. j `Bert A( Olson, Maywood, Ill. f f Application March 11, 1938.v Serial No. 195,232 i 9 Claims. (Cl. 18S- 37)` i i I- This invention "relates` `to improvements in Fig. 13 is `an enlarged VBW taken 0n the line building beams andthe like `andgmore particu-` o l3`|3 0f Fig. 11. 1ar'1y,it relates to providing a strong, light-weight, Referring more particularly tothe drawings, I i h inexpensive beam for use inhouse building and have selected for the purposebf illustrating the 5 the like, y o principle of my invention af form I5 of beam `With the development of house building, espeshown in Figs.` l-5` having a right side member `It cially with the development of larger rooms in and a left side member I7 aS Viewed looking at houses, the Woodenbeam heretofore used has been Fig. 2. When these right and left side members found to be less and less desirable for this reason I6 and I'I are assembled, they have located bel0 and other reasons and there has been a need for t tweenthem` a pair of fillerA rails I8 one being 10 the development of a beam `having atmetal elelocated at the top andkone at the bottom, as will ment of minimumweight and requisite `strength be clearly understood from thedrawings. and 10W cost.` i i Each of the side members IB` and I1 has a cen- Oneof the objects of my invention has been to tral web, there being a central web I9 for the provide such a beam or structural element with right side member and acentral web 20 for the 15 such minimum weight and with all the strength left side member. integrally` formed with the requiredl o o I o o central webs I9 and 2li are outturned angular or `Another object hasbeen to provide such a beam horizontal flanges 2| and `22 for the webs I9 and ascanbe manufactured`inexpensively.` To that 20, respectively, there being anges at the top end I have provided a metalibeam made preferand bottomof each web.

It will be seen that the horiprovements made by `mefar more strength than zontal flanges 2l and 22`ntersect with the vertical y I y flanges 23 and 24 to formedges 21, and itwiii be The foregoing andf other advantageswill be readily understood from the drawings `that when i more clearly apparentfrom `what follows herein- `the right hand member I6 is placed opposite the after. The invention will bebest `understood by left hand `member I'I, as shown for example in reference to the accompanying drawings, in i Fig. 2, the horizontal and vertical flanges and the l di;

whichz` i f inturned extensions will form channels at the top 35 Fig. 1 is an elevation of abeam; i i and bottom ofthe right and left side members IE Fig. 2 is an end view `of thesame; `and I'I for receiving the filler rails I8.

Fig. 3`is a view taken onthe line 3-3 of Fig.` 1; The webs I9 and 2U areprovided with concave Fg- 4"S aVBW takeriori the linelI-II of Fig. 1; horizontal central beads, there being one bead 28` I I 4.0 Fig. 5 is a view taken on the line 5 5 of Fig. 1; for the web IS and another bead 29 for the web `20. 40

Fig. 6 is an insideview Vof `the left side member When the Webs are placedopposite each other, as ofthe two side members of the beam,` looking to shown in Fig. 2, it will be seen that these beads 28 the left as inFig. 2; and 29 register Witheach other in the form shown.

Fig. 7 `is a plan View of the Subject matter 0f In addition to the central beads just described,

` Fig. 6 partly `broken away?" i i the beamin the form Shown is provided with ver- 45 Fig. 8 iS an inside View 0f the right side member tical beads 3D at the ends ofboth webs and also of the two side members of the beam, locking to the right and left members I '.5 `and I'I are provided the right as in Fig.2; i with diagonal beads 3l, as can be clearly seen in i Fig. 9 is a plan `viewof the subject matter of I Fig. l. All of the beads 30 and `3I are provided i et Fie; A with fiareeboocssz attheirends. nwiubeseen so Fig. l0 is an exploded end view of a modied` that these flared boots are provided at the inter- `form; i sections of the diagonal beads 3| where they Fig. 11 is an elevation view` of themodied merge into the horizontal flanges 2i and 22, and form; also Wheresaiddiagonal beads 3I intersect with 55 "tFigglZ isanend view `of the same; and C the verticalbeads 30. `It will also be understood 55 that where the diagonal beads intersect with the central bead 28 they merge with this bead.

The vertical flanges 23 and 24 are provided with V- shaped depressions 33 and 34, the depressions 34 being deeper than the depressions 33 so as to provide an irregular interior surface for more securely locking the filler rails I8 in place. The edges of the flanges 2l, 22, 23 and 24 of the right and left side members have re-inforcing extensions 35 as can be clearly seen particularly in Figs. 1, 2 and 5. The webs are provided'with circular beads 36. Each of these beads surrounds an aperture, there being aperttures 31 in the web I9 and apertures 38 in the web 28. It will be seen that the apertures 38 are smaller than the apertures 31. When the right and left side members are placed in the position shown inv Fig. 5, for

example, the portion of the' webI member 295 surrounding the aperture 38 is punched through the aperture 31 and crimped on the opposite side of theV web member I9v to secure the two web members together, as will be readily understood without further description. It Vwill beseen too that the inturned extensions 25V and 2G are turned downwardly into the filler rail so as. to further secure the filler rail in place.

In Figs. lil-13, I have shown a modiiied form of beam. This form of beam is the saine as the form shown in the other figures excepting that, as clearly shown in' Fig. 10, instead of the outturned angular or horizontal flanges Zland 22 of the first form, there are provided outturned inclined iianges Zia and 22a. Instead of the ller rail i8, which is four-sided as shown in Fig. 2, there is provided a pair of filler rails 39- which are fivesided having inclined inner sides, that is, upper sides at the bottom and lower sides at the top 4B to conform tothe inclined flanges 2| and 22a cf the form shown in Figs. 10-13. It will also be seen that in the form shown insaid liigures, the diagonals are arranged after a diamond pattern instead of the angular pattern of the first form.

It .will be manifest that the arrangement of the flanges will provide for securely holding the wood strips in place, particularly in view of the inturned extensions of the vertical flanges and the V-shaped depressions on the vertical anges.

It will also be seen that the sections will have extraordinary strength despite their lightness, said strength being afforded by the reenforcement due to the arrangement of the central and vertical and diagonal beads with their flared boots merging with the horizontal flanges.

f It will also be seen that means have been made for providing for effectively securing the sections together. The advantages of the arrangement will be manifest to those skilled in the art without further elaboration. f An experience with my arrangement will show its advantages over beams heretofore provided. l

It will be understood that my invention is not to be limited to the structures shown, such as the flanges and beads and extensions and depressions, etc. What I have shown are merely forms of my invention. The sections "may be made cf steel or equivalent material.

While I have illustrated and described the preferred form of construction for carrying my invention into eect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set'forth, but desire to avail myself of such variations and modifications as comer within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
