WINDOW SCREEN REENFORCEMENT Filed Sept. 9, 1931 2 Sheets-Sheet 2 Patented Dec. 27, 1932 UNITED STATES PATENT OFFICE ALVIN F. NYE, OF ROCHESTER, NEW YORK, ASSIGNOR OF ONE-HALF TO WILLIAM 'j KEYEL, 0F PENFIELD, NEW' YORK WINDOXV SCREEN REENFORCEMENT Application filed September 9, 1931. Serial No. 561,882.

My present invention relates to movable screens and mountings therefor, such as the roller screens that are applied to windows and porches and embodying a sliding screen body guided in its lateral vertical edges and raised and lowered in the manner of a window by means of a cross rail at the bottom cooperating with the window sill when the screen is closed, and the invention has for its ob ect to reenforce and improve the attachment of the screen to this rail by way of giving additional support to the lateral edges of the screen that travel in channels or guides in the sides of the window casing or frame.

T 0 these and other ends, the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Fig. 1 is an inside elevation of the lower right hand corner of a window casing and sliding screen constructed in accordance with and illustrating one embodiment of my invention, the screen being shown partially raised;

Fig. 2 is a similar view showing the screen lowered against the sill;

Fig. 3 is a horizontal cross section through the screen guide;

Fig. 1 is an enlarged fragmentary elevation of the lower right hand corner of the screen and rail alone, showing the details of the reenforcing element;

Fig. 5 is an elevation of the opposite side of the reenforcing element alone;

Fig. 6 is an enlarged vertical section taken on the line 66 of Fig. 4, and

Fig. 7 is an enlarged vertical section taken on the line 77 of Fig. 4.

Similar reference numerals throughout the several views indicate the same parts.

My improvements are applicable to a screen mounting, such as that fully shown and described in my copending application, Serial No. 180,122, filed April 1, 1927, and in the present embodiment, I have illustrated them in connection with that disclosure, showing only so much of the general structure as is necessary for an understanding of the construction and mode of operation of my improvement. As to these previous major elements, briefly described, 1 indicates the screen body having its lower edge secured to a bottom rail 2 guided by bolts 3, shown in dottedlines, p'rojectinglaterally intoside channels 4 secured by flanges 5 to the window casing 6. The bolt is slidably operated by means not shown to move longitudinally'of itself inwardly and outwardly of the channels 4 and lock and unlock with shoulders formed by depressions 7 in the bottoms of the channels to support or lock the screen at different elevations.

After the screen has been adjusted up and down, as desired, the expanse thereof is drawn taut laterally by catching its selvage edges 8 between clamping jaws 9 within the guide channels 4, as shown in Fig. This effect is accomplished through operating levers 10 which, when moved upwardly to the vertical position of Fig. 1, release the jaws 9 allowing the screen to be moved and which, when moved to theposition of Fig. 2, not only clamp together against the selvage edge of the screen, but, when so clamped, move inwardly within the channels 4.- exerting a lateral p'ull'on the screen at both sides. The specific action hereis not necessary to an understanding of the present-invention;-

The' lower edge of the screen body is: secured to the rail 2 in the manner 'bestsh-own in Figs. 6 and 7 The rail is preferably hollow having the rectangular tubular form shown. The upper edge ofits front wall is offset rearwardly at 11 against its rearwall, which latter is doubled over or crimped down, as shown at 12, and the lower end'of the screen is doubled over itin turn with its raw-edge inside, so that the screen body generally extendsin'a plane a boudzcentral-ly= of the rail, so that there is equilibrium and there is notendency for the latter tocook in its guide. My reenforcingmember consists of a doubled metal strip of yoke-like form embracing or clipped over the bottom of the screen body'and' indicated generally at13, the loop at thispoint extendinglaterallyy'beyond 'theselvage edge '8 and into the channel 4. One arm or portion M thereof is clamped by stamping or pressing with the raw edge of the screen between the elements 11 and 12 of the rail, while the other arm 15 extends across the screen where it emerges from the rail, and all of these parts are held securely together by a rivet 16. H I

The selvage edge 8 for a distance back is preferably reenforced by extra longitudinal wovenscreen wires17,anda vertical up- H wardly extendlng plate 18 proceeding from" about the center of the member 13 is securely afiixed to such reenforced margin'by means of spurs 19 struck out therefrom and bent down over the transverse wire strands. Similar spurs 20 forming serrations at the bottom edge of the plate 15 are clamped through the lower loop of the screen body and around the lower end of extension 18. The latter is additionally secured to the reenforcing body 13 by a prick punch 21 into it through the portion 14 from the rear.

This corner reenforcementl have described is simple and addslittl'e to the cost of manufacture, yetisstrong a-ndigives general rigidity to the lower corners of the screen body which would otherwise have a tendency to become distorted interfering with thefree running of the screen within their guiding channels and between the gripping jaws. The screen must project into the latter, yet the rail 2 can not do so, terminating at the mouth of the channel. The extension plate 18 is so thin that it does not interfere with the gripping of the j aws 9 and can be gripped along with the screen 1 I claim as my invention:
