WALL-TILE.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application filed March 5, 1909. Serial No. 481,332. r

To all whom it may concern:

Be it known that I, FRANK X. \VILLE, a

citizen of the United States, residing at Spokane, in the county of, Spokane and State of l/Vashingtomhave invented an Improvement in IValLTiles, of Whichthe following is a specification.

My invention relates to improvements in tile constructions, and consists in the parts cement which forms the retaining medium.

hereinafter described and claimed.

The main object of) my invention is to provide wall tile with novel securing de- A further object of my invention is to provlde a novel retaining means which 0bviates certa n ob ections common to the retaining means. in ordinary use.

My invention is illustrated in the accompanying drawings, in which- Figure l is a perspective view of a portion of tile provided with my improved retaining devices. Fig. 2 is a transverse section showing the tile of Fig. 1 applied to the cement facing. Fig. '3 is a view showing a modified form of the retaining devices,

and Fig. 4 is a section showing the tile in Fig. 3 as applied to the cement facing.

Referring now to Fig. 1, I have shown therein a portion of a piece of tile A. The tile may be of any approved composition. On the rear, side of the-tile I arrange a series of longitudinal integral projections Br These projections are inclined at an angle to the main; body portion, as clearly shown in Fig. 2. Adjacent projections are separated by spaces C which are approximately of the same width-as the projections themselves, although these spaces may vary within limits.

In Fig. 2 I have shown the tile in its ce-' ment setting. It will be observed that the inclined faces 6 tend to engage the parts of the .cement facing D which areimmediately adjacent, thereby preventing the separation In applying the tile the workman presses the block thereby forcing the grips or projections B into the plastic cement, which immediately fills the 5 spaces C between adjacent grips. It will be observed that the body portion of the tile cannot come into close contact with the outer wall until the projections have been pushed into the plastic cement. Moreover, the spaces C must also be filled before the bodyportion of the tile is up against the wall. There is no danger, therefore, of any ofthe spaces being empty. When the cement hardens the tile is securely fastened to the face of the wall by the engagement of the inclined portions of the projections, in the manner already described.

In Figs. 3 and 4: I have shown a tile provided with projections B and B In this form the projections on one half of the tile are in opposite directions from those onthe other half. This gives a grip on both halves of the tile, on opposite sides of the projections.

I am aware that tile retaining devices have been used in which grooves are made in the face of the tile, but there is't'his objection which I have overcome in providing the projecting grips instead of grooves that, in the'case of the grooves the workman does not know whether the cement has entered the groove, even when the tile is up to the face of'the wall. In many cases the grooves contain air which will prevent the entrance of the plastic cement and thereby defeat the purpose of the retaining devices. In my construction, however, no such contingency ispossible because the projections must be forced into the cement before the main body of the tile can come into engagement with the wall.

I claim:

As an article of manufacture a wall tile .comprising" a main body portion having two sets of strips projecting from one side integral therewithone set of said strips being inclined at .an angle in one direction and the other st ips being inclined at an angle in the opposite direction, said stripsv being of uniform width in cross section,

and adjacentstrips in the set being separated by a space the same width' as the strips themselves.
