WINDOW SILL CONSTRUCTION Filed March 16, 1953 INVENTOR Tkeoclore jfau/ck/ M M 13y ATTO 5 5' s United States PatentO WINDOW SILL CDNSTRUCTIGN Theodore Hauck, Bellmore, N. Y., assignor to General Bronze CorporatiomGarden City, N. Y.

Application March 16, 1953, Serial No. 342,472

12 Claims. 01. 20-70 are mounted, although the invention has other applicat tions as will be realized from the following description.

In sills of the type referred to, moisture collects in both the inner and outer channels and must be led to the outside and there discharged to prevent suflicient accumulation in the inner channel to cause an overflow into the room in which the window is installed. It will be realized that outside pressure such as created by a wind will tend to prevent the discharge of the moisture and to cause it to accumulate in the channels.

To provide for a discharge of the moisture from the channels against the effect of the outside pressure, each independently of the other, the invention contemplates a direct discharge of the moisture from the outer channel to the outside and in addition a direct discharge of the moisture from the inner channel to the outside.

In the drawing I have illustrated the invention as being applied to the sill of an extruded window frame in which horizontally slidable sashes are mounted.

In these drawings,

Figure 1 is a fragmentary-elevation illustrating the type of scupper that is incorporated in the sill for the discharge of the moisture from the outer channel.

Figure 2 is an enlarged transverse vertical sectional view on line 22 of Figure 1. 1

Figure 3 is a fragmentary elevation of the sill illustrating the type of scupper that is incorporated therein for discharging the moisture from an inner horizontal channel of the frame.

Figure 4 is a vertical section on line 4-4 of Figure 3; and

Figure 5 is a horizontal section on line 55 of Figure 3.

In the drawing, reference character the sill is indicated generally by the S. The outer horizontal channel in the sill is indicated by the reference character OC, while the adjacent inner channel is indicated by the reference character IC. These channels are formed by an outer flange F, an inner flange F1 and an intermediate flange or partingstrip F2 which extend upwardly from the base B of the sill. The upper edges of these flanges are provided with bearing members between which the sashes slidably move to close or open the window frame opening.

To permit the water to drain from the outer channel, scuppers, indicated generally by the reference numeral 10, are provided at as many locations along the length of the sill as are desirable in a sill of a particular length. Each of these scuppers comprises an opening 12 which is baflled by louver 14, the louver being formed by striking out a portion of the flange F to such an extent that the mouth of the opening 12 will discharge downwardly and the opening 12 will otherwise be substantially covered bythe louver. i p

A moisture discharge surface 16 inclines downwardly and outwardly, as shown in Figure 2, substantially from the plane of the inner facelS of the flange F and from the junction 20 of the inner surface 22 of the channel DC with the inner face 18 of the flange F. Moreover the inner surface 24 of the louver 14 extends downwardly and outwardly from the inner face 18 of the flange F to the discharge opening 12.

When water accumulates in the channel 0C it will flow to one or more of the scuppers 10 and through the scuppers to the outside of the building.

The dimensions of the opening at 12 are such that the accumulated water in the channel 00 will create a bridge or darn across the opening 12 due to the restraining influence resulting from the surface tension of the water at this point. However, when the water builds up a suflicient head the restraining effect of the surface tension will be overcome and the water will start to flow. This flow is greatly facilitated by the inclined moisture discharge surface 16.

With a scupper of this form it is possible to incorporate in a sill, scuppers of relatively small size without seriously affecting the flow of the moisture therefrom.

While the dimensions of the opening 12 through the face 18 of the outer flange F are not critical, I have found that there are certain optimum measurements which have produced satisfactory results in tests. I have found that the distance between the

surfaces

16 and 24 should be not substantially greater than three nor less than one eighth of an inch. I have found a scupper of one inch in length to be satisfactory.

To permit the discharge of moisture from the inner channel IC, unhampered bythe effect of any wind pressure to which the scuppers 10 are subjected, I provide the inner channel IC with scuppers of the form illustrated in the drawings. By means of these scuppers the moisture is conducted from the inner channel IC directly to the outside without being commingled with the moisture that accumulates in the outer channel 0C.

The outer flange F (Figure 4) ing 26 and the parting bead opening 28, which openings 26 and 28 are in substantial alignment with each other to establish a direct passage between the outside and the inside channel IC.

To provide for the passage of moisture from the inner channel IC to the outside in isolation from the outer channel 0C but traversing the same, I have provided a discharge conduit, illustrated in Figures 3, 4 and 5. This conduit comprises

side Walls

30 and 32 and an upper wall 34 which form a conduit having open ends of substantially the same shape and dimensions as the

openings

26 and 28 in the. flanges F and F2 respectively.

F2 is provided with an The inner ends of the

side walls

30 and 32 are bent as i at 36 around the inner face of the flange F2 to secure the conduit in position against outward movement.

A closure flap 38 is provided for opening and closing the passage through the conduit. In the form illustrated in the drawing, the outer end of the upper wall 34 of the conduit extends beyond the outer face of the flange F to provide a support for the closure flap 38. This portion of the upper wall 34 is rolled, as at 40, to form the support referred to. The closure flap 38 is provided with a recess 42 for receiving the rolled portion 49 as illustrated in Figure 3. This recess 42 results in the formation of cars or ear portions 44 between which trunnions 46 extend. These trunnions are mounted within the rolled portion 40 of the flap support in such manner that the closure flap 38 may have free inward and outward pivotal movements, the freedom being permitted because of the fact that the space in the rolled portion siXteenths of an inch is provided with an open- 4Q somewhat larger than the cross-section of .the.trun-. nions.

The ear portions 44 are bent outwardly to permit the closure-flapfto v engage "the outer-face of the flan'g'e' and to abut this face when the flap reaches the desired open position;

The upw'ardly' 1011a: portion 40 of the flap suppdrfl effectively closes -ari'y space that: exists"-'be'tween 'the 'uppeii face, ofthe wall 34and the adjacent "face of the opening at '26: v
