This invention relates to screens for windows and the like. w One of the objects of this invention is to rovide a screen for windows and the like without a 'continuous frame and so constructed and attached as to retain a taught condition of the screen wire without interferin with the upward or downward movement o the window sash.

Another object of the invention is to provide a window screen which shall extend across the full openin of the window and which can be adjusted 1n size.

Another object of the invention is to provide a screen which will extend across the entire opening of the window and which will permit the opening of bot-h the upper and the lower sashes.

Another. object of the invention is to provide a window screen which can be easil and quickly laced in position or remove .and which w en not in use can be stored 1n a very small s ace.

Another o ject is to provide a screen that can be readil ,easily and conveniently placed 'in position rom the inside of the building.

Another object is to provide a screen that will admit the maximum amount of li ht.

Figs. 7 and 7* are views similar to Fig. 4 showing an attachment to the form of window commonly used in brick or stone houses;

Fig. 8 is an enlarged view showing the holding pieces for the sides of the wire mesh;

Fig. 9 is a sectional view taken on line 9-9 of Fig. 8;

Fig. i0 is a view showing another means for adjusting the screen;

' Fig. 11 is an enlarged view of the rotating part shown in Fig. 10;

Fig. 12 is anend view of the rotatable' struction, capable of performing the desired function. In the drawings I have shown these end pieces as consisting of single pieces of metal, the metal of each bent back upon itself, the looped end 6 projecting at an angle from the body portion as shown in Fig. 3. The'wire mesh passes up between the two overlapping portions as illustrated in this figure and is held in position by fastening devices 7 which pass thro h the two overlapping portions of the en piece and may also pass through the holding devices. The outer overlapping part of each end piece iS preferably made longer than the inner, and is bent inwardly as shown at 6 so as to hold that portion of the wire mesh between the two end pieces in substantial ali nment with the inner overlapping member o the top and bottom end ieces so that said wire mesh will engage t e edges of the window frame thus preventing any cracks at the ed es of the screen between the screen and the rame. These fastening devices may be pins, screws, bolts or the like. I prefer to project the wire mesh beyond the fastenin devices 7 so that the screen ma be adjuste for length. If it is desired to engthen the screen the fasten ing devices 7 may be removed and the wire mesh pulled out at one or both ends to secure the desired length. If it is desired to shorten the screen the wire mesh may be pushed in farther. The fastening devices are then replaced so as to hold the parts in their adjusted position. n This adjustment may be made to makethe screen accurately fit the window space, and it may also be made in certain cases Where the screen is somewhat too long to secure the desired tension. In this latter case it will be shortened so that when properly stretched it will close the window space.

Some means is provided for fastening this screen in position. The screen entends across the entire open space of the window and is fastened to the frame as illustrated in Figs. 1, 3 and 4. In the construction shown thetop of the screen is fastened to the upper part of the window frame by suitable holding devices 8 (see Figs. 3 and 5). One form of holding deviceis illustrated in the drawing and consists of a piece `of metal having an opening 9 for a screw, rivet, bolt or the like for fastenin it to the end piece. This piece of meta is bent so as to form the angular section 10, and this angular section is again provided with a bent end 11. The angular section 10 and the bent end 11 are provided with a slot 12 which preferably eX- tends to the end of the bent end 11, the slot having an open end at the end of the piece 11. The holding devices are fastened to the end pieces 2 and 3 by suitable fastening devices which may be the fastening devices 7 and which pass through the openings 9. The angular sections 10 of the holding devices are then fastened to suitable parts of the window frame at the top and the bottom. Some means is provided for holding the screen taught. I secure this result by the construction illustrated in the following manner. The holding devices 8 are fastened to the cross pieces so that the angular sections at one end are separated by a space from the part of the window to which thelyI 'are fastened. Fastening devices 14, whic are preferably screws of some kind are then inserted in the slots l2 and screwed into the frame piece 15 of the window. These fastening devices are adjusted until rthe screen is taught and the parts are made of suchx proportions as to permit this. I prefer to have the angular section 10 bent in such way that the angle between it and the main body of the holding device is less than ninety degrees. 'Iliese holding devices are laced von the inside of the screen so that t e screen may be attached from the inside, and this inclination causes-tlie screen to be diawn inwardly as the screw is tightened down, insuring a tight fit between the end pieces and the edges of the wire mesh, and the parts of the window frame they engage.

When this form of window screen is placed on the usual form of window in a `frame house, the edge of the end piece enmove so as to bring the fastening device 14.

closer to the main body of the holding device.

The face 15 resists this movement and thus a tight t is insured. The tightening of the fastening devices 14 also causes the lower end piece of the screen to move downwardly to secure a taught screen.

When the screen is used in connection with a window like that shown in Fig. 7 I may invert the holding device as shown in Fig. 7 a. By means of this construction the end pieces may be brought near to and below the face of the frame piece 15b, the end pieces being held in position by the holding devices so that said end pieces will not obstruct the light entering the window. The holding devices 8 are also provided at the upper end of the screen and fastened to the upper part of the window frame as hereinbefore set out.

By having slots 12 open at the end, the fastening devices or screws may be left in the window frame if desired when the screen is removed, as it is only necessary to loosen them and then move the screen so that they will come out of the slots 12. Any desired number of these fastening devices may be used. I prefer to have them arran ed say every six inches. In this event t e end pieces 3 may be made up in stock in long pieces and then may be cut in any desired lengths for the screens when they are to be made up, and in that event there will be a suflicient number of fastening devices thereon.

It is desirable particularly with long screens to provide means for holding the wire mesh at the sides. I have shown holding pieces 16 for this purpose. These holding pieces are provided with teeth 17 (see Figs. 8 and 9) which are bent at an angle to the body portion. The body portion is rovided with one or more openings 18 for astening devices 19, for fastening the holding pieces to the window. The openings 18 are preferably elongated openings and the fastening devices 19 are preferably screw eyes. When this construction is used for example, theteeth of the holding pieces may be placed in the mesh of the wire mesh and then pulled over until the openings 18 come opposite the screw eyes. The heads of the screw eyes may be in position to pull under these elongated openings and then the screw eyes are turned so as to hold the holdin pieces in place. Any desired number o these holding pieces may be used and it will be seen that by means of them the screen is held taut against the window frame at the edges.

In Fig. 10 I have shown another arrangemeint for adjusting the screen. In this construction one of the end pieces is provided with a space extending therethrough, and the wire mesh passes into this space 20. I provide in this space a rotatable ieee made up of two sections 21 and 22. 'I is may be a split rod or of any other form. The end of the wire mesh is placed between the sections .and they are then rotated to wind the wire mesh about them. The amount of adjustment of the screen will depend upon the amount of the wire mesh wound about these sections. The sections may be arranged with squared or non-circular ends so that a wrench may be applied to them as shown in Fig. 12. After the proper adjustment is made the fastening devices 7 may be tightcned so as to clam the wire mesh to hold the parts in their justed position.

The invention provides a window screen which is easily adjustable to the space of the window frame and to such space which is usually occupied by a storm sash. The screen also admits a maximum degree of light due t0 the fact that it does not have the obstructing frame necessary with the ordinary screen.

I have described in detail a particular construction embodying the invention but it is of course evident that the parts may be varied in many articulars, without departing from the spirit of the invention as set forth in the claims hereto a pended, and I therefore do not limit mysel to the particular constructipn shown.
