SPECIFICATION forming part of Letters Patent No. 788,347, dated April 25, 1905.

Application filed June 13,1904. Serial No. 212,374.

To ti/Z whom, it may concern:

Be it known that I, JOHN BEVINGTON, aciti- Zen of the United States, residing at Cordova, in the county of Seward and State of Nebraska, have invented certain new and useful Improvements in Antifriction Bearings; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in axle-skeins.

The object of this invention is to construct an axle skein provided with antifrictional rolls, which are retained in an assembled position by removable means secured in an approximately central position ofjsaid assembled rolls. 1

Another object of the invention is to .provide an axle-skein with antifrictional rolls which are sprung into their normal assembled position and retained in such position by removable means.

A still further object of the invention is to simplify the construction of and minimize the number of parts employed in the construction of an axle-skein.

With these and other objects in view the invention consists in certain other novel con structions, combinations, and arrangements of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularlypointed out in the claims hereto appended.

In the drawings, Figure 1 is an inverted plan view of an axle-skein constructed in accordance with the present invention Fig. 2 is a view inside elevation of a device constructed in accordance with the present invention shown in an inverted position. Fig. 3 is a longitudinal sectional view of an axle-skein constructed similarly to the construction depicted in Figs. 1 and 2, the same being shown in an inverted position. Fig. 4 is a perspective view of a bearing-box employed in the present invention.

In carrying out the present invention 1 provide an axle-skein 1 with a plurality of approximately parallel longitudinal ways or grooves 2, formed upon the solid spindle por- 8. The opposite end of the antifrictional' roll 8 is journaled in a movable box 9. The box 9 comprises in its construction an approximately rectangular body portion 10, which is provided with diametrically opposite recesses 11, in which the projections 12 of the antifriction-rolls 8 are adapted to be positioned. Integral extensions 13 are secured near the base of box 9 and extend longitudinally therefrom. Said extensions18 are concaved for the purpose of forming a bearing 10, which is adapted to be engaged by the end portion of antifrictionrolls 8. Similarlyconstructed bearings 14 are formed in each way 2 near each end thereof adjacent to the recessed portion 7. Journal-boxes 9 are preferably secured in a central position in each of the grooves or ways 2. Said members 9 when assembled with the pair of rolls that are mounted in each way provide a positive locking device for retaining said rolls in an assembled position. It will be obvious that the rolls 8 extend beyond the bearing-surface of the solid spindle portion 3 when mounted in an approximately horizontal position within thei grooves or ways 2, as depicted in Figs. 1 an 3.

The outer end of the spindle is provided with an integral portion having a plurality of recesses 7 contiguous to the ways or grooves 2, and thereby provide a comparatively rigid end portion for said grooves.

When itis desired to mount the removable antifriction-rolls 8 and their removable journal-boxes 9 within each of theways 2, it will be necessary to position the rolls within the ways, so as to cause theouter ends thereof to engage the journals 7, formed upon the spindle. After this has been accomplished the inner ends, which are provided with extensions 12, are positioned similarly to that depicted in Fig. 2, thereby causing said extensions 12 to engage the recesses or journals 11, formed upon box 9, and by exerting inward pressure upon said box the rolls 8, together with the same, will be sprung into the way and retained in a fixed position therein.

After the wheel has been mounted upon the spindle it will be impossible for the rolls and member 9 to become removed from their assembled position within the groove or way 2.

The metal of which the spindle is formed is of sufficient resiliency for the purpose of permitting the springing of the rolls into their normal position, as depicted in Fig. 3, and by actual experience I have found that the rolls will be positively retained in their assembled position, but will be permitted to have free rotary movement. It will be impossible to insert one of the rolls in the way, together with journal-box 9, and subsequently insert another roll, owing to the construction of the coacting members.

It will be obvious from the foregoing description that the antifriction-rolls are adapted to engage a portion of the-hub'of a wheel at all times when assembled therewith, owing to the position of said rolls upon the spindle portion 3 of the axle-skein.

While I have described the detail construction of the spindle and the ways formed therein, together with the rolls and the removable journal-box, it will be obvious to one versed in the art to which this invention relates that certain alterations, modifications, and changes may be made in the construction of axleskeins according to the present invention, and I therefore reserve the right to make such alterations, modifications, and changes as shall fairly fall within the scope and spirit of the present invention.

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

1. A device of the character described, comprising a spindle having a groove, the end walls of the groove being fixed with respect to the spindle, rolls disposed within said groove,

"and a laterally-removable box interposed between said rolls for normally maintaining the same in position, lateral movement of the box permitting removal of said rolls.

2. A device of the character described, comprising a spindle having a longitudinal groove of the same width throughout its depth, the end walls of the groove being lixed with respect to the spindle, rolls positioned within said groove, and a laterally-removable box provided with parallel sides interposed between said rolls for normally retaining the same within said groove, lateral movement of the box permitting removal of the rolls.

3. A device of the character described, comprising a spindle formed with a groove, the end walls of the groove being fixed with respect to the spindle, a plurality of rolls disposed longitudinally within said groove and arranged end to end, and alaterally-removable locking-box interposed between said rolls and engaging the ends thereof for normally maintaining the rolls within the groove.

4:. In a device of the character described, the combination of a spindle, provided with a longitudinal groove having a fixed closure at each end, a recess formed in said spindle at each end of said groove, a concaved, integral portion formed upon said spindle near each end of said groove, rolls provided with integral, annular extensions formed upon each end journaled within said grooved portion of the spindle, a laterally-removable box positioned between said rolls comprising a body portion provided with parallel sides, the ends of said box provided with recesses, and an integral concaved portion projecting in opposite directions near the base of said box.

5. The combination with a spindle, of rolls carried thereby, and laterally-movable locking means interposed between said rolls for normally maintaining the same in position, said locking means being adapted to lie normally in approximately the same horizontal plane with the rolls, and being adapted to be moved laterally for permitting lateral removal of the rolls from the spindle.

6. In a device of the character described, the combination with a spindle formed with a groove, the end walls of the groove being fixed with respect to the spindle, of rolls journaled in said groove, and a laterally-removable box interposed between said rolls and formed with integral bearing extensions near the base thereof, lateral movement of said box being adapted to permit removal of said rolls from the groove.

7 A device of the character described, comprising an axle formed with a plurality of approximately horizontal grooves, the end walls of each of said grooves being fixed with respect to the spindle, rolls disposed within each of said grooves, and locking means interposed between said rolls and susceptible of lateral movement for releasing the rolls.

In testimony whereof I hereunto aflix my signature in presence-of two witnesses.

JOHN BEVINGTON.
