Specification of Letters Patent.

Application filed May 19, 1919. Serial No. 298,149.

To all w 220 272 may concern. 1 1T T n F no it ADOWII that i, bAROL ARON, a

citizen or the United States, and resident of Bridgeport, inthe county of F airfield and vto of Qonnecticut, have invented certain i and useful linproveinents'in Sectional for Concrete ll alls, of which the fol ng is a specification.

y invention relates to new and useful movements in sectional molds or forms particularly relates to means for molding hollow walls so-called, having air spaces therein to prevent dampness, cold or heat irorn going through. A

The feature of the invention is to provide a simplified form of mold which maybe ioruied entirely of metal parts, which are A orarily held in position during the pouring and hardening of the liquid cont is lower section of the form may be n out iroin time to time and replaced mold, to receive further quantities of ioand whereby the wall may be car- 1 up to the desired height. Further to go these sections so that they may be for molding one layer at a time or so they can he quickly and easily set up n: L f0l11 the inside of a building and pulation of a few nuts, bolts and .l parts and without the employextended braces or beams. 1th these and other objects in view the invention. resides and consists in the construe n and novel combination and ar 17a goiiaent o'l' hereinafter more fully described, illustrated in the: accompanying drawings, and pointed out in the claims hereto appended it heingunderstood that various changes in the form, proportion,

hollow concrete wall in the course of construrtion and having my improved mold section applied thereto, as would be reqiured in for concrete walls for buildings, and more and to design and construct the same an the top sectionto form extensions of scope of the claims may be resorted to the building of a concrete wall with an air space therein.

Fig. 2 shows a detached perspective view a sheet metal cover which I employ to cover tlietop edgoor the inner plates of the mold and the air space formed therebetween. g. 3 shows a plan view of the mold sec- @0318 as illustrated in Fig. 1.

Fig. t shows a vertical cross section through a portion of the mold sections and wall and illustrates the cover for the air spaces positioned thereon.

shows a detached side view or one t ner plates of the mold.

Fig. (3 is a perspective View of one of the spacers which are positioned between the inner plates, shown in Fig. 5;

Fig. 7 shows an enlarged detailed perspective view of the connecting end portions of the outer corner plates showing how the inner corners or the mold are formed, and

Fig. 8 shows a longitudinal section of two of the-outer plates showing how their ends are connected together.

In the drawings 10 represents the outer section of the wall, 11 the inner section and 12 the air space formed therebetweenxfll represents tie rods, the opposite end portions of which bent and embeddedin the two wall sections from time to time as the same is orricd up. There may be any desired 01. these rods to strengthen and station the wall and support one from the other.

J'Ehe outer plates which I have indicated by 1 iare formed of thin metal and are all alike in construction. They are preferaoly oblong and have a small angle iron 15 secured to their outer faces adjacent to their lower edge so as to leave a depending edge portion 16 that is positioned inside of the top edge of the lower plate. A flange 1"? is formed'along the upper edge of the plate and serves to support the before mentioned.

behind the offset 21 of the connected en'd ot'v These plates 14 are the adjoining plate.

further provided with i a central vertical angle iron that serves to stiden and strengthen the structure. Holes 23 are also formed through their lower edge portions to Patented Nov. 16, 1920. i

l ti

accommodate the bolts 2i that extend therethrough and through the vertically disposed channel arms 25 secured to the end portions of the bolts 24;. Washers 26 and thumb nuts 27 mounted upon the bolts 2% are used to draw the plates up into proper alined positionsaswill be apparent from the drawings. These bolts also extendthrough slots 28 in the lower edge portions of the inner plates 29 A second. series. of bolts. 30 are positioned upon the top edge of theseplates and each bolt is provided with ahead and collars against which. latter; the inner edge of theouter plates rest; Theseupper bolts. are alsoeaclrprovided with a washer anda nut 32 whereby the plates .areadjusted and held in alinementagainstthe collars. These upper, bolts pass through holes- 83:. in the inner plates 29 and serve to support: the

sameina manner which permits them to be v rles-of-oute'r. plates'ofunlform type to form theouter sidesofthe mold, bolts extending lifted out by the bolts.

Thespacer 34:. of which there may be any desired number is positioned between the two inner plates 29in a way to hold them} straight andat a uniform distance apart. These spacers include a T-shaped headhaving notches 35 upon the under side that. engage the top edge of theplates-in a" manner to prevent displacement. A shield 36 which may be of any desiredlengthis provided to cover; the air space and is formed of sheet metal and shaped to form two inclined side portions that not. only.

covei this space but direct the liquid concrete into the molds and prevent; it fromrunning into the air spaces, This shield is providedwith guardsB? upon its under side that fit down intoflthe space between the top edge portionof the inner-plates, in a way to amply. support the shield in position, but yet to allow of itsremoval as occasion 'may require. The inner plates which are used to form the corners of the;

mold are; provided with .angleirons; 38 and 39 as shown in Fig.3, and whereby one is supported against the otherand ina manner to prevent displacement. when the, concrete is poured in. A. strap 40 which is shown positionedagainst theouter side of the' outer corner plates serves to brace and.- support the plates. The end portions of said strap issupported by the upperbolts; 30 arranged upon the top edge of the plates.

' Thevertically disposedchannel arms 25.

areadaptedto be shifted-to form. upward extensions, when removing the. lower line of plates :forming the lower section of the mold,-

when theyare replacedabove, to build up.

the mold forbuilding on thetop. of the wall.

Thisis doneby. first removingthenuts; 27

1 and 4, and then drawing out the bolts and next swinging the brace upon the upper bolt 24, until the long arm 25 is brought to the 7 top (see dotted lines Fig. 1) and the short arm disposed downward thereby reversing the position and to form an extended support 'for the upper sections to be added.

,When this. is done the lower line or" plates are free to be removed and positioned upon the top edge of the upper plates and in which event the upper bolts 30 would be removedand again positioned upon the top 7 edge ofthe added plates so as to again formplates,.-braces positioned exteriorly of said plates and retainedin position by the plate connecting means, connecting means he tweenthe upper portions of the plates, and

a series ofinner plates, supported on the up- 7 per; connecting means to constitute inner spaced walls.

3. A sectional wall :IIlOld comprising a series of outer plates of-uniform type to form the. outer sides of the 'mold, connecting means between'theflower portions of said plates,- braces, positioned exteriorly of said plates-and retained fin-position by the plate connecting.;1neans,;- connecting means between theuppen portions of theqplates, a series .ofinnenplatessupported on the upper connecting; means .toconstitute inner spaced walls, and spacing members supported upon and positioned between the inner plates.-

Signed at Bridgeport, in the county of Fairlieldand State of Connecticut, this 17th dayfoji May, A. D.,,l919. and are positioned to support the plates- V r CAROL r.- nan-on; Witnesses i C. M. NEWMAN, LILLI NM. ALnrNc... V
