GEORGE HENRY DOWNS, OF NORTH POWDER, OREGON, ASSIGNOR OF ONE-HALF TO WILLIAM E. GRACE, OF PORTLAND, OREGON.

CAR-WHEEL.

Specification of Letters Patent.

Application filed March 24, 1908.

Patented Jan. 25, 1910.

Serial No. 423,002.

To all whom it may concern:

Be it known that I, Gnonen HENRY Downs, a citizen of the United States, and a resident of North Powder, Union county, State of Oregon, have invented a new and useful Improvement in Car-Wheels, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

This invention, while relating more particularly to car-wheels, also applies to vehicle-wheels in general.

It has for its object to obtain an efficient ball-bearing wheel comprising, in its broad sense, a ring-like tread, rotating upon the periphery of a circular web, non-rotatably mounted on an axle-end, sides holding the' tread in place, bearing-balls interposed in an effective way between the bearing or opposed faces of the fixing and moving parts, and chambers for lubricant, all arranged as here inafter more fully described and to accomplish the purposes set forth.

I obtain my object by the combination of parts illustrated in the drawings referred to, in which,

Figure 1 is diametric section of my improved car-wheel; Fig. 2 is a side elevation thereof with the near side plates removed so as to disclose the hub-like web of my wheel; Fig. 3 is a partial elevation of one of the annular members of such side plates; Fig. 4 is an inner side view of one of the outer circular members of said side plates which overlaps and closes the central opening of the annular member of said plates; and Figs. 1

5 and 6 are details of construction more fully explained in the body of this specification.

It is in the first instance to be noted that the shouldered-end of the axle (1, corresponding to the usual journal end of a common car-axle, is made square in cross section, because my wheel is so constructed that the hub of the wheel does not rotate, but instead thereof the rim or ring-like tread, on, of the wheel rotates upon the hub. The web-like hub, Z), of my wheel is provided on its rim with a groove in which to receive bearingballs 0. To admit of the insertion of the bearing-balls, 0, the web, 5, is made with an opening, (Z, closed by a piece (1, of which details are shown in Figs. 5 and 6. On either side of the web, and spaced therefrom, are circular side plates 7:, lo, and between such enter circular plates and the web are annular side plates 9, g, the rims of the latter projecting beyond the periphery of the web. The outer faces of the web 6 are respectively made with annular grooves a, concentric with the axis of the wheel, in which to receive bearing-balls f, and the inner faces of the annular side plates 9, g are likewise made with annular grooves, corresponding with the grooves c, in which to receive said bearing-balls f. Said annular side plates g, g are further provided on their outer faces with annular grooves in which to receive bearing'balls h. The outer circular side plates Z1, 7.1 overlap the inner edges of the annular side plates g, g and they are made with corresponding grooves on their inner faces for said bearing-balls h. The annular side plates 9, g are made with sloping portions i and shoulders j, leaving recesses on their outer faces, in which are seated the rims of the circular side plates Z7, 7;. The cut-away central portions Z of the annular side plates g, g are spaced from the axle-end a, while the eye of the web I) is made square, so as to be rigidly mounted on such axle-end a. The circular side plates 7:, 7; are also made with rectangular eyes if, so as to be rigidly mounted on the axle-end a.

Encompassing the rim of the web 6 between the annular side plates 9, g in the ring-like tread we, made with the usual flange m and shoulders n, n, in which to receive the rims of said annular side plates g, g, as shown in the sectional Fig. 1. The ringlike tread m is bolted by bolts 0 between the rims of said annular side plates r], g. It is preferable to introduce some packing strips at p, 7), (I, q, to keep out dust. The extremity of the axle-end a is threaded so as to receive nuts 0', 2 an intermediate washer s, and a cotter-pin t, or like eontrivances, to securely hold the wheel in place. The manner of assembling the parts of my wheel is self evident from the foregoing description, and particularly from the diametric section thereof shown in Fig. 1.

Before putting on the outer one of the circular outer side plates k, is, the cavities provided by the cut-out portions Z is filled with lubricant, which, passing along the crevices a, it, reaches the grooves of the bearing-balls 0, f, h. It is preferable to fill said cavity Z about half full with lubricant,

lltl

and this will provide ample lubrication for a considerable length :of time, though. the car provided with my wheels be "in continuone use.
