In carrying this into effect I provide, 35 Parent fTOm'a *wnsidelflfiml 0f the fOHOWiHg 684 along one transverse edgeof each flashing sheet, tailed description taken in connection with the an upwardly and outwardly inclinedstrip 5, which accompanying drawin wherein: strip terminates in arela-tively shorter horizontal F l isa plan View O a pb 't fim f-two fiashhook portion 6 adapted to overlay the upper sur- 40 m secti n showing y imp v d m n for face of an adjacent flashing sheet and in spaced 4O locking Ithe Sections together andalnhoring relation thereto.

An expansion joint is thus formed which will remain perfectly moisture-proof regardless of stresses and strains imparted to the sheets in use in a masonry structure and the overlapping edge portions of the sheets are held bonded to the mortar in which they are embedded by the overhanging anchor construc tion of the joint which extends up into the mortar.

On the upper face of the sheets'and between these interlocking elements of the joints I secure two or more rope-like wicks C to each section of flashing A-B so as to extend transversely of the sheets from edge to edge thereof as is clearly shown and described in the patent and application above referred to. In the'present invention however, I so construct the clips 9 which secure the wicks to the sheets as to provide means for anchoring the inte mediate portions of the sheets in the bonding mortar. V 7

As shown in Figs; 1, 2 and 3 these anchor clips 9 comprise relatively short sections of sheet metal, each of whichis bent into theform of oppositely and outwardly facing troughs iii, the vertical webs of which arespaced substantially the width of a wick C by the reversely bent integral portion I l of the upper, oppositely extending, flanges of the troughs. The lower flanges vof the troughed sides of the anchor clips 9 serve as means for securing the clips to the faces of the flashing sheets, as by soldering.

rows extending transversely the sheet and from the upper to the lower edges thereof. In the present invention I make use of the clips 3 as means. for also anchoring the under side of As indicated in Fig. 4 it has been found desirable to arrange the rows of clips ii intermediate the rows of clips 9 which are secured to the opposite face of the sheet. By this arrangement the bonding mortar enters the channeled sides of the

clips

9 and 9, when embedded therein, to interlock and key the mortar above the flashing sheet with the mortar below the sheet. In this waythe bond between the masonry above and below the flashing is maintained unbroken irrespective of stresses and strains set up in the sheets or masonry in use.

In Fig. i I have shown'a slightly diiferent form of anchor clip l2 and i2. These clips comprise relatively short sections of upwardly facing channeled sheet metal, the side flanges i3 and E3 of which are outwardly flared so as to extend at approximately 45 to the face of the sheet to which they are secured, as by soldering. As in the case of the anchor clips shown in Figs. 1, 2

and 3 these clips l2 and I2 may be used solely for keying the flashing to the mortar above and below the sheet or as a combined key or anchor this form, as in the preferred form shown in Figs. 1, 2 and 3, a metal strip I5 is soldered or otherwise secured to the upper face of a flashing section inwardly of-one transverse edge so as to extend at right angles to the sheet. The upper end portion E6 of the strip is preferably corrugated in a direction transversely of the sheet and bent over so as to extend slightly downwardly over the outer portion of the sheet to which it is attached and towards the transverse edge thereof. The adjacent transverse edge of a section of flashing to be secured in overlapping relation with the section so equipped, is preferably turned upwardly to provide a vertical flange H which is adapted to be looked under the substantially horizontal flange E6 of the vertical strip thereby firmly holding the adjacent edge portions of the two flashing sheets in interlocked, overlapping relationship.

In addition to providing an eflicient and economical expansion joint for two overlapping sections of flashing the lower inwardly flanged supporting edge of the vertical strip 55 may be provided with clip portions in the form of fingers is to be bent around a weep-hole forming wick C" laid transversely across the sheet adjacent the inner side of the strip 15.

While several illustrative embodiments of the invention have been described somewhat in detail, it is not intended to limit the scope of the invention thereby or otherwise than by the terms of the appended claims.

5. A flashing composed of at least two sheet metal sections the adjacent transverse side portions of which are adapted to be connected in face to face overlapping relationship, one of said sections having a laterally flanged, upstanding metal strip secured to its upper face inwardly of a transverse edge, and said other section having an upturned transverse edge portion adapted to hook under the laterally flanged strip of said first mentioned section.

6. A flashing composed of at least two transversely corrugated sheet metal sections the adjacent transverse edge portions of which are adapted to be connected in overlapping, registering relationship, one of said sections having an upstanding strip extending transverselyacross the sheet, the upper edge portion of which strip is laterally turned and transversely corrugated to provide a locking flange overlaying the corrugated side portion of the sheet, and said other section having an upturned transverse edge portion adapted to engage under the corrugated flanged strip of said first mentioned section, whereby to retain the corrugations of the over lapping portions of the sheets in nested relationship preventing displacement of the flashing sections in use.

7.
