WIRE-ROLLING MILL.

SPECIFICATION formingpart of Letters Patent No. 560,108, dated June 20, 1893.

Application filed January 17, 1891. Renewed June 14, 1892. Serial No. 436,661. (No model.)

To all whom it may concern:

Be it known that I, HENRY ALEXIS WIL- LIAMS, a citizen of the United States, and a resident of Taunton, in the county of Bristol, State useful Improvement in Wire-Rolling Mills, of which the following is a specification.

My invention relates to so-called continuous train rolling mills in which the rolls are arranged alternately in oppositely inclined planes for being placed at right angles to each other successively, and is designed more especially for facilitating the reduction of wire rods to small wires in the cold rolling process, but is applicable also in various respects for roughing or breaking down rolls such as are employed for reducing blooms or billets to wire rods as hereinafter fully described, reference being made to the accompanying drawings in which- Figure l is a fronttelevation of my improved wire rolling mill with some parts in section. Fig. 2 is a plan view of a portion of the mill including two pairs of rolls and the gearing for applying the driving power, with some parts in horizontal section. Fig. 3 is a looking in the direction of the axis of the rolls of one pair. Fig. 4 is a plan view of a guide for conducting the rods or wires from one pair to another of the rolls. Fig. 5 is an end elevation of said guide. Fig. dis a plan view of the upper part of the guide inverted. Fig. 7 is an end elevation of said part represented in Fig. 6. Fig. E} is a plan view of the lower part of the guide with a reducing guide at the delivery end, half of which is shown detached and inverted. Fig. 9 is an end elevation of the part represented in Fig. 8. Fign 10 is a plan view of part of the reducing guide modified so as to extend into the angle between the rolls. Fig. ll is a front elevation, and Fig. 12 a side elevation of a modified form of the rod-gaging attachment. Fig. 13 is an end elevation, Fig. 14. a side elevation, and Fig. 15 a plan view of a modified form of guide to be used between the respective pairs of rolls. Fig. 16 is a longitudinal section of one of the roll shafts and transverse section of the rollhousingsshowing the means of adjusting the rolls lengthwise for alignment of the passes. Fig. 17 is a front elevation of housings and toothed wheels coupling a pair of rolls showing a modified arrangement of adjusting devices for the rolls. Fig. 18 is a front elevation of an adjusting key employed in the arrangement of Fig. 17.

On the bed plate or fgame a, which is to be of sufficient length for the entire train of rolls of which there may be twelve to fifteen pairs or sets more or less, I place at intervals corresponding to the distance apart which it is desired to have the pairs of rolls, the transverse triangular base supports b, for the individual pairs or sets of rolls, the sides of which are at right angles to each other and forty five degrees to the horizontal plane, and one side of each is extended at 0, above the apex of the two. sides a suitable length for supporting the roll housings on the upper side of the incline so as to be geared at the lower side with the driving shaft said base supports being placed with their extending sides 0, in the opposite inclinations alternately. These base supports may be cast together with the bed plate a, if desired, but for convenience of handling it will probably be preferred to make them separately and bolt them to said bed plate.

On the upper part c, of each base support is a pair of grooved reducing rolls d, mounted in housings e,]", of which the partf, is preferably made integral with the bench g, the other e, being detachably fastened to said bench for facilitating the application and removal of the rolls. The gear housing 72., is also supported on this bench and is also preferably made integral with it. The bench is used to support the housings at a suitable height above the supporting base a, to afford space between the housings and the said supporting base for the intermediate shaft 2', and its upper bearing j, said shaft being geared with the lower roll shaft 7c, by the spur wheel Z on the latter and the pinion m, on shaft 2', and itself being geared by the bevel wheels 91., with the line-shaft 0, at one side of the base, two such shafts being employed one on each side for gearing with the rolls of the different inclines, and both being geared with the main driving shaft 19, through the pinion g on said driving shaft and the spur wheels 3, on the said line shafts. The roll housings are thus mounted on the intermediate bench, and the intermediate shaft is used to gear the rolls with the line shafts to facilitate the application of the step bearing and the water circulating connection, and also the friction device. all in connection with the lower roll shaft described farther on, which couldnot well, be employed if the said shaftwere geared directly with the line shaft. The lower roll shaft 7c, has its lower end bearing in the 'standard t, resting on one of the sides of the triangular base supports 1), and below the apex of the same, said shaft having'the pinion 23 fast on or made integral with it andbeing continuous through the lower roll'and hav-f ing its upper bearing in the removablerollf housing c, with the adjustable end thrust orf step bearing to, for the lower end, in the bored) hole of the standardand confined by the cap *0, screwed on the neck w, of theistan'dard for a means of adjusting the step as the shaft is; shifted lengthwise from time to time foralignment of the pass grooves with. packing rings? at w and y, adapted form'aking water tight joints between the end of the rotating shaft and the stepbearing u,said bearingand die:

The upper roll'shaft is also continuous and has its pin- "ion23 fast on it, same as the'lower one, and is bored for the circulation of waterwh'ich enters the upper end throughipipe 11, and escapes from the lower end through the thrust bearing elbow 9.

The rolls d, are deta'chalolyfitted to the shafts for removal to renew thelpass groovesandto reverse them'for alignment of each of the two pass grooves with the guide. They are "fitted able collar 16, and the nut 16 whichclutchesj the roll fast and "being removed allows the roll to be changed.

For adjusting the rolls Ipropose to utilizef the upper-"and lower journal boxes 17, in the? housin gs f'and h,whieh I-arrange so that they; can shift lengthwise alongthe shaftto'a liin-i it'ed extentwith means for forcing the outer; endsa'ga'inst the pinions 23;which may consist' of the cone pointed thrust studs 18 placed in suitable chambers in the-:housings with their heads behind the'side flanges wet the", bearings overlapping the housings, with the cone pointed adjusting screws-20, screwing in through the sides of the housings against; said points of thestuds so as to thrust them against the flanges of the boxes and-cause them to shift the clutch collars and the rolls,

owing to the-close proximity to the boxes,

where it would be difficult to work the set screws.

- Thespur wheel l,bywhich the lower roll jshaft7c,-is-driven,is madefast to the shaft by a friction device consistingof the friction collar 24andcone 25, the co'nesocket 26 in the hub of the wheelgand the adjusting nuts '27 screwed onthe shaft to adjust the cone, the object "of which is toallow thewheelto shift and avoid stretching the rod or wire too much whenit may happen thatthe elongation of the rod or wire is not equal to the increased speed of the rolls towhieh therod or wire is moving, over' the speed of the rolls from whi'ch itisissuing, With s'u'cha f'ric-' tion clutch to-each pair of rolls except the first it is designed to speed therolls a little faster than the speed of the rods or wires so thatthey will always bet-aut'between the rolls and will run through straight tubular guides from'one pair of rolls to another, but -as-it willsometimeshappen that the rods or wires will getstalled in the guides so that ing the "hingejoint lugs3l, and the other has the forked lugs'32 for hinging themto'gether, and both have forked lugs as33 by'which to fasten-them with the bolts '34=hinged in the IOO S ready access for clearing out the obstruction llO forks of the part 28and'adapte'd to'swin'g into theforks of part 29 ,,"to be clamped" fast with "said bolts 34,whenfclosed in a mannei' adapt ed forreadily fastening and -'unfastening thein.

passes.

10' to extend into the angle between the rolls close to where the rods or wires enter the With such reducing guides of diflerent sizes the guide ways may have the bore large enough for the largest sizes, and be adapted for all sizes. I

Instead of the arms for fastening the guide to the housings it may have the standard 30, as in Figs. 13 and 14 mounted on a shaft 30 that may be extended along the train of rolls in suitable bearings under the benches or formed together with them.

It vwill be seen that whenever any obstruction occurs in the guide way it may be quickly and easily unfastened for opening by slacking the nuts 24 and swinging down the bolts.

The chief difficulty in the way of uniformity of reduction and elongation of the rods or wires, and the consequent variations in the tension and occasional overrunning and clogging of the wires in the guides is mainly due to the variations in the sizes of the rods as they come from the rod mill, but to some extent also to the different qualities and conditions of the metal which I have found can be greatly relieved by the employment of one or more pairs of gagin or sizing rolls in advance of the drawing rolls, by which I mean rolls that are not geared and through which the rods are pulled by the reducing rolls behind them, and I have therefore represented in this case a pair of such rolls at 39 and 40 immediately in front of the first pair of rolls d, said rolls being in this case mounted in a housing frame 41, seated on the projecting edge 42 of the bench g, the upper roll 40 being fitted in a frame 42 which is suspended by pivots 43 from the boxes 44 fitted in the vertical slide ways 45 in the upper part of the housing with the adjusting screws 46 to set said boxes, and the said upper roll, with springs 47 under the boxes to hold them up to the screws. The purpose of this swinging device is to allow of opening the rolls to enter the rods to begin with without changing the adjusting screws, as must be done when the screws are the only means of openingthem, and which is very obj ectionable because of the difficulty of restoring them to the exact gage as before with the screws, while in this arrangement the gage having once been fixed by the screws the roll returns to exactly the same position and the gage remains the same. In this case the rods are inserted through the open gaging rolls into the first pair of reducing rolls so as to be gripped sufficiently to be drawn forward after the gaging rolls are closed. Ihave in this example only represented one pair of gaging rolls but it is obvious that twoor more pairs may be employed if desired, in which case they will be placed in the same line and also at right angles to each other like the reduc- I have represented the upper sizing or gaging roll as the one adapted for swinging open, but it is obvious that it may be the lower one if preferred. a

It is not necessary to have the roll swing for opening and I do not limit myself to that arrangement because it may slide back and forth as well, as I have represented it in Figs. 11 and 12 where the'eeeentric rolls 48 are interposed between the adjusting screws 46 and boxes 44, suitably for being "shifted by lifting the handle 49 so that the spring 47 may lift the roll to the desired extent for opening them, and the fall of the handle will shift said eccentric rolls and close the sizing rolls. It is ob vious that other means of opening and closing said sizing rolls may be employed.
