged one on each side of the divided rlhese cups communicate with ther Wheel-hub. When the collar is closed, the

circumferential flanges 8 and 12-are confined between the flanges 1'7 and 18 of the collar,

and the Wheel is thus held securely upon they axle. The collar or its sections 1G are also to the joint and alsofmore effectivelyexcluding foreign matter. rlhe collar-sections are provided at their lower portions with inter- .stud 20.

lapping perforated ears, asshown, which receive the fulcrum bolt or pin 15 above referred to, and said sections are provided at their upperportions with half-studs 20, which when brought together form a cylindrical stu dv yadapted to receive, pivotally, a cap 21.

This cap comprises a hollow hub adapted to fit over thestud 2O and lock the collar-sections together, andl said hub is provided with opposite perforations 22, through which a springpin 23 may beV passed, the said pin alsopassing through notches 24 in the meeting edges of thehalf-studs 20. By removing the springpin 23 and the cap 2l the sectional collar may be detached, after which the wheel may be removed from the spindle. It is not, however, necessary to remove the Wheel in order to lubricate the bearing, as the ylubricating material may be introduced through oil-cups interior of the collar, as shown in Fig. 6, and their upper edges are fiush With the corresponding edge of the stud 20, adapting them to be covered bythe oppositely-projecting longitudinal extensions of the cap 21 When the latter is turned in positionl to be locked by pin 23. At the same time the cap maybe turned, as in Fig. 5, to lubricate the spindle Without unlocking the collar-sections.

The construction above described provides a very efficient and convenient manner of securing wheels upon their spindles and also axle-boxes Within their hubs, and at the same.

axle-box removably fitted in the hub, thesaid ll f ydust cap or plate and axle-box bein g provided,

one with a hub portion having radial shoul- Vders and the otherL with Webs or shoulders which cooperate. with the shoulders on the first part for locking the axle-box in place, substantially as described.

2. A Wheel-,hub having its outer end closed by a dust-cap xedly attached thereto and provided With an inwardly-extendin g hub portion having' radial shoulders, in combination with an axle-box having its outer end formed to receive said radial shoulders and provided itself with Webs or shoulders which cooperate with the shoulders of the dust plate or cap tolock the axle-box in place, substantially as described.

3. The combination Witha Wheel-hub, of an aXle-boxremovably fitted therein and provided at its inner end with a circumferential flan ge, an axle provided with a similar flange, and a locking-collar embracing .said iianges for holding the same together, the said'collar being made in substantially equal halves or sections.ffulcrumedy on the axle and provided at their free ends each with a half-stud, a cap removably fitted over said half -studs and locking the free endsof the sections together, and means for preventing the displacement of said cap,substantially as described.

4. The combination with a Wheel-hubfand the axle-box therein, of a locking-collar embracing shoulders on the hub and axle for locking the same together, said collar being made in substantially equal halves or sections fulcrumed at one end on the axle and provided at or near their free ends with oilcups, and a cap.. removably fitted to said oilcups and adapted to lock the free ends of said sections together, substantially as described.

5. The combination with a Wheel-hub and the axle upon which the same is mounted, of a locking-collar embracing shoulders upon the hub and axle for locking the same together, the said collar being' made in two sections fulcrumed at their lower ends upon the axle and provided at their upper endseach With a half-stud, a cap removably fitted over the stud and adapted to lock the swinging ends of the collar-sections together and also to permit lubricating material to be introduced to the cup, and provision for retaining said cap in place, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
