Application filed November 11, 192 0.

To all whom it may concern: 1 r

Be it-known that I, JAMEs H. GRAYSON, a' citizen of the United States',{jresidingj at 'Kansas City, in the county of Jackson, State of Missouri, have invented new and useful Improvements in Window Screens, of which the following is a specification. 1

This invention is awind" w screen adapted to be positioned between the upper and lower sashes of'a window and so arranged as to be moved by one of the sashes into position to close the opening left by said sash when the latter is opened. 7

The invention will be readily understood from the following description of the 'ac-' companying drawings in which;

Figure 1 is a front elevation of a window having the improved screen applied thereto.

Fig. 2 is an enlarged vertical section partly broken away and taken on theline 2-2 of Fig. 1. Fig. 3 is an enlarged front elevation of a corner of the window partly broken away. In the drawings a usual window frame is shown at 1, having the usual upper and lower sash 2 and 3 slidable therein in well known manner. A space at isleft between the adjacent surfaces of the upper and lower sashes in which the improved window screen is mounted. For this purpose a guide way 5, preferably, formed of metal is provided in the space 4, said guide Way extending across the top of the window frame and down the sides thereof. A groove 6 is provided in this guide way in which the edges of the window screen are received to provide a guide way for the screen and a tight joint between the window frame and the screen. The screen is shown as formed of a usual mesh 7, the edges of which are re inforced to form the frame of the screen as by a metallic strip bent over the edges of the mesh and abutting against the opposite surface of the mesh as shown at 8 and 9.

The screen is normally held in its guide way at the upper end of the window frame and is preferably of such length as to end at the top of the lower sash when it is in this position, as clearly shown in Fig. 1. When the lower sash of the window is raised the screen is adapted to be lowered so as to close the opening left by the lower sash. For this purpose flexible connections running over pulleys at the upper end of the window frame are connectedat their respective ends to the screen and to the lower Serial in. 423,280};

sash, so arranged that when the lower-sash is closed the screen will be supported by saidflexible connections at-the'npper end of the window frame and'when the'lower sash isfraised'the screen will be moved by gravity downwardly in its guide way to close 7 the opening left bythe lower sash The flexible connections' are shown as tapes '10 ,having hooked ends'llgreceived in -the frame plate 9 of-thescreen.- These-tapes pass over pulleys shown as comprising rol lers 12 journaled upon pins l8-having offset ends 14 adapted to be received within the guide way 5 for supporting said pins. The I gnide way is, preferably, a hollow construe tio'n, and is cut away as shown at 15'above said pins to permit of the ready insertion of the'ends of said pins within the hollow guide way. The opposite ends of the tapes 10 are 'removably connected to the lower' sash of the window as'by providing hooks 16 upon the-top. of the flower sash,'these hooks being arranged to receive at the ends of the tapes 10..

'.When it is desired, to lower the screen 1 without raising the lower sash of the window it is only necessary to unhook the tapes from the lower sash and the screen 'will' then drop to a position in the lower portion of the window frame. Usually, however, the tapes 10 will be connected tothe lowersash so that the movement of the screen will be' controlled by the movement of the. lower sash as previously described. 7

It will be obvious that various changes may be made in the construction'as' thus described withoutdeparting from the spirit of r the invention.

What is claimed is:

V 1. A window' screen comprising an inverted U-shapcd frame that is adapted to be positioned in a window frame between the sashes therein, said inverted U-shaped frame being formed of tubular material on the inner face of which isformed a continuo'uschanneha screen carrying frame.

arranged for sliding movement in said chan- I nel. flexible'members secured to the upper:

rail of said screen carrying frame, and flexible member su-pportingrollers journaled on the upper portion of the tubular frame.

2. A window screen comprising anin verted .U-shaped frame formed of sheet metaland adapted to be positioned in a window frame between the sash thereimthe legs of-said Ueshaped" frame being of a length equaling the height of the window opening whereby'to serve as parting strips between the sash, the inner faces of the vertical and horizontal portions of said inverted U-shaped frame having channels formed therein, and a screen carrying frame ar ranged for sliding movement in said channels.

3. A window screen comprising an inverted U-shaped frame formed of sheet metal and adapted to be positioned in a window frame between the sash therein, the

inner faces of the'vertical and horizontal nected to the second frame, said flexible means being adapted for connection with the lower sash of a window whereby the screen carrying frame will be lowered or elevated according as thesash is raised or lowered. i p

In testimony whereof I have signed my name to this specification.
