Toall team it may concern:

Be it known that we, EitNEsT 'S'i'A-RBUCK and YViLLIAM A. SEELYE, citizens of the United States, residing at Peoria; in the county of Peoria and State of Illinois 'hav'e invented certain new and useful Improve ments in Window-Screens; and." we. do herebydeclare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art tOWlllh-it appertain's to make and use the same.

This invention pertains to improvements in window screens; It relates particularly to the manner of constructing the frame of a screen and to the inode of holdingand stretching the wire fabric.

An object of the invention is to constrhct a metal frame screen that will be practically indestructible, thoroughly strong and rigid in use, that can be readily assembled i or disassembled by an inexperienced persoh,

and that will be low in cost.

Another object is to construct a window screen in which the several parts of it's frame, which may be termed its rails, are separable from one another and forth other parts which hold the fabric so that the screen can be rewired, inaking use of certain corner braces for securing the several parts together.

Another object is to provide, in a window screen, 'a series of frame portions or rails each made up of two separable portions one inclosed by the other and inverted with respect' to one another and so arranged that the inner one becomes the holdingporti'on for the wire fabric while the other 'the enter one, becomes the holding member for'both the said inner portions with the fabric, the two in conjunction being adapted to draw or stretch the fabric tight in the act'of assembling; Still another object is to 'construct'each frame portion or rail of "a screen of two parts which after adjustment relatively to sires-:11 the wire fabric can be "secured in a desired adjustment by a corner brace by which to hold the 'fabrid permanently stretched. a a J I Besides thf'e'se' bje'cts "the invention. relates sibf mastrutiw andare ranginent of parts to be'fptointed outin cdmpanying drawings, in which;

Screens made up of wooden frames are very diflicult to properly rewire, are destructible, and the process of rewiring is very tedious and not easily accomplished by one not skilled in such work. It is our purpose to provide a form of metal frame for a screen that will be practically indestructible and of a form such as will admit the most inexperienced person to rewire the screen in a short time with a minimum of effort, and above all the fabric of the completed screen will have been stretched perfectly tight, because of certain necessary acts to accomplish the reassembling of the parts.

\Ve are aware that it is not new to construct screens of metal since we have knowledge of a number of patented devices. But in bringing out the form of screen now to be described simplicity is the first requirement so that the parts may be readily and easily assembled and disassembled, also that it shall be low in cost because of its simple construction and that any person entirely inexperienced in handling tools or of performing any sort of mechanical work can do all work necessary in rewiring the screen or taking general care of it. In order that the construction of the screen and its manner of handling can be most easily and clearly understood, the drawings have been prepared with a view to illustrating the several steps in putting the screen together.

In the figures A represents a piece of screen wire, or wire fabric of the proper size of a given screen to be assembled, it being observed that each corner of the fabric is recessed as shown at A. Each of the edges of the fabric is now inclosed in a channel member of metal B plainly shown in plan in Figs. 8 and 4. The width of each member B is substantially equal to one half of the width of that portion of the screen projecting outward from the recess. Upon being placed as described each member is turned over upon the fabric as shown'in Fig. 4:, thus bending the wire along the edge of the members as shown clearly in Fig. 6. Fig. 2 shows three of these members thus placed and turned over uponthe fabric leaving the fourth edge free. Fig. 5 shows the four edges complete in this'respect.

It is observed that the length of each member B is substantially equal to the length of the edge of the fabric between the recessses. By recessing the corners, as explained, after the members 13 are turned in, there are no parts of the fabric exposed or that will prevent the easy handling or manipulation of the parts described.

C represents a channel member placed over each of the members B and the fabric adjacent thereto, this being entirely disclosed in Figs. 6, 7, 9, 11 and 12. The recesses or channels of these members 0 are such as to receive each member B and the wire fabric in a snug fit as clearly shown in said Figs. 11 and 12. The ends of said members are mitered and the shortest measurement of said members, or that between the innermost corners thereof, is substantially equal to the length of the members B.

D represents a corner brace or fitting of sheet metal. It is designed to receive and inclose the ends of the members C at each corner of the screen and for this purpose when placed in position are slightly spread so as to be sprung over said members when the parts are assembled with the fabric. In Fig. 9 the assembled relation of the parts is shown by dotted lines X indicating the abutting mitered edges of the members C. The latter when assembled withinthe said corner brace D represent the full outer measurement of the screen to fit'between tracks or guides indicated at E, Figs, 9, '10 and 14.

The wire fabric when prepared for use is cut to a certain size and when the members B are placed thereon and turned over upon it as already described, the distance between the inner edges of two opposite ones must be preferably slightly less than the distance between the inner edges of the opposite members C corresponding in position thereto. This relation provides for tightly stretching the fabric in the completed screen. The dotted lines in Fig. 9 indicated by B represent the members B as the position they occupy before the fabric which they hold is stretched. The last act in the assembling operation is now to stretch the fabric. This is done by employing a clamp for ease and convenience, one part of which lies upon the outer surface of the member C and the other upon the inner edge of the member B. Now, by drawing up the clamp. B is forced inward into C to substantially the position shown in full lines in said Fig. 9 whereupon a screw F is inserted through holes G in the brace D, Fig. 14, one of which may be threaded to receive the threaded portion of the screw which, when tightened, firmly clamps said brace upon the part inclosed by it. The screw may serve to prevent the movement of the members B outward, although the fricton set up by clamping the brace will be suflicient. That is to sav,'the screw since it lies in the angle of the frame can lie suiiiciently close to the members B so they can each bear upon it and, of'course, said screw will pass through the fabric the latter beingspread-totormaholexvnsshown .invFig. 7 by meansofwawl=or similar "implementto make \room forthe introduction of thescrew.

The stretching action will preferably take place simultaneously at, all four edges so 1' that the braces D can all be tightened iat once. The brace is paneled at F so that in moving the sides toward one another the edges that underhangthe. members C, as shown in Fig-12, will result in firmly in- .closing those parts. However, outward from the screw. the metal is not indented but lies in the same plane with the outermost surface of the. side of the brace to receivea certain guiding portion J aboutto be described.

, During the act of stretching the the abutting .mitered ends of the members C held within-the braces D are the parts upon which the strain is placed in the clamping operation and these also maintain the fabric in its permanently stretched cond-ition.

.Fig. .14 shows a form of double track to receive the upper and lower. screens in separate guideways but-where a-single track is employed, which is preferable from the fact that the screens can be removed without dis- ,cated so as to provide an upper and alower extension or tongue, one of which is bent beyond the plane of the other as clearly shown in Fig. 13, whereby, as shown in Fig. 10, one of the saidtongues lies at each side ofthe said guiding portionH of the track.

The corner brace .D is provided with integral projections M as shown in Fig. 15, which are formed by forcing the metal outwardQ, "One: of these projections .liesat each side 'of-the said guiding portion J and holds the same in its proper position .in use. The said members J are duplicates, one being inverted to take its place upon the upper screen.

'momentortwo.

device may be employed to hold" the upper screeninjits -properposition and to hold the lower one in any raised position "andi n fact if constructed of spring-metal the guides J themselves mayconstitute the fricition means to graspthe guiding portions ofthe-track.

I-t-is observed that since theedge-ofithe fabric A lies within the channel member-:58 and isth-us-recurved uponitself-no amount ofstrainupon the fabric in stretching it can possibly withdraw it from said member B'besidesthe fact that the channel members C also assist inpreventing such an occur- 'rence.

The structurethroughout is quite simple and the act. of assembling its parts and stretching the fabric is really more simple than would appear from the description.

In practice, themeasurement of the fabric when out for use: is such that when the members B are placed upon its'edges and folded over upon it, as described, the measurement between the inner edges of the said anembers B in a folded position (Figs. 5 and 6) will be slightly less than the distance between the inner edges-10f the members C in their assembled relation, so that when drawn to the finished assembled position,

the tight flat fabric is the result. 7

In rewiringthe screen the simple removal of the four screws and the spreading of the corner braces permits the members G to be withdrawn whereupon the membersB can be removed and thus readily slipped from the edges of the fabric. A new piece of fabric having been cut in the, manner explained can then be employed'and the parts reassembled.

The thickness ofthepa'rt H of the track E, Fig. 10, has purposely beenexaggerated as well as the part corresponding to it in Fig. 1%, in order that thedrawing can be easily read and that the --str u'cturescan be more readily-observed. However, in practice,;the meeting rails of the upper and lower screens can lie quiteclose together by makingthe equivalento-f the-said portion quite thin. Butwhere a space may exist betweenthem such as would admit insects to crawl between the rails the metal of the member C of the lower screen may be'turned outwardintoa flange C, Fig. 6, to meet the opposite lower railofthe. upper screen-, or, as shown in Fig. 8, the edge of the member C of the lower rail of-the upper screen may be outwardly bent in the same manner toward thelower rail as shown at C .But in any event the braces D willlie close enough to one another for all purposes.

In Figs. 8 and-11 the sides for" the members B and G are corrugated. 1 This answers two purposes, first,v that of strengthening sai m eeb re seerees iesrhe ae b e out of shape by blows that said members may accidentally receive, and second, when the members B are forced into the members C in the manner already explained, the corrugations will aid materially in preventing movement of the parts relatively. However, for the latter purpose the parts may be otherwise provided with roughened surfaces not necessarily coming under the head of corrugations.

The structure described herein. may be employed equally well for half length screens or those to extend the full length of the window and hung from the top to swing outward. In the two piece form herein illustrated the screens because of their thin form can be placed between the window and outside blinds so as not to interfere with either which is'an advantage well understood.

A point of advantage also is that the parts of the screen, besides the fact that they can be easily taken apart and reassembled, are not liable to damage in so doing whereas in some forms of patented devices with which we are familiar the parts cannot be separated without destroying their utility.

The fact that the sides of the members B lie close together or so close as to just receive the thickness of the fabric and that the sides of the members C are spaced just sufficient to receive the said members B and the additional thickness of fabric at the side as in Fig. 12 insures a strong rail for the screen at all sides in addition to the fact that the fabric is so firmly held that it cannot become loosened, aided by the sharp turn of the fabric over the edge of said members. B.

While we have described a peculiar manner of constructing the portions of the screen they may be altered in various ways to suit the desires, or to best meet the aim of the invention, all without departing from the spirit of said invention and the meaning of the appended claims.
