To aZZ whom it may concern.-

lle it known that l, LOGAN MOKNIGHD BU L- Li'r'r, a citizen of the United States, residing at St. .llauhin the county of Ramseyfitate of Minnesota, have invented certain new and useful Improvements in GanWhecls, of which I do declare the following to be a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

My present invention has relation to carwhecls designed to rotate freely upon their axles, and partieularl y does it relate to the improvement oi that class oisuch wheels wherein provision is made for the lubrication of the journals without the necessity for the employment of separate journal-boxes.

The object of my invention is to provide a simple, durable, and effective means whereby a thorough li'ibrication of the journals may be secured; and to this end my invention consists in the various novel features of construction, hereinafter described, illustrated in the are companying drawings, and particularly defined in the claims at the end of this specification.

Figure 1 is a view in side elevation of a car-wheel having my improvements applied thereto. Fig. 2 is a view in vertical crosssection on line :r as of Fig. 1. Fig. 3 is a detail view, in side elevation, of the hub of my improved wheel. Fig. l is a view in vertical section through the hub at a point immediately adjacent its central web.

lily present invention is showii as applied to a car-Wheel, the bed y of which is composed of two sets or series of wooden segments, A, the inner ends of which bear against the periphery ol the hub B, and are there held in the annular grooves formed by the flanges I; and the intermediate web, h',while their outer ends are connected with the tireG of the wheel by means of the rctaining-ring D, the ring or fillet 1*], and the through-bolts P, which latter pass through the retaining-ring, the fillet, and the outer ends of the segments, and hold these parts securely to the depending flange c of the tire. It will be understood, however, that while I have shown In y invention as applied to a car-wheel having a wooden body constructcd and connected with the hub and periphery in the manner above defined, and while the invention is particularly suited to this kind of wheel, I. do not wish my invention to be understood restricted to such form of wheels, since it is applicable, also, to carwheels of various other constructions.

The central portion of the hub B of the wheel consists of an annular beariugplate, b, which, together with the end plates, b and Z1, and the periphery of the hub, form a closed annular chamber, G, adapted to receive a quan tity of suitable lubricant. Across this annular chamber G extend the division-plates g, having openings 9 therein communicating with the main portion of the annular chamber G, and through the annular bearing-plate b" of the hub, at a point between the divisionplatcs g, is formed a delivery duct or channel, If, through which the lubricant will pass to the journal of the caraxle. My purpose in thus providing the annular chamber G with the division-plate gis to form a receptacle, G, for cotton waste or like material, through which the oil or other lubricant will gradually filter before passing through the delivery-duct If to the face of the journal. It will be seen that by thus providing a receptacle for .the cotton waste at a point opposite the delivery duet b it will be in thebest position for delivering the lubricant to the journal, and as this receptacle G, wherein the cotton waste is re tained, communicates through the openings in the division-plates with the main body of the chamber G the cotton waste will be saturated with the lubricant so lon there is any within the annular chamber, and while preventing the too free escape thereof will insure its proper delivery to the journal. Through the end wall, 12*, of the hub B there are preferably formed two openings, fitted, respectively, with the screw-threaded caps H and H, one of these openings communicating with the annular chamber G, and serving to admit the lubricant thereinto, while the other opening communicates with the receptacle G for the purpose of permitting the introduction of cotton waste to such receptacle.

From the foregoing description it will be seen that when the receptacle G" has been suit- KOO ably filled with cotton Waste or like material, and the lubricant has been introduced into the annular chamber G, the cotton waste will speedily become saturated with the lubricant, which will gradually pass thence through the delivery-duct 1) onto the wearing-face of the journal. By thus forming the hub B with a chamber for lubricant about its annular bearingplate, and by forming the walls of such chamber integral with the annular bearing and periphery of the hub, I am enabled to produce an effective means of supplying lubricant to the journal, and this, too, without increasing to any considerable extent the cost of the wheel. Moreover, it is apparent that by constructing the walls of the chambers G and G as integral parts of the hub I avoid all danger of the leakage of the lubricant, which would be liable to occur in case the sides of such chamber were formed separate from the hub and attached thereto by bolts.

While I have illustrated in the accompany ing drawings what I regard as the preferred embodiment of my improvements, it will be readily understood that the precise details thereof may be varied without departing from the spirit of the invention.

It will be observed that in the periphery of the hub B are several holes I)", caused by the withdrawal of the pins which serve to sustain the sand core during the operation of casting the hub. These holes may be subsequently plugged up, or may be stopped, as shown in the drawings, by means of small lead caps 8, held in place by the pressure thereon of the inner ends of the Wooden segments.

I am well aware of the construction of lubricating devices illustrated in Letters Patent No. 256,841, granted April 25, 1882, and No. 293,070, granted February 5, 1884, and I wish it distinctly understood that I make no claim to the features of construction of invention set forth in said patents.

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

1. The combination, with a body of a carwheel, of a hub formed separate therefrom, said hub consisting of a perforated annular bearing-plate, I)", an annular chamber, G, for lubricant, the walls whereof are formed integral with said beaiingplate, said chamber surrounding said bearing-plate and being provided with the division-plates 9, extending entirely across said chamber and having openings g therein to form areceptacle, G, for cot ton waste orlike material, said division-plates being located at each side of the perforation through the annular bearing-plate, whereby the cotton waste may be securely retained separate from the lubricatingchamber and abovethe opening of the bearing-plate, substantially as described.

2. The combination, with a body of a carwheel, of a hub formed separate therefrom and having its periphery provided with suitable fianges, and having formed integral with said flanges aperforated annular bearing-plate for the caraxle journal, a closed chamber for lubricant surrounding said bearing-plate and having its walls formed integral therewith, said closed chamber being provided with the division-plates 9, having openings 9, to form a cotton-waste receptacle opposite the perforation of said bearing-plate, substantially as described.
