SPECIFICATION forming part of Letter Patent No. 760,858, dated May 24, 1904.
' Application filed July 9, 1901. Serial No. 67,617. (No model.) I
ToalZ whom may concern:
Be it known that I, VICTOR E. EDWARDS,
a citizen of the United States, residing in Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Rolling-Mills, of which the following is a specification, accompanied by drawings forming a part of thesame, in which-- Figure 1 represents a diagrammatic plan view of a rolling-mill embodying my invention.
Fig. 1. scale, of a portion of the repeater by which a rod orbar is conducted from the rolls of the roughing-mill to the, rolls of the finishing mill. Fig. 5 is a section online 5 5, Fig. 4. Fig. 6 is a section on line 66, Fig. 4. Fig. 7 is a section on line 7 7 Fig. 4. Figs. 8, 9, 10, 11, 12, 13 are diagrammatic views showing the movement of the rod around the curved section of the repeater leading from the roughing to the finishing mill. Fig. 14 is a plan view, on a larger scale, of the ends of the repeaters in front of and beneath the rolls of the finishing-mill. Fig. 15' is a longitudinal sectional view of a portion of the repeater,
showing a side elevation of the device for throwing the rod or bar out of the repeater. Fig. 16 is a transverse sectional view of the repeater on line 16 16, Fig. 14. Fig. 17 is a and of the various rod-controlling devices, as'
hereinafter described, and pointed out in the annexed claims. i
Referring to'Fig. 1 of the drawings, 1 1 denote rolls ofa roughing-mill, and 2, 3, 4, 5, 6,
Fig. 2 is a sectional view on line 2 2, Flg. 1. Flg. 3 is a sectional view on line 3 3, Y Fig. 4 1s a plan view, on a larger.
and 7 the successive pairs of rolls of a finish ing-mill, which are located in a depression 8 below the floor of the mill of suflicient depth to bring the passes between the upper and lower rolls 9 and'lO, Fig.2, slightly below the level of the floor 11 11 of the mill in order to bring the passes between the rolls into alinement with the troughs or repeaters by which the rod is conducted successively through the MASSACHU- to the first pair of rolls 2 of the finishing-mill,
and fromthe rolls 2 a repeaterl3 conducts the rod to the rolls 3, and from the rolls 3 the rod is conducted by a repeater 14 to the rolls 4, and from the rolls 4 by a repeater 15 to the rolls 5, and from the rolls 5 by a repeater 16 to the rolls 6, and from the rolls 6 by a repeater 17 to the rolls 7, from which it is delivered'through a trough 18.
The straightsections 19 and 21 are slightly wider at the bottom than at the top of the trough, as shown in Fig. 7, with the outer walls 22 flush with the floor of the mill and the inner walls 23 lower than the outer walls and connected by a floor or platform 24, flush with the inner walls 23. The section 20 is 20 of the repeater, and thereby caused to hug the outer wall 22. 'The outer wall 22 of the curved section is preferably undercut, while the inner wall 23 of the curved section slopes upward from the bottom 25 of the trough to the central platform or floor 24 to enable the loop formedin the curved section to be drawn out of the trough upon the floor 24. At that part of the curved section having the least radius the entire inner wall 23 of the trough slopes from the bottom 25 to the floor or platform 24, with the sloping portion of the wall gradually decreasing in width as it approaches the straight sections 19 and 21. Therod in passing around the repeater 12 assumes the position as shown 7 in the diagrammatical views Figs. 8 to 13, inclusive. As the bar 26 enters the curved section its advancing end 27 strikes against the outer wall of the repeater, thereby producing a bend 28 over the inner wall of the repeater at the point 29, said inner wall at this point acting as a fulcrum. The continued movement-of the bar 26 causes its advancing end to slide around the inner wall into the position shown in Fig. 9, when the resistance offered to the advancing end 27 by the curved outer wall will crowd the rod against the outer wall, as shown in Fig. 10, causing it to hug the outer wall around the curve, as shown in Figs. 11 and 12.
When the advancing end has been engaged by the first pair of rolls 2 in the finishingmill, the loop formed in the curved section of the repeater will be drawn over the sloping inner wall upon the depressed floor 24, caused by the taking up of the red by the rolls 2 in advance of its delivery by the rolls 1, thereby shortening the loop, as shown by the broken lines 30 and-31, Fig. 13. The depressed floor 24 providesa support for the loop, which is restrained between the higher outer walls 22 22 of the repeater.
The straight delivery-section 21 of the repeater 19 is provided with an enlargement or gap 32, preferably provided with beveled sides 33 to enable an attendant to turn the rod to properly present it to the circumferential groove or pass of the rolls 2, to which it is conducted between suitable guides and through a conveyer-trough 34. The bar as it is delivered from the rolls 2 is received in a conveyer-trough 35 and delivered to a semicircular repeater 13, by which it is conducted to the pair of rolls 3. The repeater 13 is provided with an enlarged space 36 to allow the, advancing end to be turned in order to properly present it to the groove or pass of the rolls 3, to which it is conducted between suitable guides in the trough 37. From the rolls 3 the bar is conducted through a conveyortrough 38 and curved repeater 14 to the rolls 4.
The repeater 14 crosses the straight section 21 of the. repeater 12 at a lower level, which brings the bottom of the repeater 14 far enough below the straight section 21 to allow the bar to pass through the repeater 14 beneath a bar contained in the section 21 of the repeater 12. The bar after passing the rolls 4 is conducted through a curved repeater to 5 the rolls 5 and from the rolls 5 through a curved repeater 16 to the rolls 6. The repeater 16, like the repeater 14, crosses the repeater 12 at a lower level, and from the rolls 6 the rod is conducted through the curved rcpeater 17 to the last pair of rolls 7.
The troughs through which the bar is conducted to each of the rolls of the finishingmill and through which it is delivered from the rolls is partially shown on a larger scale in Fig. 14, said figure showing a bar held in the troughs. The trough 34 is provided near its mouth or delivery end with notches 39 in its opposite side walls, adapted to receive the flanged ends 40 of movable wings 41, whose free ends 42 are capable of adjustment toward or away from the bar 43 by means of adjusting-screws 44, held in the side walls of the guide 34 and bearing against the wings 41 to press them toward the bar, and by screws 45, which are held in the wings 41 and carry nuts 46, hearing against the outside of the trough for the purpose of holding the wings 41 against the adjusting-screws 44.
The adjustment of the wings 41 enables bars of different sizes to be brought into proper alinement with guide-plates 47, between which the bar is delivered to the circumferential groove 48 of the rolls. The entrance of the trough 35 is provided with a removable bearing-piece 49, against which the bar 43 held by an adjustable guide-plate 50, arranged to press against the opposite side of the bar and adjusted in a manner similar to the wingpieces 41 by means of the screws 51 and Arranged in a recess or opening in the bottom of the trough 35 is a lifting-plate 53, carried upon the spindle 54, to which is attached a crank-handle 55 in order to rotate the plate 53 and lift the bar 43 out of the trough 35 when the advancing bend of the bar has been caught in the next successive pair of rolls. The purpose of lifting the bar out of the trough is to prevent the short kinking or bending of the bar caused by the delivery of the bar at a faster speed than it is taken up by the next succeeding pair of rolls. As the bar is lifted by the plate 53 its continued movement forms a loop entirely free from the trough 35 and supported upon the table 11 outside of and beyond the repeater 13, and in the same manner the bar as delivered from the rolls 4 and 6 mit the passage of the bar from the repeaters upon the floor 11, each of the plates 56 forming a bridge over its respective repeater by which the loops as they increase or expand in radius are supported as they pass over the 5 from one pair of rolls to the next consecutive panded or increased in size slides over the plates 56 of the'repeater 15, and the looped 1 bar in like manner slidesover the plates 56 of the repeater 17. The floor 11 between the re-.
peaters is flush with both the outer'and inner walls of the repeaters, and as the inner walls of the repeaters are higher than their outer walls each'section of floor between the repeaters is slightlyv inclined, as shown in sectional View in Fig. 2.
