Filed Sept. 19, 1939 Patented Aug. 19, 1941 UNITED STATES AT'ENT OFFICE ROOF FLASHING 7 Hal Oallaway, Los Angeles, Calif. Application September 19, 1939, Serial No. 295,610

5 Claims. 7 (01.108-26) This invention relates to flashings for roofing, or the like, and is more particularly related to the flashing of brick or other masonic walls.

In the connecting of angular walls to form a Waterproof connection, as for example in the connecting of roofing with a fire wall, deck wall,

wall parapet or the like flashing and counterfla'shing have heretofore been utilized. The particular problem presented, however, has been to so connect such a wall with a roofing material as to enable the formation of a waterproof connection in an inexpensive manner, using a minimum of labor, to provide a neat appearing connection which is readily detachable to permit inspection h provide a means of forming a waterproof connection between a roofing or wall material and a masonic wall, which will be of permanent char- 'acter, easily applied, or removed as desired or required.

Another object of this invention is to provide a means of forming a waterproof connection between a masonic wall anda roofing or like wall, floor or roof material which includes a flashing adapted to be embedded within and secured to the masonic structure, a counterflashing adapted to overli the said wall material, and an interlocking means for releasably connecting the flashing and the counterflashing, and wherein a waterproof or resisting connection is formed between the flashing and counterflashing.

Other objects and advantages of my invention it is believed will be apparent from the following detailed description of a preferred embodiment thereof as illustrated in the accompanying drawing, wherein for convenience I have illustrated my invention as in use in flashing a brick fire wall to a composition sheet roofing. It will be apparent to those skilled in the art that this illustration is only one adaptation of my invention given for the purpose of description, explanation of its principles and mode of operation.

In the drawing:

Fig. 1 is a perspective view of a roof or deck and fire wall illustrating the flashing as embodying my invention as adapted thereto.

Fig. 2 is a fragmental transverse perspective section thereof during laying of the brick or other masonic block or stone.

Fig. 3 is a detached fragmental perspective sectional view of the flashing and counterflashing of my invention.

'2 formed of suitable concrete.

Fig. 4 is a detached perspective view of the flashing tie plate of my invention.

Fig. 5 is a detached perspective view of the locking band embodied in my invention illustrating in dotted lines the band as bent to locking position.

Fig 6 is a fragmental sectional perspective view of a modified form of flashing, counterflashing and releasable locking means embodying my invention.

Fig. 7 is a detached fragmental perspective view of the counterflashing and attached locking band of my invention as illustrated in Fig. 6.

The preferred embodiment of my present invention is particularly adapted for use in connection with brick, stone, or other masonic walls wherein the wall structure is constructed of superimposed bricks or the like connected together through the medium of suitable mortar, cement, or the like.

In this modification of my invention the deck or fire wall I is illustrated asofvsuch masonic structure connected at the edge of aroof or deck Roofing material 3. which may be any suitable material which is commonly referred to as roofing paper, composition or metal, is laid upon the surface of the roof 2 so that its edge portions 4 extend up the inner surface of the wall 1. The flashing. embodying my invention includes flashing members 5 which are laid in the masonic. wall I during its construction between the bricks or othermembers forming the wall. Thus the flashing members 5 are positioned as indicated in Figure 2 and are secured in position through the medium of their horizontal flanges l which terminate in the hook flange 8. The vertically extending skirt 9 of the flashing 5 terminates at its lower end in an outwardly diverging securing flange l0 having locking means receiving recesses IL. The flashing 5 is held in position by means of tie straps l2 which are so formed as to include a locking detent l3 into which the hook flange 8 fits and at its opposed ends with downwardly extending holding flanges I4 and I5 which are spaced apart a distance corresponding with the width of bricks 6 or other masonic element used in the formation of the wall I.

The members [2 are formed of a bendable material such as galvanized plate so that they may be bent to conform with the dimensions of the said masonic members, particularly at their rear flanges l5. After the flashing 5 is thus secured in position, the mortar, cement or other material is spread over the members 12 and. the horizontal flanges 1 and the next layer of bricks or the like added until the wall is completed. Thus the flashing 5 is embedded within the cementitious material used to form the masonic Wall I. The counterflashing It in this modification of my invention may consist merely of a strip of galvanized sheet metal of such width as to extend under the skirt 9 and over the upturned edge 4 of the roofing material 3. When thus positioned, the counterflashing I6 is secured in position through the use of locking strips H which are preferably formed at their lower end to provide hook sections I8 which are adapted to book under the edge of the counterflashing IS. The upper locking ends of the strip 11 are then extended through the recesses II and bent over as indicated at I9 to lock the counterflashing IS in position. During this locking, a definite tension is imposed upon the locking strips [1 as they are bent over the angular flange I so that the yielding of this angulated flange provides a resilient holding in position of the counterflashing [6 whereby the upper edge 4 of the roofing material 3 is clamped against the inner surface of the wall I.

In case repair or re-roofing or inspection of the roofing is required at any time, this may easily be accomplished by merely removing the locking strip l1 and the counterflashing [6, thereby enabling easy access to the upper edge of the roofing material 4. Obviously the flashing may be again completed after inspection without the necessity of providing new or additional counterflashings or securing means.

In the modified form of my invention as illustrated in Figures 6 and 7, similar parts have been indicated with similar numerals with the addition of an exponent a thereto.

In this modification of my invention, all parts are similar to those heretofore described with the exception of the locking strips I! which are here illustrated as being secured through the use of suitable securing elements such as riveting or welding the same to the face of the counterflashing I6 as indicated at 20 In this modification of my invention the locking strips I! are'slightly bent outward so that they may be easily inserted through the locking recesses Il of the flashing to be bent over as indicated at H in the same manner as described in connection with the first modification of my invention.

In order to prevent undue rubbing and wear of the upwardly extending portion 4 of the roof 3, I prefer to bend the material forming the counterflashing l6 and I6 upon itself as indicated at 2| and 2| respectively.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my invention is of the full scope of the appended claims.
