F. M. KENNEDY ROLLER SCREEN Filed Aug. 20. 1951 A TTORNEYnS Patented Jan..12, 1932 FRANCIS M. KENNEDY, OF KANSAS CETY, MISSUR ROLLER SCR-EEN Application filed August 20, 1931.

rl"his invention relates to Window screens commonly known as the roller or disappearing type and has for a primary object the provision of such structure wherein is em- 5 bodied a new combination of parts, the elecompleted and it is desired to equip the same with screens of this character.

One of the objects of the instant invention is the contemplation of novel struct-ure in a roller screen adapted to impart lateral or transverse tensioning to the netting after it has been moved to an operative position.

A still further object of the invention is to provide means at the bottom and two sides of the netting of a roller screen that simultaneously imparts a stretching force to said netting, whereby bulges or undulations are eliminated.

Minor objects of the invention will appear during the cour-se of the detailed specifica* tions, having specific reference to the accompanying drawings, wherein:

Figure l is a view of a window frame equipped with a roller screen embodying this invention.

Fig. 2 is an enlarged, fragmentary, vertical section along line lil-II of Fig. 1.

Fig. 8 is a fragmentary, detailed view through the bottom portion of the screen, taken on line III-III of Fig. 2.

Fig. el is a vertical cross section through the same part of the screen, taken on line IV-IV of Fig. 3.

5 is an enlarged, fragmentary, detailed view through the .side guide, taken on line V-V of Fig. l, and

Fig. 6 is a fragmentary view througha portion of the side guide taken along line VI-VI of Fig. 5.

rlhe application of this screen is accomplished through extremely simple structure. The screen may be positioned to operate over any opening, but is particularly useful in protecting windows which are formed of a frame 8, part of which includes strip 10, against which one of the vertically sliding sashes Serial No. 558,206.

bears. lflhile the head portion of frame 8 may house a spring roller l2, in the instance shown, a cowl 14 is utilized which becomes eliective particularly when applying this structure to old buildings. Roller l2 is of the ordinary spring-actuated type to which one end of netting 1G is secured in any suitable manner to allow roller 12 to wind netting 16 when the latter described latch, positioned at the bot-tom of netting 16, is released.

The sill 18 of frame 8 is approached after netting 16 is unwound from roller 12 and when the completely closed position is attallied, a scaling felt 2O functions to compensate for irregularities and to provide positive 6 closing. Felt 20 and netting 1G are secured between two plates 22 and 2a, each of which have registering handle openings 26 formed therein for use in operating the screen.

An effective latch co-opcrates with remaining structure of this screen in holding netting 16 in taut condition. To fulfill one of the objects of the invention, it is contemplated that this latch be releasable from either of the handles 26. Sill 18 supports lug- 28 and a pair of ears 30 pivotally support latch 32 intermediate its ends which project oppositely as illustrated in Fig. a for the purpose of engaging lug 28 and bar 84. Reference to Fig. 3 teaches that bar 34 is reciprocably mounted between plates 22 and 211, the latter forming a clearance opening 36 to allow free movement of bar 34: and latch 32.

Inclined faces 38 move against and actuat-e latch 32 when bar 84 is moved in either direction by pressure upon bottons 40 provided at each end of bar 34 and disposed within handle openings 26. A compression spring 42 maintains bar 34 in a. set or inoperativeposition and serves to retrieve the same after movement to operate latch 32. ln operation, inclined faces 38 move latch 32 outwardly at its upper end away from plate 2a, which si multaneously moves the lower end of latch 32 inwardly toward the same and out from beneath lug 28. Then latch 32 is not in 1nolding posit-ion, spring tension in roller 12 draws netting 16 to a wound position about this roller.L

Novel guides along each of the vertical sides CTI Each side guide-comprises an inner;and.an

outer plate 46 and 48 respectively, secured to t ame 8 by screws or analagous means-150i. These plates coact to form the guide and eX- tongue-'52 is formed by each plate 46 and 48 respectively, between which is positioned yoke 54or lateralmovein'ent.
