SELF-VENTILATING SHINGLE.

Specification of Letters Patent. l Patented B131. 19, 1918.

Application led August 5, 1916. Serial No. 113,353.

To all whom it may concern:

Be it known that we, EDWARD ARTHUR SEWARD, a subject of the King of England, and HOWARD W'. KEY, a citizen of the United States, residing :tt-Columbus, lin the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in SelfsVentilating Shingles; and we do hereby declare the following to be a full, clear, and exact description of the invention` such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in metallic roofing, andparticularly to sheet iron roofing whether in shingle size or larger sections. c

The primary object of this invention is to apply to a roofing of this nature a ventilating means simple and effective in character.

A further object is to obtain a Ventilating sheet iron roofing adapted for covering hips and cones, and, in fact, every part of the roof except the valleys.

With these and further objects in view, as will in part hereinafter be specified and in part become apparent, the invention cpmprises certain novel constructions, comb1nations, and arrangements of parts as subsequently specified and claimed.

In the accompanying drawing,-

Figure l is a perspective view of a number of assembled sheets of metal roofing embodying the invention.

Fig. 2 is a plan view of a single sheet with the hood cut awav and seen in hori zontal section.

Fig. 3 is a perspective view thereof.

Referring to the drawing by, numerals, 1 indicates a sheet or shingle having a centrally located longitudinally extending folded portion forming a hood 2. Hood 2 is formed of an arch connected by offset portions 2 of flat material with the upwardly turned portions 2" of the sheet. Portions 2 extend inwardly from the arch cover` of the hood 2 and overhang longitudinal inner portions of sheet 1. Portions 2 thus overhang main portions of the sheet and are spaced above the same. The space between the main portions of sheet 1 and the portions 2 are connected with the interior of the hood by a row of apertures 2B formed in each oifset portion. 2. The curved portions 2 provide a passageway between themselves for through apertures 2a.

The sheet l is formed with a groove aty one edge and a corresponding bead at the other for interlocking with other like sheets after the manner indicated in Fig.v l. The V interlocking is effected preferably by a longit-udinal sliding or telescoping action in as,- sembling the sheets.. In order to facilitate this telescoping action, one end, generally known as the upper end ofthe shingle or sheet, is formed slightly narrower than the other or lower end.

s It is to be noted that the apertures 2a are so placed beneath the hood asto eliminate liability of the entry of rain, but at the Same time they perform the desired function of permitting of thorough ventilation. In ordinary and in extreme hot weather', the heat will penetrate metallic roofing of any nature, and in order to avoid the discomforts rof retaining andv accumulating such heat,

this invention has been so constructed as to allow any collection of heated air to pass from under the shingle and up through the hood and out through the apertures It will be clear from the drawing that the roofing plate l with its hood 2 and connecting parts is a single sheet stamped, bent or otherwise crimped into the shape shown and described, and there is no seam of any kind along any line or at any point of the jointure between the hood and the body of the sheet` It should be also observed that the apertures 2a are nearer the outer edge of the respective offset portions 2 than the inner edge thereof so as to facilitate draining of any slight particles of moisture which may be blown up through the apertures and into the hood.

Vhat is claimed is:

l. A shingle for roofs comprising a substantially fiat sheet having interlocking lateral edges adapted to interfit `with correspondingly formed adjacent shingles, said fiat sheet having between its lateral edgesa longitudinally extendingI fold forming a hood overhanging the lateral portions of the sheet and an air passage between the inner spaced apart ends of the sheet portions beneath the hood, said sheet also having lines of perforations in the underside of the hood above said opposite lateral portions of the apertures therethrough communicating thel 4interi-'or tof .thehood Wirth the surrounding atmosphere, kfand curved portions leading @from the inner edges of'. the offset portions down to the flat portions ofthe sheet.

3. A'roof covering lcomprisinga sheet of substantially flat material shaped intermedie atei itsfedges. into =anY upstanding hood hava substantially arched 'eoveryoffset fi-n- -W-ardly.directed portionsexitending from the 1 -edges of thefarched portiomandscurved portionslfleading 'ifromthe inner edges fof the offset; portions fd'own tof t'heilat portions of itherlsheet, ythe offsetl portionsafbeing 'formed wvifth apertures between the planes of the edges of the hood.

el. A roof covering comprising a sheet of material formed `at its 'edges With interlocking elements adapted to interlock with like sheets and formed intermediate its edges with a downwardly opening hollon7 hood ups'tanding from the surface of the sheet and having portions overhanging the upstand ing portions of the hood, the upstanding portions of the: hood beingecurved, and the Verhangfing portions f being formed with leper-'tures for 'a lord-'in'g communication a between ythe':interior ofthe hood'and jthe eX- terior atmosphere.
