Application filed August 26, 1901. Serial No. 78,334. lNo model.)

1'0 alt w/wm it may corwernx:

Be it known that LQnAnLns E. DAVIDSON,3 citizen of the United States, residingat Greenville, in the county of Bond'and State of Illinois, have invented a new and useful I-Iub- Attaching Device, of which the following is a specification.

The inventionrelates to improvements in hub-attachin g devices.

The object of the present invention is to improve the construction of hub-attaching devices and to provide a simple, inexpensive, and efficient device adapted to be readily applied to an ordinary vehicle-axle and capable of enabling the wear to be readilytaken up without trimming the axle. I

The invention consists in the construction and novel combinationand arrangement'of parts hereinafter fully desc ribed,illustrated in the accompanying drawings, and pointed out in the claim hereto appended;

In the drawings, Figure 1 is a longitudinal sectional view of a hub-attaching device constructed in accordance with this invention and shown applied to an axle. Fig. 2 is a detail view of the device, the parts being separated.

Like numerals of reference designate corresponding parts in both figures of the drawings.

1 designates an axle-nut provided with a rectangular outer portion 2, adapted to receive an ordinary wrench to enable the axlenut to be screwed on and ofi the threaded outer end 3 of a spindle 4 of an axle. The axle-nut, which is provided with interior screw-threads to engage the threads of the axle, is adapted to abut against the shoulder at the outer reduced end of the spindle and has an inner cylindrical extension 5 and is provided with an intermediate exterior annular flange or collar 6, forming a shoulder, as clearly shown in the drawings. The cylindrical extension 5 is provided with exterior screw-threads 7 and is adapted to receive an adjustable cylindrical part or sleeve 8, which engages the axle-box of the hub 9 of a wheel and which holds the same against the collar (not shown) of the axle. The sleeve 8, which is provided with interior screwthreads, is adapted to be moved inward and outward on the cylindrical extension of the axle-nut, and its ,inner end abuts against 'aremovable washer 1.0, which is adapted to be detached and replaced by a washer of greater thickness when the sleeve is adjusted to take up the wear of the axle or the hub. The axle-nut at the right-hand side of the vehicle will be provided with right-hand screw-threads in the usual manner, and the nut at the other side of the vehicle will have left-hand screw-threads, and the sleeves will be reversely threaded, the sleeve at the righthand side of the vehicle being provided with left-hand screw-threads. I The sleeve is provided with an annular groove 12-for the reception of a washer 13, which abuts against the axle-box of the hub 9 and which may be constructed of leather or any other suitable material. The washer 13 is adapted to be removed and replaced by anew washer when it becomes worn, and the engaging portion or end of the sleeve is enlarged to form an interior annular flange, which extends inward beyond the interior screw-threads and which receives the outer end of the bearing portion of the spindle. The engaging end of the sleeve is provided with a pair of oppositely-disposed sockets 15, adapted to be engaged by a pair of projections or lugs of a spanner or similar tool for enabling the sleeve to be readily rotated to adjust it on the cylindrical extension of the axlenut. The sockets 15 are arranged in the annular recess or groove 12, which is of a width equal to the thickness of the axle-box of the hub. The screw-threads may be of any desired size or pitch to enable the desired adjustment to be obtained, and when the parts are adjusted and a washer of the proper size interposed between the flange 6 and the sleeve a solid structure is provided.

It will be seen that the device is exceedingly simple and inexpensive in construction, that it is adapted to be readily applied to any ordinary axle as a substitute forthe ordinary axle-nut, thatit is capable, of ready adjustment to take up the wearof theparts, and that when adjusted it presents a solid structure. It will also be'apparent that the parts cannot become accidentally separated by the rotation of a vehicle-wheel.

What I claim is- In a device of the class described, thecombination with an axle having a reduced portion at the outer end of the spindle, provided with screw-threads and forming a shoulder, and a hub having an axle-box, of an axle-nut closed at its outer end and provided with interior screw-threads to engage those of the axle and abutting at its inner end against the shoulder of the said axle and being of greater diameter than the adjacent bearing portion of the spindle, said axle-nut consisting of an outer polygonal wrench-receiving portion, an exteriorly-threaded cylindrical portion and an intermediate flange 6, the interiorlythreaded sleeve arranged on the cylindrical extension of the nut and provided With an enlarged end extending beyond the shoulder of the axle and arranged on the bearing portion of the latter and projecting inward beyond the exterior screw-threads of the ax1enut to form a flange and provided with an annular recess of a width substantially equal to the thickness of the axle-box of the hub, the washer 13 located within the recess beyond the shoulder against which the nut abuts and supported by the bearing portion of the axle and fitting against the outer end of the axle-box, and an intermediate washer interposed between the flange 6 and the sleeve, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

CHARLES E. DAVIDSON.
