Y My invention consists in a, new and improved window structure, including a frame and sash slidingly mounted therein.

One of the objects of my invention is the provision of a window structure of frame and slidingsash which may be either installed in a window opening or installed in the usual window frame as for instance in connection with storm windows, from which the sash are usually removed in warm weather.

Another object is the provision of means for sustaining the sash in the frame at a selected elevation without the use of counterbalancing means such as cords and weights. Another object is the provision of mean for installing the sash in the frame and removing them therefrom quickly and conveniently and without the use of tools.

Another object is the provision of a Window structure in which the windows may be mounted to slide easily where the frame is out of true.

Other objects will appear from thefollowing description.

In the accompanying drawings, wherein is i1- lustrated a practical embodiment of the principles of the invention,

ing as illustrated in Fig. 1 is provided with the conventionalstationary window frame compris- '-'ing the sill In, the lintel H, and the vertical stiles l2.

Within the stationary frame there is installed,

'preferablyremovably, an inner window frame, I which-may be' formed conveniently of sheet metal,

andwhi-ch comprises a sill IS, a lintel i4 and the vertical auxiliary stiles i5.

r The sill i3 and the lintel [4 may be, as show in Figs. 3- and 4 respectively, of similar cross sectionalform but inversely disposed.

" Thus the sill I3 is provided along its top surface with a pair of parallel'vertical flanges extending longitudinally of the sill, the flange I6 "extending along the inner side of the sill and the flange i1 parallel with flange it but spaced therefrom'. When the lower sash l8 of the window is in its closed position, as indicated in Fig. 4, the outei v ertical surface of the bottom bar IQ of "thesash snugly engages the inner vertical face of the flange [6 while the flange I1 is telescoped from-above by the slot 20 formed in the lower facefof thesash bar I9, thus forming a weather rain the top wall of the sill l3 preferably is inclined downwardly from the flange I? to the outer edge of the sill.

The lintel} M of the inner frame is disposed in a position the reverse of that of the sill l3, the

flange IFbeing'at the outer side,'asil1ustrated in Fig. '3, and when the upper sash 2| is closed the face of the flange l6 fits against the vertical face of the top'bar 22 of the upper sash, while the I flange I'i engages a slot 23 in said bar, thus forma weather tight seal between the sash and the lintel.

rein-tenet to Figs. 5, 6 and 7, 24 indicates ."themeeting rail of the lower sash i8, and 25 the ne'eting railof thetop sash 2|. These rails are of "greaterthickness than the lower bar of the (I lower sash and the upper bar of the upper sash, thusbridging the space between the sash corresponding tothe combined width of the parting strip sections of the stile later to be described.

The lower portion of the outer face of the ,m eting rail Zi'is'cut away to form a recess 26 to provide clearance, when the sash are closed and ,the meeting rails are in their relative positions show'ninFig 5, for the inner extending troughj; like: extension 2 of the rail 25.

urged'outwardly to protrude from theopen fronts its upper portion to the inner face of rail 25 and depending within the trough of extension 21. while 29 indicates a like packing strip attached to the outer face of rail 24 and extending down within the reces so as to engage and nest in the packing strip 28 as shown in Fig. 5, when the sash are both in their closed position.

Adjacent each end of the sill l3 and of the lintel [4, the flanges l6 and H are omitted so that the ends of 'tlrersill and xlinte'l may be telesc'oped into the auxiliary stiles l5 andbe secured therein as by welding or riveting. Likewise the extra, width of the meeting rails of the lower and upper sash is reduced to the width of the bars s -|Q a;ng1' 22, to provide clearance for the parting stripsections, as indicated at 3B in FigsJSahfiW;

The auxiliary stiles 15 may -be-formed conven iently by bending up a strip of metal of the proper length and width to a rectangular cross sectional shape comprising a closed rear wall, parallel side walls and an open front.

The inner frame formed by thee-sill 13, the lintel l4 and the auxiliarystiles l5, connected =tgether at their extremities is of the properexterior dimensions as to fit in the aouter window frame or window opening, as the case may :be, and may be held in position by any convenient-means suchras resting. inwardly of theibuildingaagainst the vertical strips 3! secured tofaces of the stiles l2, as by means of the screws 32 extendingqfrom without through the spaced side walls of the auxiliary stiles l and driven into the strips ,-3l.

, Adjacent their outer vertical edges the side walls of the auxiliary stiles l5 are provided with internal shoulders or stops 33, which when the auxiliary stiles are formed'of sheetmetalnnaybe produced by folding themetal inwardly and backwardly against the'inner surfaces of the sidewalls as shown in Figs. 2 and'8.

34 indicates a metal bar mounted in the in- 'terior of each of the auxiliary stiles and extending longitudinally therein in front of the screws 32. The bars 34 are of T-cross sectional shape, the stem "35 of the T extendin'gtowariijthe open fronts of the auxiliary stiles, and t'hei'base of the stem being enlarged laterally t'offolf'm "a double stop 36. V

'31 indicates apair'o'f bars mounted in eachof the auxiliary stiles 15, one on eitherf'side 'of"'the vertical edge with nangesbs 'proje'e'tingiaterany flange 38 by engagement with thestop 3'3prevents accidental disassemblage of the parts relativeto 'theauxiliarystile.

The members 31 are elongated bars ext'enfding up through the auxiliary stiles, 'aniljthey are of 'theauxiliary stiles by 'averti'cal series of Tbo'wed 'leaf springs 39 riveted 'or'oth"erwise js'ecured at their centers to the front f ace of the b'ar BF-with their'e'nds bearing against the'backsdftlrefmembers 31.

The "front fedges "of the members- 31 areipro- 'videii centrall'y'witha verticalfbeadilqwhich engagejsjvertical slots 41 jin'tlie edgejfof *tlfesash,

"thus slidably supporting the sajslrin the frame. I

The members '31 are also provided with direct shoulders 42 which mate in pairs, as sliown jin Fig.2 to form a sectionalparting stri j 'tween the upper "and lower *sashfthe parting strlpf sec tionslTmovin-g inwardly andofltwar'dly'inmnisom 4 with the beads 40, both being portions of the corresponding members 31.

It is thus seen that the upper and lower sash are mounted for vertical sliding movement on either side of the sectional parting strips.

If desired, the sliding connection between the members 31 and the sash, instead of being a bead and groove, may be formed of arcuate or angular convex and concave surface of the member 31 and 't'he 'edge ofithe sashiaslin'dicated in Fig. 9.

FigfB illustrates the method of installing a sash,

in the illustration the lower sash l8, in the frame. The sash is first presented in the horizontally tilted-. position shown and one of its grooved edges,

the left in the view, is engaged with the bead 40 and=the= sashis then pushed to the left until the member 31 is caused to retreat sumciently into its auxiliary stile 'to'p'ermit the window to be swun inwardly to engage the groove dl on the right hand edge of the window with the bead on the corresponding-member (FL The leaf-springs at eithersidewill then automatically centei' the sash in position. In installing the sash, theupper ehsi fir tp tint ip t 1 The removal of -a sash .is accomplished by reversing the above-described operation, the sash lbeing first ,pushed in one direction .to retreat ,the corresponding member 3.! sufficiently .;to,. permit -the lothersedge of the-sash to .be released and the sash is then lifted out. In removing the-sash the :lower one is first removed.

The -forming of the p artingstrip of two-cooperating; sections,.-each moving with the member 31, renders the insertion of -a;sash into and-itsreemovalirom ,the frame much more' easyas there -is--n o-;chance of the sash jamming.;against:a stationary-yparting strip. I y
