COVERING

Application, filed March. 31, 1928. Serial No. 266,440.

The invention relates to a covering for Avails, floors, etc., constituting a simulation of tile or the like, and it may represent glazed or unglazed tile, ceramic tile, glazed or un₅ glazed brick, mosaic, stone, marble, terra cotta, etc., and hence, even though such expressions as “tiles.” “tile simulations,” etc., may, be hereinafter used, it is to be understood that I am not restricted to the simula10 tion of actual tiles.

The invention further relates to a covering in which plastic-receiving and retaining grooves are.provided between the tile simulations to be filled with pointing material after la application of the covering, thus not only enhancing. appearance, but hiding all nails which may be used in attaching the covering, as well as obscuring any seams.

It is one object of the invention to provide 20 the plastic-receiving and retaining grooves of such form that they are much wider near their inner closed sides, than at their open sides. Thus, not only will the plastic pointing material be effectively held in place with25 in the grooves, but a much larger body 'of such pointing material may be used, thereby retarding the drying out of such pointing material and increasing its strength accordingly.

so A further object of the invention is to provide a covering of rigid nature, in which the tile -₁ simulations may be. advantageously formed as separate units from a rigid backing board and cemented or otherwise secured 35 to this board at the factory. Under this method, the shape, color or shade and other characteristics of the., simulations, may be varied on the same backing board, producing effects obtainable in no other manner except with actual ceramic tiles. The rigidity, of structure permits the device to be secured directly to spaced studs, rafters or oilier spaced members without the necessity of any continuous backing surface. However, it 45 mav be cemented against a surface such as a floor or a plaster-covered or other wall if desired, in which connection, a further aim is to provide novel means whereby any surplus of cement or the like used for securing

SO the covering to the surface, may be received in a multiplicity of sockets formed in the reverse side of the covering, the cement or the. like so received, serving also to establish effective keys between the covering and. the surface over which it is secured. 55

Yet another aim is to provide a construction in which the above named sockets are formed by openings passing entirely through the backing sheet, so that they not only provide the sockets with the advantages above go pointed out, but also serve to receive part of the cement by which the tile simulations are secured to the backing, thus assisting in giving an unusually strong anchorage for this cement. G5

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings. 70

Fig. T is an elevation showing a portion of the Avail covering secured to studs.

Fig. 2 is an enlarged horizontal sectional vieAA^ on line 2—-2 of Fig. 1.

Fig. 3 is a similar ifiew on line 3—3 of Fig. 75 1 but shoAving the pointing material in place.

Fig. 4 is a vieiv similar to Fig. 3 but showing a modified form of construction in which the back of the covering is formed with sockets. SO

Fig. 5 is a fragmentary rear elevation of the construction shoAvn in Fig. 4.

In the draAvings above briefly, described, the numeral 6 denotes a. substantially rigid backing sheet or board formed of any suita- 8E ble composition. Secured upon the front side of this backing sheet or board, for instance by a layer of appropriate cement 7, are the tile simulations 8 Avhich are also of appropriate composition. The edges 9 of VO the simulations 8, are spaced apart to provide plastic receiving and retaining grooves 10 for an appropriate pointing material, and said edges are so shaped (preferably beveled) as to give a greater width to the OS inner closed sides of the grooA^res, than to their outer open sides. These grooves are preferably given a dove-tail formation which insures that the plastic pointing material 11 shall not fall therefrom. This construction 190

From the construction shown and described, excellent results may be obtained and the details which I have herein disclosed are preferably followed. However, within, the scope of the invention as claimed, variations ₇₀may be made. For instance, although the back board or sheet 6 is preferably rigid, it will be obvious that the grooves 10, shaped as described, would possess the same advantages even if said back board or sheet were 75 of more or less flexible nature. Similarly, the sockets or openings 12 would possess virtually the same functions if the backing board or sheet 6 were of a nature other than rigid. Hence, I wish to be considered as contem- so plating such variations, within the scope of the claimed invention. Moreover, I wish it understood that I am not restricted to specific materials, dimensions, ornamentation, etc.
