Specification of Letters Patent Patented Sept,- 10, 1912, Application filed October 6, 1909.
Serial no. 521,416.
To all whom it may concern I Be it known that I, DAVID F. Nisenr, citizen of the'United States,'residing at Crafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rolling'Mill 'Appliances; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others. skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in the type of rolling mill appliances usually known as manipulators, the purpose of which is to arrange an ingot, slab, billet or bar in proper position on the feed tables to enter the desired pass.
The object of my invention is, not only to provide a means for the alinement of the ingot, slab, billet or bar in its proper position in front of the pass, but to turn the ingot, slab or billet so as to present fresh surfaces to the action of the rolls, and more particularly to upturn on edge comparatively wide and thin slabs and hold them in position for edging on either or both sides of the mill.
Another object of my invention is to pro" vide an appliance for rolling mills whereby the ingot, slab or billet, after having passed through the rolls, can be held in position for a return pass through the same groove, or be shifted to other grooves, independently of the mechanism on the leading side of the mill, and which also, when necessary, can be operated so as to move the side guards on the following or catchers side of the mill, so that they will, approximately register with the side guards on the leading or rollers side of the mill, so that in the case of a wide slab on edge, the slab, after passing through the rolls from the leading side of the mill will enter between the side guards on following side, and be maintained in its edgewise position for the return pass.
I am aware that mechanism has been devised for operating the side guardsof mill tables for accomplishing this latter purpose, but these are so devised and constructed as to move all the side guards simultaneously, which is not only unnecessary when rolling some classes of material, but also consumes power uselessly and .entails unnecessary wear. 7
A further object is to provide a manipulator that is' simple and efficient, and in In the accompanying drawings, Figure 1 v is the plan view of a portion of the rolling L mill and tables to which my invention is applicable. of the tables and manipulator on line a a? of Fig. 1; Fig. 3 is a transverse section of the table on line b b of Fig. 1, and a side elevation of the moving side guards; Fig. 4 shows my manipulator in the two extreme lifting and pushing positions; Fig. 5 is a modification of the manipulator, showing a different method of compelling the manipulator head to travel parallel to the rolls.
1 represents the roll mounted in the housings, 2 2; 3 3, etc., represent the rollers in the feed-tables on one side of the mill and 4 4-, etc., the "rollers in the opposite feed table. Above the feed-table rollers 3, there is shown the movable side guard 5, which is attached to the beams 6 6, which are slidably mounted in the oscillating guides 7 7 Fig. 2 is a transverse section The oscillating guides 7 7 are pivotally mounted in the bearings 8 8, and are sub ject' to constrained movement in a vertical plane, by means, in this case, of the hy draulic cylinders 16 16; any other motive force, however, may be substituted.
9 is an operating shaft which has an oscillating'movement controlled by the motive cylinders 14 and 15 through the links 13 and lever arms 12. On the ends of the shaft 9, there are lever .arms 10; 11 11 are conmeeting rods, which connect the levers 10 17 is a cam also the levers 25 and 27, and is operated through the links 4 1 4 1 by the motive cylinders 28 and 29 or. other power. To the upper ends of levers 25 and 27 are attached connectingrdds'z-BO 30 for actuating the side guard ,"Theside guards 31, 32 and-33 have only'a horizontal travel, and the construction and operating mechanism is similar, except as stated hereafter. 34 is ashaft operated by'the cylinders 37 and 38, or other actuating medium, and through mechanism as heretofore described Operates the side guard '33. This shaft extends to the opposite side of the mill where a similar mechanism is located for operat ing the side guard 32, by means of the cylinder 39 and 40.
'35 is a lever arm attached to 34 and at its end is provided with a lug .or roje'ction 42 extended toward the lever 36 w ich also has a projection 43 extending toward the lever arm 35, the lugs or projections so arranged as to interfere and act as stops when in certain positions.
The operation of 'my invention is as follows: For convenience of description, I have designated the entire mechanism of the manipulator A and the moving side guard mechanism on the opposite side of the table B, and the apparatus on the opposite side of the mill C and D. The side guard 5, it
will be noted, has at-its lower side, exten' sion. 5 extending downward between the rollers 3 3, these extensions having a curved like projection 5.
contour, the upper terminus of whichis in front of the side guard and forms the shelf- When it is desired to turn an ingot, slab or billet, the side guard 5 is moved bythe cylinder 14 over to the piece to be turned, when the shelf- 5 is be;
ne ath the piece, the cylinders 16 are brought into action, lifting the side guard 5, shelf 5 and carrying with it the piece to be turned, following up horizontally by means of the cylinder 14, and placing the piece in position for rolling by means of mechanism A and B. I
'The functions of the cam 17 and friction roller 18 are to cause the moving head 5 to travel across the table parallel to the rollers, when the head is in an elevated position. A modified form of my invention, embodying the same principle, is shown in Fig. 5, the function of the cam being performed in this case by the stationary guide 46, which limits the vertical travel of the roller 45, and consequently the oscillation of the guide 7, the movement of the .head 5 being the same as in the preferred form of appliance hereinbefore described. I
whereby the moving guards-of C'and D can be used only when necessary, and when 'mentwith it.
in unison with the shaft 9. On the shaft 19 at the end near mechanism C is the lever 23, to which is attached a slotted stop link 21, which encompasses a pin 24 on the lever 25 of mechanism C. The length of the slot in the link 21 is equal to the travel of the lever arm 23 at the point of connection to the stop link 21. Therefore, when the moving guide 5 is stopped at any predetermined position, the moving guard 31 of mechanism C will remain at rest, but if it is desired to bring 31 in substantial alinement with 5, Water is admitted into the cylinder 28 of mechanism C, which will force the guard 31 to move over until the pin 24 comes in contact with the end of the slotted stop link 21, and there will stop because the cylinder 15 of mechanism A is of practically the same area as cylinder 28 of mechanism 0. .Inpractice, I put cylinders 15 and 29 on a constant pressure line and make 14 large enough to overcome 15, and 28 large enough to overcome 29. The operation of mechanism B andfD is as follows: The shaft 34 extends to a point near to the end of the operating shaft 41 of mechanism D, and is in substantial aline- On the adjacent ends of the shafts 34 and 41 are the lever arms 35 and 36, having interlocking lugs or projections 42 and 43, the lug 42 being in front or toward the mill with reference to 43. lVhen the guard 33 of mechanism B is stopped at any given point, the shaft 34 carries the arm 35 and lug 42 with it and it is evident that if the guard-32 of mechanism D is moved over, it can only move to a point Where the lug 43 will make contact with the lug 42, and there sto since, as in the case of mechanisms A an C the pressures in the cylinders 37 and 40 oppose each other and form an equilibrium.
. Although the description of the mechanism and operation has been confined largely to that of a manipulator for blooming mills, I do not intend to limit its application to this practice, as for instance I can use it in whole or part on bar mills, and by slmrtcning the downwardly project-ing lugs on the moving guard 5 and changing the shape, I can not only push a bar or billet over a table, but can reach over it and pull it back. Changes within the scope of the appended claims may be made in the details of con Having described my invention, 1 claim:
