16 Claims.

This invention relates to shingles and more particularly to shingles of the interlocking flexible type.

One object of this invention is to provide a shingle which may be laid in interlocking relation with other like shingles to form a durable roof construction in which the exposed portions including the locking portions are securely fastened to the roof deck and thus secured against being lifted by the wind or otherwise displaced.

Another object of this invention-is to provide a shingle having a compound look, i. e., which may be interlocked with a plurality of locking portions of a similar shingle to form a strong lock between the shingles. In the preferred embodiment of the invention each locking portion of the shingle is associated with one corner on the portion of the element intended to be exposed to the weather and is defined by slots leading into the side and forward edges of the element defining the said corner.

Other objects and advantages will appear from the following detailed description.

The shingle of this invention comprises a body portion of general rectangular form bounded by a forward edge, a rear edge and transverse edges connecting the forward and rear edges. The shingle is provided in the neighborhood of a transverse edge with looking members lying within the outline of the shingle defined by the edges. Preferably the transverse edges of the shingle are provided with additional locking openings extending inwardly therefrom.

When the shingles are laid, the locking members in the neighborhood of one transverse edge of one shingle interlock with looking members of an underlying shingle to produce a compound look as will be described more in detail hereinafter.

The shingle may be provided with auxiliary locking members formed by cutting slits or slots in the locking members hereinabove described.

Figs. 12, l4, l6, 1'7, 18, 20, and 22 are plan views illustrating further modified shingles constructed in accordance with this invention; and

Figs. 13, 15, 19, 21, and 23 are fragmentary enlarged plan views illustrating how the shingles shown in Figs. 12, 14, 18, 20, and 22 respectively, may be locked together. I

Referring more particularly to the drawings, Fig. 2 illustrates a shingle l of generally rectangular form bounded by forward edge 2 intended to be exposed, rear edge '5 intended to be covered when the shingles are laid and

transverse edges

4 and 5 connecting the forward and rear edges of the shingle. 'The forward edge 2 of the shingle is provided with locking openings which may be in the form of slits constituted of inclined portions 6, 1, extending inwardly from the forward edge of the shingle and horizontal portions 8, 9, extending from the inner ends of inclined portions 6 and 1, respectively, towardthe transverse median line of the shingle. The shingle is provided with locking openings or notches Hi, I l, extending inwardly from the

transverse edges

4, 5 in substantially horizontal alignment with the horizontally extending portions 8, 9 of the locking slits. This construction, it will be observed, provides a pair of locking members l2, l3, in the neighborhood of the corner formed by the intersection of

edges

2 and 4 and another pair of similar shaped locking members I4, IS, in the neighborhood of the corner formed by the intersection of

edges

2 and 5.

The shingle may be provided with an aligning notch It on transverse edge 4 and an aligning tab H on the transverse edge 5 which tab may be complemental to notch H. Notches I6 and tabs l'l indicate the position in which the forward edges of the shingles of an overlapping course are to be laid with respect to the preceding coursein order to secure the proper amount of overlap between successive courses.

The shingle of Fig. 2 may be cut from a roofing sheet by a procedure which will be apparent from an inspection of Fig. 1. Notches I0 and I6 are formed by cut-outs along opposite longitudinal edges of the sheet. The notches l I and tabs ll are formed by cutting the sheet along a longitudinal broken line 20 and the resultant strips are separated into individual shingles by staggered transverse cuts 2|. The locking slits 6, l, 8, 9, may be formed during the cutting operation by appropriately disposed cutting members on the cutting cylinder or other cutting mechanism employed. It will be observed that the cutting of the shingles is accomplished without substantial waste of material, the only portion of the roofing sheet wasted being that cut out of the notches l0 and IS. A roofing sheet of a width corresponding to the combined width of any desired number of shingles may be employed. Such roofing sheet may advantageously be constituted of a felt base impregnated and coated with waterproofing material, for example asphalt, and having a layer of granular surfacing material partially embedded in the coating material.

The shingles may be laid in overlapping courses with each shingle interlocked with adjacent shingles of the same course as illustrated in Figs. 3 and 4. In laying the shingles, the locking members l4 and 15 of shingle A may, if desired, be deflected upwardly somewhat from the plane of the shingle and shingle B then placed in overlapping relation to shingle A with the locking members l2 and I3 underlying the locking members i 5 and M respectively of shingle A, and a portion l2 of the locking member [2 overlying a portion of the locking member M of shingle A. When the parts are properly positioned the notch Ill of shingle B engages the inner end of slit 9 of shingle A and the notch ll of shingle A engages the inner end of the locking opening 8 of shingle B. It will be observed that the shingles are reversible in the sense that they may be laid either from left to right or from right to left.

The resulting construction provides a durable roof, the exposed portion of each shingle of which is securely locked to each of two adjacent shingles by interlocking engagement between two locking members on each of the shingles, which locking members lie within the edges defining the body portion of the shingle. The roof is of pleasing design as appears from Fig. 4 which may be further variegated by laying shingles of some of the courses from right to left and others of the courses from left to right.

The shingle shown in Fig. 5 diifers from that of Fig. 2 chiefly in that the

locking openings

23, 24 extending from the forward edge 2 are of curved instead of angular configuration. These shingles may be laid as illustrated in Fig. 6 similarly to the shingles of Fig. 2, with the locking members 2'! and 28 of underlying shingle C overlying the

locking members

25 and 26 respectively of overlying shingle D. This construction provides a pleasing variation in a design of the roof. Fig. '7 illustrates a shingle which provides an even stronger interlock with contiguous shingles than the shingles of Figs. 2 and 6. The

locking openings

23 and 24 of the shingle of Fig. '7 may be similar to the corresponding openings of the shingle of Fig. 6. Additional locking openings 29, 30, extend inwardly from the forward edge of the shingle adjacent the points at which the

openings

23 and 24 enter said edge. The

openings

23, 24 and 29, 30, form pairs of locking members or

tongues

26 and 2?, 3i and 32, 33 and 34, one member of each pair being located in the neighborhood of a transverse edge of the shingle.

In laying the shingles (see Figs. 8 and 9) the

locking members

27 and 32 of shingle E may be deflected upwardly from the plane of the shingle and locking members 3! and 26 of overlapping shingle F inserted under locking members 2'! and 32, respectively. When the shingles are in interlocked position a substantial portion of the lock ing member 34 of shingle E will lie in the plane of and between locking members 3i and 26 of shingle F and a substantial portion of lockin member 33 of shingle F will lie between and in the plane of locking

members

21 and 32 of shingle E as clearly shown in Fig. 9. The applicator may then strike locking member 33 with a hammer or other tool to force this member and the underlying member downwardly so that the side edges of these members abut against the edges of locking

members

32 and 26, increasing the strength of the lock between contiguous shingles. The shingle illustrated in Fig. 10 differs from the shingle of Fig. 2 chiefly in that the locking members l2 and M are provided with

internal uts

36, 38 defining auxiliary locking members 36', 38, deflectable from the plane of members I2 and I4. When the shingles are interlocked as illustrated in Fig. 11, the auxiliary locking member 38 of shingle G is deflected outwardly from the plane of locking member l4 and overlies an edge of locking member 12 of shingle H. The auxiliary locking member 36' of shingle H is depressed downwardly from the plane of locking member l2 and underlies an edge of the locking member M of shingle G. The interengagement of the interlocking portions of adjacent shingles securely locks the shingles together and prevents relative linear movement of the shingles.

In Fig. 12 there is disclosed a shingle provided with

straight slots

40, 4| extending from the forward edge 2 in substantial parallelism with the

transverse edges

4 and 5 and defining

locking members

42, 43, 44 and 45. The shingles of Fig. 12 may be laid as illustrated in Fig. 13 with the

locking members

42, 44 of an overlying shingle extending beneath

locking members

45 and 43 respectively of an underlying shingle with the apex of the opening In looking with the top of slot 4! and the apex of the opening ll locking with the top of slot 46. The resultant interlock between the shingles is strong and efiective and the roof formed by laying the shingles presents a pleasing variation in design.

The shingle of Fig. 14 is provided with curved slits 4?, 48 extending from its forward edge and terminating in substantially vertical relatively short slits d9, 58. Angular slits constituted of. horizontal portions 5|, 52 and

vertical portions

53, 54 extend from the

transverse edges

4 and 5. Angular slits 5!, 53 define a locking member 53 and curved slit 4'l' defines a locking member 41'.

underlies the overlying shingle.

correspondingly on the opposite side of the shingle

angular slits

52, 54 define a locking member 54' and curved slit 48 defines a locking member 48'. These shingles may be laidin overlapping relation as illustrated in Fig. 15 with their exposed edges in alignment and with the locking members 53 and 41' of the overlying shingle underlying locking members 48' and 54' respectively of the underlying shingle.

The shingles of Figs. 16 and 17 may be employed where variations in design of the roof are desired. The shingle of Fig. 16 is provided with straight slits 51, 58 leading inwardly from its forward edge 2 and

curved slits

59, 60 extending inwardly from the

transverse edges

4 and 5 respectively. The shingle of Fig. 17 differs from that of Fig. 16 chiefly in that curved outwardly diverging slits 6|, 6| instead of straight slits extend inwardly from the forward edge of the shingle. These shingles may be locked together in the manner hereinabove described in connection with the shingles of Fig. 14. I

The shingle of Fig. 18 is provided with a slit 62 extending inwardly from the forward edge of the shingle, a curved slit 64 extending inwardly and downwardly from transverse edge 4 and another curved slit 66 extending inwardly and upwardly from transverse edge 5. The inner and open ends of slit 66 are in substantially horizontal alignment with the inner end of slit 64 and the inner end of slit 62 respectively. These slits define locking

members

61, 68 and 69. The shingles may be locked together as illustrated in Fig. 19 with the inner ends of

slits

64 and 66 of a pair of shingles in engagement and the locking member 69 of shingle L overlying locking member 88, extending through slit 62, and underlying locking member 61 of shingle M. This provides a double lock between the shingles in which a portion of a locking member of an underlying shingle adjacent the body of such shingle overlies a portion of an overlying shingle and another portion of the locking member of the underlying shingle remote from body portion of such shingle It will be noted hat by this construction the interlock between the shingles resists relative linear movement of the shingles in any direction.

The shingles of Figs. 20 and 21 are provided with curved slits H, 12 inwardly converging from the forward edge of the shingle and downwardly directed

curved slits

13, 14 extending from the transverse edges defining respectively locking projections H, l2, l3 and I4. The shingles may be interlocked as illustrated in Fig. 21 with the locking projections 13' and H of overlying shingle O underlying locking members 12 and M respectively of underlying shingle N.

In Fig. 22 there is illustrated a shingle having a straight slit 18 extending inwardly from the forward edge of the shingle in the neighborhood of. transverse edge 5, an angular slit extending inwardly from transverse edge 4 constituted of horizontal portion 80 and downwardly extending vertical portion 8! and a second angular slit extending inwardly from transverse edge 5 constituted of horizontal portion 82 and upwardly directed vertical portion 83. The closed inner ends of the portions 8| and 83 of the angular slits are in substantially horizontal alignment. This shingle may be interlocked as illustrated in Fig. 23 with the closed ends of the vertical portions 8| and '83 of the slits in engagement and with the locking projection 84 of underlying shingle X overlying the locking member 85 of overlying shingle Y. The end of the locking member 84 extends through slit 18 and underlies the locking member 86 of shingle Y. It will'be observed that the locking member 84 of the underlying shingle X comprises a portion adjacent the body portion of the shingle adapted to overlie aportion of overlying shingle Y and another portion remote from the body portion adapted to underlie another portion of the overlying shingle Y.

It will be noted that the shingle of this invention involves a body portion and a plurality of locking members lying substantially within the outline of the body portion, and associated with the corners of the element. The locking members are adapted to interlock with looking members of adjacent shingles to form a strong interlock between the shingles. These shingles may advantageously be laid in courses to provide a durable roof construction having the forward edges of each of the adjacent shingles in the same course locked together by a double lock which tends to prevent blowing or rippingup of the shingles by the wind.

While I have illustrated certain of my shingles equipped with looking openings constituted of slots and others with locking openings constituted of slits, it is to be understood that slots may be substituted for slits and vice versa.
