v /y To all whom tt may concern:

\ Be it knownthat I, J AMES A. WHrr'roN,

acit-izen of the Unitedv States, residing at.

Los Angeles, county of Los Angeles, State of California, have invented new and useful Improvements in Axles, of which the following 1s a speclfieation.

4This invention relates to axles and particularlyv to the axles of vehicles such as motor cars or'automo-biles. The object of the invention is to provide improved means fgr securing th'ev wheels to therearaxle which will give a very rigid connection between the parts and which will insurea proper centering pf the wheel on -the hub.

A further object of the invention is to construct the part' so as to enable the wheel to ,bel readily-removed and replaced.

' 1n the drawing forming a part of the annexed specification, Figure 1 is a longitudinal vertical section taken through the Wheel hub at the end of the axle and illustrating the manner of attaching the parts. Fig. 2 is a vertical section taken on the line 2--2 of Fig- 1. Fig. 3 is a perspective showing the Wedge which forms a part of the invention. Fig. 4 is a view similar to Fig. 1 but showing a modified construction of the device. Fig. 5 is' a View similar to Fig. 4:

. yand showing the preferred form of the-invention. v

Referring more particularly tothe parts,

5 represents the rear axle of a car to which' my inventionhas been applied. In applyaxle so'as to give it an angular form presentlng four flat faces 6 and givlng the axle .a substantially square cross section at this point as illustrated in Fig. 2. These faces 6 converge toward each other in the direction of the end of the axle so that the end -of the axle presents the form of a four sided 4hold the wedge securely in space is formed between the hub and the square neck 11.

IV provide a Wedge 12, the construction of which is clearly illustrated in Fig. 3. This wedge has a round head 13, with a square opening 1 3, from the inner face of which four wedged shaped blades 14: extend in- Wardly. so that they are of reduced thickness toward their forward edges and they are adapted tofit in the wedged shaped spaces between the neck lland the square opening l0in the hub. When the wheel is placed on the axley this wedge is forced into position so as to jam the hub tightly on ythe axle and I then place a follower nut 155 on the tubular stud These blades taper in thickness` 7,. This nut is screwed up tight so as to seat against the outeiiace'of the wedge 13 and osition.

The outer edge of the we ge 13 is formed with screw threads 16 and these screw threads enable a cap nut or cap 17 to beattached as in Fig. 1,said nut having a threaded chamber 18 at its inner end whlch receives the thread 16 as shown, the inner face of the cap seating against the end of the hub as indicated. The interior of the cap 17 is -formed into .a chamber 19 which receivesi the nut 15 as shown, and the' outer portion of the cap 17 is formed into a hexagonal head 2O to enable the cap to be applied or removed as will be readily understood. The inner end of the hub 8 seats against a collar 8 formed on the axle.

With a construction such as that described I if it should be necessary on the'road to remove the wheel from the axle this can be readily accomplished simply by applying a wrench to the hexagonal head 2O and removing thc cap 17. The nut is then removed by means of a wrench, and the cap 17 is then replaced and by screwing it up it will withdraw the wedge. This is a very :ulvantagcous arrangement as in some cases the.\\'edgc might be jammed So tightly as to prevent its being readily withdrawn. In order to indicate that the follower nut 15 should first be removed itv is indicated in dotted outline in Fig. 1. From inspection of Figs. 2 and 3 it will be seen that the edges of the blades llla're disposed close together so that the blades 1.11 present substantially the form of a box having slots 21 in its 1onjliliidinal ed es.

In Fia. 4 illustrate' a modified form of 1.19

the invention in which I dispense with the cap 16. In this construction the axle 22 is substantially similar to the axle 5 described above and similarly formed into an angular or square neck 23 which receives the wedge 24 which is adapted to be jammed in the square tapered opening 25 in the hub 26, being'held in position by the follower nut 27 screwing onto the threaded stud 28 on the end of the axle. This construction ha' substantially the same advantages as show, in Fig. l except thatit does not provide for the easy removal of the Wedge. It will be seen that by the construction described the hub can be very securely attached to the axle and that when the wedge is seated it will accuw rately center the hub on the axle.

In Fig. 5 I show the preferred form of the invention. In this form of the invention I provide the threaded collar 2S) of the wedge 32 with a special nut 31 for withdrawing the wedge 32. The follower nut is mounted on a stud 34 as described and jams the cotter 32 on the square neck of the axle. The hub 35 is threaded to receive cap nut 37 as shown.

1. An axle having an angular neck, a. hub fitting on said axle having an angular opening at said neck and coperating with said neck to form a tapering opening, a wedge fitting in said 'opening engaging the sides of said neck, and means for securing said Wedge.

asaltos 2. In combination, an axle having an angular neck, a hub having Van .angular opening opposite said neck, said angular opening and said neck having faces converging in the direction of the middle of said axle, a wedge having a plurality of tapered blades received in said opening around said neck, and means for securing said wedge.

3, In combination, an axle having a tapered neck, a hub having an opening receiving said neck, a tapered wedge adapted to {itbetween the walls of Said opening and said neck so as to jam said hub upon said neck, removable means for securing said wedge and a removable nut engaging said wedge and adapted to withdraw the same.`

4. In combination, an axle having an angular neck, a' hub having an angular opening on said neck, a wedge received over said neck in said opening adapted to jam said hub on said neck, said wedge having a threaded collar thereupon, said axle having a stud, a follower nut on said stud adapted to retain said wedge and a nut engaging the threads'of said collar adapted to seat againstsaid hub.

In witness that I claim the foregoing I have hereunto subscribed my name this 19th day of July, 1910.
