ATTORNEY United States Fatent WINDOW AND STORM SASH ASSEMBLY Benoit M. Singleton, Middlebury, Ind., assignor to Woodlin Metal Products, Marshall, Mich., a corporation of Michigan Application May 3, 1956, Serial No. 582,413 Claims. (Cl. 189-69) The present invention relates broadly to window constructions, and in its specific phases to a window assembly having an inbuilt storm sash as a part of same.

Double pane windows with a sealed air space are used for heat insulation purposes, but such are satisfactory only as long as there is no leak of air into the space between panes of glass since as soon as that happens the window becomes subject to condensation of moisture on the inner surfaces between panes, and moreover such double pane windows are exceptionally expensive. This has led to the continuing use of conventional storm sash with various ways of mounting same on the Window frame, and even the use of clips for mounting a thin edged storm sash direct on a window sash suited for house trailer use. The complete lack of a unitary window and storm sash construction especially adapted for house trailer use and commercially feasible, led to the conception and development of the present invention.

Accordingly among the objects of the present invention is the provision of a window intended primarily for use such as in a house trailer and it aims to provide a new and improved construction for excluding cold.

A window sash is provided, said window sash having a metal frame and an elastic gasket which holds a light in said frame, and an object of the invention is to provide a storm sash having a frame which lies against and seals on a portion of said gasket.

Another object is to provide a novel construction for hingedly mounting the window sash and the storm sash, each hinge comprising a flange integral with a frame member and having an integral curl at its outer edge, and another flange integral with a sash member and having an integral bead turnably received in said curl.

A further object is to provide a frame construction which may be manufactured from lengths of extruded metal, some of said lengths having the required flanges, curls and beads to form the sash hinges.

Still further objects and advantages of the present invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but several of various ways in which the principle of the invention may be used.

In the annexed drawings:

Figure l is an outer side elevation showing a construction in which both the window sash and the storm sash are hingedly mounted at their upper edges.

Figure 2 is an enlarged fragmentary sectional view on line 22 of Figure 1, looking in the direction of the arrows and with the window sash and the storm sash being in closed position.

Figure 3 is a similar view but showing both sashes swung bodily outward.

Patented June 9, 19519 Figure 4 is a similar View but showing the window sash closed and the storm sash swung outwardly.

Figure 5 is an outer side elevation showing a construction in which the window sash is hinged along one vertical edge and the storm sash along its upper horizontal ed e.

The construction shown in Figures 1 to 4 will first be described. In these views, a window frame 7, a window sash 8, and a storm sash 9 are shown. The window frame 7, the frame 10 of the window sash 8, and the frame 1 1 of the storm sash 9 are all formed from extruded metal bars suitably joined at the corners of the respective frames.

In the following detail description, all reference numerals used will be found on Figure 2, whereas only the principal numerals have been applied to Figures 3 and 4.

The upper member 12 of the window frame 7 is provided with an integral, outwardly projecting, longitudinal flange 13, the outer edge of said flange being provided with an integral curl 14 extending in a substantially straight line from end to end thereof. This curl 14 extends downwardly at 15, inwardly at 16, and upwardly at 17 with respect to the flange 13 and forms one element of a hinge for the window sash 8.

The upper member 18 of the Window sash frame it) is provided at its upper edge with an integral, outwardly projecting, longitudinal flange 19 which underlies the flange 13, said flange 19 having a downwardly and inwardly curled outer edge forming a bead 243 which is turnably received in the curl 14, thus hingedly mounting the window sash frame It on the window frame 7.

Below the flange 13 of window frame 7, the upper member 18 of the window sash frame it) is provided with a lower integral flange 13a having a curled outer edge 14a. This flange 13a and the curled edge 14a are identical with the flange 13 and its curled edge 14 and detail description may therefore be dispensed with.

The upper member 21 of the storm sash frame 11 has an integral flange 19a at its upper edge and underlying the flange 13a said flange 19a having a bead Ztla turnably received in the curl 14a to hin edly mount the storm sash frame 11 on the window sash frame 10. The elemerits 13a, 14a, 19a and Zila are duplicates of the elements 13, 14, 19 and 20 above described and further description may therefore be dispensed with.

The inner perimeter of the window sash frame It) is formed with a channel 22 in which an elastic gasket 23 is seated to mount the light 24. This gasket 23 projects beyond the channel 22 as shown, and makes possible, in addition to supporting light 24, a side seal on the storm sash as will be hereinafter described.

The storm sash frame 11 has a channeled portion 25 in which a gasket 26 is received for mounting the storm sash light '27. The inner side of the channeled portion 25 lies against the side of the portion of the gasket 23 which projects out of the channel 22, for weather exclusion. Thus a substantially sealed air space is formed between sash lights 24 and 27 to form an eflicient pocketed air space, and yet same has the advantages of removability of the storm sash, and in case of moisture condensation between lights, same can be readily wiped away without the necessity of removing the storm sash.

A turn button 28 is shown for normally holding the storm sash frame 11 against the gasket 23 but not sufficiently tight to cause serious relatively permanent sweating of the adjacent faces of lights 24 and 27, and yet such turn button makes it easy to pivotally swing the storm sash outward for wiping away any condensation which may form on the inner faces of the lights 24 and 27.

Both sashes 8 and 9 may be swung bodily outward as seen in Figure 3, or the storm sash 9 may be swung outwardly from the window sash 8, as seen in Figure 4, thus making a very flexible type of construction.

The hinges for the two sashes effectively exclude'rain, and a weather seal all around between the window sash frame 8 and the window frame 7 may be'provided by using any suitable form of gasket 29, one type of which is shown.

In Figure the window sash 30 is mounted on the window frame 31 by means of a vertical hinge 32 of conventional type, and the storm sash 33 is mounted on said window sash 30 by means of a horizontal hinge 34 constructed as above described.

From the foregoing, it will be seen that a novel and advantageous window and storm sash construction has been disclosed for attaining the desired ends. However, it is to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as it has been described above.

Other modes of applying the principle of my invention may be employed instead of those explained, change being made as regards the window and combinations herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention:
