HARRY HAUGH, OF ANDERSON, INDIANA.

TILE.

Specification of Letters Patent.

Patented Dec. 3, 1907'.

Application filed October 28, 1905. Serial No. 284.831.

To all whom it may concern:

Be it known that I, HARRY HAUGH, a citi- Zen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Tiles, of which the following is a specification.

Plain backed tile are difficult to set so as to adhere efficiently to walls, especially where used as wainscoting. It has frequently been proposed to make such tile with keyed or dove-tail grooved backs, for the purpose of causing them to adhere better. When dovetail shaped grooves are formed in the central portions of the backs of tiles, however, there is a difliculty in embedding them properly in the cement because of the tendency to cause air pockets into which the cement cannot be folrced by the ordinary methods of setting ti e.

It is the object of my present invention to provide a tile with a back which shall have the keyed or dove-tail grooved form, and in which the disadvantage stated shall not be present. I have therefore formed such tile with tapered half grooves, which runalong the edges, and which are undercut somewhat at the inner side. Such tile can be easily put in place in such a way as to force out the air, by simply placing them against the wall and beating them into the cement thereby surely filling the tapered undercut groove formed by the adjacent edges of two tiles. Any air which may be present will escape through the interstices between the edges of the tiles without difficulty, such interstices being afterwards filled in the finishing of the work.

The accompanying drawings illustrate a tile embodying my invention.

Figure 1 is a perspective view of such a tile; Fig. 2 an under side or plan view of one tile and fragments of adjacent tile, and Fig. 3 a transverse sectional view at the point indicated by the dotted line 3 3 in Fig. 2.

Said tile, 21, as shown, has (in my preferred form) shallow open ribs and grooves extending across the back until the edge is nearly reachedthere being at the edges the underhung or cut away half-grooves or dovetails, 23, which, as best shown in Fig. 3, when the tile are assembled, form dovetailed connections with cement or plaster, 25.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is,

1. A tile having a half dove-tail groove at each edge tapered and wider at one end than the other, the wide ends of the two grooves being arranged at the same end of the tile and the side of each groove being straight and continuous from one end to the other.

2. A tile having a half dove-tail tapered groove at each edge the side thereof being straight and continuous from one end to the other, and a series of straight open grooves between the two half dove-tail tapered grooves.

3. A tile having a half dove-tail tapered B. V. HAUGH, GEORGE LILLY.
