SCREEN CLOTH Filed Nov. 21, 1935 FIG. 6 BY flw ATTORNEY Patented 4, 1937 v UNITED STATES PATENT OFFICE 2,078,940 scans: cLorn John J. Grebe, Midland, Mich., assignor to Ewing Development Company, Bay City, Mich., a corporation of Michigan Application November 21, 1935, Serial No. 50,879 6 (Cl. 245-4) This invention relates to an improved screen tween about 0.007 and about 0.015 inch in diamcloth adapted to be used particularly on the wineter. Carried between said wires 1 are crimped dows of dwellings, ofllces, etc. ribbons so arranged that the horizontal portions It is the principal object of the invention to 8 thereof are all parallel to each other. The disprovide an article of manufactu'rewhich will pertance between adjacent horizontal members is 5 form the function'of an ordinary window screen between about 0.040 and about 0.100 inch. Prefcloth, 1. e. to prevent the ingress of insects, and erably this distance is about 0.050 inch. The ribwhich will also be capable of functioning in such bons constituting the horizontal members for this manner as to exclude the direct rays of the sun screen section are made by crimping a flat strip from the interior of a building. j of metal, preferably between about 0.002 and 10 It is another object of the invention to provide about 0.005 inch in thickness by 0.025 to 0.10 an improved window screen cloth which will adinch in width,v to form a member provided with mit of materially greater vision than does the substantially parallel sections 8 about 0.0625 inch present commercial screening. in'length, and substantially'parallel sections 9 To the accomplishment of the foregoing and about 0.050 inch in length, connecting said first related ends, the invention, then, consists in the portions, the two sections being at right angles to manufacture hereinafter fully described and pareach other. These crirnped members are then ti'cularly pointed out in the claims, the annexed placed between the vertical wires 7 and permadrawing and the following description setting nently fixed thereto by hot tinning or galvanizing. go forth in detail certain means for carrying out In the event that it is desirable to use flat rib- '20 the invention, such described means illustrating, bons as vertical members they are preferably of however, but several of the various ways in which the same dimensions in cross section as the ribthe principle of the invention may be used. I bons employed to form the horizontal members of v In said annexed drawing: this screen section. Such flat vertical members Figure 1 is a frontelevation of a section of one would, of course, be incorporated into the screen form of my improved screen cloth; Figure 2 is a cloth with their major surfaces perpendicular to side elevation of the screen section shown in Figthe plane of the screen. ure 1; and, Figure 3 is an end elevation, looking In Figures 4, 5,-and 6 the horizontal members up, of the screen section'shown in Figure 1. l0 are flat ribbon-like metal strips extending the Figure 4 is a front elevation of a section showentire width of the screen section.

These members iii are substantially ure 4. parallel and regularly spaced apart the same dis- My improved screen cloth comprises, essentances as the horizontal portions 8 of said tially, spaced. substantially parallel, vertically crimped ribb n. These members ID are held in extending members which may be of circular or position by spaced substantially parallel vertical other desirable shape in cross section, and spaced, members each comprising two strands of wire i i 40 substantially parallel, horizontally extendingv and I! which preferably cross each other between 40 members having an elongated cross section, the each horizontal member ID. major surfaces whereof are inclined to the plane When the plane of the major surfaces of the of the Sc een. normally being perpendicular horizontal members in my new screen cloth is thereto but may be inclined downwardly and substantially perpendicular to the plane of the outwardly fmm such perpendicular at any angle screen, such cloth is particularly adapted to be thereto up to about cross Section of the used on screen frames set in windows with a i gg g g' 33 52:33? ism 'ggf z 1: southern exposure.

In these n is preferably below 1 to r n w i h th plane ures the vertical members are illustrated'as round of the major surfaces of the horizontal members 55 wires, and in practice I prefer to use wires bein the screen is inclined down and outwardly at 55 an angle of up to 45 from the perpendicular to the plane of the screen.
The effect of my novel screen cloth inusage'is to reflect and absorb thedirect raysof the sun,
thereby excluding such rays from the interior.
To increase the absorption of the :rays -of the sun, my screen cloth is preferably given a black etched finish. This may be done,'for example, bytreating the tinned surface of my screen section with hydrogen sulphide fumes.
The ratio of the thickness of my improved screen to'the vertical distance between thehorizontal members thereof is preferably not less than 1 to 2 and preferably not more than-2 to 1. This I,
is an essential requirement, because if the thickness of the screen is less than one-half the vertical distance between the horizontal members of the screen, the screen will not functioneffectively to exclude the rays of the sun, while if thethickness'of the screen is materially more than twice the vertical width of the openings therein, the degree of visionis lessened to an undesirable point when it is desired to see therethrough at somewhat of an angle to the perpendicularfrom the vertical plane of the screen as normally used. While screens of the type and form hereinbefore described can be made with spacing between the horizontal members less than the dimensions above given, such aregenerally undesirable, because of diifraction eifects which cause images to be blurred through the screen so that a person looking therethrough sees two or more outlines of the same'object. I In practice, I have determined that the per cent open area for vision in the plane of the major surfaces of the horizontal members of my screen cloth .isapproximately 95 per cent, while the open area for vision in ordinary commercial screening is only about 75 per cent. I
Other'modes of applying the-principle of my in- 1 vention may be employedinstead of those explained, change being made as regards the manufactureherein disclosed, provided the means stated by any of the following claims or the equiv- I inclinedto the plane of the screen, said members being spaced apart less than twice the width I thereof.
