WHEEL.

SPECIFICATION forming part of Letters Patent No. 514,360, dated February 6, 1894.

Application filed March 20, 1893. sis-in No. 466,952. on model.)

To all whom it may concern.-

Be it known that we, VVILLIAM GRAYSON and LOUIS J. OREoELrUs, both of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Wheels, of which the following is a full,.clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to an improved wheel for tricycles, velocipedes, wagons, baby-carriages, &c., and the object of our invention is to produce such a wheel with ball bearings, in which the balls are retained in enlargements at each end of the sleeve of a hub, and yet project sufficiently into the spindle cavicy so as to bear upon the spindle to which the wheel is applied, so that when shipped from the factory, no adjustment of parts is required, and the wheel can be put into use by simply slipping it onto the spindle, as with an ordinary wheel, and at the same time to construct such a wheel so that the balls will hear directly upon the spindle at right angles thereto.

Our invention consists in features of novelty hereinafter fully described and pointed out in the claims.

Figure Iis an elevation, illustrative of our invention. Fig. II is a transverse section, taken on line II-II, Fig. III. Fig. III is an axial section, taken on line IIIIII, Fig. I. Fig. IV is an elevation. Fig. V is a detail section, showing one form of a ring for holding or retaining the balls in position. Fig. VI shows a modified form of the ring for holding the halls. Fig.VII is an elevation, illustrating a difierent form of the invention from that presented by Figs. III and IV.. Fig. VIII is a longitudinal section of the form represented in elevation by Fig. VII. Fig. IX represents still a difierent form of the invention. Fig. X is an axial section showing the form of ring illustrated in Fig. VI located within an enlargement of the hub.

Referring to the drawings, 1 represents enlargements of the hub of a staggered wheel, to which the spokes 2 are secured, in any suitable manner. The enlargements 1 are connected by a sleeve 3, which, in the form shown in Fig. III, extends a short distance into the sockets of the enlargements to form innerside supports for anti-friction balls as shown at i.

5 represents the anti-friction balls fitting in the enlargements 1, and retained therein bya suitable encircling bearing ring 6. We

' have shown this ring having a retaining flange 7, of slightly dished shape, providing an inturned inner margin which in connection with the slight extension dot the sleeve 3 holds the balls loosely in place, and keeps them from dropping out before the wheel is placed on the spindle, upon which it is designed to'be used. The ring fits snugly in the enlargement, with sufficient friction to prevent it from dropping out.

In Fig. VI we have shown the ring provided with two slightly dished retaining flanges 8. In this form the balls are inserted in the ring and then the inner edges of the retaining flanges are turned or slightly dished inwardly to retain the balls in place, and the ring containing the balls is then inserted into the enlargement as shown in Fig. X.

In Fig. VIII we have shown the sleeve of the hub cast in one piece with the enlargements, and have shown the ring 9 with a slightly dished flange 10, which in connection with the slightly dished ends 11 of the hub, holds the balls in place.

In Fig. IX we have shown the retaining flange 12 associated with a ring l2 located on the hub within the enlargement. In this form the retaining flange is slightly dished, as shown, and in connection with the slightly dished end 13 of the hub holds the balls in place. The halls extend slightly into the spindle cavity of the hub, or slightly beyond the interior face of the hub, so that when the wheel is placed on the spindle, the balls will bear directly thereon at' right angles to the spindle, thus avoiding the use of unnecessary parts and unnecessary friction.

Our wheel is designed to be used on any spindle of the proper size to receive it, and does not difier in this respect from an ordinary wheel without ball bearings.

Having thus described our invention, the following is what we claim as new therein and desire to secure by Letters Patent:

1. A wheel provided with a hub constructed with an enlargement at each end, asleeve connecting the enlargements, spokes secured at their inner ends in said enlargements, antifriction balls projecting into the spindle cavity and bearing rings en circling the balls, each ring having a retaining flange formed with an inturned inner margin for holding the balls in position, substantially as described.

2. The combination of thehub enlargements 1, 1, connecting sleeve 3, spokes 2 secured in said hub enlargements, anti-friction balls 5 protruding within. the spindle cavity of the hub, and rings 6 encircling the balls 5, affording radial bearing thereto and each ring hav- 5 ing two inturned flanges 8, 8, which retain said balls within the hub, as explained.
