Improvements in Floor and Wall Tiles; and The tile A (shown inFigs. 1 to 4, inclusive) I do declare the following to be a full, clear, may be of any desired outline or size. In its and exact description of the invention, such under side is a cavity orrecess B, the shape aswilienable others skilledin theart towhich of which is preferably circular, as shown.

The retion.

i My invention relates to ornamentaltiles for running across the bottom of the tile and out floors and walls. Such tiles are usually made to the sides thereof. These grooves are rather with several shallow grooves in the back, but shallw at their outer ends, but preferably these grooves have no positive hold on theceincrease in depth as they approach the recess merit in which the tile is set, merely affording until they are of the same depth there as 20 a larger adhesive surface between the tile and at their points of intersection therewith, as

the cement. It has been proposed to make clearly shown in Fig. 3. It will be seen that these grooves undercut or dovetail in crossthose portions b of the walls of therecess section, so as to afford a key with the cement which lie between the grooves G are comparand give the tile a strong and positive hold atively thick, so as to have considerab1e75 25 thereon; but such undercut grooves are difstrength. Vixen such a tile as this is pressed ficult to make, and their thin sharp edges are into the cement, the recess will be filled with very liable to become broken 0E, thereby dethe plastic oement,and the air in the recess can stroyiug their holding effect. To remedy this, escape through the grooves G at each side of it has been proposed to make one or more the tile or at one side in case one edge of the 2o undercut recesses or sockets in place of the tile enters the cement before the other. In

My invention aims to with the body of cement into which the tile overcome these difficulties by providing the is laid. In every case the cement engages tile with a concealed recess having undercut with the wider upper part of the recess, and walls and intersected by transverse grooves thereby makes a strong key which holds the running out to the edges of the tile, one or tile firmly in place. 9o 0 more of the groovesbeiug deep enough to af- In the modification shown in Figs. 7 to 11 ford a free escape for'the air in the recess the tile has two rather deep channels D runwhen the tile is pressed intothe-cement. ning across its bottom face, with ashallower.

has walls which are upright at their lower part b and slope outwardly at their upper part b, thus making the upper portion of the recess larger than the lower portion. This enlarged chamber or cavity aflfords ample opportunity for the cement to enter and make a strong key with the tile. The grooves C D D are formed by ribs on the lower die of the tilepress. The recesses are made by placing on said die a former of combustible material. The tile-forming material is then deposited upon and around said former and lhe tile is pressed, embedding the former When the'tile is fired, the former will slowly char and volatilize at the high temperature to which the tile is subjected, thus leaving the recess clear and free from debris;

The formers E E E must be made of some material which will not burn with a fierce flame or intense heat, since otherwise they would crack and ruin the tile. tial also that this material shall be non-absorbent of moisture, since otherwise it would soak up moisture from the damp clay or d nst The former shown in Fig. 5 isto be placed one cylindrical support integral with or attached to the die of the tile-press and located at the intersection of the ribs which form the grooves. The former shown in Fig. 6 is to be located at the same place in the die, but its lower cylindrical portion e takes the place It is essenof the support used with the other former. In each case the shape of the recess is the same-that is, it has a cylindrical lower portion and an enlarged flaring upper portion.

Having thus described my invention,what I claim is-- 1. 'Afioor and wall tile, havingin its under side arecess withundercut walls, and grooves intersecting said recess and running to the sides of the tile.

2. A door and wall tile, having in its under sidearecess with undercut walls, and grooves intersecting said recess, one or more of which are as deep as the recess at the point where they intersect it.

3. A floor and wall tile, having in its under side a recess with undercut walls,and grooves intersecting said recess, which are deeper at the inner end than at the outer.

4. A floorand wall tile, having in its under side a recess with undercut walls, and grooves running from said recess to the sides of the tile, said recess having the lower portion of its walls upright and the upper portion sloping outwardly to form an enlargementof the recess at its upper part.

In testimony whereof I 'aflix my signature in presence of two witnesses.

ALFRED PLANT.
