Application August 14, 1946, Serial No. 690,502

the methods for extruding aluminum to any desired shape has become popular, such windows have increased in popularity, due to the fact that the window sash and window frame constructed in accordance with the latest methods, are highly ernamental and are of such uniform construction that the windows constructed with them are highly satisfactory.

With the ordinary casement window, the window sash containing the glass is hinged so as to teen and close like an ordinary door.

It is an object of this invention to produce a window sash and a window frame construction that, in addition to being of a very neat appearance and containing the minimum amount of metal for the required strength, are also so constructed that a Weather strip can be readily provided so as to effect a weather proof seal between the frame and the sash.

Another object of the invention is to produce a window frame bar that is substantially a duplicate of the window sash and which is of such construction that it can readily be built into a brick wall and form with the latter a wind proof seal.

The above and other objects that may become apparent as this description proceeds are at tained by means of a construction and an arrangement of parts that will now be described in detail, and for this purpose reference will be had to the accompanying drawing in which the invention has been illustrated in its preferred form, and in which:

Figure 1 is a section through a window frame and sash showing the parts in closed position;

Figure 2 is a top plan view of one corner;

Figure 3 is a section taken on line 3-3, Figure 2; and

Figure 4 is a fragmentary section to a scale substantially twice that employed in Figures 1 and 3 and shows with greater detail the weather strip and its relation to the other parts.

In the drawing reference numerals l and II designate the inner and outer course of bricks, respectively, in a vertical wall. Reference numeral l2 designates a pane of glass that is secured to the window sash by means of putty l3. The invention to which this application relates 2 Claims. (CL 189L65) has reference to the shape and construction of the window sash and window frame, which will now "be described in detail. The window sash is 'of substantially Z-shape and has a vertical web I4 provided at its upper edge with an outwardly extending flange l5 and at its lower edge with a flange 16 that extends in the opposite direction from flange l5 and terminates in an upwardly extending rib ll. Flange l5 overhangs the outer wall of web l4 so as to form a rib l8 against which the putty can be positioned. The window pane rests on the upper edge of rib I! and is held mpieee by the putty in the usual manner, The under surface of flange [5 is provided with two parallel ribs l9 that are spaced apart and have their inner walls upwardly flaring when viewed as in Figure 1. The weather-strip 20 is positioned between ribs IS in the manner shown more clearly in Figure 4. The window frame is of substantially the'same shape and size as the window sash and with the exception of the part positioned below line 2| in Figure 1, the two mem bers are identical in shape and size. Instead of a short rib like that designated by reference numeral H, the window frame has a wide web 22 that'terrninate's in an outwardly extending flange 23 which projects into the space between adjacent brick courses. The window frame has a vertical web Ma, a wide flange Hill and spaced parallel ribs l9a. The upper flange Ilia corresponds to flange [6 of the window sash.

Referring now more particularly to Figure 4, it will be seen that the two ribs l9 have their inner surfaces downwardly flaring so as to form a. dovetail slot. Positioned in this slot is a weather strip formed from spring metal and bent into the shape of a V. The weather strip is of such size that when it lies in the dovetail groove with one side against the bottom, it is held in there quite firmly because the width is so selected that it can be snapped into position and will remain until it is removed by means of a suitable tool. The free side, which is at the top in Figure 4, and which has been designed by reference numeral 24, normally extends over the tops of the ribs [9, as shown most clearly in Figure 3. When the window sash is closed, the weather strips. both at the top and the bottom, when viewed as in Figure 1, are deformed so as to permit the edges of the ribs to come into very close engagement with the opposed surfaces. The parts may be so adjusted that there is direct contact between ribs l9 and the opposed surfaces, but it is preferable if a short space is left as the sealing is taken care of by the weather strip and not by angular relation as shown in Figure 2.

ance when made from aluminum or aluminum alloy.

Window frames and window sash made of metal are usually mitered at the corners and then welded by a flash welding process. This process necessitates the forceable compression of the opposed edges and this leaves an unsightly ridge along the weld. With the present construction, the ends are cut at the desired angle by means of a suitable metal saw and they are then adjusted into closed contact and right Instead of welding an angle iron like that designated by reference numeral 25 is riveted to flanges i4 and Ma in the manner shown in Figure 3 and this angle is also secured to flanges I5 by rivets 26. When a joint is constructed in the manner just described, care being taken to keep the mitered edges in close contact, the joint between the two parts of the frame is almost invisible and the surface along the joint is smooth.

Particular attention is directed to the weather seal and to the manner in which it is secured in position between the ribs 19 and in the dovetail groove thus formed. This form of weather :strip can be used with the construction of sash and, if not too thick, will adapt themselves to irregularities in the opposing surfaces. Since the frame members are extruded, the surfaces are, however, very smooth and as a result the, seal is very effective at all points.

Having described the invention what is claimed as new is:

1. An elongated structural bar for use in making window frames having, a web, a first flange projecting laterally from the web along one edge thereof, a second flange projecting laterally from the other edge of the web and in a direction opposite to the first flange to form a substantially Z-shaped cross section, a third flange projecting from the free edge of said first flange in a direction towards said second flange and parallel to said web, the width of said third flange being less than the width of the web, and a fourth flange projecting laterally from the edge of said third flange in the same direction as the first flange and parallel thereto, said fourth flange forming means for effecting a connection with the building wall.

2. An elongated structural bar in accordance with claim 1 in which the surface of said second flange that faces towards the plane of the first flange, is provided with two parallel spaced ribs adapted to position a resilient seal element.
