ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 355,390, dated January 4, 1887.

Application filed March l5, 1886.

To all whom it may concern:

Be it known that I, FRED H. DANInLs, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful lImprovements in Rolling-Mills, of which the following, together with the accom panying drawings, is a specification sulliciently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

This invention relates te the construction ol' the housings by which the roll-journals are supported and to the manner of connecting the driving-shafts and roll-shafts, the objects of my invention being, first, to provide a mechanism which will permit ready and convenient access to the rolls and guides in a continuons rolling-mill, and thereby to greatly facilitate the adjustment and removal of said rolls and guides; second, to provide a housing for continuous rolling-mills with a hinged or movable cap or top piece that can be conveniently raised to permit taking out and replacing the rolls, as required; third, to provide ahousing for continuous rolling-mills in which the upright at the front end is adapted to swing .outward or is removable 'from the front of the rolls, so as to permit of the rolls being con- 3o Veniently removed from the rear portion of the housing or from their shafts fourth, to provide a peculiar connection or coupling for conveying the driving-power from the operating shafts to, the roll-shafts in a rollingmill.

These objects I attainby vmechanistic the nature, construction, and operation of which .is herein explained, the particular subject-mat taierdclaimed vbeing hereinafter definitely speci- In the drawings, Figurel is a plan view of a rolling-mill housing illustrating iny invention. Fig. 2 is a front view of similar housings.

Fig. 2T is a vertical section through the front roll-bearings at line w w, Figs. l and 3. Fig.

2x is a vertical section at line a: x, Figs. 1 and '3. Fig. 3 is a vertical section of the housing and bearings longitudinally With roll-shaft. Fig. 4 is a similar section of the housing-frame, with the rolls and journal-bearings removed.

5ofFig. 5 is a modification of Fig. 4, showing the cap-piece removableinstead of hinged to swing upward. Fig. 6 is a longitudinal section Serin] No. 195.340. (No model.)

through the shaft-coupling devices in the direction of liney y. Fig. 7 is a transverse section of the same at line z, Fig. 6, and Fig. Sis

sets of rolls, of which any desired number of 6 pairs may be employed in the mill.

As the construction of the housings and coupling devices are similar for each pair-of rolls, description and illustration'of a single one will herein be sufficient for giving a clear understanding of the nature of my invention.

C indicates my improved housing, which consists of a suitable base, c', having uprights c, that serve as guides and supports for the journal-boxes D D and as supports for thel top or cap plate, F, which latter is secured thereto by the boltsj'f, or in other suit-able efficient manner.

The forward portion of the cap -plate F, which extendsoverthe rolls, isj ointed orhin ged to the rear portion in such manner that it can be removed or swung'npward from its 'normal position in a ready and convenient manner, as indicated by dotted lines in Fig. 4, to give access to the parts beneath. The hinge or joint is preferably arranged as shown at H, the bolts f' being forward ofthe hinging.

The forward end of the swinging cap F is provided with dependent guides or lugs c,for confining the journal-box of the top-roll shaft, and the'base C is fitted with upward projections or guides, c, 'for confining the journal-box of the lower roll.

The forward end of the movable cap F is secured to the base c by a removable or hinged standard or bolt, I, that is preferably hinged to the forward end of the base in a Vmanner similar. to that shown, so that it can be swung downward, as indicated in Fig. 4.. The upper end o f the standard is fitted with a collar or shoulder, as i', and with a nut, I', and the forward end of the swinging cap F is made with a recess to receive the neck of the bolt I, and with jaws or surfaceswhich can be clamped between said nut and shoulder, so that when the parts are in normal position (see Figs. 1, 2. and 3) and the nut tightened, the cap-plate F and standard I will form arigid support and housing for the iront journals and journalboxes.

The f ront j onrn al-boxes are shown herein as provided with ears d d', or suitable connections, by which the inner half of each of the boxes 1s attached to the standard I, so that Aswveling the box tothe pressure-bolt, or bya A Cl ' subject to vibration.

pin and slot through the dependent guide c, as indicated in Fig. 5, the pins m being fixed in the sides of the bearing-cap and projecting into or through the slots.

vly making the housings with the removable or hinged cap-piece F and theswinging standard I, as shown and described, the front of the mill can be quickly and conveniently thrown open in a complete manner, and free access thereby allowed to the rolls and guides to facilitate their adjustment, removal, or repair, or for removing blocked or tangled rods from any part of the mill. Vhen the front of the housing is opened, as described, the rolls can be swung out horizontally by means of a suitable crane or lifting mechanism.

As a modilication, in lieu of making the cap F- with a hinge-joint, it may in some instances be made simply removable, the standard-bar I being employed for retaining its forward end and the bolts ff for retaining its rear end, as in Fig. 5. Said standard may also be made so as to lock between jaws c of the front of the base, in lieu of having a pivot or hinge pin. The standard I may also in some cases be of cast-iron, if desired, properly formed to give the requisite strength. I prefer, however, the bolt-formed standard, as shown. The lower part of the standard lis preferably bifurcated or extending laterally where it hinges to the base, inthe manner indicated,(seeFig. 2;) but, if desired, said standard may be made as a straight bolt or bar. The bifurcated form,how gives the more rigid support and is less In place of the rigid collar or shoulder i, a nut fitted ou a screw formed on the standard may be employed, if desired.

Another feature of my invention consists in the peculiar device for and manner of connecting or coupling the roll-axles a to their operatingshaftsB,which coupling is as follows: A transverse recess, groove, or notch, n, is formed across each of the adjacent ends on the shafts B and roll-axles o, and a iat plate of cast-iron, P, is inserted with; its ends in said notches, as indicated in Fl` 3 and 8, which plate P forms the drivingconnection. The ends of the plate are fitted comparatively close in the notches, but are sailiciently loose to allow slight play to iiicconnnodate any irregularity in the runningA or align.- ment of the shafts and roll-axles. "'iilie plate l3 is retained in position by means nl' a small wire, S, bound around the ends of he parts, as indicated. A slight annular groave or' depression around the shaftprevent-v the wire from slipping out of place.

The central portion ot' the coupling-plate I is preferably reduced by a transvcne groove or depression, r, so that while the ids properly till thenotches n there will be an intermediate portion of weaker structuru4 between the ends. This' weakest central pf; rt ol' the plate is given sulicient strength to drive the rolls under normal conditions of vork, but not enough to transmit a great excess at' power. Thus, if the rolls become blocked by tangling of the rod or other abnormal. condi. ions, the plate F becomes broken across its center r and the coupling thereby released, and the motion of the rolls at the point where the dil'lieulty occurs is thus immediately stopped, and continuation or increase of the troubleis fibviated. The coupling-plates are cheap, earily made and inserted, and form a very desir tble i'orm of automatic relief coupling for th( purpose specied.

The driving-shaft B' and gears and the guides intermediate between the rol s may be constructed and arranged in any slitabie or well-known manner, or substantiallt as heretofore employed in Icontinuous rol rolling mills. Such parts are therefore noi shown in the present specification, as any onfconversant with this class ofmachines will fully understand their construction and arr:v`l agement.
