' WHEEL.

Speccatonof Letters-Patent. Batented June 20, 1922..

Application filed october 22, 1920. Serial No. 418,729.

ful Improvement in Vfliheels, ot' whichthe.

:followingv is a specication, reference being had to the accompanying drawing.

invention relates generally tol wheels and it isiespecially `applicable.. to .mine cars and similar. cars in which the axles are secured to the car body while lthe wheels are secured rotatably around the ends of thev` axles.h The. object of this invention isto provide a wheel which will have as little end friction as possibleand in which all the wear will be taken on the removable parts rather than on the wheel casting itself. Another object Ais to provide awheel in which there is an end cap which can be removed when necessary and which will at the same time stay tight and is not clumsy or will not project too far beyond the hub of the wheel. The invention consists inthe construction and arrangement of parts hereinatter more particularly described and. then definitely claimed.

In the accompanying drawings:

Figure l is a vertical central section oi'y a journal having my wheel and bearing applied thereto.

Figure 2 is an end` elevation of the hub of the wheel.

Figure Sis an elevation of a non-rotatable disk.

Referring now to the details of thev drawings by numerals: l designatcs'the axle which may be supported in any desirable way, preferably 'by a pedestal box 2 which. may be of the shape shown in Figure l. The wheel 3 is provided with a hub AI which is open at one 'end and may, if desired.I be provided with an inwardly projecting {lane-e 5 atits inner end, which flange isprovided with an` aperture through which the jou-rnal projects as clearly shown in the drawing. The hub is preferably provided with aninner wearing member 7 whichtaltesthe wear and prevents the wheel itselfv -ffrom being worn. nterposedbetween this `wearing member 7 and the journal or vaxle l are a series-ofjanti-friction 4rollers 8 provided with journals or gudgeon's 9y atfeach end thereof. When ythe `inwardly lprojectiing iiange '5 of the hub is employed, it may,if` desired, beprovided-'withanannul-arf proj ectionvlO which projects from the flange 5j ust about asutar as the journals or gudgeon's l9 project 'fromfth'e rollersl 8'; The outery endk of the hub is `formed'preferably asshown in VFigure 2l and as there shown it is provided with, 4in kthe form/ shown iin' the drawings, three projecting members 12 eaclrof which has a threadedyaperture "14 for the reception `of a screw -as that; shown at 16 in Figure 1. Just to the rear of! one of the `threaded openings 14 is afcoredf hole 18 (see Figure 2) into kwhich is fittedl apin 20,1this pinbei'ng adapted toiit into arecess 2l in a washer 22which is arranged to fit over the free end of 'the journall as illustrated in vFignre'2fthe'purpose of the pin 20 being fto prevent this .washer from rotating. It will be obvious/that other means may be used toprevent such rotation. The washer 22 is provided withopenings 24tlirough whichoilmay pass intothe bear` ing proper. Aroundthe journal 1v and between the heavy washer 22 andthe-ends of the anti-.friction rollers 8 lis a washer 26,A

washer 22 are two additionalv washers 28` and 30, the first of. which may be of com pressed bre if preferred, the washer 28 being'free to move and the washerBOrbeing of the journal is provided with an opening 32 to receive a locking pin 34 and the aforesaid non-rotatable washer 3() has its ends cut so they may be bent to embrace the ends of the pin 34 as shown in Figure 2. The entire outer end of the journal is protected by a cap l0 which is designed to re ceive the end thrust from the axle l and which may be ot any desired construction but preferably of the form shown in the drawings. As illustrated it is provided with an annular flange 36 which is adapted to lit within the three projections l2 formed on the end of the hub shown in Figure 2. The outer surface 0i the 'flange of this cap is formed on an angle as shown at la so that when it is placed in position and the screws 16 screwed home through the openings le, the angular ends of the screws will wedge against the angular portions ist of the flange of the cap 40 and thereby rmly loclr the same against the heavy washer 22 to completely seal the end of the bearing. A wire locking device or a cotter, as 46, may be used to prevent the screws 16 from vibrating loose. The cap 40 is further provided with an oil arrangement as that shown at 50 in Figure 'l which may be of the ordinary kind having a spring valve. This oiling device is so arranged that it can be oiled in any position of the wheel since it comes out radially from the hub with a right angular bend as illustrated in the drawings. In the form shown it is practically out of the way and protected by the projections against blows from objects along the track, and at the same time, if the cap et() should become loose, the oiling device would turn with the cap until it contacts with one of the projecting members 12, when the cap would be prevented from further rotation. TWhen it is desired to remove the wheel from the axle, the pin 34, if opposite one of the holes 111-, may be driven out by a driving tool (not Shown) which may go through one of the holes 14cand drive out the pin 34, the latter passing through the space between .two of the projecting members l2. It', instead of employing three projections l2, as shown, there should be an even number of projections, then the driving tool would pass through the hole lllot one projection and drive the pin 34 through the hole in the opposite projection.

-F rom the foregoing and accompanying drawing, it will be seen that l have provided awheel and bearing for the Same which is provided with a cap as 40, which is se curely held in place where it will be tight and cannot get loose and which will at the same time take a severe end thrust. it the same time a ne reservoir lfor lubricant is formed by the cap 40 as will be noted from an inspection of the drawings. It, for

any reason, the cap 40 should become loose the end pressure will be taken on the end of the pedestal box, a washer 1.8 being pro-A vided at that point to take the wear.

lt will be obvious that changes and modi- Iications may be made without departing from the spirit ot my invention, the scope of which is set 'forth by the appended claims.
