9 Claims.

This invention relates to metallic shingles and more particularly to an improvement in the inter-connecting features thereof, although certain features thereof may be employed with equal advantage for other purposes.

It contemplates more especially the provision of an improved metallic shingle which has a novel inter-connecting means to preclude seepage or leakage of moisture therethrough for lodgment on a roof, and the accomplishment of this effectual joinder with minimum requirements for material from which the shingle is constructed.

Numerous types of metallic shingles have heretofore been proposed, but these have not proven entirely satisfactory because there is an undue requirement for excess material in forming flanges and other connecting expedients which do not prove especially efficacious in precluding leakage or moisture seepage therebetween. The requirement for the minimum utilization of material to cover a given area with effectual means to effect the joinder,I of adjacent shingles, constitutes an important problem which has not thus far been successfully solved without the provision of a shingle which is comparably expensive and less effectual. This is accomplished by the teachings of the instant invention by the provision of effectual joining expedients on shingles for complemental attachment with adjacent shingles on the roof surface to preclude any possible drain or seepage thereon even though the joinder thereof does not constitute a hermetically sealed connection.

One object of the present invention is to simplify the construction and improve the facilities for joining adjacent metallic shingles.

Another object is to provide a metallic shingle having integral flanges constituting improved connecting means precluding moisture seepage to the building structure.

Still another object is to provide metallic shingles having inter-connecting flanges which serve as a drain for any moisture to the exterior surface of the lower adjacent shingle.

A further object is to provide novel flanged connectors on metallic shingles without unduly increasing vthe material requirements therefor.

A still further object is to provide a novelly formed flange constituting a connector with complemental expedients provided on adjacent shingles as well as a drain for moisture that may seep therebetween.

Still a further object is to provide a shingle having a novel connecting flange which precludes or at least reduces Amoisture Yseepage to a minimum and effects the drain thereof to the lower exterior surface of the lower adjacent shingle. Y

Other objects and advantages thereof will appear from the following description of an i1- lustrative embodiment of the present invention.

The structure selected for illustration comprises a substantially rectangular sheet Ill of material composed of aluminum or other materials which is of desired gauge or thickness to meet commercial requirements. The sheet I0 is provided with an elevated ridge I I impressed therein along the side edge I2 which terminates in a reversely bent flange I3 disposed beneath the sheet I in alignment with the upstanding ridge I thereof. As shown, the reversely bent flange I3 serves to define the edge I2 and an edge Ill spaced therefrom so as to afford the telescopic reception of a complemental flange extending therebetween from an adjacent shingle. The reversely bent flange I3 has a bracket l5 depending from the edge I4 thereof for exposed extension upon the surface of the sheet I0. It is to be noted that the bracket I5 is connected to the flange I3 by virtue of an upstanding arm I6 which is of triangular configuration to sustain the flange I3 in an inclined direction for reasons which will appear more fully hereinafter.

The fiange I3 is provided with apertures Il to enable the attachment of the shingle I l) to the roof surface by resort to any suitable fasteners such as nails. The flange I3 extends from the top edge of the sheet I Il for a substantial distance downwardly just short of a lower edged flange I8 provided therealong. The inclination of the roof attaching bracket I5 imparts an inclination to the reversely bent flange I3 of a degree depending largely upon the slope of the roof surface and this is utilized for the purpose of draining any moisture seepage that may find its way within the flange I3 between the edges I 2 and I4 thereof. 'Io this end, the lower surface I9 of the flange I3 is depressed to define a runway 20 which guides the moisture along the edge of the sheet I0 for deposit on the exterior surface of the lower adjacent shingle I0.

It is to be noted that the other edge 2| disposed parallel to the edge I2 is provided with an opposite reversely bent flange 22 disposed beneath the sheet Iii for telescopic engagement with the reversely bent flange I3. The flange 22 has a portion 23 thereof spaced from the sheet connecting portion 24 for a distance sufficient to receive the edge I2 together with its upraised portion I I. In fact, the flanged portion 23 is spaced for a somewhat lesser distance so as to yield slightly responsive to its application over the edge I2 of the adjacent shingle to effect a hermetic joinder therebetween. With this arrangement, moisture seepage will practically be avoided or at least reduced to a minimum by virtue of the .upraised edge portion I I which precludes moisture flow or entrance therearound. Should the lconnection be somewhat distorted or imperfect for any reason whatsoever, then the moisture will be collected in the runway 20 and thence drain to the exterior surface of the lower adjacent shingle as will presently appear.

As described supra, the lower edge of the shingle sheet I0 is provided with a flange I8 turned therebeneath for engagement with an oppositely hooked flange 25 constituting the top edge of the sheet I0. In consequence, the adjacent shingles I0 are provided with complemental flanges on all edges thereof for engagement and an edge shingle Ill is anchored or fastened to the roof surface by virtue of the bracket I5. Any suitableimpressions such as an upraised shoulder area 26 may be provided in the shingle `sheet `I I) so as to impart a suitable design ornamental appearance to the shingle surface when assembled in a manner more clearly described in Figure 9. The adjacent shingles II! are first anchored by means of a bracket I 5, and thence they are overlapped along their sides for engagement to preclude moisture seepage and afford the drain thereof should any occur by reason of imperfect joinder or variations occurring before, during or after the placement thereof. It will be observed that minimum material is utilized in the attaching lbrackets and flanges so that the cost thereof is reduced to a minimum and an effective joinder between adjacent shingles rendered possible without entailing any undue labor or time in the installation thereof.

In the modified embodiment disclosed in Figures 5 to 10 inclusive, the side -edged flanges I and 22' as well as the roof attaching bracket I5 are utilized as in the previously described structure. In this instance, however, the bottom flange I8 is provided with a reversely bent flange 21 which terminates in roof attaching brackets 28 for application to a roof surface along both the side and bottom edge for additonal insurance. The top edged flange 25 is telescopically disposed between the bottom edged vflange I8 and reversely bent extension 21 for engagement with the shoulder formed therein by virtue of a raised area 3D impressed therein. Otherwise the structures are substantially identical save for the additional bottom bracket 28 which is interrupted by a cut out portion 3| therebetween or along a vertical median line for rendering the top ange 2| of the lower adjacent shingle accessible for telescopic engagement and disengagement.

It is thus apparent that the shingles I and/or 10 I 0' are protected on all sides by flanges that are complemental to adjacent edges of successively laid shingles. The arrangement of parts above described affords the laying of shingles IG and/or ID from the top ridge of a roof to the eaves there- 15 of. In other words7 the shingles I Il and/or I3 are attached in horizontal alignment and interengagement along the ridge of the roof. These are individually laid for independent attachment by driving nails through the inclined flange I5 20 in shingle III and through both flanges I5 and 2d in shingle I0. Thereupon, the top flanges 25 and 25 of the next lower tier or row of shingles are inter-engaged with the lower edge flange I8 and I8' of the above tier just previously laid, 25 thereby affording top-down application of the shingles IU and/or I5. This coupled with complete inter-engagement along all edges with a special drain feature for all seepage, provides a novel, effective and comparably less expensive 30 shingle from a material and labor standpoint.

Various changes may be made in the embodiment of the invention herein specifically described without departing from or sacrificing any of the advantages of the invention as defined in 35 the appended claims.
