To a/ZZ whom t may concern:

Be it known that we, WILLIAM S. GILLEN,

of Allegheny, and WILLIAM G. ANDERSON,4

of Emsworth, in the county of Allegheny and State of Pennsylvania, have made certain new and4 useful Improvements in Rolling- Presses, of which the following is a specification.

Our invention relates to meansI for manu-A` facturing metal beams, sills, holsters, and similar structures, and particularly to the manufacture of such of those articles referred to as vary in width and which are provided means for this purpose have been very cumbersome and expensive in construction and l slow and tedious in operation.

The objects of our invention are to simplify such means, to produce a better article, and

togreatly reduce the time and expense ordinarily expended in such operations. i

To these ends the present invention consists generally of a new and improved rollerpress or Hanging-machine, of new forms and arrangement of a roller-die and slide-die, and in the construction,arrangement, and combination of parts of the mechanisms referred to, all as hereinafter A fully described and claimed. V

In the accompanying drawings, which illustrate forms and applications'V of our invention, Figure lis a view in side elevation of our roller-press; Fig. 2, a plan view; Fig. 3, an end elevation, partly in section, taken on about line 3 3 of Fig. l; Fig. 4, a perspective resenting a finished product; Fig. 6, an end view of a detail consisting of a modified form of dies, and Fig. 7 a perspective view of blank from which "the finished product is formed.

Inlthe drawings we have shown an apparatus particularly adapted for making side sills or beams used inthe construction of railwaycars, and our description is restricted to such apparatus and articles; but it should be understood that our invention is not limited to the manufacture of such products alone, as it comprises means for forming a flange or edge.

i flanges on a piece or sheet of metal of varying width or having an irregular outline.

A preferred form of metal side sills or beams used in steel-car construction is usually about forty feet in length and is similar to the form shown by Fig. 5 of the drawings. These sills are formed of a single piece of metal and have a central swelled or bellied portion, tapering end portions, and longitudinal side .flanges formed on opposite sides, one flange following the straight edge or side and the other flange theirregular outline of` the opposite edge or side. As illustrated, A represents the swelled orbellied portion of the sill, and n.3 a Harige following the straight side or For the purpose of calling attention to the irregular flanged outline of one side or edge of the sill we have in the drawings somewhat exaggerated the lines of departure from one4 irregular flanged portion to another and have designatedV those portions by the letters a, a', and. A2. In the finished article as made by us the angle effect shown in Fig. 5 is not produced, for the portions a, ct', and A2 gradually merge one into another and form a continuous curved flange on the irregular side or edge. As shown, central flange a, as well as` end flanges A2, are substantially parallel with the straight side or edge of the sill and its flange a3. The central flange c being connected with end flanges A2 by intermediate flanges a produces a continuous flange following the irregular contour of the irregular side or edge of the sill.l In some instances it may be desirable to form the sills with swelled flanged portions on both sides thereof, in which case it would only be necessar-y to modify the die-surfaces accordingly Without departing from our invention.

In the construction shown in Figs. l, 2, and 3 we employ a sliding die-section B and a rolling die-section O, the latter operating after the manner of a former and` may for such reason'be termed a rolling former. The ytwo die-sections are mounted on a suitable frame, the section B resting uponrolls D and being provided on its under side with a rack E, meshed by a pinion F on a shaft G which may be given motion in any suitable manner.

By the described construction the slide-plate B may be moved back and forth beneath the rolling former C. This rolling former C has its shaft H journaled in suitable supports I on the frame and is provided with a gearring J, meshing with a rack K on the slideplate, so the two parts may move in unison. As shown, the slide-plate is reciprocated, and thereby imparts motion to the rolling former. Manifeslly, however, the rolling former may be turned to operate the slide-plate without departing from any of the principles of our invention. As shown, we provide the slideplate with the toothed racks E at both edges and the former C with the gear-rings .l at both sides to mesh with the said racks, this being preferred, because it avoids any twisting strain upon the machine; but it is obvious that one of the racks and rings might be omitted, if desired. In the operation of this construction the plate is reciprocated beneath the rolling former. lt may be desired, however, to arrange both the die-sections to revolve, as shown in Fig. 6, wherein the male die-section L is geared at L with the female die M, the die-surfaces being formed 'substantially in accordance with the construction shown in Figs. 3 and 4 and which we will now describe.

. As shown in Figs. 3 and 4, and as preferred, the slide B is the male die-section and the rolling former C is the female die-section. To this end the section B is provided with die-surface B', which is provided at its middle with the laterally-projecting portion B2 and has the inclined edges B3, uniting said laterally-projecting portion with the end portions B4 of the die-surface B'. This die-surface B is of a length equal to or exceeding the length of the Stringer to be produced and coperates with the rolling former C to press a fiat blank plate by a rolling action into the form shownin Fig. 5. For some purposes it is preferable to form the die-surface B slightly convex or rounded instead of having a plain fiat surface. The rolling former C, as shown, has its die-surface provided With an irregular-shaped groove C of varying Width, the widest portion O2 of which corresponds to the laterally-projecting portion B2 of the surface B of the other die. It is further provided with a narrow portion C4, Which portion is connected with the Widest portion()2 by intermediate portions C3. Portion C4 and portions 03 respectively correspond With the portions B4 and B3 of the die-surface B. The outer edges of the Walls of the groove C are beveled, as shown by C5, for the purpose of gradually bending and forcing the edges of the metal plate down upon the other die. Groove C may be made of varying depth to coperate with the convex of curved die-surface B of the other die When it is desirable to have said latter surface of this form.

While we have shown the roller-former C our invention is not limited to this formthat is to say, the roller-former may be made in the form of a sector or other curved body suitable for performing the Work, and it is to be understood that the term roller-die embraces the forms referred to.

The two die-sections are so geared together or otherwise soconnected that their dies will be in complementary correlation-that is, so that the Wide and narrow parts of the male die will fit into the corresponding Wide and narrow parts of the female die and Will thus always be in such relative position as to engage the beam and to follow exactly throughout the contour of the sill or beam, which is placed, preferably, upon the male die.

If desirable to punch holes through the sill for rivets, bolts, and the like, the rollerformer may be provided with punches N and the surface B with sockets O to receive said punches, thus enabling the sheet or piece of metal to be both flanged and punched at a single operation.

Attention is called to the fact that We provide a roller-former whose die-surface is adapted to operate upon a sheet or piece of varying width and which in conjunction with another die is capable of forming flanges on the said irregular piece of metal. We are thus enabled to produce at a single continuous operation of the machine a sill or beam having a central swelled portion, a flanged .straight side or edge, and a fianged irregular side or edge. y

While We have confined the illustration of our invention to the manufacture of sills or beams having what might be termed lateral offsets, our invention is not limited to the manufacture of such structures, but includes means for forming a flange or flanges on the side edges of a piece or sheet of metal of varying Width. Our invention further contemplates the formation of flanges on both of the longitudinal sides or edges of the metal or upon the irregular side or edge only.

Manifes'tly the invention Will be useful and applicable to structural and naval architectural Work as well as for car-buildin g, and it may be desirable in some instances'to provide lateral projections on both sides of a beam, so as to make a double arch, as it were, and this may be accomplished by duplicating the lateral projections on the die-sections in order to provide for pressing the flange on the lateral projections of both. sides of a beam or plate, as will be understood from the drawings and preceding description.

By altering the sizeoflthe die-surfaces we will of course be able to produce sills, beams, &c., of any desired dimensions, and such changes will come Within the scope of our invention.
