My invention relates to `windowscreens comprising sections which are slidably oon-` nected for adjustment to litinwindow open-` ings of different widths, and 'has reference more particularly to the manner `of fastening the screen wire into the screen frame.

n'screens` of this character, light wooden frames areemployed `in which the screen wire is secured,and the side strips or stiles of 1o one section are slidably'connected with the side strips or stiles of the other section, the screen wires of the sections being overlapped, andthe overlying edge of the screen wire `of each 'section being secured to a cross brace or edge binding member whichV extends be tween the Stiles and serves as a filler between the screen wire of the sections to close the gap therebetween:

The screen wire is preferably secured tothe stiles with a strip, preferablyintegral with the stile, overlying the edge portion ofthe screen Wire and fastened down to the stile with fasteners which engagethrough'the edge porliso tion of the screen wire. This stripis usually quite'thin and arranged at the side of the stile next to the stile of the other section with which it is slidably connected, andthefasteners are `inserted therethrough from that side. With ythis construction vit is not only desirable to employ fasteners whichxwill hold the strip andedge/of the screen wire securely `in place,

`but it is also important to provide fasteners of suitablecharacter and `arranged in such a manner that they will not at any time annoy the user or subject the 'light frames to excessive strains by catching or interfering with the free andeasy sliding operation of the sections. This is accomplished in my present construction by using staples to fasten the strips in place, and the staples l are not only arranged' diagonally to therline vto `of movement of the sliding sections but the staples of the two stiles which are slidably connected, lare arranged in opposite diagonal directions to the line' of slidingmovement, so that they-approaclifone'another at a suitable angle to facilitate passing and to avoid interference with one another and cramping in the sliding engagement of the sections. This also, affords an arrangement `whereby the staples straddle the grain of with the two prongs of the staple located so Las to give a double connection of maximum in place; to avoid interference by the fasteners in the sliding movement. of the sections;

to arrange the fasteners so thatthey have a reciprocal guiding action in passingyand in general to provide al simple, convenient `and economicalfastening for accomplishing the above objects. f

similar to that of Patent No. 97 2,481, of October 11, 1910, to Sprague, and comprises two sections 1 and 2 of screen wire supported in Vseparate frames which are slidably connect ed, with the screen in sections 1` andQ over l lapping, to vary the size of the screen to tit in different window openings.

VThe frame of the screen section 1 comprises two Stiles 3-3 connected at their outer ends to an end rail l in any convenientmannen and theframe of the screen section 2comprises the stiles 5&5, which are likewise con nected at their outer'ends to theend -rail 6. The frames of the two seotionsareoflike widthand length, and havetheirv stiles formed ,for sliding. interengagement, the stiles 5 being provided in the inner faces,neX t to the The screen shown and described hereinis 2 `Bnn'r n. HINKLE, on HILLsnAILnfMIonIGAN, Asssrelvon` To HILLSDALE scnnnnV OOM- the` wood *ciu stiles 3 with longitudinally extending rab bets or grooves 7 having an undercut recess 8 as illustrated in Fig. 4, while the stiles are provided on the inner faces next to the stiles 5 with a longitudinal rib 9 fitting to slide freely in the groove or channel 7 and a laterally extending i'iange 10 lil-rewise fitting in the under cut recess 8 of the stile 5. 'Ihus when the inner ends of the two frame parts are brought together, the ribs and fianges 9-10 will fit into and slide within the corresponding grooves and undercut recesses 7 8, the engagement of the fianges 10 in the undercut recesses 8 preventingthe two frame parts from separating laterally and the ribs 9 in the grooves 7 holding the frames in constant parallel relation.

For securing the screen wire sect-ions 1 and 2 in the frames, the inner edge of each of the stiles 3-3 and have formed therein a deep narrow slot or lerf 11 adapted to receive the edge of the wire screen cloth. These slots or kei-fs, which are merely wideenough to receive the edge of the screen wire freely therein in assembling, are located quite close to the inner er adjoining faces of the stiles 3 and 5, so as to provide a thin lip or strip 12, which is adapted to be clamped down by suitable fasteners against the screen in the slot or kerf 11, and to provide a definite lineI along which the lip 12 may bend when clamped down and to avoid breaking or splitting of the wood at undesirable places, the lip is preferably scored at 13 along the inner extremity thereof or at the inner edge of the slot or lerf 11 shown in Fig. if.`

The fasteners for securing the edge of the screen wire in the slots 11 are passedthrough the lips 12 from the inside to anchor the ends thereof in the thicker portion of the wood and also to avoid impairing the outer finn ished surface of the screen. The inner ends of the fasteners are therefore located on the contiguous sliding surfaces of the screen frame sections. and if not fully driven in, or if they loosen up, are likely to VAcatch and interfere with the desired free and easy sliding movement of the frame sections, thereby f causing annoyance and imposing excessive strain on the light marginal frames.

In order to insure a more substantial fastening of the screen wire in the frames, and to avoid catching` of the fasteners even though they are not fully driven in. or loosen up somewhat. I employ staples 14 and 15 respectively on the sections 1 and 2 which are wide enough to straddle a substantial portion of the lip 12, and I arrange these staples diagonally so that the loop or bight portion 16 extents across the grain of the wood with the prongs 17 thereof in different strata to minimize the danger of splitting.

Moreover I arrange the staples lll and 15 of the two adjoining stiles in opposite diagonal directions as shown in Figs. 1 and 6, so that in passing over one another they do not approach and pass in parallel relation but at a suitable angle as shown in Fig. 6, so that the corresponding ends come together first. The staples are formed preferably of round wire, and in bendino the prongs or arms 17 downwardly from the center or bight portion 16 and driving the staples, round bends 18 are formed at the corners and the center portion usually arched somewhat as shown in Fig. 7., so that the ends of the bight portion 16 or corners 18 are usually pretty well embedded in the lip 12, and by arranging the staples of the two stiles in opposite diagonal directions the rounded and depressed portions 18 of the opposite staples come together first, so that they start to pass quite readily even though the staples are not fully driven in, and the criss cross or angular arrangement of the bight portion 16 affords a reciprocal guiding action to facilitate passing of the staples over one another.

The screen wire may be secured to the end rails 4f and 6 in any convenient manner, for example by inserting in a slot 19, the ends of which receive tenons of the stiles 3 or 5 with a strip 20 filling in the eXtra space in the slot between the stiles and held in place by fasteners 21 which pass through the end portion of the screen wire in the slot. The remote edges of the screen sections 1 and 2, which overlap one another, are each confined in a folded metal marginal binding strip 22, the

ends of which are secured in the kerfs or slots 11 of the respective stiles 3-3 or 5 5 to afford a cross brace for the frame, and the portion of this marginal binding 22, between the stiles is bent into an angular form as shown in Fig. 5. to stiffen the cross brace and afford a flange 23 to close the space between the screens and prevent insects entering therethrough.

With this construction the screen wire not only may be securely fastened in light wooden frames, but the annoyance and excessive strains occasioned by the fasteners along the stiles catching and interfering with the sliding of the sections is avoided, as the fasteners ride over one another freely and easily even though they are not fully driven in or have pulled out slightly.

While I have shown and described my invention in a preferred form, I am aware that various changes and modifications may be made Without departing from the principles of my invention, the scope of which is to be determined by the appended claims.
