fly escape.

The invention relates to an improvement in screens and'partlcularly to a screen constructed with a simple and effective form of,

The main object of the present invention'l is theiprovision of a screen embodying practically the usual frame and screen cloth, the frame being peculiarly constructed at the upper end to form an effective fly escape in the screen cloth.

. The invention in its preferred form of de-' tailswill be describedin-the following specification, reference being had particularly to drawings, in which:-'

transverse section on the line-3+3 ofFig 1,

Referr ng particularly to the jaccoinpa'ny-J v ing drawings, my improved screen=ycomprises a' frame including side andend bars land 2, all of which, with theexcepti'on of the upper end bar 2, are of theyusual con struction and form no material part of the present invention. The upper end bar, which has a width corresponding to the similar di-i I mension "of the lower end bar at its rela! tively ment with the 'surface of the adjacent side inner surface, isprojected inaline l bars, as at 3, and from this portion' '3' ,ing,

. clines inwardly Qlj'Present an inclined, S111?" face 4: which extendsyinwardlyand down-n wardly with relation to the relatively outer onscreen cloth receiving surfaceof thes'lfde' 1 bars. The relativeglower edge 5 of the-upper" surface of the side barsandllo'wer end'ibar cross bar of the frame is of appreciable width, being approximately one'ihalf the: thickness of the side bars. i i 1 a k The screen cloth 6 is secured out r in the usual manner, theusual sealing strips p 7 being applied across the inner and preferably extended surfacev of the upper endbar 2 and so complete the configuration. ;In line with the lower edge of thefupperframe I r which has been reduced! bar the screen cloth, in wldth at this point to correspond tothc'j distance between the inner surface ofthe side bars, is bent laterally toi; fo'rm' aledge Copies of this patent may be obtained jf or 1 Specification of Iletters ratent;

and the outer edge of the laterally proje'cted portion is secured beneath the lower edge of the upper frame bar and prefer ably secured thereto by the usual sealing strip 9. "At the juncture of the ledge 8 with the. main length of the screen cloth there are formed openings 10 providing the fly escape openings. 7

The function of the screen in use will be readily apparent from the above description,

Ctalren in connection with the drawings, it

" n VVhat is claimed is LQA screen inclding side and end frame bars, the upper or lower edge of less width than its upper edge throughout the full length of said bar between the side bars and presenting an inclined inner surface leading from the lowerfedge toward the upper edge, the upper edgeiof the screen cloth. being secured beedge throughout i'vthe between the side bars and presenting an in- "fclinefl d innersurface leading ledge toward the upper edge,
