4 Claims. (Cl. 1087) This invention relates to composition roofs a slit 11 without removing any material from formed by laying individual shinges one by one the shingle. Also from the left hand vertical to have the last laid shingle interlock by a coredge at a slight distance up from the lower edge net with a shingle to the left thereof. It is a I cut a slit 12 horizontally therefrom and from 5 primary object of the invention to so form the the inner end of this slit 12 cut the shingle at 0 individual shingle that the lower exposed edge right ang es the eto d wa y toward the thereof is secured to the roof deck in such a lower edge to form the downturned slit 13. manner that it will not be lifted by wind pressure The length of the slit 13 may be somewhere in either directly under the lower horizontal edge the neighborhood from one-quarter to three- 10 or from an exposed vertical edge thereof. e gh s f an nc in e h W e the length 0 55 'An important object of the invention is to the slit 12 is substantially equal to the distance provide an individual shingle which may be cut from the slit 11 to the right hand vertical edge without waste and without the'necessity of havof the shingle 10. The length of the slit 11 is ing to cut out small pieces thereof which are apt substantially equal to the distance from the low- 15 to become embedded on the faces of the shingles er horizontal edge of the sh ngle 10 t0 the lower 70 in placing them in packages for shipment, and end ofthe slit 13. The actual dimensions may which precludes the necessityof having to form of course be varied as desired and the above inintricate dies and for matching one edge of the dicated dimensions are given merely to indicate shingle with a corresponding edge of another in the relationship between the various slits.
2c the roll of material from which they may be Referring now to Fig. 4, assuming thata left 75 cut. hand shingle A has been laid in place, a nail 14 A further important object of the invention is is driven throu h ub an i l y th c nter point to form a simple lock between adjacent shingles of the rectangle f m d n the lower right a in the same horizontal row whereby the mini- Corner Of th Shingle a bounded y the V t mum amount of any one shingle i required t and lower edges of the shingle, the slit 11 and an so be inserted under a shingle previously nailed mag na y line horlzontally drawn from the top down and also whereby a lock is formed between 0f the Slit 11 t0 the right hand g e dg h the two shingles whi h will prevent th lifting next shingle B is then laid down fiat on the roof of the lower corner of that shingle which corner d c and S pped upw ly and de-Wise to cause is not directly nailed to the deck, the corner 0 of the shingle A to be lifted sufficient- These and other objects and advantages will 5 to permit the Corner d to p ss th eunder with become apparent to those versed in the art by h left d d f the S ngle B coming Over the following description of the invention which on p of the Shingle A o as to have the inner is made in reference to the accompanying drawend of the Slit 12 approaching the up d of 35 ing i whi h the slit 11. Then the shingle B is pushed directly on Fi 1 g a tap plan view of a shingle embodyup to have the slit 13 of the shingle B move jng my i ti along the slit ll of the shingle A, which action Fig. 2, a diagrammatical representation of how Will bring the under 10We1' zont l edge of shingles embodying my invention may be cut the shingle B ll'ltO line With the lower edge Of the it from a strip of material:
Fig. 3, a plurality of shingles laid together to t Shingle B a d he Shingle A at the upper left form a roof covering and corner and on into the roof deck similar to that Fig 4, i i view of a gr up of hingles through the shingle A to the left. Also a nail 16 laid to form a roof covering but to have less lap may then b driven through the lower ht hand and more exposure.
Like characters of reference indicate like parts A Study of this corner k m d by the in the several views in the drawing. corners" of the shingles will show that the left It being an object of my invention to form a hand edge of each Shingle is always 1 top f shingle t t may be initially inexpensive and v the shingle to the left as its major lap and that 50 also that may be laid at the lowest possible 'cost, o ly that portion of the shingle t0 t right s 105 I form individual shingles 10 essentially recunder the Shingle t0 the left as is directly e ow tangular in shape and from the lower edge of the horizontal slit 12 so that there is only a very each. shingle spaced a short distance from the ma l amount of any Shingle that is quir d to right hand corner thereof I cut the shingle be pushed up under an adjacent shingle. Also 5 vertically upwardly from that lower edge to form attention is directed to the fact that by reason 119 corner of the shingle B.
of the short vertical slit 13 extending downwardly from the inner end of the slit 12, it is impossible to lift the lower edge E of any shingle above the upper end of the slit 11 such as might be the result of a high wind since the slit 13 prevents lateral movement of the left hand edge of the shingle and the right hand edge is nailed down to the deck. Similarly should a wind strike the roof from the left hand side, the shingles will not be lifted by reason of the fact that the shingles can not travel laterally again by reason of this same slit 13. To lift any shingle either from its left edge or its lower edge would mean that the 7 part of the shingle under the next shingle to the left would have to be pulled outwardly therefrom but this is impossible by reason of the engagement of the slit 13 at the upper end of the slit 11.
The shingles are laid in continuous horizontal rows and each row may be lapped to any amount desired over the next row below. The amount of lap as indicated in Fig. 4 shows the approximate maximum amount of exposure to the weather that may be obtained whereas in Fig. 3 the rows are so lapped as to give from two to three.
thicknesses of shingles over the deck. The small lap as indicated in Fig. 4, is employed where it is the intention to cover the roof with the fewest possible number of shingles and even with this small lap, there is no danger of the shingles lifting by their exposed edges. Of course with the greater lap as indicated in Fig. 3, a better roof is secured and the length of the vertical edges exposed is less.
While I have above indicated that the nail 14 is driven in the center of the rectangle bounded by the slit 1.1 to the left, it is of course entirely feasible to shift that point of nailing upwardly in the case where a joint or crack in the roof deck is encountered, it is always desirable to have the nail 14 pass through the shingle below.
I claim:
1. A roof covering comprising in combination, a plurality of horizontal rows of shingles made of flexible roofing material, each shingle being rectangular in shape and being provided with a vertical slit cut upwardly from the bottom edge adjacent the right vertical edge, the left hand edge of the shingle being provided with a slit cut horizontally from the edge into the shingle adjalcent the bottom edge and a slit extending downwardly a short distance from the inner end of the horizontal slit,,the adjacent shingles in each row being interlocked at the lower corners by having the shingles straddle each other about said slits to have that. part of the left edge of a shingle above its horizontal slit lap over ontop of the adjacent shingle and to have the remainder of that left edge inserted under the adjacent shingle through its vertical slit and the horizontal slit positioned above the upper end of the vertical slit which slit end is straddled by said downturned slit, and a fastening nail through each shingle to the right of said vertical slit and below the upper end thereof.
2. A roof covering comprising in combination, a plurality of rows of individual shingles made of flexible roofing material and having parallel vertical edges, one of which edges of each shingle is cut to have a slit extending by a major portion horizontally into the shingle at a short distance up from the bottom edge and by a minor portion sharply downwardly, the bottom edge of each shingle having a slit cut therefrom vertically upwards adjacent the other of the said vertical edges, said shingles being interlocked one with the next adjacent shingle by straddling the corners thereof through said slits to have that portion of one shingle between its horizontal slit and the bottom edge passed through the vertical slit and under the adjacent shingle with the portion of the first shingle above the horizontal slit lapped over on top of the adjacent shingle, the one shingle being positioned to have the horizontal slit above the upper end of the vertical slit in the other shingle by the length of the downturned slit, and a fastening nail through the corner of the adjacent shingle between the vertical slit and the adjacent lapped over vertical edge thereof.
3. As a new article of manufacture, a rectangular shingle made of flexible roofing material having a slit cut from its bottom edge upwardly spaceda short distance from a vertical edge and having a slit cut from the other vertical edge distance as that of the upper end of the other slit from the bottom edge of the shingle.
4. A roof comprising courses of overlapping shingles, each shingle having a pair of integral flaps formed at the opposite lower corners thereof by cuts in said blanks, one of said cuts extending inwardly from one side of said blank and the other cut extending inwardly from the lower edge adjacent the bpposite side of said blank, the bottom-cut flap of one shingle being adapted to be nailed to a roof, and the side-cut portion of the adjacent shingle being adapted to overlap the nailed side of said first-named shingle with its side-cut flap underlaying said first-named shingle inwardly of said nailed flap whereby a double overlapping interlock which seals said nailed flap against seepage of water thereto is provided.
