CHARLES SMALLWOOD, OF EASTMAN, GEORGIA.

METALLIC SHINGLE.

Application led December 14, 1921.

T 0 all whom it may concern.'

Be it known that I, CHARLES SMALLwooD, a citizen of the United States, residing at Eastman, in the county of Dodge and State of Georgia, have invented a new and useful Metallic Shingle, of which the following is a specification.

This invention relates to roofing and more particularly to a novel form of metallic rooting sheet employed for forming a roof. the sheet being especially designed so that adjacent edges thereof may be interlocked to secure the sheets together.

Another object of the invention is to provide a. lock joint of this construction to permit the sheet-s to be laid, or positioned to simulate a shingled roof.

vWith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com` bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a fragmental plan view of a roof formed of a number of sheets constructed in accordance with the present invention.

Figure 2 is a sectional view taken on line 2 2 of Figure 1.

Figure 8 is a sectional view taken on line 3 3 of Figure 1.

Figure l is a perspective view of the under side of a sheet.

Referring to the drawing in detail, the sheet forming the essence of this invention includes a body portion 5, which may be formed of suitable flexible sheet metal, one edge thereof being formed into a tubular portion 6 to provide a securing flange. The opposite edge of the body portion 5 is curved upwardly as at 7 where the same is curved downwardly as at 8 to provide a flange de- Serial No. 522,261.

signed to interlock with the flange G of the adjacent sheet.

As clearly shown by Figure l of the drawing, a portion of the upwardly and downwardly curved flange is cut away as at 9 to permit the adjacent upper sheet to be moved downwardly with respect to the sheet supported therebelow, so that the adjacent upper sheet will overlap the connection between adjacent upper and lower sheets.

The curved portion 8 terminates in a relatively straight flange 10 adapted to rest on the rooting proper,the flange being provided with suit-able openings to acommodate securing nails. Thus it will be seen that when it is desired to position sheets constructed in accordance vit-h the present invention, the tubular portion 6 of one sheet, and which extends above the roof surface, is positioned within the curved portion 8 of the adjacent sheet, and the sheet is then moved downwardly to cause the same to closely engage the roof.

lVhen the sheet is moved downwardly into engagment with the roof, it will be seen that the portion of the curved portion 8 adjacent to the curved portion 7 is moved into close engagment therewith, mal-:ing a fluidtight` connection at this point.

Having thus described the invention, what is claimed as new is In a shingle of the clase described, a body portion having its lateral edges rolled, one of the rolled edges overlying the body portion, the opposite rolled edge being rolled outwardly from the body portion of the shingle and inwardly upon itself within the said roll, the last mentioned rolled portion being cut away throughout a portion of its length, and the free edge of the last mentioned rolled portion extending in the plane of the body portion to provide an attaching flange.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature. CHARLES SMALLVVOOD.
