"-fu "Improvement-sin" Vheels, of which the following is a'specificationl I Our invention"relates' ltb wheels which ro-' tate ontheend'foffaslia'f or'a'xle' I The object thereoij-iis to "provide a wheel which can .be readily removed from its shaft or axle;.which may be locked'in place or uneasiLv-accessiblethan the usual locking-and unlocking devices for wheels of the class to which our improved Jvheel belongs! which may have roller bearings or roller-bearing cages readily. removed and inserted; which contains improved forms of roller bearings: and which is constructed tobe readily oiled.-

Other obgects will appear hereinafter.

Referring to the accompanying drawings,

Figure l is a side elevation of a wheel and a portion of a car with our invention applied thereto; Fig. 2, a longitudinal section through the center of theliub,'theaxle being in elevation; Fig. 3, a detail section showing the locking device and support for the hublockin key; Fig. 4, an edge view of the key, withthe center broken away; Fig. 5, a

detail of one end of an axle with the roller bearing cage in section; Fig. 6. a cross-section of Fig. i; Fig. 7, a detail of an axle with a second form of roller or ,*e in section; Fig. 8, a cross-section of Fig. 6; Fig.

9, a detail of one end of an axle with a third form of rollercage in section; and Fig. 10, a cross-section ofFig. 7.

-.On the drawings, 1 designates theaxle'of a car, the axle being supported in the fixed bearing 2, from which the axle projects so as to form a bearing for the wheel 3 rotatable thereon. The bearing 2 has its outer end made in the' form of a cup-shaped cavitv so as to receive the inner end of the hilb 4 of the wheel 3, the. inner. end 'ofthe .hub engaging the ring 4 which rests against the end, orbottom, wall 5 of the-oup-shaped cavity. The inner end .-of. the hub. is

provided with an annular flange 6 which presents an annular shoulder 7 facing the CORPORATION or" PENNSYLVANIA; i e.

iI-i) provided with vertical holes orinotc-he's 10. j

.A. locking pin 12 is passed down through holes in the top and bottom of the bracket and through one of the notches 10 in the key to prevent endwise movement of the key when itis in its normal, or hub-locking position. lVe have shown eachs'ide of the key pro Med with notches 10, so that the key may be reversed end for end, or side for side when the flange 6 wears it considerably. Dvplaeing the braeket9 and the locking pin beyond the periphery of the wheel, the key mav be locked or unlocked, andwithdrawn from-its locking position in front of z? the flange 6 and returned to its locking position without reaching under the car or its axle or through the spokes of the wheel or between the wheel and the car body. A

car wheels are usually very greasy and dirty, 1-

cars provided with our improvement may have their wheels changed without any necessity for soiling hands or clothes in ma.- nipulating the wheel-lockin devices.

T he interior of the hub isliollow and pro vided with the bearing sleeve or bushing 13. A' cage; provided'with end rings 14:, bearing bars connecting the end rings, and the rollers l5 located between the end rings is located between the bushinglS and thepro- 1- jecting end of the axle. In Figs. 5 and 6, the end rings are connected by the bars 16 each having its. opposite sides hollowed so as to fit adjacent rollers'and form bearings therefor. Preferably the bars surround the rollers sulhciently'to retain them in the cage,

the space betweenadjacent edges of the bars being. less than the vdiameter"ofthe roller.

We have shownthe bars 16 riveted to the rings 14. I In Figs. 7 and 8 there is a p'air of separate bearing bars 16 for each roller, the bars'being hollowed like the bars 16, and

their ends secured in holes in the rings. In

Figs'. 9 and 1 0, a purality ofpa'rallel bearmg rods 16 are placed onopposite sides of each roller.- These rods ma'v 'be considered as the bars 16 with longitudinal portions- 5 removed. The front of the hub is clo's ed exeep't for asmall axial-opening 117 for the spout of an oil ban. The opening 17 is nor-l nlally closed byithe's'pring pressed closure; 18" which 'inay-be pushed'inwardly by the.

' 15.-. The periphery ofthe 'fla ngewfi rotates in "Benga "ement' with the annular packing 21 within the, outer flange of the bearing 2.

Twill-be seen that our'wheels can be .g the roller bearings with grease or U other purposes a minimum of time and witho lt soilingof the olothes or hands uickly removed forthe purpose of in the manipulation of-the barS and the' pin 12.

Ye claini The combination of a bearing, an axle projecting therefrom, a wheel-hub rotatable on the axle; having its inner end adjacent to the said bearing, andfprovided with an annular flange, a slidable locking key normally lying across the path of movement of the flange toward the outer end of the axle, and means beyond the periphery of the wheel for locking the key in its normal p0- SltlOn.-
