ROLLING-MILL.

Patented Nov. 5, 1918.

Application filed September 24, 1917. Serial No. 192,864.

.1 0 (M whom it may concern:

Be it known that I, JEROME R. GEORGE, a citizen of the United States, residing at lVorcester, in the county of Worcester and Commonwealth oflllassachusetts, have invented certain new and useful Improvements in lilolling-ltlills, of which the following,taken in connection with theaccompanying drawings, is a specification, the present application being a continuation in part of my previous application, Serial No. 868,912, filed October 27, 1914:.

Among the objects of my invention is to increase the capacity of rolling mills, particularly merchant mills, and to enable the product of such a mill to be varied in size and dimension, the treatment of said product being continuous, as in the usual form of mill, from the heating furnace to the cooling bed on which the product is finally received.

The above and other objects are accomplished by the novel disposition and arrangement of the various stands and trains of rolls in a rolling mill. as hereinafter described, reference being had to the accompanying drawings in which Figure 1 is a diagrammatic plan view of an arrangement of apparatus which is suitable for the carrying out of my invention.

Fig. 2 is a similar view of the same apparatus in a slightly modified arrangen'ient. Like reference characters refer to like parts in the different figures.

Referring particularly to Fig. 1, I have indicated at 1 a portion of a heating furnace, from which the metal is delivered, for coi'itinnons reduction, to a train of rolls 2, by any suitable delivery means. The train of rolls hereinafter referred to as a roughing train, may consist of any number of stands of rolls for the continuous and progressive initial reduction of the metal emerging from the furnace 1, said train being herein illustrated as consisting of four stands of rolls which are driven by suitable gearing from an independent prime mover, such as a motor 3. ln the line of delivery of the metal from the roughing train 2 is prefer ably disposed one or more stands of feed rolls 1. 4, here shown as two in number, and driven through suitable gearing from an independent prime mover, such as a motor 5. The stands of rolls serve for the delivery of the heated product, as reduced in section by the roughing train 2, to a suitable guide 6 the metal from the roughing train 2 and feed rolls 4, 4.

In common with other mills the present I Fig. 1, such a finishing'train may consist of one ormore stands of rolls 7 and 8, and

in the present instance, for convenience of illustration, only one each of such stands is shown. The rolls of the stand or stands 7 are capable of rotation by suitable gearing from an independent prime mover, such as a motor 9, to move the metal in a direction opposite to its passage through the guide 6, which latter may have a suitable curved branch or guide 10 for delivering the metal to the rolls of stand or stands 7. The stand or stands 8 which form part of this finishing train are adapted to. receive the metal in a loop 11 from the stand or stands 7, and are driven by suitable gearing from an independent prime mover, such as a motor 12. The above finishing train elements areduplicated on the opposite side of the line of delivery of the metal in guide 6. by the initial stand or standsli-S, driven by an independent motor 14, and receiving the metal through a curved branch or guidelfi, and bv a final stand or stands 16, receiving the metal by a loop 17 and driven from a suitable motor 18. I

In the operation of the apparatus thus far described, a variety of modes of treat ment for the heated metal may be availed of, by reason of the particular arrangement and disposition of the stands constituting the final or finishing trains on opposite sides of the line of delivery of the metal. For instance, if desired, the guideti may be employed to conduct the metal directly to the cooling bed, in its original line of delivery from the roughing train 2 and the stands of feed rolls 4, in which case said stands 4 will serve as the final or finishing rolls of the mill. As herein shown, the guide (3 termiwhich is arranged in the line of delivery of scribed may be run'to gether infseries, jwitl1 'line of deliver and all adapted to run,

selectively, in t e same or the opposite direction'to the roughing and feeding rolls, and also to the intimate direction of the metal in the train. Such an arrangement is susceptible of numerous immaterial variations from the forms )roposed herein, especially in the manner oi conducting the metal toward and from the finishing rolls, wherein the greatest latitude may obviously be availed of, without departing from the spirit and scope of my invention, as expressed in the appended claims.

I claim, 1

1. In a rolling mill, the combination with feed rolls for supplying metal to the rolls of a finishing train, of a finishing train comprising rolls running in the opposite direction to said feed rolls and spaced from the line of delivery from said feed rolls, and

delivery rolls adapted to runin the same direction as said feed rolls and located nearer to their line of delivery than the first mentioned rolls of said finishing train.

2. In a rolling mill, the combination with feed rolls for supplying metal to a finishing train, of a finishing train comprising rolls running in the opposite direction to said feed rolls and spaced from the line of delivery of said feed rolls, and deliverfrolls adapted to run in the same direction as said feed rolls, said finishing rolls being in staggered relation to each other, win the delivery rolls nearer to the line of delivery of said feed rolls.

3. In a rolling mill. the combination with feed rolls for supplying metal to a finishing train. of a finishing train comprising stands of rolls on each side of the line of delivery from said feed rolls but spaced therefrom, each of said stands running in opposite directions to said feed rolls. and stands of rolls on each side of the line of delivery of said feed rolls and nearer thereto than the first mentioned finishing stands.

4. In a rolling mill. the combination with food rolls for supplying metal to a finishing train, of a finishing train comprising stands of rolls on each side of the line of delivery from said feed rolls but spaced therefrom,

each of said stands running in opposite directions to said feed rolls; and stands of rolls on each side oi the hne of delivery of said feed rolls and nearer thereto than the first mentioned finishing stands, the last mentioned finishing stands adapted to run in the same direction as said feed rolls, and being staggered with respect to said first mentioned stands.

5. In a rolling mill, the combination with feed rolls for supplying metal to a finishing train, of a finishing train comprising stands of rolls on each side-of the line of delivery from said feed rolls but spaced therefrom, each of said stands running in opposite directions to said feed rolls, and stands of rolls on each side of the line of delivery of said feed rolls and nearer thereto than the first mentioned finishing stands,

the last mentioned finishing stands being staggered with respect to each other.

6 In a rolling mill, the combination with feed rolls for supplying metal to. a finishing train, of a finishing train comprising stands of rolls on each side of the line of delivery from said feed rolls but spaced -thereir(, m, each of said stands running in opposite directions to said feed rolls, and stands of rolls on each side of the line of delivery from said teed rolls but nearer thereto, than said first mentioned stands, said last mentioned stands adapted to run in the same direction as said feed rolls, and being in staggered relation to the corresponding first named stands and also in staggered relation to each other.

v7. In rolling mill, the combination with I feed rolls for supplying metal to a finishing train, and a guideivay leading from said feed rolls, of a finishing train comprising stands of rolls on each side of said guideway and spaced therefrom, adapted to run in the opposite direction to said feed rolls, additional stands of rolls on each side of said guideway and nearer thereto than said first mentioned stands, and adapted to run in the same direction as said feed rolls, a cooling bed, a pair of guiden'ays leading from each of said last mentioned stands of rolls to said cooling bed, and cross guideways connecting said pair of guideways and placed obliquely thereto.
