FLASHING Filed Sept. 6, 1932 #im n n M7 6 MTX x x V7/aries' 500742129 Patented ug'. 21, 1934 4 UNITED STATES, PATENT. OFFICE I Y LAsHIG Charles A.V Earlvey, ljorchester, Mass. y Application september s, i932, serial No. `sarees 4 claims. (oigvz-izvii This invention relates to improvements in sheet metal flashing and has for its object to provide' a strip of flashing that may be inserted in the binding material that is employed between the vadjacent courses of masonry of a wall for the purpose of arresting the downward seepage of water through said wall, and then diverting vsaid water to the exterior of the Wall.

Another object of the invention isto form a" strip of flashing in such a manner that when it plane.

extending rows of intersecting corrugationsbetween which are also provided both longitudinally and transversely extending intercommunieating grooves, all of which are so arranged that when the flashing is inserted in the binding projections or corrugations in a manner to bridge the Aintervening grooves, making it impossible for the binding material to enter these vgrooves and the wall.

The invention consists in an improved forni of" sheet metal flashing and cap therefor ,as set' forth in the following specification and particularly as pointed out in the claims thereof.

Referring to the drawing:

Fig. 1 represents a plan View of a portion of a strip of flashing embodying my invention.

Fig. 2 is a detail sectional view of a portion of a wall illustrating the adjacent end portions of two strips of flashing interlocked together and embedded in the binding material that is employed between adjacent courses of masonry, said section being taken through one of the strips as indicated by the line 22, Fig. 1, looking in the direction of the arrows on said line.

Fig. 3 is a detail sectional view illustrating adjacent courses of masonry oi a wall with the flashing embedded in the binding material therebetween, the section extending through a strip of flashing as indicated by the line 33, Fig. 1, looking in the direction of the arrows on said line.

' Fig. 4 is a plan view of a portion of a strip of Another objectof the invention is to provide the flashing with longitudinally and transversely" flashing illustrating lcorrugations or projectionsl of a modified type formed'thereon.

Fig. 5 is a detail sectional' view through a'wall and through the` flashing as indicated by the line 5 5 of Fig. 4, looking in the direction of the arrows onvsaid' line. Fig. 6v `is a detail sectional view through a wall andthrough the flashing as indicated by the line 6 7-6 of Fig. 4, looking in the direction of they arrows on said line.

Fig. l'is a'detail sectional view illustrating another lmodified Vembodiment of the invention.

` Like numerals refer to like parts throughout the several views of the drawing.

41n the drawing, referring particularly to Figs. 1;-2"and-3, 10 represents a strip of flashing preferably constructed .of sheet metal. Formed at. regular intervals upon the strip offiashing 10 are rows of b othlongitudinally and transversely extending corrugations 11, between which are longitudinally extending grooves 12 and transversely extending grooves 13, all of which communicate with each other. The rows of corrugations j 11 are'formed as pyramidal projections 14 which are pressed upwardlyfrom the sheet of flashing 10, thereby forming pyramidal recesses 15Vupon the underside @of 'the flashing. The4 projections 14 'and recesses'15` are so formed that when the e strip` 0f flashing 1 0 is inserted in the binding mathereby providing a drain above the fl a'shing through the binding material to' the exterior of 'e will enter the grooves -12 andV 13 that are providedV uponjftheupper 'surface of the flashing bindingI material4v together 'and prevent the flashing from moving in a horizontal plane in the binding material and between the courses of masonry. It will be noted that the grooves V12 and 13 and recesses 15 are all formed in such a manner that the binding material 16 will easily enter all parts of said grooves and recesses without it being necessary to apply excessive pressure to either the binding material or the flashing Positioned at intervals upon the upper surface of the flashing 10 and extending transversely thereacross is a cap 18, which rests upon the tops of two adjacent transversely extending rows of projections 14 and bridges the intervening groove 12, leaving a space therebeneath from which the binding material 16 will be excluded, thereby forming a drain which will extend across the strip of flashing. The opposite longitudinal edge portions 19 of the cap 18 are bent downwardly and engage the sides of the projections 14 in a manand recesses 15 upon thelunder surfaceof ythe flashing and act to bond the strip of hashing and '90* extending caps may be provided as may -be'desired, and the drains provided therebeneath will communicate with the transversely extending drains.

In Figs. 4, 5 and 6 I have illustrated a modified embodiment of my invention in which a strip of flashing 21 is provided with rows 'of"longitudinally and transversely extending corrugations 22 formed approximately as pyramidal projections 23, between which are located longitudinally and transversely extending grooves or depressions 24 which communicate one with another.`

In this form ofl flashing the obverse and re-, lverse surfaces of the flashing are identical, and.

binding material 25 located between courses of masonry of a wall26 will enter the-grooves or depressions 24 and eifectivelyjprevent'the flashing. from moving ina horizontal'pla'ne between the I courses of masonry. In this' form of vflashingit will be noted that the projections,anddepressions are all so formed that' the bindingmaterial will easily enter all parts of the' 'depressionswithout it being necessary to apply'excessivepressure to jeither the binding material or, the ashing.

Caps, similar to the caps 18'and'20 previously described, may be used if it is so desired in con-Vv nection with this form of flashing, but it is evi-` dent that it will `be impossible to entirely drain uniform depth. p

In Fig. 7 I have illustrated still'another-modied embodiment of the invention, .in which 'a .l5-strip of flashing 27 is providedwith `rows of both longitudinally and transversely.extending oorrugations 28 which 'are formed as segmental spherical projections 29vwhich are pressed upwardly from the sheet of flashing, .thereby form- -ting recesses 30- upon the under side'of the ash- "ing. The projections 29 are spaced at exactly-the same manner as are the projections 1,4 previously described and have longitudinally `and transversely extending intercommunicating grooves 5551-31 provided therebetween.

A cap 32 similar to the cap 18 previously derthe upper surface of the flashing, for the reason Hthat the grooves or depressions 2 4 are not ofscribed rests upon the tops of two adjacent transversely extending rows of projections 29 and bridges the intervening groove 31, leaving a space therebeneath from which binding material 33 of a wall 34 will be excluded, thereby forming a 80 drain which will extend across the strip of flashing. Another cap 35, similar to the cap 20 previously described, is also provided, said cap 35 being positioned upon the flashing in exactly the same mannerand for the same purpose as is the cap 20.

The flashing illustrated in Fig. '7 is used in exactly the same manner as is the flashing illustrated in Figs. 1 to 3 inclusive, but differs therefrom solely in the fact that the projections are formed as segments of spheres instead of being pyramidal.

I claim:

1. A sheet metal flashing for masonry structures 'comprising a, metal plate having longitudinally and transversely extending rows of intersecting corrugations and intervening intercommunicating grooves adapted to serve as a key for mortar, and a cap embodying therein marginal positioning meanssaid cap resting upon certain of said corrugations and bridging the intervening grooves.

2. A sheet metal flashing for masonry structures comprising a sheet of metal of the width to extend substantially' through the wall of a structure, said flashing being provided with hollow-.pyramidal projections and intercommunieating arcuate grooves whereby moisture of infiltration from said wall, collecting upon the upper surface of said fiashing, may be deflected 13m and drained to anvouter surface oi said wall.

3l A sheet metal flashing for masonry structures comprising a sheet of metal of the width to extend substantially through the wall of a structure, said fiashing being provided with inter- 115 communicating grooves whereby moisture of infiltration fromsaid wall, collecting upon the upper surface of said flashing may be deflected and drained to an outer surface of said wall, and a plurality of intersecting caps resting upon said flashing above certain of said grooves and forming covered vintercommunicating drains thereof.

4. A sheet metal flashing for masonry structures comprising a metal plate having raised hollowprojections on the surface thereof and a metal .capresting upon-certain of said projections and spanning the area of plate therebetween, whereby a hollow space is provided beneath said cap to drain moisture of infiltration to the exy y terior of said structure.v y 1,3@
