SELF SEALING ASPHALT SHINGLES Filed June 17, 1957 MMM@ ATTO RNEYS.
United States Patent() SELF SEALING ASPHALT SHINGLES Walton V. Leibrook, Wyoming, and George Arthur Fasold, Mount Healthy, Ohio, assignors to The Philip Carey Manufacturing Company, Cincinnati, Ohio, a
corporation of Ohio Filed June 17, 1957, Ser. No. 665,958 2 Claims. (Cl. 50-103) In our companion application 'Seri-al No. 665 ,957 filed .lune 17, 1957 concurrently herewith and to the details and advantages of which reference is hereby made, We have explained the construction, shipping and packaging arrangements and the manner of application to a roof of our new high velocity wind resistant shingles. Such shingles have stripes of pressure sensitive thermoplastic adhesive applied to the upper weather surface of the shingles. The same principle of shingle manufacture applies to this application excepting that the adhesive stripe is applied in this case to the under surfaces of the strip shingles. Such an adaptation requires the application of the adhesive stripes on different lines with respect to the other dimensions of the shingles.
This application is a continuation-impart of our copending applications, Serial No. 634,708 filed January 17, 1957, now patent No. 2,863,405 and Serial No. 597,278 filed July 1l, 1956 now abandoned, which in turn is a continuation-impart of Serial No. 507,796 filed May 9, 1955 now abandoned.
In terms of dimensions instead of adhesive stripes being applied substantially two -to three inches above the line of the -top edges of the shingle tab cut-out slots, they must, when applied to the under surfaces of the shingles, be substantially two to three inches above the shingle butts in that portion of the shingles which are bisected by the cut'out slots.
The alignment of the adhesive stripes is not calculated particularly in terms of inches but in terms of that area of the underlying shingle structure which is bulged upwardly along the top edge of the undermost shingle or in that portion of the underlying course of shingles called the head lap. The head lap in double coverage assemblies is that amount that the top edges of the most underlying of the courses laps underneath the butt edges of the overlying courses.
Our copending application, Serial No. 557,563 explains in detail how stripes of adhesive may be applied continuously to the under surfaces of shingles. We may follow that method as shown or it may be modified in connection with requirements depending on the size and shape of the shingle elements involved. This application further illustrates methods of applying cover tapes.
In our copending application filed concurrently herewith we have disclosed several ways in which the use of adhesive repellent tapes disposed in nesting grooves on the under surfaces of shingles permits packing of the shingles in such a way that the shingles may be removed from the packing containers and are then ready for application in roof building.
ln this application wherein that modification is disclosed wherein stripes of adhesive are applied to the under surfaces of the shingle units or shingle elements, the formation of nesting grooves is still a desirable feature which permits convenient packaging of the shingles. But the positioning of the nesting grooves will be in the upper surfaces of the shingle units and in different relative positions on the shingles.
Accordingly in this application we have illustrated a modification of our invention in which the adhesive stripes are applied to the under surfaces of the shingles. The quality of the adhesive-pressure sensitive thermoplastic adhesive is otherwise the Same.
ICS
2 In the drawings: FIGURE 1 is a plan view of a strip shingle unit wherein van adhesive stripe is applied to the under surface of the element.
FIGURE 2 is a sectional view taken along the lines 2-2 inV FIGURE l.
FIGURE 3 is a perspective view of a roof showing the manner of application of the shingles.
FIGUR-E 4 is a detail sectional view along the lines 4-4 of FIGURE 3 with the elements expanded to more clearly explain the Vroof construction. K The strip shingle 1 illustrated for a seven inch tab exposure has dimensions of 16 in. height and a length of 42.85 in. The exposure area 1a of such a shingle is seven inches. The shingles are cut in the usual way from a web three times the width of the shingle for a 48 in. width machine. For a 72 in. wide machine with 8 in. shingle tab exposure areas the shingles would be cut from a web four times the width (i8 inches) of the shingle.
The shingles each consist of a saturated web or felt 2 coated on the lower surface with an asphalt coating 3` covered with `a layer of sand 3a or other finely divided mineral matter and with the upper surface coated with a layer of coating 4 surfaced with mineral granules 5.
The shingle is cut with tab defining slots 6 extending from the butt edge 7 of the shingle approximately seven inches. A stripe 8 of pressure sensitive heat plastic cement is distributed across the shingle 'along a line about two or three inches from the butt edge of each shingle unit.
In the application of the top surfacing material a scraper is so positioned as to remove the granule coating leaving a nesting groove 9 in the upper or exposure side of the shingle. Within the groove 9 we have shown a thin t-ape of adhesion resisting tape 10.
In packaging the shingles it is desirable to pack first one shingle right end up and the next shingle bottom edge up. Thus :the shingles will nest in an alternate end up arrangement and the tape 10 will prevent the asphalt cement stripe from sticking.
With this arrangement in laying the shingles it will be necessary to turn upside down as they come from the package every other shingle. Since the tape covered nesting groove in each shingle will be covered by the shingles in an overlapping course, it will be unnecessary to remove the tapes from the grooves. It will also be Within the scope of our invention to apply an adhesive repellent coating to the bottoms of the nesting grooves.
As an alternative arrangement, the tape 4may be used to cover the adhesive stripe but this will require the removal of the tapes before the shingles may be laid. This arrangement is not as satisfactory as applying the tape to the bottom of the groove.
As in our copending application, the dimension of two to three inches above the shingle butt is arbitrary. Actually the positioning of the stripe 8 will be in such position that it coincides with the upward bulge across the shingle caused by the underlying shingles in the course which has the head lap under the overlying course of shingles. It is this top edge of the head lap which causes the bulge or fulcrum which causes the adhesive to adhere so tightly that Wind resistance is overcome as in the other modifications disclosed in our companion application led concurrently herewith.
Having thus described our invention, what -we claim as new and desire to secure by Letters Patent is:
l. A high wind resistant roof covering comprising a plurality of similar flexible shingles laid in a double coverage arrangement, wherein the most underlying shnigle has a head lap of not less than two inches, so that in the head lap area, portions of three shingles are superposed Y 3 f upon each other, at wherein the top edge of said head lap forms an upwardly bulging fulcrum in the surface of the intermediateV shingle in said area, each of the similar shingles in said double coverage arrangement comprising a substantially rectangular body and having a substantially thick stripe of pressure sensitive adhesive of a tacky nature extending thereacross on its underside, in alignment with the upwardly bulging fulcrum formed by the top edge of the head lap of the rnost underlying shingle,
Ywhereby said stripe of adhesive is disposed between the uppermost and intermediate shingle in said head lap area.
2. A high wind resistant roof covering comprising a plurality of similar exible shingles laid in a double coveragearrangement, wherein the most underlying shingle has a head lap of not less than two inches, so that Y in the head lap area, portions of three shingles are supersubstantially coincides with the line of the top edges of the tab defining slots of an underlying shingle, each said shingle having a substantially thick stripe of pressure sensitive adhesive of a tacky nature extending thereacross on its underside, in alignment with the upwardly bulging fulcrum formed by the top edge of the head lap of the most underlying shingle, whereby said stripe of adhesive `is disposed between the uppermost and intermediate shingle in said head lap area.
