METAL-ROLLING MACHINE.

SEEGIFICATION forming part of Letters Patent No, 666,057, dated January 15, 1901. Application filed April '7, 1900. Serial No. 12,008. \No model.)

To all whom, at may concern:

Be it known that I, WILLIAM L. J ONES, a citizen of the United States, and a resident of Park View, in the county of Essex and State of New Jersey, have invented a certain new and useful Im provement in Rolling-Machines, of which the following is a specification.

My invention relates to improvements in machines for rolling metal; and the object of the invention is to provide a machine by which a metal slab or billet may be subjected to a rolling effect of such a character as to cause the metal to be reduced in thickness and to be extended in area to substantially corresponding longitudinal and lateral extents. In ordinary metal rolling machines, wherein a slab or billet is passed between two powerful compression-rolls, the metal in being reduced in thickness is principally expanded longitudinally and the lateral expansion is comparatively slight. arts wherein it is desirable to eifect a rolling action of such a character as to secure as great a lateral expansion of the metal as its longitudinal expansion, or substantially'so, in order that there may be 'a minimum waste of metal. facture of ladles the slabs or billets are generally spade-shaped, with a handle of substantially the required thickness and with a flat generally disk-like head of the thickness of the handle and which it is desired to reduce in its vertical dimension and to expand both laterally and longitudinally. In the working of billets of this kind it is the practice at the present time to effect the reduction in thickness of the heads by means of power-ham mers, since no rolling-machine has heretofore been suggested by which this work can be effected by a rolling operation.

I have designed my machine with the special object in view of properly rolling the slabs or billets from which ladles are made; but the machine may, with or without modifications obvious to skilled persons, be employed for the rolling of other slabs or billets and for analogous purposes.

Broadly stated, my invention comprises a table on which the work is placed, said table being preferably arranged in a horizontal plane, a series of compression-disks forming a sectional roll cooperating with the table for There are many Thus, for example, in the manu-' the sectional roll whereby the sectional roll will be caused to engage with all portions of the slab or billet, including that portion coincident with the center of rotation. The relative rotatable movement of the table with respect to the roll is preferably efiected by. rotating the table; but said movement may be efiected by employing a stationary table and by revolving the sectional roll or series of disks rotatably with respect to the same. The former construction, however, enables me to employ simpler driving mechanism than the latter.

Preferably the invention also comprises, in combination with a table and a sectional roll, (the table and roll being movable with respect to each other both rotatably and laterally,) suitable mechanism or means for moving the table and roll toward and away from each other to the proper extent to thereby secure the desired rolling effect upon the slab or billet. Thus when a horizontal turning table is employed in combination with a sectional roll movable laterally with respect to the table the driving mechanism for turning the table may also operate suitable devices for moving the roll toward and away from the operative face of the table to the extent desired. The lateral movement of the table and sectionalroll with respect 'to each other may be effected by any suitable devices, and I shall describe convenient mechanism for this purpose as a specific instance of my invention. The mechanism by which the table and roll are caused to approach each other to secure the desired compression efiect upon the slab or billet is preferably of such a character as to permit of an adjustment of this movement whereby the machine may be employed for working upon slabs or billets of diiferent thicknesses and for reducing them to ditferent thicknesses, and I shall describe herein as a specific instance convenient mechanism for securing this object.

It is desirable in a machine of the type to which my invention relates that provision should be made to permit the separation of the table and roll manually when desired in order to remove the slab or billet for any purposeas, forinstance, in the case of a breakdown in the driving mechanism, which might otherwise not result-in a sufficient separation of the table and roll to allow the withdrawal of the slab or billet. My machine provides for the securing of this object also.

I propose to effect the rolling of slabs or billets when the latter are made work able by heat, and it is therefore desirable that the machine should be provided with means for keeping the table properly cool. My improved rolling-machine in its preferred form contemplates the submersion of the table in a water-bath at all times in order that the temperature of the table may be kept sufficiently low. a

My invention contemplates .various improvements in details of construction in'addition to those which have been briefly referred to and which will be more fully described and claimed herein.

3; Fig. 5, a plan view; Fig. 6, a cross-section showing the preferred construction of the adjustable eccentric for use in effecting the ap proach and recession of the sectional roll, and Fig. 7 a face view of Fig; 6.

In all of the above views corresponding parts are represented by the same numerals of reference.

1 represents a suitable base, to which are secured the two side frames 2 2. ing these side frames is a heavy rigid bed 3,

formed with a vertical bearing 4 therein, as;

Mounted in this hearing is a shaft 5, which carries a table 6 of the desired dimen-' shown.

ing a water-bath, to which water may be ad mitted by a pipe 8 (see Fig. 3) and taken off through an overflow 9. When a water-bath is used, the bearing 4 is provided with a flange 10, (see Fig. 3,) which prevents leakage of water down through the bearing.

The main shaft'll of the machine is mounted in bearings in the frames 2 2 and in'an end; This shaft carries the fast andbearing 12. loosepulleys 13, as is common, and it may also carry a flywheel 14. Motion between the shaft 11 and table-carrying shaft 5m'ay be communicated in any suitable way; butv since the table 6 turns relatively slowly an effective connection is to employ tom; 15'

on the shaft ll, which engages with a wormg'ear16 on the shaft 5.

Mounted above the table is a sectional roll dius of the table.

'of the sleeves 21. I operation, the frame 25 may be suitably braced and strengthened, as shown.

Connect Pref *billet, as will-be obvious. this movement, I form the inner faces of the journal boxes 22 with oppositely disposed 1'7, formed of a series of. disks 18, loosely mounted on a shaft 19. The disks may be arranged in two series, as shown, placed on opposite sides of a disk 20 of smaller diameter, which is keyed to the shaft 19, or the disks may be arranged in a continuous series eX- tending entirely across the face of the table or to any other extent equal at least to the ra- The construction shown is that which I prefer to adopt. The shaft 19 is preferably carried in sleeves 21 and is located eccentrically within said sleeves, as shown particularly in Figs. 3 and 4:. The sleeves 21 are mounted in journal-boxes 22, which are preferably square in cross-section and work in guides 23 (see Fig. 4.) in the side frames 2.

Each of the sleeves 21 is connected to a lever form a handle 26, by which both may be operated to simultaneously partially rotate both To secure rigidity in this In operating upon a Hat disk-like slab or billet placed on the table 6 and turned with respect to the rollit will be obvious that if there were no lateral movement of the roll with respect to the table the portion of the islabor billet coincident with the center of rotatio'n would not-be acted on by the roll, and in'this case a projection would be left onthe slab or billet coincidentwith the fixed disk '20. Moreover,unlessthedisksofthesectional =rollwere very closelyfitted together the turning of such roll along the same path on the slab or billet would result in the forming of a series of corrugations or ridges thereon, v

p In order that these objections may be overcome, I move the which'would be objectionable.

rotatable table and roll laterally with respect to each other, and when a horizontal turning table is employed, as is preferable, the sectional roll itself is moved slowly back and forth across the operative face of the table, whereby the roll willoperate on all'portions of the slab or billet, including the port-ion thereof which is coincident with the fixed disk 20, andthis movement also will tend to prevent the formation of ridges on the slab or In order to effect cams 27 of a pitch necessary to give the desiredthrow, and I- cooperate with said cams two other and oppositely-disposed cams 28, secured rigidly to the shaft 19.

It will be obvious that by giving to the shaft 19 a half-rotation, first in one direction and then the other, the two sets of cams 27 and 28 will cooperate together to give a limited lateral or back-and-forth movement to the shaft 19, carrying the sectional roll with it across the operative face of the table 6. This movement of the shaft 19 first in one direction and then in the other may be eifected by suitable mechanical devices. In the drawings for this purpose I show a shaft 29, mounted in bearings 30, carried by one of the side frames 2 and having a worm-gear 3i, which is engaged and driven by a worm 32 on the main shaft 11. The shaft 29 carries a bevel-pinion 33, which drives a bevel-gear 34, keyed to a short shaft 35, mounted in a single bearing 36 on the base 1. The shaft carries a crank 37, to which is connected a rod 38, having a rack formed near its upper end, which rack engages a gear 39 on the shaft 19. A stirrup 40, swinging from the shaft 19 and having rollers 41, is used to keep the rack on the rod 38 in engagement with the gear 39. The length of the crank 37 and the diameter of the gear 39 are so proportioned that on the upthrow of the crank the shaft 19 will be given substantially a half-turn in one direction, while on the downthrow of the crank the shaft will be returned to its former position.

It is desirable in machines of the type under consideration to effect automatically a movement of the sectional roll toward the table in order that the slab or billet thereon may be reduced to the required thickness and to then withdraw the sectional roll from the table to its former position to permit the rolled slab or billet to be removed and a new one to be replaced on the table. I prefer to effect these movements of the sectional roll by means of connecting-rods 42, which are provided at their upper ends with straps 43 encircling the outer ends of the sleeves 21 and operated at their lower ends from eccentrics 44, mounted on a shaft 45. I illustrate the latter shaft as being operated from a wormgear 46, driven from a worm 47 on the shaft 29. The connecting-rods 42 may be provided with turnbuckles 48, by which their lengths may be adjusted. PreferablyI also-provide means for permitting variations in the throw of the sectional roll tow-aid and away from the rotatable table, whereby the machine may be employed for work on slabs or billets of different thicknesses and for the reduction of slabs or billets to varying extents. To this end each of the eccentrics 44, as shown in Figs. 6 and 7, is made, preferably,in two parts 49 and 50, the former being keyed to the shaft 45, eccentrically mounted therein, and the latter being carried by the tapered body of the part 49,eccentrically thereto. When the parts of the adjustable eccentric occupy the position shown in Fig. 7, it will be obvious that the center of the shaft will be concentric with the outer surface of the part 50, with which engage the straps of the connectingrods 42 Rotation of the shaft 45 will therefore not operate these connecting-rods. By turning the part 50 of each adjustable eccentric on the part 49 thereof it will be obvious that the eccentricity of the outer surface of the part 50 will be gradually increased, whereby it becomes possible to effect any desired throw of the connecting-rods, and hence of the sectional roll, as will be understood. The

then in the other.

two parts of the adjustable eccentric may be locked together in any suitable way-as, for instance, by forming the part 50 with a groove 51, extending around its face and having an enlargement 52 at its bottom, in which may work the heads of bolts 53, which pass through openings in the rim 54 of the part 49.

Assuming the improved rolling-machine to be used for the rolling of a slab or billet from which a ladle is to be made, its operation will be as follows: A slab or billet 55 is first secured,-having a handle 56, which is of the desired thickness and which is rested within a groove 57, formed radially in the table 6, so that the disk-like body of the slab or billet will rest upon the table at approximately its center. The handle 26 is now moved downward, moving the levers 24 and rotating the sleeves 21, so that the shaft 19 will occupy its lowermost position with respect to the journal-boxes 22. Power is applied to the shaft 11, and through the worm 15 and gear 16 the table 6 will be slowly turned. Through the worm 32 and gear 31 the shaft 29 will be rotated to turn the gear 34 throughthe pinion 33,thereby operating the crank 37. The movements of this crank cause the rod 38 to be slowly elevated up and .down, giving to the shaft 19 ahalf-turn firstin one direction. and

By reason of the cooperative engagement of the two cams 27 and 28 at each side the shaft 19 will be moved slowly back and forth with respect to the operative face of the table 6 and of the slab or billet carried thereon. The comparatively siow rotation of the shaft 29 will, through the worm 47 and gear 46, rotate the shaft 45 very much more slowly, and the turning of the latter shaft will operate the eccentrics 44 to depress the journal-boxes 22, thereby bodily lowering the sectional roll and causing it to engage with the slab or billet and to reduce it to the desired vertical thickness. As soon as the sectional roll engages the slab or billet the disks forming the roll will be turned by friction and a rolling action will be imposed upon the slab or billet. If the sectional roll did not move laterally with respect to the table,

it will be obvious that a projection would be the disks forming the sectional roll are not closely fitted together. It is obvious that by making a sectional roll of a series ofdisks it can be thus caused to engage with a rotating slab or billet, the surface of which along any radius travels at correspondingly higher speeds, since the sectionsof the sectional roll are free to turnindependently of each other.

When the eccentrics 4:4c of the shaft 45 have lowered the roll to its full extent, the further movement of said eccentrics returns the roll to its formerposition, whereupon the machine is stopped, the completed slab or billet is removed, and a new one replaced, after which the machine is again started.

If for any cause the machine stops during thetime that a slab or billet is engaged by the sectional roll, the latter may be elevated for the. release of the slab or billet by elevat ing the handle 26,'thereby simultaneously moving the two levers 24; and turning the sleeves 21 21 in the journal-boxes 22 to elevate the shaft 19 within such boxes.

When the work to be acted on is heated, as

is, preferable, the table 6 may be kept suf ficiently cool by allowingwater. to constantly circulate within the water-bath formed within the rim 7' of the bed 3, as will be understood. Havingnow described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows;
