Application March 16, 1953, Serial No. 342,471

9 Claims. (Cl. 20-52) This invention relates to a sash and weather sealing construction for metallic windows particularly of the extruded aluminum type.

An object of the invention resides in the combination of a sash rail and weather sealing member that are so constructed and related that an effective weather seal will be provided throughout the length of the rail and which will be protected against distortion and the accumulation of foreign matter such as rain, snow or ice between the weather sealing member and the rail.

The matter of weather sealing windows, especially those of the type wherein there are relative sliding movements between the sash and the frame, would seem to be relatively simple but actually it is an ever existing problem as attested to by the numerous patents that have been granted on inventions directed to the solving of the problem. The problem exists because of the need to provide a tight seal between the sash and the frame which will be effective under all conditions of weather and all wind pressures and quick changes of pressures and yet will permit the easy operation of the sash in the frame.

The present invention, taking these two factors into consideration, provides an effective weather seal which is protected against inoperativeness under all weather conditions and which will permit the easy sliding of the sash from one position to another.

Further, the weather strip and rail are so intercon- 2' nected that the strip need not be secured to the rail by screws or other equivalent means, which results in a strip that while effectively connected to the rail has, nevertheless, a sliding, floating or adjusting movement on the rail.

With the above stated and other objects, such as will appear as the description herein progresses, the invention resides in the association of new and novel elements recited in the claims appended hereto.

In the drawing:

Figure l .is an elevation of a window, partly broken away, illustrating the position of the weather sealing members on horizontally slidable sashes,

Figure 2 is a section, enlarged, on line 2-2 of Figure l; and

Figure 3-is an enlarged view of a portion of a weather sealing member.

In the drawing the window frame is indicated by the reference character F and the sashes by the characters S and S-1, the sashes being horizontally slidable in the frame. The frame F, illustrated, is provided with

flanges

10 and 12 which, with the parting bead 14, provide

channels

16 and 18 for the reception of the sashes.

The upper and lower horizontal rails of the sashes slide in the

channels

16 and 18 of the header and of the sill of the frame as they are moved horizontally. The side rails of the sashes S and 8-1 enter and are withdrawn from the corresponding channels of the vertical side members of the window frame. Thus the weather sealing members are subjected to the action of different types ice of forces in normal window operations, one of the forces being developed by the sliding of the sashes in the

horizontal channels

16 and 18 and another by the entry into and withdrawal of the side rails of the sashes into and from the corresponding vertical channels of the frame.

The horizontal and vertical sash rails, one of which is indicated by the reference character R, are Preferably of extruded aluminum, and are adapted to enter into and slide within the

channels

16 and 18, between ribs 20 that extend the lengths of the frame members.

Each sash rail R is preferably substantially U-shaped in cross-section, comprising a base member 22 and side flanges 24 which are substantially coextensive.

Each of the flanges 24 is provided with depressed seats or grooves 26 that are substantially coextensive, longitudinally, with the sash rail.

The sash rails carry weather sealing members designated, generally, by reference character WS. Each of these members is trough-like in form and is generally U-shaped in cross-section, and is substantially coextensive longitudinally with the sash rail. These weather sealing members are, preferably, of stainless steel and are resilient.

The sealing members WS embrace the base 22 and the flanges 24 of the sash rail. The base 28 of the sealing member WS is secured, if desired, to the face of the sash rail R by suitable means, such as screws 30, adjacent the ends of the rail which screws may also be used to secure the rail ends together. When so secured the intermediate portion of the weather sealing member may be free so that upon movements of the sash it will adjust itself to the unevenness in the frame. The screws may, at times, be dispensed with. The side walls 32 of the members WS are joined to the base 28 by connector portions 34 that join the base 28 on lines spaced beyond and away from the rail R, as at 36. Because these connector portions 34 diverge or flare from the base 28 the side walls 32 are spaced from the sash rail member as shown at 38 in Figure 3.

The outer portions of the side Walls 32 converge, as at 40, and terminate in shoe members 42 that are forced into contact with the bases of the grooves 26 in the sash by the inherent resiliency of the sealing members. These shoe members 42 have their ends spaced from the end walls of the grooves at all times thus providing spaces 44 and 46 which will insure freedom of unhampered flexing of the sealing members WS and at the same time will insure that the shoe members will remain in surfaceto-surface contact with the bases of the grooves in the sash rails.

When the weather sealing members WS are in the position illustrated in the drawings the side walls 32 will be in forced contact with the ribs 20 on the frame F, the contact being the result of the resiliency of the weather sealing member and the fact that, normally, the distance between the ribs 20 is less than the distance between the outer faces of the walls 32. The compression of these walls toward each other will force the shoes 42 into surface-to-surface contact with the bases of the grooves 26.

When wind pressure is applied to the sash one of the walls 32 will have relative movement toward the face of the adjacent sash rail while the other wall 32 will move away from the face of the adjacent sash rail. The movement of the former will be possible because the shoe 42 is free to move in the groove 26 and the connector portion 34 tends to remain substantially parallel to the wall 32. Because of this action the wall 32 will maintain a surface-to-surface contact with the adjacent face of the rib 20 and the shoes 42 will tend to maintain surfaceto-surface contact with the walls of the grooves at 26.

The inclination of the connector members 34 facilitates the entry of the vertical rails of the sashes into the channels of the vertical frame members by a camming action, the length of the base member 28 being less than the distance between the opposed faces of the ribs 20.

While I have illustrated in Figure 2. the construction of the horizontal rails of a sash and the associated weather sealing member, it is to be understood that the vertical side rails of the sash may be of the same construction and each may carry a weather sealing member such as illustrated in Figure 2. Various details of the construction may be made without departing from the scope of the appended claims as will be obvious to one skilled in the art.
