GUIDE FOR ROLLING MILLS Filed June 22. 1927 Patented Oct. 6, 1931 UNITED STATES. PATENT OFFICE GEORGE' W. 'SILLS, OI CHICAGO, ILLINOIS, ASSIGNOR, BY LIESNE ASSIGNMENTS, T

REPUBLIC s 'nEL CORPORATION, on JERSEY Application filed June 22,

My invention relates to new and useful improvements in mechanism for guiding metallic shapes in rolling mills, and is especially useful to change the path of the metal more or less between successive passes without bodily reversing it in its general line of motion, and as a straightener for rolling metal. The invention consists in the organizations and arangements of parts hereinafter described and claimed, and is illustrated in practical embodiment in the accompanying drawings in which, Fig. 1 is a diagrammatic view showing two sets of rolls in axial alinement and a plurality of guides associated therewith; Fig. 2 is a vertica sectional View of the guides of Fig. 1; Fig. 3 is a detail top plan View of the guide-base and an integral pillar, and Fig. 4 is a cross-sectional view on the line 4-4 in Fig. 3 looking in the direction of the arrows.

In thedrawings the reference numerals 1 and 2 represent two pairs of rolls mounted in suitable housings 3 to form successive passes for rolling metal shapes; the set marked 2 may represent a finishing pass, and the metal being rolled is generally designated by the numeral 4. The roll-passes are shown as arranged side by side or in axial alinement to illustrate the capability of the guide to loop or double the path of the metal hack on itself so that as the latter emerges from one pass it'may enter the next pass without bodily reversing its general motion between successive passes. The guide is formed with a rectangular cast metal base 5 which is bolted as at (3 to a suitable stand or support (not shown), and carries near one end a verical pillar 7 which is preferably, but not necessarily, integral therewith. The base is formed in its upper or outer face in line with the pillar 7 with alongitudinal guideway 8 in which the foot 9 of a second pillar 10 is adjustably mounted; the foot 9 is held in v adjusted position by bolts 11 passing through elongated bolt-holes 12 in the base-plate,

a which is channeled as at 13 on its under or inner side to receive the bolt-heads and hold them from turning when the retaining nuts '14 are applied. Each pillar carries a central integral post 15 which is screw-threaded at its upper end to receive a threaded cap 16, and a roller 17 of uniform diameter is revolubly mounted on each 'post between its pillar and cap; Ball bearings are provided etween the rollers and their pillars and caps as shown respectively at 18 and 19, and roller-bearings are provided between the rollers and their osts as shown at 20. Each cap 16 has an oil iiller passage 21 in extension of an oil channel 22 in its post.

The guide can be used for various rolled shapes, such for example as blooms, billets, ingots, round or other shaped bars or rods, slabs or flat strips. The width or space between the rollers is adjusted to accommodate different sizes of metal being rolled, and so that it is at least substantially equal to the thickness of the metal coming from the leader 7 pass 1 to the next or finishing pass 2; it is obvious that this adjustment can be obtained by making one or both of the rollers 17 adjust-able. The guide pass is of sufiicient .width to allow the moving body of metal to freely pass through with only such slight contact as may be necessary to control its line of motion; the rollers 17 are not mechanically operated and do no mechanical work on the metal in the nature either of transmitting motion to it for feeding it lengthwise or for canting or twisting it circumferentially, or of affecting its configuration .by compressing or reducing or deforming it. The guide forms a neutral transition or direction control pass, and consequently practically eliminates friction; guides which positively act upon the metal to reduce or deform it or feed it to the main rolls or circumferentially cant or twist it necessarily create friction which wears the guide members and unless the latter are frequently dressed or renewed V they scratch and deface the metal. As the pass between the rollers 17 forms a neutral direction-guide, it relieves the friction or affords a friction-relief guide, which reduces the wear on the rollers so that their life is prolonged and they do' not injure the metal,

and the metal coming from a roll-pass is presented to the next mill-operation without any structural change. The guide acts as a straightener for rolling metal when it is set at either the entrance side of a pass as shown at both passes 1 and 2, or when it is set at the exit side of a pass as shown at the pass 2;

when the guide pass conforms to the corresponding dimension of either a'plane ora grooved pass of either preceding or succeed ing rolls it straightens the metal being rolled without otherwise changing its contour or,

form. The guide can be disposed and used for both of the purposes stated with its rollers either vertical or horizontal; in the latter succeeding roll-passes arranged in difl'erent horizontal planes, as for example with a three-high mill it 100 s-the metal back on itself from either r0 l-pass' to the other.

- When the guide is set between two disalinedpasses it correspondingly changes the path of the metal between them, it being obvious that thereby" the metal can be acted on by the successive passes without bodily reversing it inits general line of motion. For these i laterally into it when they are horizontal,
