SCREEN REPAIRING DEVICE Filed Oct. 22. 1929 INVENTOk 141 BY iTTORNEY Patented Feb. 17, 1931 PATENT o FFICE- NAT LITWIN, or BROOKLYN, NEW Yoax SCREEN-REPAIRING T DEVICE Application filed October 22, 1929. Serial No. 401,576.

This invention relates to screen repairing devices and is particularly directed to a device for repairing punctured wire window screens and the like devices and to the 5 method of making suchdevices as salable articles of manufacture and to the method of repairing screens by use of such devices. An object of this invention is to provide a neat, compact and rugged device of the 10 character described which shall be inexpensive and simple to manufacture, easy to apply and positively secure to a punctured )or torn screen and which shall yet be practical and efficient to a high degree in use. I Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of 20 elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

. In the accompanying drawing, 1n WhlCh is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a front elevational view of a w 1n dow screen with repair devices embodying the invention applied to intermediate and corner portions thereof;

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1; I

Fig. 3 is a perspective new of a repalr. device embodyin the inventlon adapted to be applied to an Intermediate portion of the screen;

Fig. 4 isa fragmentary perspec t1ve V ew of a repair device embodyin the lnvent on but illustrating a modifie constructlon thereof; and I Fig. 5 is a top plan v1ew of woven screen material illustratmg an intermedlate step in the manufacture of the repair devices.

Referring .now in detail to the drawing,

designates a window frame in whlch is mounted a screen 11 comprising a screen frame12 and screening material 14 secured thereto as by a molding-30. The screen is illustrated as having an intermediate hole extending in the plane of the patch and somewhat beyond the end wires 18a transverse thereto. Extending from said portions 19 are outer free end portions 20 bent at substantially right angles to the plane of the patch as clearly illustrated in Fig. 3.

A few drops 21 of solder or the like material may be applied adjacent the edges of the patch to bind the wires extending in one direction to the wires extending in the transverse direction. This construction serves to stiffen the patch and prevent distortion of.

the device as for instance, when the pressure is applied thereto on a bias;

The application of the device 17 to the screen 11 will now be obvious. The patch is merely placed over the opening or perfora-' tion in the screen to suitably cover the same, and saidpatch is then pushed against the screen so that the free end portions will project through the openings in the screen. Said free end portions are p'refer-, ably then bent outwardly into contact with, the opposite side of the screen to firmly secure said patch to the screen.

The upper right hand corner of Fig. 1 I

shows a patch 17a applied to a corner of the screen, the molding being partially broken away to more clearly disclose the structure.

For forming a patch adapted for attachment to the screen adjacent the edge or corner portions thereof, the extensions 19, 20 are preferably severed or cut away from the edge per tions of the patch which are adapted to contact the edges of the screen, thus leaving a flat edge portion which is adapted to underlie the molding. Thus the patch 17a is provided with two flat edge portions 31 and 32 project thru the screen openings whereby said which may be placed under the molding, the patch may be pushed into contact with said other two edge portions of said patch being screen. formed with said projections 19, for at- In testimony whereof I afiix my signature. 5 tachment to the screen. I NAT LITWIN.

In applying the patch 17 to the screen, should two adjacent end portions 20 extend thru a single opening in the screening material, distortion of the patch will be prevented I I 4 y 10 since the'portions 19 extending from said ad- I I I I i I j acent free end portions 20 may bend toward each other upon pressing the patch against said screen.

Fig. 5 illustrates one method of fabricat- '15 ing the patches 17. The screening material I 40 It will thus be seen that there is provided a shown by full lines insaid figure are woven by any suitable method to form the pattern shown comprising rectangular interwoven I screen wire portions 18 interconnected and I 7 spaced from one another by horizontal wires I I 35 and vertical wires 36. These parallel I I wires 35, 36 may then be cut mediatel the ends thereof along the dot-dash lines s own in Fig. 5 to form separate pieces from which a I I 25 the free end portions 20 may be bent by an I i no suitable means to form the patches. I 1 I I r I *In accordancewith the modified construction 'shown'in Fig. 4 the looped end portions 37 shown in Fig. 5 and formed in the weav-- ing of the screening material, are not cutyto I form separate end portions, but are bent at I I I I I right angles to the plane of the patch 17 6. Furthermore said looped portions are preferably bent inwardly as at 38, 39 to form rugged looped legs 40 adapted to project through the screen 14 upon'ap'plying the patch'to said screen to cover an opening therein, in the manner described above.

device in which the several objects of this in vention are achieved, and which is well adapted to meet the conditions of practical I use. I I II I I I 45 As various possible embodiments might be .1 i I I no made of the above invention, and as various 4 changes might be made in the embodiment set' forth, it is to be understood that all matterherein' set forth or shown in the accompanying drawing, is to be interpreted as il- I lustrative'andnot in a limiting sense.

' Having 'thus described my invention 1 I claim as new and desire to secure by Letters I Patent:

1. As an article of manufacture, a device for repairing screens, comprising a patch of woven screen wire, extendinglooped portions of said woven wire constituting means for at- I p I I I I I 60 taching saidpatch to a screen.
