9 Claims.

This invention relates to a roofing element and more particularly to a reversible shingle of the interlocking type.

It is an object of my invention to provide means I integral with the shingle body whereby the lower exposed edge of the exposed lap portion may be securely locked down, regardless* of which edge of the shingle is exposed to the weather.

It is a further object of my invention to provide a shingle element capable of being reversed in laying yet which cooperates with adjacent shingles to provide a continuous connected lower edge' in each course of shingles whereby the edge portions are prevented from warping or being blown upwardly, the appearance and eiliciency ot the roof being consequently maintained against the elements.

Other objects and advantages of my invention will appear from the following detailed description in which j j Fig. 1 is a plan view of a preferred embodiment of my improved type of shingle;

Fig. 2 illustrates a method of cutting the shingle of Fig. l whereby the shingle may be cut from a single web of material without waste; and

Fig. 3 illustrates a fragment of roof laid with the shingles ofqmy invention.

InFig. 1 wherein a preferred embodiment of my invention is shown, reference numeral 21 indicates a main body. portion ofy'a shingle 20 of generalquadrilateral shape, the body of the, shingle being dened by longitudinal edges 22 and 23 and by sides24 and 25; It will be noted that the sides 24 and 25 are of substantially equal lengths, whereas longitudinal edge 23 is of som- I what greater length than longitudinal edge 22.

` projection 35, and a rec At the intersection of side 25 and edge 23, a projecting key portion 26 is provided, the lower side of which lies in alinement with and constitutes an extension of edge 23. The side edge of key 26 extends vertically on a line parallel to the side 25 to a point of intersection with an oblique upper edge 28, the two intersecting to form a pointed projection 27. 'I'he side 25 extends vertically from the line 28 to form with an oblique line 29, a second projection 31 which is similar in shape to the -projection 27. The line 29 runs inwardly toward the body portion 21 oi the shingle 20 to the line 32, which rises along a vertical plane to the longitudinal edge 22, lines 29 and 32 thus deflning a recess 46.

In a similar manner a key 33, projection 34, 47 are formed adjacent the side 24. i

The longitudinal side 23 is provided adjacent (Cl. 10S-7),

the key portions 26 and 33 with slits or slots 36 and 37, respectively. Slits 38and 39 in alinement with slits 36 and 37, respectively, are provided in the` upper edge 22 adjacent the respective projections 31 and 35. In Fig. 3 I have shown by way of illustration a section of a roof laid with my improved type' of shingle. The several courses of the shingles shown in the roof, i. e., courses I, II and III,- are shown as being laid by separate methods to 10 more fully describe the various methods of application to which the shingle of the present invention is adapted. l

In course I, which illustrates my preferred method of laying, the shingle units are laid l5 in adjacent overlapping relation with the longitudinal edges 22 and 23 placed in alinement one` with another and with the longitudinal edges 23 forming the lower exposed edge of the course. The projections 27 and 34 of one shingle are 20 locked in the slits 36 and 37 of the adjacent shingles to form a continuous lower edge which is securely locked in place. It will be noted that with respect to course I, either shingle may overlap the other so that the position of the transverse edge of the overlapping shingle varies, Ydepending upon which of a pair of adjacent shingles over.- laps the other. Hence,the shingles may be arrangedto avoid a monotonous design.

In course II, the method of laying comprises a I lacing of the key portions 26/and 33 and the projections 27 and 34 with the slits 36 and 37 of adjacent shingles, thep'rojectio'n 27 of one shinglea being locked in the slit 37 oi the adjacent shingle, and the projection 34 of the adjacent shingle be- 35 ing locked in the slit 36 of the rst shingle. This lacing of the joint between adjacent shingles provides' a secure and rigid connection between the adjacent shingles which serves to hold the lower edge of the course down against the roof, 40 thereby preventing warping and consequent leaking by the action of the elements.

In course III, I have shown still a further method by which my shingle may be laid. While the adjacent shingles are laid in adjacent overlapping relation as in courses I and II, the relatively short longitudinal edge 22 of one shingle is alined with the relatively longer longitudinal edge 23 of the adjacent shingle, the alternate relation being continued throughout the course. Considering y two shingles a and b in course III, shingle a. is

laid with the longitudinaledge 23 at the top and longitudinal edge 22 at the bottom, whereas shingle b is laid with the longitudinal edge 22 at the top and the longitudinal edge 23 at the bot- 555 tom. Shingle b is laid to overlap shingle a, the shingles being locked adjacent both the top and bottom edges. At the top joint the projection 34a is passed under projection 35D and locked in slit 39h. At the bottom joint, the projection 34b locks directly with the slit 39B. Thus the adjacent shingles of the course are. formed in a continuous strip, the individual members of which are joined at both the top and the bottom edges of the strip.

While I have shown a roof composed of courses laid by diierent methods, it is to be understood that this showing is purely by way of illustration and in practice a roof could be laid with only one method of laying employed throughout or a combination of methods as desired.

The shingles of my invention may be composed of various materials, but they are preferably constructed from a felt or brous base saturated with bituminous material to render it waterproof, coated with a bituminous or asphalt composition and subsequently surfaced with granular material. The brous base is preferably manufactured in the shape of a long, continuous web 41, shown in Fig. 2 having parallel sides as indicated.

In order that the shingle of my invention may be cut from the web 41 without waste, a method of cutting as shown in Fig. 2 is preferably followed. Four shingles are formed at one time transversely o f the web, although it is to be understood that any desired number may be formed, according to the relative dimensions of the web and of the shingles. The web 41 is cut transversely on lines 42, which are interrupted by the cuts forming truncated triangular sections 43 alternately positioned on opposite sides of the lines 42. It will be noted that the offset sections 43 at the ends of the web are of one-half the size of the interior sections 43. The web is slitted or slotted at 44 to form a series of transversely alined slits or slots at spaced intervals longitudinally of the web. Two series of slits 44 are provided to each transverse cut 42. The web is subsequently severed on longitudinal lines 45' to provide the shingle units desired. It will be noted that by the method of cutting disclosed, the slits 36, 37, 38 and 39 of the shingles 20 are formed in transverse alinement and in adjacent relation so that one cut serves to slit two shingle units. It will also be noted that the recesses 46 and 47 are complemental in size and shape to the projections 26,

27 and 33, 34 of adjacent shingles, thereby eliminating waste of material in cutting since the .ly with material ofone color and partly with material of a second color, thus producing a pleasing, vari-colored effect when laid.

From the above detailed description, it is obvious that my invention is possessed of many advantages.

A reversible shingle is provided which isv capable of being laid by a number of methods, a securely lapped lower edge being obtained by each method.

The structure of the shingle, including the projectionsat the opposite corners of one edge and the two pairs of slits in the opposite edges, one pair being located adjacent the projections, provide a shingle which may be laid either in normal adjacent relation or in alternate reversed relation to obtain any desired color effect or the like, while providing a locked lower edge which is securely held down and protected from warping and consequent action of the elements. Where the shingles are laid in alternate reversed relation, they are locked at both the upper and lower edges with a tight joint, thereby providing a strong and rigid unitary structure possessed of highly weather resistant properties.
