ROLLING-MILL..

SPECIFICATION forming part of Letters Patent No. 392,484, dated November 6, 1888.

Application filed Sepiember 27, 1888. Serial No. 286,579. (No model.)

' have invented a certain new and useful lmprovement in Rolling-Mills for Iron and Steel, of which the following is a specification.

My improvement in rolling-mills relates to the construction ot' the rolls themselves. The roll I have devised is what may be termed a compound universal mill-roll, and itis composed, essentially, of a steel axle, steel rings, (corresponding to the collars or flanges of the ordinary millroll,) and cast-iron rings, which form the channels or grooves between said collars, these steel collars and east-iron channelrings being indvidually removable and adjustable.

The invention depends for its novelty as well as its practical value upon the fact that the roll is a compound one, made up of steel and castiron parts so constructed and coinbined that each new section or shape of bar or other iron to be rolled requires the change of the cast-iron parts ofthe roll only, these parts being so arranged that they can readily be removed and replaced by others. By the use of these interchangeable cast-iron parts the same rolls can be used for rolling iron of any sectionmbar, i'lat, angle, &e.

In the accompanying drawings I have represented a pair of such compound universal mill-rolls for rolling bar-iron.

Figure l is a front elevation of the rolls. The remaining three figures represent iu section and elevation such of the steel collars and east-iron channel-rings as are needed in order to fully explain the construction of the rolls.

Each roll consists of the following parts:

First. A. steel axle, a, provided with journals, necks, the., as is the case with ordinary rolls. Ou that portion of the axle between the journals is formed at one end a collar or shoulder, b, integral with the axle, and at the other end a screw-thread, d. The axle is further provided with a longitudinal spline or key, which extends throughout the whole length of the axle between the collar b and the screwthread d.

-ous face of the nut.

- Second. Steel rings c. (Shown separatelyin elevation and section in Fig. 2.) These rings correspond to the collars or flanges which in ordinary rolls bound the channels or grooves through which the bar-iron is passed. They lit upon the axle closely and have inner notches or grooves, x, to take upon or engage the spline or key on the axle. The end ring, c', has in the face which adjoins the collar Z an annular recess, y, Fig. 3, in which the collar b fits.

Third. Cast-iron rings e, which alternate with the steel collars c and correspond to the grooves or channels of ordinary rolls. They tit closely upon the axle and have notches x to engage the spline or key thereon. One of these rings is shown in section and elevation in Fig. 4L. It is these parts which are changed or replaced by other cast-iron rings of different shapes, according to the section of iron to be rolled.

Fourth. A steel nut,f, screwing upon the screw-thread d for tightening the sections, and

a steel covering-ring, g, which has two pins that enter corresponding holes in the contigu- This covering-ring proteets the nut and keeps it from rubbing against the housings. In ease the sections do not till up all the space between the collar b and the screw-thread d, additional cast-iron rings or washers may be used for this purpose, the same being interposed between the nutj and the end collar, c, next adjoining the nut.

Some ofthe advantages obtained by my invention may be stated as follows:

First. The main expense of my compound roll is in the iirst cost of the steel axle and steel collars, which is, say, about two hundred and fifty dollars per pairof rolls; but such axle and collars can then be used for rolling bars and sections of any shape, all that is required being to change one set of cast-iron rings, e, for another set of a shape suitable to furnish channels or grooves of the desired shape. rlhe cost of a full set of such east-iron rings is, at the outside, from one hundred dollars to one hundred and twenty-five dollars per pair of rolls. lVhen it is considered that the cost of a pair of the ordinary cast-iron rolls of the saine dimensions is about two hundred and fifty dollars, and that it is necessary to have a separate pair of such rolls for each different IOO shape or section of iron to be rolled, the saving effected by my invention is obvious, because I can use the same steel axle and collars with any number ofinterchangeable sets of 10 renee with the ordinary east-iron rolIs-and there is less wear of the journals.

Third. The expense of changing,` or replacing a east-iron ring, if broken, is small.

Fourth. As eaeh east-iron ring is east sepa- 15 rately its rough dimensions eau be made to approximate closely those required for the finished ring, so that the cost of finishing is eomparativel y little.

Fifth. The east-iron rings for the finishing` zo grooves or channels ofthe rolls ean be readily hardened or chilled, which it is very difficult to do in the ordinary solid east-iron rolls.

Sixth. rllhe rings, when damaged or broken,

can be readily remelted in a eupola, whereas,

on the contrary, large and expensive furnaces are required for remelting,` ordinary rolls.

Seventh. Butlittlespaeeis required for storing the rings when not in use in comparison with the extensive yards required for the storage of the ordinary east-iron rolls.

Having described my improvement in rolling-mills for rolling,` iron and steel and the best way now known to me of carrying,|` the same into practical el'feet, what l claim herein as new and of my own invention is- A compound mill-roll for rolling iron and steel, consisting, essentially, of a steel axle, in combination with separate and removable steel collars and east-iron ehannel-rings mounted thereon, substantially as and for the purpose hereinbefore set forth.

In testimony whereof Ihave hereunto set my hand this 6th day of September, A. D. 1888.
