Application filed November 22, 1922, Serial No. 602,535.

To all whom it may concern:

Be it known that 1, ROBERT E. WEAVER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Iteenforcing Members, of which the following is a specification.

My invention relates to metal reenforcing, stiffening, members for use generally, but more especially as end-stiileners, sidestakes and diagonal braces for freight cars.

One of my objects is to provide a construction of reenforcement whichshall possess the maximum strength for the amount of metal used and which shall possess a high degree of stiffness. Another object is to provide a construction of member of the character stated which may be constructed from commercial metal channels; and other objects as will be manifest from the following description.

Referring to the accompanying draw ings:-

Figure 1 is a view in vertical elevation of one end of a freight car employing as elements thereof members constructed in accordance with my invention, the section being taken lengthwise of the car on the line 1 of Figure -2 and viewed in the direction of the arrow. Figure 2 is a broken pla n section of the construction shown in Fig. 1, the section being taken on the line 2 of Fig. 1 and viewed in the direction of the arrow. Figure 3 is a perspective view of an end of the reenforcing member showing the b'eveling of the ends of the flanges thereof when this member is provided for use in connection with a pressed steel connection plate at the corner of the car.

Figure e is a similar view of the TGBIlfOI'C'.

ing member in final form and the pressed plate referred to, showing these parts assembled. Figure 5 is a broken plan view of one end of a reenforcing member constructed in accordance-with my invention and of a form suitable where it is desired that the reenforcing member be provided with angulariy extending portions at its ends, as for example, to overlap the sides of the car where the reenforcing member is applied across the end of the latter. Figure 6 is a view in elevation of the member of Fi 5; Figs. 5 and '6 showing a construction of member in which the flanges at the upper and lower edges of the member are eliminated at the ends thereof. Figure 7 is a view like Fig. 5, of another form of member suitable for accomplishing the purposes of the construction of Figs. 5 and 6. Figure 8 is a view like Fig. 6, of the construction shown in Fig. 7. lhe construction of the foregoing figures are all shown formed from connnercial channels. Figure 9 is a cross sectional view of a reenforcing mem ber constructed in accordance with my invention from metal of uniform thickness, as in the case of forming the reenforcing member direct from a sheet of metal, as distinguished from forming it from a commercial channel; and Figure 10, a perspective view of one end of a reenforcing member constructed in accordance with my in vention from metal of uniform thickness and presenting angularly disposed plate portions at its ends for accomplishing the purpose of the construction shown in Figures 5 and 6.

Referring to Figures 1 and 2 wherein I have shown one form of my improved reenforcing, stiffening, member as applied to a variety of positions and for a number of different purposes, to a freight car, 11 represents one of the similar end walls of the car to which reenforcing members in accordance with my invention and represented at 12 are a plied to form end stiffeners. The side wals of the car are represented at 13, these being shown as provided with diagonal braces 1 1 formed of my improved rcenforeing members, the drawings also showing my improved stiffening member as applied to a side wall of the car in upright position to present a stake pocket, this member being represented at 15.

The particular form of reenforcing, stiffening, member shown at 12, 14 and 15 is constructed from a commercial channel, and involves the rolling of the channel into the cross sectional shape sh' own whereby, in addition to the flanges 16 and 17 provided at the longitudinally extending edge portions of the channel, the member is caused to present midway between the edges just referred to, webs 1-8 and 19, which extend in the same general direction as the flanges 16 and 17 and substantially paralleltherewith, the outer edges of the webs 18 and 19 being connected together by a substantially fiat wall, as shown. Thus deforming the channel causes it to present two web portions 20 and 21, each of vided with two flanges at its opposite edges, as above referred to. The reenforcing, stiffening, members are applied to the sides of the car to bear at their web portions 20 and 21 against these walls, in which position they are rigidly secured as by rows of rivets, as shown.

The reenforcing and stiffening member of Figs. 3 and 4 is of a form highly desirable where it is to be associated at its ends with angular plate members and where it is desired that these angular plate members overlap the walls of the car extending at angles to the wall thereof against which the reenforcing member is applied. Such an angular plate is represented at 22, and the reenforcing and stiffening member referred to, at 23. The member is of the same construction asthe members 12 except that the ends of the member 23 are deflected outwardly to provide recesses 24 at the rear sides of the ends of the member 23 into which the adjacent end portions of the plates 22 extend, these parts being connected together as by the rivets 25. The member 23 is deflected, as stated, to produce recesses of a depth substantially equal to the thickness of the plates 22in order that the rear faces of the plates 22 shall extend flush with the rear surfaces of the portions of the members 23 intermediate its deflected ends. The flanges of the member 23 at the extremities which is prothereof are preferably beveled, as indicated.

As an example of the use of the construction shown in Fig.4, it may be stated that it may be used at the same places on the car as those occupied by the member 12 in Fig. 1, in which case the rearwardly extending portions 26 of the angle-plates 22 would overlap the sides of the car to which they may be secured, as by rivets secured in the openings 27 in the plate portions 26.

Figs. 5 to 8 inclusive illustrate constructions of the reenforcing, stiffening, member which may be formed from commercial rolledchannels and which, as integral parts thereof, provide rearwardly extending sections serving the same purpose as the porti ons 26 of the angle plates 22 of Fig. at. According to the showing in Figs. 5 and 6, the upper and lower flanges 16 and 17 at both ends of the member are cut away at right angles to the member,'as represented at 16 and 17 and the corrugation of which the webs 19 and 20 are parts, is rolled out at both ends of the member along inclined lines as shown at 27 of one end of the member. The portions of the member beyond the junctures of the corrugations with the web portions, is of flat form, these, portions being bent rearwardly to present rearwardly extending plate portions, the said portion at one end of the memberbeing represented at 28 and being provided with rivet receiving holes as explained of the portion 26 of the plate 22.

The construction shown in Figures T and 8 is the same as that shown in Figs. 5 and 6 except that the flanges l6 and 17, instead of being severed along lines extending at right angles to the member, are severed along diagonal lines 29, and the corrugation of which the webs l9 and 20 are parts instead of being rolled into the shape as shown and described in the constructions shown in Figs. 5 and (l, is rolled out into the shape shown in Figs. 7 and 3 wherein the corrugation merges into the rearwardly extending plate portions 3) of the member.

If desired, the reenforcing. still'cning, member may be formed from a sheet of metal of uniform thickness bent into the di sired cross sectional form, as distinguished from manufacturing it from a commercial rolled channel, and when so constructed,

would preferably present: the cross sectional shape as shown in Fig.

The forming of the member from a sheet, as states, lends itself to the production of reenforcing, stiffening members of the forms as those slown in the preceding figures and for the purposes above stated. here, however, the ends of the members are to be so formed that they will present, as integral parts thereof, angularly disposed plate sections corresponding with the plate sections 28 and 30 of Figs. 5 and 7, respectively, the upper and lower flanges of the member and represented at 31 and 32, need not he cut. away, as explained of the constructions shown in Figs. 5 to S inclusive, but may be flattened as shown in Fig. 10 to extend in the same plane as the web portion of the member, the centrally disposed corrugation of the member likewise being lattcned, the fi t-tening shown being along line corre sponding with the line 27 of 5, but if desired, the deforming of this corrugation may be as shown in Fig. 7. The deforming of the corrugation referred to and the bonding down of the flanges 31 and 32 as stated, causes the rearwardly extending portions of the member, the said portion at one end of the member being represented at 100, to be of relatively great height; as compared with the height of the body of the member, as shown, which is an advantage in some cases, it being understood that if desired, the flanges 31 and 32 may be cut away entirely at the ends of the member as shown and explained of the constructions in Figures 5 to 8 inclusive, or onlv part way cut away.

It will be understood from the foregoing description that a reenforcing, stiffening, member of the cross sectional shape shown presents a high degree of strength and stiff ness compared with the amount of metal used. Furthermore, it may be readily produced from commercial rolled channels, and

lIiO

-when produced in either of the ways described, may be caused to lend itself to ready application to different situations and at different places, particularly in a car where the use of members of this general character is desired.

While I have illustrated and described certain particular constructions constituting embodiments of my invention and have described these various constructions as produced in certain ways, I do not wish to be understood as intending to limit my invention thereto, as the invention may be embodied in other forms and the structures produced in a manner otherwise than as described.

I claim:

1. In combination with a car wall to be stiffened, stiffening member consisting of a channel comprising substantially parallel web portions at which said member seats against said wall, the flanges of the channel being located along the outer lengthwiseextending edges of said portions substantially in parallelism and generally in the same direction outwardly from said wall, the channel intermediate said. web portions having rolled webs extending substantially the length of the stiffening member and outwardly of the web portions, the webs being united at their outer edges by a substantially flat wall, and means engaging said wall and web portions to hold said stiffening member in place on said wall.

2. In combination with a car wall to be stiffened, a stiffening member consisting of a channel comprising substantially parallel web portions at which said member seats against said wall, the flanges of the channel being located along the outer lengthwiseextending edges of said portions substantially in parallelism and generally in the same direction outwardly from said wall, the channel intermediate said web portions having rolled webs extending substantially the length of the stiffening member and out wardly of the web portions, the webs being united at their outer edges, a plate-like por tion at each end of the stiffening member, and an angularly extending portion projecting from each of the last mentioned portions and fastened to the wall.

8. In combination with a car wall to be stiffened, a stiffening member consisting of a channel comprising substantially parallel web portions at which said member seats against said wall, the flanges of the channel being located along the outer lengthwiseextending edges of said portions substantially in parallelism and generally in the same direction outwardly from said wall, the channel intermediate said web portions having rolled webs extending substantially the length of the stiffening member and outwardly of the web portions, the webs being united at their outer edges, the webs being united by angularly disposed portions at their end edges, a plate-like port-ion at each end of the stiffening member beyond said end ed es, and an angularly extending portion projecting from each of the last mentioned portions and fastened to the wall.

4. In the art of manufacturing reenforcing, stiffening, members, the improvement which consists in forming the member to present substantially parallel web portions, each provided along its oppositelengthwiseextending edges with webs and flanges extending therefrom generally in the same direction, with the webs of the inner adjacent edges of the web portions united at their outer edges, and thereafter cutting away the end portions of the flanges at the outer edges of said web portions, rolling the ends of the corrugations formed by the upright webs at the inner edges of the wall.- contacting web portions to cause the ends of the member to be of plate-like form, and bending the extremities of the deformed member to extend at an angle to the body portion of the member.

ROBERT E. WEAVER.
