ATTORNEY April 26, 1960 w. J. LIVSEY ETAL WINDOW CONSTRUCTION 3 Sheets-Sheet 3 Filed Sept. 17, 1957 INVENTORS H V ww n w m E .4 UM Q MW wmfi This invention relates to a window-sash construction and more particularly to the weatherproo'fingof window sashes of the type wherein the stiles of the s ash a epi'viorally mounted to and between supports slidably mounted in guides in the window frame whereby a single sash or-an upper or lower sash of the window maybe opened by rotative movement While, at the same time, providing for a vertical upward and sliding movement of the sash. f

It is the primary object of the present invention to provide improved means arranged along the stiles of the sash which co-operate with means arranged along'thesash supports to seal the space therebetween when the sash is fully closed so as to ettectively prevent the passage of air, moisture and dust and other foreign elements therebetween.

It is another object of the invention to provide an improved weatherproofing means for window sashes of the rotative type which not only acts to prevent the passage of air, etc., between the same and its supports but also acts as a stop so as toproperly seat and lock the sash in a Patented Apr. 26,, 1966 zontal axis, each of the sashes may be tilted or turned so that access may be had to the outer side of the sashes from the inner side of the window, as will be apparent fromFig, 3. v,

According to thepresent invention, there is arranged along the outer edge of each of the stiles4 of each of the sashes, a pair of elongated weatherproofing strips 7 and 8 which are substantially L-shaped in cross-section so as to provide a bottom leg portion 9 and an upwardly extending leg portion 10. This bottom leg portion consis'tspreferably of a double thickness of the material i.e. the ma terial is folded upon itself to form this substantially V- shaped bottom leg so as to provide a resilient lip portion 12.

v The strips are made preferably of a relatively thin, flat, strip of metallic material having resilient characteristics. One is disposed to either side of each of the pivotal cong nections 5 and extends therefrom to the outer ends of the respective stiles 4. The strip' on one side of the pivotal connection 5 of each of the stiles is disposed opposite't'o' that positioned on the other side of the pivotal connection vertical position in its frame when the window is moved- 6 to its fully closed position. 7 It is a further object of this invention toprovide an improved window construction of the rotatable sa'sh type wherein there is provided means for'holding the sash and supports therefor under spring tension so as to prevent rattling or the sash in the supports, which means also efficiently and elfectively seals the space between the sash and the supports when thewindow is rotated to its closed position. v 1 I Various other objects and advantages of this 'vjention will be more apparent in the course of'the fol 'w ng .specification, and will be particularly pointedou' iithe ap pendedclaims. Y f In the accompanying drawings, there isshown forthe purpose of illustration, anembodirne'nt whichour invention may assumeinpractice.

Referring morepa'rticularly to the drawings,"the improved's'ash construction of the'present invention may be incorporatedin any conventional type double-hung win 'dow frame 1 having oppositely disposed guideways 2 and 3 with upper and lower sashes,'respectively" Eachof the sashes comprises a pair of side stiles 4 which are 'pivotally attached centrally thereof,as at-S, to the vertical supportfor a purpose hereinafter to be described. 5;

There is arranged in the outer edge of eachof the stiles 4, a pair of spaced-apart longitudinally extending slots 01' grooves 13 and 14-. The bottom leg portion 9; together with the lip portion 12 carried thereby is disposed in the I slot or groove l3'on one. side of the pivotal connection 5, and the bottom leg portion 9 of the strip disposed or wedged on thetopposite side of thetpivotal connection is disposed or wedged in the'slot or groove 14011 the op posite side thereof so that the vertical leg portions 10 extend inopposite directions, one toward the inside of the sash andthe other toward the outside thereof, as more c'learly shown in Figs. 3 and 6 of the drawings.

on the inner side of each of the supporting members 6, there is arranged a longitudinally extending groove or slot 15 so as to provide stop shoulders or ledges 16, 'and' 1'7 therealong with which the free edges 18 of the weatherstrips 7 and 8 cooperate in a manner presently to be described. a I

When the sashes fare in their fully rotative closed positions, as shown in Fig. 1, 4, and.5,.it will be seen that the freeedges 18 of each-of the strips 7 and 8 lie in the respective grooves or slots 15 in the supporting members 6 and abut the respective shoulders or ledges 16 and 17 therein. That is to say, that, the free edge of the strip 7 on one side of the pivotal connection 5 of'each of the sashes will abut the shoulder or ledge 16 of the respective grooves 15 and that the free edge of the strips will abut the shoulder or ledge 17 on the opposite side of the pivotal connection so as to etfectively seal the space between the outer edge of the stiles 4 and the supporting members 6.

It will be seen that these free edges 18 of the stripsnot only lie in the grooves or slots 15 so as to effectively seal the space between the supporting members and the stiles ofthe sash but also co-operate with the shoulders of ledges 16 and 17 so as to provide a stop for further rotative movement'of the sash. That is to say, the free edges of the stops will abut and seat against-the shoulders'16 and 17 so as to prevent continued rotative movement of the window past its fully closed position. -Also, the strips 7 and 8, due to the resilient characteristicsthereof, hold the sash in the supporting members under tension so as to prevent any lost motion or rattling of the sash inthe supports. When the sash is moved or swung to an:

open position, as shown in Fig. 3, and the dotted lines of Fig. 2, the leg portions 10 of the strips 7 and 8 spring outwardly from the stiles and are disposed angularly relative thereto and act to frictionally hold the sash in its open position. I

Between the twosashes there is positioned a frame 2 having a screen 21 arranged therewith. This, frame 21 is arranged in the frame 1 between the supporting members 6 with the sides of the screen frame arranged slidably in grooves 22 positioned between the guideways 2 and 3 so that the screen may be raised or lowered. Thus, it will be seen this screen can be disposed opposite the opening of either the upper or lower sash, as desired.

As a result ,of our invention, it will be seenthat there is not only provided a window construction which is simple and economical in its manufacture but at'the same time efficient and effective in its use.
