1 Claim.

The invention relates to tile mountings and has reference more particularly to the mounting of tile elements upon an appropriate surface, to produce a tile panel or unit which can be employed for tiling work.

Heretofore the greatest objection encountered in the tiling of surfaces such as floors, walls, etc., has been the excessive cost of labor necessary for laying the tiles in proportion to the cost of the material used. The actual embedding of. the tiles in a freshly poured cement surface, the aligning of the tiles with each other and the spacing of them so that the tiled surface as a whole presents a neat appearance is of course an exacting task and requires skilled labor.

An object of the present invention therefore is to provide suitable supporting surfaces adapted to have tiles previously mounted thereon, a plurality of which surfaces can be secured to a support thus presenting a neatly tiled area which will reduce the labor cost in tilingthe same to a minimum.

Another object of the invention is to provide an appropriate surface upon which tile elements can be mounted by being cast upon the surface and interlocked thereon, which surfaces will afford a unit for tiling any area such as a wall,

ceiling or the like.

A further object is to provide an improved method of forming a tile panel.

With these and various other objects in view, the'invention consists of certain novel features of operation, as will be more fully described and particularly pointed out in the specification,

' drawings and claim appended hereto;

' In the drawings- Figure l is-a perspective view of a section of a urf ce showing some tiles in place and others removed.

Figure 2 is a sectional view taken on line 2-2.

ployed in casting the surfaces showing the tile elements in place.

Figure '7 is a sectional view taken substantially through the middle of the device as disclosed in Figure 6.

The surfaces, slabs or foundations it having the tile elements I! cast thereon are preferably formed of plaster, such as is used in interior plastering work. This composition consists principally of lime and sand, which when finally set forms a hard durable block, having the advantage of lightness in proportion to its bulk. Cementmortars may also be used and are in fact more desirable when an extremely hard block or slab is required and where excessive weight is not a disadvantage. The plaster slab is found desirable in tiling a wall, while the heavier slab may be used for floors, etc., which in addition to being subjected to constant wear, would also have to support a moderate weight.

The tile elements l2 as shown in Figure 3are formed preferably by being stamped from a sheet of metal and comprise a flat face, having side portions or marginal flanges it provided with tabs or tangs IS. The tabs are bent down as shown and with the tiles in this inverted position, the plaster is poured over them to a suflicient thickness according to the specific use the resulting slab orpanel is to be put. The tabs are in this manner embedded in the plaster and after hardeningor final set has taken place, the tile elements are securely locked to the surface of the slab. The same may be cast having a large number oftile elements secured thereto or of a size to accommodate the four tile shown in Figure 4.

The invention, it is to be understood, is not necessarily limited to the use of. any special size of tile, since for some work a fairly large size tile may be needed, which would require a fairly large slab for the purposes of the invention, while for another character of tiling work a smaller size of tile and correspondingly smaller slab could be used. This latter size of slab has been found in actual use to give very good results when employed for floors, as such surfaces are subjected to moderate weight .and the smaller size has little or no tendency to crack due to this weight as would be the result with the larger size. Accordingly the form of. slab shown in Figure 1 I finds more extensive use in the tiling of walls.

It has also beenv found desirable to afford some suitable locking means for the slabs to help lock the same to their supporting walls or floors, as the case may be, and for this purpose the slabs may be provided with a longitudinally extending slot it, which is made dove-tail in shape. This recess interlocks with the cement when the slabs are laid or embedded therein, thus forming additional means for holding the slabs in place. I

Referring to Figure 6, the arrangement used elements as I in casting the plaster surfaces, consists merely of a box structure having a bottom 20 and sides 22. Upon the bottom is formed protuberances II, which are spaced from each other a distance equal to the width of the tile elements to be used. The protuberances run transverse and longitudinally of the box and divide the bottom into squares, into which are placed the tile elements l2 with the tabs l8 bent over as shown. With the elements so spaced, the plaster or mortar is then poured until the desired thickness of slab is secured. After the final set and hardening has taken place, the cast slab can be removed. Due to the raised protuberances the tile elements are correctly spaced, not only upon the surface of the slab, but also in relation to each other and in addition grooves 26 are formed between the elements I 2 to give them the appearance of being raised from the surface of the slab. This spacing is carried out when the slabs are located adjacent to each other by making the distance from the edges of the slab to the tile elements just onehalf the full tile spacing. As shown in Figure 5 the various surfaces with the elements l2 cast thereon are embedded in mortar or plaster 20 so that all are in close abutting relation. In finishing on the tiling work, some of the mortar is spread between the tiles to conceal the abutting edges ofthe surfaces. This is generally known as pointing up, the result of which is to give to v any floor or wall, covered in the manner as described, the appearance of individually laid tiles.

The system of tiling disclosed in the Haines Patents Nos. 1,594,614 and 1,704,537 is particularly valuable in tiling relatively small irregular surfaces, such as occur, for instance. in bathrooms and kitchens, because the foundation sheet can fit around projecting portions, .such as window frames, window sills, door frames, medicine cabinets, bath tubs, etc., and secured in place upon the wall, and the tiles thereafter applied to the foundation sheet.

There is, however, a large field in which the method of tiling herein disclosed may be advantageously employed, that is to say, jobs where relatively large continuous or unbroken surfaces occur, as in corridors, exterior walls, subway and Here it is possible to employ rected to the production of such tiled panels as 20 articles of manufacture.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration and not limitation, as various and other forms of the device will of course be apparent to in the art without departing from the spirit of the invention or the scope of the claim.

I claim:

The process of producing a tiled unit consisting of a foundation having the face thereof covered with a multiplicity of tiles, each of the tiles having tangs extending into the foundation, which consists in supporting the multiplicity of tiles in inverted position and properly spaced from .one another, and applying the foundation to said 35 supported series of tiles whereby the tangs are engaged with the foundation.

(Seal) those skilled 25 printed specification of in casting the plaster surfaces, consists merely of a box structure having a bottom 20 and sides 22. Upon the bottom is formed protuberances II, which are spaced from each other a distance equal to the width of the tile elements to be used. The protuberances run transverse and longitudinally of the box and divide the bottom into squares, into which are placed the tile elements l2 with the tabs l8 bent over as shown. With the elements so spaced, the plaster or mortar is then poured until the desired thickness of slab is secured. After the final set and hardening has taken place, the cast slab can be removed. Due to the raised protuberances the tile elements are correctly spaced, not only upon the surface of the slab, but also in relation to each other and in addition grooves 26 are formed between the elements I 2 to give them the appearance of being raised from the surface of the slab. This spacing is carried out when the slabs are located adjacent to each other by making the distance from the edges of the slab to the tile elements just onehalf the full tile spacing. As shown in Figure 5 the various surfaces with the elements l2 cast thereon are embedded in mortar or plaster 20 so that all are in close abutting relation. In finishing on the tiling work, some of the mortar is spread between the tiles to conceal the abutting edges ofthe surfaces. This is generally known as pointing up, the result of which is to give to v any floor or wall, covered in the manner as described, the appearance of individually laid tiles.
