COUNTERFLASHING AND ANCHOR CAP THEREFOR Filed Jan 7. 1952 III Patented June 9, 1953 oFFIcE COUNTERFLASHING AND ANCHOR CAP THEREFOR Lewis B. Coleman, Cheyenne, Wyo. Application January 7, 1952, Serial No. 265,226

Claims. (Cl. 10826) The present invention relates to certain new and useful improvements in metal fiashings, generally speaking, and has more particular reference to a cap unit and a complemental counterflashing unit wherein coacting portions of the two units are readily interconnected by way of novelly constructed intimately cooperating assembling and retaining means.

Those who are conversant with flashing constructions and the attending perplexing installation problems encountered by roofers and sheet metal workers in the building industry are aware, of course, that many and varied styles, forms and special structural adaptations have been contrived by others with a view toward solving such problems. Nevertheless, and notwithstanding the many prior art contributions which have been offered, time and labor saving requirements still remain unsolved. The fact that prior art achievements have, evidently, not met with widespread adoption and. use apparently accounts for the efforts which are being herein put forth for more general and satisfactory acceptance and endorsement by sheet metal workers and roofers.

Another general objective is to provide highly practical structural means which is susceptible of expedient handling and ready installation and, in so doing, to thus provide an improved con struction in which manufacturers and userswill find their respective requirements and needs amply met.

More specifically, the invention has to do with a special structural adaptation which is charac terized by a cap section or unit which is installed as the brick-work is erected, a' complemental counterflashing section or unit which is installed after the roof is applied and the base flashing is in place. The first unit has an apron provided with a channel-type receiver having guarded shoulder means, an edge portion of the counterflashing unit being fitted telescopically into said receiver by merely sliding it up and into" place, said counterflashing unit having resilient detents engaging shoulder means within the confines of the receiver. The finished structure provides a neat, weather-tight counterflashing which aptly and satisfactorily hugs the wall surface and the coacting upstanding portion of the aforementioned base flashing. g

- Other objects, features and advantages will be come more readily apparent from the following description and the accompanying sheet of illustrative drawings. g p g W A in the accompanying drawings wherein like 2 numerals are employed to designate like parts throughout the views:

Figure l is a View in section showing fragmentary portions of a common wall, a roof, base flashing and the improved cap and counterflashing unit and their construction and mode of interconnected association and use.

Figure 2 is an enlarged fragmentary perspective view showing cap and counterfiashing sections or units grouped together and further illustrating the structural components or details embodied in each unit.

Figure 3 is a perspective view showing the man ner in which two cap units are interconnected for assembly use, the receiving channels having their flanges or wall portions spread apart to further illustrate details.

Figure 4 is a perspective view showing two of the cap units directly joined together at coacting ends with terminal portions overlapped.

Figure 5 is a fragmentary perspective view of one end portion of one of the cap units, observing the same in a direction from left to right with reference to the cap unit in Figure 2, and showing a slight modification wherein the lefthand end of the receiver terminates short to accommodate certain assembling requirements.

By way of brief reference to the detailed description the preferred embodiment of the assemblage comprises a cap unit embodying a fiat plate having an upstanding keying flange along an inward longitudinal edge and a depending lengthwise apron along an outward longitudinal edge, a lengthwise inverted U-shaped counterflashing assembling and retaining channel opposed in parallelism to an interior surface of said apron and joined to the lower edge portion of said apron by way of an integrating bend, said channel embodying an outward flange, an inward flange and a bight portion interconnecting said flanges, said inward flange having shoulder means interposed between said flanges, and a counterflashing embodying aplate portion having an edge portion fitting between said flanges, said plate portion having resilient detent means engaging and held in position by said shoulder means, whereby said counterflashing is interlocked with said apron by way of said channel,

Specific reference is made to Figure 1 wherein the wall, here shown as a brick wall, is denoted at A, said wall embodyingbricks B having mortar bonds therebetween. Thefragmentary'co acting portion of the roof is denoted at D while Eoenote's a commonly known cant strip. The roof covering is'denoted at F and-the bass net 3 ing at 6, the latter having the familiar upstanding complement H which contacts the surface of the wall and with which the improved units cooperate to provide a neat weather-proof seam or seal.

The sheet metal cap unit is denoted by the numeral 8 and this may be made of any material such as galvanized iron, copper or aluminum or whateverlithe architectspecifies. {is before n ien tioned, this 'is-characterized by a single piece of sheet metal which is bent upon itself to provide a substantially flat plate l having a perpendicue lar or upstanding flange along on e longitudinal edge. This plate is embedded-in themortar and the flange serves as a key or anchor in a well known manner. The outstanding longitudinal; edge portion of the plate has an outwardly and downwardly inclined bend It which donstitutes" a junctural web between the plate and thedepending apron IS.

In Figure 5, this same principle applies but here the channel means l8 merely terminates inwardly of l0, l4 and I6. The essence of the invention is, of course, revealed almost wholly in Figures 1 and 2, particularly Figure 2.

Minor changes in shape, size, materials and rearrangement of parts may-be resorted to in actual practice provided no departure is made. from the invention as claimed.
