SPECIFIGATIGN forming part of Letters Patent No. 775,866, dated November 22, 1904. Application filed January 16, 1904. Serial N0. 189,268. (No model.)

To rl/ZZ whom, t may colto/fm1.'

Beit known that I, ANDREW G. S'rrnNnnnN- NER, a citizen of the United States, residing in the city ot' St. Louis, in the State ot' Missouri,

have invented certain new and useful Improvements in Vindows, of which the following is a Yfull, clear, and'exact description, reference being had to the accompanying' drawings, forniing part of this specication.

My invention relates to an improved construction for rendering the windows el. buildings air-tight throughout; and the invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is an elevation of a portion et a Window with my improvement shown applied thereto. Fig. II is a vertical section taken on line II II, Fig. I. Fig. III is a perspective view of one of the sash-receiving strips.

2o Fig. IV is a' perspective view of the edge of one of the window-sashes that enters into the strip shown .in Fig. III. Fig. V is an enlarg-ed vertical section taken on line VV, Fig.

I. Fig. VI is an enlarged horizontal section taken on line VI VI, Fig. II. Fig. VII is an enlarged section taken on line VII VII, Fig.

I. Figa-VIII is an enlarged section taken on line VIII VIII, Fig. II.

l designates the uprights of a windowframe that is furnished with the usual inner and outer stops 2 and 3 and parting-strips t.

5 isthe rabbeted window-frame sill, and 6 the lintel or' the frame.

7 designates the side stiles ot' a lower window-sash, 8 the bottom rail, and 9 the meetingrail of said sash. IO represents the side rails of an upper sash, and l1 and 12 are respectively the top and meeting rails of saidsash. The edges of the lower-sash stiles? taper down- 40 wardly in wedge form, as seen in Fig. IV,

and the stiles IO of the upper sash taper upwardly or inversely to the taper of the lowersash Stiles.

13 designates downwardly-tapering sashreceiving strips of channel form that are secured in the sash-runways between the inner window-stop 2 and the parting-strip 4 and which extend from the window-sill 5 upwardly to a point above that occupied by the meetingl l l l j rail or' the car-whidow sash when said sash is 50 in closed position. As stated, these strips are ol channel form, the channel shape being due to the existence of a iiange I4, projecting 'from one edge oi' each stri p, and an inwardly-curved spri11g-tongue 15, projecting from the opposite edge ot' each strip, as seen most clearly in Figs. III and VI. The channel-strips 13 re-` ceive the tapering edges ot' the lower-sash stiles 7, that are held snugly therein, due to the impingement or' the flanges la and spring- 6o tongues l5 against the taperinginclosed sides ot' the sash-rails. At the lower narrow ends ot' each channel-strip is an imvardly-extending tongue 13, that projects Vfrom the main body of the strip and receives the edge face otl the adjacent sash-Stiles, as seen in Fig. VIII. to thereby prevent edgewise play o1 the sash in addition to the prevention oi: lateral play overcome by the iiange and spring-tongue ot' the strip. It will therefore be seen that when 7o the sash is lowered its stiles on'moving downwardly in the channel-strips will become laterally wedged between vthe ianges ot' said strips at one side and the spring-tongues at the opposite sides, thereby creating a close joint between said members through which air cannot pass. l

13 designates upper channel-strips oll similar shape to thechannel-strips 13 and positioned in the sash-runways of the upper sash between 8O the outer window-stop 3 and parting-strip si, these strips having' l'langes 14; and springtongues l5. The only distinction between these upper strips and the lower strips is that their position is inverted with respect to the 8 5 position ot' the lower strips, so that the upper sash will be wedged tightly therein when itis moved upwardly into closed position, as distinguished :from the downward movement oli the lower sash when it is moved into closed position.

16 designates a top channel-strip secured to the lower side of the window-'frame lintel 6 at the top et' the upper-sash runway, this strip being provided with a flange I7 and a spring- 95 tongue IS, between which the top rail ll oli the upper sash enters when said sash is in closed position. (See Figs. II and V.) This top strip by receiving the top rail of the upper sash serves to exclude the entrance of air l around said top rail when the upper sash is in closed position.

19 designates a spring-strip secured to the window-sill and having a wing 20, that extends downwardly into the rabbet of said sill to receive the engagement of the lower-sash bottom rail 8 when the lower sash is moved into closed position. The wing 20 overhangs the lower portion of the sill, as seen in Figs. II and VII, and is separated from the sill, so that it will yield when the bottom rail of the sash is lowered thereto and will be maintained in close contact with said bottom rail to exclude the entrance of air past the rail.

2l is a weather-strip secured to one of the sash meeting-rails (see Fig. II) that serves to exclude the passage of air through the interstices between the meeting-rails.

I claim as my invention- 1. In awindow, the combination with asash and frame in which said sash operates, of tapering channel-strips arranged to receive the stiles of said sash, substantially as set forth.

2. In awindow, the combination with a sash and frame in which said sash operates, of tapering channel-strips arranged to receive the stiles of said sash; said channel-strips being furnished with a spring-tongue extending longitudinally thereof, substantially as set forth.

3. In a window, the combination with asash and frame in which said sash operates, of tapering channel-strips arranged to receive the stiles of said sash; said channel-strips being furnished with spring-tongues extending longitudinally thereof, and spring-tongues located within the channels of the strips,substantially as Set forth.

4. In a window, the combination of upper and lower sashes and frame in which said sashes operate, downwardly-tapering channel-strips to receive the stiles of said lower sash and upwardly-tapering channel-strips to receive the stiles of said upper sash, substantially as set forth.

5. In a window, the combination with upper and lower sashes and a frame in which said sashes operate, of a pair of downwardlytapering spring-strips to receive said lower sash, a pair of upwardly-tapering springstrips to receive said upper sash, each of said strips having a longitudinally-extending side ange and alongitudinally-extending springtongue between which the stiles of the sashes operate, substantially as set forth.

6. In a window, thecombination with an upper sash, of a frame having a lintel, and a channel-strip located beneath said lintel to receive the top rail of said upper sash, said channel-strip having a downwardly extending flange and a downwardly-extending springtongue, substantially as set forth.

7. In a window, the combination with a frame, of a sash arranged to operate in said frame, spring channel-strips to receive the Stiles of said sash, said stiles being of tapering or wedge shape to correspond to the shape of the channels in said strips, substantially as set forth.
