To all 207107712 may concern-5 Beit known that LWVILLIAM J. BRADLEY, a citizen of the-United States,residing at Troy, in the county of Rensselaerand State of New York, have invent'ed certain new and useful Improvements in Ron (lonstruc tions for Rolling-Mill's, of which thefollowing is a specification;

This invention relates'to anove'l roll construction for rolling mill-operatio11s,-and having special utility as one of the units of a set of rolls for making a specialdesign of railway tie plate.

Oneof the leadingobjects of-the invention is to provide a sectional roll construction comprising a plurality of readily removable and replaceableunits, thus reducingthe expense of breakagestoa minimum. A further object is to provide a sectional r'oll member having an adjustable"characteristic in the sense of being readily" and inexpensivelychanged to vary the distance between the inside rail flange bearing shoulders-bf" a railway tie plate.

With these and other objects in view which will be appreciated by those familiar with this art, the invention consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated, and claimed.

The essential features, of the invention, involved in the sectional and adjustable feature of the improved roll member are susceptible of structural change within the scope of the appended claim without departing from the spirit and purposes of the invention, but a preferred and practical embodiment thereof is shown in the accompanying drawings, in which:-

Figure 1 is an elevation of a set of rolls in a rolling mill embodying the improved sectional roll construction contemplated by the present invention.

Fig. 2 is an enlarged view of the improved sectional roll member illustrating the same as forming the leader pass of the set of rolls for making the special design of tie plate referred to.

Fig. 3 is a detail view in perspective of the special design of tie plate produced by the passes of the rolls illustrated in Fig. 1.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

7 Since the improved-sectional rollmember possesses special utility aso'ne 'of the-units ofa "set of; "rolls for making =a+railway tie plate-having certain structural character-istics-reference will first *be in a'deto the latter. A tie plate of this character is shown in Fig; 3 of the drawings, and inclu'des a rectangular body plate '1 provided at the 'upper side thereof with a fiat rail seating floor '2. At the opposite anarginal edge portions of its floor-,1 the body-'1' has "formed thereon the raised rib portions I and 4 M respectively which are l'OllIlClEd-tOIl. their upper-surfaces, as ata5, andpresentat their inner edgesthe vertically disposed inside rail' fiangebearing shoulders 6; In additionthereto, the=said tie plate embodies other-,1 features of 'construction which are developed the final pass of the rolls ---a ccording to the process disclosed in my parentapplication Serial Nc.-15,ta0, fi1ed March '2O,-I91*5.

As already indicated, the improved sectional roll member, the'uglr susceptible of more general application, is specially adapted for use as one of the units of a set of rolls for making the special design of tie plate described, and in the drawings the in vention is shown as applied to a set of mill rolls generally designated by the reference letters A, B and C. These rolls provide a series of roll passes designated respectively I, II, III, IV, and V in which are developed the tie plate or metal shape shown in Fig. 3 of the drawings. The passes I and II give to the bar its approximately primary form and size, and the pass V is the final pass of the series and includes a roll formation which gives finished form to the Various structural features of the tie plate. At the same time, the intermediate passes III and IV carry out a stage of the operation which is rendered practical and effective by the novel construction of roll member constituting the present invention.

Referring now to the novel roll member claimed herein, it is to be noted that the same provides for the final shaping and spacing of the inside flat bearing shoulders 6 of the tie plate, and this operation is accomplished in passes III and IV of the rolls. With respect to pass III, it will be noted from Fig. 1 of the drawings that this pass is provided between roll members, one of which has a reducing collar 7 formed with shallow peripheral grooves 8, and the other of which roll members includes rounded former rings 9, and intermediate reducing rings 10 and 11 which further develop the flat floor 2 of the bar blank, and one of which rings, designated by the reference number 11 may be termed a rib-gaging die-ring. This latter ring is readily removable and replaceable and is employed in varying sizes according to the required distance between the inside bearing shoulders 6, which distance is determined by the width of the rail base flange.

A further reduction and shaping to determine the distance between the inside shoulders 6 and the final working out of the projecting ribs from the base or under side of the blank areeffected in pass IV. This pass is provided between roll members, one of which substantially consists of a plain reducingcollar 12 which flattens the base. The other roll member of the pass'IV comprises rounded marginal former rings 13, and intermediate reducing rings lei and 15, the latter like the ring 11 being a rib-gaging diering and interchangeable with other sizes.

Thus. it will be seen that the sectional roll members for passes III and IV are substantially alike with respect to the adjustment feature of being adaptable to the required distance between the inside bearing shoulders 6 of the tie plate, and also with struction may be resorted to within the scope of. the appended claim.

I claim:

A roll for rolling shapes with spaced inside shoulders the same including a pair of opposite marginal die-rings provided with shoulder-sha1i ing die surfaces v and an in termediate ring interposed between the mar ginal rings and provided with a fiat peripheral die surface and with fiat shoulder-shap ing die-edges, the latter overhanging the die surfaces of the marginal rings, the said in termediate ring being interchangeable with similar rings of different widths.

In testimony whereof'i hereunto affix my signature in the presence of two witnesses.
