REMOVABLE wmnow sAsrr.

Application filed January 19, 1928. Serial No. 247,869.

My invention relates to a window casing and has particular reference to a W1IldOW,

casing adapted to hold a window sash in position upon a building and providing means whereby the window sash may be removed from the casing for washing the glass window panes and the like without'the necessity of performing this operation from the outside thereof.

Another and further object of my invention is the provision of a window casing from which the window sash can be swung out of the casing and into the room while suspended upon the usual cords or chains in the casing, so that ready access can be had to each side of the window pane from the inside ofthe room.

Another and further object of my invention is the provision of a window casing from which the sash can be removed at the bottom of the Window casino. which is simple and efiicient in operation and which is weathertight and proof against rain or snow being driven into the room around the edges of the window sash.

These and other objects of my invention will be better and more readily understood by reference to the accompanying sheets of drawings, and in whichner side of a window and casing embodying my invention;

Figure 2 is a vertical sectional view of one side of the window casing shown in Figure 1; i r

Figure 3 is a cross sectional View through one side of the window casing showing the retaining member positioned between the window sash; and

Figure 4: is a view similar to the View of Figure 3 with the window strip in depressed position and showing one of the sash out of the window casing, as indicated in dotted lines.

Referrlng now specifically to the drawings, and in which like reference characters refer to like parts throughout, the building wall 10 is shown which forms a part of the building at the side of and below the window opening, against which a hollow window frame Figure 1 is an elevational View of the in- 11 is positioned, preferably of metal, and which issubstantially. rectangular in cross section and has an extension 12 at one side thereof which extends around the side of the wall 10. The window frame 11 on the outer side thereof has a rectangular portion 13 formed integrally therewith, which extends outward and abuts against the side of the" outer Window facing 14. l The portion 13 extends inward beyond the edge of the window I sash and has a vertically extending channel'- 15 formed therein, the said channel having an; open side whieh extends toward the window' sash for the-purpose of receiving a portion of the sash, as will be more fully described herelnafter. r

The frame 11 has an inwardly projecting portion 16 which forms a channel in the frame 11 and extends longitudinally thereof, havin its open side towards the window sash, and is I adapted to receive a sash strip 17 which extends vertically of the frame 11 and in normal position retains the window sash in their "proper positions against lateral movement. The sash strip 17; has a pair of .75 members 18 and 19,'U-shaped in cross section, formed thereon and which form channels within which projecting ribs formed on the window sash are received. I

The sash strip 17 is a U-shaped member inso tegrally formed and shaped to conform to the channel formed at the inner side of the frame 11, and has a well 20 formed therein within Which is seated the'head 21 of a locking key 22 which extends into a hollow trunnion 23 i formed in the wall of the frame 11. The lockingkey 22 has an outwardly turned end 24 which fits into a slot 25 in the trunnion 23 in the normal outward position of the sash strip 17, andis adapted to be turned around the end of the trunnion 23 to holdthe sash strip 17 in its inner position free of the sash (Fig. i). A spring 26 is mounted around the trunnion 23 and the projectingportion of the frame 11 whichnormally forces the sash strip 171outward. The end'2 l of the key 22 engages. the trunnion 23 at the end of the slot25 and prevents thesash strip 17 from, being forced out too great a distance (Fig. 3.)

At the inner side of the window frame 11 is a pair of retaining strips, upper ends of which, 27 and 28, are permanently secured to the side of the window casing 11 by means of screws, bolts, or any other suitable fastening means. A pair of hinges 30, 30 are provided by means of which the lower ends 31 and 32 respectively, of the window strips, are hinged to the upper ends, these members being provided with fastening members 33, 33 which extend through the members 31 and 32, these members having knurled buttons turned end 35 which seats into openings 36 formed on the inner side of the casingll. Elongated openings 37 are provided through which the members 33 extend, these members being permanently secured to the strips 31 and 32-and :provid'e means whereby these hinged strips are removably attached to the window frame 11. The strip '31 is angularly formed with an inwardly extending portion 38 which is folded upon itself and is adapted to engage an outwardly extending rib 39 formed on the inner windowsash so that this sash is normally held in proper position in the casing 11.2 The strip 32 .is similarly formed withthe exception, of course, that it is adapted to be placed at the opposite side of the window, these strips being formed in right and left hand strips so as to properly fit around the window sash. p

An upper'sashyis provided which is made up of a pair of side members 40 and 41, an upper member 42 and a lower member A3. These members together with the side members :40 and 41 are preferably formed of metal and have suitable channels therein for receiving the usual glass window pane 44. The side member 40 issubstantial-ly rectangular cross section and has an inwardly projecting port-ion45 against which the window pane 44: is seated, with a triangular shaped member 46 being provided for holding the window pane in proper position in ing themetal upon itself, and which extendsthe frame.

thereof has the metalturrred upon itself anda rib portion 47 formed thereon, this ;portion The member 40 at the outer side 47 projecting into the channel 15 formed in the casing 11, thus forming'a water-tight .joi nt and providing-a gui'dew'ay for the members? and holding thesas'hsecurely in position. At theopposite side of the member 40' a projectingrib portion 48 is formed by fold into the outer U-shaiped channel portion 18 of the member 17, so that the' sash, when the sash strip 17 is in its outer position, is held in proper position and moves up and down in the channels 15 and 18. The lower sash is composed of a pair of side members '49 and 50 with an upper member 51 and a lower member 52, the member i9 havingan outs wardlyprojectin'g portion 53-thereon adapted to engage against-the'side of the lower window panett withatriangularshaped member 55 being provided to hold the pane 54 in position. A rib portion 56 is formed on one of the outer corners of the member 49, which fits cooperating strips 138 and 59 are placed bep 34 on the outer ends thereof and an inwardly tween the members 43 and 51 which serve to close the openings between these sash and make "a tight fitting oint therebetween. It will be understood that the construction heretofore' described, applies equally well to the opposite sideof the sash with the exception that the channels and engaging members are formed in a different direction so as to conform to the necessaryrequirements at the opposite side of the window casing. Apair of sash weights 60 and 61 are shown which are suspended upon ropes orchains, which pass over pulleys mounted in the window frame in the usual manner, and are secured to the upper and lower window sash frames in the usual manner. I

When placing the sash in the window frames, the-sash strips 17 are depressed in the channel formed in the window frame and locked in this position by the locking keys 22. The upper sash is thereupon placed in position, after having the cords or chains secured thereto, in the frame 11 so the projecting .portion 47 engages in the channel 15. This sash is then lifted into position at the upper part of the frame 11. The lower sash is then placed in position, andthe hinged strips 31 and 32 locked in place by the locking members 33. This sash is thereupon lifted and the locking member 22 released thereby causing the springs 26 to force the sash strip outward thereby engaging the ribs 48 and 66in the upper and lower sash respectively, *and holding them in position in the frame 11. In removing the sash for cleaning purposes the reverse operation is performed thus releasing the-sash and allowing them to be swung into the room for cleaning the glass panes, or for any other purpose.

While I have described :more or less precisely the details of construction, 1 do not wish to be understood as limiting :myself thereto, as I contemplate changes in form and the proportion of parts and :the'substitution ofequiva-lents, as circumstances may suggest or render expedient without departing from the 'spiritor scope of myinvention.
