ROLLING-MILL.
SPECIFICATION forming part of Letters Patent No. 427,349, dated May 6, 1890. Application filed December 22, 1888. Serial No. 294,404. (No model.)
To all whom it may concern.-
Be it known that I, ARTHUR J. MOXHAM, of J ohnstown, in the county of Cambria and State of Pennsylvania, have invented a certain new and useful Improvement in Rollin g- Mills, which invention is fully set forth and illustrated in the following specification and accompanying drawings.
.The object of this invention is to facilitate the rolling of metal shapes in cases where side rolling may be advantageously practiced.
The invention will first be described in detail, and then particularly set forth in the claims.
In the accompanying drawings, Figure 1 illustrates in end elevation removable housings for the main rolls, and also shows the necks of the main rolls in cross-section and a side roll and its frame in place. Fig. 2 shows in front elevation the parts shown in Fig. 1, part of the housing being partly cut away where the side-roll frame is attached. Fig. 3 shows on an enlarged scale in plan a side roll and its frame detached. Fig. 4 shows a side elevation of Fig. 3 viewed from the side indicated by the point 00 in said figure. Fig. 5 shows partlyin cross-section a side roll. Fig. 6 shows in perspective the upper portion of a side-roll frame detached from the other parts of said frame. Fig. 7 shows in perspective the lower portion of the side-roll frame.
The several parts of said figures are inclicated in the following description by reference-letters, like parts bearing the same letters.
The housings containing the main rolls are indicated by the letter H, therolls by the letter R, and the necks of the same bythe letter N. These housings may be of the ordinary type, and, as shown in the drawings, are provided at their bases with hinged bolts X, by which they are secured to a bed-plate Y, as heretofore practiced, for the removal of the rolls and housings without detaching the said parts from each other. The rolls are thus borne in a housing removably secured to a foundation or bed-plate.
The side-roll frame proper consists of a face-plate A, provided with elongated holes or slots at, and a body l3, all in one piece. Said face-plate is cut away at its top and bottom, as at e, to permit of the passage of the rollnecks N through the same. The upper portion at e is shown as cut in a curve. The lower portion (3 is shown cut away square or angular. Either or both of such shapes will body B, the bolts used being preferably recessed and passing through the holes f in F and through the holes I) in B. The under part of the upper portion F is provided with. an annular space (Z, like the upper face of the lower portion 13, and through both portions F and B is an opening E for the side-roll shaft.
Between F and B in said annular space is placed the side roll S. Such side roll may be of different peripheral shapes or contours, as shown in Figs. 1 and 2 and in Fig. 5, according to the work to be done by such side ro1l.
In all cases, however, the side roll is provided with a central boss 8 and a shaft H, either inserted or keyed in or cast as part of said roll.
Said shaft finds its bearings in the openings E E, which may be babbitted or provided with an inserted bearing of any anti-friction metal. When the portions of the side-roll frame are assembled with the side roll between them, as shown, the boss 8 of the side roll secures a steady rotation of the side roll S, while the large bearings E resist and take up the side thrust upon said roll. secured the necessity called for in rollingmill workthat the parts be not only of great strength, but accurate and exact in their working properties.
The upper portion F. of the side-roll frame is provided with two brasses G, upon which the neck of the upper main roll rests and rotates, and these brasses are made adjustable by means of liners underneath them, without disturbing the side-roll frame, and the whole frame can also, if desired, be made adjustable by liners inserted underneath its lower portion B.
Thus is ICO The purpose of the annular space d d, formed in the upper and lower portions F and B, respectively, is as follows: A certain mass of metal is needed around the bearings at E E. If a narrow-faced side roll is used, as in Figs. 1 and 2, no difficulty occurs; but if a wide-faced side roll is used, as in Fig. 5, such wide face and ample bearing can be secured by undercutting the roll, as shown in Fig. 5 at a u, and providing the annular space (Z for the wide face of the roll, as shown in Figs. 6 and 7. Thus is secured both a wide face and a large shaft-bearing for the side roll. The parts F and B can be made both detached from the face-plate A, if desired, though it is better to have them integral with either the lower portion B, as shown, or with the upper portion F, as may be done if desired. The action and cooperation of the side roll S with the main rolls Ris as below described. The bottom main roll being placed in the housings H, the side-roll frame-pieces are next inserted, which fill the space between the housing-standards, the lower part B of the side-roll frame resting on liners L, and these liners in their turn resting on the offset M of the housing-standards, as shown in Fig. In this position the side-roll frame spans the lower neck of the bottom roll. The side roll is then adjusted by the liner or liners L to the proper height to suit the groove or pass in the rolls with which it is to coact. The top roll is then put into place, its neck resting 011 the brasses G, provided in the upper portion F of the side-roll frame. The top roll is then adjusted by liners under these brasses. The combined roll-carriage and side-roll frame is adjusted sidewise by means of the four bolts, which pass through the housing-standards and through the holes a a in the faceplate A. It is better, when said side-roll frame has been adjusted, to insert liners between the face-plate A and the face of the housing-standards, and then to tighten the bolts up. The whole structure then becomes as rigid as one mass, and ready for the rolling to begin.
By the arrangements thus described the whole space between the roll-necks N is available for the working parts of the side roll and frame, and the maximum of strength and rollbearing is secured.
The dotted lines to the left of Fig. 5 show the shape of the remainder'of the groove or pass in the main rolls, with which the side roll shown in said figure coacts, though of course many different shapes of such side roll can be employed to suit the shape of rail-section desired to be rolled by the agency of a side roll; but one pass is shown in the main rolls, the pass which co-operates with the side roll, for it is obvious that the other passes may be of very many shapes, as desired.
The holes a in the face-plate A are elongated for the purpose of vertical adjustment of the same.
Having thus fully described my said improvement in rolling-mills, as of my invention 1 claim- 1. A side-roll frame for rolling-mills, consisting of separable portions, each having an annular recess for the face of a side roll and a central bearing for the side-roll shaft.
2. A side-roll frame for rolling-mills, consisting of separable portions provided with a flanged face-plate located on the outside of said side-roll frame, and with central bearings for the shaft of a side roll.
A side roll for rolling-mills, provided with a wide face, as V, a central shaft, as H, and an undercut portion, as a, substantially as and for the purposes set forth.
