(Cl. 10S-26) This invention relates to roofsV and more particularly to a flashing assembly for a roof.

It is an object of this invention to provide a hashing assembly for brick parapet walls in which a shaped brick or form cooperates with a special member to provide a flashing groove.

Another object of this invention is to provide a flashing assembly, whichcan readily be built into a brick wall, in which a recessed brick, having a composition and coefficient of expansion similar to that of common bricks, cooperates with an overlying metal section to provide a flashing groove.

, ous types of ilashings or roongs.

Other objects and advantages will appear from the following detailed description of the invention.

In the formation of hashing assemblies, it has been common practice heretofore to cut out or chisel away a portion of the finished walls to form horizontal grooves for the reception of the edges of the flashing. Such cutting of walls is timeconsuming and costly and weakens the walls to a considerable extent.

I have invented a flashing assembly which can be built into a brick wall during the ordinary construction of the wall and which provides a fiashing groove for the inserti-on of any of the vari- This fiashng assembly in its preferred embodiment comprises a brick and a cooperating member or section, preferably of metal, adapted to be placed over the brick and forming therewith the flashing groove. This brick may be specially fabricated, or where desired, it may readily be made by cutting away portions of ordinary brick. In either case it has no overhanging portion liable to fracture and requiring special handling in transportation. Self aligning metal sections may be employed and applied with their ends lapping to form a continuous flashing groove running the full extent of the` parapet walls. n

The invention will be understood from the following description taken in connection with the accompanying drawing illustrating a preferred embodiment of the invention and in which the same reference characters are used to designate the same parts in the different views.

Fig. 6 is a vertical section through a portion of a brick wall showing a modified flashing assembly embodying this invention.

Fig. 7 is a vertical section through a portion of a brick wall showing another modied form of the flashing assembly.

Referring to the drawing and more particularly to Figs. 1 to 5, numeral I designates a roof deck Acovered with suitable roofing 2, such as the usual built-up sheet and pitch roofing. A contiguous parapet wall 3 rises, as is customary, above the roof deck. Flashing assembly a, the component parts of which are more fully described below, is incorporated in wall 3 to provide a ashing groove or receptaclel 5 `extending upwardly and inwardly from face B of the wall 3 at a point a short distance above the roof deck i.

A cant strip or board 8 may be placed in the angle between the roof deck I and the brick wall 3. Roofing 2 extends up over the top of the cant strip. As shown in Fig. 1, the cant strip may be so placed that the surface of the roofing on the cant strip is substantially in alignment with the bottom face of the hashing groove 5. Flashing 9 overlies the roofing 2 and extends into the flashing groove as shown on the drawing.`

The flashing assembly 4 of this invention comprises a. shaped brick II having a recess therein and a member or section I2 adapted to cooperate with the brick to form the groove 5 for the reception of the hashing.

Brick I I, shown more fully in Figs. 3 and 4, may be of generally rectangular shape and, although not limited thereto, in the case of a wall built with common bricks may have overall dimensions equal to those of common rectangular .building bricks. In the embodiment of the invention shown in Fig. 3, portion I3 of the brick I I extends upward at an angle to the perpendicular from edge I4 to a point I5 some distance inward where it joins face I6 rising vertically to edge I l on horizontal upper face I8. There is thus provided an inwardly and upwardly inclined surface I3, constituting the lower face or bottom of groove 5, and a vertical face I6 constituting the inner end of groove 5. Surface I3 is preferably inclined at an angle of 45 Member or section I2 is preferably made of metal, such as sheet copper or galvanized sheet iron, of suflicient rigidity to retain its shape when bent into the desired shape. As shown in Figs. 1 and 2, member I2 may comprise a flat portion 2I adapted to lie horizontally on the face I8 of a recessed brick II. Extending from portion 2I is a perpendicular offset 22 having an upwardlyextending flange 23 and a downwardly-directed flange 24. A depending portion 25 extends at an obtuse angle to the flat portion 2|, and forms the upper face of inclined groove 5. Depending portion 25 extends preferably at an angle of 135 to portion 2| so that when the metal section and the shaped brick are assembled in the proper relationship, the depending portion 25 will lie substantially parallel to the inclined surface I3 of the shaped brick.

A face 26, adapted to lie in the plane of the face 6 of the wall, extends vertically upward from edge 2 of the depending portion. As shown in Fig. 2, edge 2`I of the metal section is provided with a plurality of spaced perforations or holes 29. On line 30 the face 26 bends inwardly with respect to the exposed facev of the wall and upwardly in a direction substantially parallel to the vdepending portion 25. This upwardly-inclined portion or offset, designated by numeral 3I, is preferably provided with a series of corrugations or ribs 32 extending longitudinally of the section. Each metal member I2 is preferably made of a length that it may be readily handled, e. g., 6 to e 8 feet. f

The :dashing assembly, i. e., the brick and the metal member, is adapted to be incorporated into \brick wail as follows: Bricks 33, which may be the usual clay bricks each 8 inches long, 2% inches high, and 4 inches wide, or of any size or shape employed in building construction, are laid in the usual manner with mortar 34 to provide horizontal courses designated by numerals 36, 31, and 38. Instead, however, of forming the inner longitudinal row of course 38 of standard or commonbricks 33, shaped bricks II are employed. Bricks I-I are laid end to end with edges I4 in line with the face 6 of the wall.

After bricks II have been set in place, metal members I2 are disposed thereon in such manner that the at portion 2I of each metal member rests on the surface I8 of an underlying shaped brick, and the depending portion\25 of each member extends in spaced parallel relationship to the inclined face I3 of a shaped brick to form the intermediate upwardly inclined groove 5. Flange 24 abuts against face 40 of brick II and provides a'means for readily placing the two parts of the assembly in the proper alignment and for holding the member I2 in position. 'I'he face 26 of each section should lie in the plane of the face 6 of the wall. Since each metal member or section is preferably about 6 to 8 feet in length, one section covers a plurality of the shaped bricks, each of which `inay be only 8 inches long. The ends of adjacentmetal sections may be overlapped or locked as indicated by reference character 4I shown in Fig. 5. There is thus formed what may be considered a continuous metal surface extending over the underlying course of shaped bricks and'providing a leak-proof flashing to-a depth of 4 inches into the wall in the case of a wall made with bricks 4 inches wide. After setting the metal sections in place they are illled with mortar to provide a bond for an overlying course 42 of bricks 33, shown in Fig-1 as a headerY course.

l When the wall is formed in this manner the edge of flange 23 abuts against the underface of the overlying brick course 42 and acts as a guide in laying this course. Flange 23 also acts as a water stop and directs any water which may seep into the wallabove the metal section back over the depending portion 25 of the section and out through perforations 29 onto the face of the flashing. Upwardly inclined portion or offset 3i also has the tendency to direct water which may get into the wall back toward the face 6 of the Wall. Corrugations 32 on this inclined portion also aid in holding the mortar lying thereover which is used to point up the face of the wall. If desired, the corrugated inclined portion may be bent upward so that its edge will abut against the lower face of the overlying course 42, thereby preventing the mortar used in lling the metal section from running out over the face of the wall before it has set sufliciently to retain its shape. This is especially desirable if a thin mortar is used.

Fig. 6 shows a modified flashing assembly. Brick 44, shown in this figure, is similar to brick II, described above, with the exception that the inclined surface, forming the bottom of the ashg ing groove, does not begin at the forward edge I4 of the unit. This brick has a portion 45 rising vertically from edge I4, an inclined corrugated surface 46 extending inwardly from portion 45, and a second vertical portion 4'I constituting the inner end of the groove. Metal section 49, which cooperates with brick 44, is provided with a relatively long face 50 extending vertically upward from depending portion 25, and a short flange o'r offset 5I extending perpendicularly to face 50. Face 50 is of such a length that the flange 5I will lie over and contact with the upper surface of the bricks 33 in the next overlying course 42.

In Fig. 7 is shown another type of assembly embodying this invention. Shaped brick 53, shown in this modification, is similar to brick I I with the exception that its inclined face, denoted by numeral 54, has a flat or plane surface instead of a corrugated surface. Metal section is similar to section 49 of Fig. 6 with the exception that the fiat portion 2I, adapted to rest on the shaped brick, is omitted. In its place member 55 is provided with a vertical face 56 adapted to fit against vertical surface I6 of the brick, an inclined face 5'I adapted to fit over the inclined face 54 -of the brick, and a vertical flange 58 adapted to fit against the face 6 of the wall. Cant board 8 is shown in Fig. 7 in alignment with the lower face of the inclined groove. This position of the cant board is especially desirable when the roofing itself is to be inserted in the inclined groove rather than ending at the face 6 o f the wall as shown in Fig. 1.

- It-will be apparent from the above description of this invention that my flashing assembly is both simple and durable in construction and involves the use of readily obtainable materials. The assembly can readily be installed during the norexpansion asstandard bricks, in forming the wall with such bricks in accordance with the invention the occurrence of cracks and iissures in the wall, due to uneven expansion and contraction, will not take place. It will be noted that water seepage into the inner mortar joints of the Wall is hindered by the vertical water stop at the inner edge of the metal section and by the inclined offset near the face of the metal section.

The term brick" is used in this specication in a broad sense and is intended to include all stone, metal or other structural elements irrespective of shape, employed in building construction to'form structural members such as walls. y
