W. H. JARVIS. GUIDE FOR ROLLING MILLS- No. 330,708. Patented Nov. 17,1885.

NITED STATES PATENT ()FFIGE.

WILLIAM H. JARVIS, OF ANSONIA, CONNECTICUT, ASSIGNOR TO WALLACE 8t SONS, OF SAME PLACE.

GUIDE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 330,708, dated November 17, 1885.

Application filed September 25, 1885. Serial No. 178,120.

To all whom it may concern:

Be it known that I, WM. H. JARVIS, of Ansonia, in the county of New Haven and State of Connecticut, have invented a new Improvement in Guides for Rolling-Mills; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a section through the rolls of the rolling-mill at the groove, showing the inner face of one guide; Fig. 2, a front view of the rolls of the mill,showing the outer end of the two guides; Fig. 3, ahor'izontal longitudinal section of one of the guides.

This invention relates to an improvement in the guides used in rolling-mills to guide the rod or barinto the rolls. As usually constructed, these guides consist of pieces of metal, generally about two inches high, arranged one each side of the path of the bar into the rolls. At their forward end they are reduced corresponding to the shape of the rolls, and so as to enter between the rolls nearly to the point where the rolls take the metal, as indicated at Fig. 1, the guides presenting a flat smooth surface, against which the bar will run. To properly guide the bar or rods into the rolls, it is necessary that the guides should extend a considerable distance from the rolls, so as to locate the rod in its proper parallelism with the grooves in the roll. The opening at the ends between the guides can only be substantially the width of the bar which is to be rolled, and the hot rod is liable to be abutted against the end of the guides in entering, so as to interrupt or interfere with the proper introduction of the rod.

The object of my invention is to facilitate the introduction of the rod; to and the running of it through the guides; and it consists in constructing the guides with a recess at (No model.)

their outer ends, upon the inner face, with a guide-roll arranged in each of said recesses on a vertical axis, the face of the roll pro ecting slightly beyond the face of the gulde, as more fully hereinafter described.

A represents one roll, and B the other roll, of a rolling-mill; C the guides, which are ill outline substantially of the usual form. At the extreme outer end, and upon the inner face, a recess, D, is cut, so as to leave an ear, b, upon both the upper and lower side. Into this recess a roll, E, is arranged on a vertlcal axis, its face projecting slightly beyond the.

inner face of the guide, as shown, and so that the rolls appear at the entrance between the two guides, as seen in Fig. 2, and serve to receive the bar between them, and so that should the rod abut against either of the rolls the roll will revolve and instantly turn the end inward. so that little care is required in the introduction of the rod between-the guides, the rolls not only facilitating the entrance to the guides, but the movement of the rod between the guides.

Two of these guides are arrangedone each side the grooves-in the rolls A B, through which the rod is to pass, and as seen in Fig. 2.

I do not claim, broadly, an anti-friction roll in guides for rolling-mills.

I claim The guide C for rollingmills, each constructed with a recess, D, upon their face and at their outer end, combined with a vertical roll, E, arranged in each of said recesses upon a vertical axis, the surface of the said roll exposed through the recesses at the outer end of the guides, substantially as described, and so that said rolls form the entrance between the said guides.

W. H. JARVIS.
