ing, crushing or flattening the S-` or `Zeshapexl Thepresent 'invention relates generically to flashing. More particularly, the'invention has particular relation to that type of wall ashing which is adapted to be embedded, in sheet form,
` in the' mortar between `the courses of Abrick of provided the wall and which is provided with deformations, such as ribs and projections, adapted to interlock and key the'mortar above the sheet of flashing to that therebeneath, as well as to prevent 'relative -movement between the mortar and the flashing in any direction.
A primary object of the invention is the provision of a novel form of ashing of the character above outlined which shall be capable of inexpensive manufacture but which shall nevertheless be highly eilicient in effecting its intended functions.
A further object of the invention is to provide a particular and novel relationship'between the several sets of deformations of the flashing rsheet whereby one set thereof shall act, in addition to carrying out its own'fintended peculiar function, to protect the other setv of deformations from injury, whereby the latter is positively enabled to perform the predetermined task assigned thereto.
To lthis end, the flashing according'to the present invention comprises essentially a lsuitable sheet or strip of metal, such as copper, which is with one set of deformations inthe form o a plurality of spaced transversely extending overhanging ribs which may be substantially Z- or YS-shaped in cross-section. Y
The peculiar conguration of these ribsprovides reentrant recesses in which mortar is adapted to be lodged when bedded ink a layer thereof so that the mortar above the flashing is in effect interlocked with that therebeneath. In this way, the bond between the mortar on each side of the flashing is not broken, as would be the case with ordinary flat sheet metal flashing. In addition, the ribs also prevent relative longitudinal vmovement between the mortar and flashing. Y
To prevent relative movement between the mortar and the flashing transversely of the latter, the strip is provided with a second setv of deformations in the form of a pluralityof series of projections Aextending upwardly from the'lbody of the metal intermediate the rst'set of deformations. These projections, which may be `of any suitable configuration, provide downwardlyopening recesses or pockets into which themortar is adapted to extend, whereby 'relative transverse movement of the flashing is prevented;l
When-the strip of flashing is embedded ln the layer of mortar onwhich .the relatively heavy coping block of the wall is placed, this block, finding inadequate support on the soft freshly'- laid'jmortar, bears downfuponthe sheet of ilashthe strip of` ashng is em-k ribs thereof,` eliminating the reentrant'recesses formed thereby, and consequently :destroying the interlocking and keying character of vthe flashing'.
To prevent such undesired set of deformationshe ribs-, the other set`v the projections-are disposed relatively closely adjacent to the ribs and are formed so 'that they .(or portions'thereof) extend upwardly 'to a point, appreciably beyond the their shape, these vprojections vare rstructurally much stronger than the ribs and can easily suplport considerable weight without being A`mashed or crushed. The coping block is therefor adequately supportedv by these projections, out of meshing of this one I tops ofthe ribs. Due to contact with the ribs, while the mortar hardens.
` Itis thus evident that the projections provided Vaccording to this invention exercise dual functions, rst,to prevent relative movement between the mortar and flashing and, secondlyfiao pro'- tect the transversely-extending ribs 4against crushing forces. l
On the accompanying sheet of drawing', wherein the invention is illustra-tively set forth,-
Flg. 1 isa top plan view of a portion-of the sheet lof flashing according lto one -embodiment'of the present invention; l
Fig'. 2 is a sectional 'view through the -coping block and top brick course of `a Ymasonry ivali 1 vembedded in the the vsectional view showing the flashing of Fig. layer of mortar therebetween,
of the hashing corresponding toline 2 2 Yof Fig. I
Fig.'3 is a sectional View taken on line 13-3 of Fig. 1.
Similar reference characters ref-er to corre'- sponding parts throughout the several figures-of drawing.
Referring now the drawing, lreference numeral Ill designates broadly a sheet of ashing fabricated from suitable sheet metal, preferably copper.` Inthe embodiment of the invention illustrated in Figs. 1 and 2, the sheetfof ashingis provided with a plurality .ofr` spaced ribs H extending transversely thereacross `and with a plurality ofsets of upwardly extending4 projections 13, I4 and|5, preferably arrangedas clearly shown in Fig-1. f
Transverse ribs lvl, as reference particularly to Fig. 2 of the drawing will show, are substantially f Z-shaped in cross section,
so that the flashing consists essentially (see Fig.13) of va plurality of relatively long parallel inclined areas (from which the projections I3`l4, I5 and the like may be displaced) connected by a pluralityof oppositely inclined relatively short areas.
The material adjacent the edges of the vlong areas and the short areas dene the Z. vvThe latter each forms a pair `of reentrant recesses 16,
as shown, adapted to'receive'morta ll-,fand
thereby keys the mortar above the flashing (Fig. 2) with that therebelovv. It is apparent that by reversing the relative inclination of the parts, the ribs II will be substantially S- insteadofZ-shaped in cross'section. In either case, a longitudinal section through the flashing along a line, such as 3 3 of Fig. l, will be substantially saw-tooth" shaped (see Fig. 3). The ribs II also prevent relative longitudinal movement between the flash- Y ing and the mortar.
Projections I3, I4 and I5 comprise areas or` portions of the metal flashing displaced therefrom and connected thereto by endlessv inclined Walls, as is clearly shown in Figs. 1 and`2. The latter figure of drawing further illustrates the vertical-:extent of the projections, and particularly projections I5, with respect to the top of the easily flattened Z-shaped ribs II. If the weight of the coping block I8 is too much .for the soft freshly-laid mortar, the ribs -II will nevertheless not be crushed by the block since the latter -willbe supported by the protruding projections, the structural form of which enables them adequatelyvto support the Weightof the coping b lockl. In addition to this protective function,.the projections I3, I4 and I5 also prevent relative horizontal movement in any direction of the flashing with respect to a cooperating layer of mortar 1(such as layer I'I, between coping block I8 and thecourse of bricksl9 of a brick wall). Y
Although a single embodiment of the present invention has beendisclosed in detail, numerous changes may bemade in the constructions Without departing from the spirit of the invention. The invention is therefore not intended to be limited by the foregoing specific disclosure no1` otherwise than by the terms of the appended claims.
