CHARLES L. KELLER, or WYOMING, onrof ROOFING.

Specification of Letters Patent.

Patented Aug. 3, 1929.

Application filed September 22, 1919. serial No. 325,340.

To all whom it may concern:

Be it known that I, CHARLES L. KELLER, a citizen of the United States, and a resident of Wyomin in the county of Hamilton and State of @hio, have invented certain new and useful Improvements in Roofing, of which the followin is a full, clear, and ex act description, re erence being had to the accompanying drawings, forming part of this specification.

My invention relates to roofing materials made up from composition material such as a fibrous body with a slate surfaced waterproof asphalt coating or of'equivalent composition roofin In the use 0% such material a well developed art has sprung up in recent years, both in the use of individual shingles or tiles made up of composition, and in the use of strips of material cut out and laid so as to giv; a shingled or tiled appearance to the roo My invention involves among other things a method of centrally cutting, or cutting between the edges of a strip of such material whereby no loss of the material is involved, and strips provided thereby, which may be employed so as to give a wide ran e of effects, while still providing a watertlght and weatherproof roof. It also involves a new form of tile and roof provided thereby, and a new method of cutting out the separate pieces from a long strip of prepared material, whereby the laying of the pieces can be done in a wide range of manner, and without leakage at any joints.

In addition to these advantages I am enabled to expose a greater percentage of the strip when laid on the roof, and thereby work out more economical use of the material. In other words, not only the tabs but also greater parts of the body are exposed than is the case of any strip shingle within my knowledge hitherto produced.

Besides this advantage, I am also able to break up the monotony of the present styles of shingles by achieving the effect of large and small slabs, and slabs of different shapes which has never been attempted with strip shingles before, to my knowledge. In other words, by using my strips and varying the method oi laying, I am able to produce roots of varied efi'ects.

In these oft-acts I prefer that two edges of extensions or depressions always to-= gether, raising the roof at these points in a waIy' never obtainable with other strips.

accomplish the above noted features with their attendant advantages as will be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 shows a preferred form of centrally cutting a piece of roofing material.

ig. 2 is a view of a roof construction made up of strips taken from the one side on? of the cutting shown in -1.

ig. 3 is a view of a roof made only from the other side of the cutting of Fig. 1.

Fig. 4 is a view of a roof made from "m alternating courses of both rights and lefts from Fig. 1. v

Fig. 5 is a view showing an" individual normally laid shin le effect made up by Jay ing staggered over ying courses of the strip shown and used in Fig. 5. I

Fig. 6 is a view showing the basic T shaped unit of m invention.

As shown in ig. 1, a piece of composition roofing material 1 is employed and a zig zag cut made lengthwise of it to form alternate extensions 2, 2, for the right half A, and 3, 3, for the left half B. The extensions and the alternate depressions be tween them for each half are of uric ual size although rectangular in shape, an it is readily to be observed that the extensions of one half form the depressions in the other.

One difiiculty in laying a roof from a tile of this character is that the long pieces of material cannot be used due to their bulk, and they must be'separated laterally into sections. To do this, a wide space ortile effect shingle is subject to the danger of exposing the line of jointure between two adjacent pieces in a single course, by the spacing of the shingle ike extensionsof the next course.

I avoid this danger, however, by cutting the halves of the long strip at different points considering'the original full width piece as a whole, always making a cut which will divide one of the half strips between the sides of a depression. Thus I make the staggered cuts and 5 in the full width strip 1, thereby bisecting the depression points of the rights and lefts. I may maize whatever length that is desired. every strip, however, b essentially a number bugs. as one of unseparated T-shaped units, as appears in Fig. (i.

It is not. necessary that but two extensions, or, as I will term them, shingle portions, to each unit be provided as shown in the drawor more units may be employed. The essential point is the-cross cutting of the continuous body of the strip on a line which intersects the depression, or space between shingle portion extensions.

In laying the root. it the cut is made halfway between shingle portions, the result will be that all pieces of each course are made up of equal T shaped units and the pieces may be laid with the extensions of one course abutting against the edges of the depressions of the preceding course. This will bring the lines of division of each course beneath the extensions of the succeeding course, and thereby protect the roof against leakage.

For this purpose. ordinarily a double cutter will be necessary that will make two cuts and 5 on different lines, as this will be easier than cutting the strips after they have been separated into halves, and prevent cutting either shingle through a projection. Double cutters have long been used in the art of paper making where sheets of paper are cut to different lengths, but this, I believe, is the first instance of its application to cutting strip shingles.

It will be remembered that the rights and lefts of the cut strip are not the same and in .view of this either of all letts, all rights, or alternate lefts and rights, may be laid in courses or further tiled or mosaic efi'ects gained by distributing the rights and lefts in laying the roof. The cross cuts 4 andv 5, must, however, be made between the sides of extensions so as to provide for the overlying feature hitherto pointed out, which is possible as a continuous process only with a double knife cutter.

Fig. 2 shows a roof made up of courses made up from the rights of Fig. 1, in which the extensions are of less size than the depressions. This gives a novel T-shaped effeet, which is very pleasing if laid with the extensions of one course laid to abut centrally on the base line of the wide depressions of the preceding course.

Fi 3 shows a roof made up of the lefts of Fig. 1. in which the extensions 2 of each course centrally overlie the narrower de- 1 pressions of the preceding course.

Fig. 4 shows a roof of a very novel paneled effect made up of alternate rights and lefts, with the extensions 3 of the lefts all in line vertically, and the extensions 2 of the rights all in line vertically.

Here again the cross cuts 4 are always located beneath an extending portion of the next course, and the effect given is of continuous staggered rows of wide and narrow panels running vertically of the roof, as distinguished from running laterally.

By the mention of these three forms of roof made 11 1 from the strips provided by my cutting, do not wish to limit myself to them alone, since there is a wide range of design which it is possible to obtain, bearing in mind that the depressions and extensions must be of relatively different size, and the cross cuts must be between extensions or preferably should exactly bisect the body portions between the side walls of the depressed portions.

I may further form my zig zag cut so that the shingle extensions and spaces vary for the individual sections in width and depth. There will be matching rights and lofts produced by such a cut but the shingle extensions will not be uniform for single courses.

A further arrangement of the type of strip shown as the right hand strip A in Fig. 1 may be made which will approximate the appearance of an individual standard shingle roof, as customarily laid.

As shown in Fig. 5, the courses may, in one form which I have employed, be made of strips having a five-inch body portion, four-inch extensions, said extensions being six inches wide, and lying 'eight' inches apart, and this figure is drawn approximately to scale on such a basis. The second course will be laid so that its extensions 3 lie between the extensions of the first course, in the particular dimensions selected.

The third course will be laid to bring its extensions into staggered relation with the first course, and so on. In a strip of the dimensions above mentioned, the cross out being as heretofore described, the exten' sions of the third course will abut on the line of divisions of the pieces making up the second course.

The strips having a five-inch body, as compared to a four-inch extension, the re sult will be that the first course underlies the connection joint of the pieces of the second course for a full five inches, whereas the exposure of the joint will extend only for four inches. Thus the joints of the pieces in the various courses will be very amlply protected.

laying of a root according to this last plan will result in a very strong and lasting structure, while the appearance will be more conservative than the other roofs which have been heretofore described.

In all types it can be observed that there is preferably a double thickness of material throughout, and in the last one described (Fig. 5), there is a triple thickness except for the spaces of one inch (see selected dimensions) between the extensions of the overlying courses, which will be double.

It is not desired because of the details above set forth to limit my claims that follow due to my failure in all or any instances to set forth alternative structure or methods of accomplishing them.

aving thus described my invention, what I claim as new and desire to secure by Letters Patent, is: g

1. That method of cutting out strip shingles for use on a roof which consists in cutting a median line through a piece of roofing material, said line leaving alternate extensions from the material at each side of the cut, and in cross cutting the material into sections or units by staggered lines interseating the spaces between extensions intermediate the Walls of said extensions.

2. A strip shingle roof com rising strip shingle units having body portions and bottom edge extensions simulating shingles said extensions being spaced apart to revea a substantial area of the sublying courses as distinguished from being mere slots, the extensions and spaces being of unequal width for each course, and the extensions and spaces for some courses width from the spaces and extensions of other courses, but with the total width of a space plus an extension being always equal for eachcourse.

3., A strip shinglin for roofs, comprising body portions having ottom edge extensions simulatingshingles, said extensions being spaced apart to expose portions of underlying strips of substantially shingle-like size, as distinguished from a crack or meeting line between adjacent surfaces, said body portions terminating in oppositely project ing ends free of extensions to form said spaces between similar ends of ad o1n1ng strips in a course.
