ELMER K. HOLLAND, OF GAL'I, MISSOURI.

SCREEN HAVING FLY-EXIT MEANS.

Specification of Letters Patent.

Application filed August 2, 1916. Serial No. 112,736.

To all whom it may concern:

Be it known that I, ELMER K. HOLLAND, a citizen of the United States, residing at Gralt, in the county of Grundy, State of Missouri, have invented a new and useful Screen Having Fly-Exit Means; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the art of window and door screens, and particularly to a screen particularly adapted for the exclusion of flies and other insects.

One of the objects of the invention is to take advantage of the well known aptitude of a fly or other insect of crawling upwardly upon a vertical surface, and to provide an exit outwardly through which the fly will crawl, there being no entrance through which the fly may return into the room.

Another object of the invention is to provide a frame for a door or window having two or more panels of wire fabric or screening material, the lower edge portion of one panel being rolled or turned upwardly upon the inside, the upper edge portion of the lower panel being rolled or turned downwardly, the two rolled portions being spaced apart to form an exit for the fly or other insect, the upwardly inner inturned portion acting as an abutment to direct the fly in its course outwardly through said exit opening.

A further object of the invention is the provision of a guard angular in cross section constructed from a separate piece of wire fabric and disposed on the exterior of the screen to overlie said exit opening and the exterior downwardly rolled part of the upper edge portion of the lower panel, so as to guide the fly or other insect in its exit course downwardly upon the exterior of the screen.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings and claimed.

In the drawings Figure 1 is a view in perspective of an improved window screen, showing the screen or reticulated material as applied to the frame of the screen, and constructed, whereby flies or other insects may pass outwardly on their upward course.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 illustrates collective views of an upper and lower panel of screen material, showing the same constructed to provide sald exit opening. Referring more especially to the drawings 1 designates a frame and 2 the lower panel of screen material, and 3 an upper panel. The upper portion of the lower panel 2 is rolled or turned outwardly and downwardly upon itself forming a roll 4, and the upper edge portion of the panel of screen 3 is provided with a similar outwardly extending roll 5. The lower portion of the upper panel 3 adjacent its side edges is provided with slits 6, and the portion 7 between the slits 6 at the lower part of the panel 3 is turned upwardly on the intcrior of the screen to form the roll 8. The ears 9 of the lower part of the upper panel of screen material are secured to the frame 1 between the upper side portions of the lower panel and said frame. The two panels of screen material or wire fabric are secured to the frame 1 by the suitable fasteners 10. Also secured by two opposite fasteners 10 is a guard 11, which is substantially angular in cross section and is constructed of suitable screen or wire fabric material, and disposed to extend over and downwardly of the roll 4:. A similar guard 12 is also secured by some of the fasteners 10 to the upper rail of the frame 1, and extends outwardly and downwardly over the roll 5. A fly on the interior face of the panel 2 owing to its well known aptitude, will crawl upwardly, in which case the roll 8 will guide the fly through the exit opening 13, between the two rolls 4. and 8, while the guard 11 will guide the fly downwardly upon the exterior of the screen panel 2. A fly crawling upwardly upon the inner face of the panel 3 will be guided outwardly through the exit opening 14 between the guard 12 and the roll 5, by the upper rail 15 of the frame 1. The guard 12 will then guide the fly downwardly upon the exterior of the screen panel 3.

The invention having been set forth what is claimed as new and useful is 1. In a screen, the combination of a frame and a pair of upper and lower panels of screen material secured to the frame, of a roll at the lower edge of the upper panel on Patented Aug. 14, 1917;

the interior of the screen, the upper portion of the lower panel having an outwardly and downwardly extending roll, said two rolls being spaced apart forming an exit opening, and a guard on the exterior of the upper panel extending over the exit opening and downwardly over the exterior roll.

2. In a screen, the combination of a frame and a pair of upper and lower panels of screen material secured to the frame, of a roll at the lower edge of the upper panel on the interior of the screen, the upper portion of the lower panel having an outwardly and downwardly extending roll, said two rolls being spaced apart forming an exit opening and a guard on the exterior of the upper panel extending over the exit opening and downwardly over the exterior roll, the inner roll acting as an abutment to guide the flies through the exit opening, the edge portion of the material of the outwardly ext-ending roll extending downwardly, whereby a fly crawling upwardly on the exterior of the lower panel will crawl under the roll.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ELMER K. HOLLAND.
