5 Claims.

' My invention relates to building structures, and includes among its objects and advantages the \provision of a type of outer covering especially adapted "foruse on outer surfaces of buildings, which material can be conveniently manufactured and shipped in relatively large pieces and applied on the site with correspondingly greater ease and dispatch.

In'the accompanying drawings:

Figure l is a vertical section through a portion of the side wall of a building illustrating surfacing material according to the invention applied thereto;

Figure 2 is an outside elevation of the embodiment illustrated in Figure 1;

Figure 3 is an outside elevation of another embodiment; and I V Figure 4 is a section on line i4 of Figure 3.-

In the embodiment of the invention selected for illustration in'Figure 1, I have indicated a plurality of base slabs III directly afiixedto the supporting structure I2 as by nails I4. slabs Ill may be of felted material, such as bagasse or other fibre, either loosely felted only enough to have the desired structural strength, or additionally compressed after felting. Common products of the type suitable for such a base are known in the trade by the name Celotex and Masonite, but many common types of ordinary fibre board could also be employed.

The slabs Ill illustrated in Figure l have plane surfaces in contact with the supporting structure, but their outwardly facing surfaces are formed into the pattern shape clearly indicated in Figures 1 and 2 during the felting operation. After felting, a coating of hot asphalt or analogous material I6 may be sprayed on the base It and while the coating is still hot and plastic, grits I8 may be deposited on and embedded in the coating 16. The horizontal joints in such a wall covering may be formed by the use of a small r-abbet at 20 in the lower edge of the base portion III to receive the flange 22 of the base portion next below, which flange may be fastened in place by the nail I4. I have found that a suitably waterproof joint can be secured in such a construction quite effectively by merely juxtaposing the parts as indicated in Figure l, inasmuch as the abutment between the surfaces of adjacent slabs debouches at 24 sheltered by the overhanging projection immediately above it.

To complete the simulation of shingles, I prefer to separate the gently inclined outer surface portions of the base I!) into individual lands 26 separated by shallow depressions 28 running verti- The base cally, and staggered as clearly indicated in Figure 2. Depending on the taste of the designer, the grooves 28 may be of such a depth that the groove in each land will merge accurately with the inclined surface of the lands below as indicated by the dotted line 30 in Figure 1. Or the grooves may be made shallower as indicated by the dotted line 32 in Figure l, in winch case the finished building will have a continuous line as at 34 in Figure 2 as distinguished from the discontinuous line indicated at 35 in Figure 2.

In Figures 3 and 4. I have illustrated a base slab 33, the surface of which is formed during the felting operation to define a plurality of inclined faces 40 arranged in staggered rows, each face being substantially hexagonal. Such a slab can receive coating identical with that in Figure l, and theresultant exposed surface will look like a roof or side wall covering built up out of individual shingles or strip shingles The outer surface fibres of the base slabs I I3 and 33 will be partially interpenetrated and impregnated with the coating I 6, but most of the body of each base will remain unimpregnated and porous and of high insulating value.

It is, of course, understood that the shapes which may be formed in the base during the felting operation are possible of considerable variety. Shapes may be formed .to simulate most of the well-known roofing patterns as now used.

Without further elaboration the foregoing will so fully explain my invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service.

I claim:

1. An outer covering for buildings comprising, in combination: a porous felted base having one plane face; the opposite face being felted into a plurality of inclined lands; the lower edges of said lands lying substantially in a plane parallel to said plane face; each land, above its lower edge, sloping slightly toward said plane face to define a tapered space with its thinner portion uppermost; each of said lands having an extension extending up past the lower edges of adjacent lands whose lower edges are at a higher level; whereby in horizontal section said base has alternating portions of different thickness, with laterally facing shoulders defining the discontinuities between thick and thin portions; the shape and spacing ofsaid extensions being such as tocause the combined surface presented to simulate the contour of a roof made up of individual hexagonal shingle pieces laid in overlapping relationship; a coating of waterproof asphaltic material overlying the entirety of the irregular surface of said base and bonded thereto by penetration of said coating into the interstices of said base; said coating presenting an irregular outer surface in which the irregularities approximately duplicate those in the irregular base surface; and a surfacing of granular material held in place by at least partial embedment of the granules in said coating, whereby said surfacing also approximately duplicates the surface irregularities of the original base.

2. An outer covering for buildings comprising in combination: a porous felted base having one plane face; the opposite face being felted into a plurality of inclined lands; the lower edges of said lands lying substantially in a plane parallel to said plane face; each land, above its lower edge, sloping slightly toward said plane face to define a tapered space with its thinner portion uppermost; each of said lands having an extension extendin up past the: lower edges of adjacent lands whose lower edges are at a higher level; whereby in horizontal section said base has alternating portions of different thickness, with laterally facing shoulders defining the discontinuities between thick and thin portions;

the shape and spacing of said extensions being such as to cause the combined surface presented a surfacing of granular material held in place.

by at least partial embedment of the granules in said coating, whereby said surfacing also. approximately duplicates the surface irregularities of the original base.

3. An outer covering for buildings comprising in combination: a porous felted base having. one plane face; th opposite face being. felted into a plurality of inclined lands; the lower edges of said lands lying substantially in a plane parallel to said plane face; each land, above its lower edge, sloping slightlytoward said plane face to define a tapered space with its thinner portion uppermost; certain of said lands having extensions extending up past the lower edgesof ad'- jacent lands whose lower edges are at a..higher level; whereby in certain horizontal, sections said base has alternating portions of different thickness, with laterally facing shoulders defining, the discontinuities between thick and-thin portions;

the shape and spacing of said extensions being.

such as to cause the combined surface presented to simulate the contour of a roof made up of individual shingle pieces laid in overlapping relationship; a coating of waterproof asphaltic material overlying the entirety of the irregular surface of said base and bonded thereto by penetration of said coating into the interstices of said base; said coating presenting an irregular outer surface in which the irregularities approximately duplicate those in the irregular base surface; and a surfacing of granular material held in place by at least partial embedment of the granules in said coating, whereby said surfacing also approximately duplicates the surface irregularities of the original base.

4. An outer covering for buildings comprising in combination: a porous felted base having one plane face; the opposite face being felted into an irregular formation to simulate the contour of a roof made up of individual shingle pieces laid in overlapping relationship with shoulders integrally formed along lines cor-responding to shingle edges, certain of'said shoulders lying at an angle to and intersecting certain other shoulders; a coating of waterproof asphaltic material overlying the entirety of the irregular surface of said base and bonded thereto by penetration of said coating into the interstices of said base; said coating presenting anirregular outer surface in which the irregularitiesapproximately duplicate those in the irregular base surface; and a surfacing of granular material held in place by at least partial embedment of the granules in said coating, whereby said surfacing also approximately duplicates the surface irregularities of the original base.

5. An outer covering for buildingscomprising in combination: a porous felted base having one plane face; the opposite face being formed in an irregular formation to simulate the contour of a roof made up of individual shingle pieces' laid in overlapping relationshipwith shoulders integrally formed along lines corresponding to shingle edges, certain of said shoulders lying at an angle-to and intersecting certain other shoulders; a coating of waterproof asphaltic material overlying the. entiretyof the irregular surface-of said base and'bonded'thereto by penetration-of said coating into the interstices of said base; said coating presenting an irregular outer surface in which the irregularities approximately duplicate those inthe irregular base surface; and a surfacing of granular material held in place by at least-partial embedment of the granulesinsaid coating, whereby said surfacing; also approximately duplicates the surface irregularities ofthe original base.
