This invention relates to roofing constructions and more particularly to a means for securing the overlapped edges of sheets of roofing material together.

An object of the invention is the provision of a roofing construction in which a plurality of sheets of roofing material have their adjacent ends overlapped for a restricted portion of the width and a narrow binding strip formed of roofing material folded upon itself to form a pair of superposed sec:

tions, tacks penetrating the innermost section and the overlapped ends of the sheets of roofing material and likewise a fixed portion of the roof for securing the overlapped ends of the sheets to the roof, the heads of the tacks being located between the superposed sections of the binding strip with cementitious mate'- rial located between the sections for'securing 539 the sections of the strip together, clips of any suitable material being employed when necessary for retaining the adjacent edges of the strips in contact with each other.

, This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless it is to be understood that the invention is not confined to the disclosure, 39 being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

Figure 7'is a fragmentary View in perspec- V tive of the form shown in Figure 6 showing the sections of the binding strip before they are secured together. 1

Referring more particularly to the drawing, 10 designates a sheathing of wood which is secured to the rafters of a roof before the sheets 11, 12 and 13 are applied. The sheets 11 and 12 have their adjacent edges 14: and 15, respectively, located in overlapped relation while sheets 11 and 18 have their adjacent edges 16 -and 17, respectively, located i IlaPPGd relation The binding strip, shown more particular ly in Fig. 2, and generally designated'by the numeral 20, is formed of a narrow strip of roofing material which is cut, as shown at 21, intermediate the longitudinal edges of the strip to form sections 22 and 23 which may be folded upon each other, as shown in Figure 1.

The section 22 is secured to either the overlapped. portion 1'? of the sheet 13 or to the overlappedportion 14 of the sheet 11 by 7 means 'ofa cement ordinarily used for'the purpose. Tacks 24 are driven through the section 22 and through the overlapped por tions 16 and 17 and into the sheathing 10 which *is preferably made i of wood... The

heads 25 of the tacks 24 are located between the sections 22 and23 and a binding cement 26 is placed between the sections 22 and 23 for aiding in securing the sections together and for retaining themin flat contact with each other. It will be seen by this construction that the heads of the tacks are made weatherproof since they are not exposed to the elements.

' U-shaped clips 27 have penetrating prongs 28 forced into the outer edges 29 of the sections 22. The projecting portion of the clip I is bent over the outer-edge 30 of the section 23 and over the outer face of said section. These clips are spaced along the edges of the-folded sections of the binding strip in fiat contact until the cement secures the sectionstogether.. y

23 ofeach binding strip will be formed into a unit while the lower section 22 will likewise be formed intoa unit by the gradual saturation-of the section-22and the overlapped portion 17 of the sheet 17. N V

The clips or U shaped members 27 are formed of soft metal and a're-of sufficient strength to maintain the edgesof the sections together until the cement will form a complete binding for the-sections. If the clips should become loosened for any reason, and released fromtheir position, after the 1 cement has securely connected the sections together, suchllooseness would have no effect whatever upon the eflicacy of the structure. The construction shown in Figures .4 and are substantially identical-with the con- Tstruction shown in Figs. lto 3,except that theclips 27 are not employed. in. this-case,

o In the construction shown in Figs.- 6 and 7 it will be seen that-two thin strips 35 and 36 are employed which are notbound bya relatively thin edge, as is shown in Figs. 1 In this instance, however; it is necessary to employ U-shaped clips 27 and 27* atthe opp-ositetedges ofthe strips for aiding in retaining the strips in flat contact with .each' otherwhile the cement binder has become suflicientlyset to retain the sections together. However, the tacks are employed in the same'n ann'er as that shown in Figs. lto 5, inclusive, and cement is employed for securing the strips 136=t0 the a overlapped portion of thesheet 13.1; Itwill also be notedthatthe portion 17 overlaps the portion 16 of the sheet-1 1 and the tacks in this case penetrate the sheathing 10 for two sections folded upon each other, tacks penetrating one of the sections andhaving their heads located between the sections, a cement binder between the superposed sections and between the'inner sections of the binding strip and the material forming the roof, and meansf'or securing the free edges of the sections together;
