CASTING CAR-WHEELS.
SPECIFICATION forming part of Letters Iatent No. 283,311, dated August 14, 1883.
A pplication filed July 10, 1853. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM WILMINGTON, of Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Improvement in Casting Car-Wheels; and I do hereby declare that the following is a full,
clear, andexact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which the figure is a vertical central section of a car-wheelmold used in carrying out my invention. a
This invention is an improvement in the method of casting car-wheels,'the object of which is tomodify the chill-hardening qualities bf the iron forming the central parts of the wheel. I-Ieretofore I have practiced different methods of modifying the chilling quali- H ties of the iron forming these parts of the mold, or in a pouring-ladle, finely-powdered wheel by placing in the receiving-basin of the ferro-manganese, or its equivalents in other powdered metals, the same to be melted'by contact with the molten iron in the basin or in the ladle, and conveyed into the mold bydifl'erent methods, to be diffused through the molten iron forming the central portions of the wheel. These different methods have produced very beneficial results upon the carwheels, but are attended with much cost and delay when casting the wheels.
To lessen the cost and time when casting I the wheels, and prevent the'molten iron forming the hub and inner plates of wheels from becoming too hard and rigid by coming in contact with the cold compact cores and moist sand of the mold, is the object of my invention.
It consistsin affixing to the desired portions of the outersurfaces of the cores of the mold, by suitable adhesive compositions used. in
foundry-work, about a half a pound of very finely powdered ferro-manganese having a large per cent. of carbon and silicon in its composition, allowing the same to be melted by the molten iron which comes in contact with the ferro-manganese when the mold is being filled, which ferro-manganese, being melted,
will be diffused through the hub and :inner plate parts of the wheel, thereby modifying the chilling qualities of the iron forming these parts, and preventing the same from-being too hard and rigid. To accomplish this same re sult in modifying the chilling qualities of iron in these parts of the wheel, I use, instead of geleisen having a large per cent. of carbon, silicon, and manganese in its composition. Of this metal I use larger portions than the former. r
In single-plated car-wheels,instead of affixing all the ferromanga-nese to the core, I coat the inner surface of the upper and central parts of the mold with the dust or very finely powdered ferro-manganese by sifting said dust through the meshes of suitable cloth, then causing the same to adhere to the sand of the mold by passing a tool over the same, which I do not confine myself to the use of the ex the spiegeleisen, nor do Iconfine' myself to the use of the above-named metals alone, but use metalloids having large portions of carbon, silicon, and manganese in their composition, and I may use each singly or in combination .the best results upon the car-wheels.
In the drawing, letter A is the receivingbasin, B the central core, and .0 the core of the plates. The dotted lines a b show where the ferro-manganese is attached to the cores by a preparation of water, glue, flour, or .1110 lasses, as may be desired.
I disclaim as my invention the alloying of molten iron or steel with ferro manganese, spiegeleisen, or cast-iron derived from argillaceous or black band iron ores when the same is melted in a furnace cupolaor crucible, for this is common.
melting by contact with molten iron in aladle or in the receiving-basin of a car-wheel ferromanganese, spiegeleisen, or cast-iron derived from argillaceous iron ores, and causing the melted metal bydifferent methods topenetrate downward into the mold of a car-wheel, for this has heretofore been practiced.
What I claim as my invention isferro-manganese, very finely powdered spie-' is termed in foundry-work sliking. i
