SPECIFICATION forming part of Letters Patent No. 573,185, dated December 15, 1896. Application filed February 29, 1896. Serial No. 581,244. (No modelfl To ctZZ whom it may concern:
Be it known that I, SIGMUND V. HUBER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Feed-Tables for Rolling-Mills, of which improvements the following is a specification.
The invention described herein relates to certain improvements in feed-tables for rolling-mills, and has for its object a construction whereby the article being rolled may be prevented from bending or twisting as it comes from the rolls, may be rotated axially, and returned to the rolls for an edging-pass.
In general terms the invention consists in the construction and combination, substantially as hereinafter more fully described and claimed. 1
In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view of a mill having my improved feed-table. Fig. 2 is a side and Fig. 3 an end elevation of the table. Fig. 4 is a sectional elevation, the plane of section being indicated by the line IV IV, Fig. 1. view showing a modification of the construction of the guiding-apron. Fig. 6 is a detail View of the guide-box. Figs. 7 and 8 are detail sections illustrating certain modifications in the receiving trough or box, showing the same in closed and open positions. Figs. 9 and 10 are similar views of a further modification of the receiving box or trough, and Fig. 11 is a plan view of the construction shown in Figs. 9 and 10. i
In the practice of my invention a bed-plate 1 is arranged on a suitable foundation at right angles to the axes of the rolls of the three-high millA. On this bed-plate is mounted a movable frame consisting of the plate 2 and the I-beams 3, and transverse bars 3, 011 which are secured suitable bearings for the longitudinal driving-shaft 4 and the transverse shafts 5, which are driven through suitable gearing 6 by the shaft 4. The plate 2 is provided on its under side with a series of two or more toothed bars or racks 7, with which a corresponding number of pinions 8 engage, said pinions being keyed on a shaft 9. This shaft is provided at one end with a series of radial arms 10, provided wit-l1 sock- Fig. 5 is a similar ets for the reception of capstan-bars, whereby the shaft may be rotated and the frame adjusted transversely in front of the rolls. A series of angular frames 11 are movably secured upon the transverse bars 3 by means of bolts passing through slots inthe bars 3, as shown in Fig. 3. On the vertical portions of the frame 11 are secured the standards12, having suitable bearings 13 at their upper ends for the shaft 14. A series of hubs 15, each provided with an angular arm 16 and a straight arm 17, are secured to the shaft 14 at suitable intervals. To the angular arms are secured metal strips 18 by means of bolts or rivetspassing through lugs 19 on the por tions of the arms at or approximately at right angles to each other, so that the strips will form two adjacent sides of aguide-box. The third side is formed bya metal strip 20, which is secured to blocks 21, pivot-ally connected to the straight arms 17 of the hubs 15. The pivotal connection of the blocks with the arms 17 permits the metal strip 20 to rest at all times upon the plate 22, forming the bottom of the guidebox, and supported by the vertical portion of the frame 11, as shown in Figs. 3 and 4.
A lever 23, preferably counterbalanced, is secured to the shaft 14 for the purpose of rotating the same, whereby the angular arm 16 is lifted, opening the guide-box or trough, and the strip 20, forming the back wall of the box, is moved along the bottom plate 22 to push the article previously fed into the box off thebottom plate onto the inclined apron 24, which may be formed integral with the bottom plate, as shown in Figs. 3 and 4. The apron is preferably provided along its lower edge with an open-topped receiving-trough 25, into which the article will drop from the apron. The walls of the receiving-trough are notched at intervals, as shown in Fig. 2', to allow the grooved rollers 26 011 the countershafts 5 to project up into the receivingtrough, as shown in Figs. 3 and 4. The counter-shafts are driven by the shaft 4, so that the rollers will feed the article back. into the reducing-mill A.
The passes in the upper and middle rolls of the mill are flats or fiat ovals, and the an ticle being rolled is fed by said rolls into the guide-box, by which it is prevented from bendeither flats flat ov he wh le abl is a ing or twisting. As soon as the article has passed from between the upper and middle rolls the lever 23 is depressed, thereby raisin g the top and one side of the guide-box and causing the other side to move over the bottom plate, as shown by dotted lines in Fig. 3. The movement of one side over the bottom plate forces the article laterally onto the inclined apron, down which it will slide and drop on its edge into the receiving-groove. This groove is made of such a widtlncompared to the thickness of the article, that the latter will be held by the side walls in such position as to properly enter the edging-passes formed in the middle and lower rolls of the mill.
In rolling flats the edging-pass should be rectangular; but when rolling flat ovals the edging-pass is usually diamond shape. v
Ilence'ja feed-roller having a groove suitably shaped, as shown in Figs. 3 and 4, to feed a flat article to the edging-pass, would permit a flat oval to rest at an angle therein, two sets of feed-rollers are preferably employed.
To provide for the adjustment of the guidebox and apron to direct the article into one or the other of these feed-rollers, the angular 5 frames 11, to which the box and apron are secured, are movably mounted on the trans- V 4 toeach other. The slides and box are shifted verse bars 3, as hereinbefore described, and the frames 11 have a slot-ted connection with arms 27 on a shaft 28, mounted longitudinally of the main frame in suitable bearings there- The s a is a s provided th arm 5 h n eke r the eeert n e eer- Stan-bars for rotating the shaft and thereby P p y d u t the bo and apron- Afte h bOX a d apro have bee adjusted in cordance with the article to be rolled, 'i. e.,

The slots in the posts serve as guides for the slides 34:, to which an angle plate or strip 35 is secured, the sides of said strip forming the top and back of the guide-box, the back having one edge resting upon or supported in proximity to the bottom plate 22. The front of the box is formed by a plate or strip 36, hinged to one edge of the top of the box,'and to this plate or strip is rigidly secured one end of one or more arms 37, whereby the strip may be turned to permit of the discharge of the article being rolled from the box. The upper ends of the arms 37 are connected by links 3 to the posts or uprights, so that as the box is moved along the bottom plate the strip 36 will be shifted. The slides 34 are connected by links 39 to an arm 40, keyed to the shaft all, which is mounted in suitable bearings on the brackets 32. The shaft is rotated to shift the slides by a lever 4:2, secured thereon. In Fig. 7 the box is shown in position to receive an ar- 131016 from the rolls, While in Fig. 8 it is shown shifted to slide the article onto the apron.
" Figs. 9, 10, and 11 show a construction of guide-box having the sides and top fastened to the slides 3,4, so as to be stationary relative as described in connection with Figs. 7 and S. In order 170 insure the discharge of the article from the guide-box and its delivery onto the apron, the arms 510 are provided with extensions 43, which are made of such shape and length that when the arms are shifted to move the guide-boxover the apron the ends of the extension will pass through slots 44 in the top of the box and push the article out onto the apr n, as sh wn n We It is characteristic of my improvement that provision is made for receiving the article from the rolls at one level and preventing any twisting or distortion thereof, transferring it to a different level and automatically turning the article axially and then delivering it to the rolls in its turned position.
I claim herein as my invention-- 1, In a feedstable for rollingemills, the combination of a plate for receiving an article from the rolls,two or more series of positivelydriven rollers for feeding the article to the rolls, an adjustable apron for directing the article from the plate to either series of feedrollers and means for pushing the article lat.- erally from the plate to the apron, substantially as set forth.
