INTERLOCKING SHINGLES.

Application led June 17, 1922. Serial No. 568,994.

To all 'wlw/m, i1'. may cof/warn.:

Be itjknown that I, llnnnnn'r ABRAHAM, a citizen of the United States, residing in the city, county, and State of New York, have invented a certain new and. useful Improvement in Interlocking Shingles, ot' which the following is a specification.

This invention relates to improvements in roofing shingles having projections on one edge, and particularly to such shingles made of prepared roofing material consisting of a foundation of felt or fibrous material, saturated and coated with bituminous compositions, and generally faced with crushed slate or other mineral matter.

The object of the invention is to provide shingles of such construction that when laid in overlap ing courses, portions of the projections ofpeach course will be received and caught in slits in the immediately underlying course, whereby to interlock the several courses with the butt ends of the projections held down firmly and without any loose portions.

The invention is susceptible of beingapplied to individual shingles or to strips comprising a plurality of shingles integrally connected, and it may bc embodied in a variety of different species several of which are described and specifically claimed in copending applications, this application being generic thereto. -It is my intention to claim broadly herein a construction comprising the common features of the several spec1es.

In the accompanying drawings,

Figure 1 is a plan view of a. shingle embodying one form of the invention,

Figure 2 is a plan view of several of such shingles laid in overlapping interlocked relation, and

Figures 3 and 4 show shingles embodying different species of the invention.

Upon referring to the drawings it will be noted that the several species of the invention shown, while diering in configuration, have certain characteristics in common. I shall proceed to describe these features of the construction.

Each shingle unit comprises a body 1 having a downward projection 2 at the middle portion of the lower edge, leaving shoulders 3 of equal lengths at both sides of the base of theprojection. The projection is irregular in shape, having indentationsV or re-entcring angles 4 in opposite parts of its sides. 'lhe length of the lower edge 5 of the projection measured horizontally, is equal to double the horizontal lengt-h of a shoulder 3.

l1n the body 1, and opening in the lower edge thereof at the points where the sides of the projection merge into said lower edge, are a pair of slits 6, one at each side of the projection. The lengt-h of each slit is equal to the distance .'12 from the apex of, an angle 4 to the end of the edge 5 at the same side of the projection. The slits are so positioned that. when a plurality of the shingles are laid side by side in a row the horizontal distance y (Fig. 2) between the innermost ends of the proximate slits 6 6 of laterally adjacent shingles will be e ual to the distance y between the apices or the re-entering angles 4-4 of a projection 2. It will be observed that in certain species of the invention the slits of each unit extend in diverging directions with respect to Aeach other, whlle in others, such as shown in Fig. 4, they are parallel. In each case, however, they are -so positioned that the above defined relationship applies. Obviously, without departing from the scope of this invention, the sides of the body l 'of the unit may be other than vertical. For that reason I have defined the location of the inner end of the slit with lrespect to the distance separating it from that of the companion slit of a laterally adjacent shingle rather than with reference to its distance from a side of the shingle itself.

It will be observed that the 1re-entering angles 4 form lateral extensions or wings at the lower end portion of the projection 2, which wings, when caught in the slits 6 of the next lower course, serve to lock down said end.

In laying, a plurality of shingles are placed side by side in a horizontal row to form a course. The shingles of the second course are then placed thereon in overlapped relation, with the ends 5 of the projections of the upper course registering upon the abutting shoulders 3-3 of adjacent shingles of the lower course, and with the lateral extensions or wings at the lower end portions of the projections, below the re-entering angles 4 thereof, inserted and cau ht in the proximate or companion slits o adjacent shingles ot the lower course, as shown in Fig. 2. The succeeding courses are similarly applied, it being understood that each course is nailed or otherwise fastened to the roof.

'llhe laid roofing will present various ornamental designs depending upon the particular configuration or' the projections of the shingles used. lln each instance, however, thev several courses will be interlocked with the lower ends of the projections held down rinly and without having any loose portions or corners What ll claim is:

l, A. prepared rooting shingle adapted with similar' shingles to be laid in overlapping inter-locked courses, comprising a body having a downward projection ot irregular A shape at substantially the middle or' its lower edge, the lower end portion of the projection having a wing at each side, the body having a'pair of slits opening in its lower edge at the points where the sides of the projection meet said edge, the proximate slits ot' adjacent shingles ol" any course being adapted to catch the wings of the projection of a shingle of the immediately overlying course, whereby to interlock the courses with the lower-.ends of the projections held downu 2. A. prepared rooting shingle adapted with similar shingles to be laid in overlapping' interlocked courses comprising a body having a downward projection at substantially the middle of itslower'edge, the projection having re-enterinp,- angles in opposite parts tog wings at the sides of the nordest lower end portion, the body having'a par of slits opening in its lower edge at tee points where the sides of the projection meet said edge, the length of each slit being equal to the distance from the apex of an angle to the lowermost corner at the same side oi? the projection, the proximate slits of adjacent shingles of any course being` adapted to catch the Wings of the projection of a shingle of the immediately overlyingr course, whereby to interlock the courses with the lower ends of the projections held down.

3. A prepared roofing shingle adapted with similar shingles lto be laid in overlapping interlocked courses, comprising a body having a downward projection at its lower edge and having shoulders of equal widths at both sides oi' the projection, thevprojection having rfc-entering angles in opposite parts forming wings at the sides of the lower end portion, the-width of the lower edge of the projection being double the widthoif a shoulder, the body having a pair of slits opening in its-lower edge at the points where lthe sides of the projection meet said edge,

the length of each slit being equal to the distance from the apex of an angle to the lowermost corner at the same side of the projection, the position of the slitsbeing such that when two shingles are laid side by side the distance between the innermost points of thel Y proximate slits or' the adjacent shingles will be equal to the width of the projection between the apices of the angles in its sides.
