SAMUEL I. BUSH, OF COLUMBUS, OI-IIO, ASSIGNOR TO THE BUCKEYE STE-EL CASTINGS COMPANY, OF COLUMBUS, OHIO.
METHOD OF MAKING CARP-WHEELS.
Specification of Letters Patent.
Patented July 28, 1914.
Application filed December 22, 1913. Serial No. 808,230.
To all whomit may concern Be it known that I, SAMUEL P. BUSH, of Columbus, inthe county of Franklin and State of Ohio, have invented certain new and useful Improvements in Methods of Making Car-Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.
My invention relates to an improvement in method of making car wheels, and it consists in casting the wheel of greaterdiameter than the finished wheel, and the rim of the wheel of less thickness than thefinished rim, and of a. size best adapted for the production of a perfect casting, and subsequently increasing the thickness of the rim and decreasing the diameter of the wheel by rolling or forging.
The accompanying drawing is a view in section showing in full lines the wheel as cast and in dotted lines the finished wheel.
In the manufacture of the wheel, the latter is cast of greater diameter than the finished wheel, and the plate or web 1 thereof, is distorted as shown in full lines in the drawing, the hub 52 being preferably cast in finished size and shape, except for any machining as may be necessary for its proper attachment to the axle. The rim 8 of the wheel, as cast, is of less thickness than the rim of the finished wheel as shown in dotted lines. The object of casting the wheel of greater diameter than the finished wheel, and the rim of lesser thickness than the rim of the finished wheel, is, that, experiments have demonstrated that a more perfect casting can be produced with less cost in a thin rim than in a thick one, and by distorting the plate, or web, some surplus metal is provided from which the thickness of the web may be slightly increased by the subsequent forging steps. After the wheel has been'cast as shown in full lines, it is forged, by rolls orotherwise, so as to flatten, or lessen thedistortion of the plate or web 1, and reduce the-diameter of the wheel,
which results in a thickening up of the rim as shown in dotted lines, and possibly some thickening of the web or plate. This forging of the wheel, after casting, improves the metal in the rim, and particularly so as the forging in this particular instance subjects the metal in the rim to a compressive force rather than a stretching one.
In casting the wheel blank, the rim need not be as wide as the finished rim, and the flange 4: may be smaller than the flange on the finished rim, as these parts can be filled out during the forging or rolling process.
If desired the hub and web may be cast of metal of one kind, and the rim of an other kind, both kinds being specially adapted for the purpose'of the service intended, as fully set forth in Patent No. 1,086,138 granted to me February 3rd, 191%, but I do not limit the present invention to the use. of two metals, as satisfactory results may be accomplished by the use of one metal only.
Having fully described my invention what I claim as new and desire to secure by Letters Patent, is
1. The process of making a car wheel, consisting in casting a wheel blank of greater diameter than the finished wheel and forging the blank to reduce'its diameter.
2. The process of making a car wheel consisting in casting a wheel blank of greater diameter than the finished wheel, and subsequently reducing its diameter and increasing the cross sectional area of the rim.
3. The process of making a car wheel consisting in casting a wheel blank of greater diameter than the finished wheel, and with its plate or web distorted, and forging the blank to reduce its diameter, increase the cross sectional area of the rim, and impart final shape to the distorted plate or web.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
SAMUEL, P. BUSH.
