BUILDING COVERING MEMBER. Gilbert J. Snyder, ISouth Bend, Ind., assi'g'nor to Mastic Asphalt Corporation,

South Bend, Ind.,

a corporation of Indiana Application April 22, 1939, Serial No. 269,542 In Canada November 14, 1938 2 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 coatedl with waterproof material and Surfaced to simulate the appearance and ,texturev in that they have a tendency to peel, especiallyA when struck or pulled at an edge. This is a denite peeling or delamination of the board itself, as distinguished from a separation of the coating from the board.- Asphalt hasl a stronger adhesion with the board than the adhesion between fibrous constituents of the board, hence the delamination above mentioned. Also, the asphalt is iiexible, and this quality enhances and ncreases the likelihood of delamination, especialy when once started at an edge of the panel, as when the same has been struck.

It is, therefore, the primary object of this in- Jention to provide a building member formed of :omposition board and coated with asphalt or ;he like, wherein the tendency of the board to :eel beneath the coating when struck at its edge s substantially completely eliminated.

A further object is to provide a member of his character wherein the outer surfaces of 'the )card are surface saturated to bind the fibers hereof and rigidify and strengthen the board.

A further object is to provide a composition Joard product of this character of increased .trength and rigidity and with insulating properties substantially unimpaired.

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

Referring to the drawing, the numeral I0 designates a building covering member having marginal ship lap iianges II and a coated contoured face provided with longitudinal and transverse narrow velongated depressions I2 arranged to simulatemortar joints and separating surface areas simulating masonry members such as bricks I 3 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 iibers, such as Celotex and the like. A plurality of spaced narrow holes I5 are formed in and extend through the board I4 in predetermed relation and arrangement. The entire surface portion of the board is saturated to a comparatively shallow depth with waterproof material such as asphalt I6, said saturant also saturating the board at Il at the walls of each hole I5. lComposition board is of compressed fibrous character whereby it has substantially greater porosity at its edges than at its faces, whereby the transversely extending saturated portions, as at" I'I around holes I5 are of greater depth than face portions I 6. This effectively reinforces-the board at its weakest points, as around ship lap anges Il, and also serves to form a binder for the laminations of the composition board around each nail hole. The saturant preferably pene'- trates to only a. shallow depth suilicient to pro-- vide the improved structural and waterproof char.

acteristics without impairing the insulating properties of the composition board to any material extent..

'I'he preformed composition board above described may be treated and finished to provide any of several well known types of finished 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 ofthe preformed panel; and colored granular material or grit I9 is applied to coating I8. 'I'his 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 l 5 in the board I 4, and the formation thereof tends to'force the coating material into the upper ends of holes l5 to a substantial extent at 20, as illustrated in Fig. 2. At the same time the depressions I2 are formed,'as by suitable dies, indentations 2| may be formed in coating I8 in registeringrelation to the holes I5. In apply-A ing 'this type of member to a building, the panel ls applied fiat against a building 22 as against studding. sheathing, siding or the like, and nails 23 are driven therethrough at holes I5 andintc holes I5 at 20 and indented at 2i in registration with each hole I5.. In this construction, however, the coating Il serves to cause thin slab umts 25 of brick, stone, asbestoscomposition 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, the space then-'being illled 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 20'01 coating I8 in holes I5 and passes 'through said holes in the member without exposing or contacting an unsaturated portion f the board. The increased depth of penetration of the saturant at areas i1 around holes I5 insures against suchcontact 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 I5 so as to insure a tight fit of the nails with the board, and the saturant I1 around the holes I5 insures a binding or adhesive contact as well as a frictional fit 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 securev my improved member solidly to a bullding 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 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 of such unused nail holes are small and inconspicuous, and these factors coupled witrgthe location of the indentations in depressions I2 does not detract from the general apinvention is illustends to deform 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 vbase 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 at the points of nailing, so that any looseness 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, an the coating I8 is formed of like material. In way all possibility of chemical action between the coating and saturant, such as permeation on coating I8 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 ilt 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 color or coating I8, usually black. In other Words, the construction is so sealed around the nail that protection of the pearance 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 re-l taining 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. In this connection, it will be noted that the construction is particularly effective with the type of construction shown in Fig. 5 where the slabs 25 render each building unit quite heavy and nailing 'of the unit board by such coating is unnecessary, and the v`color problem for conceahnent of the nail is all that must be considered.

The surface saturation of the composition board binds together the surface fibers of the board and rigidies the same. The saturation underlying the coated face cooperates with the coating to rigidity the same; while that at the edges resists separation of the bers and damage to the board at its edges. B oth thus serve positively to minimize possibility of delamination of the board by peeling of the coating therefrom.

I claim:

l. A building covering member comprising a rigid composition board formed of compacted brous material which is subject to peeling when coated with flexible plastic material, waterproof material impregnating said board to ashallow depth at all surfaces thereof whereby the fibrous material at yall `edges of said board is rmly bound together, and a coating o'f bituminous material covering one surface of said board, the `depth of impregnation of the board portion underlying said coating being 'sufcient to substantially increase the rigidity of said portion and the coating adhering thereto and thereby resist peeling of said board, the major portion of the board being unsaturated to substantially retain the insulation properties of thevboard.

2. A building covering member comprising a rigid composition board formed of compacted flbrous material which is subject to peeling when coated with flexible plastic material, a coating of flexible plastic waterproof' material covering one surface of said board, and adhesive material binding the fibrous material of the board at all edges thereof to resist peeling of said board without substantially impairing the insulation properties of the board.
