ROLLING-MILL.

Specification of Letters Patent.

Patented Oct. 8, 1912.

To all whom it may concern:

Be it known that I, VICTOR E. EDWARDS, a citizen of the United States, residing at Worcester, in the county of \Vorccster and Commonwealth of Massachusetts, have in-E vented a new and useful Improvement 1n, Rolling-Mills, of which the following is a' specification, accompanied by draw ngs forming a part of the same, in which Figure 1 represents in plan view a roll-; ing mill embodying my-invention. F1g. 1s a plan View of a portion of the rolling mill, showing a changed position of the trains of' rolls from that represented in Fig. 1. Fig.9

'3 is a sectional view on a larger scale on line 3-3 Fig. 1, showing two trains of rolls, in end elevation and Fig. 4 isa side elcva-' tion of one of the movable trains of rolls.

Similar reference letters and figures re't'erf to similar parts in the diiierent views. v

My present invent-ion relates to a rolling; mill for the continuous reduction of a metal bar, comprising a series of pairs of rolls each journaled in a roll housing and providcd with channels or repeaters for con-. ducting a metal bar from one pair of rolls to another consecutively, and my invention. relates particularly to the finishing rolls of' the series by which the exact dimensions required are given to the finished product.

The object of my invention is to enable the product to be changed at will without necessitating a prolonged interruption of; the operation of the mill, such as would be required to change one or more pairs in their respective housings.

By my improvement I divide the rolls of the finishing mills into separate trains of rolls, with the roll housings of each train of rolls mounted upon bases which are'longitudinally movable on tracks or ways, and? I provide duplicate trains of rolls, simi larly mounted and movable longitudinally on contiguous parallel ways with actuating mechanism for movingeach of the dup icate trains of rolls into and out of operative position.

Referring to the accompanying drawings 1. denotes rolls for the initial reduction of a heated billet as it is taken from the furnace and the rolls 2 and 3 form what is known the finishing mill in which a metal bar delivered from the rolls 1 is reduced to the required size and shape and delivered upon a cooling bed 4. The rolls 2 are journaled in pairs in housings 5 which are mounted upon a base (i longitudinally movable on a track 7 and constituting a single train of rolls A which are capable of being moved into and out of operative position on the track 7. The rolls 3, comprise the two last pair of rolls in the finishing mill and are journalcd in housings 8 similarly supported on a base i), constituting a train B capable of being moved on the track 7 in and out of operative position. The metal bar received from the rolls 1 is conducted through channels or repeaters in the usual manner from one pair of rolls to the next succeeding pair of rolls. The repeaters comprise curved sections 10 supported upon the floor 11 of the mill and removable straight sections 12 connecting. the curved sections with the passes of the rolls.

Adjacent to and parallel to the track 7 is a similar track 13 and longitudinally movable thereon are the bases 14 and 15. On the base 1-1 are mounted roll housings 16 in which are journaled the rolls l7 constituting a single train C. On the base 15 are mounted the roll housings 18 in which are journaled the rolls 19 constituting a single train D. The bases and housings of the trains C and D are a duplicate of those in trains A and B and as the trains C and D are capable of being substituted for the trains A and B I term the former substitutional and the latter operative trains.

I do not confine myself to any particular means for rotating the rolls of the respective trains but I prefer to employ electric motors 20 mounted upon and movable with the bases of the several trains. I do not confine myself Ito any specific means for moving the trains longitudinally on the tracks 7 and 13 but this may be conveniently accomplished, as shown in the accompanying drawings, by providing the roa s-as bases of the trains with cuts indicated the broken lines'l engaging screws 23, 2 and The screws and are rotated simultaneously in opposite directions by right and left hand Worm gear con nections 26 and 2'l WllJl1 ashei't 28. screws 24 and 25 are similarly rotated in opposite clirectiohs by right and left hand Worm gear connections 26 and 27 with a shaft 29 the shafts 28 and 29 are driven by motors 30. The tracks and the housings of the trains, for convenience, are depressed as shown in Fig. 3 in order to bring the passes in the horizontal plane of the curved sections 10 of the repeaters. In Fig. 1 the trains A and B are shown inoperative position, but in case a change is desired in the shapeor size, in cross section, of the finished product suitable rolls 19 therefor are installed iii the train D without interrupting the operatiorr of therolls in train B. simultaneously operating the screws 22 and 23 the trains l3 and D are moved in opposite directions on the tracks '1 and 13, moving the train ll out of operative position and the train D into operative position as shown in. Fig. 53, each train being moved as a ,unit, The removable straight sections of the repeaters, which are of ditl'erent lengths on opposite sides of the rolls are transferred and the operation. of mill may he resumed with the trains A and ill in operative posi ion, in like manner the trains A C may he shifted bodily on the tracks '2' and 13 by the rotation of the screws and ihe consecutive reduction oi a metal 2". bar therefore may he carried on through.

the joint operation of either trains A and B as shown in. Fig. l, of trains and-D, of trains C and or trains C and 3. Whenever any change of rolls becomes necessary in order to change the track or for other reasons such change can he made in the trains which are in inoperative position and the trains quickly shifted with but slight interruption 1n-the operation the mill. l

In practice any slight changes in the shape or size or the product can be made by simply shifting the trains B and B thereby changing the two last pair of rolls in the mill. A division of the series of rolls torming the finishing mill may he made at any desired point in the reduction of a metal ban but in practice I prefer to place the two last pairs of rollsin a single train.
