Description
PATENT Fried WILLIAM A. MILES, OF OOPAKE IRON WORKS, NEW YORK.
IMPROVEMENT IN CASTING CAR-WHEELS.
Specification forming part of Letters Patent N 0. 159,434, dated February 2, 1875 application filed September 16, 1874.
CASE D.
To all whom itwnay concern:
Be it known that 1, WILLIAM A. MILES, of Oopake Iron Works, in the county of Columbia and State of New York, have invented new and useful Improvements in Process of Attachin g Tires to Car or Locomotive Wheels; and I do hereby declare that the following is a full and exact description of the same, reference being bad to the accompanying drawings and to the letters of reference marked thereon.
This invention is a novel process of uniting tires to car and locomotive wheels, consisting, essentially, first, in making the tire and central portions separately; second, heating these parts; third, introducing between them a stream of molten metal fourth, causing the same to flow (JOIltlllllOllSljIlllllill the adjacent faces of the independent parts are fused, substantially as will be fully described hereinafter.
Figures 1, 2, and 3 represent sectional elevations of wheels and tires, illustrating my improved process for uniting them.
To enable others skilled in the art to make and use my invention, I will now proceed to fully describe its construction and manner of operation.
A represents the tire, constructed generally in any proper manner, and of suitable material, but preferably of rolled steel, which is provided with the inclined inner face, a, and inner circumferential groove or key-seat, a, as shown. B represents the central portion of the wheel, also constructed generally in any proper manner and of suitable material, but preferably of cast or wrought iron, which is provided with the inclined outer face, 6, and outer circumferential groove, b as shown. If desired, a single circumferential groove in each of the parts may be employed, as shown in Fig.1, or two or more, as shown in Fig. 2. 12 represents suitable pouring-sprues in the central portion of the wheel, which communicate with the grooved opening, as shown, by means of which molten metal may be conveyed to the groove. b represent suitable exit-sprues, adapted to permit the molten metal to flow out of the wheel, in order that a constant stream may flow through the groove until the adjacent parts are fused. These sprues are cast with the central portion, and removed after the wheel is finished.
The manner of employing my improved process is as follows: The parts having first been separately cast in the manner described, and heated in a proper furnace to a bright red heat, and placed together, as indicated in the drawing, pressure may be applied to the central portion to bring it down to its place, and hold it there while the operation of pouring is efi'ected and until the metal hardens. Molten metal at a high temperature is then, by means of the entrance and exit sprues, caused to flow in a constant stream through the groove or grooves until the adjacent parts are fused, the sand serving to protect the wheel from injury by the outflowin g metal, as indicated in Fig. 4.
It will thus be understood that the parts are not only welded together by the fusion of the adjacent surfaces, but that the welding metal, when cold, also forms a key, which securely locks the parts together.
I am aware that there are other processes of welding or uniting a metal tire to a metal cen- {er, and do not, broadly, claim such a result; iut
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The described process of constructing carwheels consisting, essentially, first, in making the tire and central portions separately second, heating these parts; third, introducing between them astream of molten metal; fourth, causing the same to flow continuously until the adjacent parts are fused, substantially as described.
This specification signed and witnessed this 14th day of September, 1874.
