F1ING.

Application filed August 30, 1926. SeriaI No. 132,477.

This invention relates to weather strips for roofing.

In covering roofs with shingles of tile, slate, or other material, the practice has been to render the roof water-tight by laying the shingles in courses in such a manner that at all parts of the roof area there were not less than two layers of shingles between the exposed upper surface of the shingle asseml0 bly and the roof sheathing in order that all exposed vertical joints could be underlaid with respect to the upper 'or unexposed end of another course of shingles, for the purpose, mainly, of providing water conducting gutters at the interstices between the adjacent shingles of each course.

The roofing system above outlined is suitable where relatively thin tapering shingles are employed; but with thicker shingles having little or no taperas flat tile, for example-such a method is objectionable on account of the quantity of material required to lay the roof by this method.

The object of my invention, generally stated, is to provide a light-weight, inexpensive, easily applied and efiicient device which may be used in lieu of a large proportion of shingles which have hitherto been requisite in the laying of a water-tight roof.

More specific objects and advantages of the invention will appear in the following description.

The invention consists in the noval construction, arrangement and combination of ."5 iarts hereinafter described and claimed.

In the accompanying drawing,-

Figure 1 is a top face view of a portion of a tile roof embodying the present invention; Fig. 2 is a longitudinal vertical sec 1 tion taken on line 2-2 of Fig. 1; Fig. 3 is a detail sectional view on line 33 of Fig. 2,. the upper course of tile being omitted from Fig. 3; and Fig. 4 is a perspective view of the weather strip which is utilized in the preceding views.

Fig. 5 is a view similar to Fig. 2 illustrating a modified construction of roof; and Fig. 6 is a perspective view of the weather strip used in the roof construction illustrated in 'Fi 5.

eferring first to Figs. 1 to 4, inclusive, 10 represents roof boards which are secured in a well-known manner to the framework (not shown) of a roof structure; and 11 represents roof paper, or an equivalent, which is customarily employed u on the u er surface of a roof board ass mbly. PP

12, 12 and 12 represent shingles or tile, as they will hereinafter be designated, of three roofcourses. The tile shown in Figs. 1, 2 and 3, being of the type which is conventionally known as flat tile, each being of a substantially rectangular shape and of substantially the same thickness throughout.

The tile of the respective courses are laid in side by side relation with relatively narrow spaces 13 therebetween. The tile of each succeeding course, after the first course, are laid to slightly overlap the tiles of the course next before laid. In accordance with the present invention such overlapping portions are insufficient to bridge the distance between the lower edge, as 14, of a superposed course and the upper edge, as 15, of the next lower course; in other words, there is space between the lower and upper edges 14 and 15, respectively, of the alternate courses of tile.

The tile in the successive courses, however, are laid in a manner to break joints with each other-that is to say, to have the interstices 13 of each course outside of the planes of tile interstices of the courses next above and below the respective course.

'F or each of the interstices between adjacent tile of every course thereof, I provide a weather strip (see Fig. 4) comprising a strip of sheet metal, preferably copper, whichis pressed or otherwise formed with a cross section of substantially the shape of an inverted capital letter central ridge 17 with laterally protiuding flanges 16.

The flanges 16 are grooved or corrugated to provide in the upper surface of each flange one or more gutters, two being shown, which are indicated by 18 and 19, respectively.

The ridge 17 and the gutters 18 and 19 extend longitudinally of a weather strip for the entire length thereof or nearly so.

For use with flat tile, as shown in Figs. 1 to 3, a weather strip is provided at an end of each with upwardly directed lugs 20, constituting hook elements to engage against the upper ends of the tile which are seated upon the respective flanges.

Thus arranged, the ridge 17 of a weather strip extends upwardly into the interstice between the proximate side edges of the tile T to provide a and serves toprevent lateral displacement of the weather strip wi h respectto the tile which are thereby supported.

In practice, the tile areulaid in approximately horizontal courses, beginning with the lower course of tile 12. The roofer disposes the tile and weather strips alternately, nailing each tile in place and hooking each weather strip over the upper edge of the tile.

- The weather strips and tiles 12 of the next course are next placed in overlapping relation with the tile of the first laid course and the tile 12 secured by nails, the weather strips and tiles, 12 are then laid, and so on with each succeeding course until the weather strips and the tile for the entire roof area are laid. The nails for securing the tile are represented by 21 in, Fig. 1.

. In Fig. 5 I show a modified form of tile, denoted by 120, 120 and 120 for therespective courses of a roof. The individual tile being characterized by each having along its upper edge a downwardly extending flange 23 which is engageable with one of a series of cleat elements 22v provided therefor on the roof structure.v

For the flange type of tile shown in Fig. 5, the weather strips are similar to those explained above for the flangeless type of tile except that the lugs or flange extensions, denoted by 20 are turned downwardly into engageable relation with the root cleats 22, see Fig. 5, which retain the tile in place.

It is to be noted that the tile are secured to a supporting roof frame structure; as, for example, by means of nails 21 (Fig. 1) or by means of flanges 23 (Fig. formed upon the tile, engaging roof cleats 22.

The weather strips, however, are connected either to the tile directly or to the cleat to which a tile is coupled, the purpose being to" simply retain the weather strips in Opera 'tive relations with the tiles pertaining thereto. It is also to be noted that my improved tween spaced apart alternate courses of tile.

The grooved flange elements 16 of my improved weather strip ext-end below the associated tile of the respective courses to afford gutters for conveying away any water enter ing the intersticesbetween the tile. The

ridge 170i a weather strip is of less height than the thickness of a tile and by locating the flanges entirely below the tile of the respective courses, the weather strips are hidden from view and do not render a tile roof unsightly.

The term tile as hereinbefore employed is not intended to limit my invention for use with a clay product exclusively, as it may be advantageously employed with slate and other kinds of shingles.

What I claim, is,

1. A weather strip for a shingle root comprising a metal strip consisting of a transversely folded sheet of metal having a longitudinally extending laterally folded ridge and two laterally disposed flanges longitudinally grooved, and having at one end, lugs projecting at right angles to the planes of the flanges, adapted to engage the upper edges of the shingles.

2. A weather strip for a shingle roof embodying a struck up metal st "ip having a longitudinally folded ridge, adapted to extend upwardly between the adjacent edges of two shingles on tiles and havinglaterally projecting flanges, longitudinally corrugated to form gutters, and formed with end flanges bent perpendicularly to the plane of the corrugated flanges and adapted to abut against the ends of the shingles at the side of the central ridge of the strip.
