Articles, of which the following is a speciiication.

The brace irons are primarily designed for use in connection with the' wooden rch pieces of the running gear of a road ve 'cle, especially of road vehicles of light weight. These b-rcc'e irons ere usefulfor many purposes. Among these may be mentioned their combination with wooden perch pieces,

for the purpose of strengthening the latter.

My mode of making this breoing iron is new and useful end is unimproved mode over the modes of making similar analogous shapes of metal. T

The several features of m invention and the various advantages resu ting froin their use conjointlyor otherwise will be apparent from the following description and claims.-

In the accompanying drawings making a part of this application, and in which similar letters of reference indicate cerrespondin I parts,-l ligure l. is an end view of the meta blank out of which the brace iron is formed. Fig. 2 is a. view in perspective ofthis blank.

Fig. 3 is a view of the end of this metal blank,

as fornhed during the operation of the rocess of transforming this blank into the race iron, and showing in vertical transverse section the rolls for doing this work, the rolls being located in conjunction with the iron. Fig. 4 isa view in perspective of the metal blank shaped in the process illustrated in Fig. 3. Fig. 5 shows inelevation the end of the metal blank' whenshaped ac cording to the second operation of this rocess, and also, in section, the rolls emp eyed to effectuate this operation. Fig. 6 is aperspective view of the metal bank, of which-an end view is shown in the preceding figure. 7 shows in elevation the end of the metal blank when shaped according to the third 0 eration of this process, and, in section,

s owe the rolls employed to efiectuate this operation. Fig. 8 is a perspective view of Fig. 9 is en.

jected to a. fourth operation, and also shows .in section the rolls which accomplish the reduction of the metal to the shape shown this figure. This final operation completes the metal brace or brace ironas it is commonly termed. The correct shape of the end of the finished brace. is therefore shown in this fi ure. Fig. 10 is a view in perspec tive'ott e completed brace. Fig. 11- IS a view showing the manner in which the Wooden perch piece is to be pre ared to be in readiness for-combination Wit the brace iron. Fig. 12 shows in perspective the combination of the brace ironwith the wooden perch piece. Fi 13 shows a metal blank in the process 0 formation .into a brace iron.

I will now proceed to describe. my invention in detail.-- The coinpleted channel piece to wit: thebrace iron has a back A, sides 0, C, and flanges B,.B. Each side'C, on the edge opposite where it vjoins the back A, has one of these flanges B. The fiangesB, E

extend from the sides 0, 0, toward each other, and preferably the planes of the-sides of these flanges B, B are parallel to. the lane of the surface ofthe back A. The race .iron rney be'rnade of any suitable metal. "Iron is the preferred kind of metal.

blank Z is a flat sheet piece of metal of the requisite size.

This blank is now subjected to a top roll G, and a lower roll H having the side flanges I, I. By this operation, the blank assumes the shape-shown in Figs. 3'

and 4. The blank thus formed isnow subjected to the. action of a lower roll'K, having side fian es L, L, amidst the same time to the action cl an upper or top rollJ. The bot tom of the upper roll is concave in crosses tion substantially as shown; see the concave curve-5X of thisrolLFig. 5.. The sides J, J of this roll are inclined outwardly from the bottom to theoint where the flanges B, B

of the iron respectively come near to or against them. The bottom portion of the lower roll K is substantially or the same convexity as is the concavity of the upper roll J .see the curve KX of this roll.

indicated by the curve B. The sides C, (1,

are inclined upwardly and outwardly, and the flanges B, B, upwardly and inwardly, as represented in Figs. 7 and 8. The rolls keep the sides G, C, of the blank much inclined outwardly, and form the lower corners (l 0 of an obtuse angle shape. That is to say, these corners are notyet formed into sharp Here; the junctions between the sides and the back are not sharp angles but adual curves, and the back is curved up etween the sides. The blank thus formed is now subjected to a top roll M and to a lower roll P. The roll M has the inclined sides N and a concave bottom hm. The lower .roll P has the inclined side flanges Q, Q, and the tread of this roll-is convex as indicated by the curve PX. The inclina tions of the working sides N, N, ofthe roll M and the sides Q, Q, of the roll P are less than those of the rolls J and K aforesaid, that is to say, these sides of the rolls M and P are more vertical than those of the rolls J and K.

The blank resulting from the operation of iron is now in an unusually good form to re- ,ceive the final operation whereby it is bent to. its final, complete and perfect shape.

The iron is now subjected to the action of the rolls R and T. The upper roll it has a flat tread RX, and its sides S, S, are substan- T'he lower roll T is flat on thebottom tread TX, and sides or flanges V, V, of this roll are vertical. The efiect of these rolls is to accomplish in a very simple manner the shaping of the iron into the completed form. This completed form is illustrated in Figs. 9 and 10.

The object in h ring the two sets of rolls,

' namely: those shown in Fig. 5, and those 1 shown in Fig. 7, both similar except that the sides of the one in Fig. 5 lie more nearly hori .zontal than those of Fig. 7, is to enable heavy (thick) plate to be rolled Without breaking at the corners C 0 This gradual bending of the metal and its gradual assumption of a sharp angle at the bends which constitute the corners enables the heavy metal to be successfully bent atth'esehnes. When the metal of the blank is liht (thin), it can be bent without the aid of the rolls of Fig. 5.

4 In other-words, this step of the process can left before entering the rolls.

stance be dispensed with. In such a case, the metal blank formed between the rolls G, H, of Fi 3, can be next subjected to the rolls M, 1?, of Fig. and thereafter to the rolls R, T, of Fig. 9. This method of forming the brace iron enables it to be manufactured in a simple, ei'lective and economicalmanner. There fore the brace iron can be made of tougher and better iron than when cast of malleable iron. Other advantages of this process will be obvious and apparent. I

The rolls have been described where the bottom or backof the brace iron isunderneath, but the osition, of the rolls and the iron might be c anged. This is immaterial, so long as they all occupy the same position relatively to each other.

Each flange of the rolls may constitute an independent roll, but such division would be expensive, and not im rove the product, to wit: the iron brace. herefore such division i undesirable and de arts to this extent from the simplicity of t ese features of my invention.

In Fig. 13, I have illustrated the'four ste s aforedescribed of the rocess of making tile brace iron. The meta blank Z is seen at the Part 1 shows the result of the first set of rolls; part '2, of the second set of rolls; art 3 of the third selt1 of rolls, and part 4. ot the 'fourth step of ro s.

When the metal blank is a long one and the sets of rolls are successivly near each other, they will all actin close succession on the blanks illustrated in said figure.

In the opening portion of this specification, I have said that these brace irons are pri marily designed for use in connection with the wooden erch pieces of the running gear of a road ve' cle, but I wish it understood that I am aware that the brace iron is usefully ap ,licable in'many constructions other than ve icle perches, and I therefore claim my invention and its several features in their application for and in all such application. When combined with perch pieces E, channels F, are cut in sides of. these pieces, one channel at each side, and the brace is applied to the perch, each of the flanges B, B respectively entering the adjacent channel F, as illustrated 'in Fig. 12.

What I claim as new, and of my invention and desire to secure by Letters Patent, is

1. The herein described process, which consists in forming flanges upon the sides ofa rectangular metal blank, bending the stsntially vertical position, substantially as blllank aflter'saiii flsiinges have beeilfonned so described. 1: at it as inc ine si es, 11 War y curvin the bottom of the blank, aiid straightening HENRY HIGGIN 5 the bottom thereof, thereby 'brin 'ing said Attest:
