FRANKLIN PEARL KNOVLES, OF DIXON. VYOMING.
FLY-SCREEN.
SPECIFICATION forming part of Letters Patent No. 766,703, dated August 2, 1904.
Application filed February 27,1904. Serial No. 195,592. (No model.)
To all whom, it 721111/ concern:
Be it known that I, FRANKLIN PEARL KNowLEs, a citizen of the United States, residingl at Dixon, in the county of Carbon and State of IVyOming, have invented new and useful Improvements in Fly-Screens, of which the following is a specification.
My invention relates to new and useful improvements in fly-screens; and its object is to provide an attachment which can be readily placed upon screen doors and windows and which constitutes an exit through which iiies and other like insects can conveniently pass from the interior of the structure to the outside thereof, but through which they cannot enter.
A further object is to provide an attachment which can be readily constructed and placed securely in position upon a screen.
Vith the above and other objects in view the invention consists of a casing having a passage extending longitudinally therethrough and the walls of which converge from the inlet to the outlet end thereof, and formed integral with the casing are securing devices whereby the fabric of the screen can be secured to the casing. f
The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure I is a perspective View of the outside of the window-screen having my improved attachment thereon. Fig. 2 is an inner elevation of said screen. Fig. 3 is an enlarged transverse section through a portion thereof and through the attachment. Fig. et is a bottoni plan view of the attachment, the same being shown in position upon a screen; and Fig. 5 is a detail View of the retaining-strip of the attachment.
Referring to the figures by numerals of reference, l is the frame of a screen, having suitable fabric 2 connected thereto along' three sides thereof, the fourth or upper edge of the fabric being detached from the frame. Secured along this upper edge of the frame is an outlet-casing of novel construction. This casing is formed of a single blank of sheet metal, which is bent to produce an outlet-passage 3, having converging walls, so as to produce an outlet si, which is smaller in width than the inlet 5 of the casing. A iiange 6 is formed integral with the casing, along the bottom thereof, and has depending ears at the ends thereof, while a toothed iiange 8 is arranged along the lower edge of Hange 6 and is adapted to engage thc free edge of the fabric 2. A toothed retaining-strip 9 is arranged between the ears 7 and has lugs l0 at its ends, which are fitted within said ears. The toothed edges of the flange 8 and strip 9 overlap and engage opposite sides of the fabric 2, and it will thus be seen that the free edge of the fabric is thus securely fastened to the casing. Laterallyextending ears l1 extend from the ends of the casing and are secured to the frame l by screws or in any other suitable manner.
The casing is adapted to be secured along the upper edge of the frame 1 with the inlet 5 alining with the lower edge of the upper end of the frame. Then the screen is placed within a window or other suitable place provided therefor, it is so arranged that the casing is on the outer side. As is well known, flies and kindred insects upon alighting upon a screen will crawl upward to the inlet 5 and will pass outward through the passage 3 and the outlet 4. In view of the fact, however, that the outlet is removed from the outer face of the drum l and is located at some distance therefrom it will be understood that the flies will not pass downward therethrough. By employing screens having this attachment upon them a room can be quickly cleared of flies. The attachment can be readily secured to any form of screen door or window and can be constructed and sold at slight cost. In view of its compact form and the position which it occupies upon the screen it does not detract from the appearance of the screen and does not in the least retard the passage of the light.
In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing' any IOO of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall Within the scope of my invention.
Having thus described the invention, what is claimed as new isl. An escape attachment for screens comprising a casing having a longitudinally-extending inlet and outlet at the bottom and top thereof respectively, a toothed flange integral with the casing and extending longitudinally thereunder, and a toothed retaining-strip secured to the casing.
2. An escape attachment for screens comprising a casing having a longitudinally-extending inlet and outlet, a toothed fabric-engaging flange integral therewith, and a longitudinally-extending toothed retainingstrip secured to the casing.
3. An escape attachment for screens having a longitudinally-extending inlet and outlet, a toothed fabric-engaging flange integral with the casing and below the inlet, a toothed retaining-strip extending longitudinally of the casing, and ears integral with the casing and engaging the strip.
4. An escape attachment for screens comprising a casing having a longitudinally-extending inlet and outlet at the bottom and top thereof respectively, integral ears depending therefrom, a longitudinally-extending toothed fabric-engag'ing iiange integral with the casing, and a toothed retaining-strip extending longitudinally between and engaging the ears.
5. The combination with a screen comprising a frame, and a fabric secured thereto; of
`an escape attachment secured to the frame at one side thereof and comprising a casing hav.- ing a longitud inally-extending inlet, and a longitudinally-extending outlet at the bottom and top thereof respectively, ears depending from the ends of the casing, a toothed iange integral with the casing and interposed between the ears, said flange engaging the fabric, a toothed retainingstrip interposed. between and engaging the ears, vsaid strip engaging the FRANKLIN PEARL KNOWLES.
