STRIP SHINGLE.

- Application tiled March 22, 1922. Serial No. 545,144.

This invention relates to a strip-shingle made of prepared roofing, of the character having recesses in its lower edge which reccsses extend inwardly only apart of the distance that the strip is intended to be exposed when laid, and more particularly to an improvement in strips of the kind described in my Reissue Patent No. 15,280 of Feb. 7, 1922.

In that patentis shown and claimed a strip having spaced tabs on its upper edge, and having its lower edge divided at regular intervals into shingle-like portions by recesses leading into slots, the recesses and slots combined extending inwardly the distance that the strip is intended to be exposed when laid. The exposed portions of such strips, when laid in overlapping courses, simulate the appearance of separated individual shingles.

The present invention has for one of its objects the provision of a strip in which the shingle-like portions are partly defined by the recesses in the lower edge and partly delineated by markings on the body of the strip adjacent the recesses. This eliminates the necessity of cutting slots, with the consequent waste of material and other objec- .tions hereinafter pointed out, while retain- 'ing the advantages, both inappearance and structure, due to the formation of recesses in the lower edge.

In the. accompanying drawings illustrating the invention,

Figure 1 is a plan View of one form of strip in which the tabs and recesses are truncated,

Figure 2 is'a plan view of a portion of a roofing formed of the strip shown in Fig. 1, and,

Figure 3 is a plan view of a modified strip in which the tabs and recesses are pointed.

The strip 1 is made of prepared roofing consisting of felt or fibrous material, impregnated and coated with bituminous compositions, and preferably surfaced with particles of slate or other facing substance. Becesses 2 and tabs 3 are disposed at regular intervals along the lower and up er edges respectively, the recesses and ta s being mutually substantially similar in size and shape, and being preferably, though not necessarily, arranged in staggered order. The extreme depth of the recesses, measured transversely of the strip from an imaginary line coincident with its lower edge, is less than the distance that the strip is intended to be exposed when laid, being, preferably,

approximately one-half of that distance, as

seen in Figure 2.

Markings 4 extend transversely of the strip from the points of the recesses, which points may be eitherblunt or sharp, for the remainder of the distance that the strip is. intended to be exposed when laid. For example, if the strip is designedto be laid of the strip, is such as to give the exposed portion of the strip when laid the a pearance of separated individual shing es, as seen in the lower course of Figure 2. The markin s 4 at either end of the strip are prefera ly, each, one-half the width of the others so that when the strips are laid end to end in a row, the markings intervening all of the shingle-like portions of the course will be unifor The markings 4 are preferably black or colored to contrast with that of the strip itself, and may be formed either by removing the slate granules or facing to expose the black bituminous coating, or by applying paint, melted bituminous substance, or other suitable coating material over the mineral facing. In practice, the inner ends of the markings of a lower courseserve as gauges for laying an immediate upper course with the proper extent of the lower course exposed.

, From the foregoing description it will be seen. that my invention provides a strip having shingle-like portions which are defined partly by the edges of the recesses 2 and partly by markings 4 on the body of the -strip itself. This eliminates certain disadvantages of the type of strip wherein the shingle-like portions are formed by cutting away material to the entire depth of such portions. In a roof formed of strips of the latter type there is a posfibility that a strong wind might blow or bend back the shinglelike portions to the full extent of their exposure. With my improved strips, in which part of the shingle-like portions are formed on an intact body portion of the stripitself, that danger is avoided. According to this invention it is possible to form a i I practicable roof covering with strips of narrower over-all widths than has proven oomfmercially satisfactory with strips ofthe former type. a ile I have described and, illustrated my invention herein with particular reference to a preferred form of strip having spaced tabs .on its upper edge it is to be understood that. I do not limit myself in that respect.

What I claim is: As a new article of manufacture, a shingle strip of a length equal to the combined widths of a plurality of interspaced individual shingles, said strip being-composed of a fibrous base impregnated and coated w th bituminous compositions and faced with mineral particles, and having straight being broken at regular intervals by mutually similar shaped 'i'eceses whose sides converge inwardly from said edge toa depth equal to substantiall one-half the de th that the strip is iiiten ed to be exposed w en laid, the upper longitudinal edge having a plurality of evenly spaced tabs similar in shape to the recesses, the body of the strip being marked at intervals corresponding to the width of an individual shingle with narrow bandsofdark color, said bands extending upward from the inner ends of the recesses a distance not greater than the de th of said recesses, whereby, when a plura ity of such strips are laid in overlapped relation the efi'ect of the combined recesses and narrow dark bands simulates the appear ance of interspaced individual shingles.
