Window or door screen.

Application filed June 27,1904. Serial No. 214,407.

To all whom it may concern:

Be it known that I, William B. Lee, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of 5 Missouri, have invented anew and useful Window or Door Screen, of which the following is a specification.

My invention relates to screens for doors or windows, and has for its objects to produce a io comparatively simple inexpensive device of this character which in practice will normally remain in closed position for effectually closing the window or doorway and one which may be readily moved to open position and will 15 when released return automatically to its normal position.

To these ends the invention comprises the novel features of construction and combination of parts more fully hereinafter described. 20 In the accompanying drawings, Figure 1 is an elevation illustrating the device applied to a window. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1, showing the screen in normal closed position. Fig. 3 is a view simi25 lar to Fig. 2, showing the screen open.

Referring to the drawings, 1 designates a window, 2 its frame or casing, and 3 my im. proved screen applied for normally closing the lower portion of the casing, these parts, 30 with the exception of the screen, being of the usual or any preferred construction and material.

The screen 3, constituting the subject of the invention, comprises a sheet of wire-netting 35 or other appropriate reticulated flexible material cut to the suitable size and having its longitudinal side edges attached in any preferred manner to the side bars or stiles 4 of the screen - frame, the stiles being in turn con40 nected at their ends by means of end rails or members 5, preferably consisting of suitable lengths of comparatively thin spring metal constituting leaf-springs, the ends of which are riveted or otherwise secured to the ends of 45 the stiles.

One of the stiles 4 has attached thereto at its ends angle-clips 6, perforated for the reception of screws or other fastening devices 7, by means of which the screen is permanently secured in position within and to the window- 50 casing, while the other stile has attached thereto a finger-piece 8, adapted to be grasped for opening the screen.

In practice the screen, which is normally flat, remains in closed position, as illustrated 55 in Fig. 2, being ^maintained in said position through the action of the leaf-springs 5, which, however, will readily yield to permit opening of the screen, as shown in Fig. 3, attention being directed to the fact that upon re- 60 lease of the screen the springs will serve to automatically return the same to closed position.

From the foregoing it is apparent that I produce a comparatively simple inexpensive de- 65 vice which in practice will efficiently perform its functions to the attainment of the ends in view, it being understood that minor changes in the details herein set forth may be resorted to without departing from the spirit of the in- 7° vention. For example, while the device is illustrated and described herein as a windowscreen it obviously can by mere changes in the proportions of the parts be adapted for use as a screen-door, which I consider within the 75 scope of the invention.
