WILLIAM L. HAHLEY, 0F NQPJTZPI LITTLE BUCK, ARKANSAS.
Application filed. October 1,
To aZZ 1127mm it may concern:
Be it known that I, WILLIAM L. l-lAwLnY, a citizen of the United States, and a resi dent of the city of North Little Rock, in the county of Pulaski and State of Arkansas, have invented anew and Improved lValL Flashing, of which the following is a full, clear, and exact description.
This invention relates to improvements in wall flashings, an object of the invention being to provide a construction of wall flashing which will prevent possibility of leaking at the joint covered by the flashing.
A further object is to provide a wall flashing especially designed for reinforced con crete building structures and which can be anchored in the wall as the latter is built and which will be comparatively cheap to install and most efficient in the performance of its functions.
lVith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawings:
Figure 1 is a view in section showing a wall in course of construction.
Fig. 2 is a view in section on the line 2-2 of Fig. 1 showing the flashing complete.
Fig. 3 is an enlarged view in vertical section illustrating the flashing. 1
Fig. 4 is a fragmentary perspective view of the flashing strip.
1 represents a fragment of roof and 2 a wall joining the same both of reinforced concrete.
As the wall 2 is molded between forms 3, a waterproof metal flashing strip 4 is embedded therein. This strip is provided with bolts 5, having anchoring ends 6 embedded in the concrete and every third bolt, or any number of said bolts are sufficiently long to project through the form 3 and are secured by nuts 7 to securely hold the flashing strip while forming the wall. These long bolts are cut off when the form is removed.
The bolts 5 are projected through spring metal strips 8 which are bowed transversely and adapted to securely clamp any number of sheets of waterproof material 9 which extend across the joint 10 of the wall and ceiling.
Specification of Letters Patent.
1919. Serial No. 327,628.
The flashing strip is of the shape shown in cross section in Figs. 1, 2 and 4t, and is bent on a lon itudinal line at a sharp angle as shown at 11 forming a lip 12 which extends to the edge of the wall and positions the main portion of the strip at an angle, to provide a recess in the wall.
The lower edge of the strip is bent at an angle and corrugated or otherwise shaped as shown at 13 to form a secure anchorage in the wall.
The sheets 9 are positioned between the strip i and spring strip 8 with their edges in the angle 11 and when the nuts 7 are screwed down they will be securely held.
The roofing may of course be finished in any desired manner.
The metal strips l and 8 are preferably of steel suitably treated to make them rust proof but I of course do not limit myself to any particular material.
The bolts 5 have their inner ends bent at an angle to form the anchoring ends 6 embedded in the concrete and they may of course be otherwise shaped if desired.
Various slight changes might be made in the general form of the parts described without departing from my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.
1. The combination with a vertical wall, and a roof, of a flashing strip comprising a plate inclined vertically with its lower edge flushwith the face of the wall and having an integral anchoring strip at its lower edge and an integral flange at its upper edge projecting to the surface of the wall, waterproof sheets located against the plate and extending upwardly against said last-mentioned strip, and a spring clamping strip having its edges located against the water proof sheets, bolts projected through the flashing strip and through said clamping strip, and nuts on the bolts for clamping said waterproof sheets against the flashing strip.
2. The combination with a vertical wall, and a roof, of a flashing strip embedded in the vertical wall, said flashing strip comprising a plate inclined vertically with its lower edge flush with the face of the wall, said plate having an integral flange at its upper edge projecting to the surface of the Wall and having an integral anchoring strip at its lower edge embedded in the wall, Water- 5 proof sheets located against the plate, a
spring clamping strip having its edges located against the Waterproof sheets, bolts anchored in the Wall and projecting through the plate of the flashing strip, through the Waterproof sheets and the clamping strip, 10 and nuts on the outer ends of the bolts against the clamping strip.
