Application filed July 1, 1908. Serial No. 441,375.

To all wizor/t it may concern:

Be it known that I, Josnrrr FAwnLn, residing at Pitt-sburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered a certain new and useful Improvement in Rolling-Mills, of which improvement the following is a specification.

The invention described herein relates to i part of this specification Figure 1 is a plan view of a mill embodying my improvements; Fig. 2 shows side elevations illustrating the arrangement of the two stands of horizontal rolls. Fig.3 is a sectional view on a plane indicated by the line III-III Fig. 1. Fig. 4-. is a plan view illustrating a modification of the mill shown in Fig. 1. Fig. 5 is a sectional diagram the plane of section being in dicated by the line VV Fig. 4. Fig. 6 is a plan view illustrating a further modification of my improved mill; Fig. 7 is a plan on an enlarged scale of the rolls and feed rollers shown in Fig. 6 and Fig. 8 is an elevation of a housing used in the mill shown in Figs. 7 and 8.

In the mill shown in Figs. 1 and 5, inclu sive, I employ two stands A and B of horizontal rolls arranged out of line with each other, but in such oroximity as will permit of the easy trans er of the article being rolled from the delivery side of one stand, as A, to the feed side of the other stand of rolls B. In connection with these two stands of horizontal rolls, I employ vertical rolls arranged respectively in suitable relation with two stands of horizontal rolls.

In the arrangement shown in Figs. 1, 2

and 3, provision is made for driving both.

stands of horizontal rolls and the vertical rolls from a common motor D through suitstand B to feed in the opposite direction.

As shown in Figs. v1, 2 and 3, two series of feed rollers 2 and 8, are arranged respectlvely on opposite sides of the mill and are lndependently driven by reversible means, so

that each series will act at one time to deliver the article and when reversed to receive the article being rolled. \Vhile the vertical rolls might-be arranged in two separate stands, it is preferred to employ the arrangement shown in Fig. 1, consisting of an intermediate vertical roll 4 and two outside vertical rolls 5 and 6, the central roll is arranged so that its periphery will extend into the line of movement of the article delivered from the stand of rolls A and also into the line of delivery of thearticle from the stand of rolls B, so that the same rolls can be used for edging articles passing through these two stands without any reversal of its direction of rotation. Provision is made by means well known in the art for adjusting:

the outer rolls 5 and toward and from the intermediate vertical "rell. The vertical rolls are driven from the motor E through a suitable shaft, the roll 5 being driven so as to have a peripheral movement in the same direction as the roll A, while the roll 6 has a peripheral movement in the direction of rolls By reference to Figs. 1, 2 and 3 it will be seen that in case the stand of rolls A were formed by two horizontal rolls, the driving connection to the lower roll would interfere with the feed of articles being delivered by the stand of rolls B. In order to overcome this objection three-high rolls are employed in stand A, the intermediate roll being driven by frictional contact with the lower roll. This arrangement permits of the driving connection of the lower roll passing below the feed rollers 2-.

In lieu of using an intermediate roll as shown in Figs. 2 and 3, in order that. an

article may pass out along the feed rollers 2 from the vertical rolls, the two stands of horizontal rolls may be independently driven, or driven by independent motors, as indicated in Fig. st, the couplings 7 for the stand of rolls A ext-ending out on one side of the mill and those for the stand of rolls B extending out from the opposite side'of the mill. In this construction the journals on the inner ends of the lower rolls areprovided with studsor projections 8 which I extend beyond the center housings and form journal pins for one of the rollers as 2 or 3- of each series. These rollers are provided with journals at their opposite ends on driving the horizontal rolls.

'linewith the stand of rolls B and its verwhich are secured ear wheels 9 so as to permit their being riven by the motor or motors 10 driving the other rollers of the series. As will be readily understood, these rollers 2 and 3 are rotated in the reverse direction to that of the rolls by which they are supported.

In the arrangement shown in Fig. at the vertical rolls may be driven by an independent motor if desired, or the shaft 11 for driving these vertical rolls may be extended out on each side of the mill and be connected by suitable gearing to the motors In such an arrangement while an article is passing through the stand I; and the vertical rolls in line therewith these two stands of rolls, 1 2'. 6., the horizontal and vertical, will'be drivenby a common motor which will also be assisted by the motor employed for driving the stand of rolls B, the latter running idle at this time.

In using the mills shown in Figs. 1 and. t the article is placed upon the feed tab t- "2 and is fedthereby in between the rolls of stand A and the vertical rolls in line therewith. lVhen the article has passed beyond the housings of the vertical rolls the motors ofthe feed tables are stopped and the ingot shifted by the head or abutment l2 over to tical rolls. The feed rollers are now rotated in the opposite direction so as to feed the article into the rolls B through the vertical rolls into position where it can be again shifted in the opposite direction by the hcad 12*. It will be observed during this operation that although the article is moved in opposite directions there is no reversal ot any of the rolls either horizontal or vertical. The transfer device consists of a head 12 can ried by guide arms 13 and operated by tiuid pressure cylinders 14.

The mill shown in Figs. 6 and 7 consists of two horizontal stands of rolls A and i5 separately driven and arranged in ditl'ercnt lines of feed and a stand of vertical rolls arranged in tandem to one of the stands ot horizontal mills and is driven :t romthe motor employed for operating the other stand of horizontal rolls. In this mill two independent teed tables E and l arremployed, the rollers of which will rotate constantly in the same direction as the rolls to which they feed and from which they receive the article. The article is transferred from one feed table to the other by means of a pushing mechanism substantially such as that shown in Fig. l, the article passing over rails 15 connecting such lines of feed rollers. In opc'ating this mill the article will be placed on the table l: of the stand of rolls A and will be ted thereby between such rolls. During reduction by rolls A, the rolls B and C will be idle and although the rolls C tea are designed to be operated by the motor of rolls A, such motor will not be called upon to do any work with the rolls C while the article is being reduced by rolls A as tlu rolls C are in the line of feed of the rolls B. When the article is transferred onto the table F for the rolls C and 13, it will be carried by such feed rollers between such vertical rolls, and then between the rolls B. During this movement of the article the rolls U will be operated by the motor the rolls of stand A and the rolls B by their own motor, so that. although the article is at this time being operated on by both stands of rolls, cach stand will be independently driven by a separate motor whose only load will bc that of the rolls operating on the article. lt is characte. "tic of this arrange ment that although three stands of rolls are driven by two motors, the latter are not; overloaded, but each is called upon to operate only one stand of rolls at a tiinc.

I claim herein as my invention:
