To all whom t may concern:

Be it known that we, FREDERICK C. @ven- Bnnr and HOWARD CARLETON lPLrfrs, citizensof the United States, and residents, respectively, of 4New 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 usefulv llmprovementsin- Flexible Convex Tile Roofing, (Case F,`) of whlch the :following is a specification. y

This invention has for its object. to pro vide a roofcoveringwhich can be lald to produce the ornamental ed'ect of tiles.

Roofing tiles have heretofore been c ast or molded of clay or equivalent-composition 1n rigid form and produce'an appearance of solidity and a highly ornamental edect when in keeping with the architectural design of the building. Such tiles, however,

are relatively expensive to the user yboth on account ofthe cost of production, the breakage, and the weight which adds to the cost `and weatherproof and substantiall of transportation.

Our purpose is to produce a dexlble nonmetallic tile, which can be produced in large quantities at low cost, whlch is waterplf'oof proof, which can be produced in different colors, and which is light in weightl and easilyv laid. l J l 0n the drawing- Figure 1 showsa portion of a roof provided with tiles embodying our invention. Fig. 2 shows another form of the tileembodying our invention. Fig. shows hovvl the tiles may be bent. at the eaves. Fig. 4 represents a cross sectlon through a tile and illustrates a crimped or ribbed blank for supporting the convex portion of the tile. Fig.l 5 represents a perspective view of the ribbed blank. Fig. 6 shows the tile itself as provided with a portion which supports the convex Vportion thereof. Fi ofgthe roof. Fig. 8 shows a magnied section through a bent portionof one of the preferably saturated or impregnated with va 7 represents a cross section at the ridge l waterproof compound, such asa hydrocarbon having a relatively low melting point. One or both sides of the blank is coated with a' relatively thick coating or layer of weatherproof material, such as a pitch or bitumen having a relatively high melting point so that it will not be affected by solar heat. This outer coating is preferably applied after 'being heated to a soft and plastic state, but it may vbeV mixed with a volatile solvent and applied cold. Any suitable composition, which will serve the purpose, may be employed for the outer facing `or coating. Preferably, the coating substance or compound has thoroughly mixed with it a suitable `inert pigment, such, for example, as ground hematite ore, to color it and to add th(` fire-resistant qualities of the tile.

When a blank or weatherproof coverin is made as we have described, it is iexible and pliable, but, after thecoating has set or hardened, it cannot be bent atl a sharp angle without'danger of cracking and break# ing the outer coating, a fact which is recognized by those familiar with this art. .But

we have found that, when the coating is coating or facing, and that, if the stretched or elongated coating be allowed to set or harden, thereis formed what may be termed a hinge, at the bend; and that, when the material is subsequently bent back and forth about the line of the hinge, the coatingwill not break or crack.

- Patented tiet. 2e, TFT."

We have illustrated conventionally in l 8, a portion of a sheet, somewhat magnilie in which the impregnated body a has'the two coatings or facings b, c of weatherproof compound. When the material is bent, the outer coating is stretched or elongated at b and is compacted and corrugated at c. When the coatings have been permitted to set or harden, the sheet may be straightened without cracking the coatin at b.

' Preferably the felt foun ation is'either two ply or three ply, so called but, in

either event, it is thin as compared with a .clay tile, and when laid would not form marked division lines 4between the tiles of a vertical row, z'. e., a rowoftiles extending 4froth the eaves toward the ridge. To over come this defect, we have found that, by bendingv under the lower portion of the tile toform a fold inthe material, an edge of sullicient thickness is produced to form a shadow, and tol give the tile an appearance of considerable thickness and solidity.

On the drawings, the supporting wooden v `structure of the roof is indicated at 10, and

upon it are placed the tiles in what may be termed horizontal and vertical rows. Each tile consists of `a blank of the material described, said blank being substantially rectangularin shape. While the coating is soft .and plastic Y lits;,lower edge portion is folded under the "body portion thereof, and then, by any suitable means, the tile is bent into shape and the coating permitted to set. As shown in Fig. 1, the blank at one side portion is bent or folded at 12 and 13 to form we provide means for sustaining and supporting the curved body portion. The supporting means may consist of wooden strips placed upon the roof structure or supports `within or under the an y side portion of the other, so that between the formed of flexible material such as that of which the tiles are made, or supports form# ing integral portions of the tiles themselves. Wooden bars or strips are indicated at 17 in Figsi/lV and 2. In Figs. 4 and 5, the supports are made of sheets or strips which are bent or folded on longitudinal lines to form.

flat'side edges which may be secured to the roof structure and one or more upstanding angularribs 19 with which the concave surfaces of the wide curved ribs 16 engage.

But, as shown in Fig. 6, the rib supports maybe formed integrally with the tile, in

which case the tile is bent under Aupon itself at 20, and the bent -under portion is so formedy as to provide the upstanding angular ribs 21, 21 under the curved rib 16 and with the portions conforming to and fitting under the angular ribs of the body portion of the tile.

In laying the tiles, the supports for the curved ribs (if separate from the tiles) are first secured to the roof structure in parallelism at the proper distance from each other.

1 Then a horizontal row of tiles is placed on the roof with the side portion of one overlapping the side portion of the one onthe right thereof. They may be laterally overlapped, as shown in Fig. 1, so that the angular rib on the right side option of one lies ar rib on the left wide curved ribs there is a single angular rib. Or, if desired, they may be laid as shown in Fig. 2, in which case the marginal edge portion 22 extends into the concavity formed lby the angular rib of the next adjacent tile,.so that two angular ribs are providedbetween the adjacent curved ribs. As the tiles are laid, nails or other fastenings are driven through the upper portions of the tiles at any convenientpoints, as indicated y at 23, where they will becovered by the tiles of the next higher horizontal row. Then the next horizontal row of tiles is laid in the same manner, but so as to overlap the tiles already laid and so as to cover the nails orother fastenings by which the latter were secured in place. The tiles of each succeeding row are laid so that the angular and curved ribs register with those of the preceding row. When the ridge is reached, the ridge is covered by overlapping tiles 24, the side portions of which are folded back and forth as shown in Fig. 7 to form thick edges, and secured by fastenings 25.

At the eaves, the lower portions of the tiles of the rst row are slit along the lines of the bends 13 and 14 to form two flaps 26, 27 which are bent at 28, 29 so as to overlap, as shown in Fig. 3, to close the recess formed by the ribs,` and their corners are secured to `the end of the roof structure 10 by fastenings 30. They are also slit and bent to form overlapping flaps 31, 32 and 33 to close the recess formed by the curved ribs, and said flaps are fastened to the roof structure. The flaps may be riveted together at 34, or nailed to the support 17, and the flaps 31, 32 may be nailed to the end ofthe roof structure as shown at 35, 36.

A roof provided with tiles as described is ornate, and presents an appearance of thickness and solidity. The tiles are easil laid without requiring great skill and without the expenditure of much time, as will 'be readily appreciated. The degree of curvature of the curved ribs may be varied by placing the supports at different distances from each other, and thus having the angular ribs closer together or farther apart.

For shipment,the tiles may be flattened and packed together, without danger of cracking or breaking the coatin thereon. The folded-under portions of t e tiles so strengthened and stiiened Vthem that they maintain the ribs in their curved contours, after they are once securedin place.

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

1. A laterally extensible roofing tile formed of non-metallic flexible 'material coated with a waterproof compound, said tile having a 'folded-under lower edge portion, side portions bent to form upstanding `gibs, and an intermediate upstanding con-y 2. A roof comprising a plurality of parallel spaced supports, an'd a plurality of non-metallic flexible tiles each having a coatin@ of waterproofing compound, said tiles belng laid in horizontal rows with one row overlapping the preceding row, and with the tiles of each row laterally lapping each other, said tiles having convex curved ribs bridging said supports.

3. A roof comprising a plurality of nonmetallic flexible fibrous tiles each having a coating `of waterproofing compound, said tiles being laid in horizontal rows with one row overlapping the preceding row, each tile having lapped side portions bent to form flexibly connected upstanding ribs, and havf ing an intermediate conveXly curved upstanding rib, the several ribs of the tiles in one row overlapping and forming continuations of the ribs of the tiles of the preceding row or rows.

4. A roof comprising a plurality of non- Inetallic flexible tiles each having a coating of waterproong compoundfsaid tiles being laid in horizontal rows with one row overlapping the preceding row, each tile having lapped side portions bent to form upstanding ribs, and having an intermediate conveXly curved upstanding rib, the several ribs of the tiles in one row overlapping and forming continuations of the ribs of the tiles of the preceding row or rows, and parallel supports beneath the curved ribs and concealed thereby.
