JAMES H. \VATT, OF BARNESVILLE, OHIO, ASSIGNOR TO THE WATT MINING OAR WHEEL COMPANY, OF SAME'PLAOE.
SELF-OILING CAR-WHEEL.
SPECIFICATION formingpart Of Letters Patent N0. 494,661, dated April 4;, 1893.
Application filed December 24, 1892. Serial No. (N0 modem T0 at whom it may concern:
Be it known that 1, JAMES H. WATT, of Barnesville, in the county of Belmontand State of Ohio, have invented certain new and useful Improvements in Self Oiling Car- Wheels; and I do hereby declare that the following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.
This invention is an improvement in self oiling wheel-hubs, especially designed for coal car wheels, and whenever the wheels are revolubly mounted on their axles; and its object is to insure the greatest supply of lubricant at the point where the greatest friction or wear is engendered, to wit-at the buttof the wheel-hub, and spindle, and what I consider original in my Wheel hub is that it has two or more oil-holding chambers instead of one, and permits the oil to pass over the axle right at the butt of the hub. The point of the axle is always well lubricated, but it is not so with the butt of the wheel, and my wheel overcomes that difficult-y. There being two boxes instead of one adds very materially to the strength of the wheel and will allow much less iron in the hub to get the desired strength.
Another very great advantage which I claim is, that there being a wall between the boxes therefore the oil cannot so freely flow over the spindle when the wheel is idle and therefore it will be better oiled when again started after a short stop.
The invention therefore consists in the novel construction of the wheel as hereinafter described and illustrated in the drawings, in which- Figure l is a transverse central section through a wheel-hub embodying my invention. Fig. 2 is a vertical sectional view on line 2-2 Fig. 1. Fig. 3 is a front view.
The hub A of the wheel is cast with an annular series of closed chambers B, B, two only being shown, separated by radial partitions C, 0, so that there is no direct communication between said chambers. Through the front wall'of the hub are openings 0 through which said chambers can be filled with lubricant and a cap D is bolted to the front end of the hub as indicated so as to cover said openings. Said cap has a central, opening (1 and the oil can be poured therethrough into the cap and thence pass into the chambers substantially as described and shown in my patent No. 234,098, of November 2, 1880. At the butt end of the hub are transverse slots 1), one at the rear end of and communicating with each chamber B, and through these slots the lubricants can escape from the chambers and onto the spindles at the butt and larger end thereof where the greatest friction and wear usually take place, the lubricant working downward on the spindle, and fully lubricating the whole hub bearing.
It will be seen that my wheel contains two distinct oil chambers that are in no wise connected in the hub. The openings in the outer wall of the wheel permits the oil to flow into either one of them or both at the same time when the wheel is in the proper position to receive oil in both at the same time. I look upon this as quite an advantage in a wheel. There being two separate chambers, the axle is much more likely to be immersed in oil than when there is but one. By this device the oil is forced to strike the axle right at the hub and butt of the wheel, and the point is always oiled as that is where the oil enters from the chambers.
My observation in self-oiling wheels for many years teaches me that in the ordinary construction of self-oilingwheels the oil flows off too easily and escapes into the lower part of the box, but this invention prevents this to a very great extent. The oil is supplied near the butt end of hub and largest part of spindle, instead of near the center or small end. This arrangement of chambers allows the hub bearing on the spindle to be almost continuous, and the partitions form strong braces to reinforce the bearing portion of its hub.
Having described my invention, what I claim as new, and desire to secure by Letters Patent thereon, is-
A self oiling hub having an annular series of non-communicating oil chambers around its bore, and transverse slots at its butt end about as long as the chambers are Wide es- In testimony that I claim the foregoing as tablishing communication between its bore myow'nIaifixmy signature in presenceof two IO and said chambers, and partitions between witnesses.
said chambers openin s in the front end of 1r 5 hub communicating with said chambers, and JAMES a cap secured thereon, all constructed and ar- NVitnesses:
ranged to operate substantially as and for the W. E. SMITH,
purpose described. E. M. VAN CLUEE.
