STEPHEN M. CASEY BY Wmv 7M y ATTORNEYS I5a are imbedded in the wood I5 at appropriate points to hold the glass in place, and the adjacent reinforcing edges at the sides and upper and lower ends of the sash are held together by rivets` I9` which pass through the reinforcing edges I6 and also through metal corner strips 2| disposed at the corners of the sash. The sidey reinforcing strips IB arearranged tol fit within channelfshaped guide members I 3` which eX- tend vvertically of theframe and provide slide- Ways 22 and 23 for th'ewupper and lower sashes, re'- spectively. It willbe understood that the reinforcing member I.6 and slideways 22 and 23 are: complementary infshape and are dimensioned' so that the `sash may easily be slid vertically with respect to 'the frame, but, nevertheless, a

48 disposed on the outside of the window which prevents water from leaking under the frame. The slide mounting members 36 and the top and bottom mounting members 46' and 4l areV held together by slot-and-pin connections. Thus, a yoke 49 is riveted to the lower mounting member 41 as best shown in Fig. '7, saidmember 49 beingslidably received within the channelfshapel side mountingwmember 36. An elongated'pinSI passes through `apertures in each of the legs" 52 of theyoke-sha'ped member 49 and extends through horizontal slots 53 in the lower end ofthe side mounting member 36. Yoke-shaped member 49, bottom mounting member 41A and the outwardly-bent flange 50 of frame i3 arev all fixed in position by rivets 55 substantially Vweather-tight' t isf obtained.

` vVertical guide members I3 are formed substantially `Eshaped in .cross-section as shown par-i" ticularly in Figs. 2, 3 and 4. The upper sash II maybe disposedwithin the channel 22 andthe lower sash I2 disposed within the otherchannel of the E-shaped gui'defmember I3. Thus, the upper -and lower sash .maybe individually raised ,orf lowered by handhwithourl iint'erference one with the other and thereby the degree of venti lation through the window construction may''be controlled;` e

It lwill`- be understood that ia plurality` of notches k29 may be cutout of the y"side-guide members I3, said notches receiving spring biased latch members .3V-carriedby the reinforcing edges I6 of the sash. This'construction' resembles that shown irl my'P-atent No. 2,288,936. IThe sashr may be held in various positions-of adjustvment by permitting the latchimembers -3I` to enf gage the notches 29, whereupon the sash will-be heldin position until the latch" members fare manually retracted by manipulation-ofr nger grips 32 connected to said latches and the sash raised or lowered to' -a new ment.

`The side guide members I3 are receivdwithposition of adjust- 'The' mounting member is heldin the door byv reasonrof4V the fact that the outer longitudinal surface of vathen basel 39 of! the side mounting member 36l isprovided withk a central longitudinaljrib 56 and-lesser: ribs 51 longitudinally extending along each corner. A conventional door panel is held in place by means of a pair of molding strips 58 which: are spaced apart to provide a. gap 59 havingthe .thickness of a wood panel or a piece of glass which may ordinarily `roccupyfa conventional door panel. The central rib 56 of the mounting member 36 is of a thicknessisubstantially equal to the width of said gap 59, i. e., of a wood panel or` glass pane and thus, the molding strips 58 hold said rib 56- in position as best: shown'in Figs. Zand Il.v The corner ribs I 5`I bear against said molding'strips 58 and as in the open ends ofsubstantially(Lllshaped channel mountingjrrlembers'v 36.r The-distance between thev parallel sides 3l ofv the mounting member 36 is substantially equal to the thickness ofthe side guide memberv I3, butvthe'side guide membersI3 are lsuiciently smaller so fthat they may slidev within' the mounting membe/rf'3v6 air and watertight. f f Substantially onelthirdrof the Way below the topand one-third of the-way` above the bottom of themounting member 36 is a spring 38,"s'u'bn but '.thevt is, close-enough so that the window; is

stantially helical in conguration, one-'end iof.

thespring being xedto the base 39 of mount'- in'g 36' and the other'fend bearing against'the guidev member I3L allV as most clearly shown=in Figs. 3 and 5. `The inner end of spring-38l is xed to base 39=by means of a rivet 4I passing through the base 39 and having 1a washer'54'2 at its opposite end which `engages one ofthe coils of spring 38.r The opposite end ofvthesprin'g'38 is free, but bears against the guide member' I3.

Thus, the spring urges the guide member I3 and mounting member 36 apart', but the'force ofthe spring 38 is weak enough so that thev guide mem- `36, thereby compressing the spring 38'.V The top mounting member 46k is formed. as a shallow channel extending'across the top oiv the window. The bottom mounting memberl'l .ber I3k may be readily slid within the channel VWhich'extends acrosspthe bottom of .the window issubstantially flat with an upwardly bent'Il-ange sistin holding the mountinginposition.

l Assuming that'a conventional'door I0 is to be tted vwithV a window construction which is the sub'jvectfvofv the present invention, the molding strips 58 at'the -topfand bottom of the panel are permanently removed. *Molding strips 58 at the sides areV temporarily removed to permit withdrawal of the glass or wood and then replaced. The workman manually; rcompresses the' side mounting members 36 toward each other so that the centralirib 56'ateach side may pass over the high points of the'l'molding strips 58"along the sides-ofthe panel. This-compression is made possible by reason of the r`=fact that the springs 38 compress` and the 'sfideE guide v,members I3 slide within" the channels which 'make up the'side mounting members 36; With the central rib 56 in position in gap 59 between the molding members 58 thesprings y33 snap the side mounting membersu36 inposition.' It will be understood that the top mounting member 46 ts snugly against the topl'of fthe panel opening vand' that thebottom mountingimember 4'I lits snuglyagainst the bottom of thepanelwIt will be observed, therefore, that the installation is' simple and requires no special tools or extraordinary skill. I

With the Window in position, as weatherv condi# tions require, the bottom and top half of the sash mayrbe raised Vorlowered toafford the required degree of'ventilation. Y

If it should be necessary to remove the entire window, as when the door is being painted or for any other purpose, the upper sash I6 is lowered halfway and the lower sash I2 is raised halfway so that two sashes overlie each other. The workman then grasps one of thev side mounting members 36 and pulls the same inwardly toward the center of the panel.` This operation compresses the opposite side guide member I3 inwardly into the channel of its side mounting member 36. Thereupon the central rib 56 of the rst side escapes from within the gap 59 between the molding strips 58 which hold it in place and thus the entire window may be lifted out of the door.

When it is necessary to remove only one sash, as when the pane of glass has been broken, the two sashes I I and I2 are moved to the-same position overlying one another as heretofore described, the sash I2 to be removed is grasped and moved sidewise, thereby compressing the opposite side guide member I3 into the open channel of the opposite side mounting member 36. This operation is continued until the reinforcing edge I6 escapes from the channel 23 of the guide member I3, and thereupon the sash I2 may be lifted out but the other sash I I and the entire mounting 36, 46, 41 and guide I3 are left in position.

, The ease and rapidity with which the window may be installed and removed or an individual sash installed and removed is one of the important features of the present invention. This feature has particular utility when the mounting, frame and reinforcement I6 are made of aluminum inasmuch as it is undesirable to paint such material. The ease with which the sashes II and I2 may be removed from the guide I3 makes it possible to transport the sash to a glazer for replacement of panes.

Although I have described my invention in some detail by wayof illumination for purposes of clarity of understanding, it is understood that certain changes and modications may be made therein without departing from the spirit of the invention or scope of the appended claims.

I claim:

1. A vertically-slidable, plural window sash construction for installation in an opening in a door, a door side frame member defining said opening of said door, at least two moldings on said door side frame member having a groove therebetween, said window construction comprising, a pair of substantially U-shaped channel mounting members disposed on opposite sides of said opening, each ofrsaid channel members having its open side facing toward the center of the door and having at least three ridges projecting upwardly from its opposite side, the intermediate ridge tting within said groove, a pair of sash side guide members, each of said sash guide members being slidably received in one of said channel members, each of said sash guide members being shaped as a double channel with the open sides facing toward the center of the door, resilient means biasing adjacent channel mounting members and sash guide members apart, means restraining said sash guide members within the openings of said channel mounting members, and a pair of vertically slidable window sashes, one of said sashes having its side edges received within one of the channels of said guide members and the other said side having its side edges received within the other of said channels, said sashesbeing slidable parallel to each other.

2. A window construction according to claim 1 which further comprises a top and a bottom horizontal mounting member fitting against the top and bottom edges of said opening, and slot-andpin connections connecting each end of each of said horizontal mounting members to one of said channel mounting members, one of said horizontal mounting members having longitudinal ribs.
