' Specification of Letters Patent. Application filed March 8, 1912. Serial No. 882,878."

p 7 To all whom it may concern:

Be it'known that I, Josarn FAWELL, re siding at Pittsburgh, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Rolling-Mills, of which improvemerits the following is a specification.

.In an application Serial No. 678,046, filed February 16, 1912,:1 have described and claimed "certain improvements in rolling' mill plants wherein roughing and finishing mills, both of the three high type, are arthat there may ranged with the rolls of the several mills in or approximately in a common vertical plane and the rolls ofthe several mills driven by a common motor. It occasionally happens not 'be any orders requiringthe operation of the finishing mills, although there may be orders for material such as billets, which can be produced in a roughing mill, and preferably in one of the two high reversing type.

The invention described herein has for its object the combination with a roughing mill convertible from a nonreversible three high type to a reversible two high type of a reversible motor and a train of rolls of the three high type driven through rolls of the roughing mill.

In the accompanying drawings formin a part of this specification, Figure 1 is ap an view of a plant embodying my improvement; 2 is an elevation showing the mill adjusted for the combined operation of the roughing and finishing mills; Fig. 3 is a similar view showing the mill adjusted for the operation of the roughing mill alone; Fig. 4 isa sectional elevation of the three high roughing mill showing the feed table on one side thereof, and Fig. 5 is a similar view of a two high mill showing the table with ingot manipulating means on the reoeiving side of the mill.

In the practice of my invention I employ a reversible motor A of any suitable form or construction. The shaft 1 of this motor is operatively connected in any desired manner to the journal of one, preferably the middle one, of the three high stand of pinions B,through which the rolls of the roughing mill 0 are driven. This mill is so constructed that it may be readily converted from a three to a two high type of mill. The housings 2 have their windows of suflicient length t permit of the arrangement therein of the bearings of the three rolls 3. Interchangeable caps 4 and 5 are provided, one of the caps as 4: being provided with holding down screws 6 for maintaining the rolls in proper operative relation. The

housing cap 5 has mounted thereon the fluid pressure cylinders 7 having their plungers 8 connected to the cross-head 9 which in order to reduce the height of the mill is passed through the windows of the housings, as shown in 'Fig. 3. .This cross-head is ada ted to be connected to the journal boxes 0 the upper roll of the two high mill shownin always necessary, to drive all of the rolls,

which have the journals at one end con- Patented Dec. 10, 1912. i

nected by spindles 13 to the pinions of the three high stand B. When it is desired to operate the three high finishing mills E, F, G, etc., a journal of one of the rolls 3 is connected by a spindle 14 to the journal of one of the pinions of the three high stand D, as shown in Fig. 2. The journals of the pinions of stand D are connected by spindles 15 to the journals at one end of the rollsof stand E and the opposite ends of these rolls are similarly connected to the.

rolls of stand F, and so on through the series of finishing mills.

When the three high mill C is converted to a two as hereinbefore'described, the rolls 12 are connected by spindles to two of the pinions of the stand B,- said connection being so constructed as to permit of the vertical adjustment of the upper one of the rolls 12. 'It will beunderstood that when the roughing'mill has been converted to the two high type, the motor A will be so operated as to rotate the rolls 12 first in one direction and then in the reverse direction.

As described and shown in the application referred to feed tables H and I are provided 'on both sides of the line of mills, the table on the delivery side of the line of mills being laterally movable to positions in is laterally movable to positions in line with the finishing mills, and a table K having only a vertical movement is arranged in line with the mill Con the receiving side thereof, and said table is provided with a manipulator or billet turning and shifting device 18 to be used in Connection with the mill when converted to the two high type, The tables H I and K have portions adjacent to the mills vertically movable, so tha-tthey may be used to serve the roughing mill when of the three high type and also the finishing mills. As stated in said application the vertical movements of the tables H and I are variable, as is required by the difference in diameter of the roughing and finishing rolls. The vertical movements of the tables can be efl ected by any, suitable means as eccentrics 16 and 17 arranged at different distances from the pivotal points of the tables, as fully set forth in said application. It will be understood that when the two high reversible rough mill is employed neither lateral nor vertical movement .of thetable I is required and that the direction of rotation of the rollers of the feed K and I is reversed with the reversal of the rolls 12.

It will be readily understood by those skilled in the art, that by my improvement the several units of my improved plant can be operated simultaneously when required, and when the operation of the finishing mills is not justified, that they can be disconnected, and the roughing mill converted to arreversible mill and entirely different articles rolled thereon which heretofore required a separate and independent roughing mill engine, etc.

I claim herein as my invention:

1. In a rolling mill plant, the combination of a reversing engine, a three high stand of pinions, a roughing mill convertible from a three to a two high type, and detachable driving connections from the pinions to the ,rolls of the roughing mill.

2. In a rolling mill plant, the combination of a reversing engine, a three high stand of pinions, a roughing mill convertible from a three high to a two high type, detachable connections from the pinions to the rolls, a

train of three high finishing mills and a detachable connection from a roll of the roughing mill to the rolls of the finishing train.

' In testimony whereof, I have hereunto set my hand.

JOSEPH FAWELL.
