4 Claims.

This invention relates to insect screens, and relates more particularly to insect screens made of artificial organic materials.

Insect screens have heretofore been made of wire cloth, i. e., a fabric of woven metallic wire, normally stretched in and affixed to a frame and hung in windows of homes, automobiles, trailers or wherever it is desired to prevent the entrance of insects such as, for example, flies and mosquitoes. Such screens are often' wound on rollers and operate in the same manner as a window shade except that the side edges of the screen are contained in and slide within slots formed of spaced wood or metal strips. The wire cloth suffers from the serious disadvantage that it rusts or-weathers in use, thus marring the appearance not only of the screen itself but also of the structure upon which it had been hung. Wire cloth screens require frequent painting to give them a neat appearance.

It is an important object of my invention to provide an insect screen which will be free from the above mentioned and other disadvantages and which will be efflcient in operation and inexpensive in cost.

Another object of my invention is the provision of a novel insect screen made of heavy denier filaments of artificial organic materials,

which filaments are strong, flexible and substantially resistant to weathering.

A further object of my invention is to provide an insect screen made of artificial filaments of organic material which filaments are transparent to translucent whereby at least .some light will pass therethrough.

Other objects and advantages of this invention will appear from the following detailed description.

The figure of the accompanying drawing shows diagrammatically insect screening of the present invention.

In accordance with my invention, I make insect screens from open texture fabrics which are formed by weaving or netting relatively stifi artificial filaments of heavy denier. The openings in said fabric may be formed in any shape ting to the frame.

place of nails or staples for attaching the net- If desired, the periphery of the sheet of netting to be applied to the frame may be reinforced by applying thereto strips of cloth or of any artificial material which in turn may be affixed to the frame.

, To prepare the netting of the present invention 'monofilaments, or heavy denier filaments, are woven or netted by suitable textile devices into the open texture fabric desired. These monofilaments are transparent to translucent,

relatively still, and preferably have a denier of from 500 to 1000. However, monofilaments of somewhat finer or heavier denier may be employed in making the insect screens of my invention.

I The monofilaments may be produced in any convenient manner. Thus, they may be made by extruding a single filament through a spinning orifice of large diameter or by extruding a number of filaments from a plurality of spinning orifices of small diameter and, while the filaments are still in a sticky condition, associating and physically uniting them into a single filament of heavy denier, or monofilament. Another method of preparing the monofilaments is by passing a plurality of formed continuous artificial filaments, while in a condition to ad-' here to one another, through a die or series of dies of appropriate shape, whereby they are caused to adhere and coalesce together to form a but must, of course, be small enough to prevent insects from passing therethrough. The open texture fabric, which will hereinafter be referred to as netting, is fixed by any suitable means in a frame of a size to fit the window or opening which is to be protected, in the same manner as wire cloth screening is affixed to a frame. In the case of the netting of my invention, however, a suitable adhesive may be employed in single filament of large cross-section. The small denier filaments to be united may be treated with a solvent or softener individually and subsequently brought together, or they may be treated while associated as a' twisted or untwisted thread or as a plurality of threads. The treat ment may be carried out on the filaments while they are-travelling at any convenient stage of their production. Mesh fabric suitable for use as or in screens may also be made by weaving threads made of strips of foil of suitable width and thickness which had been twisted to form a continuous spiral thread. To keep these spiral threads in a set condition the foil is preferably treated with a solvent or softening agent prior to or during the twisting thereof. If desired, the netting, after weaving, may be passed through heated calender rolls arranged to apply a light pressure thereon, whereby the filaments or threads are cemented together at the points where the weft and warp cross.

The material employed for preparing the monofilament or thread from which the insect screens are made preferably has a. basis of cellulose acetate. However, other filamentor foilforming substances may be employed, among which mention may be made of other organic esters of cellulose such as cellulose propionate and cellulose butyrate, ethers of cellulose such as ethyl and benzyl cellulose, esters of cellulose containing inorganic radicals such as nitro-cellulose and nitro-acetate, thiocarbamic and alkoxy alacyl esters of cellulose, condensation products of methylene adipamide.

The materials employed in accordance with my invention may have a plasticizer or plasticizersincorporated therein, particularly where the insect screen is to be mounted on a roller for mm'e. merit up and down relative to the window frame. The addition of plasticizer to the materials makes the same stronger and more flexible. Any suitable plasticizer may be used in such materials among which may be mentioned ethyl toluene sulphonamide, dibutyl tartrate, dibenzyl tartrate, diethyl phthalate, triphenyl phosphate and tricresyl phosphate.

If colored screens are desired for any purpose dyestuffs may be incorporated in the materials. The dyestuffs may be included in the filamentor foil-forming composition before .the products dibutyl phthalate, triacetin are formed or by applyingasuitabie dyestufl to the surface thereof.

The insect screen made in accordance. with my invention retains its original appearance no matter how long it is in use. It may-be cleaned merely by wiping the same with a rag or cloth wetted with water.

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire 'to secure by Letters Patent-is:

1. Insect screen comprising an open texture fabric containing threads made of twisted and adhesively set strips of foil having a basis of an organic ester of cellulose.

2. An insect screen comprising an open texture fabric containing threads made of twisted and adhesively set strips of foil having a basis of cellulose acetate.

3. An insect screen comprising an open texture fabric containing a warp and a weft of threads made of twisted and adhesively set strips of foil having a basis of an organic ester of cellulose, the threads of said warp and weft being Joined together at intersecting points.

4. An insect screen comprising an open texture fabric containing a. warp and a weft of threads made of twisted and adhesively set strips of foil having a basis of cellulose acetate, the threads of said warp and weft being Joined together at intersecting points.
