' MEYER, 0F MILWAUKEE, WISCONSIN FLASHING Application filed February 14, 1930. Serial No. 428,344.

This invention pertains to flashings, and has primarily for its object to overcome various objections found in conventional types of flashings, and to otherwise improve such structures, whereby saving in material is effected and installation is facilitated.

In fiashings, as heretofore constructed, considerable difliculty has been encountered in joint between the flashing and wall to effectively prevent the ingress of water and moisture; These objections result from the fact that previous flashings employ restricted grooves for reception of the counterflashing, which grooves are positioned within the wall or partition and, therefore, readily obstruct ed by the masonry material, concrete, or cement employed, or by accidental bending or denting in the handling and installation of the flashing, or by pressure exerted upon the flashing from superimposed masonry.

Also, considerable difiiculty has been encountered in positioning the spliced plates usually employed, due to the fact that the flashing structures require spliced plates to be inserted in the rear and positioned upon the underside of the flashing, after the flashing has been set upon the soft mortar or cement.

Furthermore, previous flashings have required highly skilled labor, special tools, and an excessive amount of time for installation, which in many instances has'made their use prohibitive.

Another important feature not contemplated by conventional flashings, is the removal of the counterflashing for repair of the roof.

The present invention aims to overcome the foregoing objections by the Provision of a flashing of exceedingly rigid construction, utilizing a minimum amount of material, in which restricted receiving grooves are entirely eliminated.

Incidental to the foregoing, a more specific object resides in the provision of a flashing in which the counterflashing receiving. portion is positioned entirely outside of the partition or wall and abuts the face of the same, thereby rigidly supporting that portion of the flashing against distortion and thus materially facilitatin attachment and removal of the counterflas ing by unskilled labor and without the use of special tools.

Another important object resides in the provision of a flashing so constructed that contiguity of the sections is readily obtained by means of a simple structure of splicing plate, insertable from the. front and rigidly secured to the sections by a simple operation.

A still further object in connection with the foregoing, resides in the adaptability of the present invention to obtaining a secure spliced joint at all corners or bends in the wall or the partition.

A further object is to provide a structure of flashing which compensates forminor irregularities between the flashing and counterflashing, thus avoiding bulging or distortion of the latter when assembled.

A further object contemplates the pro:

vision of a standard size of fiashin utilizing a minimum amount-of materia and in which that portion extending into the wall or partition may be provided with any desired width of extension to insure against the ingress of water or moisture through the changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawings is illustrat ed one complete example of the physical embodiment of the present invention constructed acording to the best mode so far devised for the practical application of the principles thereof. V

In the drawings, Figure 1 is a plan assembly of several sections of flashings constructed in accordance with the present invention and shown in that arrangement for a wall having both inside and outside cor-' ners;

Figure 2 is an enlarged section through a ortion of a wall and roof showing the fiashmg secured thereto, such view being taken upon the line 22 of Figure 1;

Figure 3 is a fragmentary sectional detail through one of the splice members, the same being taken on line 3-3 of Figure 1;

Figure 4 is a perspective of one of the straight spliced members;

Figure 5 is a perspective of the flashing before installation;

Fi ure 6 is a perspective of the splice mem er used upon outside corners, the same being shown in inverted position;

Figure 7 is a detail perspective view of a counterflashing splice; and

Figure /8 is a view similar to Figure 6 of the splice member utilized upon inside corners.

Referrin now more particularly to the accompanying drawings, and particularly Figure 5, the numeral 1 designates a section of flashing formed of sheet metal preferably of rust-proof, non-corrosive material, and which comprises a top plate portion 2 folded back along its forward edge to provide a longitudinal protruding flange 3. The material is then bent downwardly and upwardly to form .a longitudinal hook portion 4, which receives the counterflashing, as will be hereinafter described.

The rear edge of the top plate 2 is turned forwardly over the top of the plate to provide a longitudinal lip 5, which in the installation of the flashing serves several purposes, as will be more fully explained.

In applying the flashing, any desired numer of courses may be laid to form the wall or partition 6, after which the top course is coated with mortar or other masonry material, and the top plate 2 of the flashing ositioned thereon, with the back of the hook portion 4 abutting, the face of the wall. Additional mortar is then placed over the top plate and any desired number of courses built up thereon, as best shown in Figure 2.

At this point, it will be noted that the forwardly projecting lip 5, formed along the rear edge of the top plate 2, serves to engage the mortar between the courses and thus provides a secure anchor for the flashing. Here, attention is also directed to the fact that the top plate 2 is made a minimum width to insure suflicient anchorage for the flashing within the masonry. However, should it be desired to further protect the joint between the courses adjacent the flashing, an extension plate 7 of any desired width may be employed, the same being formed with a downturned lip 8 which engages in the rear lip 5 of .the top plate, thus insuring against the ingress of water or moisture, which might otherwise reach the underside of the flashing through the joint between the courses.

From the foregoing explanation of the flashing strip, it will be noted that the same utilizes a minimum amount of material, in that extensive folds are eliminated, and those folded portions utilized, being positioned adjacent the edges of the top plate, and at various angles thereto serve to provide a maximum reenforcing or stiffening of the strip, which prevents accidental bending or distortion in the handling and installation of the flashing.

Also, after the flashing has been installed in a joint, as indicated in dotted lines in Figure 2, sharp edges are so protected as to insure safety to the workmen in installing the counterflashing.

As is well known to those familiar with the installation of flashing, the same is installed in abutting sections along straight faces of the Wall, and to insure a secure joint between the abutting, faces, spliced plates are employed.

Heretofore, the construction of flashings commonly employed, required such splice plates to be inserted from the rear and upon the underside of that portion of the flashing extending into the joint. Such operation required working the splice into the mortar or masonry material, which obviously presents objections and difiiculties.

The present structure of flashing overcomes these objections, in that it permits the use of a flat splicing plate 9, which is inserted from the front and superimposed upon the top of the abutting sections, the rear end of the splice plate being engaged in the lips '5, while the front edge of the plate is provided with a downwardly and inturned lip 10, which engages the protruding flange 3 of the flashing.

Splicing of the corners, both inside and outside, is accomplished in much the same manner. Where an inside corner is being fitted, a splice plate 11 is utilized having right angle extensions 12, the forward edges of which are provided with downwardly and inturned lips 13 which engage the protruding flanges 3 of the adjacent flashing sections, as

best illustrated in Figure 1, it being understood that it is not essential to utilize separate sections meeting at a corner, inasmuch as the top plate of the flashing can be cut transversely and the flashing then bent to conform to the corner. As shown in Figure 1, it will be noted that portions of the rear edges of the splice plate 1.1 are engaged in the rear lips 5 of the adjacent flashing sections.

Where an outside corner is fitted, the splice plate 14 is employed, which is also provided with right angle extensions 15, but in this instance, the downwardly and inwardly turned lips 16 are formed along the outside edges of the plate and engage the protruding flanges 3 of the adjacent sections in the manner as heretofore described.

lVhile splices for straight abutting sections and for inside and outside angles, have been illustrated and described in some detail, it is to be understood that the principle employed may be applied to any bend or irregularity in the face of the wall or partition, regardless of the shape of such bend or irregularity.

After the flashing has been installed, as indicated by dotted lines in Figure 2, the counter-flashing 17, comprising an apron portion 18 terminating at its upper edge in an angularly projecting lip 19, is assembled thereon, by inserting the lip 18 over the longitudinal hook 4 of the flashing, as indicated in dotted lines in Figure 2.

The hook 4 may then be readily closed by the use of any tool or block of wood, it being merely necessary to hammer the upper edge of the flashing inwardly against the face of the wall, as best seen in Figure 2. Thereafter, if desired, the protruding flange 3 can be turned down ata slight angle to further protect the joint between the flashing and counterflashing and serve as a drain or water shed.

Here, it will be noted that the hook 4 of the flashing terminates a slight distance from the protruding flange 3, and therefore should any irregularities exist between the flashing and counterflashing, the same will be compensated for, which will prevent the counterflashing from bulging along its lower edge, which is a fault quite common in numerous types of flashings.

Where it is desired to join sections of the flashing 17 a splicing plate 20 is utilized, which conforms in shape to the counterflashing and is merely superimposed thereon, as

,best shown in Figure 7. a

From the foregoing explanation, it will be quite apparent that a very simple, inexpensive flashing has been provided, which employs a minimum amount of material and materially facilitates not only installation, but also removal of the counterflashing when it becomes necessary to repair the roof, inasmuch as the protruding flange 3, if turned downwardly, can be raised with little difficulty, and the hook 4 loosened to permit withdrawal of the counterflashing without sufficient damage to the flashing to prevent replacement of the counter-flashing, after repair of the roof has been effected.

. It will also be noted that a very simple form of, splice has been provided which not only effects a secure tight joint at all corners or bends in the wall or partition, but which also materially facilitates the operation of assembling and attachment of the splice plates to the flashing, it being readily seen that after the protruding edge 4 of the flashing is turned downwardly, as illustrated in Figure 3, the splice plates are securely held against detachment.

Furthermore, it will be seen in the completed installation that excessive projecting edges are eliminated, the flange 3 being the only outwardly projecting portion, and this being of double thickness with a turned edge offers a rigid structure, not readily subject to damage.
