" .ippiioain fiied .li'prii 2s, 1903. Serin No. 154,681. (No moda.)

To all whom t may concern,.- l Y Be it known that I, WILBERT TULLER GAS- TON, a citizen of theV United States, residing at Hackberry, in the county of Woodward and Territory ofOklahoina, have invented a new and useful Vehicle-Axledof which the follow-A ing is a specification. v The invention relates to improvements in vehicle-axles. f

The object of the present invention is to im'- prove the construction of vehicle-axles and to provide a simple and comparatively inexpensive one adapted when'its bearing-surface has become worn to enablethe same to be renewed with little expense and great convenience.

A further object of the invention is to pro? l tion of a vehiclefwheel to unscrew it accidentally.

With these and other objects in view the invention consists vin the construction and novel combination and karrangement of parts hereinafter fully described, illustrated in the accompanying drawings,wand pointed out inv the claims hereto( appended, it being understood that various changes in the form, proportion, size, and minor details of construction within lthe scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the in venv tion.

In the drawings, Figure l is a side elevation of a portion of a vehicle-axle constructed in accordance with this invention. Fig. 2 is a longitudinal sectional View of the same. Fig. 3 is a detail perspective view of the thimble or skein. Fig. 4 is a 'detail view of the sleeve. Fig 5 is a transverse sectional view on the line 5 5 of Fig. 2.

Like numerals of reference designate corresponding parts in all the gures of the drawings. Y l designates an axle-havinga reduced outer portion 2, provided with inner and outer threaded portions 3 and li,- adapted to engage interior screw-threads 5 and 6 of a thimble or skein 7 Thescrew-threads are of the same diameter and pitchv andA those at each end of the axle will be disposed in adirection oppo siteto that of the rotation of the wheel, so that the wheel when rotating forwardly will not operate to unscrewthe thimble or skein. The thimble or skein forms the bearing of the axle and takes the place of the ordinary spindie, the threaded outer end ofthe reduced portion of the axle being extended beyond the thimble or skein to receive an axle-nut. The Athimble has an exterior configuration similar to that of a spindle and is'provided with a longitudinal groove 7. -The inner portion of the thimble is provided withan annular enlargement 8, adapted to lit into the inner end f ,of an axle-box and provided Ywith an annular groove 9.

. The inner end of the thimble is provided -witha squared portion 10, and it has an annular flange 1l at the inner end thereof. The squared portion l0 of the inner end of the thimble is of the same diameter as the body .portion of the axle, and when the parts are assembled the faces of the squaredportion are arranged flush with `the adjacent faces of the body portion of the axle. The shoulder l,forined by yreducing the axle is preferably beveled, as shown at l2, and the adjacent end of the thimble is flared to fit the shoulder l2.

After the thimble is screwed on the reduced portion of the axle, with its exterior faces at its inner end flush with those of the body portion of the axle, a sleeve 13, which has been .previously placed on the body portion of the axle,is moved outward against the annular flange 1l to embrace or surround the squared portion l() and the adjacent portion of the body of the axle, whereby the lthimble is interlocked with the body portion of `the axleand is held against rotation. The sleeve 13,

which is provided with a square opening to conform to the configuration of the axle and the squared portion ofl the thimble, has a round exterior and is adapted to receive a collar 14 for engaging the flange 11. The flange 11 is provided with exterior screw-threads 15, and the collar 14, which is provided with interior screw-threads to engage those of' the collar, has a shoulder 16 for engaging the flange 11. The sleeve 13 is provided between its ends with an annular shoulder 17, and the collar is provided with an approximately centrally arranged shoulder 18 for engaging that of the sleeve, whereby the latterfis held firmly against the fiange 11. The screw-threads of the flange 11 and the collar 14 are the reverse of those of the axle in order to prevent the forward rotation of the adjacent wheel from affecting the collar. The collar is provided with an exterior polygonal wrench-receiving portion 19, and the squared portion 10 of' the thimble is also adapted to receive a wrench for enabling the thimble to be readily removed when desired. The flange 11 and the collar 14 form a shoulder to receive the inner end of' the axle-box, which is closed by the flange and the collar to form a dust-tight joint.

When the thimble becomes worn, it may be readily removed and a new thimble may be applied to the axle at a very small cost, and the present device obviates the necessity and inconvenience of welding a new spindle to the body portion of the axle. Also the sleeve and the collar reinforce the' axle and the skein and provide a construction substantially as strong as a solid spindle. The sleeve 13 is provided with an extension 20, arranged at the bottom of' the axle and projecting inward on the same a sufficient distance to be engaged by the adjacent axle-clip 21. The bottom extension is provided with a depending projection 22, forming ashoulder for engaging the clip-plate 23 ofl the axle-clip, whereby the sleeve is interlocked with the latter. The extension 2O is interposed between the clipplate and the lower face of the axle and is firmly clamped against the latter by the nose of the axle-clip. The shoulder formed by the projection is located at and engages the inner edge of the clip-plate.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A device of' the class described comprising an axle having threads, a thimble threaded to receive the axle, a sleeve detachably interlocked with the thimble at one end and with the axle at the other end, whereby the former is held against rotation on the latter, and means for detachably connecting the thimble and the sleeve, substantially as described.

2. A device ot' the class described comprising an axle provided with screw-threads, an interiorly-tlneaded thimble arranged on the axle, said axle and thimble being provided with contiguous polygonal portions, and a sleeve conforming to the configuration of' the polygonal portions of the spindle and the axle and holding the former against rotation on the latter, substantially as described.

3. A device of the class described comprising an axle having screw-threads, a thimble interiorly threaded to receive the axle and provided with exterior screw-threads, a sleeve interlocked with the axle and the thimble to hold the latter against rotation on the former, and a collar engaging the sleeve and the screwthreads of the thimble, substantially as described.

4. A device of the class described comprising an axle provided with screw-threads and having a polygonal portion, a skein having a corresponding polygonal portion and provided with interior and exterior screw-threads and engaging those of the axle, a sleeve having a polygonal opening to receive the polygonal portions of the axle and the skein, said sleeve having an annular exterior, and a collar provided with an annular opening to receive the sleeve and interiorly threaded to engage the exterior threads of the thimble, substantially as described.

6. A device of the class described comprising an axle having inner and outer screwthreads, a thimble having inner and outer threads to engage those of the axle and terminating short of the end thereof, said thimble being provided at its inner end with a polygonal portion and having an exteriorlythreaded flange, a sleeve engaging the axle and the polygonal portion of the thimble, and a collar arranged on and engaging the sleeve and interiorly threaded to receive the flange of the thimble, substantially as described.
