Patented Mar. 11, 1952 x .UNITED s'm'rlizs..v PATENT OFFICE 2,588,697 ,y WEATHRSTRP FOR CAS-EM'T WINDOWS Donald J Burch, Denver, Colo. Application July 9, 1951, serial No. 235,"726' s' claims; (C1. 1-so- -40) 1 This invention relates to improvements in metal easement Windows and relates more particularly to a weather strip therefore.
Metal Casement windows are constructed from steel orv aluminum bars of various crossesectional shapes. When aluminum is used, the frame membersare, in most cases, extruded through vdies and, as a result, have surfaces that are quite straight and' smooth.
It has" been found that metal easement windows will allow both air and fine dust to pass unless some form of' seal or weatherstrip is employed'.
A large number of weatherstrip means have been proposed and several have been patented.
the invention has been illustrated and in which:
Figure 1 is a front elevational View of a conventional window frame and sash, showing the invention applied thereto;
Figure 2 is a section taken on line 2 2, Figure 1;
Figure 3 is a cross section taken on line 3 3, Figure 1;
Figure 4 is a section, similar to the one shown in Figure 3, and shows a modined form of construction;
Figure 5 is a view partly in perspective and partly in section, taken on line 5 5, Figure 1, and
Figure 6 is a section through the screen frame showing the resilient compressible seal strip in place thereon.
In the drawing reference I0 designates a building wall to which the window frame is attached. For the purpose of this description, the window frame has been shown as formed from a member having, what may be loosely dened, as a Z-shape cross section and which, as shown in the several sections, consists of a web II from opposite edges of which flanges I2 and I3 extend in parallel The sash frame has been shown as formed from a similarly shaped member having a web IIa and oppositely extending flanges I2a and I 3a. For the purpose of this explanation,
the frame members and the sash members may be identical in size and shape.
Flange I3 of the window frame is usually embedded in the window wall, as indicated in`F'igure 2'. 'Ihewindow sash has been shown as attached to the frame by a hinge Whose pivot has been designated by I 4. If the window is wide, it is usually formed in two sections separated by a mullion I5.
In the further description, the construction shown in Figures 2 to.V 6 willbe considered;
The" frame and sash members are so related as to size that when the inner surface of ange I3a contacts the outside surface of flange I3, the outer surface of flange 12a will contact the inner surface of iiange I2. For various reasons, the double closure formed by the two pairs of flanges will not prevent an apprecablequantity of air 'and dust from passing. `.en additional seal is therefore desirable and will now be described.
In most cases where easement windows are used, theywope'n outwardly or upwardly when Viewed in Figure l2 and the wire screens IB are therefore applied to the inside of the window frame'. The w'idow sash is, of course, glazed and vthe glass pane= has been designated by numeral H'. The pane is secured to the sash inthe usual manner and is held in place by putty I8.
The wire screen is secured in metal frame I9 oi elongated U-shaped cross section, as shown in the several views. The screen edges are secured in the frame by means of splines 2), in a wellknown manner. Such screens are held in place by clips of various shapes that are secured by screws. In the drawing, the holding clips have been shown as broadly U-shape with one stem or side shorter than the other. Referring now more particularly to Figure 3 where the shape of the clip is most clearly shown, the long side has been designated by 2l and the shorter side by 22, the securing screw is designated by 23. Side 2l rests on the outer surface of screen frame member I9 and urges it towards the outer surface of ange I2.
The air and dust leakage takes place between the adjacent surfaces of flanges I2 and IZa, and it is the object of this invention to form a resilient seal that will prevent air and/ or dust from passing at the point indicated.
In Figure 6, frame member I9 and the seal strip have been shown to a somewhat larger scale than in the other gures, and in this view, which is a cross section, the seal strip 24 has been shown as attached to the under surface of frame I9 and extends the entire length thereof. One edge of the seal strip is provided with a rib 25 that normally extends to a point beyond the inner surface of flange l2. The seal strip may be attached to the frame member by means of a suitable adhesive, or it may be vulcanized to the frame member, or it may be attached to it by screws 26 which may also serve to secure the screen in the frame. The seal strip is provided with grooves 21 for the heads of the screws and to provide narrow ridges 28 that can be readily compressed.
It will be observed that the seal strip has a width substantially the same as the width of member I9 and that the latter is so positioned that the ridge 25 will be beyond the edge of flange l2, and it will therefore contact the outer surface of ange l2a and be slightly deformed by the latter when the sash is in closed position.
Since the seal strip is permanently attached to one side of screen frame I9, and since the latter is of such size relative to flange I2 that rib 25 will rest entirely on the surface ofrange 12a, it will be in operative position whenever the screen frame is in position.
The seal strip may be made from any suitable material such as natural or synthetic rubber or plastic and must be resilient so that when the rib is compressed by the sash, it will conform to any and all irregularities and form a tight seal. Since the differencein air pressure on opposite sides of the seal is small, the seal may be readily compressible and may therefore be made, in part at least, from sponge rubber or very soft rubber or plastic.
Having described the invention what is claimed as new :ls:
l. A combined window screen and air and dust seal for use with metal easement windows, comprising, a screen frame of elongated U-shape cross section arranged with the opening facing inwardly to receive the edges of a wire screen, and a resilient dust-seal strip secured to the inner surface of the said screen frame, the inner edge of the seal strip having a laterally projecting rib forming a deformable seal member.
2. A combined window screen and air and dust seal for use on metal easement windows of the type having a window frame with an inwardly extending ange and a sash frame provided with a ilat surface for engagement with one side of the ange when the sash is in closed position, said surface extending inwardly beyond the edge of the ange forming a ledge, the screen frame having one side provided with a seal strip adapted to be positioned between it and the flange, the seal strip having the side facing said flange provided with a rib extending laterally along one edge of the flange, the rib being normally thicker than the flange wherefore it will project beyond the opposite side of the flange to a position to be engaged by the flat surface of the sash when the latter is in closed position, and means comprising screws for securing the screen frame and the seal strip to the ange.
3. In a metal easement window having a frame provided with an inwardly extending ange. and a sash frame having a fiat surface for engagement with one side of the flange when the sash is in closed position; means for effecting an air and dust-tightseal between the two framemembers, said means comprising a seal strip lof resilient rubber-like material positioned against the opposite surface of the flange from that facing the sash frame, the latter extending inwardly beyond the edge of the flange, the seal strip having a rib projecting laterally from one side along one edge, the rib being thicker than the ange wherefore it will be engaged by the flat surface of the sash frame when the latter is in closed position, and means for securing the seal strip to the flange, comprising a metal frame of substantially the same width as the strip pcsitioned against its outer surface and means comprising screws for attaching the last-named frame to the flange and holding it from movement in response to the force exerted thereon by the sash frame when in closed position.
