APPARATUS FOR THE MANUFACTURE OF FRAME-PLATES FOR ROLLING-STOCK.

SPECIFICATION forming part of Letters Patent No. 397,178, dated February. 5, 1889.

Application filed January 18, 1888.

To all whom it may concern:

Be it known that l, SAMSON FOX, a subject of the Queen of Great Britain and Ireland, residing at Harrogate, in the county of York,

invented new and useful. ln'lprovements in Machinery or Apparatus for the i\lanufacture of Frame-Plates for Rolling-Stock; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

In the specification of former Letters Patent granted to me under date the 11th day of facture of flanged frame-plates for locomotives and other rolling-stock, each made with flange or flanges in one piece of metal in the manner set forth in said specification, and in the specification of other Letters Patentbearing date the 3d day of August, 1886, No. 346,539, machinery or apparatus is described for the manufacture of said frame-plates.

According to a further invention described in the specification of an application for Letters Patent of even date herewith, Serial No. 261,165, I construct frameplates such as aforesaid in one piece of metal, not only with flange or flanges at one side, but also with a fillet or fillets around the openings for the therein and square corners at the ends of the bossments at and around such parts, and

required fillets and square corners.

Now my present invention has reference to machinery or apparatus for performing these operations, as I will proceed to describe with reference to the annexed five sheets of drawings.

Figure 1, Sheet 1, shows to line 1, in elevation, part of a hydraulic machine, with male die 0 in section on the line 2 2 of Fig. 3, and female die D in section on the line 3 3 of Fig. 4, corresponding to half the length of the frame-plate to be produced. Fig. 2, Sheet 2, shows, in elevation from the line 1, the other half of the machine. Fig. 3, Sheet 3, is a sectional plan of male die 0 O O on line 8 of Fig. 1. Fig. 4, Sheet 3, is a plan of female die and flooring E, with punches F, G, and H Serial No. 261,166. (No model.)

Fig. 8, Sheet 3, is a sectional elevation of female die D, flooring E, and punch F on line 11 of Fig. 4. Fig. 9, Sheet 3, is a sectional elevation of female die D, flooring E, and punch H on line 12 of Fig. 4, showing the recesses 6 in the flooring for admitting the bulged part of the plate surrounding said opening. Fig. 10, Sheet 3, is a sectional elevation of female die D, flooring E, and punch G on line 13 of Fig. 4. Fig. 11, Sheet 4, shows in sectional elevation part of a hydraulic machine with the dies for forming the fillets or the machine with the flanged filleted plate compressed between the dies. Fig. 13, Sheet 5, a face View of the male die 1. Fig. 14, Sheet 5, is a plan of half of the female die J with the inner floor and loose parts and the mandrels H and N in position. Sheet 5, is a side elevation of the mandrel M; and Fig. 16, Sheet5, is a cross-sectional elevation showing female die J on line 14 of Fig. 12, also loose parts L L around the axle-box Fig. '7, Sheet 3, is a sectional ele-' Fig. 15, 1

openings and loose parts in section running a the whole length of the straight side of the die and around the ends of a flanged filleted frame-plate being shown between dies I and J.

For the purpose of making in one piece of metal a frame plate with flange or flanges at one side to give the required strength and rigidity, and with a fillet or fillets at the contrary side around the openings for the axleboxes, according to my present invention, male and female dies of special construction are employed. They are such as to make the said fillets with square internal corners, as also to produce at the ends of the frameplates square external corners.

A is the head of the machine, and B is'the rising table or platform actuated by hydraulie or other suitable mechanism. To the head .A is fixed a compound male die, C C C which is of a form corresponding to the general configuration oi the intended frame-plate with its tlange or flanges, G (3 being parts attached to the principal part C for forming, in conjunctimi with the female die, the before-mentioned bulgings, which parts C are afterward, by suitable means, released from the main part olf the male die.

I) is a wide-niouthed l'eniale die or nnttrix, the walls oi. which are curved or 'roui'ided inside at the upper part, and upon which the roughly-shaped plate to be treated is placed while hot. This die has an internal eontiguration correspomling to the outline form required to be imparted to the frame-plate.

It will be understood, therefore, that the forms oi the male and female dies are subject to variation to suit the shape of frame-plate required.

The female die or mat rix, 'D is lixed to the rising table or 'ilatform l3.

E the 'flooroi this t'en'ialtii die. eesses opposite the projections 5 of the male die. By these project ions and the recesses (J the bulgings above referred to are formed upon the frame-plate. The floor E is securely lined to the table ll. 1 and G are punches, which, together with the corresponding openings, l5" and G, in the male die, form the :tlanges around the lightening holes in the frame-plate.

H is one oi a series of punches which, in conjunction with openings ii .in the male die, effect the tlanging and bulging around the openings in the frame-plate for the axleboxes. All these punches are placed loosely in openings in the floor E of the female die 1), and are rounded at their tops to enable them to turn the said flanges. Below their rounded parts, at and from line 7, they gradually diminish in width as they proceed downward, so as to be free within the newly-formed hanging, and on the recession of the table B from the male die can be easily removed previously to the flanged plate being taken out of the female die.

It will be understood that the machine comprises not only the parts shown in Fig. 1, but also those shown in Fig. 2.

Figs. 5, t3, and 7 show the part flavhich runs the whole length of the male die, and is titted thereto with a beveled joint and fixed with bolts and cotters, as in the case of the parts (1 and. and is released at the same time and in the same manner as those 1 )artsnamely, on the flanging operation being completed and removal of the aboveine'ntioned cotters to permit of contraction of the frame-plate due to cooling, Figs. 5, 6,

and 7 also show the flanged frame-plate X upon the male die C, and Figs. '8, 9, and 10 show it as it would be within the female die 1) before removal therefrom for the next op eration or trimming of the edges of the flanges previous to the formation of the ti (1 are re- I the metal of such parts during the lormarequired fillets or projections around the axlebox openings and square corners atthe ends.

The male and female dies and mandrels used for this purpose are shown in l igs. l l to 16, both inclusive. 1 is the, male die attached to the head A ot. the machine. .l' is the female die, with its cmnpontmt interior parts or floor K attached to the table 1-3 of the machine, and loose parts l) fitted to the said floor with beveled joints, (as in the case ofi the first-named male die (I (1 (1 Tliese parts L,being at the u 'iperside oi the part K, do not require bolts and eotters, but will rest thereon.

The frameplate X, in the form in which it leaves the dies (3, C, C', and D, is reheated, and then is placed flange downwanl in the female die .I', as shown in Fig. ll. Mandrels M (shown in side view in Fig. 15) are placed within the buckled parts of the axle-box openings, and mandrels N areplaced between the buckled parts at the ends oi? the plate and the inner end of the female die J to back up tion of the nojeeting [diets and square corners. The whole are then caused to advance against the male die T, the face view of which is shown in Fig. 2.3. O O are recesses therein for :t'orming the projecting fillets. The surfaces of these recesses press upon the mandrels M and cause them to descend into the axle-box recesses, pressing at the same time upon the buckled parts of the frame-plate, and causing the metal thereof to enter or flow into parts of the said recesses and to form the required fillets with square internal corners. The plain surfaces of the male die at the same time press against the mandrels N, which together term the end' bucklings into square-eornered flanges. The completion of this operation illustrated in Fig. 12, the frame-plate X being shown still between the dies.

The loose parts L l. are arranged as shown to allowof contraction of the frame-plate during cooling, and as it is being forced from the female die J by the action of sundry small rams of the machine or by other means. These parts L L, as clearly shown in Fig. 14, when they are in the position there shown, are not in contact at their ends, as shown by the openings, being held outward by the wedge mechanism shown, for instance, in detail in Fig. 16. Now, the plate having been compressed, shown in the said drawings, Fig; 16 and in Fig. 12, the bolts and cotters being released which maintain the parts L and't-he exterior n-essing parts in their relation with the press, as shown in Figs. 5 and 7, by gradually withdrawing the lower plate, B, it follows that these angular pieces will follow down with the metal and permit of the shrinkage of the metal. It is important that this withdrawal of the press B shall be gradual, allowing for the shrinkage of the metal, for if it were suddenly and rapidly don e there would be a tendency for the metal to warp and shrink out of shape.

I do not in this application claim the proccss therein described, having made a separate application therefor on the 29th day of November, 1888, Serial No. 291,470.

Having described and ascertained the nature of my said invention and in what manner the same is to be carried into practical eifect, I hereby declare that what I claim is as follows:
