ACHARLES H. MORGAN, OF WORCESTER, MASSACHUSETTS.

SQECIFICATION forming part of Letters Patent No. S34-,454I dated January 19, 1886.

Application filed November 28, 1885. Serial No. 184,200. (No morleLl To all whom it may concern,.- l

Be it 'known that I, CHARLEs H. MORGAN, of Worcester, in the count-y of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Wire-Rod- Rolling Mills; and I do hereby declare that the following is a full,` clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figure l represents a top or plan View of my improved rolling-mill; and Fig. 2, a vertical longitudinal section of the same, taken on the line A B, Fig. l, looking. in the direction indicated by the arrow, same tigure, also showing parts of the mill inside view.

My inv ention relates to rolling-mills for rolling wire rods directly from fluid or molten metal; and it consists in the combination, with a continuous train of reducing-rolls,of a suitable apparatus for reducing scrap or pig iron to a molten state, refining the same, then conducting said molten metal to a pair of cooling and forming rolls` thence to the reducing-rolls aforesaid, said metal being cooled to a temperature just below a molten state in any suitable manner prior to entering the formingrolls above referred to, cut apart as required after leaving said forming-rolls and prior to entering the reducing rolls, and the waste caught underneath by suitable means, hereinafter more fully described.

It also consists in the combination of the parts aforesaid with suitable reeling devices, conductingfpipes, and one or more supplementary sets of reducing-rolls, substantially as hereinafter set forth.

In the accompanying sheets of drawings, Figure 1 shows a plan View. Fig. 2 shows a side view, partly in section.

In the drawings, O represents an ordinary train ofreducing-rolls,provided with the usual guides, C', for conducting the rods from one set of reducing-rolls to another in the process of reduction.

rIhe part markedv D represents an ordinary cupola, provided with the usual means -for melting the scrap or pig iron contained there- .,in, and with the outlet D at the bottom, for

tapping77 said molten metal when required for use, as hereinafter described.

E represents a crane, having an ordinary Bessemer converter, E', mounted upon the outer end of its swinging arm E2, and made hollow for conducting an air-blast to said converter, said arm also being fitted to turn on its bearings, and provided with means whereby said arm and its converter are turned when required, as hereinafter more fully explained. The purpose of said crane and converter is to transfer the molten metal in the cupola D to the receiving-ladle F, being refined in said converter by the usual Bessemer process. The upper part, a, of the crane E is fitted to slide up and down in the frame or base b, being op erated by turning the hand-crank c by means of the usual mechanism contained within said vertical base part b. Said parts c and b are so constructed as to admit ofthe passage of the air-blast hereinloefore referred to up through the crane to the converter E thereof. The part a not only moves vertically, but also turns in its bearing, so that the arm E2 may be swung around to conduct the converter from the cupola D to the receiving -ladle F, and vice versa, as required in transferring the molten metal from the former to the latter. The converter is tipped, as required in performing said operation, by means of a hand-crank, g, through the crank-shaft h, turning in suitable bearings, and provided at its upper end with the threaded part It', which meshes with the worm-gear on the arm to which said converter is attached. The receiving-ladle F is provided at the bottom with a suitable outlet and tube, j, converging inward toward the bottom, through which the metal passes prior to entering the forming-rolls It 7c, arranged to turn just under the same.

In order that the molten metal contained in the ladle F may be cooled sufficiently to mold the same in passing between the formingrolls k, and yet not unduly retard its progress downward through the tunnel-shaped tube j, I arrange a suitable number of pipe-coils, Z, around the same, through which may be passed a current of cold water or a steamblast,fapplied in any suitable manner. I do not limit myself, however, to this method of cooling, as various ways may be adopted to effect the same result.

The temperature of the metal in the receiving-ladle F is maintained and controlled byapplying a hot-blast to the top thereof, produced by the use of petroleum or other hydrocarbon, forced through the blast-pipe IOO in and into said metal by means of superheated steam or air.

Previous to pouring the first charge from the converter E into the ladle F the bottom opening of said ladle is closed by means of a plug, n, operated by a rod extending up therefrom. The ladle having been tilled, said plug is then withdrawn, thus allowingr the metal to ilow down through the tube j and. between the rolls k L' intethe receptacle p. W'hen the metal has arrived at the proper consistency to pass it into the continuous train C, it is cut apart, as iteontinues to tiow down, by

means of a suitable cutting device arranged under the forming-rolls 7a 7J, the free end being then caught by an attendant, by means of suitable tongs, and fed in between the'tirst setof reducing-rolls of the continuous train C, which then carries it along through the different stages of reduction in the usual way. In this instance I cut the metal apart,as aforesaid, by means of the rotating cutters 0, hav ingthe cutting-edges o, which,when they collie together by the rotation of said cutters, act as shears to sever the metal. .Said cutters may be operated, as required, by any suitable and convenient means. As the metal leaves the last set of rolls ofthe continuous train C, it enters and passes through a stationary conducting-pipe, I-I. thence into and through a rotating pipe, H, and is distributed in the stationary reel G around the central cone, G', thereof. Said reel is arranged in a suitable inclosure of tire-brick, in which a fire may be kept up, it' necessary, to maintain o1' increase the temperature of the metal deposited in said reel as aforesaid.

the distributing-pipe II is operated by a driving-shaft, I, (driven by any suitable means,) through the spur-gears I and I, which work together, the pipe H being arranged in the gear I, and both of said gears fitted to turn in the frame J.

If desired, the rods deposited in the reel G may be still further reduced in size by passing them through one or more sets of supplementary rolls, C2. In removing the same from the reet one end of the rod is drawn up through the central opening in the gear I, (the pipe H having been previously removed,) and thence over the friction-roll q to said supplementary rolls. The friction-roll 1 is fitted to turn in a suitable bearing, r, which may in turn be fitted to rotate, if desired, to facilitate said drawing-oil' operation.

It will be understood that the rolls k and those ofthe continuous train C are constructed and titted to turn in the usual well-known manner, also being operated by ordinary mechanism Connected therewith.

In the foregoing specification I have described only one reel, crane, and cupola; but, if desired, two of each may be employed, and the other parts made to correspond therewith, as shown in Fig. I, thereby increasing the production of my improved mill.

By the use of two cranes and converters working alternately the receiving-ladle F and continuous mill may be kept in constant operation, as will be readily seen, the rods being directed to first one reel and then the other as fast as delivered from said mill. and subsequently drawn off, with less haste, to the supplementary rolls, as hereinbefore described.-

In practice I propose to use a suitable switch device for directing the rods into first one and then the other of the conductingpipcs H as they leave the continuous train C.

Although I have shown only two reeling devices in this instance, a greater nu mbcr may be used, if desired,without departing from the principle of my invention.

Having described my improvements in rolling-mills, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is-

l. The combination of a continuous train of reducing-rolls with the means for reducing scrap or pig iron to a molten state, for conducting said molten metal to a suitable receiving-ladle and refining the same duringr the transit thereof, for conducting the metal from said receiving-ladle to and between suitable forming-rolls, and for cutting said metal apart preparatory to its being fed into the first set of rolls of the aforesaid continuous train of rolls, substantially as and for the purposes set forth.

2. The combination of the continuous train of rolls C withr the cutters o, forming-rolls k k, receiving-ladle F, means for supporting said ladle, and means for supplying the same with molten metal, for conducting said metal to the rolls k k aforesaid, and for controlling the discharge and temperature thereof, substantially as and for the purposes set forth.

3. The combination of the reeling mechanism, constructed and arranged substantially as described, and the continuous trahi of rolls C with the cutters o, forming-rolls It: k, receiving-ladle F, means for supporting said ladle, and means for supplying the same with molten metal, for conducting said metal to the rolls k It' aforesaid, and for controlling the discharge and temperature thereof, substantially as and for the purposes set forth.

4. The combination of one or more sets of supplementary rolls, the reeling mechanism, constructed and arranged substantially as described, and the continuous train of rolls C with the cutters o, tbrming-rolls k k, receivingladle F, means for supporting the same, and means for supplying it with molten metal, for conducting said metal to the rolls kkaforcsaid, and for controlling the discharge and temperature thereof, substantially as and for the purposes set. forth.
