-4 Claims. (Cl. 'Z2-23) My invention relates to a wall veneer, and While primarily intended for veneering the outer sides of the walls of a building structure and embodying a facing simulating laidbrick, it will d be obvious that the facing may also be constructed to resemble tile or any other analogous facings to adapt' same for any other purposes wherein it is found to be applicable.

Important objects of the invention are to l@ provide a wall veneer of the character described, which will exactly simulate a wall constructed from brick laid in the usual manner, which is constructed in the form of intertting slabs of convenient size to permit same to be handled and w attached by a single person, which is absolutely weather-proof and requiresl no mortar or other sealing agent between adjacent slabs after the latter are secured in their relative positions, which includes a sheet metal backing plate em- M bodying novel means for casting the facing thereto, and which provides an air' space between the veneer and the wall structure.

Further objects of the invention are to provide a device of the class stated, which is simple M in its construction and arrangement, strong, durable and eiiicient in its use, nre-proof, attractive in appearance, comparatively light in weight, and inexpensive to manufacture, attach and maintain.

ab With the foregoing and other objects in view which will appear as the description proceeds, the invention resides lin the novel construction, combination and arrangement of parts therein specifically described and illustrated in the ac- 35 companying drawing, but it is to be understood that the latter is merely illustrative of an embodiment of the invention, and that the actual needs of practice and manufacture may require certain mechanical variations from the embodi- @0 ment shown. It is, therefore, not intended to limit the invention to the disclosure herein illustrated, but rather to dene such limitations to the scope of the' claims hereunto appended.

Y. In the drawing wherein like numerals of reference designate corresponding parts throughout the several views:-

Figure 1 is a fragmentary front elevational view of a building wall to which my improved veneer m has been partially applied.

Figure 2 is a front view of the backing plate.

embodied in the present invention.

Figure 3 is a full size end view thereof. Figure 4 is a full sized transverse cross secl tional view illustrating the attachment of the veneer with a building wall with portion thereof being broken away.

Figures 5 and 6 are,lrespectively, perspective views of corner units constructed in accordance with the invention.

Referring in detail to the drawing 1 denotes an entire unit or slab, a plurality of which com-I prise the veneering structure. The slabs 1 are preferably uniform in size and construction, and each includes a backing plate 2 and a facing 3.

The backing plate 2 is oblong and rectangular- 1y shaped and may be constructed from any suitable sheet material, preferably thin galvanized sheet metal, or other durable sheetmetal that is not susceptible to rusting or corrosion.

'I'he backing plate 2 extends on an even plane, except that it is provided with a back-set top edge margin 4 and a back-set end edge marginA 5. 'I'he top and end edge margins 4 and 5 are set back from the plane of the front surface of the backing plate 2 a distance exactly commensurate to the thickness of the sheet metal from which the backing plate2 is constructed. The backset corner 6, adjoining the top and end edge margins 4 and 5, is set back a distance equalling 80 twice the thickness of the sheet metal employed.

The top edge margin 4, of each of the'slabs 1, is formed with a longitudinally extending ridge or rib '7, which is disposed on the rear side thereof, and forms a groove 8 on the front 95 side of the back-set edge margin 4. The rib 'l is spaced from the normal end 9 of the edge margin 4 and the bottom of the groove 8 opens onto and is disposed on the plane of the doubly back-set corner 6. 90

A plurality of flared burrs 10 are punched directly from the backing plate 2. The burrs 10 project forwardly and are spread in spaced relation over the entire area of the backing plate 2 excepting the back- set edge margins 4 and 5 95 thereof.

The facing 3 covers the entire area of the front side of the backing plate 2 with the exception of the back- set edge margins 4 and 5. The facing 3 comprises any suitable weather and 100 moisture proof cementitious material, namely, stucco or analogous materials, and is applied in its plastic form to the backing plate 2. When so applied, the burrs 10 will be embedded in the facing 3, whereby the latter, upon harden- 105 ing, will. be permanently, rigidly, and xedly secured to the associated backing plate 2. Each slab 1 is completed as a unit at the place of manufacture prior to its attachment to the building structure in the manner to be described. 1.1

Tle front of the facing 3 is cast or shaped and colored to resemble brick 11 and interposed mory tar 12. As illustrated in Figure 1, three imitation bricks 11 are preferably carried by each of the slabs 1 and are longitudinally aligned relatively to each other. The bottom of each of the bricks 11 is exactly flush with thelower normal edge 13 of the backing plate 2. The imitation.

back set edge margins 4 and 5, is preferably rst covered with the plastic material repretiers.

senting the imitation mortar 12, after 4which the material, simulatingthe brick 11, is cast in position directly onto the mortar 12, to provide a composite structure with the latter. The brick 11 project a suitable distance from the plane of the surface of the mortar 12, and are preferably of conventional length and thickness. This construction resembles brick laid with raked joints, but it is apparent that the arrangement may be varied to provide any other joint desired.

In securing the slabs 1 to a wall structure, indicated at 14, the rst tier is arranged in longitudinal alignment along the lower end of the wall structure 14. The normal end of each backing plate 2 overlaps the back-set end margin 5 of the adjacent backing plate 2, thereby providing a juncture between the abutting ends of adjacent slabs thatis barely perceptible, as clearly illustrated at 15, in Figure 1. The normal end 9 of each backing edge margin 4 seats in the doubly back-set corner 6 of the adjacent backing plate, whereby the top edge margins 4 of the backing plates in the longitudinally aligned slabs, will be disposed on an even plane.

The formation of the back-set top margin 4 in conjunction with the rib. 7, will space the backing plate of each slab 1 from the surface of the wall structure 14 providing the obvious advantages of a desired air space 16 between the latter and the veneering.

Each of the slabs 1 issecured in its relative position by means of any suitable fastening devices, preferably, nails 17, which extendv through apertures 18, provided therefor in the rib '7, and are driven into the wall structure 14. The heads of the nails 17 seat in the groove 8 and do not project from they latter and consequently will not interfere with the overlapping engagement of the superimposed slabs.

Each subsequent tier of slabs 1 is likewise arranged and securedv in longitudinal alignment, and the lower normal edge 13 of each backing plate overlaps the back-set top edge margin 4 of the slab or slabs disposed directly therebeneath, and provides a juncture between adjacent slab tiers that is not discernible, as indicated at 19. The slabs 1 of each tier are preferably staggered relatively to the slabs of adjacent tiers to prevent the meeting of end abutments of the slabs of adjacent tiers.

Varying corner slabs 20 and 21 are provided to establish the desired staggered relation of each tier of slabs 1 with respect to the adjacent The corner slabs 20 and 21 each embody a backing plate 22, which is of a construction identical to that described relatively tothe backing plate 2 of the slabs l, except, of course, that it is shaped to provide portions extending at right angles to each other to fit around the corners of the walls of the building structure.

It will here be noted that the present invention provides a veneering embodying a sheet metal backing in the form of backing plates 2, which latter overlappingly engage each other and cover the entire area of the wall structure 14. The construction and arrangement of the backing plates' 2 together with the facing 3 carried by the latter, provides a weather and moistureproof veneering in which the junctures of adjacent slabs need not be nished with a sealing agent after the slabs have been attached in position.

While illustrating and describing the backing plate 2 as, being provided with a plurality of burrs 10 for securing the lfacing 3 thereto, it is apparent that the backing plates 2 may be formed with various other types of engaging devices for rigidly securing the facing 3 in position. Further, pockets may be formed into the top edge margins 4 of the backing plates 2 for spacing the latter from the wall structure 14 and for providing recesses for the fastening of the nail heads instead of the groove 8 as shown. However, the formation of the latter provides the rib 7, which reenforces the backing plate, l

besides-serving for the purposes set forth.

It is evident that, during the attachment of the slabs 1 to a building wall any suitable sealing material, as paint, tar products, or the like, may if desired, be spread on the overlapping portions of adjacent slabs, but such sealing material is not deemed essential for preventing the entrance of moisture into the joints of the adjacent slabs.

The facing 3 may be arranged and conl structed as shown and described, or in anyV other adequate ways to meet the conditions encountered, and in all instances a weather-proof and attractive wall veneer will be produced, in

-which the resemblance to laid brick is so marked that it is almost impossible to descern the difference.

What I claim is:

1. A veneer slab of the character described, comprising a sheet metal backing plate, a facing of concretive composition material secured to front of said backing plate and covering the entire area of the latter excepting the top edge marginand an end edge margin, said top and end edge margins being set back relatively to the plane of the covered portion of said backing plate.

2. A veneer slab of the character described, comprising a sheet metal backing plate, a facing of concretive composition material secured to the front of said backing plate and covering the entire area of the latter excepting the top edge marginA and an end edge margin, said top and end edge margins being set back relatively to the planeof the covered portion of said backing plate, the adjoining corner of said top and edge margins being set back with respect to the plane of the latter.

3. In combination, a wall veneer slab of the character described, comprising a sheet metal backing plate, a facing of concretive composition material carried on the front of said backing plate, means formed on said backing plate for securing said facing to the latter, said facing covering the entire front area of said 4. A veneer slab of the character described comprising, a backing plate, a facing of concretive composition material secured to the front of said backing plate and covering the entire area of the latter excepting rthe top edge margin and an end edge margin, said top and end edge margins being set back relatively to the plane of the covered portion of said backing plate.
