FRANCIS H. TREAT, OF 'JOLIET, ILLINOIS, ASSIGNOR OF TWVO-THIRDS TO HORACE S. SMITH AND CHARLES PETTIGREW, BOTH OF SAME PLACE.

ROLLING-MILL.

SPECIFICATION forming part; of Letters Patent No. 333,431, dated December 29,1885.

Application filed September 15!, 1883. Serial No. 106,844.

To all whom, it may concern:

Be it known that 'I, FRANCIS H. TREAT, a citizen of the United States, residing at Joliet, in the county ofVVill and State of Illinois, have invented certain new and useful Improvements in Rolling-Mills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to 0 make and use the same.

This invent-ion relates to rolling-mills for rolling a bloom or billet of metal into the required shape by the action of two or more successive passes, and where it is required to turn the piece on its axis after it has emerged from a pass and before it is fed into the next pass.

My invention consists of a billet-turner which has the form of a sleeve, the eye of which conforms in cross-section approximately to the cross-sectional contour of the piece it is designed to receive and turn, and which is suitably journaled so that it may be turned on its axis to turn the piece it encircles any desired fraction of a full turn.

In order that my invention maybe clearly understood, I have illustrated in the annexed drawings a convenient way of applying it to an obliquely ascending and descending feedtable adapted for use in connection with a set of three-high rolls, and will proceed to describe such a form of the invention in detail, and will also briefly indicate other forms and modes of application thereof.

Figure 1 is a transverse section of such obliquely ascending and descending feed-table provided with my billet-turner. Fig. 2 is a longitudinal section of a portion of such feedtable. Fig. 3 represents a side elevation thereof, showing the three-high rolls in cross-section. Fig. 4 represents a plan View of the same.

The same letters of reference indicate identical parts in all the figures.

The feed-table A, provided with lines of power-driven feed-rollers B C D, is supported upon the arm E of a rock-shaft, E, by means of a pair or pairs of diverging struts, A A, connected at their lower ends by a coupling, which is pivoted to said arm E. A radiuslink, F, journaled at f on a suitable fixed (No model.)

stand, F, is pivoted at a to one side of the table A. By rocking the shaft E, which may be effected by a single-acting hydraulic cylinder, the table will be lifted or lowered, as 5 the case may be, ascending or descending in oblique directions, so that the lines of feedrollers will be carried from the position shown in full lines in Fig. 1, where they would face the lower passes of the three-high rolls, to the position shown in dotted lines, where they would face the alternating upper passes of such rolls, or vice versa.

The billet-turner consists of a sleeve, G, and a bearing, H, in which the sleeve is journaled. The sleeve must be made trumpet-mouthed at the end'which is to face the rolls, and may be made trumpet-mouthed at both ends, as shown. The contracted portion of the eye of the sleeve is angular in cross-section, and conforms approximately to the cross-scctional contour of the billet which it is designed to turn. In this instance the bearing H is bifurcated, and the sleeve provided with a pair of collars, g g, to hold it in place between the two branches of the bearing. One of these billet-turners is arranged in each line of feedrollers in this instance, and provided with an upwardly-projecting arm, G. All the arms G are pivoted to a connecting-rod, F one end 80 of which is pivoted at f to an upwardly-pro- 1 jecting arm, F formed on the radius-link F. The length of the arms G on the sleeve G is so proportioned with reference to the distance between the journalf and pivot f of the radiuslink and the throw of arm E of rock-shaft E that the sleeves will be turned a quarter-turn during each ascent and descent of the feedtable; hence the billet would be turned automatically a quarter-turn on each line of feedrollers in carrying it from any pass to the next succeeding pass. The same result of an automatic turn of the billet-turner may be produced by a radiuslink so constructed and arranged as to cause the feed-rollers to occupy the same vertical planes when the feed-table is up which they occupy when the feed-table is down. By a suitable variation of the lengths of arms G or F the sleeves G may be caused to turn more or less than a quarterturn, and by connecting the arms G by separate connecting-rods at different points to the radius-line the sleeves G may be caused to turn through arcs of different lengths,

My billet-turner may be used in connection with two-high rolls, in which case the point 5 f of the connectingmod F would be fixed so table I do not claim, per se, in this patent.

that the turning of sleeve G would be effected by the lateral horizontal movements of the billet-turner in shifting it back and forth between the passes.

Automatic means other than those described may be used for turning the sleeve of the billetturner-as, for instance, a rack and pinionor it may be turned even by hand, in which case suitable means should be provided for locking it after each turn.

Anti-friction rollers may be arranged on the sleeve of the billet-turner to diminish the friction on the billet as it is fed into or out of said sleeve,

The obliquely ascending and descending It will be claimed in another patent.

I claim as my invention- 1. The combination, substantially as before set forth, with the rolls of a rolling-mill, of a billet-turner composed of a trumpet-mouthed sleeve, the eye of which is angular in crosssection, and a stand or hearing on which said sleeve is journaled. I

2. The combination, substantially as before set forth, of the radius-link, the feed-table pivoted thereto, means, substantially such as described, for supporting and lifting and depressing said feed-table, the billet-turner which is mounted on the feed-table, and the journaled sleeve of which is provided with an arm, and a rod connecting the said arm with the radiuslink.

In testimony whereof I afiix my signature in presence of twovwitnesses.
