SHINGLE Filed July 28, 1956 7 W EH50 I? 71222] f k Nowwq Patented Jan. 18, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to surface covering bodies of the nature of shingles.

The primary object of the present invention is to provide an improved shingle of the type which 5 is formed to represent several ordinary shingles,

in which a novel body design is produced which will efiect close engagement between two edges of the shingle body and the underlying supporting structure when the shingle is secured in place in the usual manner.

Another object of the invention is to provide an improved strip shingle having integral raised reinforcing ribs which in addition to strengthening the shingle body, serve as a guiding means for placing another strip in position and also serve to give the illusion of several shingles of ordinary width lying in side-by-side relation.

A still further object of the invention is to provide a strip shingle having integral raised ribs extending part-way across the strip whereby a flat portion is provided against which a superimposed shingle strip may be secured and having indicating or marking means lying between the ribs for assisting in locating a second or superimposed shingle strip in the proper position.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with so the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient fea- 5 tures of the invention as expressed in the appended claim.

In the drawing:

Figure 1 is a view in plan of a shingle strip constructed in accordance with the present invention showing the same applied over a starter strip.

Fig. 2 is a view in section taken transversely of two of the shingle strips and the starter strip and showing one of the shingle strips in the condition which it assumed before it is secured in place; and

Fig. 3 is a section on the line 3-3 of Fig. 1.

Referring now more particularly to the drawing, the numeral i generally designates a strip shingle constructed in accordance with the present invention, which shingle is preferably formed of a composition of asbestos and asphalt in such proportion as to produce a semi-flexible material hard enough to saw but sufliciently yieldable as to enable it to be easily out with heavy cutters such as tin snips. This shingle is of elongated rectangular outline, as illustrated, and is initially formed to have a slight transverse bow or curvature whereby when it is laid upon the sheathing of a roof to which it is tobe secured the central part will be raised up over the sheathing and a spring-like tension will be obtained to hold the top and bottom edges in firm contact with the sheathing and thus when the shingle is secured down by the nail 2, these contacting edges will be drawn more firmly into engagement with the sheathing than would be the case with an initially formed flat shingle, so as to establish a tight wind-proof and water-proof joint.

Each of the shingle strips is provided with a series oi transversely directed ribs 3 which extend from the outer or bottom edge of the shingle, as shown. Where the shingles are to be used upon a roof these ribs are preferably of a length equal to three eighths of the width of the shingle and when they are to be used as siding shingle's the length of the ribs is preferably approximately three sevenths of the width of the shingle. The top edge of the shingle is beveled as indicated at 4, through a distance approximating one-fourth of the width of the shingle. The bevel decreases toward the top edge from the full thickness of the shingle to a thickness of approximately three thirty-seconds of an inch or half the shingle thickness.

At the upper or inner ends of the ribs 3, nail depressions 5 are formed. These are in spaced relation. with the adjacent ends of the ribs so that when a single shingle is placed over the first the lower edge of the second shingle will completely cover the nails. As indicated the second shingles are placed with their lower edges in contact with the inner ends of the ribs of the underlying shingle so that the resultant efiect is that of a series of shingles of ordinary or standard width laid in the usual manner, that is, with the edges of one row in staggered relation with the edges of the underlying row or they may be in placing the shingles with the ribs 01' one strip of one shingle strip exactly on a center line between the ribs and theunderlying strip is assured.

The numeral 8 represents the usual starter strip which is placed along the edge 01 a roof to have the first row of shingles or shingle strips disposed thereover so that the said row will assume the proper angular relation with the roof sheathing to insure the following rows of shingles lying flat and form a water-proof joint.

From the foregoing it will be readiLv apparent that a shingle strip constructed in; accordance with the present invention may be easily handled and quickly applied because 01' the fact that the raised ribs or one already applied row of strips provide a guide means for the placing of the next row and-thus prevent the operator from getting the edge of the row out 01' alinement with the row of strips which have already been applied.

It will also be apparent that by providing shingle strips with the marking points I the strips can be readily placed so that the ribs 0! one row of strips will follow directly upon the center line between the ribs or the next row and thus the operator can work rapidly without taking the time to measure or otherwise carefully determine the position in which the strip should be placed.

1 claim:--

A shingle, comprising an elongated flat sheet oi material having an unbroken edge contour throughout and an undersurface which is flat and unbroken throughout, said strip being tapered from a line extending longitudinally and inset a substantial distance from one longitudinal edge to the adjacent edge, a plurality of ribs formed upon the top surface of and integral with the strip and extending from the other longitudinal edge transverselyof the strip and terminating short of said taper line, and said shingle being slightly bowed transversely, the concave side being the underside 0! the shingle whereby the shingle when flattened out by elements securing it to a root surface will have its tapered edge pressed firmly against the underlying surface.
