WINDOW-PROTECTING ATTACHMENT.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed October 1, 1915. Serial No. 53,604.

.. To all whom it may concern:

Be it known that I, STERRETT E. MoNUL'rY, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Window-Protecting Attachmerits, of which the following is a specification.

This invention relates to improvements in means. for preventing the ingress of flies, insects and obnoxious substances through Windows in which fly screens have been arranged, and the invention is specifically designed to close the gap between the screen frame and the window sash, and to permit of the adjustment of the window sash.

When one of the common fly screen frames is positioned in a window casing and the inner window sash raised, it is possible for flies or other insects to enter the room through the gap formed between the opposing sides of the inner sash and the screen frame. The clearance between the sash and the screen frame is made freer by the partial lowering of the inner sash.

My invention provides simple means for closing the gap between the screen frame and the inner sash frame, and is so constructed as to permit of the ready adjust ment-of the inner sash frame. The invention is embodied in a frame for holding a yieldable strip, which frame is provided with end members adapted to engage the parting strips of the window casing and adjustable relative to the strip holding frame, and detachable relative to the parting strips.

l/Vith the above and other objects in view the invention consists of certain new and useful constructions, combinations and arrangeinents of parts, 'clearly described in the following specification and fully illus-v trated in the accompanying drawings, in which Figure 1 is a vertical sectional view of a window casing and companion window sashes, showing the improved device in operative position.

Fig. 2 is a side view of the improved device.

Fig. 3 is atop plan view thereof.

Fig. 4 is a detail endview, partly in section, and on an enlarged scale, showing one of the connecting members or legs, and the key-hole slot.

Fig. 5 is a similar view, showing the opposite side.

Fig. 6 is a side elevation of a modifiec form.

Fig. 7 is a detail plan view of end portions of the members of the modified form. Fig. 8 is a transverse sectional view of another modified form.

Fig. 9 is a planview thereof.

Fig. 9* is a detail end view of a supporting leg.

Fig. 9 is a similar view of another supporting leg.

Fig. 9 is a detail sectional view of a. clamping tongue construction.

Referring to the accompanying drawings 5 designates the lower member or sill of the window casing, 6 and 7 the parting strips, 8 the inner sash frame, 9 the outer sash frame, and 10 and 11 the inner and outer sash guiding strips, respectively.

The usual screen frame 12 is positioned be.- tween the outer guiding strips 11 and the parting strips 6 and 7. When the inner sash frame 8 is in the position shown in Fig. 1, that is with its lower member below the upper horizontal member of the screen frame, a gap or clearance will be. opened through which flies or other insects may gain admission to the room.

To prevent flies and other insects from entering the space between the-inner window sash and the screen frame, I arrange a flexible strip 14 on a holding frame 15, and secure the ends of this holding frame to the'parting strips 6 and 7 so that the flexible. strip 14 will lie in a horizontal plane and its outer edges will project beyond the vertical plane of the window glass sections of the inner and outer sash frames.

The flexible strip holding frame 15 consists of a lower bar member 16, an intermediate top bar member 17, and oppositely extending upper end bar members 18 and 19, each of which is formed with a pendant leg or attaching member 20. The bars 16, 17, 18 and 19 are formed of strip stock and are each provided with angular longitudinal flanges F, located on opposite sides thereof, whereby the bar is substantially U-shaped in cross section. The flanges F of the lower bar 16 project downwardly, and the flanges F of the upper bars 17, 18 and 19 project upwardly. The pendant legs or attaching members 20 are formed on the bars 18 and 19 by bending the end portions of said bars,

without flattening the flanges of said endportions. In this way each leg or attaching member 20 is provided with spaced flanges f and in the space thus provided in each leg one of the parting strips is adapted to snugly fit.

Each leg or attaching member 20 is formed with an opening 21, which may be a circular opening, but which is preferably a key-hole opening, with its larger end portion 21 located near the lower terminal of the leg. The frame 15 is supported on the parting strips 6 and 7 by means of screws, brads or other headed fastening means, 22, the heads of which are smaller than the portions 21 of the leg openings 21, and the shanks of which are smaller than the portions 21 of saidleg openings 21. By placing the larger endportions 21 of said leg.

openings 21 in registration. with the heads of the fasteners 22 and forcing the legs against the partingstrips and then forcing the legs downwardlysothat the shanks of the fasteners will enter the smaller portions of theleg openings the holding frame may be secured to the parting strips. By reversing, this action the, holding frame 15 may be readily detached from the parting strips.v

The flexible strip 14; is preferably a thin rubber strip, suitably reinforced by canvas, but it may consist of felt, canvas or other material. This strip 14. is secured between the lower bar 16 and the upper bars 17, 18 and19 by means of screws or fasteners 23 and 241. The screws or fasteners 23 project through openings formed in the intermediate bar 17 and the lower bar 16, and the screws or fasteners 24 project through longitudinal slots. 25 formed in the bars 18 and 19 and then through the lower bar 16. The screws or fasteners 23 and 24 are each provided with, a nut. or clamping. member 26, and by tightening said nuts or clamping members 26 on the screws or fasteners 23 and-,2 1-the upper and lower. bars may be rigidly lockedto each other andthe flexible strip tightly secured between said. upper andlower bars. By adjusting the relation The flexible strip 14 is considerably wider than the bars or the holding frame, so that it will project laterally of the holding frame a suflicient distance to contact with the glass sections of the window sashes, and thus prevent the passage of flies or other insects.

By the use of the intermediate bar and the method of rigidly connecting the intermediate bar to the lower bar, a rigid central body is provided for the holding frame.

In Figs. 6 and 7 I show a modified form of the invention, wherein the holding frame is made up of a single lower bar 27 and a single upper bar 28, each bar being formed with. a pendant leg or: attaching member 29, and being also formed with a longitudinal. slot 30 for each clamping screw or device, by means of which the upper and lower bars are clamped to each other. and theflexible. strip 32 clamped between the bars, in the manner previously set forth. The flexible strip is also formed with longitudinal slotsadapted to register with the longitudinal slots of the bars 27 and 28, so that the necessary relative longitudinal adjustment between the bars 27 and 28 can.

be effected against the flexible strip.

In Figs. 8 and 9 I show a modified form of construction, wherein the slot and bolt adjustment is eliminated, by the use of: two bars, one of Wl11Cl1 slides within the other.

Referring to these figures l35 designates the.

lower bar, which'is' formed with. overlying inset flanges 35 and 35 theinner edges of.

which arespacedapart, so that the bar 35-is substantially C-shapedin cross section. The

bar 35 receives the side wings 36 and 36 of the upperbar 36, Wl11Cl1 is providedwith a central offset portion 36 which is adapted toslide between the opposing edges of the inset flanges 35 and-35". sertedendwise in the bar. 35 and is adapted toslide without limit therein, so that the The bar 36 is in-- two bars, when interfltted, maybe extended the connecting rivets 39. Against the lower side of the holding frame bar .35 the flexible strip 40 is disposed, being clamped to the bar, 35 by the plate 41 and the connecting rivets 4L2. The plates 38and 4C1 are preferably transversely curved, so as to dish or curve .thefleXible strips 37'and 40. The upper face of the bar 36 and the lower face of the bar35 may also be curved, as shown in cross section in Fig. 8. i

To retain the screen against outward ;displacement I provide bracket members or stops 43, which are secured to the plate 38 by the rivets 39, and which have pendant screen engaging arms 4% pro ecting outwardly of the strips 37 and 40.

Owing to the deflection of the strips 37 and 40 toward each other, the confronting edges of the strips will contact with each other, as shown in Fig. 8, so that there will be no space left between the strips.

The flexible strip 37 frictionally resists the free sliding action of the bars 35 and 36 on each other, by its engagement with the upper faces of the inset flanges 35 and 35 and by its engagement with the flexible strip 40.

The bar 35 is formed with a terminal leg 45, which is provided with a keyhole opening 45*; and the bar 36 is formed with a terminal leg 46, which is provided with a keyhole opening 46*, as shown in Figs. 9 and 9", respectively.

The manner in which the flexible strip is secured to the bar 36, and the clamping bar 38 secured to said bar 36, is shown in Fig. 9; a similar construction being carried out with reference to bar 35. The bar 38 is formed with a tongue 38 which is extended through a small opening 36 formed in the bar 36 and a small opening 37 formed in the strip 37 and is then bent against the face of the bar 36, thus locking the bars 36 and 38 to each other and the flexible strip therebetween.
