THROGH WALL FLASHING Filed May 5, 1952 Patented Mayy 2, 1933 UNITED STATES PATEN'I joFFicE HENRY, E. VOEGELI, F WATERBURY, CONNECTICUT, ASSIGNOR TOTHE AMERICAN BRASS COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATIONOF CONNECTICUT 'rHRoUGH WALL FLASHING Application filed May 3, 1932. Serial No. 608,892.

This invention relates to new and useful improvements in wall flashings vand has particular relation to through wall flashings such as are used in brick or other masonry Walls to prevent water soaking th-rough and running down the inside of the wall.

An object of the invention is to provide a through wall flashing which may be manufactured at low cost and which when em-y tion with the accompanying drawing wherein the invention is shown. It is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the ap ended claims.

n the drawing:

Fig. 2 is a similar view and showing a flashing for a thicker wall; y

Fig. 3 is an enlarged detail sectional view along the line 3-3 of Fi 1;

Fig. 5 is a sectional view through a portion of,a wall and showing the improved flashing in'place therein, lthe flashing being sectioned as along the line 5-5 of Fig. 1;

Fig. 6 is a view similar to Fig. 5 but showing a slightly different flashing;

Fig. 7 is a plan view showing the flashing in relation to a wall and showing the interlocking joint between adjacent strips or sections of the flashing; and .j

Fig. 8 is a detail sectional viewon an enlarged scale, the view being taken along the line 8-8 of Fig. 7.

The improved flashing of the present invention is made up in sections or lengths and of sheet metal, preferabl copper. In the drawing the flashing of ig. 1 -is of a width for use in connection with 8 inch walls, while the flashing of'Fig. 2 is of a. somewhat greater Width and is adapted for use in 12 inch walls. However, the invention is the saine as applied to either flashing, the only difference in the flashings residing in'their width.

The flashing comprises a body or strip 10 which may be of a convenient length and the desired width and adjacent onelongitudinal edge the material of the body is offset upwardlyfrom the plane of the body as yindicated aty 9 to form a led e 11 and the extreme edge portion of sai longitudinal edge of the body is then inclined-upwardly providing av flange 12 forming a water stop. Extending in adirection generall transversely of the body and running rom the ledge 11 substantially to the opposite edge of the body area series of hollow zig-zag ribs. 13.

Ribs 13 are generally wedge or inverted V-shape in transverse cross section as clearly shown in Figs. 3, 5, 6 and 8 and these ribsmay be pressedA or rolled into the bod 10 and are open at their undersides provi ing zig-zag grooves at 14. A comparison of Figs of the latter figure are of a length greater than the length of the corresponding ribs of Fig. 1, this increase in length of the ribs equal to the increase inof that figure as com.

in Fig. 2 being width of the -bod pared with the Fig. 1.

Reference character 15 generally indiody of the flashing of 1 and 2 will show that the 'ribs 13 cates a portion of a brick wallA made up' of bricks 16 and horizontal and vertical layers 17 and 18 respectively of mortar. ObviouslIy, the mortar binds j the bricks together.

n the drawing, 19 indicates the inner sur# face of the wall, while 20 indicates 'the outer surfaceV thereof, and referring now particu- -larly to Fig. 5 it will be noted that thev imyply to each figure. edge of the flashing 10 of Figs. 6 and 7 exproved flashing 10 is embedded in a horizontal layer 17 of mortar with its outer edge 10a: substantially flush with the outer surface 20 of the wall and with its flange 12 disposed inwardly of the inner surface of the wall. Also, it will be noted that the mortar fills the zig-zag grooves 14 and completely encloses the zig-zag ribs 13 whereby the body 10 or flashing 10 is substantially completely embedded in the mortar.

Attention is also directed to the fact that the ledge 11 is as high or slightly higher in the wall than the tops of the ribs 13, and that the flange 12 extends above the ledge. Should water seep down through the mortar connecting the bricks or should water attempt to run down the inner surface 19 of the wall it will be caught by the flashing 10 or by the flange 12 of'said flashing and directed or diverted to the outer surface of the wall. There are no obstructions of any kind between the ribs 13, and the spaces between them f'orm channels, and it will therefore be apparent that water caught by the flange 12 or intercepted by the body of the flashing will be carried outwardly between the ribs.

Moreover, the sections of the wall above and below the flashing will be held against lateral movement in all directions since in order that one portion of the wall move laterally with respect to the other it will be necessary to shear off the mortar or cement entering the grooves 14 as well as that between the ribs 13 of the flashing. Should one portion of the wall attempt to move laterally with respect to another portion thereof in the direction of the length of the wall obviously the ribs 13 and the mortar in the grooves 14 will prevent such movement. Should the tendency for relative movement between sections of the wall be in either direction transversely of the wall it is obvious that the mortar received in the bends in the ribs together with the connection between the main body of the mortar and the mortar in the grooves 14 vwill prevent such movement.

Referring now particularly to Figs. 6 and 7 the arrangement of the flashin in the wall is the same as that already escribed and the reference characters used above ap- However, the outer tends beyond the outer surface 20 of` the wall and after the mortar has set, this extending edge portion 21 is bent downwardly as shown in Fig. 6 and may form a flashing over-lying the upperedge of an upstanding portion 22 of a roof flashing. In place of the relatively wide portion'21 the body or flashing 10 may extend but slightly beyond the outer surface of the wall so that when it is bent downwardly after the mortar sets it forms a relatively narrow drip edge.

In addition to forming a tie to prevent relatively lateral movement between the sections of the wall the ribs and grooves 13 and 14 also provide means whereby succeeding sections of the flashing used along the length of a wall may be interlocked; The manner of interlocking the adjacent ends of succeeding sections is illustrated in Figs. 7 and 8 and there it will be noted that the end of one section is disposed over the end portion of the next adjacent section and that the end groove in the lower side of the upper section receives the end rib of the lower section. This connection locks the sections together since it secures them against relative lateral movement in any direction owing to the fact that the grooves and ribs zig-zag. As the over-lapping end portions of Athe sections are embedded in the mortar or cement and as the weight of the upper portion of the wall will be on the flashing it will be apparent that the over-lapping end portions of succeeding sections of the flashing will be held against relative vertical movement.

From the foregoing description it will be apparent that I have provided a through wall flashing which may be manufactured at low cost since the grooves and ribs may be easily pressed or rolled into the sheet stock. Further, it will be apparent that in use my improved flashing will effectively tie together the upper and lower sections of a wall to prevent relative lateral movement between such sections. Also, succeeding sections of the flashing used along the length of a wall may be easily interlocked and without .the use of solder or the like since it is but necessary to dispose the end portion of one section over or under the end portion of the next adjacent section to have the end groove of one section receive the end zig-zag rib of the other section.
