Application April 17, 1937, Serial No. 137,425 8 Claims. (Cl. 108-—26) This invention relates to ?ashing for use at teeth engage the mortar or other material there the edges of roofs, corners or other parts of a about, thus preventing both longitudinal and lat building or other structure in order to prevent eral movement of the flashing. The degree of the entrance of moisture. curvature of the anchoring device should pref The use of metal ?ashings is well known. It is erably be such as to give a springing action to also known to use ?ashings consisting of fabrics assist in engaging the teeth. or a composition of fabric with metal. Metal While the anchoring device described above is ?ashings heretofore in use have suffered from the adapted to be used with an all-metal ?ashing, the disadvantage that they are di?icult to hold in preferred embodiment of the invention consists of a ?ashing formed from‘ a continuous metal 1.0 _. place. This is particularly true of metal ?ash ings adapted to be inserted into old walls, as dis sheet material having at one .end an anchoring tinguished from through-wall ?ashings in new device as described above and inserted into a buildings. Many of the fabric ?ashings hereto~ raggle or wall and joined outside of or along the fore provided are unsuitable because they wear wall to a water-repellent fabric material, prefer ably a bituminous coated ?brous material having 157 out too quickly. Thus, fabric ?ashings in which the fabric itself is imbedded into the wall tend a granular inert mineral surface, for example, a 15; to wear out and tear apart at the angle where slate-surfaced felt. These two materials are they enter the wall. In addition to the foregoing preferably joined in such a way that the water disadvantages, many ?ashings require auxiliary repellent ?brous material underlies a portion of 20: anchoring devices in order to hold them in place. the sheet metal so that said ?brous material is 2.0 The use of such devices is inconvenient and un not exposed at its upper edge and lies ?at along desirable. the wall. The joining of these two materials is It is an object of the present invention to pro preferably effected by means of pressed-in metal vide new and improved ?ashings which are read portions extending through slits in the fabric ily anchored in place either in new walls or in material, preferably transverse slits or cuts, in old walls and which do not involve the use of a direction away from the normal pull of the 25 auxiliary anchoring devices. A further object is fabric material. Thus, when the fabric mate the provision of a new and improved type of rial is hanging vertically, as would usually be the ?ashing consisting of a combination of two or case in a roo?ng construction, the pressed-in , more materials, one of which is a sheet metal, ' Another object is to provide a ?ashing consisting of a sheet metal joined to a fabric material in such a manner that only the metal is inserted into the raggle or wall and the fabric is joined v to the metal in such a way as to cause the mini 'mum amount of wear. An additional object is the provision of a ?ashing of the type just de scribed consisting of a combination of metal and fabric in which the fabric is a heavier type of 4:0 fabric than ordinarily used in ?ashings and is not adapted to be readily bent and inserted into a wall. A still further object is the provision of rial and upwardly and the two materials are 301 pressed or clamped together. Such a juncture between the two materials avoids the necessity of sharply bending the fabric material, which is practically impossible in the case of a very heavy material such as a slate-surfaced felt, and at the 35. same time it is unnecessary to employ auxiliary tying or fastening devices. Other features of the invention will become apparent from a reading of the following speci? cation in the light of the accompanying. drawing, a new and improved continuous metal-fabric in which Figure 1 is a side sectional view showing the ?ashing ‘in which the fabric is joined to the preferred type of ?ashing in place in a roo?ng metal without the aid of auxiliary tying or fas tening devices and without the necessity for bending the fabric. Other objects will appear construction; as the description proceeds. 50,‘ metal portions extend through the fabric mate . In accordance with the invention the new type of ?ashing herein described comprises a metal . Figure 2 is a front view of the preferred type 45 of ?ashing; Figure 3 is a side sectional view along'the line 3—-3v of Figure 2, with parts broken away; and Figure 4 is a front View of a modi?ed form of minating in a series of teeth. These teeth are cut from the metal, forming a continuation there of, and are preferably in the form of a continu ?ashing illustrating a different arrangement of 5.0 teeth in the anchoring portion. The ?ashing illustrated in Figures 1, 2 and 3 comprises a metal sheet material l0 having an end portion l2 angularly bent at an acute angle ous row of teeth, although they may be spaced at and terminating in a series of teeth I4. intervals. If desired, groups of two or more teeth shown, the sheetmetal material I0 is joined to a may be spaced at intervals. This end portion containing the teeth is preferably, although not necessarily, ‘curved in such a manner that the Water-repellent ?brous material It by means ‘of pressed-in metal portions l8,.20. The pressed-in sheet material, preferably copper, having an end portion angularly bent at an acute angle and ter As 55. metal portion l8 passes through a transverse slit 60 2 10 15 20 25 2,105,996 It will be understood that numerous variations or cut in the ?brous material at point 22, and is bent upwardly along the back of said material may be made without departing from the inven opposite the direction of pull. The metal and ?brous materials are preferably clamped tightly together in a manner such that the metal grips or bites into the ?ber, as illustrated, and forms a prising the turned up end portion l2 and teeth [4 may be applied to an all-metal ?ashing, e. g., unitary, composite structure with no substantial projections at the point of juncture. No auxil iary tying or fastening devices are required. In Figure 1, the composite ?ashing is shown in place in a roo?ng construction. As shown, the metal portion 24 is inserted into a raggle 2B, lying along the bottom thereof, with end portion l2 turned upwardly and curved from acute angle 28, whereby teeth l4v engage the top of raggle 26. After the ?ashing is in place, pressure gum caulk ing 30, mortar, a bituminous material or the like, is forced into raggle 26. The roof structure proper is subject to consid erable variation and the type of roof shown in the drawing is merely illustrative. As shown, the top of the roof deck or insulation 32 underlies composition roo?ng material 34, for example, a bituminous roo?ng composition. This latter, in turn, underlies a base ?ashing 36 which may be of any suitable construction ordinarily employed for this purpose. The ?brous portion I 6 of the unitary composite ?ashing is adapted to lie ver tically along the wall or base ?ashing, and pref 30 erably terminates at or near angle 38 in sheet metal portion In of the ?ashing. It will be ob served that no portion of the ?brous material I6 is bent and the upper end thereof underlies the metal portion of the composite ?ashing. This 35 arrangement avoids the disadvantages often found in fabric ?ashings which enter the Wall at or near the point 38, because such ?ashings tend to wear out at this point. Moreover, it is prac tically impossible with a fabric ?ashing which is bent at this point to employ a material there for such as slate-surfaced felt which is rela tively heavy and which tends to break when bent at a sharp angle. It is an important aspect of this invention to provide a composite, unitary, continuous ?ashing containing as one component thereof a bituminous coated ?brous material having a granular inert mineral surface, such, for example, as slate-surfaced felt. I In Figure 3 the springing action of the end 50 portion or anchoring device I2 is illustrated by the positions a, a’, the former showing the posi tion of the end portion l2 and the teeth l4 before, and the latter after, insertion into the raggle. The modi?ed form of ?ashing illustrated in Figure 4 is similar to the ?ashing shown in Fig ures 1, 2 and 3 except that the teeth 40 are not continuous throughout the entire width of the ?ashing. Otherwise the method of fastening the 60 metal to the ?brous portion of the ?ashing, shown 55 by the pressed-in portions 42, 44, is the same. The ?ashings shown in Figures 1, 2, 3 and 4 may be joined laterally in any suitable manner, for instance, by means of a soft copper joint 65 cover, not shown, overlapping the intersections between any two ?ashings and coextensive longi tudinally with both the metal portion and the fabric portion of the composite ?ashing. This metal joint cover may pass from the teeth I 4 70 along the intersection between two ?ashings and between the metal and fabric portions, ?nally being turned up on the back of the bottom of the fabric portion, for instance, at point 46. Any other suitable method of joining the ?ashings 75 together may be utilized. tion. For instance, the anchoring device com a single-piece copper ?ashing. As before stated, the end portion 12 need not be curved but may be straight, although a curvature in a direction away from the horizontal portion 24 is desirable in order to assist the springing action of the metal and the engagement of the teeth with the raggle. The dimensions of the ?ashing may ob— viously vary very widely, the distance of pene tration into the wall being determined by the position of the angle at point 38, which is pref 15 erably rounded. The means of fastening the ?brous sheet ma terial [6 to the metal sheet material In may be varied. For instance, the edge 20 does not nec essarily have to bite into the ?brous material, as shown, although it is desirable that the two materials, that is, the metal material and the ?brous material, be clamped together in such a way as to be relatively immovable with respect to each other. The horizontal slits 22 are pre 26 ferred, although if desired a vertical arrange ment may be employed. Vertical slits have a tendency to tear the fabric or other ?brous ma terial. , The metal sheet material may be copper, gal 80 vanized iron, brass, bronze, aluminum or other corrosion resistant metals. The ?brous material forming a part of the composite ?ashing may be a paper base, cloth, heavy felt, burlap or other ?brous fabric im pregnated or coated with a water-repellent ma terial, for example, asphalt, coal tar pitch or other bituminous substance. The preferred ma terial is a heavy felt impregnated with asphalt, coal tar pitch or the like and surfaced on the 40 wearing surface with granulated slate or other inert material, preferably a slate surfaced felt weighing from about 40 to 110 pounds, or more speci?cally about 90 pounds, per hundred square 45 feet. The ?ashing herein described can be inserted into any kind or size of raggle such as a raked , out brick joint of any size in an existing brick wall, a dry joint left in a new masonry wall for this purpose or a raggle cut into a new or exist 50 ing concrete or stone wall. The ?ashing can be built into a new wall if so desired. Ordinarily, the ?ashing is forced into the raggle with the aid of some wide ?at bladed instrument such as a thin bar or a wide ?at-edged chisel until it has 55 reached its proper position, then the raggle is ?lled with some plastic material such as a good caulking compound inserted by hand or prefer ably by the gun method. Before the ?ashing is in place it may be “spot mopped” if so desired, 60 or otherwise adhesively secured, at the bottom edge or at such intervals as may be thought nec essary to assist in making the bottom edge more secure and tight to the vertical surface. The composite unitary ?ashing herein de 65 scribed can be used to good advantage in any place in new or existing work where a ?ashing may be required, more easily and safely than other types of ?ashings now in use. It has all the advantages of metal ?ashings and is consid 70 erably less expensive. By virtue of the small surface of sheet metal exposed to the weather the expansion and contraction due to tempera ture changes is considerably less than that oo curring in an all sheet metal ?ashing, thereby 75 3 2,105,996 Cl avoiding the constant movement in the metal 2. A ?ashing comprising a metal sheet mate which causes all sheet metal ?ashings to work loose in the raggle and eventually leak or come rial having an end portion angularly bent at an acute angle and curved away from the metal, and terminating in a series of teeth. 3. A composite ?ashing comprising a continu out altogether. The anchoring device of my ?ashing elimi nates the necessity of wedges or other devices for locking the ?ashing into the wall. It also eliminates specially designed strips that are often built into the wall to receive ?ashings. All 10 that is required is a partially dry joint left in a brick or stone wall, a raked out joint in an ex isting brick or stone wall, a small ?llet strip placed in the forms for a. new concrete wall or a small, comparatively shallow, raggle cut into an existing concrete wall. Where the ?ashing is forced into the raggle the curved portion con taining the teeth is pressed downward at the top surface of the raggle. Once the teeth have passed the top outside edge of the raggle the 20 springing action of the curved metal forces the teeth up against the top surface of the raggle where they engage themselves into any pores or other irregularities of the surface and resist any effort to pull the ?ashing out of the raggle. W'hile resisting any outward movement of the ?ashing, the arrangement of the teeth is such as to permit the very slight sidewise movement that may be necessary to accommodate the very slight movement due to expansion and contrac 30 tion. Where special metals are used for decorating purposes and a ?ashing is required, the felt or fabric can be omitted and the ?ashing made of the same decorative metals even to the extent of forming a part of the design. The self locking feature of the ?ashing reduces installation labor costs greatly. Furthermore, it can be installed very quickly. Certain fabric ?ashings are on the market and 40 their weakness has been proven to be along the point at which they enter into the wall. The bituminous substance wears out or evaporates along this line leaving only the base material which will not exclude water and may become 45 rotten or torn. The preferred type of ?ashing of the present invention has metal along this line which will endure for the’life of the metal, resist water and stand any reasonable amount of me chanical abuse. The manner in which the ?brous material is attached to the sheet metal permits the felt or fabric to- ?t tightly against the wall or base ?ash ings. Also ?ashings can be carried to a point much higher than is usual above horizontal sur 55 faces with but very slight additional expense be cause of the cheapness of the felt or fabric which forms the vertical surface as compared to metal. The shape of the ?ashing is such that it will “nes ” well for economical shipment and can be 60 factory made in standard lengths and easily crated. Corners and laps can be quickly and easily made with four inch wide strips of plain sheet metal and aside from the insertion of the ?ashing in the raggles, this is the only ?eldwork 65 necessary to make a complete, permanently wa~ tertight installation. Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is: 1.
