June 24, 1930. A. E. F. MooNE ROOFING Filed Jan. 30,' 1928 Patented June 24, 1930 UNITED STATES PATENT OFFICE ALBERT E. F. MOONE, F CHICAGO, ILLINOIS, ASSIGNOR TO THE LEHON COMPANY, A

CORPORATION OF ILLINOIS ROOFING Application led January 30, 1928. Serial No. 250,404.

The invention relates to what is known in the trade as prepared roofing which usually consists of av foundation sheet of fibrous character commonly called felt, which sheet is impregnated with a waterproof composition and, in many instances, has applied to one side a coating of adhesive asphalt in which a layer of grit is embedded. This material is so flexible that very little force is required to bend it. Consequently, when laid upon a roof in overlapping courses the weather portions are likely to be lifted by the elements, permitting rain, snow, or the like, to enter between the courses and hence through the roof.

The principal object of this invention is to provide a fastening means and a method Yof laying that will permit the weather portions to be effectively and economicall secured. The preferred embodiment o the invention is illustrated in the 'accompanying7 drawings, in which fig. l isa plan view of a portion of a roo Fig. 2 isa section taken on the line 2f-2 of Fig. 1, and

Fig. 3 is a perspective view of a portion of a roong element equipped with fasteners of the preferred form. I

'However, this specific illustration and the correspondingly specific description are intended as illustrative only, for I realize that other forms may be readily devised without departing from the spirit of the invention and, therefore, the scope of the patent is to be found in the appended claims.

AThe supporting structure 10, shown best in Fig. 2, may be a roof or a wall, and upon this is a covering formed of a plurality of 40 overlapping courses of prepared roofing.

In this preferred form each ,strip or sheet includes a body portion 11 and a plurality.

of tabs 12 of semi-hexagonal form separated by complemental spaces 13. On the lower side of each tab there is secured a fastener generally indicated at 14. It is made of thin bendable sheet metal and comprises a base 15 anda tongue 16, the latter projecting beyond the'end of the tab. The base is cut on the lines 17 and 18 lto `form spurs, or

rivets, which may be inserted through the roofing and clinched on the opposite side.

In laying the roof the first course 19 is made of a plain sheet of prepared roofing nailed to the supporting structure at 20.

In laying the next course a strip or sheet like that illustrated in Fig. 3 is placed upside down beyond the eave and the tongues 16 inserted beneath the rst course 19. The strip is then revolved about the eave upwardly to take its proper position top side up with the tabs Hush with the eave. During this revolution the tongues 16 are bent somewhat short around the lower edge of the first course and the blow of a hammer on each fastener serves to embed the fastener in the roofing material and secure each tab firmly to the first course.

In the second course a similar operation is performed, the strip being laid upside down. with its tabs in the spaces between the tabs of the second course and the tongues 16 under the body portion of the second course. Next, it is revolved to take its proper position with the ends of the' tabs coinciding with the upper edges of the re- Cesses of the course below and its body por tion lying against the supporting structure where it is nailed. This operation is continued until the covering is completed, when a suitable comb, or ridge cap is applied.

By reason of the relatively short bends around the edges of the roofing in the course below each tab is securely fastened down wlithout the necessity of using nails, or the li e.

The fasteners are easily produced by automatic machinery and applied to the tabs at the roofing factory. They lie flat and lend themselves to convenient packing and shipping. ,Y

I claim as my invention: c'

1. Flexible prepared roolin comprising a body portion, `a plurality o tabs on one side of the body portion spaced by recesses of complementalshape and a thin bendable metal fastener secured to the underside of each tab, and projecting beyond the tab whereby such roofing is adapted to be laid in overlapping courses with the tabs of each course staggered with the tabs of the course below, each course being first placed u side down below the last course with t e fasteners inserted freely beneath the body of said last laid course and the respective tabs in the corresponding recesses and then rotated about the ends of the tabs to bend the fasteners short about the edge of the body portion of the last laid course and press the course being laid into overlapping relation with the course last laid.

2. A roofing strip comprising a body portion, spaced tabs thereon and a thin flat bendable metal fastener secured to the underside of each tab, and projecting beyond and in the plane of the bottom of the tab, said strips being adapted to be laid in overlapping courses with the tabs of each course staggered with the tabs of the next adjacent courses and the fasteners adapted to be freely inserted upwardly beneath the body portion of the course below and to be bent by the .strip about the lower edge of the body portion when the strip is rotated upwardly into overlapping relation with the course last laid.

3. A roofing strip comprising a body portion, and a plurality of thin bendable metal fasteners secured to the underside of the body along one edge thereof, and projecting beyond and in the plane of the bottom of the strip, said strips being adapted to be laid in overlapping courses with the fasteners adapted to be freely inserted upwardly beneath the body portion of the course below and to be bent by the strip about the lower edge of the body portion when the strip is rotated upwardly into overlapping relation with the course last laid.

In testimony whereof I aiix my signature.

ALBERT E. F. MOONE.
