Application February 18, 1938, Serial No. 191,232 o claims; (ci. 10s-s) This invention relates to materials used in building construction and more particularly to ements which may take the general form of a shingle, a clapboard or the like for roofing or 5. siding purposes. 'The object is to provide an im proved construction whereby a light, durable and highly weather-resistant sheathing may be pro'- vided for a roof or wall. For convenience in the following description I will use the specic word "shingle".

My invention will be well understood by reference to the following description taken in connection with the accompanying drawing, wherein:

l rig. 1 is a pian View illustrating a stage in the construction ofthe improved shingle;

Fig. 2 is an end view thereof;

Figs. 3 and 4 are rear and iront views respec tively of the completed shingle;

Figs. 5 and 6 are sections respectively on the lines d-l and 8 6 of Fig. 3 but on a larger scale; and

Fig. 7 is a simplified view chiedy in vertical section illustrating the method of applying the shingle.

I will rst describe briey the general construction of the shingle shown. It comprises a core with a bulk-giving body C (Figs. 5 and 6) for which I prefer to use double-faced corrugated cardboard. This is enclosed within a sealed covering of water-resisting material, preferably a sheet of asphalt-saturated craped paper B, which may be of the type described in my Patent No. 1,984,910, Dec. 18, 1934. At least that portion V of the shingle which is exposed 4to the weather is covered with a weather-resisting material, herein light sheet copper as denoted by the symbol Cu used as a reference letter. This may be of a gauge weighing a few ounces per square foot and may be conveniently characterized as foil. Referring to Figs. 3 and 4 of the drawing, the .copper covers the entire outer face of the butt portion of the shingle and has its margins folded! over on the rear, as seen in Fig. 3. In the present instance the upper end of the shingle and the rear face are not covered, although they might be if desired.

A suitable taper for the shingle may be provided by a diiferential crushing of the corrugations, as illustrated in Fig. 6. It may be remarked y here that for simplicity the corrugated central sheet of the4 board has in Fig. 6 beenshown by a single line while Fig. 7 has been further simplided and it has not been attempted to indicate therein by section lining all the various thicknesses of material utilized in the construction more fully illustrated by the other figures.

The core C may consist of a plurality of thicknesses of corrugated board to give proper bulk i0 and in the illustrative example of the invention I have shown such multiple thicknesses as anorded by suitable folding of. a single sheet; Referring to Fig. 1, the core C there comprises acentral body portion I0 and lateral portions I2 of-lesser height defining" a downward extension il. As 5 will appear, the length of the wings I2plus a half the vertical length of the extension it corresponds substantially to the length of the nished shingle when it is in place. The wings i2 are half the width of the central body It and 10 are adapted to be folded over thereon, and fold lines i6 are here formed by crushing down the corrugated board toward one side thereof, ythe further side viewing Fig. 1, so that the material in these zones is disposed substantially in the 15 plane of the outer covering sheet forming a sheet-like connection between the central body and the wings of a width substantially equal to the combined thicknesses of the connected parts. A transverse fold-line I8 is similarly formed mid- 20 way of the extension il so that if the distal end of the ,latter is foldedmup it will reach substantially to the lower edges of the wings i2.

The blank for the core, as shown in Fig. 1, may be disposed upon the sheet 8 of asphalt-saturated paper, of slightly greater height and of sufficient 25 width to provide the overlap margin 20. The face of the core, as seen in Fig. 1, may be coated with asphalt and the two wings l2 then folded upwardly, viewing the figure, over against the face qf the main body lo, the outer edges of the 3- wings abutting centrally of the central portion ill. As seen in Fig. 3, the margin 20 will form an overlap sealing the covering longitudinally of the shingle and the 'papert is pressed `down to the '35 contour of the enclosed core and sealed as is facilitated by the somewhat expansible character given it by craping. 'I'he upper end of the shingle may then be rolled or pressed to crush the corrugations of the core differentially and provide the taper illustrated in Fig. 6. I'he lower or butt portion of the shingle may then be covered with dthe foil Cu, the folded over margins or anges of the latter being pressed into close adherence to the body, as is permitted by the light and flexible character of the metal. The sheeting is securely held by the asphalt with which the paper 8 is saturated. Forl clearness I have here, described the folding zone i8 as formed initially in' the core blank. If desired, it might be formed 50 after the core is covered, the elasticity of the craped paper covering 8 and the malleability of the copper permitting this Vtobe done.

f As so far described, the shingle has the form shown in Fig. 6 with a tapered upper portion 55 comprising two thicknesses of corrugated board, the outer of which extends therefrom dening an inner shoulder 22 (Fig. 6), and this`extending portion has the forwardly depressed folding zone Il substantially midway of its length. The lower 15 to denne fold lines, the board being folded along portion of the extension Il maybe folded rearwardly relative to the body of the shingle, bringing its distal edge opposite the shoulder 22 and providing a uniform tapered structure with'the weather-resistant coating such as the copper foil Cu extending unbroken around the thick butt thus provided. Thus in applying the shingles to a building they may be placed in position with the tapered end downwardly and the left hand side, viewing Fig. 6, outwardly and nailed through the distal portion of the extension I4 outwardly of the crease line I8. The main body of the shingle may then be folded up about this line, covering over the heads of the nails, as illustrated in the upper portion of Fig. 7, and the sheathing completed in this manner.

The method of making the fold at I8 as illustrated in Fig. 6 with some necessary exaggeration of the thicknesses of the various layers, and similarly the folds at I6, permit a square joint with a firm edge comprising the compacted thicknesses which are formed by the crushing into a sheet-like formation and which bridge over from the relatively remote faces of the connected parts across the edges of the foldably connected sections and provide a firm support for the copper covering which extends unbroken across the fold so made. Moreover, there is no strain placed upon the copper which might tend to crack or tear it.

I havedescribed a preferred form of the invention but it will be understood that a 4building element could be constructed embodying a reverselyl folding butt extension wherein the upper tapered portion was formed in ways other than here described, and` also that the particular method of forming a tapered body herein utilized for forming the upper portion of the shingle might be utilized to form elements not including the feature of the foldable butt.

I am aware thatthe invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not'restrictive; reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
