STRIP SHINGLE.

Continuation at application Serial No. 374,2!!8, filed April 15, 1920.

This application flied February 10, 1923. Serial No. 618,288.

To all whom it may concern:

Be it known that I, Leon Bosnia, a citizen of the United States, resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Stri Shingles, of which the following is a specification.

This invention relates to improvements in strip shingles, for coverin the roofs or walls of buildings, formed preferably of roofing felt, or material of a similar nature, with a mineral covering or surface usually formed of finely divided slate.

The object of my 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 of the sheet of material; that will, when laid, simulate the appearance of a tile or shingle roof, and that will provide at least two thicknesses of shingle at all rtions of the roof or wall, as fully as set orth in my application for Patent No. 374,208, filed A ril 15, 1920, in the name of Busha and Mc inney, of which this application is a continuation.

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 embodying my invention;

Figure 2 is a plan of a sheet of material, or a portion of a sheet, illustrating the manner in which the strip shingles may be cut therefrom without waste;

Figure 3 is a plan view showing a pre ferred manner of laying the shingles to form a roof or wall covering.

In the drawing, 1 represents the body portion of the strip shingle, which may be formed, in the usual way, of a foundation shingle sheet of wool felt with a coating or layer of pitch, asphalt, or the like, on one surface of the felt, and a layer of crushed slate or similar material pressed into the coating and held in place thereby.

I form, at one edge of the body, projecting extensions, or butts, 2, 2, here shown of rectangular form, separating spaces, 3, 3, being provided, each equal in outline, or contour, and area to the outline, contour and area of each of the butts 2, so that a rectangular sheet, such as shown in Figure 2,

may be divided, as indicated by the dotted lines 5, 5, thereby formin from a rectangular sheet, or a section tEereof, two of the strip shingles, without any waste whatever.

The edge of one of the butts coincides with one end of the body portion (at the left in Figures 1 and 3), and the total length of each shingle is doublethe total wi th of all the projecting butts. I have here shown each shingle provided with two butts, but a reater number may be employed if desiretf This arrangement provides each shingle with at least two butts and a corres ndin number of spaces.

may form the strip shingles by cutting the same across the sheet, the length of the shingle being, in such case, preferably equal to the width of the sheet of felt, such felt being usually formed in long sheets, that are rolled up and handled in the rolls. Sheets thirtytwo inches wide may be used, and, by cutting the shin les crosswise, a section of sheet 32 x 21 wi 1 form two strip shingles, with butts and recesses each 8 inches wide and 4 inches long and with a distance of 125 inches from the tip or end of the butt to the opposite edge of the body portion (on the line aa of Figure 1).

By cutting the shingles lengthwise of the sheet and making the butts 311- inches long, and the distance from the ends of the butts to the opposite edge of the shingle 10'; inches, (on said line a,a of Figure 1), four strip shingles can be cut from a sheet 36 inches wide, as illustrated in Figure 2; the sheet being separated into two parts on the line 6.

I refer to construct the shingles so that the distance from the tip of the butt to the other edge or top of the body shall be a distance equal to more than three times the length that the butt projects from the main body portion of the shingle.

By this arrangement the roof, or covering when laid, as indicated in Figure 3 of the drawings, has three thicknesses of material at the projecting butts, and two thicknesses of material elsewhere.

By this means I produce, without any waste, a very superior shingle that gives a maximum of three thicknesses of material in the roof or covering (atthe butts) and a minimum of two thicknesses of such material elsewhere, and in which the joints are all covered by the butts so that there are three thicknesses of material at each joint, an integral portion of a sheet being under and over each joint.

The length and width of the strip shingles, and the length and width of the butts, may be varied without departing from my invention. The contour of the butts may also be varied from the rectangular form shown, so long as these butts and the separating spaces are of the same size and contour, so that two shingles can be out without waste from a single, rectangular strip.

I do not limit myself, therefore, to any particular size or dimensions of the parts, nor to any particular material for forming the same.

I claim as my invention:

1. A strip shingle comprising a body portion having a plurality oi separated butts projecting from one edge thereof, the size and contour of each butt corresponding to the size and contour of the adjoining separating space and the end edges of the shingle being perpendicular to the longitudinal edges, whereby 'a pair of strip shingles may be cut from a rectangular sheet of material without waste, the edge of one butt coinciding with one end of the body portion, and the length of the body portion bein equal to twice the sum of the width of all t e projectin butts.

2. E strip shingle comprising a body portion having a plurality of separated butts projecting from one edge thereof, the size and contour of each butt corresponding to the size and contour of the adjoining separating space and the end edges of the shingle being perpendicular to the longitudinal edges whereby a pair of strip shingles may be cut from a rectangular sheet of material without waste, the edge of one butt coincidin with one end of the body portion, the length of the body portion being equal to twice the sum of the width of all the projectin butts and the distance from the end of eac butt to the o posite edge of the body portion being equa to more than three times the length of the projection of the butt from the body or'tlon.

3. A slab or strip s ingle, rectangular in form, with rectangular butts projectin from the lower side of said shingle, said butts being of equal width and separated by recta lar spaces of a width equal to that of each butt; said shingle being so proportioned that the distance from the ti or lower side of each bntt to the to 0 the shingle shall be a distance equal to more than three times the length ofdprojection of the said butt from the main bo y of the said shingle, substantially as described.

4. A strip shingle comprising a body portion having a plurality of separate rectangular butts projecting from one edge thereof, the distance from the end of each butt to the opposite edge of the body portion being equal to more than three times the length of the projection of the butt from the bod portion whereby when the shingles are lai with the butts slightly overlapped there will be three thicknesses of material at the projecting butts as shown and described.

In witness whereof, I have hereunto set my hand this 7th day of February, 1923.

LEON BUSHA.
