WEATHER COVERING MATERIAL Y Filed Mar-ch 10, 1943 Patented Jan. 16, 1945 UNITED s'mcr-lezfsy PATENT OFFICE Donald 'ru110h,Jr.,n0uy oak, nel. l Application Maren 1o, 194s, serial nagaan 6 claims. (o1. 10s-s) This invention relates to composition or rigid Weather surfacing elements, and more rparticularly to roong and siding strips molded from a plastic mass of cement-asbestos or other suitable .composition which sets into hardened or indurated character. verse or vertical ribs or elevations on the weather exposed surface and so disposed to simulateindividual shingles and prevent them from curling.

Generally described, the invention comprises roofing or siding strips which are of substantial lengths provided with transverse or verticalribs or elevations to reenforce the 'strips and prevent them from curling, particularly at the weather exposed butt edge, ends and corners. Moreover, the

The strips are provided with transf numeral l shows a surface, such as a sheathing i of a Wall or roof structure, which is covered with transverse or vertical ribs or yelevationscan be arranged to give a decorative design, such as being spaced apart to set off the Weather exposed surface of the strips in the form of simulated individual shingles or. other decorative designs.` The ribs or elevations may be of gradually diminishlapped courses 2 of strips 3 laid in end to end relation. The strips may be made of any composition usually employed in making tile or other composition shingles or sidingstrips. One preferred composition ywhich* is especially suitable for the invention is a composition composed of cement and asbestos. The mixed mass is molded by conventional vmethods in suitable molds, between forming `rolls or in hydraulic presses,

The strips are oi'indefinite length and width,

but lare advantageously formed in strips equal to about the width of three or four individual shingles. Usually theyy are about thirty-six inches long.

'The' strips .are provided with ribs or elevations 4 transversely disposed at'spaced intervals along the length of the strips; The ribs or elevations ing thickness from the weather exposed butt edges of the strips to the upper or lap marginal edge. They preferably do not extend into the upper or lap marginal edge over which the bottom of ai 'I'he opposite ends of the strips or shingles may 4 be rabbeted :in order that the strips when laid end to end in courses on the rooiing structure Willintert.

For a better understanding of the invention, reference is made to the accompanying drawing,

f inwhich: i l

Fig. 2 is a partial vertical section on line 2 2 of Fig. l;

, Fig. 3 is a perspective view of one of the weather surfacing elements viewed from the upper edge of the element;

Fig. 4 is a partial section on line 4--4 of and Fig. 5 is a perspective view of a weather surfacing element sho-wing a modification of the nailing means.

Referring specically yto the drawing, in which.

tinuous and gradually sloped away at 5 to merge The ribs do not "only for the width ofthe portion which is to be exposed to the weather. They are shown in the present embodimentfof equal elevation throughout their widths, but they may gradually diminish in thickness from the butt edge 'l to the lap portion 8 on the upper face side of the strip. The lap portion is preferably two or more inches wide.

The marginal elevations or

ribs

4a and 4b at the end of the strips `are one half as wide as the intervening ribs or elevations 4, and rib 4a is set back from the edge of the strip while rib 4b projects over the opposite edge of the strip equal to the set back distance of rib 4a. Accordingly the ends of the adjacent strips will intert and form rabbet joints 9 when laid.

Recesses l0 for nails are provided in the upper margins of the strips along the lap which is to be covered by the bottom margins of strips in an overlying course. The recesses for the nails are preferably in medial vertical alignment with the elevations or ribs, particularly the e'nd ribs or between the edges of the 'strips and the areas in the lap which are in alignment with the ribs or elel vations. The nails thus cooperate with the ribs or elevations and in these end areas hold down the-ends of the shingles so that they may be vprevented from curling by reason of the ribs or elevations.

elevations and the nailing may be placed there. The ribs or elevations extenuate the thickness of the lstrips and simulate a more massive appearance.

1n Fig. 5 the nailing means are not in medial vertical alignment with the channels or elevated portions or between the edges and the areas of the lap po-rtion which is in alignment, but are closely adjacent thereto in order that the nailing means may be in position to. cause.. the ribs to prevent any curling of the bottom cornersA of the strips. The outside or extreme end nailing means should be in vertical alignment with the main portion of the ribs or where the ribs merge into the body of the strips. i

Having described the invention and certain embodiments to exemplify it, I claim:

1. A rigid weather covering unit rpxriposed of indurated hydraulic cement composition materia] and having the weather exposed surface dividedl into a plurality of individual shingle simulating areas, an integral vertically disposed por-tionof greater thickness on each marginal end. 0f the unit to reenforce same and prevent the exposed corners from curling, and nailing .portions provided closely adjacent each of the vertical portions o'f greater thickness to cause the marginal ends of increased thickness to prevent the exposed corners of the unit from curling.

2. A rigid weather covering unit composed oi indurated hydraulic cement composition material and having the weather exposed surface divided into a plurality of individual shingle simulating areas, an integral vertically disposed portion of greater thickness on each marginal end and be*- tween adjacent individual shingle simulating areas of the unit to reenforce same and prevent the exposed corners from curling; andv nailing portions provided closelyA adjacent each of the vertical portions ofV greater thickness to cause the marginal ends of increased thicknessto prevent the exposed corners. of the unit from curling.`

3. A rigid weather covering unit composed of v indurated hydraulic cement composition material and having the weather exposed surface between integral vertically disposed marginal portions of greater thicknessthan thel'ortions therebetween toy prevent. the. exposed carriersrof the; unit. from curling, and a nailing portion provided closely adjacent each of the Vertical portions of greater thickness to cause the marginal ends. of increased thickness to prevent the exposed corners of the unit from curling. 1

4. A rigid weather covering unit composed of indurated hydraulic cement composition material and having the weather exposed surface between integral vertically exposed marginal portions of greater thickness than the portions therebetween, ther marginal portion of increased thicknessbeing slightly spaced back from one end of the unit i and the marginal portion of increased thickness being slightly projected beyond the opposite end ,andcomplemental with the opposite end, and a nailing portion provided closely adjacent each of *the-vertical Vportions of greater thickness to cause the, marginal ends of increased thickness to prevent the exposed corners of the unit from curling.

5. A rigid weather protecting covering comprising lapped courses composed of covering units composed of indurated hydraulic cement composition material andhaving the weather exposed surface between integral vertically disposed marginal end portions of greater thickness than the portions therebetween to prevent curling of the weather exposed corners of the units, and nailing means provided closely adjacent each of the vertical thickened end portions and covered by the overlying units, the closely adjacent nailing means preventing the exposed corners of the unit from curling.

6.l A rigid weather protecting covering comprising lapped courses composed of covering units composed of indurated hydraulic cement composition and, having the weather exposed surface between integral vertically disposed marginal end portions of greater thickness than the portions therebetween, said vertically disposed marginalA end portions terminating short of the upper edge to provide a lap., and nailing means provided in the lap closely adjacent the ends of the units and covered by overlying units Whose butt edges are aligned with the ends of the thickened portionsfthe closely adjacent nailing means preventing the exposed corners of the unit from curling.
