BALL-BEARING.

SPECIFICATION forming part Of Letters latent NO. 725,246, dated April 14, 1903.

Applicatio'n filed July 14, 1902.

To all whom it may concern:

Beit known that I, ALBERT ENNIS HENDER- SON, a subject of the King of Great Britain, residing at Toronto, in the county of York,

Province of Ontario, and Dominion of (Janada, have invented certain new and useful Improvements in Ball-Bearings, of which the following is a specification.

This invention relates to improvements in lo ball-bearings; and it has for its object the vices mounted loosely between the cups and supported in the proper position by the balls or by providing means upon the antifriction thrust-bearings for holding the balls separated.

In the accompanying drawings, Figure 1 represents a cycle-wheel axle and hub, partly in section, with my improved ball-bearing in section and in operative position therein. Fig. 2 is a sectional view of the bearing on 0 linens 0t of Fig. 1, with a portion of one cup removed, the entire circle being divided into three segments 00, y, and z, in which are shown in detail the bearing-balls and separating device in segment 00, one of. the thrustbearings in y, and a view showing the top of the thrust-bearing plate removed, as in a. Fig. 3 is a detailed view of the ball-separating device. Fig. i is an end view of one of the thrust-bearing rings and balls. Fig. 5 is a sectional view showing a modified form of thrust-bearing and separating means. Fig. 6 is a detailed plan view of one of these means.

Referring to the drawings, the numeral 1 designates the axle, which is provided with the threaded end 2, and 3 is the hub-shell, which is provided with the interior shoulder 4. Fitting within the hub-shell and adapted to loosely surround the axle is the inner cup or bearing-ring 5, whose inner face, near the circumference, abuts against the shoulder 4 of the hub-shell. This cup is provided with the outer peripheral cylindrical flange 6, whose Serial No. 115,513. (No model-l inner face forms one of the bearing surfaces or raceways for the gearing-balls 7. The other ball cup or ring 8 is provided with the internal threaded portion 9, which is adapted to engage the threads of the axle and revolve therewith, its outer circumference being out of contact with the interior of the hub-shell. This cup is provided with the centrallyarranged cylindrical flange or sleeve 10, whose outer surface provides the inner bearing-surface or raceway for the bearing-balls. It will thus be seen from this construction that the bearing is provided with a two-point contact for the balls, and in order that the end thrust may be taken up and the sliding or twirling motion generally caused thereby prevented I form the oppositely-arranged annular recesses or journals 11, in which are arranged the series of balls 12, which are held in place and form the ball-bearing for the thrust rings or plates 13, which are provided with the substantially parallel flanges 14, the inner flange of these rings loosely contacting the inner wall of the channels 11. It will thus be seen that should the bearing-balls at any time contact either one of the rings 13, instead of the balls having to slide upon a stationary surface these rings, by reason of the balls, will revolve in unison with the axes of rotation of the respective bearingballs proper.- In order that these bearingballs be properly separated, and thereby reduce the friction between same, I provide the two open rings or frames 15, which are provided with the upper and lower narrow bands 16, secured together by means of the intermediate straps or strips 17, which are provided with adjacent openings 18 and 19 and a central opening 20. Mounted between the rings 15 and having their mandrels or pintles 21 journaled in the openings 18 and 19, respectively, are the separating- rollers 22 and 23. The roller 22 is of a greater diameter than the roller 23 and is so journaled as to have its lower bearing-surface above the line between the axes of adjacent bearingballs, while the lower roller, which is of a smaller size, is below said line. It will thus be seen that the rollers 22 and 23 keep the bearing-balls properly separated and so contact the bearing-balls as to cause said balls to support the cage and rollers. In order to secure the rings 15 together, and therebyhold the rollers in their proper places, I employ the screws or tie-rods 24, which are mounted in the openings 20 of the rings. It will be seen that by constructing the separating device as herein set forth the bearing-balls do not contact with the cage, but only with the rollers 22 and 23, and thereby sustain the cage.

In Figs. 5 and 6 I have illustrated the separating device which dispenses with the rings and rollers, and in lieu thereof I form concavities 25 in adjacent faces of the rings 13* to such a depth that the concavities guide the bearing-balls, so that they cannot ride upon the plane surfaces between the concavities, thus always holding the bearing-balls between two opposed concavities and keeping the same separated as they revolve upon the raceways.

My method of relieving the sliding or twirlin motion of the axes of the bearing-balls by means of the ballbearing plates or rings mounted upon opposed faces of the cups or bearing-rings is not only applicable to ballbearings which are provided with separating means, but may be used upon any form of ball-bearing, as it is always applicable and will prevent the twirling motion to which balls are commonly subject, and thereby reduce the friction and tendency to break. In order that the bearing ring or cup 8 may be adjusted readily and held at the proper adjustment, I provide the lock-disk 26, which is provided with threads to engage the axle and revolve therewith, a nut 27 being used to hold the parts more securelyin adjusted position.

What I claim as new, and desire to secure by Letters Patent, is-
