MONOLITHIC, METALLIC REENFORCED SLAB Filed Jan. 23, 1932 2 Sheets-Sheet 2 Patented June 30, 1936 unirse stares PATENT OFFICE IVIJNMTMC, METALLIC-REENFRCED SLAB v: ,5; V nn Application .sanitary lviy invention relates to veneers application the external walls of buildings. Primarily, l' concerned with a veneer which :nay be quiclily applied to a Wall, and, upon suon application, will lend to the Wall an appearance of masonry. Broadly, this concept has for years been in the minds of those skilled in the art, but to my knowledge there has been no veneer structure embodying the particularly effective characteristics of my invention.

While the novelty of combination in the appended claims may be of speciic nature, it is nevertheless of great' practical value. lvly structure comprises a monolithic, metallic-reenforced slab which has incorporated in its body plaques resembling in elevation the members oi the inasonry which in service the veneer is to reproduce. It will be observed that an important' characteristic of my veneering slab lies in the fact that it includes a plurality-or" preformed, burnt briquettes (plaque members) spaced apart and arranged in predetermined pattern; the body material of the slab extends into the intervals between the briquettes, so that when installed upon a Wall, the Wall -taires on the attractive appearance of laid bricl; masonry-practically no pointing or lling in of the slabs being necessary after installation. In brief, it is only necessary to apply my slabs to a Wall, and, Without further labor, the Wall is attractively nished.

inl the accompanying drawings Fig. I is a vlevv in side elevation of a slab embodying the invention, indicating ragmentarily three associated slabs;

Figs. li, m and lV are fragmentary views in cross section, to larger scale and taken respectively on the planes H E, mmm, and V-W of Fig.

Fig. V is a fragmentary sectional view, to still larger scale, illustrating how the veneer may be conveniently secured to a backing wall;

Figs. Vl and VI are views comparable with Figs. li and H, respectively, showing a modification in the structure of the slab veneer;

Figs. 'Vm to Xl inclusive illustrate still other modications; and,

Figs. XH and m show a mold fragmentarily, and illustrate how the veneer slabs may be constructed.

The veneer structure of my invention comprises a plurality of briquettes l; the briquettes may be vof desired shape and color, and in thiscase, the briquettes are preformed of clay and burnt in kilns, as standard bricks are made. The briquettes are relatively thin, so that the expanse of brioi lr'ennsyivania 23, i932, lilo. 588,323

ailettes is of slight thicln'less, conservation ci terial and minimization of Weight desi ata. The expanse of briduettes is supported on one face in a monolithic slab 2 of cementitious material, which in this case is a rich, line concrete. Within its body, extending in the general plane of its expanse, is a metallic reeniorcernent 3. Light-Weight metal lath or other Well-known perforaternetal sheets may serve as the reeniorcement. At various points throughout the slab structure holes l are provided for attaching screws or nails. Fig. V illustrates how a nail 5 may be driven through each hole d into the backing Wall l which is to be faced with the veneer. The nail holes lie between the briquettes and are countersunk, as indicated-thus mortar 'l can be spotted over the nail head.

lt is of importance to note that the body of the slab 2 extends into the intervals and provides iillets between the briquettes. All or a portion of the cementitious material forming body of the slab may be colored when in the green state, so that in assembly and in completed state the cody o1" the slab 2, by extending into and appearing Within the intervals between the briquettes, lends to the Whole, in side elevation, the pleasing appearance of nicely pointed briclr masonry. in deed, the structure practically avoids the necessity of pointing which is necessary in all practical slab veneers in use today.

In case the slabs are terminated at their edges intermediate the intervals between alternate briquettes (ci. Fig. I), it Will be necessary to ill in and point the regions 8 between adjacent slabs, and in the alternate horizontal rows oi 'the briquettes, the side edges of the structure include half briquettes la, which upon assembly of the slabs meet in pencil line seams il. Even this slight pointing operation is eliminated by constructing the edges of the slabs as indicated in Figs. VI and V'D. That is, the right-hand edge fio 0i' the slab A carries thefwhole fillet i@ for the briquettes of the adjoining edges of the two slabs A and B. The co-operating half-briquettes la are, of course, of unequal dimensions, but the structure is, manifestly, one readily to be constructed and installed` Figs. VIII and IX show still another edge construction for the slabs; itis this: Instead of including half-briquettes la in the alternate horlzontal rows of briquettes, I form in the monolithic bodies 2 of the slabs recesses il, such that when the veneer slabs are assembled the several recesses li become paired in registry, providing a pocket for the subsequent insertion of briquettes (ci. Fig. 1X). 'I'he briquettes l2 are "butterecij with mortar on their rear faces and inserted in the packets (i I-l l) thus provided. Accordingly, the iinished application of veneer, even upon close observation has a uniform reguiar and pleasing appearance.

Figs. X and XE illustrate in cross section how ,the briquettes (Ib and le) may be various-ay fashioned to decrease their weightand conserve the ceramic material of which they are formed. Additionally, the bonding betweenthe body 2 and briquettes may be in this manner increased.

-The construction of my veneer may advantageously be eected in a mold i3, in whose bottom a plurality of shallow pockets I4 is provided, so disposed with respect to one another as the briquettes are desired to 'ne in the finished product. The briquettes are placed in the pockets. the pockets being of less depth than the briquettes. Next, lthe cementitious material, suitably prepared with the desired coloring is spread over the briquettes withinthe mold, see Fig. XII, and the intervals between the briquettes are provided with molded ilets which, due to the structure of the mold terminate inwardly of the faces of the briquettes that are exposed in the finished structure. That is. the metallic reen= forced monolithic slab is applied to the one face of the expanse of briquettes, and said slab in cludes in its strelcture molded illlets which extend into the intervals between the briquettes and terminate inwardly of the opposite faces of said expanse. Conveniently, the initial application of material may terminate flush with or slightly above the top faces of' the briqnett'es in the mold, Then the metal reenibrcement 3 (Fig.

aosaeia d XIII) islaid in position, and the remainder of the mold lled, on top of the reenforcement, with a cement mix of less expensive nature. I contemplate that the last application of cementitious material may be in the form of uncolored 5 grout, but, of course. a slab 2 built completely of the colored material lies within the invention., As indicated in'dotted lines, pegs or pins I5 may be positioned in the mold, either before or after 'casting the slab, to provide the nail holes 4 al#- 10 luded to above. I claim as myinvention:

A panel for finishing the external walls'of a building comprising a. thin monolithic body o! solidied mortar including in the plane of its l5 cxpansea cancellate sheet of metallic reenforcement, a plurality of thin bricks of red clay embedded in said mortar, said red bricks being in the expanse of said monolithic body arranged in staggered relation in the same general manner that the bricks or blocks of ordinary masonry are staggered in side elevation, said thin bricks being spaced apart in the general plane of their expanse, brick pointed molded iillets cast and hardened in the spacing between said bricks and in monolithic integration with said body to constitute said panel a thin pointed brick unit, the edge of said panel being provided with recesses of a depth equal to the depth of the pointed and nished fillets cast between the bricks and'being 30 adapted in assembly for registering with the complementary recesses oi' adjoining panels to provide together pockets for the reception of whole bricks to overlie the lines of abutment oi the panels.
