MACHINE FOR ROLLING EYE-BARS.
SPECIFICATION forming part of Letters Patent No. 349319, dated September 21, 1886.
Application filed April 7, 1886. Serial No. 198,089. (No model.)
States, have invented or discovered certain new and useful Improvementsin Machines for Rolling Eye-Bars, of which improvements the following is a specification.
In the accompanying drawings, which make part of this specification, Figurel is a viewin front elevation of my improved mill for rolling eye-bars. Fig. 2 is a plan view of the rotating bed. Fig. 3 is a view in front elevation, on an enlarged scale, of a portion of the mill, certain parts being shown in section. Fig. 4 is a vertical sectional view on the line a: at, Fig.3. Fig. 5 is a horizontal section on the line y y, Fig. 3. Fig. 6 is a detail view of a modification of the edging device.
The invention herein relates to certain improvements in mills for rolling eye-bars, and
I has for its object such a construction and arrangement of parts as will effect a reduction and elongation of the body portion of a billet, and also the reduction and spreading of the end portions thereof for the purpose of form ing a suitably-shaped head 5 and it is a further object of said invention to so shape the ends of the billets that the longitudinal back and forth passes of the billet between the rolls will produce the desired enlargements on the ends of the bars.
In general terms the invention consists in the constructionand combination of parts, substantially as hereinafter described and claimed.
In suitable housings, 1, are mounted the rolls 2, having operative faces somewhat wider than the heads of the bars to be rolled. These rolls are driven by the usual or. any suitable form of driving mechanism, as shown at A, in Fig. 1, and the upper roll is provided with the usual screw-adjusting mechanism, B. On the ends of the rolls, projecting beyond thehousings, are formed the collars 3, having curved operative faces, as shown in Fig. 1. Between the housings 1 on each side of the rolls are secured the horizontal bars 4, on which are supported the inner ends of the feed-tables 5, having their upper surfaces tangential to the periphery of the lower roll, as shown in Fig. 4,
On the inner sides of the housings and on each-side of the rolls are bolted the brackets 8 and 9, between which are mounted the boxlike frames 10, provided on their outer sides with a rack, 11, arranged to intermesh with the pinions 12, keyed to the shaft 13, mounted in suitable bearings bolted to the sides of the housings, andprovided with an operating hand-wheel, 14, whereby the frames 10 may be reciprocated simultaneously. The ends of the frames 10 are connected and braced by the bars 15, said bars passing under the tables 5, as shown in Fig. 4. About midway of the frame 10 is formed therein a box, 16, for the reception of a journal-box, 1 7, in which is mounted the axle of the vertical roll or disk 18, said roll being arranged to operate in ahorizontal plane passing between the rolls 2, as shown in Fig. 3. These j ournal-boxes are adjustable toward or away from each other by means of liners 19. At one side of the housings, and in planes parallel with the axes of the rolls-2, are arranged suitable guideways, 20, on which is placed a movable bed, 21, constructed to move back and forth on the ways, and having attached thereto a threaded rod, 22, said rod passing through a rotating nut, 23, mounted in a suitable journal formed on the post 24 at the end of the'ways 20, and provided with an' operating hand-wheel, 25, whereby the nut 23 may be rotated and the bed 21 moved back and forth along the ways. On this bed 21 is placed a horizontal platform, 26, having a central pivot-pin fitting within a suitable opening in the loed. The platform is provided with two movable jaws, 27, actuated toward and from each other by the right and left hand threaded rod 28. (See Fig. 2.)
In rolling eye-bars a billet of approximatelythe width desired in the finished bar is heated to the desired rolling heat, the bed 21 having been adjusted at such a distance from the hous-. ings that the end of the billet will, in the rotation of the platform 26, pass between collars 3 of the rolls 2. The bar is then clamped upon the platform. The platform is then rotated in order to feed one end of the billet between the collars 3. Theimpetusiimparted to the billet and platform by the action of the collars will generally be sufficient to bring the opposite end of the billet around into engagement with the collars. This operationis continued, the rolls being adjusted toward each other after the rolling of each end until the portion of the billet acted on by the collars is reduced to or approximately to one-half the thickness of the completed bar. By the action of the collars a transverse groove is formed in the billet at each of its ends, as shown at ain Fig. 1, and at the same time lateral wings or enlargements I) are formed in line or approximately so with the groove (0. (See Fig. 2.) The billet is then removed from the platform 26, and the frames 10, with the vertical rolls 18, having been removed to the position shown in Fig. 5, the billet is placed on one of the tables 5, with the wings I) at one end of the billet on one side of the vertical rolls, and the wings at the opposite end on the other side of said rolls, the body of the billet lying between them. The frames 10 are now moved forward by means of the hand-wheel 14 and intermediate connections, and as the vertical rolls 18 encounter the wings I) of the billet they move the latter forward until it is caught by the rolls 2. The vertical rolls are moved along by the hand-wheel until their axes are in or approximately in the same vertical plane as the axes of the horizontal rolls, and are held in that position by the operator through the medium of the hand-wheel 14 until the wings b on the opposite end of the billet strike against said rolls, and carry said rolls and the frames 10 to the opposite side of the rolls 2, the operator releasing the hand-wheel simultaneously with the engagement of the wings I) with the rolls 18. As soon as the billet has passed between the rolls 2 in one direction, as above described, the operator reverses the hand-wheel, thereby reversing the movement of the frame 1.0 and rolls 18, and again feeds the billet to the rolls 2, which have also been reversed. The rolls 18 are again stopped when between the rolls 2, as above stated, until' moved away therefrom by engagement with the wings I) on the end of the billet. This operation is continued until the desired reduction and elongation of the billet is effected. The rolls 18 serve to prevent any lateral enlargement of the billet during the rolling operation, and also to feed the billet to-the horizontal rolls, as above described, and to square the edges on the finished bar. During 'this longitudinal rolling operation, above described, the body of the bar is elongated and reduced in thickness, and the wings I) are broadened or spread out in lines parallel with the length of the bar.
The notehing or grooving operation first described effects such a distribution of the metal at the ends of the bar that the subsequent rolling operation will produce an approximately cireular head on the bar, as shown in Fig. 5.
In operating the above-described mill, the two rolling operations are carried on simultaneously or separately, as desired.
The roll 18 is made of a width not greater than the thickness of the completed bar, and in lieu of rotary edging disk or roll 18, a stationary disk (see Fig. 6) may be employed to perform the gripping or edging functions, as will be clearly understood.
The bed 2]., after being once adjusted for a certain length of billet, is kept stationary until billets of a different length are to be rolled, and the table or platform may be made movable transversely of the axes of the rolls,2.
I claim herein as my invention 1. In a mill for rolling eye-bars, the combination of a pair of horizontal rolls and a pair of vertical rolls, having, in addlti'on to a rotary motion, a motion in the general direction of the feed to or toward, as well as away from, the point of bite of the horizontal rolls, sub stantially as set forth.
2. In a mill for rolling eyebars, the combination of a pair of horizontal rolls, and a single mechanism for feeding the article to be rolled to the horizontal rolls, the same mechanism being alternatively operative on both sides of the horizontal rolls, substantially as set forth.
3. In a mill for rolling eye-bars, the combination of a pair of horizontal rolls having operative faces between the housings, the ends of said rolls projecting beyond one of the housings,said proj ccting ends provided with grooving-collars and a movable table or support for feeding the ends of the article to be rolled to said grooving-collars, thereby so shaping the I ends of a billet that the subsequent action of the rolls will produce the desired enlargements on the ends of the bars, substantially as set forth.
4'. In a mill for rolling eye-bars, the combination of a pair of horizontal rolls having operative faces between the housings, the ends of said rolls projecting beyond one of the housings and provided with grooving-collars, and a rotating table for feeding the ends of the billet to said grooving-collars, whereby the ends of the billets are suitably shaped with reference to the formation of enlargements on the bars by the action of the rolls, substantially as set forth.
5. In a mill for rolling eye-bars, the combination of a pair of horizontal rolls, guides lobox, 16, and an edging-disk mounted in said 10 box, substantially as set forth.
In testimony whereof I have hereunto set my hand.
HENRY AIKEN.
