WINDOW-SCREEN.

I Specification of Letters Patent.

Patented Feb. 19, 19158.

To all whom it may concern:

Be it known that-I, ARTHUR'C. Scorn, a citizenofthe United States, and a resident of the city and county of San Francisco and State of California, have invented new and useful Improvements in lVindow- Screens, of which the following is a specification.

This invention relates to improvements in window screens and more particularly to the structure of, and the means for combining the screens with the window frame.

Among the objects of this invention are:

To produce a sightly screen for windows which can remain a permanent-fixture, easily operated or removed and which permits easy access to the Window sashes for opening, closing or washing the same, irrespective of the particular type'of sliding or casement sashes;

To provide a screen which can be applied to the face of the window casing or within the inclosure of the same; I

To provide a screen which can he slid to the top of the window casing, to leave the lower half of the casing unscreened or viceversa; I

To provide a'screen the members of which are so hung that they can he slid up and down in the vertical plane or independently swung outward on their pivots fromthe plane of the window casing;

To providea screen comprising a plurality of overlapping frames, pivoted and guided within a single slot or groove in each side of the window casing;

To provide a screen which will permit'free access for the opening and closing of the window sashes, with the minimum opening of the screen, to'reduce the possibility of flies or insects entering while the screen is thus opened;

To provide a screen with all the foregoing and other advantages, which will operate between the window casing and theconventional shade or curtains usually attached to windows;

To provide means for stretching and securing the screen netting to its frame by positive and permanent means, which will geous features which, with the foregoing,

will be set forth at length in the following description, where I shall outline in full that form of invention selected for illustration in the drawings accompanying and forming part of the present specification. The nov city of the invention will be included in the claims succeeding said description. From this, it will be apparentthat I donot restrict myself to the showing made by said drawings and description, as I may adopt many variations within the scope of my invention as expressed in said claims.

In the drawings:

Fig.- 8' is a plan view from above of a fragmentary section of one side of the window casing showing the screen applied to the facing of the window frame.

Fig. 3 illustrates a modified application of the screen showing it inclosed within the opening of the window casing, said figure being so positioned with respect to Fig. 3' as to showthe proper relation between the modified form of screen and the frame illustrated in said Fig. 8. V

Fig. 4 is a fragmentary isometric perspective of the upper and lower edges of the respective screen frames, illustrating the manner of pivoting the overlapping frames in a single groove. 1

Fig. 5' is a similar view of the upper corner of the upper screen frame illustrating the application of the sliding spring pivot.

Fig. 6" is a side elevation partially in cross section of the spring pivot on the upper screen frame.

Fig. 7 is a fragmentary plan view from above'ofthe guide strip, having a guiding groove therein, into which issecured the i stop head for the lower screen frame. This view is partially in cross section, taken on' In detail, the construction consists of, a

conventional window casing structure, comprising the rabbeted j ambs 1, top plate 2,.the sill 3, the stoolt and the usual facings 5 and 6, stops parting beads, etc., consistent with the type of Window to be accommodated; for convenience in description this structure will hereinafter be referred to as the window casing.

The window casing is provided with the screen guides 77- on both sides of the easing. These guides can also act as stops for the window sashes when properly applied. These guides are provided with a groove 8.

The screen comprisesv preferably two frames, upon which the netting 9 is stretched. The two top corners of the top screen are provided with sliding spring pivots comprising the pins 10, having the oblong friction shoe or head 11 pivoted thereon.

The pins are surrounded by sleeves 12', having'one end crimped or turned in as at 13, to form a seat or abutment for the end of the coil spring 14, encircling the pin within the sleeve and expanding between the abutment 13 and the head 11 on the pin.

The heads 11 project beyond the lateral edges of, the screen frame a distance a trifle greater than the depth of the grooves 8, 4O

whenthe screen frames arein operative po sition in the casing.

The screen frame A, is assembled in the casing by inserting one of the heads 11 into 7 the groove 8, then tipping the plane of the screen horizontally, at an angle to the vertical plane of the groove, to permit the second head 11, to engage the groove on the opposite side of the casing, the. screen frame is suspended within the casing by the frictional upper corners of the frame B, in the, most.

desirable manner. The offset of the spring plate 17 is sufficient to allow the screen'B, to slide over the frame A. The spring tension of the spring plate 17 causes the heads 15 to frictionally engage the grooves 88; thus suspended, both frames are free to i swing outward from the plane of the window casing, as illustrated by dotted lines in 1,25e,sss

. rests upon the stool 4:, behind the stop-fixtures '19 fixed upon opposite sidesof the casing and abutting the stop head 20; thus constructed and assembled, the screen completely closes the opening of the window casing, to prevent the entrance of flies and insects, which is the primary function of the screen, when the window is open.

To permit easy access for-them'anipula: tion of the .window'sashes, the frameB can be lifted by the handle 21, over the stop fixture 19 and'lowered to the position shown in A Fig. 1 to permit access to the'latch 22, in

the instance of a casement window or the frame A can be swung outward to permit access to the fixture 23, in the instance of a sliding sash window as illustrated in Fig.

2. The frame A can be lowered down he I hind the frame B orthe frames maybe placed in many obvious relations to each other and the window casing. During the winter months when insect pests are not prevalent both screen frames can easily be removed and stored away without leaving any unsightly attachments to disfigure the casings. The guide strips are of such simple construction that they are scarcely distinguishable from the molding trim of the window casing.

' It is preferableto mount the screens on the interior side of the casin to make their'application universally possible, irrespective of the form of sash, except in rare instances when casement or otherv forms ofsashes may project into the room, when in the open position, then the screen can be placed on the exterior of the casing.

The available space on the interior side of a window casing is limited; therefore the type of screen frame indicated by this invention must be relatively thin, compact, light, well fitted and sightly.

The mechanical construction of the screen frame hereinafter described, fulfils the most exacting requirements of this art. The frames are composed of the wooden strips 2%, cut to lengths,;to form whenjoined, rectangular frames,approximately the conven-.

tional sizes of window casings. Mounted in the facing of the wlndow casing as in Fig. 3, therange of variable widths of screen,

with respect to the widths of the window casing is considerable, which permits the screens to be made up in stock sizes; whereas the type illustrated in Fig. 3 does not admit of such a wide variation in the relative sizes of casing and screen; some adjustability can be provided for in this type, by making the guides 7, deep enough to permit of ripping off the excessive material in fitting the screen to the window casing.

The various steps in producing a screen frame in accordance with this invention, are substantially as follows:

First: The strips 24 are provided with the saw kerf or groove 25, then mitered or otherwise joined at the four corners of the frame, so that the kerf 25 extends around the frame, a suitable distance back from the inner edge.

Second: Cut blanks of netting 9 of a dimension insuring that the edge thereof extends down into the kerf and part way back, are laid upon the frame.

Third: The angular metal reinforcing strips 26, provided with the barbs 27, struck therefrom, are disposed on top of the'netting, the flange 28 coinciding with the kerf 25. The 'securing points 29, also struck from the body of the strip serve the double purpose of leveling the strip to maintain the flange in the plane of the kerf and to secure the strip to the wood when forced into it.

Fourth: Thus assembled the reinforcing strips are forced down by a press or otherwise, so that the flange 28 carries the slack of the edge of the netting into the kerf, the barbs preventing the netting from slipping; whereby the netting is stretched taut in all four directions at once, insuring a drumlike tightness. The barbs and the securing points enter the fiber of the wood and the flange 28 wedges into the kerf, all cooperating to secure the strips to the frame, which is materially strengthened by the addition of the reinforcing strips; but the reinforcing strips can be dispensed with, the netting being retained in the kerf by its own engagement therewith.

Fifth: Toadd rigidity and finish to the frame the corners are reinforced by an angular metal plate 30, bent back upon itself and having the angles 3. struck up therefrom, to inclose the corner of the frame to which it is attached by the rivets 32 or otherwise. The return bend of this plate is provided with ahole to receive the leeve 13 or with screw holes, to receive the screws 3% for securing the spring plate 17, as the case may be.

Having thus described this invention, what is claimed and desired to secure by Letters Patent is:

1. A window screen including, grooved side guide-s attachable to window casings, a

screen frame, resilient pivots attached to the opposite upper corners of said frame and slidable in said grooved side guides.

2. A window screen including side guides attachable to window casings, a screen frame, resilient pivots attached to the opposite upper corners of said frame, friction members attached tosaid pivots and slidable in said guides.

8. A window screen including, side guides attachable to window casings a plurality of overlapping screen frames, resilient pivots attached to the opposite upper corners of each of said frames and slidable in said guides.

4. In combination with a window casing having a single guide on each side thereof, a plurality of overlapping screen frames,

and yieldingly supported pivots on the opposite upper corners of each of said frames vertically slidable in said guides.

5. A window screen including grooved side guides attachable to window casings; a screen frame; yieldably supported pivots on said frames frctionally engaging said guides; a second screen frame overlying the said first mentioned frame, and having extension pivots frictionally engaging the same groove that guides said first frame.

6. A window screen including grooved side guides attachable to window casings, a screen frame, a friction shoe slidable in the groove of said guide and having a stem engaging said frame, a resilient member interposed between said shoe and frame, and a pivot on the opposite side of said frame slidable in the guide on that side of the window casing, a second screen frame overlying said first frame and having an extension spring pivot engaging the same groove that guides the first frame.

7. In a window screen a frame composed of four strips joined at the corners, a groove in the face of said frame, a sheet of netting having its edges confined in said groove, angular metal strips having a barbed flange edge forced into said groove on top of said netting, and metal corner plates attached to said frame overlying the adjacent ends of said metal strips and inclosing the edges of the frame at the corners.

In testimony whereof, I have hereunto set my hand this 24th day of May, 1913.
