WINDOW-SCREEN.

SPECIFIGATION forming part of'Letters Patent No. 768,416, dated August 23, 1904.-

Application filed December 15, 1903. Serial No. 185,323. 1110 model.) v

To all whom, it may concern:

Be it known that 1, CHARLES Gr. VVOODS, a citizen of the United States, residing at'St. Louis, State of Missouri, have invented certain new and useful Improvements in WindoW-Screens, of which the following'is a specification, containing afull, clear, and exact demounted upon the window-casing; a screenw1nd1n g roller mounted in said bearing-plates; 1

a cord-winding pulley fixed upon said roller; stationary binding-strips attached to the window-casing, the upper ends of said'strips being rounded to act as edge-guides and one of said strips being grooved to receive a spring and cord and there being retaining-notches at the lower ends of said strips; acord-guide roller at the upper end of said groove; a retractile spring attached at the lower end of said groove; a cord attached to said windingpulley, passing over the guide-roller and attached to said spring; ascreen-guide roller mounted in said bearing-plates; a windowscreen attached to and wound upon said wind ing-roller, passing over said screen-guide roller, passing over said edge-guides and down along said stationary binding-strips; a'movable binding-strip attached to the lower edge of said screen and adapted to engage in said retaining notches; handles attached to said movable binding-strip; clamping-levers attached to the window-casing, and edge-clamping strips carried by said clamping-levers to engage the edges of said screen and press them firmly against said stationary bindingstrips.

In the drawings, Figure-1 is avertical section of a window with my improved screen in position for use as seen looking in the direction of the arrow in'Fig. 2. Fig, 2 is an inside elevationas seen looking in the direction indicated bythe arrow in Fig; 1, parts being broken away to economize space. Fig.

3 is a perspective detail, upon an enlarged scale, at one ofthe upper corners of the window, parts being broken away. Fig. et is a perspective detail, upon an enlarged scale, of the lower part of thegrooved stationary binding-strip, the upper part being broken away. Fig. 5 is a cross-section, upon an enlarged scale, of the cord-winding pulley.

Referring to the drawings in detail, the

bearing-plates 6 are secured to the side pieces 7 of the Window-casing at the extreme upper ends and just inside of the parting-strips 8. The screen-winding roller 9 has its ends journaled in these bearing-plates, and the cordwinding pulley 10 has a square opening 11, through which the squared end of the roller is inserted. The stationary binding-strips 12 extend from top to bottom of the windowcasing, the upper ends 13 of said strips being rounded to form guides for the edges of the screen, and one of said strips has a groove 14, and both of said strips have retaining-notches 15 at their lower ends. The cord-guide roller 16. is mounted at the upper end of the groove 1 1 in line with the pulley 1O. The retractile coil-spring 17 is placed in the groove 14 and attached to the lowerend of the strip 12. The

cord 18 is attached to the winding-pulley 10,

wound upon said pulley and attached to the spring 17. The screen-guide roller 19 is journaled in the bearing-plates 6 close to the lower face of the upper casing-piece 20. The window-screen 21 is attached to the winding-roller 9, wound upon said roller, passing over the guide-roller "19 and passing over the screenedge guides 13,and passing down along the stationary binding-strip 12. The movable binding-strip 22 is attached to the lower edge of the screen 21 and is adapted to engage in the retaining-notches 15, and handles 23 are fastened to this movable strip. The clamping-levers 24 are pivoted to the plates 25, fastened to the inner faces of the casing-pieces 7. The edge-clamping strips 26 are carried by the inner ends of the levers 24, the outer ends of said levers serving as-operatinghan dles, and said strips being in position to press the edges of the screen againstthe stationary binding-strips.

In operation the handles 23 are manually engaged to pull the screen down, thereby unwinding the screen from the roller 9 and overcoming the tension of the spring 17 and winding the cord 18 upon the pulley 10. -Then the ends of the strip 22 are placed in the retaming-notches 15 and the levers 2 L are op- .erated to press the clamping-strips 26 against .the edges of the screen and in turn press the edges against the binding-strips 12. It is obvious that when the screen has been closed no flies or insects can pass through the window. Theguide-roller 19 holds the screen against the lower face of the casing-piece 20, the strip 22 engages the upper face of the lower casingpiece 27 and the screen pressing against the strips 12, thus leaving no place for insects to pass through.

I claim 1. In a window screen, bearing plates mounted upon the window-casing; a screenwinding roller mounted in said bearing-plates; a cord-winding pulley fixed upon said roller; stationary binding-strips attached to the window-casing, the upper ends of said strips being rounded to act as edge-guides, and one of said strips being grooved to receive a spring and cord, and there being retaining-notches at the lower ends of said strips; a cord-guide roller at the upper end of saidgroove; a re traetile spring attached at the lower end of said groove; a cord attached to said windingpulley, wound upon the pulley, passing over the guide-roller and attached to said spring; a screen-guide roller mounted in said bearingplates; a window screen attached to and wound upon said Winding-roller, passing over said screen-guide roller, passing over said edge-guides, and down along said stationary binding-strips; a movable binding-strip attached to the lower edge of said screen and adapted to engage in said i'etaining-nott'hes; handles attached to said movable bindingstrips; clamping-levers attached to the windew-casing; and edge-clamping strips carried by said clamping-levers to engage the edges of said screen and press them firmly against said stationary binding-strips, substantially as specified.

2. In a window-screen, a screen-winding roller suitably mounted; stationary bindingstrips attached to the window-casing, the upper ends of said strips being rounded to act as edge-guides for the screen and there being retaining-notches at the lower ends ofsaid strips; a screen-guide roller mounted in position near the limits of the window-casing opening, a window-screen attached to and wound upon the said windingroller, passing over said screen-guide roller, passing over said edge-guides and down along said stationary binding-strips, a movable binding-strip attached to the lower edge of said screen and adapted to engage in said retaining-notches; clamping-levers attached to the window-casing in apposition to the stationary bindingstrips and edge-elam 'iing strips carried by said clamping-levers to engage the edges of said screen and press them firmly against said stationary binding strips, substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
