SPECIFICATION forming' part of Letters Patent No. 634,774, dated October 10, 1899.

Application filed April `29,1li99. 4

To all whom, it may concern/: A 1

Be it known that I, vEUGENE E. STUvEn, a citizen of the United States of America, residing at Blue Mound, inthe county of Macon and State of Illinois, have invented certain new and useful Improvements in Axles .and Bearings, of which the following is a speciiication.

My invention ,relates to an improvement in axles and bearings, and the Objectis to provide a simple, inexpensive, and eective construction for the purposes sought; and it consists in the main of a straight round .wooden axle formed or turned in three successivelydiminishing diameters toward the extreme alsovformed both inside and outside in three diminishing diameters and adapted to receive andfit the end of the axle,roller-bearings itted to and encircling the bearing of the skein, a'wheel-hub inclosing and adapted to turn von the bearings, a removable'nut, and

both its inner and outer ends.

My invention still further consists in certain novel features of construction and co mf binations of parts, which will'be hereinafter more fully described,and particularly pointed ont in the claim. A

In the accompanying drawings, Eigure l isY a longitudinal sectional View of the axle and skein, showing the means for fastening the two together at the inner and outer ends and the rollers in position. In' this iigure the hub is also shown insection, as well as the nut. Fig. 2 is a view showing the hub partly removed, which is the positionof parts when' oil# ing and Fig. 3 is a detached view of the nut.

Arepresents a wooden axle formed or turned on three kdiminishingdiameters marked l, 2, and 3, respectively, with the shoulders 4 and 5 between the portions l and 2 and 2 and 3, respectively. These portions are round or cylindrical, or, in other words, are perfectly straight and without taper.

B is the skein. This skein coforms in its ting the three diminishing diameters of the wooden axle securelyand abutting snugly against ythe shoulders 4 and 5. Although the serial No. 715,043. 'mamans place `by friction, yet, nevertheless, as an additional means for securing it in place one or more bolts 6 6 are passed through the inner end of the skein, Where they are held by nuts 7 7 in the usual manner, after which their ends are upset, or, it is needless to say, although perfectly obvious,that rivets or screws could be substituted for these bolts. A nail or screw 8 is driven or screwed longitudinally.

into the extreme outer end of the skein and axle, and thusfbymeans `of the screws, bolts,

rivets, nails, or what not at the two extreme' ends of the skein the latter is securely held on the axle against the possibility of lateral or longitudinal movement, or, in fact, any move ment whatever of the skein with respect 'to the axle on which it is secured. It might also be said that the tendency of all of these portion of the skein constitutes the bearing upon which the hub turns, and entirely encircling-this bearing portion and interposed between it and the bore ofthe hub are the roller-bearings 9 9, which extend. the entirelength of this bearing portion, abutting at their inner ends at `the inner shoulder 10 of the skein and extending at the other ends flush with the outer shoulder 11 of the skein. The nut 12 screws onto the outer end of the skein and its flange 13 is .of sufficient diameter to incluse the ends of the roller-bearing, the nut having that additional vfunction besides the ordinary ones of a hub-nut.

To oil or grease the hub, it is merely necessary to remove it part way, as indicated in Fig. 2, the hub in that Way retaining the roller-bearings against displacement, as its bore isr perfectly cylindrical, and it therefore iits these bearings when entirely on or partly ICO position temporarily or otherwise. In this way the entire interior of the hub bears equally and uniformly upon the rollers, and the rollersin turn bear equally and uniformly throughout their entire lengths upon the intermediate hearing,` portion of the skein.

The Construction is a thoroughly practical one, as it can readily be seen that the parts are so constructed as to be possessed of snperior strength. At the same time the several parts are simple, and hubs constructed in this way not only have a minimum of frietion, but also they remain lubrieated for a long period and do not Wear out easily or beeomeinoperative with Wear.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described Without departing from the spirit and scope of my invention, and hence I do not Wish to limit myself to the exact construction herein set forth; but,

Having thus described my invention, what I claim as new, and desire to seeuro by Letters Patent, isd y The Combination with a wooden axle having the end formed with a series of diminishing diameters and a skein of corresponding form fitted thereon and Secured at both ends to the axle, the intermediate portion of the skein being` cylindrical in form, of rollerbearings surro unding the cylindrical portion, a hub having a cylindrical bore which surrounds and turns upon the rollers, said rollers and hub abutting,` the enlarged end of the skein and a nut screwed onto the portion of the skein having a smaller diameter, with its flange abutting the outer ends of the cylindrieal portion of the skein and reaching over the outer end of the rollers.
