LEON BUSHA, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO WILLIAM EDWIN NELSON, OF MINNEAPOLIS, MINNESOTA.
Application led February 11, 1924. Serial No. 692,158.
This invention relates to improvements in strip shingles, for covering the roofs or walls of buildings, formed preferably of roofing felt, or material of similar nature, with a mineral covering or surface usually formed of finely divided stone, gravel, slate, or similar material.
The object of my present invention is to provide a strip shingle that can be cut from a rectangular sheet or strip of material without any waste whatever; that can be conveniently formed either lengthwise or crosswise the sheet of material; and that will, when laid, simulate the appearance of a thatched roof having a series of diagonally extending ridges with intervening hollows or valleys, thus producing a wavy effect.
The invention consists generally in the constructions and combinations hereinafter described and particularly pointed out in the claims.
In the accompanying drawings,
Figure 1 is a plan view of a single shingle embodying my invention;
Figure 2 is a plan of a portion of a sheet of material, illustrating by dotted lines the way in which the strip shingles of my pres ent invention may be cut therefrom without waste;
Figure 3 is a plan view showing a series of shingles laid one over another as the same are arranged in covering a roof or wall; v
Figure 4 is a perspective view of a portion of a building with the roof represented as covered by the shingles of my present invention, and valley effect that is given to the surface by the application of the shingles of the present invention thereto;
Figure 5 is a plan view of a single shingle showing a modification from the shingle shown in Figure 1.
In the drawing, l represents the body por-l tion of the strip shlngle, which may be formed in the usual way, of a foundation sheet of wool felt with a coating or layer of pitch, asphalt, or the like, on one surface a layer of nely divided slate, stone, gravel, or similar material pressed into the coating and held in place thereby. I
I preferably form each shingle strip with a straight upper edge 2, and with ends 3, 3,
illustrating the ridge-andat right angles to the edge 2; the lower edge 4 ofthe shingle strip being formed of a sinuous or wavy line,` the distance between approximate crests in the sinuous line being substantially equa The sinuous lines may be either curved, a`s shown in Figure l, or consist of a series of straight lilies extending in a sinuous direction as shown in Figure 5.
I may form the shingle strips from' a single sheet divided lengthwise by a sinuous line, a, a, as represented in Figure 2, or I may employ a double width sheet which will be divided by a straight line, Zi, as indicated in Figure 2, and the sheet will be cut into suitable lengths to form the shingle strips, as indicated, by the transverse lines, c, c, in Figure 2. It will be seen that the sinuous edges of the single strips are counterparts of one another so that a sheet, either of single or double width, may be cut into shingle strips without waste. The same result will be reached if the sinuous lines are made up of a series of as indicated in Figure 5.
I also prefer to provide a series of slots, 5, 6, 7, extending into the body of the shingle from the sinuous edge thereof, as shown in Figures 1 and 5. I may also forni, at the ends of the sheet, the notched recesses t5. two of which, when the ends of n shinghl strip are brought together, will form :i slot corresponding to one of the other slots in the shingle strip. The slots, 5, C, 7, and 8. preferably extend parallel to the ends. 2, il, and at right angles to the edge 2. These slots divide the lower-part of the shingle. strip into a series of butts, 9, 10, 11, and 12, when the shingle strip is made of such length as to make provision for this number of butts to a strip.
I do not limit myself, however, to the use of four butts for each shingle strip, as a ,greater or less number may be employed within the scope of my invention.
In laying the shingles on a roof or wall the upper edges 2 of the shingle strips are arranged in a horizontal osition or parallel to the upper and lower e ges of the roof or wall. These strips are also laid so that each strip overlaps the strip to the left one-half the distance between two of the slots inthe sinuous edge of the strip, as clearly shown in Figure 3 of the drawings.'
short straight lines,
`placed on another, withthe .and 4 of the drawings.
The result of this sinuous lower edge of the shingle strips, and the overlapping of the same, in the manner illustrated and described, is to produce the effect on the eye of the observer of an undulating or wavy roof surface, or a surface made up of a series of diagonally extending ridges with parallel diagonallyl extending valleys between said ridges, as clearly illustrated 4in Figures 3 and 4 of the drawings.
This efecthas not, so far as I am aware,
Abeen heretofore attained by flat shingle strips. 'It hasthe wavy or ridge-and-valley effect on the roof, which, as a matter of fact, is a perfectly at surface. This effect is very desirable and is attained without expense. The result is to produce an effective and readily Salable shingle at a minimum of expense.
I have illustrated the shingle strips as being cut lengthwise from a sheet of prepared material, but it is obvious that the same may be cut crosswise, and a sheet may be eniployed if preferred the width of which is equal only to the length of one of the shingle strips;
It will be noted that the slots 5, 6, 7 and 8, are not all of the saine length. The shortest slot 8 is the one formed by the halt slots at the ends.- The slot 6 at the center of. the shingle is the longest while the intermediate slots 5 and 7 are each longer than slot 8 and shorter than slot 6. The length of the slots is preferably such that when one shingle is slots in one midway between the slots in the other, the slots extend from the edge of the lower shingle to the edge of the overlying shingle, as indicated by the full and dotted lines in Figure 1. The endsof theA slots will in this instance form guides for positioning the shingles as they are laid in position on theroof.
l claim as my invention:
1^. A strip shingle'comprisin a body portion having a straight upper e ge and a sinuous lower edge to produce crests and valleys when a plurality of shingles are laid on a roof, the sinuous lower edge being so cut that when shingles are formed from a sheetof material, the sinuous projections of all such shingles will be the same, whereby shingles may be cut from a rectangular sheet of material without Waste, and when a series of said shingles are laid in overlapping relation with the crests of the sinuous edges slightly displaced, a waving or ridge and valley appearance will be given to the shingled surface.
2. A strip shingle coinprisinol a body portion having a straight upper e ge and a sinuous lower edge with a series of slots extending uneven distances from the sinuous edge towards and at right angles to the straight upper edge thereof and the sinuous edge of each shingle approximately coinciding with the upper edge of the slots ofthe shingle below.
3. A strip shingle comprising a body portion having a straight upper edge, a sinuous lower edge with a series of slots extending from the sinuous edge towards the center of the shingle and at right angles to its straight upper edge, the slots being of Such length that their ends coincide with the lower edge of a corresponding shingle, arranged in overlapping relation and projecting laterally over` the underlying -shingle a distance equal to one-half the distance between two of said slots. Y
4. A roof composed of overlapping shingles having their lower edges cut on approximately the same sinuous lines with the crests of the sinuations of an upper shingle slightly displaced from the vertical of the crests of the sinuations of the shingle below, this slight displacement extending continuously a distance through said shingle courses to produce a wavy appearance of the roof. In witness whereof, I have hereunto set my hand this 5th day of February 1924.
