:1] III ///I/ w INVENTOR TAEWDO/PE #4061? BY @lir, H0144} ATTORNEYS United States Patent 2,891,290 WINDOW SCUPPER ARRANGEMENT Theodore Hauck, Amityville, N.Y., assiguor to General Bronze Corporation, Garden City, N.Y. Application July 16, 1957, Serial No. 672,217
3 Claims. (Cl. 20-70) permit a continuous "draining regardless of wind pressure and yet will not permit the moisture to be blown back into the room.
Many attempts in this direction have been made by workersin the industry but these have met with indifferent'successg to make the weep holes small enough to resist the tendency of a back flow of the moisture under wind pressure and yet large enough for satisfactory drainage has posed a problem that has not been completely solved. l
The present invention, however, solves these problems and results in an improved scupper arrangement that is able continuously to drain the moisture from the sill even against great wind pressure but yet prevents the backing up of the moisture in the sill and possible overflowing into the room.
'In accordance with the present invention there is provided in the sill of a window a relatively large Weep hole opening which is covered by an outside flap. This flap freely swings over the weep hole to cover it against outside air blowing in but yet, while covering the weep hole, permits water -to drainout from the sill even against great wind pressure.
A better understanding of the invention together with a fuller appreciation of its many advantages will best be gained from the following description given in connection with the accompanying drawings wherein:
Figure 1 is a face view of a portion of a window sill fitted with a scupper arrangement according to the invention;
Figure 2 is a cross-sectional view taken as indicated by lines 2-2 in Figure 1;
Figure 3 is an enlarged cross-section of the scupper flap taken as indicated by lines 33 in Figure 1;
Figure 4 is is an exploded perspective view, somewhat enlarged, of the scupper flap and its mounting hinge plate; and
Figure 5 is a bottom view of the flap taken as indicated by lines 5-5 in Figure 2.
With reference particularly to Figures 1 and 2, there is shown a channeled window sill 12 which may be horizontally mounted on the lower edge of a window opening in a building (not shown). Hinged along a vertical line and mounted above the sill is a sash frame 14, which, as seen in Figure 2, is adapted to be swung outward, i.e., away from the sill when the Window is opened. When the Window is closed, frame 14 fits snugly against the sill as shown.
Because of the loose engagement of flap tongues 24 withincurved 28, the flap is in effect suspended on a floating hinge. This minimizes the likelihood of the flap binding in any position and makes the flap lie flush against plate 30 when closed and freely and quickly swinging even under extremely light pressures. It'will be appreciated that thestructure of this hinge and flap arrangement is very simple, moreover, a flap can be fitted over almost any weep hole in an already installed window. r l
When a gust of windi blowsagainst the outside bf thetwindow, flap 22 will swing closed over weep hole 16 in face to face contact with plate 30 and eifectively prevent rain and the like from being blown into the weep hole. To enable water or moisture to drain out from the sill when flap 22 is closed, the flap is provided with an outwardly bent center section 36. This section is bent with a taper across its width, as seen in Figure 5, and along its length, as seen in Figure 3. Thus, when the flap is closed there exists a thin tapered opening 38 between the inside face of flap section 36 and the lower portions of plate 30 and sill wall 18. Even with high winds blowing against the flap, water will still be able to drain through weep hole 16 and opening 38 to the outside.
The reason or reasons for this phenomenon are not fully understood but it may be due to capillary action of the water within tapered opening 38 or it may be due to a Venturi tube effect caused by the wind blowing past the mouth of this opening. In any event this scupper arrangement provides a very effective but inexpensive drain for a Window sill and the like. Liquid flow out from the sill will be allowed even against high winds and when there is no wind, i.e. when the flap is free to swing open, greater quantities of liquid and fairly large objects and debris can be flushed through the weep hole.
In a weep hole-flap arrangement, substantially identical to that illustrated herein, which has been built and successfully tested good water drainage through tapered ripening 738 "was obtained even in the face o'fwinds as high as 50 knots. The inside bottom edge of flap 22 along section 36 as seen in Figure was bent approximately inch out from the plane of the flap leaving a inch width for opening 38 at the bottom. Section -36aextended upwardfor approximately half the width of :the ffiap. This section was formed simply by bending -flap 22 outward along a vertical centerline by the -re- :quired amount. Chamfered face '21 was inclined .at 45 and extended down along the loweredge 'of-opening 32 in plate 30 as shown in Figure .2. The shapes and relative sizes and positions of the flap, weep hole and ,plate 30 were substantially exactly as shown herein.
The above description of the invention isintended in illustration and not in limitation thereof. Various achanges may occur to those skilled in the art and these may be made without departing from the spirit or scope rot-the. invention asset forth.
, This application is a'continua'tion impart of co pending :application, Serial No. 446,62-7, filed July '29, 1954, :Patent No. 2,'827,674,aissued March 25, 1958.
