FLASHING.

Application led January 26, 1922. Serial No. 531,847. I

To all 'whom 'it may concer/n.'

Be it known that I, CARROLL C. Fleer., a citizen of the United States, residing at Chicago, in the county of Cook and State of Ilhnois, have invented certain new and useful Improvements in Flashing, of which the following is a specification.

This invention relates to a hashing for use at the edges of roofs, decks, hoors, and

the like, and the principal object of the in vention is to provide a construction which has a greater tensile strength than the hashings, other than those of metal, in use at the present time, and having a greater life than the hashings commonly used either when made of metal or other material, as commonly employed. Another object of the invention is to provide a hashing which is heldsecurely in place in a raggle joint and tends to become more firmly wedged therein if a tension is applied to the hashing proper. Another obj ect of the invention is to provide a hashing' of this kind in strip form With a continuous or-sectional metal holding 'clip so that the hashing can be easily applied and secured in place. Other objects will appear hereinafter.

In the accompanying drawings, Fig. l 'is a plan view of ahashing constructed in accordance with the principles of -this invention and applied to the edge of a roof; Fig.- 2 is a section taken on the line '2 2 of Fig. 1; Fig. 3 is a section taken on the line 3 3 of Fig. l; Fig. 4 illustrates a hashing with a pair of holding plates and a plurality of' hashing strips; Fig. 5 illustrates a modihed form of hashing in place; Fig. 5 is' an enlarged view of a portion of the modihed form of hashing shown in Fig. 5; Fig. 6 isa section taken on the line 6-6 of Fig. 3; Fig. 7 illustrates a metal strip of diherent form; 'and Fig. 8 shows this strip applied to a wood base board.

It is the present practice to make a hashin either of metal in one or two pieces w ich quickly deteriorates dueto the exposed position and the action of the elements, or to use a felt paper or, fabric impregnated with bitumen, which has very little tensile strength, which may be somewhat brittle and will readily break. The present invention proposes a-hashing which is made up of a fabric of considerable tensile strength, usually in several layers and attached to a metal clip `by Which it is readily and firmly Another feature ings, this hashing is applied to a brick Wall l of ordinary construction which extends above or at the side ofa roof or deck 2. The dihiculty is to make a huid-tight joint in the angular corner between the roof and the brick wall. The roof itself has a covering 3 which extends up to the ed e of the wall, and this covering may be o any desired or suitable construction, usually consisting of asphalt roofing, of various kinds, in suhicient thickness to form a thoroughly waterproof covering.

The hashing of the present invention comprises a plurality of strips 4 and 5 of Woven material such as canvass or the like, which has considerable tensile strength and is also of such a character that it will become saturated with and hold a quantity of coating of bitumen such as tar or 'asphalt paint. These strips .of material are secured together along their corresponding edges and to a clip 6 preferably composed of a metal bend in the form of a V with the edges thereof curving slightly outward, the impregnated strips 4 and 5 being secured thereto by metal tongues 7 bent outwardlyfrom the strip 6 and through the strips 4 and 5 securing them in place against the metal strip 6. f

Instead of having a continuous metal strip 6, there may bea plurality of sectional strips of this kind at intervals, as indicated in Fig. l, and of course the hashing will be supplied in lengths which will overlap at their extremities to make a huid-tight' joint.

Instead of having one metalv strip 6, the 10 fabric strips'may be secured together by a pair of metal strips 8 and 9 connected by rivets 10, as shown inV Fig. 4, and the hashing proper may consist of outer woven fabrics 4 and 5 with an inner layer 11 of a 105 more yielding material, such as a felt material, either paper or fabric'. To further strengthen either of the fabrics 4 or 5 a ynet work or screen l2 of woven wire fabric may be incorporated in the strip or as a part/of the hashing.

In applying a hashing of this kind a raggle is made between two adjacent courses of brick at a slight height above the surface of they floor 2, the connected edges of the flashing strips including the metal strip 6 are inserted in the raggle' with the strips lying at the bottom thereof, and a cement 13 fills up the joint made by the raggle between' the bricks. The width of the metal strip is such that its edges preferably engage the adjacent brick courses, and it may be slightly compressed to insert it in the raggle, the object being that if any attempt is made to pull it by means of the strips 4 or 5, the opposite edge of the strip 6 will be pressed against the brick surface tending to hold it in. Thus the flashing would beheld in place without the cement 13 by the resiliency of the strips, but the cement is also included and acts as an anchor as well as a preservative.l

- The depending portions of the strips 4 andv lie against the wall and may be secured to each other and to it by an asphalt paint, the lower ends of these fabric strips preferably overlap so that the inner one is attached to the edge of the roof covering 3, as lshown in Fig. 2, and the outer one is secured to the lower fabric strip 5, overlaps it and its overlapping edge is also Secured to the covering 3.

As shown in Fig. 5, the under layer of fabric extends below the edge of the covering 3, while the outer fabric layer 4 extends on top of the covering. Tn the flashing shown in this figure the layer 11 also overlaps the covering 3, and the connected edges of the flashing fabrics are secured together by stitches 14 of wire or metal clips. Thus it is possible to disperse with the spring strips 6 if a holding cement 13 is employed but the metal strip construction is preferable.

This flashing when constructed of two or more plies of fab-ric, secured in a raggle point With the self-locking spring clip and the raggle then filled with an asphalt cement, will be more lasting than an all metal flashing and will be considerably less expensive. The fabric has a high tensile strength with the property of withstanding abuse of a marked degree, and when impregnated with its own weight, or more, of a bitumen, will last indefinitely if properly applied. lVlien this flashing is properly applied water runs over the lap or crevice and not into it. Even if the cement 13 be. comes loose the flashin will remain in place and will be water-tight. Owing to the tou hneSs of the fabric, protection is affor ed to that section of the roofing which constitutes fthe bend from the deck to the wall. It is at this point vthat good roofs frequently leak owing to the use of inferior flashings.

The way the flashing lies, in the raggle depends upon how it is gouged out and the metal strip can be bent as desired to fit the raggle. The metal strip 6 may have one flat edge 15, as shown by Fig. 7, which lies parallel with the lower course of brick and with the other or outer edge bent or rounded upwardly therefrom` the extremity 16 of the outer edge being bent sharply outward so that it will engage the course of brick at the top of the raggle. The holding cement 13 is inserted in the outer edge of the raggle to hold the flashing in place `as before and any outward pull upon the fabric tends to engage the bent edge 16 with the upper course of brick thereby binding the flashing more securely in position.

The form of flashing shown in 7 is particularly adaptable for use in connection with roof constructions where there is a wooden base board as well as a brick wall in which the flashing is to be inserted. As shown by Fig. 8 the metal. strip 6 is bent substantially at right angles and the bent edge 16 of the metal strip is driven into a. base board 1T -by a ,fastening device 18 which holds it securely in place and, makes a joint with a base board resembling a raggle in which there is no opportunity for any moisture to get beyond the flashing. It should be understood that in applying flashing of this kind the fabric strips are usually loose from each other before the flashing is applied, but they may be secured to each other, to the wall or to the roof deck, usually by means of a hot swabbing of bitumen paint or the like, which holds the fabrics together and makes, them additionally water proof. lt is obvious that the metal strips ma be furnished flat and bent to any desired s ape corresponding to the placewhere the flashing is to be applied.
