Serial No. 112,814.

This invention relates to fabricated roofing of a type whichis commonly made of a base of felted fibrous sheet material saturated with a waterproofing asphaltic compound and coated with layers of impervious material,

such as blown or high melting-point asphalt and granular material.

In the manufacture of roofing elements of this type, material for the base is usually made from a pulp ofrag, asbestos or other suitable fibers, and formed into sheets on-a papermaking machine. This felted fibrous sheet material is preferably saturated with an asphaltic compound, the saturant either being mixed with the pulp in the form of an emulsion, or applied in liquid form to the dried sheet. one or both sides with a suitable coating compound, such as blown asphalt which, by reason of its tough rubbery consistency at ordinary atmospheric temperatures and its relatively high melting point, is generally used for this purpose. To protect the asphalt from the deteriorating action of the weather,

it may be surfaced with suitable granular or comminuted material, such as crushed slate, tile, brick, or the like. Pulverulent material, such as .powdered mica or chalk dust,- may be substituted for the granular material on areas which are not exposed to theflweather when the element is laid, to prevent adjacent 7 elements from sticking together when packaged for shipment. The roofing elements are then cut or otherwise separated from the sheet, being given any, desired size or shape. Such elements ,may be individual shingles or may be strip shingles, so called, .with a plurality of tabs simulating individual shingles. This method of making roofing elements is capable of considerable variation both in so quence of the various steps and in the mannerof carrying out each step. By whatever process the elements are made, there is bound to be a certain percentage of seconds or elements with imperfections of onekind or another which prevent'their being sold in the form and grade intended. The imperfections in such elements are often slight, and of a nature which in no way detracts from the protective qualities of the element. By my The saturated sheet is then coated on invention, I am able to reclaim and utilize a large proportion of seconds and thus prevent a-large waste of costly material. This may be done by cutting or tearing material from the butt edges or portions of the elements so as to remove the imperfect parts and at the same time produce an element which will have irregularities of shape which offer great possibilities :for artistic efi'ects, avoiding the monotonous regularity which characterizes elements of uniform shape when laid on a roof. Y

After cutting or tearing the elements to irregular shapes, I may apply an additional coating of blown asphalt or the like to the whole surface or the exposed portion thereof, this coat also covering and sealing the cut edges. A surfacing of granular material may-then be applied to the coat, this granular material being of a number of colors if desired. Where a plurality of colors are used,

it is preferred that each color occupy a definite area substantially coextensive with that portion of a shingle strip which corresponds to an individual shingle. The additional layer of asphalt and grit also covers surface imperfections and adds materially to the thickness of the element, thus giving it a more substantial appearance.

My invention is not to be limited to the reclamation of factory seconds, as I may start, with the coated and slated sheet material, cut or otherwise separate elements therefrom with irregularly shaped tabs, then apply an additional-coating, sealing the cut edges, and surface the coating with grit which may be of a variety of colors arranged as hereinbefore described.

Further advantageous features will be apparent from the disclosure in the description which follows, and from the drawings, of

' which,

Figures 1 and 2 illustrate strip shingles I having tabs of different geometric shapes and different colors.

Figure 3 indicates the effect produced by a number of such strip shingles laid in overlapping courses. I

, Figures 4 and 5 show in cross section two examples of the structures which may be ferent shapes. The extensive cut-away por-- tions make this type of strip shingle particularly valuable in the reclamation of factory seconds which may have slight imperfec tions such as cuts or tears in one or more of the tabs. The forms illustrated in these figures are illustrative of a large variety of combinations of shapes which can be made. In addition to various shapes for the several tabs, it is preferred to have a variety of colors, each color being confined to a portion of the strip shingle which corresponds to one tab. Thus in Figure 1, for example, a three-tab strip shingle is shown, one of the tabs 10 being pointed, another tab 11 having a semi-hexagonal shape, while the third tab 12 is semi-circular. These different tabs are surfaced with solid colors, the color of each tab being different from that of the adjacent tab. In reclaiming defective strip shingles, the defective portions may be cut out in any convenient manner so as to form tabs of desired shape, the shape being governed somewhat by the nature and extent of the defects. After the strip shingle has been cut to shape, it may be coated with suitable impervious material, such for example as blown asphalt or the like, this coating being applied over all the surfaces and edges of the element, or merely to the exposed surface and edges, or to any extent between these. While the coating is still hot and sticky, granular material of any desired kind, such as crushed slate, brick, tile, or other equivalent, may be applied, grit of different colors being used for the several tabs of the element. Figure 4 shows in cross section a refinished element comprising a fibrous core 13 of felted sheet material, preferably saturated with liquefied or emulsified asphalt. On either side of this felt sheet is a coating 14 of blown asphalt or the like, surfaced'with grit 15 on both sides of the element. The refinishing coat 16 of blown asphalt covers the grit layers 15 and extends in a continuous film around the butt end of the element as at 17. This outer coating of asphalt is overlaid with a second layer 18 of grit which may be applied to the upper and lower surfaces of the element as shown, orsimply to the upper surface and the edge. Figure 5 is a section similar to Figure 4 showing a refinished element which originally was coated on both sides with layers 16 of blown asphalt, but was finished with grit 15 on one side only. As previously described, a second coating of blown asphalt may be applied over the exposed surface and edges, or over the entire surface of the element, the r-ecoated portions being re-surfaced with an additional layer 18, different colors of grit being preferably used for the several tabs. It will be apparent that many variations are possible in the extent of the portions coated and surfaced with grit in the refinishing process, the examples given in Figures 4 and 5 being by way of illustration only.

Figures 6 and 7 illustrate two varieties of strip shingles which are made up to give an appearance of irregularity and roughness to the roof as a whole. The tabs on the element shown in Figure 6, for example, may be shaped by cutting or tearing so as to resemble the projecting ends of rough slabs of stone or tile. In the form illustrated in Figure 7, the usual straight line edges of the tabs are relieved by wavy or jagged lines, the regularity of effect being further eliminated by the difference in width of the tabs. In these forms also it is preferable to apply the final surfacing layer of grit so that each tab will have a solid color different from other tabs in the strip, although if desired two or more adjacent tabs may now and then be given the same color. When strip shingles are made up with tabs,of unequal width as in Figures 6 and 7, it is preferred to regulate the widths of the tabs so that they will be limited to either thirds or fifths of the standard width. When laying such elements on a roof, the elements in successive courses should be offset laterally a distance equal to half the standard width of a tab. This will avoid the possibility of a slot between tabs of one element coinciding with the line of abutment between adjacent elements in the course below, a situation which would reduce the protection afforded by the roofing elements and would be liable to cause a leak at that point. By regulating the widths ofthe tabs as stated; such a contingency is avoided and all abutting lines of adjacent elements are covered by some portion of a tab, thus insuring complete protection.

It is to be understood that the invention is not to be limited by the embodiments shown and described herein, but is subject to such changes and modifications as fall within the scope of the appended claims.

I claim:

1. The process of refinishing strip shingles having shingle-simulating tabs, which comprises tearing away portions of said tabs to alter the original shapes thereof and to produce irregularly shaped edges, coating the exposed surfaces of the element with an impervious compound, and surfacing the coated areas with comminuted material.

2. The process of refinishing imperfect strip shingles haying shingle-simulating tabs, which comprises re-shaping said tabs into a variety of shapes by the removal of portions thereof, coating the exposed surfaces and edges of the element with an impervious compound, and applyin granular miterial of difl'erent colors to t e several 'ta s. i

3. The process of refinishing shingles, which comprises tearing away portions of the butts to alter the original shapes thereof and to produce irregularly shaped butt edges coating the exposed surfaces and edges of the shingle with an impervious compound, and surfacing the coated areas with comminuted material.

In testimony whereof I have aflixed my signature. FREDERICK C. OVERBURY.
