METALLIC SHINGLE Original Filed Feb. 29, 1932 I/l/ Ill/I72 Fabio/w: LEN/YELl/L 4 E Inventor y Mm Attorney .i atenteol A r. l7, 1934 UNITED STATES PATENT OFFICE Application February 29, 1932, Serial No. 595,909 Renewed December 19, 1933 3 Claims.
My present invention relates to improvements in metallic shingles or roofing sheets, stamped or rolled, preferably from zinc, and laid on the sheathing boards of a roof, with approximately one half their length to the weather, and the other half of lap, to insure a well sealed and weather tight roof covering. In carrying out my invention the exposed or weather-end of the shingle or sheet is fashioned approximately twice the thickness, and of greater strength, than the lap end of the shingle or sheet, and the exposed end or portion of the shingle or sheet is made more durable by dipping or otherwise coating the shingle with lead to insure not only a weatherproof shingle, but also to protect it against corrosion by acids from fumes, smoke, and other deleterious atmospheric conditions.
Rib seams are provided for the overlapping margins of the shingles or sheets to insure accuracy and convenience in laying the shingles, and to assure weathertight joints that are closed or sealed against driving rain or snow, and Wind, and air spaces or cells are provided between the lapped portions of the shingles for venting purposes.
In their preferred size the roofing sheets are of greater dimensions than the standard shingle, and the sheets, which may be nailed through their thin portions or lapped ends, may be laid with facility, and the roof covered in comparatively short time with slight expenditure of time and labor.
The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed. In the accompanying drawing I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have thus far devised for the practical application of the principles of my invention.
Figure l is a perspective View of one of the metallic shingles or roofing sheets embodying my invention.
Figure 2 is a sectional View through a portion of a shingled roof, according to my invention.
Figure 3 is an enlarged and exaggerated sectional view through a roofing sheet showing the two thicknesses of the sheet and the lead coating for the two sides of the weather or exposed end of the sheet.
Figure 4 is an enlarged, horizontal sectional View showing the overlapping lateral edges or margins of two sheets.
In Figure 3 a conventionalized sectional view of a roofing sheet or shingle is shown, with the lap-end 1 of approximately one half the thickness of the exposed or weather end 2, and the latter end is dipped or otherwise coated as at 2. The roofing sheet is stamped or rolled from zinc blanks and the blanks are cut into the desired shapes of suitable sizes, preferably larger than the standard shingle, and the non-corrosive coating for the zinc sheet may be lead, or other suitable material.
The roofing sheets may be laid on a fiat roof and welded or soldered, or as in Figure 2 the slanting roof comprising the rafters R and sheathing boards S may be covered and the roofing sheets are secured by nails or otherwise.
As best seen in Figure 1 the sheets are fashioned with lateral exterior ribs 3 and 4 at 0pposite edges, which form interior grooves, and between these lateral ribs are arranged parallel, intermediate ribs 5. The ribs are spaced equidistant, and extend the full length of the sheet, and as indicated the ribs taper, with their smaller ends at the free edge of the lap end and their larger ends at the free ends of the exposed portion of the sheet, and at both sides of the intermediate ribs, as well as at the inner sides of the lateral ribs, exterior grooves 6 are fashioned in the sheets, and these grooves provide for interior ribs 7. Thus the sheets, not only overlap at the opposite ends, but they overlap at their lateral edges, when laid on the roof structure, and as seen in Figure 4, the lateral edge or tapering rib 3 fits over the outer one of the intermediate ribs, and the lateral edge or rib 4 is covered by another of the outer ribs of the intermediate series 5. In other words the sheets or shingles overlap approximately one half of their length, and at their lateral edges the sheets overlap the distance between a lateral rib and the adjoining intermediate rib.
The lateral ribs and their complementary intermediate ribs form the spaced rib-seams in the roof, and the double sealing of the lateral edges of the sheets as in Figure 4 insures a weather tight joint that is impervious to wind, water, or snow. The exterior grooves 6 provide longitudinal drains for carrying off rain water and, as best seen in Figure 1 these grooves start at the approximate transverse center line of the sheets and extend to the lower extremity of the exposed end of the sheet. The grooves 6, and the complementary ribs 7 start at zero and flare or taper outwardly toward the free edge of exposed edge of the sheet, and these inverted ribs 7 thus provide a covering for the lateral ribs 3 and 4 of complementary sheets, as well as form drains for the exterior faces of the sheets.
As best seen in Figure 1 each sheet is provided with a rounded edge or half-rib 8, which extends across the full width of the sheet, but merges with the intercepting lateral and intermediate grooves. These rounded edges or half-ribs fit over complementary transverse ribs 9, located at the approximate centers of the sheets, and these intermediate, transverse, ribs also extend the full width of the sheets and intercept the longitudinal ribs 3, 4, and 5 of the sheets. The function of the complementary half ribs 8 and ribs 9 is to seal the horizontally extending joints, and form rib-seams in the roof for the exclusion of wind, rain, or snow, as indicated in Figure 2.
Between the overlapping portions of the sheets, as seen in Figure 2, air spaces or cells 10 are formed for venting purposes and to prevent accumulation of dampness within the roof covering. The sheets, which are fashioned of comparatively light-weight material are strengthened by the use of the longitudinal and cross ribs, and as a consequence the strength and durability of a heavy roof are provided with a comparatively light load on the roof structure, and a well sealed and weather-tight roof covering is insured.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:-
of the sheet.
3. A rectangular roofing sheet of metal having a lap end and an exposed end of varying thickness, lateral grooved beads and intermediate, spaced grooved-beads, an intermediate transverse intercepting bead forming a seam groove, a seam groove at the edge of the exposed end, said lateral and spaced intermediate beads increasing in cross area from the upper edge of the lap end to the lower edge of the exposed end of the sheet, and inverted beads forming exterior grooves of increasing cross area from the transverse intercepting head to the lower edge of the exposed end of the sheet.
