JOHNA. DoGiiNDoRF, or; nnrnoi'r, MicHIGAN FLASHING. I

AApplication ined July .16,

This invention relates to flashing retainers, and the obJect is to provide a new and improved means for securing a lashingto ar wallor chimney. l Y

Heretofore, in this art, especially with met al roofing, it has been cominon'practice where the roofing contacts the sideface of a wall or a chimney to extend the'metal a short distance and insert the edge in a groove commonly termed a raglin, provided between courses of bricks and secure the saidedge therein by means of wedges. Suchpreviousmetliod is inadequate in that the wedge members become loosened after la period of ilse and the in# sei-ted edge of the roofing becomesfdisplaced and it is alsoa rather expensive operation to secure the edge of therooling in place in the manner stated.

My present invention seeks to obviate these various difficulties Varising 1n theprevious methods andy t'o provide a separate channeled Amember which is laid in place between two courses of brickor stones at the time of erection of the wall providing a recess into which the edge of the roofing member may be readily yinserted and avoiding the labor involvedin removing la portion of the mortar, the member being hanged to engage over and securelyy fasten the flashing in place therein thusk avoiding the use of wedges.

These objects and the various novel features of the invention Aare hereinafter more fully described and claimed,` and the preferred form of construction of a flashing retainer embodying my invention is shown in the accompanying drawings in which- Y Fig. 1v is a sectional View of a roof and a parapet showing the general arrangement of the flashing and flashing retainer.

Fig. 2 is an enlarged sectional view thereof at the time the edge of the flashingis in- Ytroduced into the flashing retainer.

Fig. 8 a similar section showing the com-l Vpletion of the securing of the flashing in place.v Fig. 4 is a perspective view of a strip of p my improved ashingretainer.- n

Fig. 5 is a section longitudinally of two such strips whichV are inserted endwise one in the other laying a flashing of greater length than a single strip.

Fig. 6 is an alternative form of construction.

My improved flashing retainer consists of al member'l which is preferably made of a copper sheet turned upon itselfto provide a nar- 1927.1 semi ne. 206,183, f

in width than the thickness ofthe metal sheet or. flashing to befinserted therein. y One of the edgesy 3 of this strip is bent approximately at a right angle outwardly as shown and the other edge 4 is also bent at a ,slight angle l lrow channel indicated at2 butslightly greater in the saine directionas tlielmember 3 providing a comparatively wide throat for `the l.space The sheet in its two opposite side .walls is punched at regular intervals longi-l tudinally'of the strip as indicated in Fig.4

to provide inwardly extending points 6. and 7 which are in registration when the ksheetfis folded and provide a means for holdingl the y,

two side walls ofthe retainer in the desired spaced relation, the purpose being to prevent 'the walls of the flashing from being forced together when laidin the mortar yand under pressureof. the brick or vstone thereabove.v These retainer strips are preferably made of copper in. order thatthey, shall berustproof Y r`and provide permanent installation so that,

even tho the flashing introduced therein may rust out, the retainer being la permanent inrstallation is used when the roof is repaired and the edge of a new sheet introduced-there.-

in. `Preferably the inner face ofthe strip forming thechannelis turned or galvanized to prevent adherence of the flashingther'ein. lt will be readily l'understood :from the drawing that in the laying of the wall or the` chimney with which the flashing retainer is to be used, it islaid upon the brick orstone as the case'may be at the desired heightabove Y the roof usually about six to eight inches and the wall .is thereafter completed in the usual way. Vhe'n laid in the wall lthe member is practically as shown in Fig. 2 with the edges 4 and 5 in the spaced relationas is shown in Fig. 4 which is vthe form at the time of inf stallation providing a wide guide opening or 'throat for introduction of the edgev 8 of the roofing sheet `9. Usually Vsuch metal roofing y is laid over 4one or more layers fof roofing paper indicated at 10 which extend across Athe roof surface and for a distance up the face of the wallas indicated at 11. Themetal roofing lplate 9 lays thereover and extends upward :along the side wall or chimney or -otlierfstructure astlie case may be and the 3 thus efiectually securing the flashing in place andV eifectually preventing any ac-y cidental removal or leakage.

As previously stated, the flashing member; l is made preferably in unitorm lengths ot from six to eight feet and, for use in wallsmanner for a short distance the purpose bei ing to prevent any break in the continuity of the flashing ietainer although it is to be understood that the invention is not confined to such use of the parts.

In Fig. 6 I have shown an alternative form of construction of the retainer. lith this form the upper wallet the strip extended as at lObeyond the lower wall which extends to approximately a point indicated at 1l and at the opposite end the lower wall is'extended as at l2 beyond the end ot Vthe upper wall at 13. The length of these extending portions may be as desired but preferably not more than two inches.A In laying such strips in endwise relation the extending end portion yLl 10 of the upper wall lays over the extending portion l2 of the lower wall of the adja cent strip and thus the joint which would then be formed between the end 100i' one strip and the end 13 of the adjacent strip does not alignl with the joint between the adjacent ends of the lower vwalls 1l and l2 as will be readily understood. Also, iii the laying of the metal roofing the joints between sheets thereof should bieak joints with the joints in the flashing retainer. This insures prevention of leakage. V

In the construction of the retainer the depressions may be of much greater area than shown in Fig. l and of a form 'for instance as suggested in Fig. 6 at lll. These provide pockets in the outer faces of thepwalls of the retainer in which the mortar engages and as these depressions are preferably formed in both walls, as in the forni shown in Fig. l, the projections thereof into the channel lie in contact and prevent a collapse of the channel under pr ,ssure Other means, however, may

be provided to hold the channel walls in the spaced relation necessary for introduction of a flashing.

From the evident that my improved flashing retainer is comparatively simple andinexpensive in construction; provides a means permanent in Vforegoing description Vit becomes character through which a metal or other character of sheet roofing may be readily introduced and secured in place without liability of its later becoming loosened and per-v mitting leakage. As to this point it is to bewnotedV thatthe width of the member is such as to extend into the wall in which it is supported to sufficient distance to insure its retention and, inasmuch as the member isA laid inthe mortar, the depressions forming the inwardly projecting points and 7' become filled with the mortar thus insuring the retention of the retainer in place.

I claim: f 1 Y l. A flashing i'etainer consisting of a metal sheet bent upon'itself providing a narrow longitudinal channel, an edge of one side wall being outwardly bent providing a comparatively wide threat opening to the channel, means tending to prevent the side walls from Vcollapsing under pressure, the retainer being Aformed in strips of the desired length with the upper wall at one end extendingbeyond the lower wall and the lower wall at theopposite end extending beyond the upper wall `whereby in laying the strips the projecting upper wall of one strip lies over the project# ving lower wall of the other strip.

2. A hashing retainer adapted to receive the edge of a ashing,;consisting ci' a sheet einen-corrosive metal bent upon itself to form a narrow longitudinal channel, 'the outer edge of the walls defining lthe channel being so arranged as to provide a comparatively wide throat leading to the space between the said walls, the upper and lower walls delining the channel being approximately of the same length andthe upper wall extending at one end to beyond the end of the lower wall and the lower wall at the oppositeend extending beyond the end of the upper wall, each of said extensions having portions on the side of lthe bend extending-inwardly from the plane oit the respective wall whereby in laying the strips the projecting end of the upper wall of one strip lies over the projecting end otl the lower wall of the adjacent strip with the said inwardly extending portions practically in registration, at least one of said walls having depressions formed in its outer surface providing lugs formaintaining the walls in spaced relation, said lugs being at aV distance vfrom the throat to permit insertion of the -edge of a flashing.
