Still further, the invention proposes a window as aforesaidhavingweather stripping.

Still further, it is proposed to provide a sash for a window; including windowsof the 'aforementioned type provided with a spring counterbalance on one side and a. pulley counterbalance or'brake on-the, other side.

Still further; it is proposed to provide a. window with an automatically operable screen which screens any opening-of-the; window.

Afurther objectzof thepresent invention .is to provide a window having two sashes, one of which is provided With means wiping and sealing against the other sash.

A further objectis toprovidea'window having two vertically slidable sashes arranged so that they may also be pivotally swung toopan or closed position throughout a range of Vertical positions of the sashes, each sash coacting with a screen roller toscreen anyportionof the window opened by eithersash, one of the sashes having means for wiping the glass of the other of the sashes, and for sealing the space between the sashes against the entrance of insects and dust, both of said sashes being counterbalanced on one side by a spring counterbalance and on the other side by a double pulley arrangement.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be hadto the following description and accompanying drawings, and to the appended claims in which the various novel features of the inventionare more particularly set forth.

Fig. 14 is. afragmentary perspective view of two portions of one'of'the sashes pivoted at ninety degreesrelative to each other.

Fig. 15 is a front view of awindow, with the lower sash raisedshowing the screen'in operative position. v

Fig. 16 is a fragmentary-perspective viewof the window with the lowersash swung open.

The window, according *to this invention, comprises a frame lowhichisa-largely conventional I structure including asilll I. atop face board I2, a left face boardv I3, a right face boa1'dyl'4,'abottom faceboard 'l5, .a left inside board IS, a right inside board H, a top inside-board l8 anda bottom inside board [9. The inside of the Window is shown. in Fig. 1. The outside would be somewhat similar' in appearance in accordance with usual practice in making window frames out of wood. That is to say, substantially the same face boards would be provided on-the outside of the frameas on the inside.

Upper andlower sashguides wand 2| respectively are formed'by an inside guide strip 22, an intermediate guide strip 23 formedin two pieces connected together by screws, and an outside strip 24, allsecuredto-the boards f6 and I! on opposite sides of the window in the-usual manner. An upper sash 2'5 slides in guides 20 and a lower sash 26 slidesin-guides 21.

The two sashes are substantialljyidentical in structure and thereforeonly the bottom sash will be described in detail, corresponding parts of the top sash being indi'catedby like references with an accent added andreferred to only when it is deemed. necessary to clarify the following description. The sash includes a left (viewing from the inside of the window as in Fig. 1) slide strip 21 and a right slide, strip 28, the-cross sectional shape of the wood from which the strips are made being clearly shown in Figs; '2 and 3. A glass-containing frame 2'9,'which is similar to a conventional sash in many respects is pivotally secured to the two strips?! .28 by twooppo sitely disposed screws 30 adjacent the bottom of the sash. Strips 2'! and 28 are wider than

strips

22 and 24 so that the frame 29 is not concealed at all by

strips

22 and 24, leaving frame 29 free to pivot.

Strips

21 and 28 enable the sash to slide vertically in the manner of any ordinary window sash and the screws 3!! permit the frame 29 to pivot relative to the strips 2'! and 28 at any position that strips El and 28 may be slid to. This enables the frame 28 to be swung open for cleaning the glass or for ventilation, as shown in Fig. 16. The same is true, of course, of the top sash. However, the present invention is applicable to a single sash, or to a single sliding sash, window, as will be obvious.

Guides

21 and 28 each have a longitudinal shoulder 3| coacting with a corresponding shoulder 32 on the frame 29 permitting the frame 29 to swing in one direction (inward) to open position only and forming an airtight joint when the frame 29 is closed, airtight being used in the sense that ordinary windows are airtight when they are closed. Suitable means (not shown) may be provided for locking the glass-carrying frame to the

strips

21 and 28 to act as a unit therewith if desired. Also the usual latch (not shown) will be provided for locking the two sashes together. A weather strip 33 is fastened by screws to strip 24 and fits in a slot 3d in the upper window strip 2?. A similar Weatherstrip 33' is fastened by screws to strip 23 and fits in a slot 35 in strip 27. These are clearly shown in Fig. 2. Similar weatherstrips will be employed at the other side of the window, these strips not being shown in the drawings for simplicity.

The bottom part of the lower glass frame 25 is weatherstripped by a strip 38 coacting with a groove 31, best shown in Fig. 4.

The window as thus far described provides an upper and lower slidable sash, each of which is weatherstripped and each of which can be pivotally swung to open position as well as slid to open position.

A chamber 38 is provided on top of sill H and a chamber 38' is provided below board I8, these chambers being formed by suitable boards secured to the frame to box off the desired area and are covered by removable slide strips 38 which permits the interchanging of the rollers 39, all as is clearly shown in Fig, 4. A screen roller 39 is disposed in each of these chambers, each screen roller being wider than the adjacent frame 29 or 29' as will presently appear. The roller per se, detached from the window, is shown in Fig. 5. It includes a base 40 which ma be secured to the appropriate portion of the window frame, end members 4| extending from the base ends in which is journalled a spring-actuated roller 42 similar to an ordinary window shade roller. No further description thereof being deemed necessary since their construction is generally known by those skilled in the art, a roll of wire screen 43 being fastened to the roller and wound thereon. The side edges of the wire screen are bound by tape 44 to provide for easy sliding as Will presently appear and the top edge of the screen is secured to a strip 45 having wings 46 at either end. Two felt strips each having an orifice 48, are secured to the strip 45 at the same side as the screen. Each of these strips il ex tends around the edge of the strip 45 to the other side and over this other side, extending beyond the other edge thereof as is clearly shown in Fig. 5. Thus the screen, which is secured to the top of the strip 45, pulls in one direction from the 4 top of the strip whereas the strips 4'! pull in the opposite direction from the bottom of the strip, tending to turn it. The effect of this action is to tilt the strip 45 as shown in Figs. 7 and 8 for a purpose presently to appear.

Each of the rollers 39 is long enough so that the screen 33 extends the full width of the adjacent sash and therebeyond so that the taped ends of the wire and the wings 46 slide in slots 4f! formed in the bottom half of strips 22. The top screen for the top sash similarly slides in slots 49 in strip 23.

The bottom board of the frame 29 is provided with two hooks 56 on its inside face. When the strips 41, by means of the orifices 48, are hooked to the hooks 53, the screen will automatically follow the lower sash 26 when it is raised, therefore screening the open window against entrance of insects. Of course the screen can also be raised and lowered independently of the sash if desired, or it may be left rolled up, as in winter. The upper screen acts in a similar manner. The wings it are tilted in an inclined position in the slots 49, as shown in Fig. 8, thereby resting against opposite sides of the slots 49 and sealing the slots against the entrance of insects or of dust and other foreign matter around the ends of the wings.

Base Ml has a slot 5| in which is disposed a felt strip 52 which rubs against the wire screen as shown in Fig. 5, preventing passage of insects or foreign matter between the screen and the base as the screen is rolled or unrolled.

Another feature of the window of the present invention is that a strip 53 is secured to the lower edge of the top sash and rubs against the glass of the bottom sash at the outside (see Fig. 4) thereof, and against the adjacent wood sides, for wiping this glass, and wood sides as the sashes are moved relative to each other and for sealing the space between the sashes against the passage of insects or foreign matter into the space between the sashes when either or both are open. Strip 53 is formed of a slotted base 54 and a felt insert 55, best shown in Figs. 9 and 10, and is cut away at the ends to fit around the wood of frame 29.

The two sashes of the window are counterbalanced in a novel manner. A spring counterbalance 56 is secured to the board I! at the top of the upper sash, its flexible cable being secured to the top of the bottom sash. Similarly another spring counterbalance, identical with the counterbalance 56, but not shown in the drawing, is secured immediately behind the counterbalance 56 and secured to the top of the top sash. These counter-balances are of well known construction and no detailed description thereof is deemed necessary. One is shown per se in Fig. 11. However, such counterb-alances are not provided on the left side of the sashes. Each sash is counterbalanced on its left side by a double pulley arrangement, as follows:

Strips

21 and 21 at the left side of the sashes are each provided at its middle and in the outer face thereof with a recess 51 in which is disposed a pulley 58 having a spool 59 formed with adja cent tracks 66. The pulley is rotatively secured to the strip 2? (or 21) by a screw 61. A slot 62 is formed in one side of the strip above the pulley and a slot 63 is formed in the other side of the strip below the pulley. Cables 64 each have one end secured in one of said tracks and wound in their respective tracks, each in an opposite direction so that when the pulley turns in one direction or the other one cable will be unwound while the other cable is woundon the spool 60 and one extends therefrom through the slot 62 and the other extends through the other slot 63, one cable has its free end secured to the top of the window frame and the other has its free ends secured to the bottom of the window frame.

The counterbalance system operates as follows:

Considering the lower sash by way of example, it being understood that the upper sash operates in a similar manner, when the lower sash is raised, the spring counterbalance 56 winds up aiding in the raising of the lower sash. However, as there is a spring counterbalance 56 at only one side of the sash. if this were all that was provided the sash would not raise evenly but would bind in the frame. Also, the spring counterbalance would pull the sash all the way up and there would be no way to hold the sash in any desired partial window-opening position. However, the cables 64 provide for this, At the same time that the spring counterbalance winds up, one cable 64 is wound up on the spool in its track while the other cable 64 is unwound from the spool in its track. There is no tendency of either cable to wind or unwind by itself and therefore both cables, due to their inherent action and to friction, resist the pull of the spring counterbalance and counteract its tilting and raising eifect to the extent desired to hold the sash in any desired position and to keep the sash square in the frame, while nevertheless permitting the sash to be easily raised and lowered. This counterbalance arrangement does away with the well known type of counterbalance sash weight and all of its accompanying difilculties such as the breaking of sash cords and the taking apart of the window frame to replace them. The cable 64 is made of woven steel and is flexible and strong, insuring long life. However, should it break, it is only necessary to remove the sash from the window to replace it and not to take part of the frame apart,

From the foregoing description it will be seen that the present invention provides a novel window having many desirable characteristics not present in ordinary every day window construction. In a simple construction a window is provided having two vertically slidable sashes, each of which can pivot to open position at any vertical position that it is in, the sashes being weather: stripped and counterbalanced by a simple and compact arrangement. Furthermore the window includes as a part thereof screens for both the top and bottom sashes which screens are concealed from sight when not in use and may be hooked to the sashes for automatic operation when desired, thus doing away with separate screens which must be stored in winter. The window has many other useful features as were previously set forth. It will be obvious that the many advantageous characteristics of the window described have application to other types of windows than two sash windows, many of these features being adaptable equally as well to a single sash window.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. A window comprising a. frame having a compartment at one end, an actuable roller disposed in said compartment, a roll of wire screen wound on and secured to said roller, a strip secured to the free end of said screen, said wire screen being secured to said strip on one side thereof adjacent the edge thereof remote from said roller, two tabs secured to said strip adjacent the other edge thereof, and extending upwardly beyond said first mentioned edge on the other side of said strip, said strip having wings at its ends and said frame having slots in which said wings are adapted to slide, said wings being wider than said slots facilitating tilting of said wings to bear against opposite sides of said slot, a sash slidably disposed in said frame, and means for securing said tabs to said sash for winding and unwinding of said screen with movement of said sash.

2. A window comprising a frame having a compartment at one end, an actuable roller disposed in said compartment, a roll of wire screen wound on and secured to said roller, a'strip secured to the free end of said screen, said wire screen being secured to said strip on one side thereof adjacent the edge thereof remote from said roller, two tabs secured to said strip adjacent the other edge thereof, and extending upwardly beyond said first mentioned edge on the other side of said strip, said strip having wings at its ends and said frame having slots in which said wings are adapted to slide, said wings being wider than said slots, and being tiltable therein to bear against opposite sides of said slot, a sash slidably disposed in said frame, and means for securing said tabs to said sash for winding and unwinding of said screen with movement of said sash, said attachment of said tabs inwards of the free edge thereof insuring tilting of said strip engaging the wings against the sides of the slot when the sash is moved.

3. A window comprising a frame having a compartment at one end and slots at the sides thereof and slidably supporting sash, an actuable roller disposed in said compartment, a roll of wire screen wound on and secured to said roller and adapted to have sides guided by said slots when extended from said compartment, a strip secured to the free end of said screen and having wings engaging said slots, and means connecting said strip to said sash to extend said screen from said compartment when said sash is moved to an open position and simultaneously tilt said strips to cause its wings to bear against opposite sides of said slots in all extended positions of said screen.
