.i Application tiled August VV'7, 1907. Serial No.l 387,518.

citizen ofthe 'United States, residing at city of 1Washiifigtori, District of Columbia, have invented certain new and usefull lm rovel ments in Window-Screens, oi which t ie following is a specification.

This invention coinprehends new and usef-ul improvements in that durable and efi'icient ty )e of ell-metal screens for windows and the ike, in. which the agent or .element over which the screen-cloth is stretched, remains es a ierxnanent part of the screenframe, the c oth beinginaintained taut by metallic binding'or clip members, which embrace the said stretching element and tightly clench andhold in criin ed condition, those portions el' the screen-c oth that are lapped over such element.

The present inx'fention has for its primary object'certain improvements in screens ofthe character before mentioned, whereby to produce a structure possessin to a high degrec the cliariicteristics of rigidity as against bending, torsional., or other stresses lunder severe use, without sacriliciug lightness rto gain strength. And a vfurther object ci the invention is an improved construction and arrangement of the stretch ing and holdingl element for the screen-cloth, said element being rust-proof and holding the screen-cloth stretched in such a manner that all possibility of bellying is precluded.

Yiiith these and other objects in View, es will more fully appear as the description proceeds, the invention consists-in certain constrnctions, ni'riingeincnts' ond combinations oi the parts that .l shall hcrcinzi'lfterfully vdescribe and then point out the novel ien- 'tuiacs and arrangements thci'eoiI iiithe appended chiiins.

. For i lull uinlcrstanding of the invention 'and the merits thereof and also to ncquirea' knowledge of the details ol construction and the incnns for ell'ecting` thc'result, reference is to be had to the followingr description :ind accompanynig drawings, iii/which;

Figure l is en elevation, with parts broken sway and other parts in section, 'ol' ii portion ol a window screen embodying the iinljn'ovements oi my invention; Fig. 2 is a transverse lsectional view, the section being taken approxiinntcly on the line 2-2'ol' Fig. 1 and, "ig 3 .is n detinl sectional perspective view ol' one corner of the screen. f

urability and Corresponding' and like parts are referred.

to in the followin description and indicated in all the views o the drawings by the same reference characters.

The stretching or lioldingeleinent 1 for the screen cloth isconstructcd, according to the principles of iny invent-ion, and in the manu- `facture of the screens, by bending or doubling upon itself in a longitudinal direction, ametallic strip 'or sheet of ,the requisite or desired length and width, the edges ol the two inembers ,2 of the s trip being bent outwardly in opposite directions, to form the outstanding flanges 3, as best seen in Fig. 2. The doubled strip-is lthen cut at the points where the ,corners of the screen-frame are to be formed,

slits 4 beingreduced, as best seen in Fig. 3, so as to pro uce a mitered joint at the cor ners, the metal being suiliciently pliable and yet tenacious to permit of the angular bending to form a corner, While the lianges -3 remain integral land continuously connected together. The ends of the doubled strip, after it has been bent to form the ropcr rectimgular structure, may obviously ne brought together et any desired point, that is, the meeting ends of the strip may be located at any point in the top or bottom, or either of the two sides of the complete screen.

The screen-cloth 5 has its edges lapped over the stretching and holding element 1, as 1 best seen in Fig. 2, so as to produce e decided shoulder et the edges of both flanges 3. ln order to hold the screen stretched over the stretching and. holding element 1, I provide the metallic binding or clip members (i, of iron or. sheet metal, adapted to be bent to retain the form imparted to it, said binding or clip members being 1placed around the.

stretching and holding e ement l in such ii nimmer as to closely embrace the saine. and clcnch and hold the stretched screen-cloth. lit is to be particularly noted that the binding or clip members 6 are Jrovided with criin is or corrugatioiis 7 which securely clencli the overla` )ping portions of the screen-cloth and securely prevent the latter from bellying, even after continued end severe use, the said members (5 also preferably engaging or contacting. with.' the screen cloth at 'the outer edges ol the flanges 3, as clearly illustrated in liig. 2, so es to assist in this binding action,

Corner pieces 8 are then'placed over the meeting ends of the binding or clip members.

6 and riveted thereto, as indicatednt If desired, corner braces 10 of substantially L-shape, as bestnseen in Figs. 1 and 3 may be inserted between the compleinental members 2 of the element 1 at the corners so as to extend across the mitered joint 4,- the rivets 9 extending through the two ends of these corner braces and thereby assisting in strengthening the structure. i do not regard these corner pieces as essential to the success of my invention, but they possess manifest advantages, andl may be easily applied and used, if 'found desirable.

From the foregoing description in connection with the accompanying drawings,l it Will be seen that'l have provided a screen in which the screen-cloth is securely gripped by the binding or clip members 6, the overlapping portions of the screen-cloth lforming distinct angles or shoulders around the substantially T-shaped stretching and holding element, so that the completed structure will be capable of withstanding hard usage without breaking down or bending, and without permitting the screen-cloth to become loose.

It is to be understood that my invention is notlimited toany particular metal out of which to form the stretching and holding element 1`. Manifestly, the inherent construction of this element with its two lies or members 2 in contact with. each otiier and itsl laterally extending and outstanding ilanoes 3, results in a substantial structure, the langes resisting any bending or torsional strain which would otherwise be possible. Hence, zine may be employed for this element, as it is absolutely' rust-proof and as its natural pliability is overcome by the arrangement of parts just noted, oi', if desired, the element 1 may be composed of sheet iron or steel coated or galvanized to resist the action of the elements.

Having thus described the invention, what is claimed as new is:

1. A screen, com rising a screen cloth and -frame therefor, t e trame embodying a stretching and holding element over both sides of which the edges of the screen cloth are lapped, said element being provided along its outermost edge with longitudinally lextending and outstanding flanges, and binding or clip members embracing and inclosing said stretching element, and gripping the screen cloth against the edges oi" the ilanges. v
