Application filed. August 8,1927. ISeriaI N0.-21'1,495.

This invention relates to flashing sheets i for use in the roofs of buildings, and has for its object the production of means for making a waterproof and permanent joint between the vertical face of a wall and an ad-' jacent flat roof surface in what is thought to be an unusually cheap and effective manner, by combining parts of special construc- 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 2 is a vertical section of a portion of a flashing sheet made in accordance with this in vention in slightly modified arrangement,

V ture'reaching the meta] piece 7, which mayand Fig. 3 is a fragmentary detail view showing the aperture in the metal reinforce plate or sheet engaging the material of the flashing sheet. to prevent displacement.

Throughout the drawings and description the same number is used to refer to the same part. 7 p

Considering the drawings, Fig. 1, the bricks 1, 2 and 3 are laid as in any vertical wall, with mortar 4 between them. The flashing sheet 5 made in accordance with this invention has a bend 6 and a reinforce metal piece 7 which is also bent with the flashing sheet and the bent end is introducedinto the mortar 4E. The flashing sheet 5 .may be formed of asphalt, pitch, tar or a combination of these or similar plastic materials such as are used in roofing compositions and which can be made in any color and in units of any desired length or width. It will 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 7 and that it is solid to the end. This construction is intended to prevent any moisbe of cheap bendable sheet iron. It cannot rust and will give as long service as more expensive metal. It is practicable to employ the ordinary sheet iron of which stove pipes v are made, as it bends freely without breaking and ischeap. In Fig. 1 it will be furtherobserved 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. solid portions of the material of the flashing Those extended and sheet cannot split or separate and no moisture can enter.

As set out in Fig. 1 the downwardly extending portionof the flashing sheet 5 covers the upwardly projecting portion 9 of the composite roofing, or any other roofing located correspondingly, so that the rain cannot splash or work up'between them. The horizontal portion of the roofing is markedlO. It rests in the customary manner upon the roofdeck sheathing 11 carried by the joist 12 or like supports. I

InFig. 2 the construction of this invention is shown as slightly modified. The sheet metal reinforce piece 13 is covered as before on both faces by the material of the flashing sheet 15, and the end 14 of that sheet is made solid for 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 v15,

whether this is caused by expansion and contraction or compression. The metal piece 13 and the plasticcomposition of which the flashing'sheet is mainly composed, do not The construction is also shown in Fig. 3.

The portion referred to by number 17 in Fig. 2 is a cap or counter flashing of any material applied to the flashing sheet 15 eX- ternally.

Again consldering Fig. 1,'there willfbe noted one of the wire clips 18. embedded in the mortar 4, and having an end or point 19 pressed into engagement with the material 2 of the flashing sheet 5. The purpose of the clip or clips is to hold the bent end ofthe flashing in place in the mortar. A I Theoperation of this invention is believed to be made 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 metal pieces 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 upper end of said body, a metallic plate of 10 unlimited time without any attention what angular formation completely embedded in soever. the sheet adjacent the upper end thereof only Having now described this invention and and extending partly into said body i and 5 explained the mode of using it, I claim :f partly into said attaching portion, whereby A flashing sheet having a'relatively wide the major portion of the body is below said 15 body adapted for vertical disposition in plateand is of normal flexibility.
