Application filed April 7, 1914. Serial No. 830,210.

Be it known that we, FREDERICK C. OVER- BURY and HOVVAKD CARLETON PLAT'rs, citi- Zens of the'United States, and residents,.re-

spectively, of New York, in the county of New York and State of New York, and of Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Tile Roofings, (Case F,) of which the following is a specification.

i This invention has for its object to produce a tile roofing, 0 a roof which when laid has the appearalnce of one made of clay or composition tles, which is durable, weatherproof and waterproof, cheap in con-' struction, easy to lay, land which is light in weight and easily packed for shipment. On. the accompanying drawings,-

Figure 1 shows a portion of a, roof equipped with the invention.

' Fig. 2 represents a section on the line 2-2 Fig. 3 representsa section on the line 3-3 ofFigfll. Fig; 4 shows one of the tiles.

For foriiiingthe tiles, we may use such material as has heretofore been employed for flatroofing, and therefore may. use many of the standard flexible prepared roofin materials now on the market. Such fiexi le material consists of a base or foundation-of wool felt or its equivalent saturated or impregnated with a waterproofing compound such as a hydrocarbon mixture, and coated with a facing or coating of a weatherproof substance such for instance as pitch or bitumenxhaving a relatively high melting point so that it will not be unduly softened by solar heat in warm climates. Such coating or'facing may beapplied while reduced to a soft and plastic stateby heat or when mixed with a volatile solvent. Such a-flexi blc roofing material cannot be bent at sharp angles, particularly in cold weather, after the coating has set or hardened, without danger of the coating cracking or breaking at the bend and thus rendering the material useless as a waterproof and weatherproof covering. rendered soft and plastic, either by heat or by the addition of a suitable solvent, the material may be bent at a sharp angle or folded upon itself so as to stretch and, elongate the The blanks or tiles thus formed When, however, the coating is coating at the bend or fold, and, if it be allowed to set or harden while so stretched or elongated, the folded or bentportion may be again, straightened or flattened without danger of cracking or breaking the coating.

Hence, in forming the tiles, c'ertain portions are bent or folded under when the coating is plastic. This will be understood without further explanation thereof.

Each tile is formed of a piece or blank served that the folded portion 5 is not equal in width to the entire blank, there being a reentr'ant angle formed at 7 by cutting away Substantially a. portion of the material. midway between its side edges, the blank is formed, while the coating is in a soft and plastic state, with an upstanding rib 8. This is formed by bending the blank first upon the longitudinal line 9 and then upon the longitudinal lines 10, 10. At the left-hand side of the blank there is a projecting flap or marginal portion 11, which, while the coating is plastic, is bent under the side edge so that when bent under the rib 8 is approximately midway between and parallel to the side edges of the blank. After the blank has been thus formed, it may be straightened out and packed with others for shipment.

are laid in transverse rows uponthe roof so as to form alternating curved and angular ribs. The tiles of each'horizontalrow overlap the tiles of one .or more preceding rows; and the tiles of each row overlap the adjacent tiles of the same row. In laying the tiles upon a roof, it is necessary to provide the supporting structure 12 with a plurality of parallel spaced bars 01 supports 13, which may be niade'of wood and which extend from the caves to the ridge so as to support the'curved ribs formed by thetiles. With the form of tile shown, the first tile of the row should be placed at the leftside edge of the roof, the flap 11 is unfolded, and the 11 per surface thereof is placed on the top 0 one of the ribs 13. Fasteners, such as nails or the like,

are then driven through the flap, afterwhich the main body of the tile is swung to the right until the valleys formed by the rib 8 rest upon the roof, with the right hand marginal edge of the tile resting upon the next adjacent bar or support 13. The next tile is then laid in the same manner, the nails or fastenings being driven through the flap 11 and through the side portion of the preceding blank or tile. The tiles are thus laid progressively from left to right until the first row is completed. In this way, the two adjacent side portions of each pair of blanks form a curved rib, and between the several curved ribs there are upstanding angular ribs. These ribs extend from the eavestoward the ridge. Then the second course is laid in the same manner, the tiles of the second row being placed so as tooverlap to a LOZlSldQltll'llB distance the tiles of the first row, this being continued until the roof is covered. Vl'hen the last row next to the ridge is laid, at which point the supports 13 are slabbed ofi' as indicated at 14, the overlapping side portions of the tiles are flattened so as to overlap to a greater distance the preceding tile, as clearly shown in Fig. i, so as to form a substantially fiat surface instead of a surface containing alternating curved and angular ribs. This flat surface emerges by gradations into the curved surface as shown in Fig. 1. The ridge may then be covered by overlapping flat blanks formed of the same or similar material as thatof which the tiles were formed.

From the foregoing description it will be seen that we have thus provided a roof which is ornamental in appearance and which looks he a roofing formed of clay or composition tile. This appearance is augiented by the fact that the tiles are provided with the folded-under portionsat their lower edges, which increase the thickness of the edges so as to form shadows and simulate the solidity and thickness of the clay tiles.

In order that the tiles may be made more tire-resistant and in order to increase the esthetic iilljl'till'nllc, we prcfcrablynnix with the coating material, before it is applied to the blanks or the sheets from which the tiles are formed, a suitable inert pigment, such for instance as ground hematite ore or other equivalent material.

Having" thus explained the nature of our said invention and described a way of making and using the same, without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what we claim is:

1. As a. new article of manufacture, a roofin tile consisting of a blank of noninetalhc flexible waterproof material having a weatherproof coating, said bl'ank being bent to provide a central upstanding rib, and upwardly and-outwardly curved side portions, and being-adapted to be elongated or contracted laterally to vary the angularity of the rib and the curvature of said side portions.

2. As a new article of manufacture, a

roofin tile consistingot' a blank of nonmetallic flexible water roof material having a weatherproof coating, said blank having a folded-under lower portion to appear thick in imitation of a clay tile, and a central upstanding riband convexlv curved side portions, one of said side portions having a fold to provide a flexibly connectedlateral flap to lie thereunder, said blank being adapted to be elongated or contracted laterally.

3. A roof comprising a supporting structure, a plurality of spaced bars'thereon, a plurality of tiles formed of flexible waterproof material coated with a weatherproof substance, said tiles being arranged in overlapping horizontal rows, each tile having at one side edge a lateral foIded-midcr flap in lapped engagement with the side marginal portion of the next adjacent tile, and fastenings passed through said flaps into said bars and covered by the body portions of the tiles, said tiles'being formed with angular ribs located intermediate of said supports, and with side portions arching said supports.

4. A roof comprising a supporting structure, aplurality otparallel spaced bars or supports thereon-and projecting fromthc surface thereof, and av plurality of flexible non-metallic fibrous weatherproof tiles havingoverlapping convexly curved side, portions restiin upon and fastened to said supports, and having located between said supports.

upstanding angular ribs In testimony whereof we have allixcd our signatures in presence of two witnesses.
