ROOFING GLEAT.

(Originalappiication filed December 12, 1919, Serial No. 344,322. Divided and. this application filed March 7, 1921 To all whom it may concern:

Be it known that I, ALBERT C. Frsormn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented. certain new and useful Improvements in Roofing Cleats, of which the following is a specification.

lhis application is a division of application Serial No. 344,322, filed December 12th, 1919.

The object of the invention is to provide a cheap and efficient roofing cleat adapted for securing and weather-proofing or fireproofing the union between a roofing surface and the marginal portion of a roofing member superposed thereon, and particularly a com posite cleat formed in part by a weatherproofing material, for instance, fibrous sheet material, that is adapted to receive a cementing medium upon its faces through which it contacts with the roofing members that make up the joint to be proofed, and in part by more substantial material, for instance, sheet metal, overlying andqpreferably cemented to the fibrous material in position to sustain the latter against the securing nails, if

i used, and preferably also maintaining the shape, for instance, the offset between the difierent faces of the fibrous material; a feature of the preferred embodiment of the invention consisting in having the fibrous weatherproofing material continuous to an extent that adapts it to cover an extended length ofroofing'joint, and the metal reinforcing and sustaining portion subdivided into relatively short units spaced apart" lengthwise of and distributed over the continuous fibrous portion only in such numbers as maybe necessary to insure efliciency in the performance of the described functions.

In the accompanying drawing 7 Figure 1 is a perspective view of one embodiment of the invention.

Figure 2 is asimilar view of a modified form; and

Figure 3 is a section on the line 3*-3" of Figures 1 and'2.

seam between two overlapped roofing members. Adhesion between the sealing strip and the roofing members may extend over the surfaces of the laps alone or over the offset as well, and may be brought about by the application of roofing cement or other adhesive in situ to either the roofing members or the sealing strip; or, as is preferred, the adhesive quality may be incorporated in or upon the sealing strip at the place of proper and lower flanges C, C and a connect- 5% ing offset C The plates C may or may not be coextensive with the strips E transversely; they are not coextensive therewith longitudinally but merely extend over such longitudinal portions thereof as may be necessary to receive anchoring nails, maintain the form of the strip, and hold down the por- 110118 01 the roofing members concerned with the oint.

The reinforcing plates will preferably be constructedwith nailing bosses C providing inverted cups, as shown in Figure 3, in'which cement may accumulate to provide a packing around. @41

the intersecting nail.

The construction above described constrtutes a composite joint roofing and'securingcleat that is relatively cheap to produce and is very convenient and economical in its application, and particularly as a means of insuring proper application and distribution of nail-receiving members in roofing.

The composite cleats will generally be, shipped in such lengths as maybe handled without inconvenience and without injury to the cleats. When made with embodied adhesive, their adhering faces may be protect-- ed by placing two cleats back to back. If

when in this position reinforcing plates on one member bridge the spaces between rein-. forcing-plates on the other'member, a very rigid shipping package is insured.

I claim:

1. A composite roofing cleat comprising a" tilt / i strip offibrous material fashioned to conform to two relatively offset roof surfaces, and reinforcing plates of more substantial material secured to and spaced apart upon said strip.

2. A composite roofing cleat comprising a strip of. fibrous material fashioned to con-.

form to two relatively ofi'set roof surfaces, and reinforcing plates of more substantial material secured to and spaced apart upon said strip; said plates being fashioned to conform to said strip;

3. A composite roofing cleat comprising a strip of fibrous material composed oftwo;

laps lying in different planes with a' connectmg ofl'set web between them, and a series of plates of more substantial material conforming to the section of and secured to said strip and overlying both its laps.

lapped roofing members resenting surfaces offset by the thickness 0 a roofing member, and a composite cleat comprising a strip of fibrous material having laps overlying marginal portions of the respective roofing members adjacent their seam, together with a connectin web which overlies the edge of one of said members, and a series of reinforcing plates each comprising flanges ad herin to the respective laps of the strip and an ofisetting web overlyin the ofi'setting Web of the strip; said plates lieing secured to said strip in spaced relation to each other.

6. A composite roofing cleat comprising a strip of fibrous material, and plates conforming to the shape of said strip of fibrous material and cemented thereto; the opposite side of said fibrous strip carrying an adhesive or sticky mastic. 1

7. In combination, a fibrous strip of material and a series of roofing cleats arranged thereon in position to serve as securing means for overlapping sheets of roofing; said cleats having depending flanges adapting them to reach from the surface of an overlapped sheet to the surface of an underlapped sheet of roofin Signed at Chicago, Illinois, this 17th day of February, 1921.
