Serial No: 21138 3 Claims. (Cl. 20-5) i This invention relates to'coverings for the side walls of houses and the like structures.

The principal object of the invention is to provide elements of a flexible fibrous base water- .6 proofed and weatherproofed in any suitable manner and so constructed as to render them suitable for use as siding material invplace of :wooden clapboard; brick, and similar relatively expensivesiding. 0 ,In order to produce a satisfactory siding material of the character indicated that will be worthy as a substitute for the materials named, the chief considerations are economy of manufacture and ease of application with a amount of material, consistent of course, with adequate protection and pleasing appearance. With the foregoing considerations in View, waterproof flexible fibrous material, as ordinarily fabricated, for example, in the asphalt roofing industry, is illadapted as a satisfactory siding material since the requirements of economy in application make it necessary when 'laying'the material in overlapping rows on a vertical wall or the like, to arrange the rows with; considerable vertical distances between the successive overlapping rows, that is to say with-relatively small overlap between successive 'rows. a consequence, the flexible nature of this type of material, renders the material "objectionable owing to the fact that these large exposed portions are easily blown outwardly by the'wind and they become otherwise readilydisto'rted and unsightly, the fiabbiness of the material when exposed in large sections evidencing' itself more pronouncedly than is the case when relatively smalleryertlcal sections are exposed as obtains on pitched roofs for example.

' By my present invention, the material is so fashioned that the foregoinglobjections are overcome without substantial sacrifice of the required-economy as heretofore mentioned.

In accordance with thefinventioml provide siding strips or" flexible fibrous material suitably waterproofedI 'andin the-form of elongated substantially rectangular body portion's'having' a centrally' located tongue or extensionalong the upper edgeof thejbody portion, the strips as thus configured being adapted to be laid j overlapping rows'with' the longer axisfof the portion in a horizontal direction; and with t tongues extending upwardly so ith at .they will underlie the joints between adjacent strips in the nextwucceeding row; A f f 1 v important featureoftheconstruction af- 3 'forded'by my inventionfthesiding' strips configlowermost edg'egof thestrip.

For thispurpose. the bulking medium preferably comprises an additional layer of Waterproof coating material'of the nature of asphalton-one or-bothfacesof the body portion, within which may beimbedded a layer of crushedmineral of. a color suitable for siding. Advantageously, the additional. layer or layers as above ,described,- are preferablytapered in vertical or transverse crosssection sothat the maximum thickness will be provided, alon the The invention will be more fully understood from the detailed, description to followand from 'the accompanyiii gd awingsin which a t Figure 1 is a plan view.o f av siding strip constructed in accordance with my; invention,

With strips having body portions of greater length, say for example, 36", the length of the tongue may vary from 8 to 18". By making the strips of the aforedescribed, configuration and properly coordinating the dimensions thereof within the limits set forth, greater economy can be effected since the body portions need be only slightly higher than the extent of vertical exposure, the tongues being of such height and width to provide the necessary protection at and around the joints between the strips when laid.

These strips may be severed from continuous sheets of felted fibrous base impregnated with waterproofing saturant such as molten asphalt, and coated on one or both surfaces thereof with a layer of weatherproof material such as high melting point blown asphalt within which may be imbeddedcomminuted or granular mineral material.

Instead of molten asphalt, the coating material applied to the surface or surfaces of the base may be in the form of an aqueous bituminous emulsion made with colloidal mineral emulsifying agent, such for instance, as bentonite. A coating composition of this character is particularly advantageous since the waterfree film thereof possesses the peculiar characteristic of remaining in place without flow under temperatures in excess of the meltingpoint of the bitumen, thus rendering the base more highly fireresistant.

Several modes. in which the strips, configured as above described, may be severed from continuous sheets of the coated and mineral surfaced base, are illustrated in Figures 5 and 6. In both of these methods, I- prefer to employ a sheet of base of a width equal to twice the maximum height of. the strips. The sheet may be slitted longitudinally along its midportion, as

indicated at 20, (Figure 5) or 20a (Figure 6),,

and from each section thus formed, the strips may be severed without waste by means of knives positioned for example, upon a cutting cylinder so as to sever the strips from these sections in reversely arranged or complemental fashion, as indicated by the lines 21 to 25 (Figure 5) or 26 to 34 (Figure 6) defining the boundaries of the strips.

The strips thus severed from the sheet, when applied to the side walls of a building with the greater part of the body portions thereof exposed, would be too flexible and flabby to serve as eflicient and attractive siding material. -In order toadapt the strips for this purpose, I provide the body portions thereof with a weighting qr bulking medium preferably in the form of an additional layer 40 of waterproof coating material and crushed mineral grit embedded therein. This bulking layer may, in some instances, be formed with the exposed face of the strip, but preferably, as shown, it is applied to both the exposed and the underface of the strips. This additional layer of coating and mineral grit may be applied in any convenient way, as for example, by immersing the strips in a bath of the coating material. Upon withdrawal from the coating bath, the strips should be suspended in a substantial vertical position so as -to permit the viscous coating material to drain downwardly towards the lower edge thereof and build itself up in the form of tapered coating with maximum thickness adjacent the lower edge. After the coating material has been applied and permitted to drain sufficiently and take the desired taper, the coated strip may be then contacted with a bed or shower or comminuted mineral matter such as crushed slate or the like, of a color suitable for siding. Preferably, the additional coating layers as thus described, should extend to a line slightlybelow "ing row to a point slightly below the edges 12 of the underlying strips, and hence, the additional coating layer is preferably and advantageously not extended above the line of exposure.

As will be observed, when the strips are severed from the sheet in the manner illustrated in Figure 5, the provision of the bulking layer or layers necessarily constitutes a separate stage in the manufacture. This will be apparent from Figure 5 wherein it will be noted that because of the reversed arrangement of the strips in each section formed by the longitudinal slit 20, coating material could not very readily be confined to the body portions of the strips in the sheet without also additionally coating the tongues, and this is undesirable from the point of view of economy as well as from the standpoint of construction, because of the desirability of having a strip with relatively thin .fiexible concealed portions and with only the exposed portions thereof bulked so as to produce the maximum weight at the lowermost edges thereof. By cutting the strips from 'the sheet in the manner illustrated in Figure 6,

the bulking of the body portions of the strips may be effected as one continuous operation prior to the severance of the strips from the sheet. According to the arrangement shown in Figure 6, the cutting operationfor severing the strips from the sheet is designed to form the body portions of the strips in longitudinal alignment and likewise the tongues of the strips, instead of forming in the same longitudinal alignment body portions and intervening tongues of other strips, as in the arrangement of Figure 5. With this arrangement, therefore, I am enabled to confine the bulking operation to areas which are to form the body portions of the strips. Thus, the additional coating material may be applied to the sheet in longi tudinalbands, such bands being applied along each margin of the sheet and extending laterally of the sheet to lines, indicated at X, spaced slightly outwardly of the lines along which the cuts 27 and 33 are to be made. A similar band of coating material is applied centrally of the sheet and extends laterally to lines indicated at Y, spaced slightly. inwardly of the lines along which the cuts 29 and 31 are. to be made, this latter band being substantially double the width of the marginal bands, so that when the sheet is slit at 20a, the adjacent strips on either side of the slit 20a will carry the bulking layer. These bands of coating material may be applied as by means of sprays or coating rolls, either to one or both faces of the sheet, and any convenient means may be coating material to the sheet in spaced longitudinal bands, an important feature is the confinement of the bands within the transverse areas of the sheet out of which the body portions of the strips are to be cut, so that the coating material will be precluded from flowing over onto the portions of the sheet from which the tops of the tongues of the oppositely disposed strips are formed, in which event the additional coating layer along the topmost portion of the tongues would tend to elevate the overlying strips at these points, when laid, thereby detracting from the sightliness of the completed side wall construction.

The strips formed by either of the methods herein described will be arranged in successive overlapping rows with the strips of each row breaking joints with those of the preceding row, as shown in Figure 3, and with the lower edges 17 of each strip spaced a slight distance below the upper edges 12 of the body portion of the strips ,in the next preceding row so as to expose the greatest part of the body portion, as is necessary in order to realize the required economy. By virtue of the fact that the tongues 13 are equal in height to the body portion, the amount of vertical overlap between succeeding rows will leave an equal vertical portion of the tongues to project above the upper limit of the joints between adjacent shingles in the next succeeding row suflicient to preclude leakage there- I through.

In applying the strips to the side wall of a building, I prefer that they be fastened thereto by nails driven through the strips at points slightly below the upper margin of the bulking layer 40, and in position to be concealed by the overlying strip. By thus nailing the strips through the thickened portions thereof, instead of through the portions not formed with the bulking layer, greater resistance is offered to raising or blowing up of the exposed portions under the action of the wind.-

Having thus described my invention, it will be manifest that numerous variations and changes maybe made therein without departing from the spirit of the invention as set forth in the appended claims.

I claim as my invention: v

1. A side wall covering simulating clapboard, comprising a plurality of overlying courses of asphalt coated and grit surfaced felt base elements of maximum thickness at their lower edges, having body and tongue'portions, the length of the body portion being at least three times the exposed depth thereof, the tongues extending upwardly from an intermediate point of the upper edge of the body portion for a distance substantially greater than the exposed depths of the body portions, the elements in the same' course being flush and the body portions of each course overlapping the body portions of the subjacent course for a distance substantially less than the depth of the exposed body portions.

2. A wall covering comprising a plurality of overlying courses of asphalt coated and grit surfaced fibrous base elements, each element being thickest at its base and composed of a body portion and a tongue extending centrally upward from the body portion for a distance greater than the depth of the exposed portions of the body, the length of said body portion being at least three times as great as the depth of the exposed portions, the tongues of the elements in each course lying under the elements of the adjacent overlapping course at the meeting places of the side edges of adjacent elements of the same course and each course overlapping the body portions of the elements of the adjacent underlying course for a distance substantially less than the depth of the exposed portion of said elements. 3. A side wall covering simulating clapboard, comprising a plurality of overlying courses of elements each of which has a body portion and atongue portion of less length than and equal in height to the body portion, the body portions of adjacent courses overlapping for a distance substantially less than the depth of the exposed body portions, and the tongues of each course being positioned to underlie the next succeeding course for a distance greater than the distance of over lap between body portions.
