ADJUSTABLE WINDOW sonnnn;

Application filed May 24,

This invention relates to Window screens, and more particularly to a novel improve ment in screen frames whereby a frame of standard size may be readily adapted to fit standard window openings which may vary slightly in dimensions. V

, In the fitting of screens that cover the en tire window opening it is usually necessary to make or build each screen to fit a particular Window frame due to the fact that the frame of one window may have warped a little or was not finished to precisely the same width or height as another although all of the windows may have originally been standard stock sizes. Or perhaps, the trim of window frames made by different mills will vary one-half to one inch in size. Therefore, it is difiicult if .not impossible to make a screen frame for stock purposes that can be used without considerable cutting, planing and fitting to make a snug fit between the screen f ame and the window. frame.

Accordingly, one of the objects of the present invention is to provide a construction which includes a rigid and substantial main frame having means whereby the screen may be made to fit accurately within a window opening that is larger than the frame without the expenditure of time and labor in fitting the same. That is to say, the present invention contemplates, as its primary object, the provision of adjustable means on the screen frame adapted to be interposed between the frame and the window opening, and adapted to be automatically set bythe mere act of placing the screen in the Window opening.

A further and more specific object of the invention is to provide a novel substantial metallic filler and adjustment member which may be readily and economically manufactured and easily applied, thereby materially enhancing the value of the invention from a practical standpoint.

A further object of the invention is to provide novel means for covering the joint between the a combined filler and adjustment members. f

With the above and other objects "in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of 1927. Serial in. 193,837.

the inventionis shown in the accompanying drawings in which: v

Figure 3 is an enlarged detail perspective view of a corner of the screen construction, showing the corner clip detached.

' In carrying the invention into effect, it-is proposed to provide or equip the screen desig nated" generally as E with a. novel edge-construction for adapting the sameto variations in the window opening, thereby avoiding the necessity of building up the window frame or cutting and fitting the screen to each particular window. This feature has the ad vantage of permitting the screen to be readily made to fit a window opening even though it is not entirely true, without the aid of special tools.

Accordingly, as will be observed from the drawings the screen S includes a rectangular frame 1 which may be made of metal or wood and has the wire mesh portion 2 secured there to in any convenient and suitable manner. The screen shown in the drawings is of the swinging type, that is, the type which is hinged, one end to the window frame and swings into the window opening from the outside of the window, the hangers- 3 being provided at the top of the frame for that purpose. At all sides the frame 1 is provided with acombined filler and adjustment strip designated generally as 4, the said strip being movable with reference to the outer edge of the frame 1 in such a way as to provide ineffect an extensible and contractible edge portion for the frame. l

As will be observed from Figure 2, the said strip et'includes a body portion having the offset flanges 5 and 6, the flange 5 being secured to the rear side of the frame 1 by the fastenings 7, and the corner 8 between the flange5 and the body constitutes a hinge. I The'other flange 6 is provided with a sliding angularly disposed portion 7 which frictionally engages the outer face of the frame 1. The flange 67 is wider than the flange 5 which is anchored to the frame, and, therefore, the body 4 of the Combined filler andadjust'nient strip may. have a fairly wide range of movement between the outer face of the screen frame 1 and the window opening It will thus be seen that the nose or corner:

9 between the flange 6 and the body 4 constitutes a window frame engaging edge which is formed by the meeting inclined body portion t and flange 6. Before the screen is fitted to the window frame, the member a is plulled outwardly so'that the portion 7 of the y ange 6 engages the frame 1 near its outer edge. .lVhen the screen s placed inthe win-- dew and swung into the frame, the inclined body at will strike the outer edge of the window frame and move the entire stripinwardly toward the frame untilthe nose 9fslidably engages the inside of the Window frame. The force of the frictional engagement be tween the flange 67 and the screen frame willhold the strip 4 in the proper set position so thatthe entire screen will properly fit all edges of the Window opening, and in that I way, the entire screen will become automati cally fitted in place.

The ends of each stripe are cut square rather than mitered because a miter would leave'a gap if all of the strips were not coinpressed to their fullest extent. And, in order to fill the gap at thecorners and thereby'sd cure a tight corner joint, a corner slip '10 is provided. This clip is carried by the vertical or sidestrips at each end thereof, and as shown "in Figure 8 is of substantially U- shaped formation, so that it may frictionally and telescopically engage the ends of the strip tobe adjustable thereon and thus completely fill the gap between the meeting edges of the strip members. Therefore,it will be apparent thata-deq'uate means is provided for rendering the screen tight atthe corners as Well as atthe side and 'end edges. It. will of course,"be understoodthat the clips 10 are of less width than the width of the flange 6. so that when the, strips 4 are compressed they will notinterfere withthe lateral adjustment of the strips, and of course, since they tele I window opening.

scopically engage the strips they will be readily'adjustable lengthwise to enable the screen to adpist itself to the vertical height of the From the foregoing it will 'be apparent that a distinctive feature of the present in- Vention resides the provision ofa substantially channel shaped fillerand adjustment strip comprising a bodyhaving offsetflange portions, fone of which is secured at or anchored .to the screen frame and the other of which frictionally and adj ustably engages theouter face of the screen frame. The adjustable filler strips 4: are preferably made of metal with sufficient. inherent resiliency to keep than in extended or projected relation with reference to the screen frame to properly I signature.

I .Without further description it is thought that the features-and advantages of the invention. will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resortedto, without departing froi'n'the spirit of the'inv'ention' and scope of the appended claims. v I
