GUIDE FOR ROLLING MILLS Filed March -26, 1928 2 Sheets-Sheet 2 ing surface has only a relatively short forward projection from the reducing pass, instead of extending, as usual, for the full length of the guide. This construction per mits a roller 10 to be incorporated within the length of the guide, said roller having its axis at right angles to the direction of travel of the stock in the guide. Said roller 10 is so journalled either in the guide itself, or independently thereof as shown, as to contact on its periphery with said stock, thereby to move it longitudinally, due to rotation of said.

roller 10 in the same direction as conveyor rollers 2, 2, through the medium of gearing 11 from the shaft 6. In this way, without any sacrifice of accuracy in guiding, pieces of stock so short that they would become stuck in any ordinary delivery guide, are readily handled in and promptly discharged from the guide, by the forward motion imparted to said pieces by the driven roller 10. In addition, the incorporation of this roller 10 in the guide lessens the danger of a piece jamming therein, as sometimes happens when the adjustment of the guide, to the line of the pass or to the section of the stock, is faulty. And if a cobble does occur, the guide can be freed much more readily than an ordinary guide because of the better access afl'orded to its interior from its outer end.

As shown in Fig. 3, the presence of the roller 10 prevents the hot billet or bloom from bending down, notwithstanding the absence of support therefor which results from the the omission to extend outwardly the lower section 8 of the guide. The same is true of the modified form of roller designated at 12 in Fig. 4, and having a peripheral groove 13 to receive the lower corner of the billet or bloom, thereby to eliminate the possibility of any twisting. In both forms, the cooperation existing between the driven roller, incorporated in the guide, and the stationary guide sections 7 and 8 serves to confine the billet or bloom laterally in every direction while at the same time leaving it free to be moved longitudinally by said roller, as soon as released by the reducing rolls. In other words, the use of such a roller makes it possible to employ a guide that is long enough to hold the billet straight, and that still does not have to fit the billet with undue closeness.

With the driven gu ide roller supported, as shown, independently of the other members of the guide structure, the vertical adjustment of the lower roll of the stand of rolls 1, 1, by any suitable adjusting means 1 1, maintains the correct alinement between the reducing pass and the surface of said driven guide roller. However, my invention is not limited to such independent support of the driven guide roller, but what I claim and desire to secure by Letters Patent of the United States is as follows 1. The combination with a stand of reducing rolls of a rolling mill and a delivery guide adjacent the discharge side of the pass between said rolls, to engage with and maintain the direction of the rolled product as it emerges from said pass, said guide having incorporated therewith, in close proximity to said pass, a driven roller to procure the discharge of the rolled product from said guide, after said reducing rolls are no longer effective to impart movement to the last end of said product.

2. In a delivery guide for rolling mills, a relatively elongated portion providing interior guide surfaces to engage and maintain the direction of the rolled product as it emerges from the reducing pass between a pair of rolls, a shorter portion opposing said elongated portion, and a driven roller supplementing said shorter portion and adapted, by engagement with said rolled product, to insure the latters discharge from said guide, following the emergence of the last end of said rolled product from the reducing pass.

3. In a delivery guide for rolling mills, a

pair of rolls, a shorter portion opposing said" elongated portion, and a driven roller supplementing said shorter portion and adapted, by engagement with said rolled product, to insure the latters discharge from said guide, following the emergence of the last end of said rolled product from the reducing pass, the axis of saidroller being at right angles to the line of movement of the stock through said guide, and said roller cooperating with said guide portions to maintain the rolled product in its line of delivery, in the absence of any twisting or lateral deflection.

4:. The combination with a stand of reducing rolls, of a delivery guide therefor having incorporated therein a driven roller to engage and forward the rolled product after the last end of the latter has cleared said rolls, and means for vertically adjusting the lower roll of said stand, to maintain alinement between the reducing pass and said driven guide roller.

5. The combination with a stand of reducing rolls, of a series of conveyor rollers to receive the rolled product from said reducing rolls, and a delivery guide interposed between said reducing rolls and said conveyor rolls, said delivery guide having incorporated therein a driven roller to engage and forward the last end of the rolled product, when the latter has cleared said reducing rolls.

6. The combination with a stand of reducing rolls, of a series of conveyor rollers to receive the rolled product from said reducing rolls, a delivery guide interposed between said reducing rolls and said conveyor rolls,

said delivery guide having incorporated therein a roller to engage and forward the last end of the rolled product, when the latter has cleared the reducing rolls, and common driving means for said conveyor rolls and said guide roller.

Dated this 13th day of March, 1928.
