6 Claims.

This invention relates to window constructions, and has for its object a particularly simple adapter by which two spaced apart glass panels may be supported in a conventional sash intended for supporting one glass panel, which adapter is simple and economical in construction, readily applied to the sash without modifying or materially modifying the sash.

Modern air-conditioning for railway cars, buses 10 and other vehicles and enclosures has developed so rapidly that there are many railway cars, buses. etc. that are comparatively modern in all respects, except for the double windows necessary, or highly desirable, in air conditioned enclosures. 15 The sash equipment of such cars or vehicles is comparatively new and the expense of discarding them for new double sashes is oppressive.

Therefore, the object of the invention is an adapter by which such single sash may be readily and economically adapted for supporting a double glass panel.

The invention comprises, generally, an adapter for supporting a second glass panel spaced from the original or first panel, which adapter comprises a strip formed to interlock with the mounting means of the original or first panel to secure the adapter in which the second glass panel is mounted in spaced relation to the first to the sash with a sealed air space between the panels.

-The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figures 1 and 2 are fragmentary isometric views, partly in section, illustrating the adapter applied to different forms of sashes.

Figure 3 is a fragmentary isometric view of the metal sheath for the glazing strip shown in Figure 2. I

In Figure 1, l designates the bottom rail of a sash originally intended to support one glass panel 2, the side rails or stiles and the top rail being substantially the same as the bottom rail l In the form of the sash shown in Figure 1, one of these rails, usually the top rail, is demountable for the purpose of removing and replacing the glass panel 2. In Figure 1, the sash may be wood or metal and is formed with a channel 3 opening through its inner edge for receiving the margin of the glass panel 2 and the mounting therefor. The mounting is usually formed of rubber or resilient material having a channelshaped portion 4 located in the channel 3 and embracing the margin of the glass panel 2, and with an outer head portion 5 engaging with the glass panel outside of the channel 3.

6 designates the adapter which is formed up of sheet metal in strips of suitable lengths, each provided with a lengthwise portion 1 interlocking with the mounting means for the first glass panel 2 and also with means for supporting a second glass panel 8. As here shown, the lengthwise portion 1 is in the form of a channel embracing the margin of the glass panel 2 and seated in the channel-shaped portion 4 of the mounting for the panel 2. Also, the adapter is formed with a portion located outside the channel 3 at one side of the panel 2, this being angular in cross-section and forming the bottom Sand one side H] of the channel, the side It] being opposed to the panel 2. A suitable mounting II is located in the angular outside portion of the adapter 6, and this includes a spacer l2 interposed between the margins of the glass panels 2 and 8. The mounting II is also formed with a lip I3 covering the edge of the side wall H] of the outside channel portion of the adapter. Thus, in order to convert a single sash of this type into a double sash, the removable rail, as the top rail, is demounted, the glass panel 2 demounted, amounting, as 4, with the head or glazing strip portion 5 located in the channel 3 of the sash, the adapter 6 then placed in position. Then the mounting ll including the spacer l2 placed in the adapter and the glass panels 8 and 2 placed in position and the top rail, which is also equipped with the adapter, and the mountings replaced, so that a sash adapted to support a single glass panel is converted into a sash adapted to receive spaced apart glass panels.

Any known dehydrating means may be used, if desired.

In Figure 2, a form of sash for supporting a single panel is shown in which a removable glazing strip of rubber or similar material is used, which glazing strip is removable for the purpose of removing and replacing the sash instead of having one of the rails, as the top rail of the sash, demountable.

In Figure 2, 2| designates a sash shown as formed up of sheet metal to have a channel for receiving the margin of a single glass panel 22. The channel designated 23 is shown as provided with a bottom portion and with one side flange 24 and as being open at its other side, this latter side being closed by-a removable glazing strip. Normally a suitable lining or mounting 25 of rubber or similar material is located in the channel 23.

26 designates a removable glazing strip of rubber or similar material, this having a base portionfl which extends into a groove 28 located in the sash to the outer side of the channel 23 and having its open edge at substantially the level of the bottom of the channel 23. The glazing strip also has a head portion 29 which presses contour of the head 29 of the glazing strip. Preferably the head 29 is formed with a lip 33 lapping over the outer edge of the sheath to cover the same. The sheath constitutes the subject matter of another application.

In this form of window, the glass 22 may be removed and replaced by demounting the glazing strip 26. The glazing strip or the sections thereof may be readily displaced out of the groove 28, whereupon the remainder of these parts may be displaced out of the groove 30 permitting the glass 22 to be removed and replaced. This type of glazing strip may be of one piece for the entire glass panel, but preferably the metal sheathing is in sections running along each side of the sash, that is, along the bottom rail, stiles and top rail, they meeting at the corners, whether the corners of the glass are square or rounding.

36 designates the adapter for the type of sash shownin Figure 2, this having a lengthwise angular baseportion 31 fitting the channel 23 and interlocking with the mounting 25 or extending between the side walls of the channel 23 and the outer side of the mounting 25. The adapter is also formed with an angular portion located outside the channel 23 on the side of the sash oppo-- 'site to that on which the glazing strip 29 is located, said portion forming thebottom and side flange 39 of an angular groove for receiving'a second glass panel 38. The side wall 39 of said portion is opposed to the margin of the first glass panel 22 or the mounting 25 thereof and the portion of the mounting 25'between the glass panels constitute the spacer. A suitable seat or mounting of rubber for the glass panel 38 is located in the adapter 36. This adapter is preferably made up of sections-meeting at the corners of the sash, w hether the corners are rounding or square.

To adapt the sash for supporting a single glass panel, to carry spaced apart glass panels, the glazing strip 29, glass panel 22 and mounting 25 thereof is removed and the adapter strip seated in the channel 23. The seat or mounting l0 and the second glass panel 38 are then placed in position in the adapter strip, the mounting 25 for the glass panel 22 and the glass panel 22 are then mounted in position, and finally the glazing strip 23 replaced.

The sashes l and 2| are here illustrated as illustrative of standard sashes now in use for supportthe sash.
