8 Claims.

My invention relates to windows, and more especially to comparatively light window sash structures.

One of my objects is to produce a relatively inexpensive structure of this kind which is readily assembled, especially with respect to mounting the glass plate or plates in the sash.

Another and more particular object is to provide a sash of the type of window screen frames so'that my present invention, constructed as a storm sash, may readily be substituted for the window screen.

A further object is to construct a sash with the foregoing advantages, of sheet metal, in such a way that the various parts may be very easily bent, pressed, or otherwise formed of the sheet metal, and so that where the parts must be fastened together, the fastening may be done by very simple operations; and in general to make m a sash mainly of sheet metal of low first cost,

easy to install and maintain, and which is reliable and durable. Other objects will appear in the course of the following description.

v I'accomplish the above objects by the device as illustrated in the accompanying drawing, in

which:

Figure 1 is a front elevation showing in -general the construction of my improvedsash, intermediate parts being broken away for lack of space.

Fig. 2 is a fragmentary perspective view on an enlarged scale of parts of the sash about midway of its height at the right side as at A in Fig. 1, with one of the mullion strips removed and part of the glass strip broken away so as to reveal the interior details of the construction.

Fig. 3 is a partial horizontal cross section on the plane of the line 3, 3 of Fig. 2.

Fig. 4 is a partial vertical cross section through the mullion on the plane of the line 4, 4 in Fig. 2, but showing both mullion strips and the adjacent parts of both glass plates.

The sash shown for purposes of illustration of my invention comprises, as shown in Fig. 1, the upper glass plate 1, and the lower glass'plate 2, surrounded by the upright side rails 3 and 4, the top rail and the bottom rail 6, which are provided with removable glass strips 7, 8, 9 and 10 respectively, holding the plates 1 and 2 in the sash frame; the sash'rails and glass strips just mentioned being, as here shown, mitered together at the corners 11. It will be understood however, that the joining of themembers atthe corners may take any other well known form, and the present invention is not particularly concerned with or limited to any particular form of corner fastening. 'Ihe two plates 1 and 2 have their edges midway of the height of the sash received in a transverse mullion, which comprisesthe mullion strip 12 at one side of theplates, which is iixed to the side rails 3 and 4 as will be described, and the mullion strip 13 bearing against the other sides of the plates 1 and 2, and suitably removably secured to the fixed strip 12, as also will later be described. The sash, of course, might be one with a single glass plate, in which lo case no mullion would be used, or may have more than the two plates shown, with the required number of mullions; and also it will be understood that while this sash is shown with one plate above another and the mullions transverse, sashes may be made with the plates succeeding horizontally with the mullion or mullions upright; or there may be crossing mullions. In any such cases my invention is applicable and will accomplish the objects above referred to.

Describing the details of the present example specifically, the sash rails, as the side rail 4 in Fig. 2, is practically of L-shape, one of the members 14 which forms the sash rail proper being v of rectangular tubular shape to aiiord the required bulk and strength for the outer structure of the sash, while the other member 15 of the L extends in across the sash inclining inward toward the middle of the thickness of the sash, and having along its inner edge a bead 16 turned in so the same direction. Also, this member 15 has a compound bend 17 where it starts to incline some distance inwardly of the sash from the inner wall 18 of the tubular member 14, which wall has a flange 19 turned inwardly of the sash, with g5 its inner edge along the compound bend 17. This flange 19 is secured to the inwardly extending member 15 preferably by spot welds 20, as clearly shown in Fig. 2.

On the side of the inner inclined part of the member 15, which is toward the middle of the thickness of the sash, is fastened a U-shaped member 21, with the bottom of the U toward the other face of the sash; one side of the U having an extension 22 along the inclined part 45 of the member 15.V It is by this extension 22 that the member 21 is secured to this part l5, also preferably by spot welding, as at 23 in Fig. 2.'v

The other side 24 of this U is thus presented parallel with the inner side 18 of the outer 5o rectangular cross section of the rail, and it is spaced inward from this side 18, and also its edge is free from the opposite inner part 19 of the structure, so that this U-shaped member is resiliently held throughout its length in its element 29 of this L-shape fits into the slot 25V and is gripped between the wall 18 and the side 24 of the U-shaped member by virtue of having the slot 25 left, by the spacing of this member from the slot 18, normally slightly narrower than the thickness of the element 29 which it is to receive, whereby the U-shaped member 21 must yield somewhat upon insertion of the element 29, and will grip this element 29 holding the glass strip 26, rmly in the sash. Y

The glass .plate 1 has its edge portion between the inner edge beads 16 and 27, of the members 15 and 26` respectively, .and itsl edge may rest against the adjacent side of the U-shaped member 21. By having the parts properly proportioned, this glass plate 1 will be held firmly between the two members 15 and 26, the latter member or glass strip 26 vbeing'held firmly in the sash merely by the frictional engagement or gripping in the slot 25, without requiring any other fastening means. i

The fixed member 12 of the mullion is attached to the inner member 15 of the sash rail by means of a cleat` 30, having spot welds 31 fixing it inside the fixed mullion member 12, and being bent at 32 to flt over the bead 16 of the member 15, beyond -which it has its terminal part fixed to this member 15 by a spot weld 33. This mullion member is of shallow channel shape, the middle part being parallel with the plane of the sash, and its lateral portions being inclined like the member 15 of the sash rail, and'having beads 34 turned in across their inner sides at their edges to bear against the edge portions of the plates 1 and 2. It is in the middle parallel part that the cleat is secured. Also in this middle part lugs 35 are secured by spot welds 36, each lug being formed of a metal strip bent into Ushape, with end parts of the U bent outward, which end parts have the spot welds 36. The removable mullion strip 13 is of substantially the same cross section as the fixed strip 12, with beads 37 bearing against the other sides of the plates 1 and 2, and its middle part fltting on the lugs 35, and having openings through which screws 38 pass into Athreaded openings in the bottoms of the U-shapes of the lugs 35. The ends of this removable mullion strip 13 iit snugly against. the beadsf27 ofthe inner edges of the glass strips 26, but do not necessarily overlap them or engage them in any wayto-hold the glass strips in position. It will Vbe seen that the lugs 35 extending between vthe adjacent edges'of the plates 1 and 2, act as a support for the upper plate 1, or should the mulhon be upright, these lugs act as spacers for the plates; so that in any case the lugs 35, together with the other three sides of the space formed by the inner sides of the U-shaped' members 21, confine the glass plates 1 and 2 in position wi the desired closeness.

Itv will be. seen that in the original assembly of the sash and its plates 1 and 2, or in case of replacement of one of the plates,.the operation is made very simple because the glass strips-27 the grooves 25 and the mullion strip 13 may be screwed on; or f or removal of a plate the mullion strip 13 may easily be removed by removing the screws 38, and the glass strips 27 may readily be pried out of their holding positions. It will be noted that these strips when being inserted, have their beaded edges 27 presented to the glass plate, and then the free side portion 29 is forced down into the groove 25; and in removing the strip the reverse of this operation preferably isv employed, ilrst prying the strip loose from the groove 25 rather than acting upon the strip adjacent to the glass.

I have illustrated and described a preferred example of my invention specincally as is re quired, but it will be understood that modifications may occur and that I am not limited to such precise disclosure, but what I claim as new and desire to secure by Letters Patent, isz- 1.
