ROOF.

Application filed Novembcr 18,.1924. Serial No. 750,571.

The present invention relates to improvements in roofs for bulldlngs and other similar structures where a tire-proof and water proof covering are required. The roof is.

composed of tile of the ceramic or of concrete type used as shingles, and is designed to provide a wide and adequate weather lap to insure proper drainage and at the same time ati'ord economy in the use of the tile shingles.

The invention consists in, certain novel combinations and arrangen'ients of parts in volving the roof structure, the tiie shingles and a flexible sheathing beneath the shingles, as will be hereinafter more fully explained.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged in accor-dance with the best mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a view showing an angle of a gable roof structure with the tile shingles laid thereon, some of thelshingles and p01 tions of the sheathing being omitted for convenience of illustration.

Figure 2 is an enlarged detail sectional View of a portion of a roof structure.

Figure is a perspective view of one of the tile shingles.

in carrying out my invention I utilize the rafters of the roof structure indicated as 1 which are spaced apart in usual manner and provide parallel horizontally extending wood strips or battens 2 nailed or otherwise secured to the rafters and extending transversely thereof. The battens are spaced a considerable distance apart to accommodate the rows of tile shingles 3, the distance between the outer faces of adjoining battens being a little less than the length of the tile over all. The tile shingle is rectangular in shape and fiat, and at the underside of its upper edge is fashioned with a transversely extending flange t by means of which the tile is hung or supported from the roof batten 2.

Beneath the tile-shingles is arranged a sheathin which is waterproof and fireproof and preferably is made up in strips 5 of asbestos composition material. The sheathing strips extend parallel with the battens and are secured thereto as by nails, with the upper edge of each strip turned or bent down over the upper face of the batten as lndicated at 6 and secured to, the batten.

In laying the tile roof a strip of sheathing,

is first nailed to the two lowermost battens, the upper edge of the strip being bent or folded over the upper face of the upper batten. The exposed face of the sheathing,

strip and its folded edge are now given a coating of cementitious material such as asphaltum, root paint or other plastic material 1' to which the tile will adhere. The first course of tile-shingles is now laid on by hooking or hanging the tile over the upper of the two lowermost battens with the rib 4 supported on the sheathing bent over the upper edge of the batten. The tile is thus hung in position and supported on the batten and imbeds itself in the plastic material or coating on the sheathing to form a close and water tight joint. The tile-shingles are thus laid to complete the first or "lower course.

For the next and succeeding courses of tiles the sheathing is attached at one edge and bent or folded over a. batten with the lower edge of the sheathing overlapping a portion of the upper or head end of the t1leshingle. That portion of the underface of the sheathing which comes in contact with the battens, or the underside of the lower edge of the sheathing strip that overlaps the head of'the tile, is also coated with plastic cementitious material so that the sheathing will adhere to the batten and the lower edge of the sheathing will adhere to the row of shingles which it overlaps.

The second course of tile-shingles is now laid on the coated sheathing, the tiles of the second course being staggered with relation to the, first course and so on. i

. The weight of the tile-shingles is thus borne by the battens, one of which supports a course of tile, and the tile-shingles are per.-

hardened plastic material mashed between the tile-shingles as the course is laid, the water is prevented from reaching even the sheathing below the tile-shingles.

The tile-shingles of course are impervious to moisture and as their expansion and contraction under diii'ering weather conditions is slight they may be laid up closely together without danger of warping.

The lower ends of the tile-shingles overlap the head ends of the next course below suiiiciently to make a weather-tight and waterproof joint, and afford adequate bearing for the lower ends of the tiles in the course. And it will be apparent that this arrangementof tile courses permits the use of a minimum number of tile-shingles to cover the entire area of the roof structure, thus insuring an economy in the consumption of the tile-shingles. The sheathing and cementitious material perform the function of cushions for the tile and thus eliminate danger of breaking and add durability to the roof structure.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is In a roof structure the combination with supporting rafters carrying transversely arranged spaced horizontal battens, of applicable sheathing strips applied over and extending between adjoining battens with their upper edge? folt ed over and secured by cementitious material to the upper battens, a layer of cementitious material substantially applied over said sheathing strips, tileshingles applied in staggered courses over said sheathing strips by embedding in the cementitious material, ribbed heads formed on said tiles for hooked engagement over the upper faces of the upper battens beneath the lower free et ges of said sheathing strips, said lower tree edges of the sheathing strips being coated on their under faces with a cementitious material for binding engagement with portions of the tiles disposed therebeneath.

in testimony whereof I aiiix my signature.
