Application July 29, 1954, Serial No. 446,627

2 Claims. (Cl. Ztl-70) This invention relates to a scupper for the sill of a window.

An object of the inventionresides in the provision of a A further object of the invention is to provide sucha of the sill by fasteners such as screws 28, or, as disclosed in the modified form of the invention, it may be securedV in position by tongues which are preferably struck from the material of the plate to extend through the weep hole and engage the edge 32 thereof with suicient irm ness to maintain the plate in position on the sill. This engagement is assisted by the inherent resiliency of the metal.

This plate 24 is provided with a bearing member 34 which, preferably, is struck from the material of lthe plate during the formation of the opening 26 and is bent intocurved form such as that shown in Figure 7 of the drawing.

A ap 36 of suicient size to close the opening 26, is provided with a p air of trunnions 38 which extend into the ends of the bearing member 34 freely to permit the plate to swing from a vertical closed position outwardly to a suicient extent to permit the ow of moisture from the sash channel 14 through the weep holes 22 and through the opening 26. There is a loose pivotal relation- *Y ship between the trunnions 38A and the bearing member.'

s'c'uppe'r as will make it possible to enlarge theconviitional weep holes that are used to the end that the moisture freely may ow therefrom.

A further object of the invention resides in the provision of such a scupper as readily may be installed on the sill after the window has been emplaced in the building.

The invention resides in the combination and relation of parts herein described, disclosed in the drawing and recited in the claims.

In the drawing,

Figure l is a face view of a portion of a sill and of an embodiment of the scupper of this invention,

Figure 2 is a vertical section on line 2 2 of Figure l,

Figure 3 is a vertical section on line 3 3 of Figure l,

Figure 4 is a face view of a portion of a sill disclosing a modified form of scupper,

Figure 5 is a vertical sectional view on line 5-5 of Figure 4,

Figure 6 is a fragmentary sectional view on line 6-6 of Figure 4; and

Figure 7 is an exploded perspective view of the two parts of the scupper illustrated in Figure 1 of the drawing.

In many types of metal Windows where there is an upwardly opening channel in the sill, it is the practice to provide an outer flange of the sill with weep holes which are intended to permit moisture to drain from the channel through the face of the sill. However, these weep holes are made usually relatively small in an attempt to prevent the wind pressure from backing the moisture up in the channel.

When they are enlarged, While they will permit a freer flow of moisture from the channel, they will also greatly increase the electiveness of the wind pressure in backing the moisture up in the channel.

In order to overcome this disadvantage and to provide for the continuous ow of the moisture from the outer channel, I propose to provide enlarged weep holes and I have disclosed in the drawing such an enlarged weep hole at 22. There may be several of these Weep holes along the length of the face of the sill. These Weep holes may be provided after a window has been installed by enlarging the original weep holes.

To insure the continuous ow of the moisture from the sill channel and to odset the etect of the wind pressure,"

I provide a scupper which comprises essentially a plate 24 which is secured to the outer face of the sill and is provided with an opening 26 of substantially the size of the weep hole 22 and which is in registration with the weep hole. This plate 24 may be secured to the outer face 34 because :of thefsmallersize of-the -trunnions. This' permits the trunnions freely to move to the lower position of this bearing member under the inuence of the weight of the flap. This insures the proper automatic positioning of the ap.

In order to limit the outward movement of the ap 36 a pair of ears 40 is provided. These ears extend upwardly beyond the ttunnious 38 and outwardly in an inclined relation in respect of the outer surface of the ilap 36. They serve to contact the plate 24 adjacent its upper edge to limit the outward movement of the flap, and because of the fact that they extend outwardly beyond the outer face of the flap 36 and are located above the pivot line of the trunnions 38, they tend to maintain the flap in a vertical -or closed position against the plate 24.

While the plate 24 may be made of various materials, aluminum and its alloys are particularly adapted for use. Moreover the ap 36 is made of relatively thin gauge and light metallic material, such as aluminum or its alloys so that it will offer the minimum resistance of the ow of moisture from the sill channel.

It is obvious that when wind pressure is applied to the face of the ap 36 it will close the ap against the opening 26 in the plate 24. This will prevent the wind pressure from backing up the moisture in the sill channel.

However, when the wind pressure is relieved the weight of the moisture will be sufficient to open the ap and permit the moisture to either ow through the weep hole 22 to the outside or to trickle therethrough depending upon the amount of moisture and the head of the liquid.

While I have described the embodiment of the invention in connection with a sliding window having sashes in inner and outer channels, the invention is not limited to such a window as it may be used in connection with a sill having a channel of any form and having sashes of any of the many types.

What I claim is:
