Ffi th f dbi ts d'a en asea invei 'e'on'wm be asphalt from the following specification and the accompanying drawings, wherein a preferred embodiment of the invention has been shown and described.

In the drawings:

Figure 1 is a front view on a vertical plane of a window with a fixed upper sash and movable double hung lower sash, with the weather stripping indicated by hidden lines.

Figure 2 is a cross-sectional view, in part, of Figure 1 on the line 2-2, showing the weather stripping in position on the cross-rails of the lower sash.

Figure 3 is a cross-sectional view, in part, of Figure 1 on the line 33, showing the method of turning the weather stripping about the end of the upper sash rail of the lower sash.

Figure 4 is a cross-sectional view of the weather stripping material used.

Similar numerals refer to throughout the several views.

As illustrated in the drawings, the fixed upper sash I is formed and constitutes a part of the main frame 2, with a formed bottom cross-rail 3, which has a plurality of Walls and protrusions, including the wall 4. The double hung lower sash 5, movable in a vertical plane, has the side rails 6 and l and the top and bottom cross-rails 8 and 9, respectively. The side rails 6 and 1 have a channel l0, accommodating a U-shaped weather strip H which in turn contacts intimately the sash guide [2, forming a Weather seal between said side rails and the window frame.

The formed bottom cross-rail 9 has an elongated leg I3 which is inturned at its end forming the groove [4, with a similar groove l5 formed at its inside base, said grooves l4 and I5 and the similar parts ,2 inside rate a: "said time reef-leg marina the lengt t me ,rbf s'eir 1i metal binder l8 on'thewather's L or inserted, said weather'str ping the ends of said bottom crass ail strip consists 'of'the' 'pi'l e 'll witlfljtswoye 1? Iii firmly held-in the metal binder F. T H abuts against and tely inner face I821 of [the fa making a weather "seal bet and the bottom 'of'the'windo-w frame 2."as-s1'i0w inFigureZ.

A mor'e'uimcu t problem is ing; a, weather seal between 't e an the 'upp'ersash I jandthef ofthe loweifsa'sh 5, liarti cularly opening [9 between thend'o' and the adjacent wall of'the simple in construction and free ro which tend to loosen under constant operation of the sash. I accomplish this by forming the channel 20 in the wall 2| of the cross-rail 8. said channel extending the entire length of said rail. In this channel 20, the metal binder I6 of the weather strip is journaled or inserted, the pile I'I thereof abutting against and intimately contacting the adjacent face of the wall 4 of the bottom rail 3 of the fixed upper sash l, making a weather tight seal therebetween. The channel 29 in the horizontal rail 8 extends to the out side perimeter of the sash 5, regardless of the corner joinery used. The weather strip inserted in said channel 20, is continued and bent in U- shape about the leg 22 of the side rail 1, where it is held in position by the metal binder [6, the pile I1 thereof abutting against and in intimate contact with the sash guide [2 and the inner face of the wall 4 of the cross-rail 3, which is extended and warped against and fastened to the frame I, as by the rivet 23, as shown in Figure 3, thereby filling and weather sealing the opening l9 between said cross-rail 8 and the window frame 2. While I have described in detail above in respect to the weather stripping of one end of the cross-rail 3, it is obvious that the same methods apply to the opposite end of said rail.

Marked advantage results from the method described above of weather stripping the sash at the meeting rails and the end opening, in that the weather stripping itself may be easily replaced, if desired, and no additional parts or members are required, which, due to space limitation and lightness of construction, present many difiiculties during a period of continued operation.

While I have shown and described herein, for

said binder inserted in said channel extending 7 beyond the ends of said channel, the extensions of said weather strip conforming to exterior surfaces of the vertical rails.

2.In a window consisting of a formed main frame, upper sash and lower sash, each of said sash having horizontal and vertical rails, said vertical rails being joined to said horizontal rails at their respective ends, a formed horizontal upper rail in said lower sash having a continuous channel therein extending the width of the said sash, adjacent to an abutting horizontal rail of said upper sash, and a weather strip consisting of a metal binder and woven pile fabric firmly held in said metal binder inserted in said channel, said weather strip extending beyond the ends of said channel and conforming to exterior surfaces of the adjoining vertical rails, where it is held in position by said metal binder, weather sealing the opening between said sash and the main frame.

3. A window construction consisting of a formed main frame with a fixed upper sash and vertically movable lower sash, a formed horizontal upper rail in said lower sash having a groove therein extending the Width of said sash adjacent to an abutting horizontal rail of said upper sash, and a weather strip consisting of a binder and 4 woven pile fabric firmly held in said binder insertedin said groove and extending beyond the ends of said groove, said weather strip extensions conforming to exterior surfaces of said lower sash adjacent to said main frame.

4. In a window sash having upper and bottom horizontal rails and vertical rails joined to said horizontal rails at their respective ends, said sash being slidable in a supporting frame; a resilient Weather stripping positioned on the side of the upper horizontal rail throughout its length and extended around the end of said sash, closing the opening between said sash and the supporting frame.

5. In a window having a plurality of sash vertically slidable in a supporting frame, each of said sash having joined horizontal and vertical rails, the exterior side of said vertical rails adjacent to said frame having a channel contour accommodating a sash guide on said frame; a resilient weather stripping positioned on the side of a horizontal rail adjacent to a rail of an abutting sash, extending beyond the ends of said horizontal rail in substantially U form, embracing said contour in each of the joining vertical rails and intimately contacting the abutting frame.
