ROLLING MILL. No. 284,700. Patented Sept. 11, 1883.

SAMUEL T. XVILLIAMS, OF TROY, NEW YORK, ASSIGNOR OF ONE-HALF TO ROBERT WV. HUNT, OF SAME PLACE.
ROLLING-MILL.
SPECIFICATION forming partof Letters Patent No. 284,700, dated September 11,1883.
Application filed December 27, 1882. (No model.)
To all whomit may concern:
Be it known that I, SAMUEL T. NVILLIAMs, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Rolling-Mills; and I dohereby declare the following to be a full, clear, and exact description of the invention, .such as will enable others skilledin the art to which it pertains to make and use the same; My invention relates to an improvement in mills for rolling railroad-rails, bars, plates,
and all masses of metal of similar shape.
Rolling-mills as heretofore constructed maybe classified under three heads: first, those I 5 having two rolls rotating in the same direction; second, those having three rolls, the upper and lower rolls being rotated in opposite directions; and, third, those having two rolls arranged to be reversed in the direction of their rotation between the successive passes of the article being rolled. Mills of the first class are objectionable 011 account of the great eX- penditure of time and labor involved in idly returning the article being: rolled from the 2 delivery to the entering side of the rolls. On the other hand, mills of the second class are objectionable on account of the expenditure of time and labor necessarily attendant upon raising and lowering the article being rolled to enter it between the upper and lower rolls,
5 while mills of the third class are objectionable on account of the time involved in reversing the rolls between the successive passes of the article being rolled, and also on account of the 3 5 great wear on the rolls and their associated mechanism which the reversing entails.
My invention com'prehends the construction of a rolling-mill of the character designated which shall obviate the objections incident to 40 these classes of mills, above referred to, and which shall, combine simplicity and cheapness of construction with durability and efficiency in use. p
\Vith these ends in view my invention con- 5 sists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.
The accompanying drawing represents a plan view of a rolling-mill embodying my in vention.
A and B respectively represent the upper rolls of two sets of rolls placed end to end and independently rotated in opposite directions, as indicated by arrows on the fly-wheel (I, by power applied through the pinions D.
A table, E, to be hereinafter designated as the entering-table, and consisting of aseries of rollers, F, mounted in suitable frame-work, is located in front of the entering side of the rolls A, several. or all of the rollersF being rotated in the direction of the said rolls by power communicated to them through a shaft, G, provided with gears H, arranged to mesh with similar gears, I, attached to the rollers.
A table, E, to be hereinafter designated as the delivery-table, and similar in construction to the entering-table E, is located in front of the delivery side of the rolls A, and adapted to receive the article being rolled as it is delivered from them, No provision is shown for rotating the rollers F of this table; but this may be provided for, if found desirable. Cylinders J, operating from the outer edge of and at right angles with the said delivery-table, are provided with suitable water or steam connections, (not herein shown,) according to the motor employed in actuating them. The outer ends of the piston-rods K of the said cylinders are adapted to engage with the articles delivered onto the table E, and move them transversely'over it and onto the entering-table L of the rolls B, which, as before described, rotate in reverse direction from. the rolls A. The said entering-table L, which is substantially the same in construction as the tables E and E, is parallel with and located in or about the same horizontal plane as the latter. The rollers M of this table are rotated in the direction of the rolls B by power transmitted to them through the shaft N, provided with gears O, and meshing with similar gears, P, attached to the rollers. The articles being rolled are delivered from the rolls B onto the deliverytable L, the same being substantially the same in construction as the tables already described,
and parallel 'with and located in or about the same plane as the entering-tableE of the rolls A. Cylinders J, operating from the outer edge of and at right angles with the said delivery-table L, are connected with suitable IOO steam or water mains, (not herein shown,) according to the motor employed in actuating them. The outer ends of the piston-rods K are adapted to be engaged with the articles ,delivered onto the table L by the rolls B and ment of rolls, tables, and the devices for moving the article being rolled, the transit of the two sets of rolls is made very rapidly andwith comparatively little manual intervention, the
article being reduced being passed through each set of rolls once in every uninterrupted circuit of the tables. \Vhile it is apparent that the article to be rolled may be started from either of the entering-tables, let it be assumed, for the purpose of illustration, that it is started from the entering-table E of the rolls A, through which it passes, being delivcred onto the delivery-table E, from which it is immediately transferred to the enteringtable L of the rolls B by the piston-rods K. From the said table L it is passed through the rolls B and delivered onto the delivery-table L, from which it is transferred by the pistonrods K to the table E, from which it first started, the article being continued in the circuit of the tables, as described, until it is reduced to the desired form. Of course it is not necessary to pass the article being rolled successively through the two sets of rolls, for it maybe returned idly over and repassed through either set of rolls as many times as need be.
In the improved mill herein described the wear of the mechanism, the time elapsing between the successive passes, and the labor of manipulation are reduced to the minimum, whereby all operations under it are cheapened and facilitated. \Vhile the arrangement of placing the rolls of the two sets end to end is probably more practical than any other, they may be placed at any angle desired. Again, the invention is not limited to the devices shown for transferring the article being rolled from the delivery to the entering tables of the respective sets of rolls, for any other suitable devices may be employed instead. N or is the invention restricted to the particular construction of rolls, tables, and associated mechanism herein set forth. I would therefore have it understood that I do not limit myself to the construction and combination of parts herein shown and described, but hold myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. An improved rolling-mill, consisting of two sets of rolls arranged to rotate in opposite directions, of stationary entering and delivery tables for each set of rolls, and ofmeans for transferring the article being rolled transversely over the delivery-tables, and onto the entering-tables adjoining them, substantially as set forth.
of the delivery-tables, and arranged to transfer the article being rolled transversely over them and onto the adjoining entering-tables,
substantially as set forth.
3. An improved rolling-mill, consisting of two sets of rolls arranged to rotate in opposite directions, of stationary entering anddelivery tables for each set of rolls, and of pistons operating from the outer edges of the delivery-tables, and arranged to transfer the article being rolled transversely over them and onto the adjoining entering-tables, substantially as set forth.
4. An improved rolling-mill, consisting of two sets of rolls arranged to rotate in opposite directions, of stationary entering and delivery tables for each set of rolls, said tables being composed of rollers mounted in suitable frames, of means to rotate the rollers of the entering-tables in the direction of their respective rolls, and of means for transferring the article being rolled transversely over the delivery-tables and onto the entering-tables adjoining them, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
