lVllVLL FOR ROLLING SEANILESS TUBING.

SPECIFICATION forming part of Letters Patent No. 718,476, dated January 13, 19,03.

Application tiled October 19, 1901. Serial. No. 79,212. lNo model.)

T all whom t may concern: Y

Beit known that we,` JOHN I-I. KING and ED- WARD M.WOLFE,citizens of the United States, residing at Beaverfalls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Mills forRolling Seamless Tubing, of which the following is a specification, reference being had therein to the accompanying drawio ings, forming part of this specilication, in

which- Figure lis a front elevation of our improved tube-rolling mill. Fig. 2 is a plan view thereof. Figs. 3 and 4 are cross-sectional views I5 on the lines III III and IV IV, respectively,

of Fig. 2. Y

Our invention refers to improvements in mills for rolling tubes, rods, bars, 85e.; and it consists in the construction and arrangement zo of the rolls, their housings, connections, and

driving mechanism, as shown in the drawings, whereby several sets of rolls are closely assembled and capable of performing a continuous series of rolling operations within a restricted area and the shortest time.

Generally the mill consists of two lines of rolls A and B, parallel to each other and mounted in housings 2', which are closely adjacent, the inner legs of each set of housings 3o resting on a common rail 3 and at the outer sides upon the usual independent rails 4E.

As will, be observed, each alternate set of housings is mounted in staggered arrangement and in proper position for the location 3 5 therein of alternate pairs of grooved rolls 5 5, each pair being successively in alinement with the lines A or B, respectively. The result of this arrangement is that the pair of rolls on one side is located about midway be- 4o tween the pair of rolls on the opposite side or at a corresponding distance to one side or the other of the end rolls and housings.

All of the rolls are mounted upon the same level, as are their spindles 6 6v and 7 7, the

lower and upper spindles of each set being geared together by toothed gearing 8. Both lower spindles, or both upper, if desired, are

' driven in opposite directions by any suitable gearing 9 from a shaft lO or other convenient 5o source of power or prime mover. As thus arranged, the rolls being rotated, as indicated by the arrows, Figs. 3 and 4, the piece to be rolled is first introduced between the first pair of rolls a, passing inwardly between the spindles' and 7 through suitable or conven- 55 ient guiding devices. The piece is then introduced between the pair of rolls b, passing inwardly between the spindles of the first pair of rolls, and this operation is repeated back and forth through rolls c and d until the piece emerges from the last pair of rolls, when it may be taken to the finishing-rolls or elsewhere, as desired. It will be understood lthat the number of sets of rolls may be increased or diminished as desired and that they may be assembled more or less closely adjacent to each other, according to the work in view. The mill is continuous in its operation, is very compact in construction, will effect a great economy in time and handling 7o of the pieces, and is simple and cheap in construction, while its advantages over a threehigh mill or over two separate mills will be readily appreciated by all those familiar with the art of rolling tubes or other similar articles.

Changes and variations may be made by the skilled mechanic in the details of construction or in the gearing by which the different sets of spindles are driven-as, for instance, pulleys, pinions, or sprocket-wheels may be substituted for the bevel-gearing 9, driven from a single prime mover through belting, cables, toothed gearing, or chains in opposite directions; but all such changes are contem- ,85 plated as within the scope of the following claims.

Having described our invention, what we claim isl. In a rolling-mill, the combination of two independent sets of roll-spindles and rolls, the rolls and spindles of one set being arranged in staggered relation to the rolls and spindles of the other set, with correspondingly-arranged housings, a driving element, and gearing connecting said driving element with the spindles of each set respectively, and necessitating the driving of said sets in opposite directions, substantially as set forth.

2. In a rolling-mill, the combination of two independent sets of roll-spindles and rolls, the rolls and spindles of one set being arranged Ioo in staggered relation to the rolls and spindles of the other set, with correspondingly-arranged housings, a driving element, and gearing connecting said driving element with the spindles of each set respectively, and necessitating the driving of said sets in opposite directions, and at the same speed, substantially as set forth.

3. In a rolling-mill, the combination of two independent sets of roll-spindles and rolls, the rolls and spindles of one set being arranged in staggered relation to the rolls and spindles of the other set, with correspondingly-arranged housings; a single driving element, and intervening gearing by which movement is transmitted therefrom to each set of rolls in opposite directions, substantially as set forth.

4:. In a rolling-mill, the combination of two independent sets of roll-spindles and rolls, the rolls and spindles of one set being arranged in staggered relation to the rolls and spindles of the other set, with correspondingly-arranged housings and independent adjusting means for each set of rolls; a single driving element, and intervening gearing by which movement is transmitted therefrom to each set of rolls in opposite directions, substantially as set forth.

5. In a rolling-mill, the combination with outer housing-supporting foundation-rails and an intermediate housing-supporting rail; two independent sets of housings mounted upon the outer and intermediate rails respectively, tWo independent sets of roll-spindles and rolls mounted in said housings, whereby the rolls and spindles of one set are arranged in staggered relation to the rolls and spindles of the other set, a driving element, and gearing connecting said driving element with the spindle of each set respectively, substantially as set forth.

In testimony whereof We afix our signatures in presence of two Witnesses.
