Referring in detail to the invention:

In the screen section Figure 1 the screen I is fashioned of flexible screening material into which at spaced intervals relatively rigid horizontal rods, stout threads or wires 2 are interwoven. At the extremities of these rods small beads 3 of firm material are afiixed. When the screen edge 4 is fitted into the path 5 of the runway 6 these beads become positioned in the recess I and are held in place by the edges 8 of the inwardly folded portions of runway 6 (see Figure 7). It is preferable, though not essential that these beads be of the rotatable type to permit greater ease of movement androllability of the screen assembly as it is raised and lowered. Referring further to Figure 1, the screen I is fitted at its top end with a fairly rigid shaft 9 that is narrowed at its extremities and widened throughout its middle portion. This shaft is narrow at its ends to permit 2012iim's.

The purpesebr this slot is for the passage of screen I from the roller contained within the housing assembly. The housing assembly is provided with openings 22 for fastening the cover to the box I8 and securing both to the base of a Window sill. In the fully assembled invention this housing together with a screen and roller attached may be built into the base of the window frame as shown in Figure 7 in newly constructed Window frames, or, as is preferable it may be simply fastened to the base of the ordinary window sill.

In describing Figures 4, 5 and 6 reference is directed to the drawings for the general shape of these parts. Figure 4 is a jacket 23 made of rigid material adapted to fit in the slideway wherein the Window sash rides. Figure 5 is a runway 6-er guide of rigid material and is fashioned so as to fit within jacket 23. The runway 6 is shaped as illustrated in the drawing Figure 5 and is so constructed as to receive th screen edge 4 and the "that the sash is raised.

narrow ends of shaft 9, while the runway recess 1 is made to receive beads 3 of screen section I. Figure 6 is simply a stop or lid in the form of a right angle having a vertical side 24 which is made to fit in the slideway of the window frame, and a base 25 which is shaped to conform to the contour of the jacket Figure 4 and the runway Figure 5. This Figure 6 serves as a lid or stop to prevent the runway 6 from slipping upward out of the jacket 23 due to friction or rubbing arising with the raising of the window sash.

The use and assembly of this invention is relatively simple. In explaining this it is desirable that reference be made to all the drawings and principally to the composite drawing Figure 7.

In putting it together the lower end of thescreen section is passed through slot it of the housing cover II and is attached and rolled about the spring roller Hi. The spring roller is then placed in position in box l8 with cover H on the top of the box.. The housing assembly is then secured lltolithe base of the Window sill. Jacket 23 1521-- fixed to the slideway of the window frame-runways is inserted down into the jacket and lid Figure- 6 is secured in place over the jacket and runway in the slideway of the window frame. The screen is then raised with the shaft ends and screen edge in the path 5, of the runway 6, and

'yvith its heads 8 in therecess of the runway. Tabs 13 are secured within a groove made in the base .of the window sash. The apparatus is now ready for operation.

7 Simply raising the sash to which thescreen is "attached will screen the window to the extent Itis to benoted at this point that the window sash has a vertical groove 26 to permit thesash .toclose down, over and about the runway assembly. This groove is only wide enough to fit about the runway assembly with as little play as possible and is long enough to receive the runway assembly as it rises into the groove upon the closing 'of the window sash. It is this groovethat permits the runway assembly to serve as weather stripping at the sides whenthe window is in a closed position.

This vertical groove is not, however', essential to the use of this invention as it may be used with- .out such a groove by aifixing the apparatus to that portion of the sill beneath the upper window and by attaching the top of the screen section to the sash of the upper window. When used in this manner the portion of the window opening opposite the lower window has a fixed screen.

"T It is also to be noted that the purpose of the groove at the bottom of the sash as shown in Figure 7 is to hold the tabs and shaft of the screen section with the end that when the window sash is in a closed position the shaft within the groove will serve as weather stripping. However, it is not essential to the operation of this invention that the screen section attach to the bottom of the sash in the manner described, as other methods obvious to those skilled in the art may be used to attach the screen section to the windowsash and accomplish all or some of the objects of this invention.

Variations in this invention obvious to those skilled in the art may be made in actual practice without departing from the essentials of this inventionas claimed.

Iclaim: Y

1."In a roll screen structure of the character described a runway guide for the rotatable beads and side edge of a rollgscreen comprising in combination, a runway, ajacketabout. and holding suchrunway slidable. therein, and a lidcovering at the extremities thereof, incombination with a guide runway assembly having a jacket holder and madeupor an integralv piece ofmaterial to forming adjacent right angles, the free. ends of each right angle rising inthe center and then foldinginwardly, forming a recess, said beads being workable in said recess and a stop lid atop such runway andjacket, all substantially as shown and described.
