l/'o all whom t may conce/ra.'

Be it known that I, Srrmci H. 'lnoimnrniUsnR, a citizen of the United States, and a resident of Minneapolis, county of Ilennepin, State of Minnesota, haveA invented certain new and useful Improvements in Buildingrlvalls, of which the following is a specification.

My invention rela-tes to walls for dwelling houses and otheiI buildings of asimilar type and the object of the invention is to provide a means for utilizing a concrete construction without additional metal reinforcing means which adds so much to the expense and labor of building a concrete wall.

A further object is to provide a wall which willvbe fire and sound-proof and will also be insulated against the transmission of moisture resulting from variations in the temperatureto which the wall is exposed.

A further and particular object is to yprovide a wall constructionrwhich will be simple and inexpensiveand at the same time be extremely strong and durable and may be easily made to meet the artistic requirements of modern architecture.

The` invention consists generally in providing a form, either wood or metal, as preferred, pouring the concrete therein and` then putting the finishing coat of plaster on the form which, after the concrete becomes set, forms a jacket or shell therefor.

Further the invention consists in various constructions and combinations, all as hereinafter' described and particularly pointed out in the claims.,

In the accompanying drawings forming part of this specification,

Figure l is a horizontal sectional view through a portion of a building wall em, bodying my invention,

Figure 2 is a vertical sectional view on the line 2-2 of Figure l,

Figure 3 is a. modilied construction, showing an air space on both sides of the concrete wall,

Figure 4 is a view corresponding to Figure l, showing the invention applied to a metal form of construction,

Figure 5 is a vertical sectional view on the line 5-5 of Figure 4t,

Figure 6 is a. detail sectional view, showing the manner of mounting the expanded metal lath or fabric on the wall or frame of the form,

Figure 7 is a similar view, showing an other means for holding the fabric on the form.' f l In the drawing, Figure l, 2 represents the outer upright studs and 3 the inner opposite studs secured to the outer studs by suitable means, such as the shortl transverse slats or lath 1l placed at suitable intervals, as indicated by dotted lines in Figure 2. The-studs are placed the usual distance apart in wall construction and are connected by lath 5, horizontally arrangedbetween the studs. I, prefer to place sheets of suitable building paper 6 which serve as a means to prevent the liquid` concrete from flowing outwardly between the cracks of the lath. Similar lath are secured to the inner vertical edges of the studs 2 and building paper 6 may be interposed between these lath and the studs.` The outer vertical faces of the studs 2 are provided with horizontal lathV 5b, spaced apart as usual in the manner of laying lath. Between the latli 5? and 5b a dead air space A will be formed and in the space between the lath 5 and 5a the concrete to form the wall-is formed, resting upon a suitable foundation F, as indicated in Figure 2 and in which the floor joists 7 may be mountedt At the corner of the 'structure the studs 2 may be placed backV to back, as indicated at 8, and then the other` wall running at right angles may be formed in a similar manner. The inside finish plaster will be applied, to the lath 5 and the outside stucco will be ap,-v plied to the lath 5b, thereby completing the interior andexterior of the wall.

From the foregoing description it will be noted that the form into which the concrete is poured is not removed, as usualin concrete structures, but remains yas a framework or skeleton enclosing the concrete and providing suitable air spaces inthe wallv and suitable means to which the finish plaster on the inside and the exterior stucco may bel secured. I do not propose to utilize high grade lumber in this form, as it is not necessary as a mold for the wall, it being merely suficient to support the concrete until it becomesset and then the concrete supports the skeleton frame.

The width of the air space and the relative location of the studding may, of course, be varied according to the height of the building and the character of the climate where the structure may be erected.

In Figure 3 I have shown a modified construction which consists in providing iio upright studding 9 on the inner lath and then providing another layer of lath 9L to which the inside linish plaster is secured. A double air space is 'thus crnied in the skeleton trarne between which the concrete is poured.

In Figure l: l have shown upright angle bars l() arranged at suitable intervals on the inner side ofthe wall and channel bars ll. opposite the angle bars on the outer side of the inold or trarne. rhese angles and channels are preferably pressed or rolled 'from thin sheet metal and Will have no particular function or supporting the concrete, as the reinforcing metal would, but are nier-ely intended as a support :for the metal latli between which the concrete is allowed to run. rllhese angle bars l() have lugs l2 pressed therefrom, provided'rvith holes 1.3 therein and the Wire or expanded inetal lath lei is placed against the angle bars with the lugs inserted through the nieshes or slots oiV the lath and the lath is then locked on the lugs by the insertion oit small Wire rods l5 through the holes. Corresponding lugs l2 are pressed f om the channels ll and adapted to enter the meshes of the fabric or the slots ot the expanded metal 'for locking the plates or sheets against the upright channels. 'll he channels and angle bars are held in parallel relation by the cross slats 16 secured thereto at intervals and embedded in the concrete when it is poured between the 'outer and inner plates of the lath. A dead air space l? is 'l'orrned between the lath, secured to the inner face of the channels and the corresponding lath on the outer face, and Whenever necessary, sheets of building` paper may be interposed between the angles and channels and the lath for holding the concrete until it becomes set,

ln Figure 6 the details of one Way of mounting the metal lath on the stupporting` bars is shown and in Figure 7, instead o1 providing lugs pressed Yfrom the bars With holes therein to receive the locking Wires, l bend the lugs to the position indicated at 18 Where they press on the Inet-al lath or fabric to lock it securely in place so that the paser coat can be easily and quickly app1 1e v This structure is substantially the saine as described With reference to Figures l, 2 and 3, except that light nietal is used in place ci Wood and the lath is composed of fab 1ic or expanded metal or any of the Welllrnoivn conventional nietal lath instead of the Wooden stripsv or slats shown and described With reference to sheet l. may provide a dead air space on each side of the concrete Wall where the metal traine work is used, illustrated in Figure 3 of the Wooden construction. This. however,v 'would rnerely ainoui t te anchori be additional angle-oi.l channel bars to the inner bars of the skeleton traine and then placing` sheets oilz fabric or expanded metal thereon.

claini iny invention:

l. building wall comprising inner and outer groups oit upright members arranged in parallel relation and having cross bars secured to the opposite inenibers of said groups, lath secured Ato the' outer and inner iff; t one said group oit upright ine1nbers, lath secured to the inner faces of the other group of members and forming With the rst lath a space for pouring concrete therein7 and the lath secured to the inner ineinbers andthe outer faces of the outer members bein. adapted for receiving finish coats in plastic forni.

building Wall comprising inner and outer Wooden uprights arranged in pairs in parallel relation and spaced apart, tie bars secured ay their ends to the opposite up rightfft lath secured horizontally to the in ner and outer faces of one group of uprghts, and to the outer faces of the other group of uprights said lath co-operating With said uprigbts and said cross bars'to 'torni a` skeleton ,i aine, a dead air space beii'lg provided between the lath on the inner and outer races of one rgroin) ot iuyrights and the space between the groups of uprights being filled with av nzaterial in plastic torni, a finish coat in plastic iorin applied to the outer lath ot onev group oiV uprights, and a second interior finish coat appliedto the lathl of the other group of uprights.

ln Witness Whe-recit7 l have hereunto setv my hand this 26th day of January 1920. Sltlll` El H. TRMANHAUSER.
