This invention relates to a Structural assembly adapted for use as siding of; a building and the method of making the'same.

In the making of siding assemblies, such as those having units arrangedin .the manner of clapboards, it has been custbmary, heretofore, to use a supporting substructure including studs and sheathing, with the clapboard units secured over the substructure and forming horizontal overlaps between adjacent courses of the units. When rain penetrates the joints between adjacent courses of the clapboards or the vertical Joints between abutting units in a given course, the water may run downward; uninterruptedly, be-

tween the sheathing and the clapboard facing. There has been another disadvantage in the use of composition boarding that, because of the cost for a given thickness, is commonly available only in clapboardelike units that are relatively'thin, as compared with lumber conventi nally used for the purpose. Namely, when such thin units, of a hardened composition of asbestos and Portland cement or the. like, for example, are assembled, as formerly, in the manner of clapboards, the thinness. of the units 1112- creases the amount of offset between adjacent courses and reduces the resulting shadow effect. to such an extent that artiflciaiity of the structural material is indicated.

It is an object of the present invention to provide a siding assembly overcoming the disadvantages stated above. Other objects and advanillustrated in the attached drawing andtlieilntages will appear from the detailed description that follows.

The'in'vention comprises the novel features of the assemblv. water-impermeable sealing member, andmethod of making the assembly. hereinafterdescribed and illustrated, particularly the means for overcoming the said disadvantages oi conventional assembliegw- "A preferred embodiment of the invention is vention will be described in connection therewith.

There is shown an assembly, adapted for use as the siding of a building or the like, comprising a supporting substructure including studs I that may be wood and units of facing material ar-e "ranged as a plurality of courses 2 and 3, the lower edge of an upper or succeeding course overlapping the upper edge of a lower or preceding course, as illustrated at position 4 (Fig. 1) and 10 as shown in greater detail in Fig. 2. Within a given course there may be a plurality of facing units displaced horizontally with respect to each other and meeting in flush relationship, to form a vertical joint or joints 51 The facing units may be of any suitable type, say, of the asbestos-cement composition previously described. They may be thin, say, about to inch in thickness. The units are preferably' semifiexible, that is, they may be slightly bowed by the means described below. t;

Disposed between thefacing units and the sub structure is water-impermeable sheet material 6, as, for example, asphalt-impregnated rag felt of the type commonly used as roofing paper or so-ca'lled asphalt shingles. This sheet material is flexible and may be folded to give an article possessing appreciable resilience or tendency to straighten out at the position of bending. In my improved assembly, this material constitutes a weather-tight seal that is-suitably continuous over the substructure except at positions at which the'edges of two strips of the material are Plied togethe? as shown at I. Each strip of this material has a folded portion 8 along the top and-a folded portion 9 along the bottom. The folded portions 8 and 9 extend between the overlapping horizontal joint portions ofadjacent courses of facing units with a folded portion 9 of one strip inserted behind the folded portion 8 of the next 40 lower strip. The main portions of the said strips of material are continuous with the folded portions and extend'continuo'usly behind the facing units and the vertical joints 5 therebetween, the sheet material thus forming a sheathing extending between the substructure and all parts of individual ones of the facing units,

-With such a sealingmemberused in my assemblyrwater that penetrates through the V81!- tical joints 5 is deflected to the outside-of the imize rattling and penetration by wind or rain and to prevent a drumming sound when the assembly is struck. Also, the gasket spaces the butt of the units of the overlying course from the underlying course, to give increased shadow effect andappearance of thickness of the facing units, particularly when the folded portion extending between the several courses is of multiply thickness, as illustrated. Finally, this shadow effect is increased and the flexible sealing material is caused to contact closely with the overlapping portions of adjacent courses, when a folded portion of the sheet material is disposed in the h0rizontal joints, because each bend causes thematerial on the two sides of the bend to spread apart and contact resiliently with facing units of the courses 2 and 8.

The means securing the water-impermeable sheet material and the facing units to the substructure are preferably nails or the like. Thus, the water-impermeable material may be secured to the substructure by large-headed tacks or roof ing nails ill extending through the sheet material and into the stud, at a position behind the rear or lower course at a horizontal joint. The said rear course is secured as by nails II to the substructure. These nails ii are driven, also, at the horizontal joint portion but preferably do not extend through the sheet material disposed in the Joint, whereby the sheet material is preserved imperforate and, therefore, is adapted to shed water more certainly than if penetrated by the means I I. Also, there is a considerable space between. the position of the fastening means II and the upper edge of the unit constituting the lower course. When a facing unit is held tightly against the substructure, as by firm driving of the nail ii the facing unit is slightly bowed inwardly toward the position of nailing, this causing the lower edge portion of the facing unit (which extends over and outside a lower course) 'to be deflected away from the substructure and to give thus an attendant increase in the desired shadow effect at the exposed horizontal joint.

The nails Ii have preferably a wide head and pass throughpreformed holes I2 in the facing units.

The preformed holes I! may be slots having each their longest dimension approximately parallel to the general direction of extent of the overlapping portions of the adjacent courses of facing units. In other words, the holes are oversize in one direction but narrow in the direction of the width of the overlapping portions, so that the amount of overlap required to extend safely below the holes is minimized and, on the other hand, lateral shifting of the units, as on expansion or contraction, is permitted.

Finishing nails H, such as those of cadmiumplated steel, or like means may be used to hold the facing units to the substructure at positions below those of the nails ii. The nails I! may penetrate the exposed portions of the units, suit ably, at positions near to but slightly above the overlap between adjacent courses.

The details that have been given are for the purpose of illustration, not restriction. It is intended, therefore, that variations within the spirit of theinvention are to be included within the scope of the appended claims. 1
