WHEEL CONSTRUCTION.

Specification of Letters Patent. Patented Feb, 22, 1921."

Application filed May 29, 1920. Serial No. 385,226.

This invention aims to provide a con-i 'struction wherein the several parts may be associated for a quick application of the wheel to the axle, or'its removal therefrom,

the hub being designed to provide a channel for the reception of lubricant, which may .be introduced into the channel through a bore communicating therewith.

The nature and advantages of the invention will be betterunderstood when the following detailed description is read in connection with the accompanying drawing, the

invention residing in t e construction, combination and arrangement of parts as claimed;

In the drawings forming part of this ap-' plication,

like numerals of reference indicate similar parts in the several views, and whereciated with'a-portion of the car.

Fig. 2 is an end elevation. 1

Fig. 3 is an enlarged fragmentary view of the modified form of the invention.

Fig. 4; is a view similar to Fig. 1 ther modified form of the invention, f

Fig.5 is afragmentary view of a modified form.

Fig.-6'is a sectional view taken on line 6-6 of Fig. 1 looking in the direction of the arrow.

Fig. 7 is a plan view of Fig. 6.

Referring to the drawings in detail, 10 indicates a portion of a car body, the axle being indicated at 11 and the wheel generally at 12. The axle 11 is received by the pedestal box 13, the latter being held in position beneath the car body by the dove-tail member 14: clearly illustrated in Fig. 6. This member extends under the floor of the Figure 1 is a vertical sectional view through theivvheel, showing the same asso of a car transversely thereof, while theipedestal box 13 is designed to. accommodate itselfto the dovetail member 1.4: as illustrated. One endof the pedestal box bears against a collar 15 fixed to the axle, while the oppositeend is formed to provide a substantially cup shaped extremity 16. 17 indicates an axle strap which is received by a slot in the pedestal box as clearly shown in Fig. 1, the terminals of this strap being secured in any suitable manner to the car body 10. V

The wheel 12 includes a hub 18 of a uniformv diameter throughout its length as shown in Fig. 1, the hub receiving a casing 19 which contains the roller bearings -20. The casing 19 is closed at its ends exceptfor openings 21 through. which the axle 11 proects. duced as at 22 to be received within thejcupshaped extremity 16 of the pedestalbox, the.

reduced portion defining a shoulder 23; disposed in confronting relation to the adjacent end of the cup-shaped extremity 16 of said pedestal box. Surrounding the reduced portion 22 ofthe hub is a gasket 24:, thelatter being interposed between the hub and the wall of the cup-shaped extremity l6 ofthe pedestal box. Surrounding the axle 11 and interposed between the hub and said pedestal box, is a steel wearing-or thrust washer 25, the latter cooperating with the gasket 24 to prevent lubricant or the like from flowing from the hub 18 through the space between the hub and the pedestal box as will be readily understood. v -The opposite end of the hub 18 is also reduced and threaded as at 26 to accommodatea hub cap 27,.the latter being formed with a shoulder 28. Theretaining washer 29 is fitted upon the axle to bear against the outer adjacent end of the One end of the hub 18 is slightly rehub, the retaining washer being retained in position through the instrumentality of the shoulder 28, of the hub cap. An additional steel wearing or thrust washer 30 is also fitted upon the axle and held in position against the retaining washer 29 by means of a cotter pin or the like indicated at 31 which is passed through a transverse bore in the axle as shown.

By reason of the construction thus far described, it is manifest that the component parts of the hub s ructure can be readily assembled to facilitate the application of the v and threaded as at 37.

' tion may be had by an opening 54 normally wheel thereto or the removal of the wheel from the axle 11 as the occasion may require. The hub 18 is provided with an internal annular roove 32 for the reception of lubricant, tfie .channel communicating with a bore 33 closed by a removable plug 34, so that lubricant can be introduced into the channel through said bore. The channel 32 in turn communicates with the interior of the casing 19 through an opening 35, so that the lubricant from the channel can be fed to the roller bearing at 20.

In Fig. 3 I have shown a modified form of the invention wherein the hub is indicated at 36 andhas its outer endreduced The hub accommodates the casing38 which contains the roller bearings 39, this form of the invention differing from the preferred form by providing the cap 40 and a central opening 41 through which the axle 42 projects. In both forms of the invention thus "far described, the caps are held in position on their respective hubs by means of threaded locking elements 43. Surrounding the axle 42 and arranged exteriorly of the cap 40 is a washer 44 which is held in position by means of a cotter pin or the like 45. Otherwise-this form of the invention is the same as that described in connection with Figs. 1 and 2.

In Fig. 4 I have disclosed a modified form of the invention wherein 46 indicates the pedestal box which is constructed the same and associated with the car body the same as described in connection with Fig. 1. The hub 47 of the wheel is reduced at one end and receives within the cup shaped extremity 48 of said pedestal box, washers 49, 50 respectively being interposed between said parts to provide a fluid-tight connection therebetween. In this form of the invention the hub 47 is formed to provide bushings 51 which project inwardly toward each other from the opposite ends of the hub 47, the bushings receiving the axle 52. r The bushings 51 are spaced from the interior of the hub, its intervening space defining a lubricant chamber 53 through which communicaclosed by a removable plug 55. The bushings 51 have their adjacent ends spaced apart, so that the "parts may be properly lubricated by the lubricant contained in the chamber .53. Otherwlse, the invention is cap closes the end of the hub andcompletely conceals from view the end of the axle, and the means for holding the hub positioned thereon. Otherwise the invention is the same as hereinabove described. I

While it is believed from the foregoing description the nature and advantages of the invention will be readily apparent, I

desire to have it understood that I do not.

limit myselfto what is herein shown and. described, and that such changes may bere-. sorted to when desired as fall within the scope of what is claimed. 7 What I claim is: x i" 1. The combination with an axle, of a member arranged above the axleand of dove-tail formation, a pedestal boxfitted upon the axle and having a dove-tailqportion fitted within saidmember, one end ofthe said box being of .cup shaped formation, a wheel including ahub fitted within the cup shaped extremity of said box, gaskets interposed between said parts, said hub being formed to provide a lubricantchamber, and having a bore communicating with said chamber. 7

2. The combination with an axle, of a member arranged above the axle and of dove-tail formation, a pedestal box fitted upon the axle and having a dove-tail portion received by said member, said box being provided with'an annular groove concentric to the axle, a strap having its ends thick and its intermediate portion received within said groove, one end of thebox beingrof cup shaped formation, a wheel including a J hub havlng a reduced portion fitted within the cup shaped extremity of said box, gas '1- kets interposed between said parts, said hub being formed to provide a lubricant 'cham--:
