wmnow CONSTRUCTION I Reuben B. Andersen, St. ul Minn Application August 3, 1945,'Serial No. 608,791

. My-invention relates to an improvement in indows, wherein it is desired to provide a more o'jtive window structure.

:With most conventional types of double sash in'dows now in use, it is common practice to emy a window screen in the window frame. durin warm weather and in cold climates to replace th s .screen with a storm window during: cold weather. This necessitates changing screens and storm windows twice each year and provides "eifective insulation when it is desired to prevent at from entering thehouse. Somepersons .1 illowthe practice of completely closingtheir house during the hottest hours of the day. Open- ;t hewindows to cool thehouse during thecool hgurs; requires the presence of a screen in the window in most territories. Therefore in the {warmer hours a single double sash window insulatesthe warm air outdoors from thecooler air inside the building. I V s lt is the object of the present invention to proaide a window having two sets of double hung window sashes therein and having a screen -in-. terposed between one window sash and the op'-' jposite end of the frame. The outerinostwinnews act in the capacity'of 'storrn' windows, thus i'e'tviating the nece'ssityof adding storm windows .l'cold'fw'eather. ,At the same time, however,

. 156th of the windows may be-close'd' at any time of theyear toprovide aneifective insulation in hot -1 arena weather. The window may likewise be 0 e'ned'in the usual mannenand the opening 'ec'ted by a screen.

A feature of the present invention lies'inthe ovision'o'fa wide flush still extending inwardly oni'thej inner window in the usual manner, and

extending outwardly 'into' proximity with the outer window. A wide fiat shelf'or table is thus formed when"the"l ower'sash of the inner win- (low israised': added advantage of the sill 40 ddji struction lies in "the fact that the sill itself as be removed rrotn'the outside of the window A further feature of thepresent-invention lies i'n jthe fact that the screen may be opened if a desired to permit'the-window opening to be unobstructed; When bothfof the lowei 'wiridow sashes are in raised position; a'per'son inside the-window has access to'the window screen. The-screen may.

then be swung outwardly and entirely removed if necessary. r H

feature of thepresent invention resides in the provision of a'window locking apparatus which prevents thewindowfrom being opened from the outside. "Thislockingapparatus is operatedau'to-v.

matically upon the lowering of the lower portion of the inner window sash, thus obviating the necessity of locking the window. 7 n

.Afurtherfeature of the present invention lies in the fact that the window sill is provided with a movable member which may be moved into en-, gagement with the outer window sash. This movable member is actuated by the closing of the lower sash .of the inner window, thus preventing a draftthrough the window due to a crack or space betweenjthe window sash and the sill.

A further feature Ofwthe present invention resides-in-the fact that the sash may, if desired, contain a plurality of panes of transparent material, thus increasing the insulating eiTect. If it is-so desired, a shee-t-of somewhat flexible glass or plastic maybe inserted in a groove extending about the awi'ndow pane opening of each sash, thus providing adouble window effect. In such a construction, the frame is provided with a fixed integral shoulder-externally of the window pane in which the'groove for the extra pane is provided. Theseand other objects and noveljeatures of myinventionflwill be more clearly and fully set forth in the following specification and claims. I in the drawings forming a part of my specificationz', f" 1 1 Figure; 1- is a perspective view of a window frame-embodying the construction of my invention: Q

3 Figure 5 is a ,perspective. view .of a portion of the screen showing the manner in which the same issupp t d-m 7 i .cThe window A- includes a window frame H) which is generally similar to that-customarily employed. The: frame [0 includes ahead jamb H, side jambsl2, and a sill I3. A-window stop i4 extends vertically along each of the jambs E2 to provide -a .g-uide for themovement of the lower sash 15 of the inner window, The upper sash it) of the inner window'is guided ;in :its movement by aygroove- [1 in the parting stop I9 between the inner and outer windows. The groove I'l' extends only a portion of the entireheight of the window, allowing-the window to open for ventilation purposes; but'providing an opening too small for a person to climb through,

A guide for vertical sliding movement of the lower sash 20 of the outer window is provided by the parting stop I9 and the parting stop 2 I. The upper sash 22 of the outer window is held in place by a right angular guide strip 23 which extends across the top of the frame beneath the level of the head jamb II and extends to the bottom of the upper sash 22 in raised position of this sash.

By removing the window stops and parting stops 54, i and H arid he guide'stifi'pfflfthesill may be removed from the exterior o'f'the 'window for repair or replacement. The sill I3 is slidably supported between the side jambs l2 and between the inner sill stop and the bottom plateylB-isecured to the lower ends of the side lambs I2.

The inner window sashes l andIS "a're n gene eral similar to those usually {ourrd aflouble hung sash window. Each of these sashes in preferred form comprises a rectangular openframework in which is mounted the usual window pane. The windowpane 24' is -provided in the lower sash I5 andthe window pane 25' is provided in the upper window sash" I6. These two'sashes 'arezprovided' with complemehtaryabutm'eri ts :26 an'dfl'l which-provide a sealbe'tween the'se -windows. JI-he outer'sashes- 20 and 2'2 ='are=likewiseprovided with window "
