IPAWLING-,lOF IPI-IILADELPHIA, PENNSYLVANIA, ASSIGNOR TOTAWLING SYSTEM, INC., 0F PHILADELPHIA,PENNSYLVANIA, A CORPORATION OF DELAWARE BUILDING CONSTRUCTION Application filed November 27, 1925. Serial No.` 71,535.

This invention, stated in its broadest terms, relates to building construction and has more especial relation to the erection of structural members such as fioor and ceiling girders or beams and the manner of concealing same with a concrete surfacing.

' As at present practiced, commercially considered and after girder or beam erection, it

cordance with concrete engineers methods, to erect' around the beams or glrders a temporary wooden structure (as used in all concrete work) to sustain the concrete pourfor concealing` said beams or girders. Practice dictates that this is a relatively expensive procedure since not only does it require expensive material for temporary use but skilled mechanics in addition are essential, to say nothing` of thelabor entailed after the set of the concrete in tearing down the temporary wooden structure. Y

The leading objectfof the present invention is to overcome the above described disadvantageous features and provide a building structure of the character under discussion in which first: all temporary wooden supports are eliminated thus expediting working conditions, reducing cost of erection, eliminating skilled workmen and materially reducing erection costs; second: providing a pressed steel metal lath support so constructed at themill that it is ready for Abeing y bent and fitted beneath the lower part ofV a beam or girder and maintained in position without the use of nails, wire, or likemediums (requiring time and expense) to support expanded or other metal lath. Other and further objects reside in the provision of general details of construction and arrangement and combination of parts forattainin'g the results sought by the foregoing objects. I i

Other and further objects not atthis time zfippearing will be hereinafter more fully set orth.

The invention consists of the novel con-` struction hereinafter described and finally claimed. 7

The nature, characteristic features `and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

Fig. l, is a fragmentary view,` in section,

illustrative of a beam or girder concealed in tion I have shown in the accompanying drawy ings one form thereof which is atpresent preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization ofthe instrumentalities as herein shown and described. y

In the drawings and referring nowmore particularly to Figs. l and 2, the reference numeral l designates a beam or girder as usually employed in floor and ceiling building construction. Such beams or girders are spanned by any suitable joist as for instance skeletonized joist 2 such as exemplified in various of my pending applications for patents and which forms no part of the present invention. Any conventional form of fiooring, as concrete 3, maybe employed. In formation of the concrete ceiling, designated 4, in Fig. l, obviously` it is essential to conceal the bottom of girders l and this is conventionally practiced -by constructing a wooden structure beneath the beam or girder bottom and providing a concrete fill. According to my novel structure, however, I provide metal lath supports 5 formed of sheet metal and stamped from a -single blank in the form shown in Figs. 3 and 4, and also auxiliary metal lath supports 6 as shown in Figs. 5 and 6. These are formed around the bottom of the beams or girders, the ends fitted together, telescopic fashion, and the supports 5 sustained by inverted, U-shaped wire members 7 which rest upon a beam or girder top and depend therefrom and have their hooked ends 8 engage beneath the metal lath suports 5. Thereafter the usual metal lath 9 1s caused to engage the clips 10 and 11 of the supports 5 and 6 by causing the slits or apertures therof to engage said clips 10 and 11. The concrete fill 12 which not only forms the ceiling but conceals the beam or girder bottoms is then poured without the employment of any temporary wooden structure heretofore necessary thus greatly expediting erection and materially reducing cost thereof. In order to accomplish this result I fabricate special metal lath supports 5 and 6 as above mentioned. The special form of support-5, as shown in Figs. 3 and 4 is stamped from a single piece of sheet metal, U-shaped fashion with the clips 10 struck out from the bottom thereof. One end of each support is contracted by folding or bending to form a nib or projection 13 and the opposite end is folded or bent over to form a socket 14. At suitable intervals the side walls of each member 5 are oppositely stamped out to form V-shaped openings or vents 15. Thus by placing a support 5 beneath a girder or beam 1 and bending same vertically at each end, about said V-shaped vents 15, the position shown in Fig. 1 is attained. The nib 16 of auxiliary support 6 is then' fitted to socket 14 of support 5 and the socket 17 of a second support 6 fitted to the nib or projection 13 of support 5 all as very clearly seen in Figs. 1 and 7. Thile it is not ordinarily necessary to secure, by pins or the like, said fitted ends together, I provide apertures 18 and 19 in said supports 5 and 6 should it be desirable so to do.

It will now be apparent that I have devised a novel and useful construction which embodies the features Vof advantage enumerated as desirable in the statement of the invention and the above description and While I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spiritor scope of the invention or sacrificing any of its advantages.

What I claim is 1. In a building Vconstruction including a beam or girder for floor support, an inverted U-shaped member' having hook-like ends carried said beam or girder. a main metal lath support having a weakened portion adjacent each end suspended from ,said member and having said weakened portions upturned, an
