w. J. DOYLE ROOF FLASHING Filed Sept. 22, 1924 eljaxg ATTORNEY WITNESS:

Aug. 3, 152%.

pairs stares earner-- ROOF FLAS/HING.

Application filed September 1,92%. Serial No. 739,144..

This invention relates to improvements in roof flashings especially designed for use around stand pipes and the like, an object being to provide means whereby a flashing collar may be tightly and securely fastened around a pipe in a manner to prevent see age of water down the pipe into the collar.

Another object of the invention is the provision of a pipe flashing having an expansible fian e at one edge thereof to provide means w iereby the flashing may be properly positioned by a single workman within a relatively short time and with a minimum amount of labor.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a fragmentary sectional View showing a portion of a roof with the invention applied, the section being substantially on the line 1-1 of Figure 2.

Figure 2 is a top plan View of the invention per se, a pipe being shown in position.

Figure 3 is a fragmentary elevation showing the upper portion of the collar and the formation of the ears.

Figure 4 is an enlarged fragmentary elevation showing the upper portion of the collar in position around a pipe, parts being broken away.

Referring to the drawings in detailwherein like characters of reference denote corresponding parts, the reference character 10 indicates a portion of a pitch roof for which the invention is especially adapted while 11 indicates a stand pipe.

The invention includes a collar 12 which is substantially cone-shaped and which has its upper restricted end slitted as shown at 13 and the portions of the collar upon opposite sides of the slit bent outward along inclined lines indicated at 14 to provide ears 15. Bent over the upper edge of the collar 12 is a packing strip 16 which is preferably formed of soft lead and extends downward inside of the collar for an appreciable disof the collar and consequently the packing strip 16 may .be drawn into tight engagement around the pipe 11. As the lead packingstrip extends to the edges of the slit 13 and the bolt 18 passes through the adjacent ends ofthis strip, the strip is securely held in place and is squeezed tightly together so that a perfect joint between the upper edge of the collar and the pipe is provided.

The lower end of the collar 12 has extending therefrom a flange 19 which may be formed in any suitable manner. For example, a sheet metal plate having a central opening for the passage of the pipe 11 may be provided and the lower edge of the collar 12 may be bent outwardly and soldered or otherwise secured to this plate as indicated One end ofthis flange 19 has extending therefrom oppositely disposed guide flanges 21 which slidingly receive the opposite edges of an extension plate or flange 22 which is. adapted. to be positioned beneath the adjacent edge of shingles 28.

Ordinarily, a flashing collar having a solid flange requires the workman to ascend to the roof after the hole has been out so that the flange may be pushed up under the shingles. He must then go back inside the building to shove the pipe up through the roof flange, after which he must return to the roof to fasten the flange and caulk the collar around the pipe. With the-present invention the hole is cut in the roof and the pipe inserted. The workman then ascends to the roof and drops the flange over the pipe after which the extension 22 may be pushed upward beneath the shingles 23. The operation of installing the flashing is thus materially simplified.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is c 1. A roof flashing for pipes and the like comprising a substantially cone-shaped collar slitted longitudinally at its restricted end, ears bent outwardly along inclined lines upon opposite sides of the slit, a packing extending around the collar over the restricted edge for engagement around the pipe with. one edge extending downward inside the collar beyond the other edge, means extending through the ears and packing whereby the latter maybe drawn tightly around the pipe and the adjacent edge of the packing squeezed together and a flange extending around the base of the collar.

2. A roof flashing for pipes and the like comprising a substantially cone-shaped collar, means whereby the upper restricted end of the collar may be secured around a pipe, a flange extending from the base of the collar, oppositely disposed guide flanges extending from one endand an extension plate having its opposite edges Slidable in said guides and movable relative to the flange.

In testimony whereof I afiix my signature.

WILLIAM J. DOYLE.
