3Claims.

This invention relates to window constructions, and particularly to window constructions for rail- -way cars, buses and the like, andl has for its ob- `iect a construction, whereby the window sash is weather tight in the windowv frame or window opening and conforms to irregularities in the window frame or opening and to misalinements or out o1' parallels between the sash and the window frame or opening throughout the circumference of the sash.

- More speciiically, it has for its object, a metal sash having on the side or out of the plane of the sash, an angular flange extending entirely around the sash, that is, a ange extending along the bottom rail, stiles and top rail, and a. compressible resilient strip between the outer edge of the ange and the wall of the Window opening, this strip preferably extending in a widthwise direction from a point near the sash to a point beyond the outer edge of the flange, and the flange coacting with or pressing on the strip intermediate of the lengthwise edges of the strip.

'Ihe invention consists in the novel features and in the combinations and constructions hereinai'ter 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.

Figure 1 is an enlarged fragmentary isometric sectional view through the sash and the contiguous portion of the window frame.

Figure 2 is an elevation of the sash on a rei duced scale.

I designates a window frame confining the Window opening, and in the drawing, the part l is illustrative of the bottom rail, stiles and top rail of the window frame. 2 designates thesash, which is usually of metal, and 3, the glass panel mounted in the sash. As here shown, the sash is formed with a right angular recess 4 in which is mounted a resilient backing 5 for the margin of the glass panel 3. The glass panel is held in the recess by a removable glazing strip 6 of compressible resilient material, as rubber, this having a base portion snugly fitting in a groove 1 formed in the sash anda head or bead portion pressing against the outer portion of the glass panel I.

'I'he glazing strip is removable for the purpose of removing or replacing the glass panel 3 without demounting the sash or without removing one of the parts, as the top rail, of the sash.

The sash 2 is also formed' with a circumferential :tlange I on the outer side thereof Vwhich laps the margin of the window frame or car body around the outer side of the window opening, and a suitable weather strip 9' is interposed between in position by screws, as the screws I0, extending edgewise through the sash and into the window frame. The sash is formed of metal and' in so far as possible, hollow, and the screws are placeable in position through holes Il opening through the l0 bottom of the recess 4. The screws here shown are of the type which drill and tap the hole while being driven. The strip 9 may be omitted, and

especially that portion between the edge of the sash and the window frame. Y

Oftentixnes, because of variations, irregularities and misalinements in the Window openings, the space between different portions of the edge of the sash and the window opening, varies. The means compensating for the variations and for making the sash weather tight comprises a strip l2 of compressible resilient material, as rubber, located at one sid'e or along the inner side of the sash and extending throughout the length of the top and bottom rails, and the stiles and the sash. For the purpose of compressing the strip, the sash is formed on the inner side thereof, that is, the side toward the interior of the car body, with a flange I3 along the top and bottom rails and the stiies, this flange pressing on the strip along the median line or between the side edges thereof. As here shown, the strip is formed with a groove i4 and a should'er I 5 at the entrance `of the groove, and the flange is formed with a lip I6 fitting into the groove and a bearing surface pressing on the shoulder l5. When the window is assembled in position, the strip is compressed along the four sides and corners of the sash and renders the sash weather tight. Also, owing to the fact that the flange presses on the Vstrip along the median line, the inner side of the strip comes close to the face of the sash. The face of the strip coacting with the window frame is formed concave, at l l, so that the strip, when compressed, presses tightly near its side edges at I8 and I 9 45 on the Window frame and readily conforms to variations, irregularities, misalinements, etc., of the window frame or opening relative to the sash.

What I claim is:

1. 'I'he combination with a window frame; of a Window sash mounted in the frame, a strip of compressible resilient material located in the win- .dow opening throughout the inner circumferential wall of the opening and coacting with the 2 window frame at one side of the plane of the sash, and means on the sash for pressing said strip against the window frame throughout the inner circumferenceV of the window frame.

2. The combination with a window frame; of a window sash mounted in the frame, the sash having a laterally extending flange on one side thereof opposed to the surface of the wall of the frame ooniining the window opening throughout the inner circumference of said opening and out of the plane of the sash, and a strip of compressible resilient material encompassing said flange between said flange and said surface.

3. 'Ihe combination with a window frame of a window sash mounted in the frame, the sash having a laterally extending flange on one side thereof opposed to the surface of the wall of the frame confining the window opening throughout the inner circumferential wall of said opening and out of the plane of the sash. and a strip of compressible resilient material encompassing said flange between said anse and said surface, said flange coacting with the strip intermediate of the side edges of the strip and one side portion extending under the fianze to a point adjacent the sash.
