Patented Sept. 6, 1932 UNITED. `STATES was@ FRANCIS J. MOORE', OF MINNEAPOLIS, MINNESOTA ROOF FLASHING AND JACKET Application filed May 11,

My present invention relates to improver ments in roof flashingsI and jackets for vent pipes of the type disclosed and broadly claim-ed in my United States Letters Patent Roof flashing and` jacket for vent pipes #1,279,572 issued of date September 24, 1918, and wherein the flashing is bendable to change the inclination of the jacket in Vrespect to the flashing for roofs of different pitch.

In the commercial form of flashing and jacket gussets are formed in the vertical corners of a raised central portion in the flashing to which the jacket for a vent pipe is secured. These gussets are outwardly and transversely bulged to permit the same to be spread or contracted to change the pitch of the central portion of the flashing, and hence, the jacket. The lower ends of these gussets are open Ato rain or snow with a resulting leakage and `hence decay and they further permit an accumulation of dirt and al refuge for insects, bats and the like.

The object of the present invention is to close the lower ends 4of the gussets at the time of manufacture and in a manner that will permit free spreading or contracting of fthegus sets without affecting the -complete closing of the open ends thereof.

The invention further provides simple and '-30 highly efficient means forsecuring vthe jacket to the flashing and the application of al calking collar to the jacket to form a weather ftight joint between said j acket-and a vent pipelextended therethrough.

To the aboveendyvenerally stated, lthe in- Y vention consists of lthe novel devices and combinations of devices hereinafter -described and definedv in the claims.

In the accompanying drawings, which Vil- "10 lustrate the invention, like `characters findiycate like parts throughout theseveral views.

The numeral 8 indicates an inclined flashing for a pitch roof and has an upwardly pressed central portion 9 'arranged to leave the flashing 8 with a wide upper flange 10 Y and a narrow marginal front and side flange 11. Said wide flange 10 is adapted to beinserted under ythe shingles kor roof covering and nailed to the roof while the narrow flange 11 is adapted to rest on the roof .coveringand be nailed thereto to form a lweather tight 1.0 joint between'said covering and flashing 8.

\ The top of the raised central portionf9 has a much flatter pitch than the flashing 8'and said central portion, at its two vertical corners, is folded to form gussets 12. These gusi5 sets 12 are outwardly and transversely bulged `to substantially the form of inverted Vs, -whereby the sides Ithereof may .b e vspread or contracted to changethe inclination ,of the central portion 9 in -respectto the flashing 8.280 v Ashort upright cylindrical jacket -13 for a vent pipe, not show-mis secured-to the central portion .9 Aby having .its llower. end .portion telescoped into an annular opening 14 in said central vportion The .central portion 9 surrounding Athe .opening 14 `isoutwardly pressed fto form an annular I,groove 15 `between said `portion and the acket 13. `An external annular bead '.16 -pressed from the Tjacket 13 rests'on the cen-90 tral portion 9 and supports the jacket 13 therefrom. The jacket'13 below the opening 14, after beingrtelescoped therethrough, is outwardly pressed and' flared to lock the jacket 13 to the flashing 8. Solder 17 is#95 Aflowed in the groove 15 at the time of manufacture and forms a continuous ring `that 'frigidly connects the 'flashing 8 and jacket 13 and forms a .water see Fig.v 3.

'tight joint therebetween,

. Y q 10o A. calking collar 18 formed from a rela tively soft sheet of lead or other ductle metal forms` an extension of the jacket 13 at its upper end. The folding of the sheet of ductile metal is such as to form a three ply collar and the inner ply thereof entendsV laterally outward between the upper end of the jacket 13 and collar 1S and then laterally downward around said jacket. Said collar 1S is rigidly secured to the jacket 13 by two interlocked seams 19 one of which is'forme'd by folding the upper portion of the jacket` 13 outward upon itself and the other is'formed by folding the inner ply ofthe collar 18 inwardv upon itself. The collar 18 by its engagement with the upper end of the jacket 13 rigidly holds with the inner face of said collar substantially flush with the inner face of the jacket i' to form a tightjoint between the calking col- `lar 18. and vent pipe.,l said collar is-upset by pounding the same onto the jacket to form a tight joint therebetween.

To'close the open lower ends of the gussets 12 the lower endportions thereof are longitudinally slit at Vtheir crowns and the sides of each gusset 112 are bent laterally inward intoA overlapping engagement to form a pair of ears 20. The outer end portions of the ears 20 are rounded and folded the ears of the outer pair over the exterior of one of the sides of the gussets 12 and the ears of the inner pair over the interior of the other sides of said gussets. 'The ears 20 of each pair arevfree to slide, the one upon the other, during v the spreading or contracting of the gussets 12 to change the inclinationof the jacket 13 in respect to the flashing 8. In case of eXtreme expansion or contraction of thegussets 12 the roller outer ends of their ears 2O will engage the respective sides of the gussets 12 and slide thereon, thus causing the ears of each pair to slightly separate but without forming a direct passage therethrough.

I Y What I claim is:

Saol

3. An inclined flashing and a vent pipe acket secured thereto, said flashing having a vertical gusset that is outwardly and trans versely bulged to permit the gusset to be spread or contracted to change the inclination of the jacket, the gusset at its crown and lower end portion being longitudinally slit and the sides thereof being extended toform a pair of ears that are folded, the one upon thev other to close the open lower end of the gusset, said ears being free to slide, the one uponV the other, and permit the gusset to be spread or contracted. V

5. An inclined flashing having an outwardly extended central portion with a flatter pitch' than the flashing, a vent pipe jacket secured to said central portion, outwardly and transversely bulged gussets in the vertical corners of said central portion and adapted to be spread orcontracted to vchange the inclina` tion of said central portion, the gussets at their crowns and lower end portions being longitudinally slit andthe sides extended to form pairs of ears, the ears of each pair being folded, the one upon the other, to close the open lower ends of the gussets, the ears of each pair being'folded to slide, the one upon the other, and permit the gussets to be spread or contracted.
