CAR-WHEEL.

SEECIFICATION forming part of Letters Patent No. 326,433, dated September 15, 1885.

(No model.)

To @ZZ whom it may concern:

Be it known that l, ROBERT W. Jnss, of Riverton, in the county of Sangamon, and in the State of Illinois, have invented certain I'mprovements in Lubricating Oar-VVheels; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure l is a perspective view of my wheel. from the outer side. Fig. 2 is a like View of the same with a portion of the hub broken away to show the interior construction. Fig. 3 is a central section upon an axial line, and Fig. 4 is a section upon a line with the plane of rotation. u

Letters of like name and kind refer to like parts in each of the igures. Y

The design of my invention is to give to a ear wheel and axle a maximum of efficiency and durability by insuring a constant and sut`- cient supply of oil to their bearing-surfaces; and to this end said invention consists, principally, in the construction of the oil-recess within the hub of the wheel, substantially as and for the purpose hereinafter specied.

It consists, further, in the special construetion of thewheel and its combination with the axle, substantially as and for the purpose hereinafter shown.

In the carrying into practice of my invention I employ a car-wheel, A, of any usual pattern, and within its hub aform an annular recess, c', that entirely surrounds the central bearing portion,a2. The rear end of said part a unites with and forms part of the inner end of said hub; but at its outer end the former is connected with the adjacent portion of the latter by a number of lugs or braces, a3, which extend radially between said parts. The inner or axle-bearing portion, a2, extends, preferably, to or near the outer face of the wheelA, While the hub proper, a, extends outward an inch or more beyond said Wheel-face and forms a continuation of the recess or chamber c.

The axle B has the usual form of axlearm, b, which is adapted to fit into the axial opening in the wheel A, with the collar b at its inner end contained within a suitable recess, a, at the inner end of the hub a, and its outer end projecting sufficiently beyond the bearing portion a to permit of the insertion therein of a pin or key, G, that operates to lock said axle and wheel in relative positions. For the purpose of enabling said key to be placed in or removed from position, the projecting portion of said hub c is provided with an openby a pivoted cap or other equivalent means. 4

From said chamber oil is permitted to pass to the bearing-surface of the axlearmb by means of a number of openings, ci, that pass radially through the bearing. portion a2 and furnish communication between the interior of the latter and said chamber.

As constructed it will be seen that the bearings of the wheel and axle-arm are surrounded by oil which cannot escape from its chamber, and by the movements of said wheel is caused to circulate freely throughor between the bearing-surfaces. In order to break or arrest the flow of said oil around the outer side of .-its chamber in consequence of centrifugal force, Iprovideatthreeor more points around the inner periphery of said chamber a radially inward projecting anges as, which extend from the rear end of said chamber to a point upon a line with the outer end of the bearing portion c2.

The wheel described is cast in one piece by coring out its oil-chamber, and only requires that its axial opening, the outer end of its bearing portion a2, and the collar-recess a4 be dressed with suitable easilyfoperated tools, and the openings a5 and c formed in order to fit said wheel for use.

Having thus fully set forth the nature and merits of my invention, I claim- 1. The car-wheel A, provided within its hub a with an oil-chamber, a, which surrounds the exterior and outer end of the axle-bearing a2, the radial braces a3, extending between the outer end of said axle-bearing and said hub, the oileopenings ci, formed in said axle-bearing,and
