On scription proceeds with reference to the accomhe ge e y p d der thus provided, panying drawings in which like reference charsubstantial flanges l5, l6, are secured in suitable acters designate like parts throughout the same, sp d relation, Preferably at the ends e f, ;and in which: as by welding H, or any other selected fastening 5 Fig. 1 is a fragmentary front elevational view means such as rivets, b mastic the like, of a portion of a building showing the outer ap- Capable of Providing Substantially g t pearance of a window opening embodying a preconnections of the flanges to the girder. Such ferred form of the improved lintel structure of flanges are extremely simple 1n construction and the present invention; may be produced in various forms at very low 5 rolled iron and steel or sheet metal. Preferably such a flange is provided as a substantial platelike element having its lower edge surface of a stepped formation corresponding to that of the girder such that it may be precisely fitted thereto to provide a close, water-tight connection by the welding or other securing means, as aforesaid.

Thus the lintel assumes the form of a unitary structural member having a generally stepped formation which may be readily embodied in substantially interlocked relation in the usual wall structure with little or no change from the cus tomary methods of construction simply by building the wall at the top of the window openingwith a substantial stepped surface, as; shown in Fig. 3, corresponding substantially to the Contour of the underside of the lintel-"The lintelis then most effectively seated on such surface of the wall and bridging the window opening 2, as shown, whereupon the building of the superstructure to be carried thereby. may be expedi-- tiously proceeded; with in. completing the wall structure..

Inasmuch as the .top surface of the lintel is open and of generally stepped formation, the immediately adjacent bricks or other material of the superstructuremay be readily built thereon in providing the aforesaid interlocked relation of the lintel in. the completed Wall construction whereby it is positively andfirmly held against displacement in anydirection. Thus the lintel-is held against inward. displacement bythe bricks [8, Fig. .3, comprising the inner portion of the wall at the top of the window opening in direct engagement with the rear face of vertical section is of the lintel. Likewise, outward shifting movement of the lintel in a completed wall construction is prevented by the bricks I9, 20, Fig. 2, carried thereby and directly engaging the upper surfaces of. the vertical lintel sections l2, l4 respectively. Endwise movement of the lintel in either direction is prevented by the end flanges H3, IE, on either side of which the bricks of the super structure are laid, as will be understood from the dotted line showing of Fig. l representing-themsition of such flanges ina completed wall construction.

A most important feature of this form oflintel structure resides in the provision of the end flanges l5, it of such configuration and design as to permit the same to be built into a completed wall construction without in anyway disturbing the customary staggered formation in which the bricks are laid. Accordingly, asshown in Fig. 1, it will be understood that brick 2l of the wall directly overlying the flange for example, is suitably clipped as indicate'dat 22, Fig, 2,'such that the same will clear the free edge of such flange and thus be capable of being precisely embodied in the conventional staggered formation in which the bricks are laid in the completed wall construction. The outer appearance of the wall,

therefore, is in no manner detracted from and since the spaces intermediate adjoining bricks are cost in the manner of inexpensive stampings from lintel construction of this character which overcomes all the insufliciencies of known prior conv 'structions att'he least possible cost.

The flanges l5, IE, on the lintel are suitably spaced from either side of the window opening as shown in Fig. 3 and thus provide a substantial receptacle into which water flowing from the super-structure above the door or window opening will be collected and be prevented from running on the ends of the lintel into the area of the wall surrounding. the window opening. where it would tend to seep through. and dampen the inside of the wall. Accordingly, any water collected between such flanges l5, It will naturally havea tendency to flow down. the stepped formation of the lintel'to the lower horizontal section I I thereof, which as shown. in Fig. 2, has its free edge in the area of the window opening 2 and will, of course, discharge such shedded water outwardly outsidethe wall.

-Fig. 4 showsla further embodiment of the invention in which a generally W-shaped. lintel of the character described with reference to Figs. 1 to 3 inclusive is employed with an alternate form of flange means provided byindividualsubstantial angle plates 30,-3l, and. 32,33. These angle plates are constructed of. any suitable ma terial suchas iron, steel or sheet metalmaterial and are arranged on the lintel in a manner to dispose the respective free flanges 34, 35,. and 36, 31, thereof in suitable offset relation to precisely fit in the arrangement of the bricks of the superstructure which. may then be readily built up on thelintel without departing from the usual staggered formation oflthebricks-in the completed wall construction. Such angle plates may be rigidly secured to the lintelby any suitable means such as welding, riveting, etc. but inasmuch as the same are provided as individual elements they J are preferably united to the lintelby a suitable form. of mastic applied over a substantial area of'the side and bottom surfaces thereof seated against the adjacent vertical andhorizontalsecti'ons, respectively, of the lintel. It will accordingly be appreciated that the said flanges34, 35 and:'36, '31, serve in a manner similar to-those described in the previous form of the invention, to prevent shedded water from above the window opening from running off the ends of the lintel into the surrounding wall area, and .otherwise direct such water down the stepped surface of the lintel to the free edge of the lower horizontal section I la thereof where it is readily discharged in the area-of the window opening outwardly outside the wall.

Figs. 5 and 6 illustrate another formof the invention wherein the lintel structure is provided by'a pair ofangle sections 46, 4|, arranged'one upon the other in offset relation, as best'seen in Fig. 6, with the horizontal portion of the'upper angle section 40 overlying the adjacent'vertical portion of angle section 4| to provide the generally W-shaped girder arrangement which may be readily embodied in the ordinary wall construe-- tion, substantially as set forth with respectto the form of the invention shown in Figs. 1 to 3. inclusive. This arrangement embodying a pair of separate angle sections isparticularly advantageous in installations in which cost is a deciding factor sincesuch angle sections are usually ,of stock dimensions andtherefore may be obtained at comparatively low cst., v v Q i In a lintel structure. of this character, a substantially water-tight bond therebetween can be obtained by employing a mastic or the like, between the top edge of the verticalportion of angle section 4!, and the overlying horizontal portion of angle section Mi. The flanges maybe provided by suitable plate elements individually secured to the separate angle sections, 4%, 4|, by welding, riveting or the like, or otherwise provided for in the use of substantial angle plates similar to those shown and described with reference to Fig. 4, and accordingly, in a completed wall construction, such flanges 36, 35 would assume the form substantially as indicated by dotted lines in Fig. 6, showing in detail the general type of window head construction set forth in the description of the form of the invention shown in Fig. 2.

An alternate construction of this form of the invention contemplates welding together the two angle sections preferably in the area in which the horizontal portion of angle section 40 overlies the vertical portion of angle section 4!, thus providing a unitary structural member of the same character as the one-piece, generally W- shaped type shown in Figs. 3 and 4. The end flanges therefor may then be provided either by means of individual angle plates as shown in Fig. 5, or in the manner of simple, inexpensive platelike elements similar to the flanges l5, [6, Fig. 3, and which when welded or otherwise secured to the pair of angle sections serve to reinforce and strengthen the lintel structure thus provided.

While this invention has been described in detail with specific examples such examples are illustrative only, since it will be apparent to those skilled in the art that other modifications within the spirit and scope of the invention may be constructed without departing from the teaching or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
