Lemon wnarz or OAK PARK, ILLINOIS CONCRETE-"FORM Application filed June22,
This invention relates to certain novel improvements in concrete form constructions and has for its principal object the provision of-an improved construction of this char- 5 acter which will be highly eflicient and economical in use and manufacture.
It is among theobjects of my invention to provide a concrete form construction which willbe particularly adapted for use in the formation .of one floor and the supporting beams therefor above another and consists in providing a construction which will not require the usual shore constructions to support the forms. Inasmuch as I am enabled 5 to eliminate these shore constructions I am enabled to bring about a great saving inthe material employed in the construction of concrete forms.
.:Another object of the invention is topro- 9 vide a construction which will'employ rigld reenforcingmembers whichwill be used to support the'forms in which the concrete is to be poured and supported during hardening I Another object of the invention is to provide a construction which will embody parts that may bev supported from the reenforcing members and consists in, arranging these parts so that they may be secured to the reenforcing members through themedium of supporting wiresor the like. 7 "A still further object of the, invention is to provide a construction which will be:ar-. ranged so asto provide securing members for the metal lathusually employed in connection withreenforcing concrete constructions. 7 V v j Other objects will appear hereinafter. The invention. consists in the novel combination andarrangementof'parts to be 'hereinafter described and claimed.
The-invention will be best understood by reference to the accompanying drawing,
showing the preferred form of construction Fig. 1 is a transverse sectional View of a preferred form of construction for my invention-showing the concrete pouredinto' my form construction; I

Fig. 3 is a .fragmental-viewlookingin the same direction as Fig. 1 depictingamodified form of construction; r ,55
In the accompanying drawing wherein- I 4 have illustrated a preferred form of construc- I tion for my invention 10 genericallyindicates a, so called rigid reenforcing. member which is'preferably formed from three sections 11, 12, and 13, the section 12 being arranged intermediate thesections Hand 13. The section 12 embodies an upper rai'l'14 and a lower rail 15 which'extend substantially parallel to each other. The section 11 embodies an upper rail 16 and a lower rail 17. The lower rail 17 includes an upwardly extending port-ion 18 at one end thereof which extends upwardly from the rail. 17 in spaced relation with the end of the rail.15 79 and includes a. foot portion which is arrangedparallel to the rail 16. A similar. section 19 extends. upwardly at the opposite end of the rail 17 and also includes a foot portion which is disposed. parallel to the adjacent end of the rail 16. The section 13 is formed similar; to the section 11 and it is, therefore, manifest that the ends of the rail l5'extend beyond the endsof the rails of the outwardly dis.- posed sections. V 3
While I have setforth the'above described construction-for the reenforcing members it is to be understoodthat other arrangements of reenforcingmembers might be provided ,without departing froin the purview of my 35 invention. The reenforcing-membershave 8 extending therebetween reenforcing strips generically indicated by 2 0 and these reen forcingstrips- 2Ov extend between theupper and lower rails of each of the sections 11 12, and 13. 1 i
As is well understood in the art metal pans are usually employed "to provide the forms into which the concrete may-be poured and in which the concrete :mayha-rden. Such 9 metal 'pansare generically indicated by 21 .in thedrawing' and are usually formed so as to be substantially U-shaped ,in transverse section and comprise bight portions 22 and limb, portions 23 and 2% which extend from 9 1 tween such beams,
2 "1,887,355 the bight portion 22 and provide adjacent I then provide a supporting plank which sides for juxtaposed beams; that is, the side 24 of one pan co-operates with the side23 of an adjacent pan so as to provide side walls for a given beam. v
It is manifest that my invention is intended to be used in connection with the construction of so called reen'forced concrete buildings. In the construction of such buildings vertically extending columns are provided and extended between these uprights are longitudinally extending beams which provide Certain of these longitudinal supports extend between thecolumns which define the outer walls while other of these beams extend between the supporting columns arranged. interiorly of the walls and the beams which are to be formed. The metal pans 21 are intended to extend beit being obvious that these beams will extend parallel to certain of the beams in the walls. IIoweventhe beams I intend to form are employed in my construction as the supports rather than the shores usually provided. In the drawing I depict the forms in which such beams are molded and these forms are indicated by 25 and 26.. Extending up from these forms are support support thebars 14 and 16 of my rcenforcing members ing members 27 and 28 which and the end portions of these bars extend beyond the supporting members 27 and28. It is manifest that if the beams 25 and 26 have been previously formed the supporting menu'- 5 bers 27 and 28 will be arranged to extend upwardlyfrom'these beams. I also preferably extend the lower rail 15 of the section 12 toward and if possible into the beams to be formed in the forms 25 and 26 which manifestly rigidly supports the reenforcing members 10. 1 At suitable intervals along the reenforcg member 10 I provide connecting members whichare indicated by 29 and which are, in the present instance, in the form of wlres. These wires are passed over the lower rails of the sections 11, 12, and 13 and are bent so that portions thereof will extend downwardly. 1 I then provide the substantially U-shaped spacing elude foot portions 31 and 32 atthe outer ends of the arms thereof. The bight pertions of the spacing members 30 are disposed in abutment with the rail 15 and, therefore, the foot portions 31 and 32 are disposed outwardly and preferably extend outwardly a distance 'suflicient to engage the downwardly extending portions of the wires 29. I then provide supporting members or troughs generically indicated by'33 which are formed so as to be substantially U-chaped and which include bight portions 3 1 and limb portions 35 and 36. Openings are provided in the bight portion 34 through which thc'depending portions of the wires 29 are extended.
After the pans 21- have been arranged in position in the manner set forth the concrete is poured into the pans a-nd permitted to harden. After hardening the twisted portions 38 of the Wires 29 are cut away which leaves portions of the wires depending from below :the lower endof the beam formed by the hardening of the concrete. After the twisted portions 38 have been cut away his manifest that the plank 37 maybe removed and the trough 33 also removed and, therefore, the pans 21. The ends of the wires 29 depending below the beam may then be employedfor securing the metal lath for the ceiling which will be arranged-below the beams thus I necessary to provide additional wires to support these laths asis thecustom at the present time. Y v f I It-is manifest from the foregoing description that I have'provided a'construction in which the metal pans for supporting the concrete during hardening will be effectively supported from the reenforcing members and I am, therefore, enabled to eliminatethe formed and, therefore, it is not" than once. yItis, therefore, readily apparent that a great saving is brought about through the employment of a construction such as that set forth." 7 V g :In addition to the foregoing arrangement I have shown in Fig. 3 a modified form of construction which may be employed when so desired. -In= this -modified formof,-'construction metal pans generically indicated by 41 are provided which are shaped substantially similar to the metal pans 21 and which include limb portions 42 and 43 which cooperate in a manner similar to the co-operation between the limb portions 23 and 24 to form a beam. In this instance the limb portions 42 and 43 have lug portions 44 and 45 extending inwardly therefrom in spaced relation with the lower ends of the limb portions 42 and 43. In thisconstruction I employ wire members 46 that are substantially similar to the wire members 29 and these wire members 46 are passed over the lower rails of the sections of the reenforcing members in a manner substantially similar to that in which the Wire members 29 were passed over these rails. In this instance I employ a plank 47 which abuts against the lower surfaces of the lugs 44 and 45 and the inner surfaces of the limbs 42 and 43 which de-' pend below these lugs. The ends of .the wire members 29 are passed through openings in the plank 47 and are intertwisted as at 48.,
It is, therefore, manifest that the plank 47 e not only effectively supports the metal pans 41 but also provides the lower wall for thebeam. In this construction after the concrete has been poured and hardened the intertwisted portions 48 are cut away and theplank 47 is removed as well as the pans 41. and in this construction the ends of the wire- 46 will also depend so that metal lath may be secured thereto.
It is manifest from the foregoing description that I have provided a construction forconcrete forms which will be very economical in use and one which may be expeditiously installed. It is also apparent that the con-- struction provides fastening elements for metal lath so that additional members need not be provided for this purpose.
While I have illustrated and described thepreferred form of construction for carrying my invention into effect, this is capable of va-- riation 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 come within the scope of the appended claim.
Having thus described my invention what I claim as new and desire to protect by Let ters Patent is: 8 7
Means for supporting a concrete beam form from reenforcing members adapted to be embedded in concrete molded in said form, said form including spaced portions extended toward each other at the lower end of the form, comprising a trough member adapted to, receive said spaced portions, a member including limb portions disposed in said trough member and abut-ting said spaced portions, said last-mentioned member intion projecting upwardly from the trough member and abutting one of the reenforcing' members, a plank below the trough member, and a flexible member wrapped about the reenforcing members, said flexible member extending between. said spaced portions and said limb portions, and through said trough member, and having free end portions intertwisted about said plank, whereupon by severing said intertwisted portions said plank, trough and beam form may be removed and the severed ends of said flexible member may be employed to secure ceiling lath thereto. In testimony whereof I afiix my signature.
