1,533,969 L. BUSHA STRIP SHINGLE Filed Feb. 11, 1924 INVENTOR a LEO/v BUSHA c a f By preferably of Patented Apr. 14, 1925.
LEON BUSHA, OF MINNEAPOLIS, MINNESOTA.
Applicatlon'flled February 11, 1924. Serial No. 692,157.
To all whom it may concern:
Be it known that I, LEON BUSHA, 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 Strip Shingles, of
which the following is a specification.
This invention relates to improvements in strip shingles for covering the roofs or walls of' buildings, said shingles being formed roofing felt or material of a similar nature, with a mineral coverin or surface usually formed of finely divided slate, stone, gravel, or similar material.
The present invention is an improvement on the strip shingle shown and described in Letters Patent of the United States issued to me August 14th, 1923, NO. 1,464,494.
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 sheet of material,
or aportion of a sheet, illustrating the manner in which the strip shingles may be cut therefrom; v
Figure 3 is a planview showing a preferred 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 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,
stone, gravel, 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 enerally rectangular form, but with the %ase of the butt widened by the diagonal or inclined lines a-b, and the lower end of the butt correspondingly narrowed bythe inclined or diagonal lines, c-d. Separating spaces, 3, 3, are thereby provided, each equal in outline or contour, and-area to the outline, contour and area of each of the butts 2. The shingle may be cut from a rectangular sheet'of sln le width by separating the sheet longitudina ly on the dotted lines 5--5, Figure2, and transversally on the dotted lines 6, 6,-and 8, 8. Q
If the sheet is of double width it will also be severed along the straight dotted line, 7, 7. From a sin le width sheet two strip shingles may be ormed by cutting in the manner described, and from a double width sheet four such shingles may be formed.
In starting the manufacture of the shingles from adouble strip, as indicated in Figure 2, there will'be at the end of the strip two small corners, e, e, which will be wasted, but there will be, no further waste until the HEISSUED opposite end of the sheet is reached. In
producing this'strip shingle the butts, 2, 2,
are located at the same distance from the ends of the body of the shingle, that is to say, the line af, that measures the distance from the right hand butt to the end of the shingle strip, isequal to the line a-g that measures the distance from the left hand butt to the left hand end of the shingle. The distance or cg is equal to onehalf' the distance hi between the butts the total vertical length of the butt will be substantially one-third the distance from the lower edge of the butt to the upper edge of the shingle so that in producing the shingle from a strip of material as outlined above, there will be no waste of material except at the corners of the ends of the strip. This produces an entirely symmetrical shingle and when the same is laid on a roof in overlapping relation as illustrated in Figure 3 of the drawings the roof will not only have the ends of the butts being correspondingly shaped with adjacent separating spaces and the distance from the point where the outer inclined line of one butt joins the body portion to the end of theshingle being equal to the distance from the point where the outer inclined line of the other butt joins the body portion to'the end of the shingle strip.
2. A shingle strip comprising a'body portion and a butt projecting from. one edge thereof, the butt eing connected with the body portion at the base by inclined oneither side of the butt, said butt also having vertical sideedges whereby when the shingles are located end to end there will be a separating space between proximate butts,
the end of the butt being correspondinglyshaped with adjacent separatin spaces and the distance from the point w ere the inolined line of each butt joins the body portion to one end of the shingles being equal tothe distance from the point where the 10 corresponding inclined line on the other side LEON B'USHA.
