Figures 6 and 7 are horizontal cross sections of modi?cations illustrated in Figures 1 and 2, Fig. 8 is a fragmentary perspective view show ing one manner of producing the article illus trated in Figure 5. Figure 9 is a fragmentary perspective view showing another manner of forming the stiffen ing member to receive the screen material to produce an article corresponding to that shown In this way, the heat is absorbed from the weld body by the flanges I2 and dis sipated by these, so that a minimum amount of heat is transmitted or accumulated in the ex treme edge portion of the open-mesh material I l . By the assembling method described, using two separate strips to form the ?anges I2, the welding of the open-mesh or sheet metal material effects also the securement of the two ?anges together, so that a complete angle is produced and the advantages utilized in the stiffening of the unit produced. In Figure 3, the angle l0’ may be produced of two straps of metal struck together at the proper angle as illustrated, while the body or the screen extends inwardly from the angle, but with an edge portion which projects out in Figure 2. wardly at the convex angle formed by the two Figure 10 is a similar view showing another ?anges.

There is illustrated in Figure 1 a portion of a unit structural member suitable for various uses, and which may represent one corner of a rectangular frame, consisting of a suitable num understood hereinafter. In this particular in stance, channel portions of the angles are dis posed at the outer sides of the frame, and the screen material is engaged With the angles or solid members at the outer sides of the angles formed by the junction of the two ?anges l2 and the concrete may be introduced until its top surface lies flush with the upper edges of the angles H5, as will be appreciated. The slabs cast in this manner will thus be reinforced by the open mesh material, while its edge portions are protected against chipping by the edge portions of of the angles, and the screen material being ex tended in a plane which approximately bisects ; the ?anges [2. The units formed as in Figure 1, and other the angles at the junction of the ?anges I2. modi?cations to be indicated herein may also be set up on edge and connected to other elements The screen material may be extended from the inner side of this angle, substantially in the rela tion shown in Figure 3, if preferred, and may extend in various other directions, as shown in the succeeding views, Figures 4, 5, '7 and following. The angle l5 may be formed in various ways, being adapted to be assembled from two ?at strips or ribbons of materials brought together at the proper angle as shown in Figures 2 and 3, and following, where it may be a stock L-angle rolled in one piece and, pierced, out, or other— wise formed at the angle therein to receive the open=mesh or sheet material, as will be described more in, detail hereinafter. In producing the article of Figures 1 and 2, the respective strips intended to form the. ?anges l2, are brought into position as shown in Figure 2, after insertion of an edge portion of‘ the screen material ll there between, so that a small portion of the edge of‘ to be supported as a fence or other enclosure. In Figure 4, the manner of attaching the screen with relation to the ?anges of an angle is illus trated, the screen material I! being laid against the inner side of one of the ?anges with its ?rst portions projected outwardly past the abutting edge of the opposite ?ange, while a weld I 5 is ,- built up at one side of the angle around the projected edge portion of the screen material II. In Figure 5 the screen material is shown in the same plane with respect to the angle, as in Fig ure 4, but instead of being laid against the inner side of the bottom ?ange lZ-A, and extended away from the angle beside that ?ange, the screen material is located outwardly of the an gle, with its edge portion inserted inwardly be tween the flange [2’ and the ?ange I'2—-A, the ' weld It being then built up at the inner-side of 5 2,412,618 the angle. In these last described two forms, the angle di?ers from the arrangement of Figures 2 and 3 in that in Figures 2 and 3 the ?anges of strip 34' set at the proper angle to a straight strip-34a, so that the salients of the corrugations abut said opposed straight strip. The corruga tions of the strip may occur throughout their the angles extend a common distance from the vertex of the angles, while in Figures 4 and 5, the upper ?ange l2’ shown is butted against the in ner side of the ?ange l2-A, or at least against the screen material inserted between the two. The bene?cial result in the transmission or con duction of heat from the weld to the ?anges, and its rapid dissipation, are gained in the last de scribed forms of the article in the same manner as in the ?rst two. lengths or at intervals, as desired. In Figure 13, there is shown the manner of forming the stiliening member in one piece, this consisting of strip material having opposite, edge portions bent on a longitudinal medial line of the piece so as to dispose the edge portions at right angles to each other, the junction material of the strip at its central part being struck out at intervals to form opposed tongues 36 will ciently separated to form openings through the sti?ening member at the angle, and to receive wire intersections between the tongues 36. Welds are applied at the inner side of the piece around, , In Figures 6 and 7, structures are shown some what similar to that shown in Figures 1 and 2, and comprise identical metal strips 8 and 9, an gularly disposed, bisected by the end portion of the mesh material or the like and welded at the the wire intersections, so that the latter are root.- The strip 8 is placed in the same plane joined to the angle piece 35 thus formed.‘ as the mesh material, in order to obtain ?ush 20 In Figure 14, a, lower ?ange strip 31 is shown, faced panels. having positioned thereon, in spaced relation,‘ In Figure 8 there is shown a manner of form metal slugs 39, and an upper strip 38 is then set‘ ing one of the strips to be assembled from an upon the slug 39, at right angles to the strip 3‘! angle stiffening member, in which the edge por and the slugs. The screen material II is laid tion of one strip which is to be butted against the with its edge portion intersections upon the side of the other strip is notched at intervals cor ?ange strip 31 and set between the spaced slugs. responding to the spacing of the intersection of The weld material is then applied at the inner‘ wires or other elements in the open mesh mate side of the angle to join the two strips and the rial, the material It being trimmed on the line screen material, forming an angle corresponding slightly outward of the junction of the wires. 30 to that shown in Figure . ' After the trimming of the mesh material, its In Figure 15, specially formed strip material edge portion consisting of the intersections of the is utilized to produce the angle sti?ness, in this wires, is laid upon the inner side of the flange ‘case each strip being formed with any suitable strip 25, while the notched ?ange member 24 is set down against the other ?ange and so that the respective wire intersections of the material H are located within the notches. The weld ma terial is then applied within the angle, substan tially as at 16, in Figure 5, securing the two pieces 24 and 25 together, and securing the material H : to the assembled angle. In Figure 9, both strips 25 are notched in the manner shown in Figure 8, and instead of one of the strips being butted against the side of the other, they are both disposed at an angle to the plane of the material II and the weld is then formed substantially as shown in Figure 2. In Figure 10, each ?ange 29 of the sti?’ening member orangle is shown as having extreme edge portions pressed alternately in opposite di number of alternated o?set ?at portions 40, and inwardly curved sections 4|, so that when two' strips are brought together with the inwardly curved portions opposed to each other, the latter may contact, and form elongated slots 42 between the oppositely disposed ?at portions 40. In these slots the wire intersections of the screen ma. terial H may be respectively inserted and se cured as before indicated. , From the foregoing, it will be seen that the degree of angular relation of the two bisected strips may be subject to considerable variations for desired purposes, and that it is a general advantage of welded construction that great freedom of design is at disposal, and in the present case, the angular degree may be dis 50 posed in such way as to obtain greater rigidity rections, so that when brought together in proper of panels in a plane common with the mesh or angular relations with the formed edges adjacent may be altered to reach better rigidity in a direc each other and with opposed salients of the tion substantially at right angles to the mesh formed edges in abutment, as at 30, slots 3| are material. formed between the oppositely pressed portions While I have shown my invention with great which are not in contact, and this permits the in particularity, in its various forms, it is to be sertion of the intersections of the screen material understood that these are purely exemplary, and ll into respective slots, so that welding material that various other modi?cations may be made, may be formed at the inner side of the angle, sub as well as changes in the sizes, proportions and stantially as shown in Figure 2, or otherwise ac 60 construction of parts, as well as combination of cording to the relation of the screen material It equivalent elements, without departing from the to the formed angle. spirit of the invention, as more particularly set In Figure 11, it is shown how the strip members forth in the claims following hereinafter. 32 may be formed for accommodation of a heavy I claim: wire mesh.
