`DETROIT, MICHIGAN ENAMEL METALLIC TILE Appuaaon ma umn s1, leso. serial No. 440,595.

' The invention relates lto tiles suchias are used for facing walls in both interior and exterior finish/and it is the object of the invention to obtain a construction formed from enamelled sheet metal having many advantages over the clay product. To this end the invention consistsin the construction as hereinafter set forth. y

In the drawing:

Figure '1 is a perspective view of my improved tile;

Figure 2 is a cross section showing the tile as lald in a wall;

Figure 3 is an enlarged cross section through a portion ofl a tile and the joint between the same and adjacent tile;

Figure 4 is anenlarged perspective view' of the corner constructlon, and

Figure 5 is a plan view of a portion of the blank from which the tile isformed.

My improved construction is formed from a sheet metal blank A which is pressed 4and fashioned to form inwardly extending flanges lB on its several sides and which for a portion faces. The external surface F is smooth,

and glazed to produce the desired appearance but the internal surface G is-rough,'thereby forming a better adhesion to the cement or plaster ll. During this enamelling process it is necessary to heat the metalto a tem-v perature where' there would be a tendency for lit to sag. Such a result is, however,

venting any crackin e'ectually prevented, first by the outward bowing of the front face and second, vdue to the fact' that a-portion of the. ange B is continuous and integral `around the entire perimeter, thereby resisting any outwajrd thrust due to the sagging of the bowed portion. As a consequence, the finished tile are all of the slightly convexed form which pro-v duces a pleasing appearance in the wall.

Another' important feature of my improvement is the means which I employ for preof the enamel at the corners of the tile. uch a cracking would occur if the flanges B were separate from each other or in other words, if` the gore D were to extend completely'to the bend between the liange and the front face. With my construction, however, the fact that. the depending ange B is integral around the corners and that the enamel extends continuously over the front face and down the integral side flanges, effectually prevents the forming of any cracks at the corners.

To complete the tile, a cement or plaster core is filled in between the flanges B, being retained by Lthe obliquely converging portionsfE of said ianges. 4This core may made -either prior or during the setting of the tile i'n the wall, preferably the latter. Thus the operator may place. the plastic filling in the space betweenthe ilanges of the tile. and then place the structure against the the wall surface and retain the tile in osition. The joint I-I between adjacent ti es is' also filled with a cement and by reason of the oblique portions E, the bodyof cement between tiles is enlarged at its inner end, which` adds to its strength. The tiles may be laid against any surfacewhich is suitable for ref ceiving plaster or cement..`

What I claim as-my invention is: 4

A tile comprising a sheet metal blank gored at the corners and pressed to form a 'wall. The plastic filling will thus' knit to lfront face and'side anges, said side flanges o ,heilig of e depth greater than the depth or.

the gores to form e portion eontmuoue around the corners, presenting an side anes and around the corners for re' ceiving t e enamel finish, the gered portions of said blank being beni'l ohquely to e0nverge towards the center of the tile to foriumA Yinclined triangular-shaped openings et the .corners, and said sheet metal structure having aA vitreous enamel surface 'outside and inside.

In testimony whereof I ami my signature;
