- 11 Claims.

This invention relates to improvements in building covering members, and particularly to material of this character comprising a panel of rigid composition board of compressed cellulose bers coated with waterproof material and surfaced to simulate the'appearance and texture of a section of a masonry wall.

rl`he use of this type of building covering material has proven successful by reason of its substantially permanent decorative exterior, insulating properties, and other desirable characteristics. However, considerable care must be exercised to insure proper application thereof to a building by reason of certain of its character- 15 istics. Thus, in applying the material, which is commonly nailed to place, with the nail piercing the waterproof vouter protective coating, it is essential that lthe nail head and nail hole be thoroughly sealed to prevent seepage of water about the nail and past the waterproofing material to the composition board. -This for the reason that the composition board is highly porous and absorptive, and swells, weakens anddeteriorates when wet. Another condition to which members of this character have been subject, is the driving of a nail too deeply into the board which is of substantially laminated compressed fibrous character and contains no binder or like medium to afford homogeneity and strength. Thus a nail driven too deep tends to rupture the board. Still another condition to which such members are subject is the absence of any substantial mechanical or friction bond between the panel and a nail, by reason of the structural character of the composition board which makes eiiective securing of the member difficult and endangers the seal effected by coating the nail head. Likewise, the character of the composition board requires close spacing of nails to insure solid securing of each panel to the frame.

It is, therefore, the primary object of this invention to provide a building covering member wherein the aforementioned difficulties are eliminated and the product is constructed to minimize possibility of failure.

A further object is to provide a building member of this character provided with pre-formed nail holes.

A further object is to provide a building member of this character having a base of composition board provided with preformed nail holes and saturated with waterproong material adjacent all surfaces thereof including the walls of sad nail holes.

A further object is to provide a composition board product of this character of increased strength and rigidity and with insulating prop erties substantially unimpaired. A

A further object is to provide a building member of this character comprising a surface satu- 5 rated ccmpositionboard having preformed nail holes, and a waterproof coating normally sealing the outer ends of said nail holes.

A further object is to provide a building member having preformed nail holes sealed at their 10 outer ends, with means indicating the position of said nail holes.

A further object is to provide a building member of this character which is strong and thoroughly waterproof, which requires fewer nails, 15 and which will eiectlvely grip nails.

Other objects will be apparent from the description and appended claims.

In the drawing:

Fig. 1`is a face view of my improved building 20 member.

Fig. 2 is a fragmentary enlarged sectional view taken on line A-A of Fig. 1.

Fig. 3 is a fragmentary enlarged sectional view similar to Fig. 2 and illustrating the manner of 25 nailing the member.

Fig. 4 is a fragmentary enlarged sectional view of the saturated composition board base with a preformed nail hole.

Fig. 5 is an enlarged fragmentary sectional view 30 similar to Fig. 2 illustrating a modified construction of building member.

Referring to the drawing, the numeral I0 designates a building covering member having marginal ship lap flanges I I and a coated contoured 35 face provided with longitudinal and transverse narrow elongated depressions I2 arranged to simulate mortar joints and separating surface areas simulating masonry members such as bricks I3. 40

The member is preferably formed on a base best illustrated in Fig. 4, which constitutes a rigid panel I4 of composition board of compressed cellulose fibers, such as Celotex and the like. A plurality of spaced narrow holes I5 are formed 45 in and extend through the board I4 in predetermined relation and arrangement. The lentire surface portion of the board' is saturated to a comparatively shallow depth with Waterproof material such as asphalt I6, said saturant also 50 saturating the board at I'I at the walls of each hole I5. Composition board is of compressed laminated fibrous character whereby it has substantially greater porosity at its edges than at its faces, whereby the transversely extending satu 55 rated portions, as at I'I around holes I5 are of greater depth than face portions iii. This effectively reinforces the board at its weakest points, as around ship lap flanges il, and also serves to form a binder for the laminations of the composition board around each nail hole. The saturant preferably penetrates to only a shallow depth sufficient to provide the improved structural and Waterproof characteristics without impairing the insulating properties of the composition board to any material extent.

The preferred composition board above described may be treated and finished to provide any of several well known types of iinished product. One such type is illustrated in Fig. 2 wherein a continuous surface layer or coating I8 of asphalt or like waterproof material is applied to one face of the' preformed panel; and colored granular material or grit I9 is applied to coating I8. This coating is suitably pressed to provide the depressions I2 therein, and thus achieve the masonry simulation. The depressions are preferably located to coincide with the various holes l5 in the board i4, and the formation thereof tends to iorce the coatingmaterial into the upperends of holes i5 to a substantial extent at 20, as illustrated in Fig. 2. At the same time the depressions l2 are 'ormed as by suitable dies, indentations 2l may be formed in coating i8 in registering relation to the holes i5. In applying this type of member to a building, the panel is applied dat against a building as against studding, sheathing, siding or the like, and nails are driven therethrough at holes i5 and into the building. The nail heads seat in depressions and are completely protected and concealed by waterprooing material at 2d.

Another embodiment of the invention is illustrated in Fig. 5, wherein the preformed partially saturated composition board i@ is illicwise coated with a comparatively thin continuous layer i8 of adhesive waterproof material sealing one end or" holes i5 at 2@ and indented at 2l in registration with each hole i5. in this construction, however, the coating l@ serves to cause thin slab units Z5 of brick, stone, asbestos composition or the like to adhere to the base in spaced patterned relation. Nails are adapted to be driven through holes i5 in the spaces between slabs 25 to secure the unit to a building as heretofore described, and the spaces then being lled with mortar or like material (not shown) which conceals the nails and completes the surface.

It will be seen that, with both above described types of construction, the nail pierces the portion 2U of coating I8 in holes i5 and passes through said holes in the member without ex posing or contacting an unsaturated portion oi the board. The increased depth of penetration of the saturant at areas il' around holes i5 insures against such Contact of the nails with unsaturated portions of the board even when the nail is driven at an angle to hole i5; and also serves as a reinforcement to prevent damage to the board if a nail is driven so deeply as to lodge its head below the upper surface of the base. The nails employed are preferably of slightly greater'thickness than the transverse dimension of holes i 5 so as to insure a tight ht of the nails with the board, and the saturant il around the holes I5 insures a binding or adhesive contact as well as a frictional t between the nail and board. In addition, the saturation of portion I'i around the nail increases the strength of the board where it is nailed and insures solid effective anchoring of the unit to the building when nailed. In this way fewer nails are required to secure my improved member solidly to a building than are required to secure a conventional unsaturated member of the same character and size. Furthermore, in the event fewer nails are employed than provided for, the unused nail holes I5 remain permanently and effectively sealed in weatherproof manner by portions 20 of coating i8 at the outer ends of said holes, so that the presence of such holes will not detract from the Weatherproof character` of the building member. The indentations 2i which indicate the locations ofsuch unused nail holes are small and inconspicuous, and these factors coupled with the location of the indentations in depressions i2 does not detract from the general appearance of the members and renders the presence of unused nail holes therein unnoticeable when said members are applied on a building. It will, of course, be understood that one of the prime advantages of this construction is the retention of the insulating value of the base by retaining the major portion thereof unsaturated, while at the same time preventing moisture from entering the unsaturated interior of the'body by way of the nail holes. T n this connection, it will be noted that the construction is particularly effective with the type of construction shown in Fig. 5 where the slabs render each building unit quite heavy land nailing of the unit tends to de form the board around the hole and to enlarge the hole by reason of said weight, all of which is avoided by the saturation reinforcement of the base as described. Additionally, the Fig. 5 type of construction contemplates the use of regular mortar between slabs without coating the nail heads, the moisture from the mortar thus being directly accessible the points of nailing, so 'that any iooseness between nail and member in conventional construction permits the moisture to enter the same, whereas all such dangers are eliminated by the instant construction.

For the purpose of stabilizing the product, the saturating agent employed is preferably an asphalt having a comparatively high melt point and substantially free from volatile solvents, and the coating lil is formed oi like material. In this way all possibility of chemical action between the coating and saturant, such as permeation of coating iii by solvents which dilute the body thereof or impair the adhesive qualities thereof, is avoided.

Attention is also directed to the fact that, with respect to the feature of the tight sealed fit between the board and nails and the waterproof character of the board around the nail, it is possible to avoid or eliminate use of coating 24 over the nail head in the Fig. 3 type of construction, by using rust proof nails of the same color at their heads as the coloi` or coating i8, usually black. In other words, the construction is so sealed around the nail that protection of the board by such coating is unnecessary, and the color problem for concealment of the nail is all that must be considered.
