FLASHING CAP RECEIVER Filed April 10, 1970 3 Sheets-Sheet rs United States Patent thee Patented Sept. 28, 1971 ABSTRACT OF THE DISCLOSURE A flashing cap receiver is described which has a receiving chamber formed by a pair of horizontal portions one of which has a median protrusion portion extending toward the other horizontal portion. The chamber is adapted to receive and hold a flashing cap member having a bent over end lip whose width is no greater than the distance between the protrusion and the back of the chamber.
BACKGROUND OF THE INVENTION This invention relates to flashing and in particular to two-part flashing wherein one portion known as the receiver, is embedded in the wall of the building and has an exterior projection to which an exterior flashing member or cap can be attached to complete the flashing system.
Two-part flashing systems, as have previously been described, have suffered from one or more deficiencies. Thus, the components had to be prefabricated and could not be readily formed on site. Also, several prior two-part systems were difficult to attach and often needed lead plugs. In addition, some prior systems could be loosened and separated by inclement weather.
The object of the present invention is to provide a factory formed or shop formed through-wall flashing system that can be easily installed on the job site during construction without tools, eliminating malleting or bending metal in the field.
A further object of this invention is to provide such a flashing system wherein the external member easily attaches to the embedded member and provides a firm weather resistant connection which does not require any lead plugs.
Another object of this invention is to provide such a flashing system which can be adapted for all common gages for all roofing and flashing metal.
SUMMARY OF THE INVENTION The invention comprises generally a flashing cap receiver formed from a single sheet of metal and adapted to be partly embedded in the mortar of a masonry wall. The receiver comprises in sequence, a vertical portion, a horizontal portion extending outwardly, a second horizontal portion extending out and back containing a depressed protrusion, a third horizontal portion extending under and forward and a downwardly depending terminal portion. The second and third horizontal portions form a receiving chamber adapted to receive and firmly hold the exterior member. Any flashing cap member can be used which has a bent over end lip insertable in the chamber and has a width no greater than the distance between the protrusion and the inner end of the second horizontal portion.
The flashing cap receiver of this invention can be formed from various metals such as copper or stainless steel or from laminates or other weather and water resistant meterial having similar dimensions and strength. Metal and metal laminates are generally preferred because they permit a snap-in action of the flashing cap member into the flashing cap receiver.
The present invention is applicable to a wide variety of through-wall flashing systems.
BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a partial sectional view of one embodiment of this invention shown embedded in the mortar of a masonry wall.
FIG. 2 is a perspective view of the flashing cap receiver of this invention in proximity to a flashing cap.
FIG. 3 is a rear view of a flashing cap receiver of FIG. 2.
SPECIFIC EXAMPLE OF INVENTION The embodiment of the invention which is illustrated in the drawings comprises a flashing cap receiver 11 adapted to receive and hold a flashing cap 21. The flashing cap receiver 11 comprises in sequence a vertical portion 111, a first horizontal portion 112, which extends outwardly to a second horizontal portion 114 which is bent under and inward at edge 113 and has a depressed portion 115, a third horizontal portion 118 which is bent outwardly and under at edge 117, and finally a depending portion 119. The second and third horizontal portions 114 and 118, together with the depressed portion form a receiving chamber. The flashing cap 21 has a front edge 212 and a bent over lip 211 which fits into the chamber and can be snapped beyond depressed portion 115 to seat in the rear chamber 116, the width of lip 211 being less than the width of chamber 116. The remainder of the structure of the flashing cap 21 can be varied and in the illustrated instance has angular depending portions 214 and 215 terminating in an outward bent over lip 216.
A flashing cap receiver 11 is shown embedded in the mortar 31 of a masonry wall 30 with its chamber portion deeply embedded in the mortar between upper and lower cement blocks and 151. The exterior portion of the wall has an asphaltic facing 32 and tar gravel layer 34. Facing 32 is covered by the depending flange 119. Thus, any moisture which has penetrated to the exterior portion of the wall into the mortar joint is conducted by the flashing member 111 out of the walk to tip 113 and then down over portions 214, 215 and 216 of the flashing cap. Likewise, any exterior drainage is carried outwardly and down the flashing cap receiver.
The facing 32 is preferably made from multiple layers of flexible, asphaltic sheets, as for example asphaltic felt or asphaltic paper. As shown in the drawings, at least one layer extends up the outside wall of the building underneath the cap receiver lip 119. The facing 32 is supported angularly by exterior wood member 33 to assist in its drainage function.
The flashing system of this invention has been found to provide a rugged, non-leaking seal against driven water. Further, it is inexpensive and rapid to install, with a minimum of labor.
