ROOFING-TILE.

To all whom it may concern:

Be it known that I, JOHN M. MARTIN", a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in RoofingTiles,-of which the following is a specification. improvements in roofing tiles.

This invention relates to new and useful The invention has particularly to do with plastic tiles and a sealed and lockedjoint therefor.

In carrying out the invention I provide each tile with a locking groove or seat along one edge and an overhanging bead or flange carrying a depending rib adapted to fit therein by a mortar, such as cement. The groove and'rib are both wider along their lower faces, thus giving the effect of a dove tail joint. The tiles are also provided with a transverse water'tight joint where they overlap, thus preventing water backing up between the tiles.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure 1 is an isometric view of a plurality of tiles forming part of a roof.

Fig. 2 is a longitudinal sectional view on the line 22 of Fig.1,

Fig. 3 is an isometric view showing a modified form,

Fig. 4 is an isometric view of still another form of tile, and

Fig. 5 is a longitudinal sectional view of the same on the line 55 of Fig. 4.

In the drawings the numeral 10 designates a plastic roofing tile having a looking groove 11 along one edge, the groove being wider along its lower face. Along its other edge the tile has an overhanging flange 12 with a depending rib 13 adapted to enter the groove 11.

In constructing a roof of the said tile the rib is seated in the groove in cement or mortar, the latter locking same. The groove and rib being wider along their lower faces give the effect of a dovetail joint. In order that the tiles may be laid in break-joint relation a recess 14 in the under surface of the tile at the center of the lower end of the latter raises the rounded flange of the tile in the next lower course; thereby providing a close joint.

filled with cement or mortar and the tile of the next higher course is'laid'thereon thus forming a water-tight joint where the two tiles lap which would prevent water from backing up between the said tiles.

In Fig. 3 a modified form of the tile is shown, wherein the tile 10 has a sinuous design and the flange 12 is so constructed'as to form a part of the sinuous curve of the design, and is received ina recess 16 in the adjacent tile. The same locking means is employed however, as in Fig. 1, comprising a groove 11 and a rib 13 depending from the flange, the groove and rib being wider along their lower faces and being locked together with cement or mortar, and giving the effect of a dove-tail joint.

In'Fig. 4 another modification of the tile is shown wherein the tile 10 is of a flat design and the flange 12 is flush with the surface of the tile, being received in a recess 16 in the adjoining tile. The locking means comprising a groove 11 and a rib 13 depending from the flange, both groove and rib being wider along their lower faces and the rib being seated in the groove in cement or mortar, is also employed in this design. Transverse' slots 15 adjacent the top of the tile are employed, and form a watertight joint by being filled with cement and the tile of the next higher course being lapped over the said slots, as shown in detail by Fig. 5.

It will be noted that a roofing tile constructed in accordance with this invention will make an extremely substantial and water-tight construction and may be quickly and easily laid.

It'is pointed out that the lock joint is a very important feature of this invention and it is essential to its success that the dove-tailjoint effect be had.

It is further pointed out that the construction of the groove and rib each having a cor responding side inclined and the other side perpendicular so as to tend to draw the tiles together, is very important as it makes for a closer assemblage of the tiles.

What I claim is:

1. A roofing structure comprising, a plurality of tiles arranged in courses, each tile being provided near one edge with a groove which increases in width downwardly and at its opposite edge with an upwardly bulging flange projecting laterally beyond the same, said flange having a depending rib spaced from the edges of the flange, said rib increasing in width downwardly, the rib of one tile being adapted for insertion within the groove of the adjacent tile, plastic material within the groove to anchor the rib therein, each tile being provided at its upper end with a transverse recess having its top open,- such top being covered by the lower end of the adjacent tile in the upper course, plastic material within the transverse recess to bind the tiles together, each tile being further provided centrally thereof upon its lower surface with a groove to receive said flange whereby the tiles in the different courses are arranged to break joint.

2. A roofing structure comprising, a plurality of tiles arranged in courses, each tile being provided at one edge and upon its upper surface with a longitudinal groove increasing in width downwardly and upon its opposite edge with a longitudinal flange projecting laterally beyond the tile, said flange being provided upon its lower side with a longitudinal rib spaced from the edges thereof and increasing in width downwardly, the rib of one tile being adapted for insertion within the groove of the other tile, plastic material within the groove to anchor the rib therein, each tile being provided near its upper end with a recess extending transversely thereof and having its top open and covered by the lower end of the tile in the upper course, said recess having its bottom provided with teeth, and plastic material within the recess to bind the ends of the tiles together.

3. A roofing structure comprising, a plurality of tiles arranged in courses, each tile being provided at one edge and upon its upper surface with a longitudinal groove increasing in width downwardly and upon its opposite edge with a longitudinal flange,

I said flange being provided upon its lower side with a longitudinal rib increasing in width downwardly for insertion within the groove of the adjacent tile, plastic material within the groove to anchor the rib therein, each tile having its lower end bent downwardly for forming a lateral extension, each tile being provided near its upper end with a transverse recess, having its bottom provided with teeth which face downwardly, and plastic material within the transverse recess to engage with said teeth and the lateral extension of the tile in the upper layer.

In testimony whereof I aflix my signature.

JOHN M. MARTIN.
