SAMUEL P. BUSH,
OF COLUMBUS, CHIC), ASSIGNOR TO THE BUCKEYE STEEL GASTINGS COMPANY, OF COLUMBUS, OHIO, A- (3ORP lfJlfl/A'lION".
METHOD OF MAKING CAR-"WHEELS.
Specification of Letters Patents Patented Feb, $1914 Application filed February 28, 1913. Serial No. 751,373.
To all whom it mqy concern:
Be it known that I, SAMUEL P. BUSH, of Columbus, in the county of Franklin and State of Ohio, have invented certain new ed for the purpose of the service intended,
and is designed particularly as an improvement on the method disclosed in Patent No. 1,047,378, granted to me December 17th, 1912.
In the patented method, the hub and part of the web as they come from the mold are elevated above normal position of these parts in the finished wheel, and the wheel is subsequently shaped by forcing the hub down into position thus shortening up the web and compressing and compacting the latter and also the hub and rim.
The present invent-ionv consists in casting the hub and rim of the wheel in their proper relative positions, and the web distorted, so that in the final shaping ofthe web, the latter will be shortened up and the parts compressed and made more compact.
The accompanying drawing is a,-view in section showing in full lines t he'wheel as cast, and in dotted linesv the web after the latter has been reshaped In car wheels it is essential that the flange l of the rim 2 shall be in a plane 3 passing through the hub 4 of the Wheel, and the outer end of the hub in a plane intermediate the planes 3 and 5. In the present method the hub 4; and the rim 2 are cast in their properrelative positions, and the web is distorted, preferably by an upward bend 6 therein as shown.
In pouring the molten metal into the mold, the metal for the rim may be introduced through the center of the hub core,
and up through the hub to the web and down the latter to the rim so as to wholly or partly fill the same,'immediately after wh ch the metal for the web and hub may be introduced in the same manner, or if, desired, the metal for the rim may be poured directly into the latter through a suitable gate,'while the metal for the hub and Web are being poured into the hub or into the latter through the hub core. If the metals are poured one after the other, there should not be. any material delay between the pooring steps, so that as the metals meet they will unite while in a fluid condition. The metal poured into the hub, forces the fluid rim metal within the web into the rim until the latter is filled. By either method of pouring the two metals are kept reasonably distinct, hence the rim of the wheel is, when finished, composed of metal best suited to sustain the wear and friction to which the rim is subjected, while the hub and web are more malleable and of a metal that may be readily machined.
After the wheel has been cast, and preferably while it is at a forging temperature, I support the rim and hub so as to prevent any change of their relative position, and roll, press, or swage the web'from its"-,distorted position as in full lines, to its final position, as in dotted lines. This shortcut ing of the web not only compresses and compacts it, but it also more or less compacts the rim and hub and tends to obliterate any shrink or blow holes that may be within those parts. By shortening up the web, it will be relieved of all stresses due to shrinkage.
Havingfully described my invention what I claim as new and desire to secure by-Letters Patent, is
1. The method of making car wheels consisting in casting the hub and rim in their proper relative position and the web distorted, and subsequently shaping the web into final position for shortening same.
2. The method of making ear wheels conspecifioation in the presence of two subscrib sisting in casting the hub and rim in their 1 d h b mg Witnesses. proper re ative position an t e we disv torted, and subsequently shortening the Web SAMUEL BUSH by shaping it into final position While the Witnesses:
Wheel is at a forging temperature. GEO. G. WERRING,
