TILE

no. 926,282.v

To all whom it may concern-.-

Be it known that I, WILLIAMT. NICHOLLS,

of Wellsburg, Brooke county, West Virginia,

' view showing another feature of my inven-' tion- My invention has relation to tiles, and is particularly designed to rovide a tilehaving means for more effectua ly bonding .it in cemerit, eoncrete,mortaror other setting.

In accordance with my invention, 1 pro vide thetile at one or more of its edges, preferably at all of its edges, with a series of irregular projections, which'are designed to contact with smnlar pro ections on ad acent tiles, the spaces between the projections formingopenings through which the cement or mortar which forms the joints between adj acent tiles is more efieetually bonded to that beneath or behind the tiles. In connection with the spacing feature, it is proposed to secure the maximum degree of spacing with the minimum length of projections. This is accomplished by having .the spacin projcctions on each tile arranged to abut t e correspending projections on adjacent tiles, whereby the length of each projectionis only one half of the width of the space. The advantage. of the relatively short projections is that they are less likely to become broken in storage, transportation and handling than thewidth of the space.

Another feature of .my invention consists in providing a tile having its inner or seating face formed with a series of undercut projections which are disposed at an angle so that -when seated inthe mortar or other setting they will actto resist movement of the tile in any direction.

Referring tothe drawing, tlie'numeral 2 of Figs; 1 and 2 designates rectangular tiles each ofvwhich has its edges formed of a series of irregular projections 3. These projecv tion ma be of any desired form, but should be ofsuc shape, or spaced in such an irre 'ular manner, that those upon adjacent ti es will not interfit with each other. These pro- Specification of Letters Patent.

jections form separators for'the tiles, and the openings between them form spaces through which the mortar or cement at the joints 4 -is united with and bonded to the underlying layer or bed 5. These projections may extend the full thioknessof the tile, but preferably are restricted to the inner edge'portions so that they will not be visible from the surface.

lily invention is applicable to tiles of all angular forms, thus, in'Fig. 3 I have shown it as applied to a hexagonal tile, and in Fig. 4

to a tile of triangular form. This feature is npt necessary to tiles of circular or oval form, since with such tiles sulhcient space is formed between themby reason of their shape to effect the necessary bonding.

The projections on the edges of the tiles not only serve to space the tiles for the pur-' pose above described, but they also form positive means for anchoring the tiles 1n the cement in which they are set, whereby ribs or projections, or other anchoring means,

may be dispensed with.

In Fig. 5 I have shown the invention applied to a tile of angle, form. This figure also shows a second feature of my invention,

viz., the provision of a series of undercut ribs or projections 6 on the seating faces of the tile which extend at an angle sufficient to enable them, when embedded in the mortar or other setting, to resistthemove nent of the tile in any direction. This featur'e of my invention, while particularly useful in connection with. tiles of angle form, may be used on tiles of all forms, either with or without the edge projections.

The advantages of my invention will be readily, appreciated by those skilled in the art, in view of the difiieulty which has heretofore been experienced in properly bonding tiles of angular form.

What I claim is 1. As a new article of manufacture, a tile having a finished front face and provided upon its edges with integral projections flush with the back of the tile and terminating short of the finished face, said projections being irregularly spaced and adapted to abut the projections of adjacent tiles, substantially as described.

2.. As a new article. of manufacture, a thin facing slab having a finished front face, and provided throughout. its peripheral edge with spacing projectionsset back from the front face and irregularly spaced and arfrom each other by 'means of integral abut ted projections set back from their front faces, substantially as described.

4. A- tiled surface consisting of thin facing slabs set in a plastic adhesive and separated from each other by integral, abfutted projections set back from the surface to provide intervening spaces for the adhesive and to' bond such adhesive to that'which underlies the tiles; substantially as described.

As ,a new article of manufacture, a tile having -a finished front face and provided upon its back with an oblique rib, and hav- ,ing its edges provided with spacing projections flush with the back of the tile and terminating short of-the front face thereof, said projections being irregularly spaced and adapted'to'abut the projections of adjacent tiles when set up, substantially as described. 6. As a new article of manufacture, a tile having a finished .front face, the back ofothetile being provided with a series ofobliqu'e' ribs having-corresponding longitudinal edges undercutand their outer'faces beveled from their undercutedgesto'the back face of the tile, the edges of the tile being provided with" spacing projections flush with the back of the tile and terminating short of the front v face thereof, said projections being irreg'ularly spaced and arranged to abut the projections of adjacent tiles, substantially as described.

ing slabs provided upon each edgewith spacthereof and abutting the projections of adplastic adhesive between the edges ofthe slabs andcovering and concealing the projections, substantially as described.

8. A tiled surface made up of spaced thin providedjwith spacing projections set back from the front face and abutting the spacing projections of adjacent slabs, the length of jacent slabs, substantially as described.

In testimony whereof, I havehereunto set my hand. I
