6 Claims.

This invention relates to composition building elements for interior and exterior construction and has for the primary object, the provision of a device which will provide eilcient insulation against Weather elements and a resistance against re and protection from vermin and germs and a deadener of sound.

Another object of this invention is the provision of vchemically treated bodies or slabs which will possess insulating qualities and be capable of withstanding various kinds of strains or stresses and so constructed as to have intertting connections With each other when assembled.

A further object of this invention is the provision of facings for the slabs to provide attractive and artistic appearance thereto and a novel method of securing the facings and slabs together to provide them of substantial integral construction to render them capable of withstanding severe wear and to meet all building requirements and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a perspective view illustrating a brick employed as a facing element in one form of my invention.

Referring in detail to the drawings, the numeral I indicates a slab or body constructed from'long, tough, fibrous material, such as wood fibre, grass, weeds, and other similar materials. The selected material is preferably seasoned and chemically treated to resist re and pressed into a solid mass to provide the slab or body I. One face of the slab or body is coated with a solution of magnesium chloride and then covered with a coat of thin cement having the consistency of cream. The slab or body is capable of resisting fire, and insulation against heat or cold and dampness and will be non-conductive of noises and non-penetrative by vermin and disease germs. The slab or body may be of varying dimensions, preferably of a thickness ranging from one half inch to one inch while the other dimensions thereof may remain standard which is conventional in building construction.

A facing 2 is provided with the slab or body I and is in the form of individual bricks 3. The bricks 3 are of a conventional dimension except for their thickness as shown in Figure 1. The thickness being much less than an ordinary brick.

A frame 4 of substantially the size of the slab or body is divided by a series of partitions 5 and 6. The partitions being so arranged that when they receive the bricks, the latter will resemble a brick wall of ordinary formation. The frame 4 rests upon a plate 'l to retain the bricks within the frame and project slightly beyond one face of said frame and are coated with a solution of magnesium chloride over which is placed a coating of thin cement having a creamy consistency. The slab or body I is then applied to the bricks as shown in Figure 5 with the treated face thereof next to the treated faces ofthe bricks. The slab or body resting upon the bricks within the frame 4 is then placed in a hydraulic press and subjected to a desired pressure causing the cement to be forced deep into the voids of both the body or slab and the bricks causing said parts to become substantially of integral construction.

The body or slab has its side edges cut away to provide flanges B which anges of slabs or bodies l'ns when assembled in wall formation will have overlapping relation. The ends of the slab or body are cut away to provide spaced tenons 9 and notches IIJ. The walls of the notchesand edges of the tenons are bevelled so that when slabs or bodies are assembled in wall formation the tenons will t within the notches establishing interlocking connections between said bodies or slabs. Due to the connections of the slabs or bodies with each other when in wall formation waterproof or leakproof connection is established therebetween and the assembled wall from its outer face will have the appearance of an ordinary brick wall.

Anchoring plates II are suitably fastened to the studding of the wall construction and have struck out therefrom a series of tines I2 which may be driven into the slabs or bodies thus effectively anchoring the latter to the studding' of the wall construction.

Referring to my modified form of invention as shown in Figures 9 to 1-1 inclusive, the bricks constituting the facing have formed thereon tapered or substantially conical shaped lugs I3 received within cylindrical pockets I4 formed within the slab or body and when the slab or body and the bricks are subjected to pressure, the material of the slab or body will close in and about the lugs I3 thereby firmly anchoring the face bricks to the slab or body as shown in Figure l1.

Referring to'Figure 12 the bricks are provided with recesses i3' so that when the slab or body is applied, the material thereof will enter ilie recesses forming lugs I6 or bonds therebetween.

Referring to Figures 13 to 15 inclusive, a modified form of my invention is disclosed and which consists of a facing I5 secured to a slab or body i6 similar in construction to the slab or body I by the method heretofore set forth. The facing I5 is constructed from cement or similar material and has its outer faceV grooved and lined, as shown at I'i and E8 to represent shingles so that the device may be employed in wall or roofing construction wherein it is desired that the device L have a eliingied appearance.

Referring to Figures 16 to 22 inclusive, a modicd form of my invention is disclosed in which a facing I9 has the appearance and the advantages of tile roofing and the body or slab 20 is When the facing I9 representing the tile roofing 5 -is assembled on the body or slab 20 by the method disclosed by Figures 9 to ll and heretofore described, the tile shingles will have overlapping relation, forming ridges and valleys. Certain of the shingles being convex as shown at 24. The other shingles are concave as shown at 25.

Referring to Figure 23, tile shingles 24' of the concaved and convexed types are provided on their inner faces with recesses and a filler 25 is placed between the same and the slab or body. The material of the ller is of a fibrous nature mixed with a binder so as to adhere to the shingles and slab. The material entering the recesses of the shingles is clearly shown in the drawings.

Referring to Figures 24 to 26 inclusive a facing' 26 is provided and secured to the body or slab 21 as heretofore described and represents clapboarding. The facing 2B being constructed of cement or similar material.

Referring to Figures 27 to 29 inclusive, the

facing 28 is secured to a slab or body 29 in the heretofore described method and is constructed of cement which is grooved and its outer face highly polished to represent tiling for interior construction.

Referring to Figures 30 and 31, the body 3D has a facing 3I secured thereto in the method heretofore described and is constructed from plastic or similar material, the surface of which may have a roughened appearance or a white coating so that when assembled in wall construction will have the appearance of plaster walls for bination and arrangement of parts may be made4 without departing from the spirit and scope of my invention, as claimed.

Having thus described my invention, what I claim is:

An article of manufacture comprising, a slab composed of shredded fibrous material treated to render the same ilreproof and having a facing composed of spaced elements of refractory material and a coating of magnesium chloride covered by a coating of cement, said coatings acting to secure said refractory facing elements and slab together.

5. An article of manufacture comprising, a slab of refractory material, a facing for the slab composed of spaced elements of refractory material cemented by means including magnesium chloride, two opposite sides of the article being oppositely rabbeted, and two other opposite sides being recessed to sealingly complementally fit corresponding recessed sides of another article, to form a sealed wall, or lfa'cing for a wall.

6.
