UNlTEEU STATES JAIYIES CAREY DAVIS, OF HINSDALEILLINOIS.
MOLD.
Specification of Letters Patent.
. Patented Nov. 23, leis.
Application filed February 21, 1911. Serial No. 610,015.
To all whom it may ij'oncern Be it known thatl, JAMES CAREY DAVIS, a citizen of the United States, and a resident of Hinsdale, in the county of Dupage and State of Illinois, have invented certain new and useful Improvements in Molds, of which the following is a specification.
My present invention relates to molds use ful in the art of casting metal in general,
more particularly to metallic molds, and
especially to the provision of improved means whereby a casting of uninterrupted periphery, and free from cracks may be produced in an iron mold.
The principal objects of my present invention are the provision of an improved form of mold, and more particularly, an iron mold, which I find in practice generally useful in the casting of bodies having relatively large centers and peripheral portions and relatively thin intermediate portions, and specially useful when such bodies are made of cast steel which has a'tendency to crack peripherally when cast in metal molds, such molds being especially desirable 'for the production of cast steel wheels and like structures wherein not only tread cracks, but also flange cracks, as well as fractures in the surface are particularly to be avoidedg together with such further objects as will hereinafter appear.
In the production of cast steel wheels and other structures by apparatus and processes heretofore known to me I have experienced great difficulty in utilizing iron molds having circular or rounded portions or relatively thin portions for the production of steel castings, owing to the tendency, of the steel to cool so rapidly that cracks develop on such. circular or rounded portions or in such relatively thin portions.
In accomplishing the foregoing objects,
and overcoming the disadvantages referred to, and in attaining certain further benefits to be below disclosed, l have provided the constructions illustrated in preferred form in the accompanying drawings, wherein- Figure 1 is an velevational view, partly in invention; Figs. 2 and 3 are respectively an:
der'and top plan views of the cope of the mold of Fig. 1; Fig. l is a top plan view of, 2
nnldrag used in forming of the mold of Fig.
l, and Figbris under planyiewbfffthecheek ring used in connection with the mold of Fig. 1.
Referring now more particularly to Fig.
1 it will be observed that I have here illustrated a form of mold comprising a cope 1,
a drag 2 and an intermediate cheekipiece 3 which I find specially useful in carrying out my invention, a wheel being here indicated for purposes of convenience, the, center, tread, and corrugated flange being respectively indicated at if, 5 and 6, and the, cope 2 being gated at 7 and provided with a sand core as indicated at 8, sand cores also being provided at 9 and 10 to allow the formation of narrow necked risers which maybe readily broken away. In pouring such structures in an ordinary mold I have found-that the tread 5 cracks transversely, but that by providing the cheek ring 3 with sand inserts 111l arranged at intervals transversely of the tread l have found that the wheel cools moreslowly and without surface cracks in such tread, though the other advantages of the use of an iron mold remain.
In using iron cope and drag members in the usual manner, or even in connection with the improved form of cheek piece 3 with sand inserts I have found that the web cracks radially, especially at the highest and lowest points of the ,corrugationa'mdiproduce in an iron mold 'a'steel wheel entirely free from cracks. x v
While I have illustratedmy nvention in *conneetien with a. mold available for, the
manufacture ofwheeis, and believethat it igparticularly useful for the production of vertical section, of a mold embodying my suche i j s and others wherein'it is espe ciallyadesira'ble to have freedom from cracks my,.inve 'tion is obviously useful in'the- .3 ananufacture of. other castingm. I

4:. In a' casting apparatus, a mold comprising metal cope and drag portions, one provided with a check portion having a substantially rounded inner periphery provided with spaced sand inserts extending transversely of such periphery.
5. In a casting apparatus, a .car wheel mold comprising metal cope and drag por tions each provided with adially arranged sand inserts.
6. Ina casting apparatus, a car wheel mold comprising metal cope and drag portions each provided with radially arranged sand inserts, the inserts in the cope being arranged in alternation with those in the mold comprising a cope, a drag, and a check portion, said cope and drag being provided with radial arranged sand inserts, andsaid check portion with sand inserts.
9. In a casting apparatus, a car wheel mold connn-i 'ng' a cope, a drag, and a cheek portion forming a mold cavity, said cope and drag being provided with sand inserts extending from adjaceat theperiphery of the mold cavity toward the center thereof,
v and said check portion being provided with sand inserts.
10. In a casting apparatus, a car wheel mold comprising a cope and a drag forming a mold cavity, said cope and drag being provided with sand inserts extending from adjacent the periphery of the mold cavity toward the center thereof.
11. In a casting apparatus, a car wheel mold comprising a cope, a drag, and a cheek portion forming a mold cavity, said cope and dragbeing provided with sand inserts extending from. adjacent the periphery of the mold cavity toward the center thereof and said cheek portion being provided with said inserts arranged transversely thereof.
12. In a casting apparatus mold having a curved or rounded surface of metal, and an exposed metal surfacc'arranged at an angle thereto, said first mentioned surface being provided with a plurality of spaced sand inserts severally extending transver v thereof substantially the width of said surface.
In a casting apparatus a mold having a curved or rounded surface of metal, and an exposed metal surface arranged at an anglev thereto, said last mentioned surface being provided with a plurality of spaced sand inserts severally extending trans-- verscly thereof substantially the width of said surface. In testimony whereof I have hereunto signed my name in the presence of the two subscribed. witnesses. Y
