FLASHING FOR BOOFS OR THE LIKE.

Application filed January 24, 1927. Serial No. 163,052.

. I v My present invention relates in general --to roofs and the like weatherproof coverings, and has particular reference to a so-called flashing for sealing and anchoring the end -of root coverings and gutters at their juncture with walls, chimneys and other terminals or obstructions.

- chimneys and the like locations.

Various ex pedients have been carried out to eflect a weatherproof seal'ztor the roof covering, some of which, while eifective for all practical purposes, require considerable effort to build. Othersmore easily made are not always as eflective as they should be,-

and very often unsightly.

lVith my invention I can prod ce not only a positive seal, so to speak, but one which will be'unusually neat in appearance, easy to install and cheap to produce.

In the accompanying drawing, which illustr'ates several embodiments of the invention Figure 1 is a perspective View of a portion of a wall'showing a roof covering adjacent thereto, and illustrating the application of the invention.

Figure 2 is a perspective view in detail of one part of the flashing strip.

Figure 3 is a perspective view in detail of a companion part of the flashing strip.

Figure 4 is a view in cross-section showing one way of anchoring the roof covering in the flashing strip.

Figure 5 is a similar view showing a slightly modified way of anchoring or securing the roof covering in a flashing strip; and v Figure 6 is a view in cross-section showing a similar modified form of flashing strip. Referring now to the drawing in detail. For the purpose of illustration I have shown a brick wall 5, 6 representing a roof'witha flexible covering 7 therefor. The difliculty heretofore experienced has' b'een to make some kind of a positive seal for the termination of the covering 7, so as to realize a .completely sealed waterproof covering. for

the root. v

According to my invention I propose to usepractically a two-part flashing strip,

consisting of a base section 8 and ,a .cover section 9. In Figure 3 these parts and 9 can u sually be made inelongated strips of 2.

ends adapted to abut one another so that several of the sections'may be used to develop a flashlng-strip along the side of a relatively long wall.,or the like. As shown -in Figure l the flashing strip is installed as length suitable for the purpose, with their an insert, so to speak, in a brick structure.

For thispurpose it would be desirable to make the depth ofthe base 8 equal to that of the depth or thickness of an ordinary build ing brick. The width of the flashing when the cover 9 is applied to the base 8 should be equal'to that of half of a brick, so that the flashingmay be installed in the brick structure without special arrangements. In other words it would simply take the place of the bricks for the length of the wall re quired for the flashing.

The base 8 iscmade with a modified rabbeted or mortisededge, made to accommodate the cover 9, so that the concave underside. 10 of the cover9 will fit over the convex surface 11 of the base, and with the vertical side 12 of the cover fitting against the vertieal edge 13 of the base. This makes up a mortised joint. flashing strip may be conveniently and cheaply made from an extruded, flbrated asphalt composition. In other words, the strip is. made up of sections 8 and 9. The sections whenjoined should have some qualities of compressibility, although'rigid and strong enough to. enter into the wall construction without interferingv with the supporting-qualities of the brick work. I preferably' make the flashing strip. of fibrated asphalt composition in order to obtain compressibility and waterproofing qualities of the flashing, and also for cheapness and con: venience in manufacture.

r In installingthe flashing the brick workwill be carriedon up to where the flashing is to be installed, then the 'base 8 may be inserted in its proper 'position and the brick work carriedon as required. When the time comes to lay. the roof covering 7 the I edge of the same may be laid over the base of the flashing, and the cover?) then inserted and hammered, or otherwise forced into place.

in Figure 4. This impaling means will pass As shown in Figure '5 I may use a layer These two parts of the- To securely anchor the end oi the covering in the flashing, .nails or other impaling means 14 may be employed as shown I v adapted to enter into engagement with one or coating of mastic, or the like, on opposite sides of the inserted edge of the covering to effect a more positive seal if desired.

The impaling'fneans 14 may or may not be used in this combinati0n.' l

In Figure 6 I have shown dove-tailed slots'16 in the. underside and top of the base 8, and in thetop of the cover 9. The

purpose of these slots is to interlock with the plaster or mortar of the brick work .so'

as to hold the flashing .strip in. place? If usin a cover 9 with slot 16 therein it would 'not. 'e altogether practical to insert the cover .9 after the brick work had been car-. -15

ried beyond the flashing strip: For. this a reason it would be more desirable in using this form to terminate the'brick work at the flashing and install and lock the flashing, in place before carrying the brick work, on. i

As will be seen from Figure 1 I am enabled to. develop an exceedingly neat and practical flashing, and particularly one which makes a most eif'ec tive weatherproof seal betweenthe roof covering and the wall, or other surfaces presented at right angles thereto. The flashing is easy to install, easy and cheap to make and, as stated; unusually effective. i a

A flashing of the class described, comprising separable companion members adapted to enter into engagement with one another to provide a joint between them for the reception of the edge of a roof covering, said members being formed of a homoeneous mixture waterproofing binder and her. 2.
