noor rmsnme Original 110. 1300.010, dated Ianuary'29,'1929, Set! This invention relates to flashing sheets for use in the roofs of buildings, and has for its object the production of means for making a waterproof and permanent joint b etween adjacent parts of a roof,.as for instance the vertical face of a wall and an adjacent flat roof surface in what is thought to'be anunusually cheap and effective manner, by combining parts of special construction and arrangement hereinafter described. In the accompanying. drawings the preferred form of this invention is illustrated,

- and Fig.1 represents a wall in vertical section having this invention applied to'the wall .and shown likewise in vertical section. Fig.

2 is a vertical section of a portion of a. flashing sheet made in accor'd'ancezwith this invention in slightly modified arrangement,

and Fig: 3 is a fragmentary detail view show- 1 ing the aperture in the metal reinforce plate or sheet engaging the material of the flasheet to prevent displacement.

the same number is used to refer to the same Considering the drawings, Fig. 1 the bricks 1,- 2 aid 3 are laid as in any vertical wall, with mortar 4 between them. The flashing. sheet 5 made in accordance with this piece 7 which is also bent with the flashing sheet and the bent end is introduced: into the mortar 4. The flashing sheet 5 may be formed of asphalt, jpitch, tar or a-eombina tion of these or similar'plas'ticmaterials such as are used in roofing compositions and which can be made in anycolor and'in. units of 'any desired length or width. It will 3 be noted that the material of the flashing sheet in the mortar and designated by number 8 extends beyond the edge of the sheet 'metal .piece'fiand that it is solid to the end. .This

' construction is intended to prevent any mois-' ture reachiniethemetal piece 7, which may ndable sheet iron. It cannot rust and will give as long'service as more i 3 expensive metal. It is practicable to empl y v the ordinary sheet. iron of which stovepipes 1 are made, as it bends-freely without breakreissue filed June '4, 1930. Serial No. 458,283.

sh %hroughout"the drawings and description nvention has a bend 6 and a reinforce metal al No. 211,495, filed August 8, 1927. Application for observed that the sheet metal piece 7 is covered on' both faces by the material of the flashing sheet 5, and that the extension of that sheet beyond the edges of the piece '7 are made solid and of some extent. Those extended and solid portions of the material of the flashing sheet cannot split or separate and-no moisture can enter.

- As set out in Fig. 1 the downwardly extending portion of the flashing sheet 500vers the upwardly 'projectingportion .9 of the cat'ed correspondingly so that the rain can--; not splash or work-up between them. The- 'horizontal portion of the roofing is marked 10. It rests in the customary manner upon L the roof deck sheathingll carried by the joist 12 or like supports.

In Fig. 2 the construction of this invention is shown as slightly modified. The sheet composite roofing, or any other roofing .lo-

metal reinforce piece 13 is covered as before on both faces by the material of the flashing solidfor a distance beyond the edge of the sheet 13- as already explained. Under certain conditions it is desirable to prevent any 'considerable movement of the metal plate 13 and the'material of the flashing sheet 15,. whether this is caused by expansion and contraction or compression. The metal piece 13 and the plastic compositionof which the sheet 15, and the end 14; of that sheet is made V flashing sheetis mainly composed, do not I expand and. contract equally, and in order that the .plate may not be displaced with re.- spect tothe enclosing flashing sheet, or to a very limited extent, an aperture 16 may be 1 provided, or more than one aperture, through i L the mortar, and having an end or point19' pressed into engagement with-the material of the flashing sheet 5. The purpose of the clip or clips is to hold the bend end of the flashing in place in the mortar.

The operation of this invention is believed 5 to bemade clear by the drawings and the foregoing explanation. The metal reinforce pieces are located at the bends and reinforce the flashing at the external angles thereof. The metalpieces are "fully guarded against entering moisture, and are permanent. .By the use of this invention it is believed that flashing in roofs may be left for an almost unlimited time without any attention whatsoever.

While I have described my improved flashing sheet as applied to a joint between a vertical face wall and an adjacent fiat roof surface, it will be understood that such sheet may also be used in other roof structures where it is desired to provide a waterproofing strip having a permanently shaped reinforced angle margin but with a substantial portion of its area being of normal flexibility, both of which portions are adapted a to cooperate with adjacent parts of the roof 50 j or portion of the body being of normal flbxstructure as desired.

Having now described this invention and explained themode of using it, I claim I 1. A flashing sheet having a relatively wide 0 body adapted for vertical disposition in overlapping relation to adjacent roofing, an inwardly' extending attaching portion at the upper end of said body, a metallic plate of angular formation completely embedded in.

a the sheet adjacent the upper end thereof only and extending partly into saidbody and partly into said attaching portion, whereby the majorportion of the body is below said plate and is of normal flexibilty.

40 2. As an article of manufacture, a composite roofing strip of water roofing material having a relatively wide ody' adapted for overlapping relation to adjacent roofing, an angular extending portion along one edge of i said body, a metallic plate of angular formation completely embedded in the sheet at the angular extending portion only, and .extending partly into said body and partly into said angular extending portion, and the maibility below said plate.

3. As an article ofmanufacture, a com-' posite'roofing strip having a body of relatively flexible waterproofing material adapt- 5 ed for overlapping relation to adjacent roofing and having an angularly extending por-- tion along one edge of said body, a metallic late of angular formation completely embedded in said sheet at the angular extending portion onl a substantial portion of the body beyon said plate being of normal flex ibihty.
