LINTEL -Applicatlon filed June 8, 1921. Serial 1T0. 475,937.

This invention relates'to metal beam suprts, and more particularly it relates to a E am of a predetermined design ca able of a particular. and definite use in buil mg con- 5 structions.

One of the objects of this invention is to provide a unit metal beam having a portion thereof designed to support a ma n load and another portion designed to support another part of the load in a particular maimer.

Another object is to provide a unit beam, which has a special use as a lintel for door andwindow openings in building structures, and which has an integral portion thereof of proper size and contour to support facing desirable to employ metal beams as lintelsfor the door and window openin s, as the other types of beams sag or ben thereby permitting the walls to crack and split open thus giving entrance to the weather elements. Heretoforemetal beams have not been employed for this purpose to an extent commensurate with their desirability as they have only been constructed with a view of obtaining sufficient strength. Another reason for not employing the metal beams of prior construction is thatthey have not been formed so they willsu port a facing ma terial. These objections l'iave been overcome by the resent invention which is directed to a nove beam construction which incorporates certain desirable practical features as well as being of proper strength.

In the accompanying drawin s which form a art of this specification, t ere is illustrate a selected embodiment of this invention wherein,

Fig. 1 is a view in perspective of a portion 0L a beam of thenovel construction.

' material.

Referring to the drawings and particularly to Fig. 1, a beam of the new construction is illustrated as being a unit member having a web portion 1, flanges2 and 3 integral with the web and extendin therefrom on the same side, and a third ange 4.- also integral with the web and extending from the opposite side of the web. In this preferred con-- struction the beam is formed so that the main or direct load is carried by the portion of the beam comprising the web and the flanges 2 and 3, while the flange 4 supports another and much smaller load which is the facing However it is to be understood that the flange 4 may be formed to materially increase the strength of the beam as well as performing its special function of supporting its load in a predetermined manner.

- Usually the beam is rolled from a steel ingot or bar.

This beam has, among'its several uses, oneparticular and specific use wherein 1t meets.

a need which has been present for a considerable length of time, and which has not been fulfilled by an article meeting the functional I requirements as well, as beingof sufiicient strength. This new type of beam is readily manufactured at a cost substantially less than other beams which might be constructed to meet the need. This specific and particular use is that of a lintel in building con struction wherein the flange portion 4 is particularly adapted to readily support the building or facing material covering the beam to have the material align'with the contour of the building and to have this material placed in proper position without being cut or trimmed or required to be specifically formed to fit a particular contour of a beam.

In the old building construction, the common I-beam has been employed as a lintel, but in such instances the external face of the beam has been left exposed to the weather thereby making an unsightly building contour, or other and special materials have been employed to cover the exposed face of the I beam. In the last instance material other than the main construction material have been employed: to cover the beamand to makethe building contour even. For in- .stance when the vexterior surface of a build building contour in the event that it could be supported on one of the I-beam flanges.

In the specific use of the beam illustrated a brick without requiring the same to be trimmed or specially fltted to the flange. A beam of this form when specifically employed as a lintel, permits the facing material to be quickly placed in position on the flange, and in line with the exterior surface of the building contour. It is to be understood that the flange 4; may be of any desired design which will allow the facing'ma terial to be easily and quickly placed in position and held in line with the building .contour.

Certain modifications may be made in beams which include the foregoing advantages, and reference is made to Figs. 2, 3 and 4. showing some of the modifications. In Fig. 2 there is illustrated a beam having a tongue '5 which acts as an abutment for a door frame or a window sash. This tongue also functions as a stop to prevent the weather elements from passing directly between the base of the beam and the window sash. In Fig; 3 a form of beam is shown wherein the flange 4 is located in a plane below that of the plane in which flange 3 lies. Vvhen the flange 4 is offset, a face 6 functions as an abutment for a door frame or window sash. The flange in oflset position also functions to prevent the weather elements from passing to the interior of the building construction in the same manner as tongue 5. It is to be understood that modifications of the tongue 5 and of the base 6 which act as abutnients may be made but that such modifications should give irregular contour to the under side of the base of the beam and which modifications are so formed as to receive a construction article in a manner to maintain this article in desired position and to assist in preventin the passage of weather elements between the article and the building construction. There is illustrated in Fig. 4 a beam which takes advantage of the strength of flange l to increase the total strength of the beam while the top surface of this flan e is still maintained substantially per pendlcular to the web in order to properly support the facing material. Such a beam has its strength balanced by increasing the size of flange 2. l

Specific application of the improved-beam to a brick building structure is illustralcd in Figs. 5 and 6. In Fig. there is shown a sectional view of a brick wall showing the ends of an I-beam and my improved beam at their points of support. One form of beam embodying this invention is shown at 7 with the flange 4 resting on the brick -work and theflange 3 on the usual plate 8 width of the flange is substantially that of the width of a brick and therefore the brick 10 for facing the beam are easily placed in position and are held so the centcrline of this facing material is parallel to a vertical plane passing through the web of beam 7. By having the top surface of flange 4 substantially perpendicular to the web, the brick employed as the facing material are placed in position without being specially trimmed and they conform to the contour of the building outer surface. The space between the beams and other spaces which are later covered by wall paper or the like, may be filled with concrete or like material.

Fig. 6 shows in section the construction over a window opening and illustrates the particular use of the beam as a lintcl which supports the super structure, the facing material, and receives a window frame 12 against face 6. A portion of a window sash 13' is shown in position co-operating with the frame 12. With this design. of beam for use as a lintel it is to be noted that rain water in passing down the facing material will not pass to the interior of'thc window frame as it will drop from the'lowcr side of flange 4: or will pass over the external surface of frame 12 and down on to the window glass. In thi connection it is also to be noted that dirt and dust will not be blown to the inner side'of' the building or window as the window frame sets snugly against the lintel.

lVhile the preferred type of beam has been described for a particular use, it is to be understood that it may be employed for other uses as for example, a duplicate beam may be placed at the inner edge of the wall with the flange 4.- extending to the interior of the building so that it may be employed as a support for the ends of girders.

Other uses and modifications may suggest themselves, but they are considered as being within the scope of this invention as outlined by the following claims.

What is claimed is:

1. An article of manufacture being a beam integrally formed and having two strengthening flanges and a third flange, one of said strengthening flanges being at the top of said beam and the other two flanges being at the bottom thereof, said beam having the under side of its base constructed of irregular contour between the edges of the two lower flanges to form a holding means for receiving and positioning another article of building construction.
