IMPROVEMENT IN IRON-ROLLS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, SAMUEL J. SEELY, of the city, county, and State of New York, have invented anew and useful`Improvement in Rolls forRolling Iron, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of' this specification, and in which-1- Figure 1 is a view in elevation of one of my improved rollers. I

Figure 2 is an end view ot' the roller. i A

Figure 3 is au end view of the arbor and sections or dies, separated; and y Figures 4, 5, and 6 are an outside, Yan inside, and an end viewiof a single section or die-of the roller.

Solid rollers for rolling iron are expensive, and diilicult to least sound, and when injured in part are only' valuable as old iron, or te be reduced in diameter and used as smaller rollers; and to produce the various forms in which iron is used, they are required in great numbers, involving capital that is much ,of the time idle.

Now, it is the object of my invention to obviate theseohjections .to solid rollers for rolling iron by forming a roller of sections or dies of cast iron upon a wrought-iron arbor; and to this end my invention consists in` forming the arbor or journals for rollers for rolling iron of wrought iron of a polygonal shape, the sides of which are all depressed on one edge and raised `on the other, so that each angle shall be raised to a shoulder` on e. line radiating from the axis to the perimeter of the roller, while the sides and angles of thearbor are parallel Ate its axis, and covering the arbor with removable dies or sections of wrought iron matched to and firmly secured upon the sides ofthe arbor, and reduced to the form' desired for rolling iron of any design or pattern.

In the example employed in this specificationv to illustrate my invention, I form a hexagonal arbor, A', of wrought iron, soundly forged, with the journals B and C truly turned upon accurate centres. From these centres a circle is described upon the end of the arbor A, which is divided into six equal parts by lines-radiating fromv the axis ofl the arbor. .Between these radiating lines, and in the largest circle of which the arbor will admit, I project planes orsides 1, 2, 3, 4, 5, and 6, depressing o'ne edge of each plane, so that the oppositev edge shall form at the angles shoulders 7,- 8, 9, l0, 11, and 12. I now reduce'these sides and angles longitudinally across the arbor, in lines truly parallel with its axis, finishing the surface, if necessary, with the plane accurately applied.

I have described the shoulders ofthe sides of this hexagonal figure us formed on llines radiating from the centre ofthe arbor, and so formed they will he found eicient to sustain the pressure of the blocks or dies when secured imposition. But it may be found expedient to change the face of these shoulders, so as to form a dovetailed shape, and let the dies be formed with a corresponding projection, so that when secured upon the arbor the dieser sections shll be locked thereto by a dove-tailed connection which will render them even more secure than when fastened as first described. When the arbor is finished, I build the roller up of dies 13, 14, 15, 16, 17, and 18, all formed on their inner sides to match the sides 1, 2, 3, 4, 5, and 6 of the arbor, each die having-.one

edge resting behind one ofthe shoulders 7, 8, 9, 10, 11, and 12, while the angular sides or edges e andf(g. 6)

ofthe dies or sections are reduced truly in lines to form an laccurate circle upon the arbor. These dies are made of cast iron, and plancd to a perfect fit on their inner sides and edfres, and may be of the whole length of the roller, or divided into short pieces. But in whatever lengths they are made, they must, it is manifest, be firm-ly fastened to the arbor; and the fastening 'may be effected by screws through the dies, or otherwise; and where the dies are as long as the arbor, the ends may be turned down and banded, and this fastening, with the dore-tailed connection before described, will be found all-suihcient in all short -rollers.

In fig. 4, one ofthe sections is shown with its outer surface ut D, and its inner surface at E, fig. 5, with an end view at F, fig. 6. After the dios oi sections I3, 14, 15, 16, 17, and 18 are thus fitted and securely fastened tothe arbor, the surface of the roller G may be reduced in any of themost approved methods, and finished to such form as may be desired for any description of rolled iron.

r1`hus formed, the arbol' of my roll will hc liable to little wear, sure on the journals, where all rolls must' wear much alike under like conditions'. The sections can be changed with little delay, and a broken or worn one replaced without materially injuring the roll. The sections are cheaply made, and few arbors and housings will be required iu the conduct of large business, for 'thedcsign of' the sections only will require any change to produce a. variety of forms in the iron to be rolled, while `there can be no loss in liability to break from defective casting, as in the large heavy rolls of cast iron.

I have only described a. hexagonal roller, but of course it is Well understood hat my arbor may be mudo with more or fewer sides and projcctionswvithout departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is

A roll for rolling. iron, having a, solid Wrought-iron arbor and asectionol east-iron surface, when constructed substantially in the manner described, forl the purpose set forth.

In testimony whereof, I have hereunto subscribed my nume.
