1 claim. (c1. 1s9-6s) The invention relates to window constructions and has for its object the obtaining of a construction in which all portions of both the frame and sash or. sashes may be formed of extruded metal bars.

The invention consists primarily in characteristics of said bars and the manner in which they are united with each other.

The invention further consists in more specific features as hereinafter set forth.

In the accompanying drawings:

Fig. 1 is a front elevation of my improved window construction which is specifically shown as a multiple swinging sash construction;

Fig. 2 is a vertical cross-section therethrough showing only two of the sashes of Fig. l, parts being broken away;

Fig. 3 is a rear elevation of a portion of the window sash.

In the present state of the art certain metals and particularly aluminum and its alloys may be readily formed into bars of any desired cross-sectional contour by extrusion. I, therefore, form both the window frame and the sash of extruded bars which are of such cross-section as to interfit with each other and to require but little work thereon other than the forming thereof into rectangular frames. One characteristic of these bars is that they are composed of web portions having generally parallel opposite faces and which adjoin each other to form the desired contour. This lightens the structure and also produces both the required functional characteristics and -.the desired ornamental appearance.

As illustrated A is the bar for forming the window frame which includes web portions A and A2 extending generally at right angles to each other and a web portion A3 extending from the portion A2 oppositely from the portion A and generally parallel but spaced therefrom. Bars as thus far described may be formed into a rectangular frame by bevelling opposite ends of suitable length thereof for forming respectively the horizontal and vertical sides of said frame and uniting the same preferably by welding. If the frame thus formed is intended for use with multiple sashes it may be provided with one or more intermediate bars of a modified cross-section to be later described. These also may be secured by bevelling the opposite ends thereof to engage bevelled ends of sections of bars forming the opposite side of the frame. The bars B for forming each sash have generally parallel outer and inner web portions B and B2 connected by a portion B3 to constitute a U-form. A web portion B4 extends from the portion B' intermediate the ends of the latter towards the end of the portion B2 but leaving an open slot B'I therebetween. The sash is formed by horizontal and vertical sections of the bar B bevelled at their opposite ends and united to each other preferably by welding. If the sash is to swing in relation to the window frame its top rail is modified in the construction f the extruded bar by having a portion B5 of spiral cross-section united to and projecting from the corner connection 2,797,778 VPatented YJuly 2 1957 betweenthe portions B and B3. Also, the adjacenthori- `zontal `bar of the `window frame is `provided with such :a

Aplaced on one or'r'hore intermediate rbars for the hinging o'f'sas'hes below'the satire".

Such intermediate frame bar C iis of a cross-section which combines portions of the top bar and bottom bar of the frame. These include pairs of web portions C' and C2 corresponding to the portions A2 and A3 of the top and bottom rails of the frame and a central connecting portions C3 in place of the portion A. A spiral portion C4 is connected to the portion C3 similar to the portion A4 on the top rail of the frame. This will furnish a weatherproof hinge member for supporting the lower sash while the upper portion of the bar will form a seat for the sash above the same. To produce a weather sealing joint between the sash and the frame the p0rtion A3 and also the portions C2 are each provided with a channel for receiving a sealing strip. Thus, as shown in connection with the portion A3, this channel is formed in the lower part thereof, which is slightly olset laterally from its upper part. Also, projecting ribs A5 and A6, respectively, at the top and the bottom of the channel serve to retain therein a resilient sealing strip D. The sash rail B has the portion B3 thereof projecting beyond the portion B2 to form a rib B6 which contacts with the strip D to form the sealing joint. This strip D may be hollow as shown to form a more yielding resilient bearing for the rib B6. The glass E for the sash is seated in the angle between the upper part of the portion B and the portion B4. The sealing joint is formed by a strip F of resilient material which extends around the margin of the glass on the front face and all sides thereof and also overlaps the edge of the glass. This strip is seated on the portions B and B4 of the sash rail. To retain the glass resilient bars G of generally V-shaped crosssection extend along each rail of the sash in rear of the glass, being mitered at opposite ends to adjoin each other at the corners. One leg G of the V engages a groove B8 in the outer edge portion of the web B2. The other leg G2 may be entered into the slot B7 so as to bring the portion of the bar near the apex against the inner face of the glass. The bar will be held in this position by a latch portion G3 which hooks around the edge of the web B4 and resiliently presses the bar against the glass.

The Window construction as above described will form a perfect weather seal when the sash or sashes are closed and locked in closed position by any suitable means (not shown).

To secure the Window frame to the wall a series of clips E are engaged with a ledge A7 formed on the inner end of the portion A2 of the frame, said clips being nailed or otherwise secured to the wall. Also, a sealing strip F is placed between the portion A and the outer face of the wall.

What I claim as my invention is:

A Window construction comprising a frame and a plurality of individually hinged pane holding sashes, all in `the same plane and seated in said frame, both frame and sash being formed of extruded bars cut to lengths with beveled ends and welded to each other, the bars of the frame being of a cross section including offset generally parallel outer and inner portions connected by an intermediate portion at right angles thereto, said frame having one or more intermediate cross bars between sashes, said sash bars being hollow and engaging the space between said outer and inner portions of said frame bars with fa projecting-a'nge'forming a seat for a pane and an inwardly projecting rib for engaging a resilient sealing strip on the inner portion of said frame bar, the upper bar of each sash also having an integral outwardly eX- tendingspiral 'angeland the upper -and intermediate ,frame bars having integral spiral anges cooperating with the aforesaid spiral anges to form hinges.',
