PROTECTIVE COVERING MATERIAIQ FOR BUILDINGS.
Application filed May 29, 1922. Serial No. 564,560.
T o U whom. t may concern Be it knoivn that I, IRENE B. l' iin'rs'roNn.
a citizen of the llnited States, residing at Chicago` in the county of Cook and State of Illinois. have invented a new and useful Protective Covering Material for Buildings` of which the following is a specification.
The invention relates to a building material providing a protective covering for s uch surfaces as are exposed to the weather or are subject to wear, as7 for example. the roof, walls and floors in a building.
rlhe primary object of the invention is to produce a material of the character in dicated which presents to the eye a pleasing appearance; is structurally advantageous because of its strength and durability, and because of the facility with which it sheds' water; and at the same time is capable of' economical manufacture.
More specifically, the object is to produce a mterial of the character indicated lin which, by the mere shaping of the surface, or predetermined areas thereof`r to form contiguous alternating ribs and depressions, a shading effect may be obtained which lends a distinct appearance t-o the material, while contributing to its firmness,A durability and general efficiency.
' For purposes of illustration I have shown my invention as embodied in a roofing material of awell known type, but it is Icontemplated that the invention may be embodied in protective coverings used for other purposes and made of various kinds of materials` whether in sheet or strip form. Moreover my invention is not limited to the particular manner of effecting the irregular surface formation herein shown to obtain the desired results for various changes will doubtless occur to those skilled iii the art but without departing from the spirit and scope of my invention, as expressed in the 45 appended claims. i
In the drawings` Figure l is a plan view of a section of a roof having a roofing inaterial embodying my invention applied thereto. Fig. Q is aplan view of my improved 50 material in strip form. F ig. 3 is a fragmentary perspective view illust-rating a preferred form of surface formation to produce a varied color effect.
vof the material for The material selec-ted for purposes of illustration comprises a base 7 in the form of a sheet of felt or the like coated with a plastic bond 8, such as a layer of asphalt. The. latter in turn is coated with a granular material 9` such as crushed slate. This niaterial is of a well known character. To obtain the desired color effectl I employ the principle of shading through the use solely of a` plurality or series of alternating iiidentations or depressions and elevations or ribs. These may 'be of any desired formation and arranged in any desired manner, but prefer to avoid the use of such elongated indentations or depressions as extend for any substantial length over the surface the reason that they tend to weaken the same with a. resulting tendency to curl or warp and to crack when the fastening nails are driven therethrough. l therefore arrange the depressions and ribs in a diagonal .or oblique position upon the strip or sheet preferably spaced apart both longitudinally and transversely of the sheet. Thus as shown in the drawings I have provided alternating grooves 10 and ribs 11 of relatively short length and disposed diagonally or obliquely, and preferably l arrange such grooves and ribs in rows, with the grooves and ribs of adjacent rows oppositely disposed or inclined so as to form pairs to .produce a design after the fashion of a herring-bone. The upper adjacent ends of each pair of grooves are preferably spaced a short distance apart, and their lower ends terminate in a channel or gutter 12 formed longitudinally of the sheet. The special formation of the surface of the material thus provided not only does not weaken the'same but it actually serves to reinforce or strengthen the same and this in both transverse and longitudinal directions. Furthermore, no water pockets are formed but on the contrary free and rapid drainage is ensured. Also, by avoiding the use. of uninterrupted ribs, the material is rendered sufficiently flexible either trans-v versely or longitudinally so as to be capable of being rolled when made in sheet form.
l desire. to emphasize the fact thatwhat l have herein termed as the varied color effect is produced not by the use of different colors in the material itself but b v the use other hand I 'obtain Vthe desired variation solely of a surface formation producing a shaded effect. This renders it possible to` produce a material' superior in character to the roofing material through a printing processor through a process of exposing portions ofthe plastic,
. and either at a substantiallyvincreased cost or at the expense of producing a weakened and generally inferior construction. On the through my invention in color effect without adding perceptibly to the cost-of thev material and with the strength with unrestricted drainage.
In the production `of the material, they means and method commonly employed arel used with the addition only of suitable pressure rolls (not'shown) having formed iny l face of the sheet.
their peripheral surfaces the necessary; ribs and dep-ressionsto produce thedesired formation of the material.A Herein I have shown one surfacey only of the material specially formed, but it will be apparent that both sides may be so formed if desired. The surface forming operation is preferably per! formed as the final operation, and'i'n ,the
, case of the material-shown herein, after thegranular material vhas been applied;
The particular areas in which the surface of the material is specially forme-dv to produce the desired c as desired. Thus it may cover the entire sur- A preferred construction lor effect mayv be varied is that wherein it is applied vto spacedy areas 13 (Fig. 1) producing alternating plain and shaded areas or fpanels, a two-tone effect which presents a strikingly pleasing appearance to the eye. In the event that the roofing is made in'strip form as shown at 14 (Fig. 2), the strips are placed in any suitable way, such asend to end with the upper" edges of the strips slightly overlapped by the lower edges of the upper adjacent strips. It will be apparent that if'it isdesir'ed to 0btain the result shown in Fig. l, with the upper adjacent strip with its plain area directly over the shaded area of the lower strip, this may be accomplished by turning fhe former end for end with respect to the atter.
' It will be apparent that I have produced. l a protective or covering materia-l of an ads.
vantageous character solely through the medium of a special surface formation which when arranged toy produce alternating plain and shaded areas or panels lendsa desirable varied color effect, pleasing to the eye, while at theI same time strengthening;
the material. When employed as a floor covering, the roughened surfaces have the added funct-ion ofv preventing slippage especially when such surfaces are wet."
This application is a continuation in part of my copending application Serial. No.
