1 Claim. 1

Our present invention relates generally to windows, and more particularly to an auxiliary window construction embodying an interchangeable storm and screen sash which may be installed or removed from within, and which may be interengaged with the building frame and assembled together in an air-tight association.

In prior combination windows of this general type, many difficulties have arisen due to the obldow unit which obviates the above and other objections and combines the qualities of strength,

long life, easy installation, smooth operation, airtightness, and attractive appearance, as well as eliminating such burdens as heavy lifting, sticking, and dirt-trapping.

Another feature of our invention pertains to the novel and enicient channel strip construction with our novel locking, sealing, and holding flange, and reinforcing sliding edge element for housing the interchangeable storm and screen sashes and for adjustable attachment to the building window frame so that our combination window can be partly housed in such frame as to be unobtrusive and, in effect, constituting a weather-stripping construction, and an ornamental feature;

A further feature of our invention resides in 1 the provision of unique means for locking the sashes tightly with the windowsill, after such sashes have been installed, yet permitting ready and easy removal when so desired.

A still further object of our invention is to provide means to hold the upper sash from sliding downwardly while the lower sash is being removed, thus facilitating removal and preventing injury to the operator.

Further advantages, features, and details of construction will be hereinafter more fully pointed out and claimed.

Referring to the drawings showing a preferred embodiment of our invention:

Fig. 1 is a front elevational view showing our combination window in installed position;

Fig. 2 is an enlarged cross-sectional view on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged cross-sectional view on the line 3-3 of Fig. 1;

Fig. 4 is an enlarged cross-sectional view, similar to Fig. 3, showing a lower sash partly removed; and

Fig. 5 is an enlarged cross-sectional view on the line 5 5 of Fig. 1.

In the drawings, a building window frame of conventional design is shown, having like side sections IIl-I, connecting top section II, and-a bottom sill I2. Adapted for association with each side IEI' throughout the length thereof and with the top I I between said sides is our novel channel strip, preferably stamped out of a sheet of aluminum or other suitable rust-proof material, and bent into desired shape as clearly shown in Fig. 5, comprising a bottom portion I4, a doubly reinforced outer side arm I5 extending at right angles vto said portion I4, the outer fold of which portion I5 projects inwardly at approximately a forty-live degree angle to effect a flange I6, which, in turn, is formed with an attaching surface I1. For purposes of identification, we have designated each side-channel strip generally as I3, and the channel strip across the top as I 8.

A doubly reinforced inner side arm I9 parallels the outer side arm I5 throughout the entire top channel I8 and throughout substantially the upper half of each side-channel I3; but along the lower half of each channel I3 to permit ready-installation and removal of sashes adapted to slide` therein, said inner arm I9 is clinched laterally against the bottom portion I4, as clearly shown in Fig. 2. I

The channels I3 and I8 are secured to the side frames IQ-Iii and top II by anysuitable means, such as a plurality of screws 2U driven thru the attaching surface I'I. In this connection, it will be apparent that our novel channel strips I3 and I8 may be fastened to each frame III and top II, as shown, with the bottom I4 iiush therewith or removed slightly therefrom and with shims or the like therebetween, when adjustments are necessary to compensate for dimensional irregularities frequently encountered in building frame construction.

It will also .be apparent from the novel design of the iiange I6 and its attaching surface I'I that our channel strips I3 and I8 are enabled to be partially housed within the exterior limits of the frames III-4I), thus not only eliminating the bulky outside projections often prevalent in existing combination windows, but also, particularly in View of the detailed bevel arrangement of said flange I6, in effect adding an attractive appearance to the whole building.

It is believed that our unique channel construction is a distinct improvement in this art, and

accordingly we wish to claim the same herein broadly.

suitably secured in the bottom portion of the top channel I8 are one or more leaf springs 22-22 adapted to exert tension against the top frame 24 of an upper sash unit 23 when lifted into position, as shown in Fig. 3. We have shown the unit 23 as being of the standard type having said top frame 24, grooved bottom frame 25, and side frames 26-26 of proper dimensions to slide in the channels i3-i3, such four frame members enclosing a usual glass pane 21.

A lower sash unit 28 is provided having sid frames 29-29, grooved bottom frame 3H and top frame 3| formed with s, tongue 32 to t into said grooved frame 25 in weather-tight association, said frames, in turn, supporting as shown a glass pane 34 or, if desired, a Ventilating screen. Positioned below said grooved frame 30 and cooperating therewith in weather-tight relation by means ofthe tongue 33 is a toggle apron 35, the lower surface of said apron 35 designed to rest Vupon the window sill l2 and form a tight joint therewith.

Losely mounted on the sill I2 and secured thereto by loops 35-38 are a pair of combination brackets 31h-3l which are positioned adjacent to and adapted to cooperate with said apron 35, functioning in the capacity of a spring clip or catch 38 when swung into the position shown in Fig'. 3, and acting as an apron support 39 when swung into the position shown in Fig. 4.

To facilitate Vthe installation and removal of the lower sash 28, we preferably attach by means of screws 4l a pair of finger-hooks 40--40 to the bottoni frame 30, thus `prmfidirag an operator with suitable lifting and pulling means for both purposes.

In order to hold 'the upper sash and window 'from dropping down entirely when the lower sash is swung outwardly and removed, we provide any suitable catch in position as indicated at 50, Fig. 1, to catch the upper sash` whenit is dropped slightly because of its weight and the expansive action of the springs 22 during the removal `of Athe lower sash.

For this purpose, a spring-pressed plunger may be' tted, as Shown at 50, to Vproject in the path ci the upper sash as the lower une is removed, or any other suitable catch can be manually compressed when it is desired to lower the upper sash completely 'and swing it inwardly for Ywashing, removal, or replacing.

The important feature of our construction, utilizing the toggle apron 35 together with the advantages incident to our novel form of channel,

which is, in effect, a. combined channel and weather-stripping element, will be readily appreciated. With the apron 35 swung inwardly and resting on the bevelled surface of the catch 39, the lower window or screen can be easily adjusted with the tongue 32 in the corresponding groove in the upper sash, and with the bottom portion tting on the top surface of the tongue 33 in the apron 35. Thereupon, a slight pressure inwardly lifts both window frames against their own Weight and the tension of the springs 22 by the toggleaction provided by our construction, thereby firmly forcing both sashes and toggle apron in contact and alignment with the respective channels on each side, thereby holds all members under tension of the springs 22 in the topmost channel. Thus the operator is relieved of the exertion of lifting the sashes, Aboth upper and lower, and forcing the same to slide in the channels since the simple toggle action aiorded by the pushing in of the bottom sash does the lifting automatically.

We claim:

Interchangeable glass and screen construction of the kind described for association with a building Window frame, comprising upper and lower sashes, U-shaped side channels in which the edge portion of said sashes may slide, the lower part of one ilange of said U -shaped channel being omitted, said channels being constructed .and

arranged to be partly housed within the building window frame, and with an integral angularly extending bracing flange adapted to be attached outside said window frame, spring means in the top channel strip, a toggle apron positioned on the sill of said window frame and having interlocking means with the lower sash, swinging catches formed with a predetermined angle on which the toggle apron may rest in position Vto engage said interlocking means between the toggle and the lower sash, whereby swinging of the lower sash and toggle into vertical alignnient will raise both sash and toggle into springtensioned engagement with the spring means in the top channel.
