UNITED STATES GEORGE A. BELDING, OF PITTSBURGH, PENNSYLVAm I SHEET-METAL SHINGLE.

Application filed October 5, 1925. Serial No. 80,427.

This invention relates to shingles made of sheet metal, and has for an object to provide a shingle of this kind which can be .readily attached to the supporting sheathing or sub-structure of the roof without the use of separate auxiliary parts in the nature of special clips, and which will coact with adjacent shingles in a manner to assure the positive anchoring of both the upper and butt ends of the shingles upon the roof.

It is also an object of the invention to provide a shingle of the character referred to which while readily applied to the roof and interlocked with adjoining shingles with ease, will form highly effective joints for trapping and carrylng ofi" condensation and moisture from the underside of the shingles as well as preventing entrance of water by capillary attraction or otherwise from the outer side of the shingle.

It is a special object to provide a shingle of the so-called plain surface design made in comparatively large sheets while giving generally the same visual elfect as shingles of smaller size, and in which substantially the entire width of the underside of the shingle adjacent its upper edge will-firmly seat upon the sub-structure or supporting sheathing of the roof.

It is a further special object to provide a shingle having the features described which can steps and with the use of a minimum amount of material.

These and other objects of the invention will more fully appear when taken in conjunction with the following description and the appended claims.

In the accompanying drawings, Fig. 1 is a fragmentary view in perspective illustrating a section of a roof formed by, interlocking a pluralit of shingles constructed in accordance wit the invention; Fig. 2 a perspective view looking towards the upper surface of the shingle, and showing the offset sections comprising the body portion thereof, as well as the detailed structure at its upper and right hand side edges; Fig. 3 a view similar to Fig. 2 looking towards the under surface of the shingle, and showing the detailed structure of the L-flange forming the butt of the shingle as well asthe details ofthe joint at its left hand side edge; Fig. 4 a fragmentary view in vertical section showingthe detail structure at the upper and lower butt edges, respectively, of

e fabricated in a minimum number of two interlocking shingles, the parts being shown in the relative positions which they assume just prior to the engagement of an overlying shingle with the one immediately below it; Fig. 5 a view similar to Fig. 4 with the several parts shown in the relative positions which they assume after the shingles have been engaged; Fig. 6 a fragmentary vertical section taken through the roof illustrated in Fig. 1, and substantially in the line- 6-6 thereon showin the cooperation of the several rows of shingles upon the roof; Fig. 6 a fragmentary detailed sectional viewshowing the cooperation of the underturned butt L-flange with the raised ribs of the underlying shingle; Fig. 7 a view, taken substantially on the line 77 of Flg. 1, illustrating the cooperation between two adjacent rows of shingles upon the roof, the

plane of the section of the underlyin row passing through the depressed pane s adjacent their upper edges; Fig. 8 a fragmentary vertical transverse sectional view illustrating the detailed construction of the side joint, the parts being illustrated in the relative positions which they assume just prior to their engagement when assembled by sidewise movement of the shingles; and Fig. 9 a view similar to Fig. 8 showing the same parts in interlocked assembled relation.

Referring to the drawings, 1 designates generally the body portion of the several shingles which are off-set as indicated at 2 at a point intermediate their opposite side edges dividing the body of the shingle into two sections 3 and 4, respectively, the body portion of section 3 lying in one plane and that of section 4 lyin in a different plane slightly'ofi-set from t e plane of section 3.

Each shingle has an upturned openfolded flange 5 along one side, and at the opposite side with an underturned openfolded flange 6. These open flanges are adapted to be inter-engaged by sliding endwise, one within the other, as shown in Figs. 1, 7 and 9, or they may, be engaged sidewise by slightly springing one flange within the other, as indicated in Figs. 8 and 9. A corrugated bead 7 is preferably formed longitudinally in one of the flanges which not only spaces the flanges apart to form longitudinal ports or passages 8 along each edge of the bead, but forms a longitudinal port or passage 8' within the corrugation, which ports or passages serve to break the contact and trap any water which may enter the joint by capillary attraction and conduct the same downwardly to the lower end of the joint.

The body is slightly ofl-set as at 9 at a point spaced slightly from its upper edge, the metal being turned backwardly upon itself to form the superposed layers 10 and 10 lying in intimate abutting contact and the open-folded flange 11 spaced above the body, the free extremity of the flange having the lip 12 inclined away from the body in the direction of the butt edge of the shingle. To facilitate fastening the shingle to the sheathing 13, or equivalent sub-structure of the roof. the contacting layers 10, 10 at one side of the off-set 9 are provided with a plurality of spaced apertures 14 for the reception of anchoring means such as the nails 15.

The off-set 2 extends completely from the off-set 9 to the lower butt end of the shingle. and the section 3 is provided with an unbroken depressed panel 16 underlying the flange 11. The panel 16 is depressed to an extent corresponding to the extent of the off-set 2 so that the under surface of the panel lies in substantially the same plane as the under surface of the section 4:. This enables the underside of the shingle adjacent its upper edge to seat firmly upon the sheathing throughout substantially its entire extent from one side edge of the shingle to the other, all as will be clear from an ins ection of Fig. 7.

t the lower edge of the body is an under-turned L-flange having its stem 17 forming the butt of the shingle with its portion extending in the general direction of the body equipped at a. point intermediate its width with a downwardly extending corrugated depressed rib or head 18 and at its margin or free extremity with a down wardly inclined lip 19 projecting towards the upper edge of the shingle. The terminal of the lip 19 lies in substantially the same plane as the ridge of the rib or corrugation 18 so that upon interlocking the L-fl-ange by projecting it under the flange 11, in the manner shown in l-ig. 5, a sealing contact or joint will be produ ed by both the rib 18 and the lip 19 by their contact with the upper surface of the underlying shingle. The inclination of the lip 19 also cooperates with the lip 12 whereby to permit the ready interlocking of the interengaging flanges; The joints afforded by the contact of rib 18 and lip- 19 serve as a double guard against entry of water or moisture from the upper surface of the roof below the butts of the shingles, and it is particularly noted that the lip 19 can be easily formed in the same operative step during the fabrication of the shingle. Should moisture find its way past the rib and lip, further passage thereof will be prevented by the flange 11 and the sealed joint produced by the intimately abutting superposed layers 10 and 10.

From the above description it will be apparent that the stem portion 17 of the l.- flange of section 3 is of slightly greater depth than the corresponding portion of section 4, all as will be clear from an inspection of Figs. 1 and 7, the butt flange of section 3 overlapping the but-t flange of section 4 of an adjacent shingle in the region of the side joint therebetween, as illustrated in the said figures.

To enable adjacent shingles in the same row to be more easily interlocked and in a fashion to assure the stem portions of all the shingles forming a row to lie in the same plane, that is, terminate flush with each other, the stem of the butt flange is slightly depressed as at 20 on the side of the shingle carrying theside flange 5, and the flange 11 slightly raised and protruded as at 21 immediately over the side flange 5.

By depressing the panel 16 in the manner described, a short raised rib is left at 22. The portion of the L-flange underlying the body of the shingle is therefore appropriately indented at proper points as indicated at 23 and 23 so that these indents may straddle the ribs 22 upon interlocking the several shingles during the construct-ion of the roof. As illustrated, these indents are preferably positioned midway between the side edges and the ofl-set 2.

As illustrated in Fig. 1 of the drawings, the off-set 2 enables the use of comparatively large sized shingles while at the same time producing the visual eflect secured by shingles of half the size.

In use, the first row of shingles is applied adjacent the eaves of the roof, the side seams or joints of adjacent shingles of the same row being interlocked in the manner previously described. Each shingle is in turn securely anchored by driving nails 15 projecting through the apertures 14 into the sheathing or sub-structure 13. The overlapping shingles of the next higher row are then successively applied by projecting the portion of the l.-flange spaced from the body of the shingle within the space below the flange 11 of a shingle of the next lower row. aositioning the inter-engaging shingles of the successive rows in the manner clearly shown in Fig. 1.

Attention is called to the fact that the shingles may be easily and quickly anchored in place entirely without the use of special clips or similar separate auxiliary attaching means, that the shingle anchoring means provided at the upper edge of one row of shingle serves also as a means for positively locking the butt ends of shingles of the next row in place, and that the driving of the anchoring nails 15 home does not tend hand tends to to disrupt the sealed joint afl'orded by the which the inter-locking portions of the respective shingles are equipped with a plurality of sealing joints at their overlapping edges, but a construction which can be readily fabricated to its ultimate desired shape in a comparatively few steps and therefore at a correspondingly reduced cost. Due to the reduced cost of the shingles themselves, and the entire elimination of special attaching clips, together with the additional sav ing efiected both in material and the cost of the production of such clips, the practical importance of this invention will be at once appreciated by those familiar with the art.

As required by the patent statutes, the preferred embodiment of the invention has been illustrated and described. It is obvious, however, that many changes in details and in the arrangement of the several parts may be made without departing from the spirit of the invention. It is therefore not intended to limit the invention beyond that particularly set forth and defined by the appended claims.
