UNITED STATES WILLIAM E. HARRIS, E NILES, oIIIo.
PATENT OFFICE.
ROLL FOR METAL-ROLLING.
SPECIFICATION forming part of Letters Patent No. 517,74*?, dated April 3, 1894.
Application filed February 8, 1893.. Serial No. 461,416. (No model.) l
.To a/ZZ whom it' may concern.-
Be it known that I, WILLIAM E. HARRIS, of Niles, in the county of Trumbull and State of Ohio, have invented a certainnew and useful Improvement in Rolls for Metal-Rolling, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specitication.
My invention relates to an improved roll for metal rolling. Y
My inventionconsists'in features of novelty hereinafter fully described and pointed out in the claim.
Figure I is a vertical, longitudinal section, taken through the center of the mold and tube. Fig. II is a central, longitudinal section through the mold and chill, the roll being shown partin section and part in elevation. Fig. III is a plan view 'of a finished roll -and illustrates a modication. Fig. IV is a longitudinal section, taken on line Il-II, Fig. III.
Referring to the drawings, 1 represents the top, and 2 the bottoni of the sand mold, and 4 the -space within the mold. 5 represents a gate through which the metal is poured.
The mold is set on end, and the steel or ironY tube l1, after being heated, yis placed within the center of the mold, one end of which isv allowed to rest in the bottom 2 of the mold,
outer shell of the roll.
and the other end to project up and through the top l of the'mold, which affords easy access to pour moltenmetal in the tube, at the same time that the molten cast iron is poured through the gate 5 into the mold toform the The metal is poured until thetube and mold are full, which will' give a full sized roll. f
-If I wish to produce a roll twenty-four inches in diameter, I take a tube say eight inches in diameter, and till it with steel, and
cast all around it eight inches of cast iron, which will give, as will readily be seen, a solid roll much stronger, less liable to crack, than if all made of cast iron twenty-four inches in diameter, or the size desired. A roll thus formed possesses great strength, while having all the advantages of an ordinary roll.
In Fig. II I have shown one means by which the face of roll may be chilled. In this iigure 8 represents the body of the roll, 9 0E- sets orsteps which form the journals Vof the roll. The journals I prefer to have cast in sand, Afor the reason that ifl their diameter need be reduced, it can be readily accomplished by turning them down to the desired diameter, Whereasif they were cast within a chill, the diameter would necessarily have to remain as cast. 10 represents an outer ring or chill, made the length of the face'part 8 of the roll, Whatever length said face may be.
In Fig. IV I have shown a modification of vthe internal tube, in which 13 represents a tube equal in length to the body ofl the roll and of greater diameter than the tube 14 within` the journal. f
It is quite obvious that the difference in the 'diameters of the tubesis to equalize thedifference in the shrinkage of the metals.
-. vI am aware that itis not broadly new to construct a composite roll of cast-iron and caststeel, but I am not aware that such acomposite roll of the construction set -forth in my claim has ever before been known or'used.
I claim as my invention- A roll comprising a steel core, a cast iron Vbody and journals, and a tube extending the
