conLArsIBLE WINDOW-SCREEN.

Specification of Letters Patent. Patented Jan. 9, 191'?.

Application filed June 24, 1915. Serial No. 36,089.

To all uwm t may concern Beit known that I, EDWARD T. Bunnowns, a citizen of the United States, residing at Portland7 in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Collapsible lVindow-Screens, of which the following is a specilication.

This invention relates to collapsible win-V dow screens of the general type shown in my prior applications, Serial No. 1310, iiled Jan. 9, 1915; Serial No. 2841, filed Jan. 18, 1915, and Serial No. 30,364, filed May 25, 1915. Thile such former applications relate to half-length screens, and means for supporting the same from the upper sash, the present invention contemplates the pro'- vision of improved means for supporting such screen independent of the sash, and also provision of a` full length screen having improved mea-ns for supportingl the same.

In order that the invention may be clearly understood, reference is had to the accomu panying drawings, forming part ofA this specification, and in which,

Figure 1 is a sectional perspective view of the outside of a window, showing my improved full length screen applied thereto; Fig. 2 is'an enlarged fragmentary section through the upper part of such a window showing the means for supporting the top bar of the screen; Fig. 3 is a horizontal section on an enlarged scale, substantially on the line 3--3 of Fig. 1; Fig. 4 is a. vertical section through a window showing one method of supporting al half-length screen independent of the sash; Fig. 5 is a fragmentary elevation of the supporting means shown in Fig. 4; and, Fig. 6 is a fraOinentary, enlarged, vertical section through the meeting rails of the two sashes, showing a different means for supporting a half-length screen.

Referring to the drawings in detail, 1 designates the window frame, 2 the lintel or outside trim, 3 the parting bead, 4 the blind stop, 5 the sill, and 6 and 7 the upper and lower sashes, respectively, all of which parts may be of the usual or any desired construction.

8 designates the runway in which the upper sash moves, and 9 indicates the screen material which, as in my prior applications above referred to, may consist of specially treated fibrous netting. Y

IThe upper bar in the present case is preferably of the shape shown in Fig. 2,-being substantially rectangular in cross section and having its upper edge somewhat-thinned. One end of the netting 9 is secured to the outside face of the bar 10,-as by means of a key or spline 10, in the usual manner. The lower end of the netting 9 is secured to and adapted to be wound around a bar or vroller 11, preferably circular in cross section. The bar 11 is adapted to rest on the sill 5 and may be held in position thereon by any of the severa-l means shown in my former applications. The ends of the bar are capable of sliding freely inthe runway 8, as shown in Fig. 3. Y l

12 designates the inner bead and 13 a strip which is secured to the edge of the blind stop 4 by means of nails 14. It will be noted thatthis strip 13 extends the full length'of the window frame, and that at its upper portion its outer edge is flush with the outer edge of the blind stop 4, as vclearly shown in Fig. 3. By reference to Fig. 4, it will be seen that the strip isY substantially straight from the top downward to a point opposite the meeting rails of the sashes, and from this point it is inclined inwardly until its lower end is flush withV the inside of the blind stop as shown. v The purpose of thus bringing in the lower end of the strip 13 isy to cause the edge ofthe netting 9, at the lower part of the screen, to lie snugly thereagainst, and this is necessary since the netting is secured to the bar 11 which lies in the runway 8. y

The upper end of the strip 13 is spaced as far outwardly as possible for the purpose of accommodating, between itself and the upper sash 6, the supporting means for the top bar 10 of the screen. The supporting means preferably consists of af plurality of resilient sheet meta-l clips 15, the number used depending upon the width of the window. Each ofA these clips has a flat middle portion which is secured to the trim or lintel 2, by means of a screw 16, or the like, and a pair of spaced arms, the outer arm 17 being the shorter. Such arm 17 is provided with an outwardly turned lower end. The other arm 18 is longer than the 'arm 17 and extends substantially straight down parallel with the edge of the blind stop, to a point somewhat below the end of arm 17. At lits lower end the arm 18 is provided with a retaining lug 19, preferably formed by bending the end of the arm so as to produce Ia hump. It will be understood that the space between the lug 19 and the end of the arm 17 is suiicient to permit the bar 10 being inserted edgewise into the clip and then slightly turned so that its lower edge rests upon and is supported by the lug 19. IThe thinned upper edge of the bar 10 facilitates its being inserted into the clips, and thc resilient pressure of the arm 17 serves to maintain the bar in snug contact with the arm 18 and lug 19. lt will be further seen that the arm 18 is backed by the sash 6 and therefore cannot yield.

ln the construction above described it will be observed that the supporting` means for the screen is wholly independent of either sash, and that either or both sashes may be raised or lowered as desired without interfering with the screen, and without leaving any opening through which insects may enter.

In Fig. 4, l have shown means by which a screen of this type may be supported at half-length. In this case the surplus netting is simply wound upon the bar 11. The bar 10 is of such thickness as to snugly fit between the sash 6 and the strip 13, as in the case of the full length screen, and this bar may be conveniently supported by means of a pair of semi-elliptic springs 20, secured to the window frame on each side and adapted to frictionally engage the ends of the bar 10. The springs 20 are secured to the window frame by means of nails or screws 21, such fastening devices being applied to one end only of the springs, the other end remaining free. These springs may be quite similar to those shownv in my prior application Serial No. 2841, above referred to, but are supported by the window frame instead of by the sash. ln the arrangement of Fig. 4, also, it will be noted that the screen supporting means is entirely independent of either sash.

ln Fig. 6, l have shown the upper bar 10 supported from the sash 6 by means of a device similar to that shown in my application Serial No. 30,364, above referred to. rlhis device consists of a hook comprising a screw shank 22 and an arm 23, extending at right angles thereto. Two or more such hooks are screwed 'into the bottom of sash 6 to the desired extent, and the arms 23 thereof turned so as to engage under the bar 10 and support the same, as will be obvious. In this case,

also, the bar 10 snugly lls the space between the strip 13 and sash 6 so as to make a tight joint.

l/Vhat l claim iS:

1. rEhe combination with a window frame having the usual sash, of a strip secured to a vertical face of the frame, a flexible screen, and a bar to which one end of said screen is secured mounted horizontally with its ends in and snugly fitting the space between such sash and strip, the side edges of said screen resting against the face of said strip.

2. The combination with a window frame having the usual sash, of a strip secured to a vertical face of the frame, a bar having its ends mounted in the space between said sash and strip, and a piece of flexible netting secured. to the outer face of said bar and having its edges in contact with said strip.

3. The combination with a window frame having the usual runway, and a sash in said runway, of a strip secured to a vertical portion of said frame and having its inside face at its upper end spaced from said runway, and at its lower end iiush with the edge of said runway, a flexible screen having its edge in substantial contact with said strip, and a bar to which said screen is secured, the end of said bar lying in said runway.

4. rlhe combination with a window frame having the usual sill, sash guides and sash, of a flexible screen, top and bottom bars to which said screen is secured, said bottom bar being in contact with the sill and said top bar being disposed between the two outside sash guides, and means carried by said guides for frictionally engaging the ends of said top bar for supporting the same.

5. The combination with a window frame having the usual outside trim including lintel and sash guides, of a plurality of spring clips secured thereto, each clip having a pair of downwardly extending arms, one of said arms being straight and provided at its end with a projection, said straight arm lying in the plane of the inner edge of the sash guide, a bar detachably held between `the arms of said clips with its inner face adjacent the sash and its lower edge resting against said projection, and a flexible screen secured to said bar.

.ln testimony whereof I have aiiixed my signature.
