ROOFING- MATERIAL.

T 0 all whom it may concern:

Be it known that I, MORRIS H. Envmon, a citizen of the United States. residing at New York, in the county of New York and State of New York have invented certain new and useful Improvements in Roofing Materials; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to roofing material in sheet or strip, and also in shingle form. It has for its object to form the material with its exposed or weather surface formed of broken or granulated particles of slate of different contrasting colors arranged in parallel areas of irregular width and merging at their termini in either converging or diverging cross area into other like extending areas which are of colors contrasting with those merging into the same, some of the areas being a blend or mixture of the contrasting colored areas made up of more or less of the colored contrasting materials of which the contrasting areas are formed. With the different colored slate material applied as stated there is produced an exposed or weather surface to the roofing material of manifold colors in distinctive areas differing from one another in color and outline and extent of area with no fixed or predetermined clearly defined shape, configuration or design so that the surface as a whole presents a soft, diversified, multiform assemblage of distinctive colored areas relieved from the monotony of sameness and thus imparting life and freshness due to the assemblage of areas of color and devoid of the dullness and appearance of age due to monotony of sameness of color and staid and set lines characteristic of fixed designs of outline or configuration, and consequently the discontent and desire to change the roof because of becoming tired of monotony in its appearance is avoided and the expense of providing a new roof is saved. Furthermore, when the roofing material is cut into forms of shingles and applied to a roof, each shingle has some of the characteristics of the material in sheet form and the aggregation of the shingle units on the roof gives the 1922. Serial No. 558,430.

effect of the colored areas in the sheet form of the material with substantially the same diversified coloring and contrasts and freedom from monotony of staid designs, with no two shingles having exactly the same contrastmg areas except such as may occasionally occur from the accidental coincidence of two being very much alike but then with some differences appearing upon closer comparison of one with the other.

The accompanying drawing gives an illustration of an embodiment of my invention in both sheet form and in the form of shingles, and in which Figure 1 is a perspective plan view of the sheet form of the roofing material;

Figure 2 is a plan view of Figure l on a somewhat larger scale, with a portion broken away, and illustrating by longitudinal and cross lines, the division of the sheet material into shingle units;

Figure 3 is a side elevation illustrating the manner of applying the individual or unit shingles to a roof;

Figure 4 is a perspective view of three shingle units, each showing the contrasting color areas as occurring in each when out from the sheet form of the roofing material.

In forming the roofing material, the fibrous fabric base is saturated or impregnated with the waterproofing composition, and then after the surplus waterproofing compound is squeezed from the fabric, an adhesive coating of pitch or asphaltum is applied to one surface of the fabric, before the mineral substances are deposited on the adhesive surface, and after the mineral substances are applied to the adhesive surface the fabric is then passed between rolls, and finally cut into shingle units if that form of using the roofing material be preferred. The means for carrying out the steps thus generally stated may be any of the well known form of machines commonly employed fonmaking sheet roofing material with a mineral substance applied to one surface, with such modification in the manner of placing the mineral substances in the hopper from which they are fed ordischarged onto the traveling fabric base that the mineral substances will assume the position or arrangement in relation to one another contemplated by the present invention. In practice I make use of three primary colors of broken or crushed slate, say red, green,

and what is commonly known as blue-black slate. These different colored slates, in crushed or comminuted; condition, are placed in a hopper in separate batches of red, green and blue-black, with one colored slate superimposed upon another color, with the colors in each batch preferably alternating one with the other, and each batch, having substantially the same depth or thickness as the other batches, or the batches differing from one another in depth, so that there may be a greater quantity of one than another so as to produce greater diversity and lack of sameness between the various areas of colored slate on the finished surface of the roofing material. With the same purpose in view there may be different colored slates placed side by side in the hopper as wellas having superimposed layers or batches of colored slate in the hopper, and as the crushed slate may settle in the middle portion of the hopper faster than at the sides there may be a running together to a greater or less extent of different colored slates at the point of discharge from! the hopper, or the hopper may empty of one colored slate before another and that be followed b a slate of another color, so that there wi I be produced the diversity of colors and diversity in areas of colors sought under the present invention. It is of course to be understood that the slate Will be delivered from the hopper in a thin stream'of uniform density and so as one edge to the other of the which it is deposited, any

of discharge valve to the hopper being provided for the purpose and which does not constitute a feature of this invention. As above indicated the crushed slate of contrasting colors is deposited on the traveling fabric base so as to cover the entire surface of the fabric and produce distinct contrasting colored areas of varying or diversified extent both as to length and width, some of the b areas converging in one direction while others diverge in the same and one merging into the other at the termini of the areas and likewise merging into the parallel areas so that the maximum of diversity both as to areas and as to extent of each area is obtained. For instance, as illustrated in the drawings, the green colored slate area is indicated by the diagonally extending lines; the blue-black slate area by longitudinally extending lines; the red slate area by vertically extending lines; and the mixture or blend of two colored slates b the lines which cross each other, the blend of green and blue-black by crossing of the diagonal and longitudinal lines; the blend of green and red by crossing of the diagonal and vertical lines; and the blend of blueblack and red by crossing of the longitudinal and vertical lines, The extent of each area to extend from. fabric base onto. well known type .h

general direction may vary 'both longitudinally and transversely of the roofing'fabric base according asthe granulated material may feed from the hopper, and according to the longitudlnal extent of each area one area will merge into another area at the termini of theareas, and at such points of merger one area may converge and the otherarea alongside thereof may diverge, and the lines of convergence and divergence may be in opposite directions as indicated in the middle portion of the fabric base as illustrated in Figure 2 of the drawing. The purpose of this variation in the areas of distinctive contrasting colors and blending colors has been'hereinbefore stated.

When the material is to be applied in shingle instead of sheet form, the sheet is subdivided into shingle lengths or units as indicated by the heavy longitudinally and transversely extending lines illustrated in Figure 2 of the drawing, and when this is done it will be observed that each shingle or unit differs in some specific details from all the other units although each will contain some one or more characteristic features of the others. Merely for purposes of description and clearness of illustration as to diversity of contrasting colored areas when the shingle units are assembled in a shingle type of roofing, I have indicated the various shingle subdivisions or units in Figure .2 of the drawing, each, by a letter of the alphabet, the letters alternating in consecutlXG order, and in Figure 3 of the drawing I units as they may be assembled on a roof, the individual units in Figure 3 being alphabetically designated but in different order of sequence from the illustration in- Figure 2 so that a better understanding may be had of the diversity of varied contrasting colored areas obtained under my invention, it being understood that the shingles may be assemled and placed on the roof without regard to any predetermined selection of individual units so that entire lack of sameness in the roof as a whole may be obtained both in the roof itself and in the roofs of different buildings.

three shingle units selected to indicate the different distinctive contrasting colored areas and the blended colored areas, or portions thereof, as they may appear in the different units, and I have indicated by appropriate lettering the respective areas appearing in each.

The objects sought and actually accomplished will be understood from the foregoing description and the merits of the invention and its advantages will be obvious by a consideration of the special features of of arrangement or disposition of the contrasting areas, and its marked differences or ave given an illustration of the shingle i In Figure 4 of the drawing is illustrated characteristics over prior roofing material in both sheet and shingle form will be appreciated by the skilled in the art.

Having described my invention and set forth its advantages, what I claim is:

1. A roofing material having a granular material Weather surface characterized by contrasting colored elongated areas of irregular length and Width and merging at their termini into other contrasting colored areas, some of the areas converging and others diverging at the points of merger of the areas, and areas of blended colors intermediate of the contrasting colored areas and formed of a mixture of adjoining contrasting colored $885.

2. A roofing material having agranular material Weather surface characterized by contrasting elongated areas of irregular length and Width and merging at their termini into other contrasting colored areas, some of the areas converging and others diverging at the points of merger, the material being subdivided into individual units to produce When assembled a composite roofing possessing in the aggregate the characterisgiics1 of the contrasting colored areas specie In testimony whereof I afiix my signature two witnesses.
