ROLLING-MILL.
Specification of Letters Patent. Patented Nov. 28,1916;
Application filed September 28, 1915. Serial No. 53,095.
I '0 all whom it may concern Be it known that I, JOHN S. WORTH, a citizen of the United States, and a resident of Coatesville, county of Chester, State of Pennsylvania, have invented certain Imdispense with frequent dressing and sizing of the rolls and to improve the product by obliterating the infinitesimal waves usually found in plates, which are due to the lost motion in the gearing.
In the accompanying drawings: Figure 1 is a front elevation of a rolling mill, illustrating my invention and showing the supporting rolls and the intermediate roll. driven independently; Fig. 2 illustrates a rolling mill in which the working rolls are driven independently from opposite sides; Fig. 3 is a view illustrating my improved independent drive in connection with a 3- high rolling mill, and Fig. 4 is a view illustrating my improved independent drive in connection with a 2-high rolling mill.
Referring to the drawings, 1 is the lower working roll. 2 is the upper working roll. 3 is the intermediate roll. 4 is the lower supporting roll and 5 is the upper supporting roll. These rolls-are mounted in housings 6 in the ordinary manner and the pressure is regulated by the set screws 7 at the upper ends of the housings.
In the present instance, I have illustrated horizontal steam engines as the driving power, but it will be understood that electric motors, or other types of engines, may be used without departing from the essential features of the invention.
8 is an engine having a crank shaft 11, which is connected to the lower supporting roll 4, Fig. 1, by a coupling shaft 12. The
coupling 12 is of the ordinary flexible type and the cou ling 12 is similar to the coupling 12, with the exception that the socket is flanged so that it can be secured to the flange on the end of the shaft 11. shaft 14,
9 1s an engine having a crank which is connected to the upper supporting roll 5 by a coupling shaft 15 and couplings 15 and 15 10 is an engine having a crank shaft 16 connected to the intermediate roll 3 by the coupling shaft 17 and couplings 17 and 17 The couplings shown allow for the free vertical movement of the rolls.
The working rolls 1 and 2 by the above arrangement are frictionally driven from the supporting rolls 4 and 5 respectively. These rolls are independently driven from the engines as above set forth.
In Fig. 2, I have shown the two working rolls 1 and 2 connected. directly to the shafts 11 and 11 of their respective engines, one on each side of the set of rolls in the present instance. The intermediate roll, in this instance, is not independently driven.
In Fig. 3, I have illustrated a 3-high mill in which the lower roll 1 is driven directly from the crank shaft 11 and the upper roll 2 is driven directly from the crank shaft 14:". In this case, also, the intermediate roll is not independently driven. In a 2-high mill the intermediate roll is dispensed with and the plate is rolled between the upper and the lower rolls, see Fig. 4. In this case, I have illustrated electric motors t) and 10 as substitutes for the reciprocating engines shown in Fig. l. The motor 9 is connected to the lower working roll 1 by a coupling shaft 11 and the motor 10 is connected to the upper working roll 2 by the shaft 14 Each of these shafts has flexible couplings and each motor shaft is provided with a fly wheel, as shown.
By the above arrangement I dispense with the use of stands of gearing which are now universally used in rolling mill practice for rolling plates and other products and, in the present method of driving through gearing, the rolls must hear about the same proportion to each other that the gears bear which drive them, consequently, frequent dressing and sizing of the rolls is necessary or there will be abreakage of the gears, as well as an unsatisfactory product.
By the use of the independent driving mechanism. I am enabled to keep thesurthe same, irrespective of their relative diameters. v
While I have shown the power units in the form of steam engines, it will .be understood that other power mechanism may be used, such as motors of difierent types.-
In Fig. 1, the cylinders 8 and 9 may be the high and low pressure cylinders of a compound engine, one cylinder being used for driving one of the rolls and the other cylinder can be used to drive the other roll.
The construction in which the working rolls are independently driven is claimed in a separate application filed' as a division on the 6th day of July, 1916, under Serial No. 107,810.
I claim:-
'1. A rolling mill having a plurality of rolls; and means for independently driving a plurality of said rolls.
2. The combination in a rolling mill, of two working rolls and an intermediate roll; and independent means for driving each of said working rolls and for driving the intermediate roll.
3. The combination in a rolling mill, of two working rolls; a supporting roll back of each working roll; an intermediate roll; and means for directly driving each supporting roll independently.
4. The combination in a rolling mill, of two working rolls and an intermediate roll; a supporting roll back of each working roll; independent means for directly driving each of said supporting rolls; and independent means for driving the intermediate roll, said working rolls being driven by their supporting rolls.
JOHN s. WORTH.
