to match the screw-threads @L oli' said enlarge Be it known that l, SAMUEL H. RonnsoN, a ment, upon which it is adjustable, to adinitof citizen oi' the United States, residing at Henderson, in the county of Chester and State of rlennessee, have invented certain new and useful lmprovements in Vehicle-Axles, ot' which the following is a specilication.

This invention relates to axles designed chiefly for coperation with vehicle-wheels, the purpose being to provide novel means for taking up wear between the spindle and hub and yet admit of tightening the axle-nut by means of `a wrench or spanner in the accustomed manner, cone-bearings being provided for the wheel and dust-excluding means employed to prevent grinding of the bearings.

Eer a full description oi. lthe invention and the merits thereorl and also to acquire a knowledge ofthe details ol' construction of the means for effecting the resultreference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section of a hub, axle-skein, and adjunctive parts, showing the axle-arm or spindle in full embodying' the invention. Fig. 2 is a detail perspective view ot' the axle-arm and coperating parts separated and arranged in a group.

Corresponding and like parts are indicated by the same reference characters in both views oll the drawings.

'lhe axle is indicated at 1, and its arm or spindle at 2. An enlargement 3 is formed with the axle at a point between it and the spindle 2 and is threaded, as shown at 4, and provided with a cone, as shown at 5. The outer end of the axle-arm or spindle is reduced and threaded, as indicated at 6, and is adapted to receive the axle-nut 7, a series of washers 8, and a jam-nut 9, said parts 8 and 9 constituting, in effect, sections of the spindle or axle-arm to admit or' its lengthening or shortening to effect proper spacing' ot' the cones 5 and l0, the latter being at the inner end of the axle-nut 7. The washers 8 are of different thicknesses to provide for proper spacing ol. the cones 5 and 10 to adapt them to the distances apart of the flaring recesses 11 and 12 at opposite ends of the axle-box 13 or hub, as the case may be. A sleeve 14 is provided. for the enlargement 3 and is internally threaded a snug joint being maintained between the hub and axle, so as to exclude dust and foreign matter lirom the inner cone-bearing. '.lhe sleeve 14 is secured in the adjusted position by any suitable means, and, as shown, a setscrew 15 is provided and threaded into an opening' formed in a side of the sleeve, the inner end ot' said set-screw being adapted to bind upon the threads 4.

The axle-box 13 or eye of the hub `is enlarged at opposite ends, as shown at 1l and 12, t0 receive the cone-bearings 5 and 10, the intermediate portion being spaced from the axle-arm or spindle. The axle-nut 7 is provided at its inner end with the cone 10 and intermediate or' its ends with an outer llange 16, which is channeled upon its inner face to receive a washer 17. The axle-nut is adapted to screw upon the threaded extension 6 oi the axle-arm and is limited in its inner movement by coming in contact with the jam-nut or section 9. This occurs when the cones 5 and 10 are spaced apart a distance corresponding vapproximately to the distance between the recesses l1 and 12, the adjustment being such as t0 prevent binding of the bearings and yet admit oi the wheel turning freely without any lost motion orplay. The adjustment is determined by test, and should the wheel have too much play upon the spindle after the axlenut has been screwed home it is necessary to either substitute a thinner washer :for one of the parts or sections or to remove a washer. On the other hand, should the bearings bind either before or after the axle-nut is screwed home it is necessary either to add a washer 8 or to replace one ot` said washers by a thicker section. This interchange of washers or sec tions results practically in lengthening or shortening' the axle-arm or spindle, as will be readily comprehended.

ln the preferable construction the cone 5 is an integral part of the axle and spindle. A washer 18 corresponding to the washer 17 is inserted in an enlargement at one end of the sleeve 14 adjacent to the hub, so as to insure the formation of a tight joint, which is essential for the exclusion oi' dust from the bearings.

Having thus described the invention, what is claimed as new is* 1n combination, an axle provided with a spindle having' a threaded extension at its outer end and an integral enlargement at a point between the spindle and axle, said enlargement having a portion threaded and its outer end tapered to form a cone, a sleeve mounted upon the threaded portion of said enlargement, means for securing said sleeve in an adjusted position, a series of washers varying in thickness slipped upon said threaded extension, a jam-nut for ooniining said washers, said jam-nut and washers forming Van adjustable extension of the axle-arm to admit of its lengthening or shortening, a hub slipped upon the axle-arm and having its Y opening outwardly fiared at opposite ends, the

inner end of the hub being received by the p sleeve above mentioned, an axle-nut mounted
