J., assignor of one half to August Bruns, Port Chester, N. Y. Application September 14, 1944, Serial No. 554,014 2 Claims. (01. 160-273) This invention relates to window screens such as are adaptable for use in association with the windows of the ordinary double ‘sash type, the invention having reference, more in particular, 'to a flexible rollable type screen, that is, one which wound on a spring-actuated drum or roller, whereby to permit it to be raised and lowered similarly to window and porch shades. 'In carrying out my inventive idea, I have had tated 90° counterclockwise, this taken on the plane of the line 3—3 of Figure ,1, . Figure 4 is a fragmentary 'elevational view de tailing ‘the clip-equipped longitudinal ‘edge por tion of the screen. Figure 5 is ‘a fragmentary horizontal ‘sectional view similar to Figure 3. Figure 6 is a ‘fragmentary detail view to bring out the construction of the rigid and ‘flexible in mind the adoption and use of a structure which 10 screen wires. lendsitse‘lf admirably well for use on conventional Before referring in detail to the various views ‘window frames, the arrangement and designing of parts being such that the installation may be made either ‘facing the exterior or outside of the dwelling, or facing the interior rooms. More speci?cally, novelty is predicated upon the adoption and. use of simple and expedient pairs of vertical angle irons, these being provided with opposed and spaced ?anges to thus provide track like guides, the longitudinal edges of the rollable ?exible screen wire projecting between said guides and having spring contact clips functioning as shoes to guide and tautly maintain the screen as it is rolled up or down, as the case may be. More explicitly stated, the present invention has to do with a screen which is adapted for use in a frame and on a roller with special stabilizing ‘of the drawings, it may be pointed out that the invention, briefly comprehended,‘ is- character ized by pairs of coacting ?anged angle irons, these mounted on anchoring plates on the window frame structure. The longitudinal edges of the raisable and lowerable ?exible screen project into the guide tracks and-carry spring clips which slide up and down in contact with the angle irons. At the top of the structure is a casing or- housing having a spring wound roller and the screen is wound thereon. Referring now to the drawings by distinguishing reference numerals, it will be observed that the structure is supported or mounted on the exterior of the window frame, the latter denoted gener ally by the numeral Il. As seen for example in Figure 3, the attaching devices are in the form of right angle plates l2 screwed or otherwise an devices attached to opposite edge portions of the screen, these devices being arranged in longi~ tudinally spaced relationship and each device 30 chored in place. The inwardly projecting ?anges actually made up of a pair of spring clips. The of the plates [2 carry the aforementioned screen spring clips have their inner adjacent ends later , guide and retention tracks. Each track or track ally bent and fastened to opposite faces or por tions of the edges of the screen fabric, the adja way is made up of duplicate angle irons l3 and M, these being provided with laterally directed ' cent portions of the clips, that, is the portions 35 and spaced parallel ?anges I5. As detailed in adjacent the screen being laterally bent and enlarged form in Figure 5, it will be observed bowed to provide resilient guides and the free that the inner edges or faces of these ?anges 15 end portions of the clips constituting resilient re are provided with shallow grooves or runways IE tention shoes for coacting with parts of the frame to accommodate the curvate bends or shoe por work. tions I‘! of the spring trackings and guide clips It. The adjacent longitudinal edges of the screen Other features and advantages will become l9 project into the guide tracks and the laterally more readily apparent from the following descrip directed inner portions of the clips 18 are riveted tion and the accompanying illustrative drawings. In the drawings, wherein like numerals are em: 45 or otherwise secured to the projecting screen edges, as indicated at 20 (see Fig, 5). As before ployed to designate like parts throughout the stated, this idea of the special angle irons form views; ing the guide tracks, and the spring clips I18 mov Figure 1 is an elevational view, that is, a view ing in said guide tracks and constituting slides observing the complete structure, the screen being and screen tautening shoes is an important phase partly elevated and the structure being seen as of the invention. it appears from the outside of the building. I next call attention to the upper or overhead Figure 2 is a fragmentary sectional and eleva structure, this embodying a longitudinally elon tional view of a screen winding and unwinding gated horizontally disposed box-like housing or spring-equipped roller. Figure 3 is an enlarged horizontal section ro casing of appropriate construction, the same in 55 dicated as 22 and containing a spring roller 28 2,407,784 3 and the screen being wound on said roller. Then, and as shown in Figure 2 of the drawings, the roller 26 is of a simple spring wound cylinder type and is provided with journals which are suitably mounted in adapter sockets 21 formed in the aforementioned casing structure. I now call attention to the lower slidable end structure of the screen. This is characterized by screen and window can be built in as an original installation. A careful consideration of the foregoing de scription in conjunction with the invention as il- . lustrated in the drawings will enable the reader to obtain a clear understanding and impression of the alleged features of merit and novelty suf ?cient to clarify the construction’ of the invention as hereinafter claimed; ‘f I ‘ > _ 4 a rigid wooden'or' equivalent horizontal ‘bar 28 Minor changes in shape, size, materials and re which forms a sort of false sill and this has its 10 arrangement of parts may be resorted to in actual opposite end portion bifurcated with the furca practice so long as no departure'is made from tions 29 straddling the track-forming angle irons ' the invention as claimed. ‘I 3 and I4. The furcations are provided with suit ably mounted anti-friction rollers 30 to, facilitate raising and lowering of the screen in proper per pendicullar order. ' As before stated, and as diagrammatically in- ‘ dicated in Figure 6, the screen itself is made up of relatively rigid parallel rods or stout wires 43' connected together by highly ?exible intersect ing vertical wires 44. This forms a sort of lattice like structure having the‘functions of an ordinary ‘wooden slat porch shade or screen. That is to say, the structure is easily roll-able and yet sui?cient Ely rigid to perform the desired results. The structure herein shown and described has the advantage of operating like a window shade, whereby to permit the housewife to attend to cleaning duties and washing of windows with I claim: . 1. In a structure of the class described, a guide; way for a screen of the class described made up of opposed parallel angle irons having flanges, the inner faces of said ?anges being used to provide runways, a screen edge projecting between the flanges adjacent said runways, and. spring clips attached to said screen edge and having rounded portions workable in said runways. " . 2. As a component part of an assemblage of the class described and as a new article of manufac ture, a screen adapted for use on a rollable screen assembly of the class described comprising a screen proper, and stabilizing devices attached to opposite vertical edge portions of the screen, said devices being arranged in ‘longitudinally spaced relationship, each device ' comprising a pair of expediency. In the fall when screens are no 30 spring clips, said clips having their inner adjacent longer needed, it ‘is rolled up and left in that po ends laterally bent and fastened to opposite sur sition until spring. The screen and its frame faces of the edge portion of the screen, the por structure will preferably be made of rust-free metal for sake of longevity. The screen can be tions of the clips adjacent said laterally bent ends being bowed to provide resilient guides, and the easily attached by~a few wood screws without any . 35 alteration to any type of window, ‘and it can be placed on either the outside or inside of the win dows of old houses. For new construction, the free end portions of the clips constituting resil ient retention shoes. - OLE J. HOFFSTAD.
