Application June 28, 1935, Serial No. 28,927

2 Claims. (01. 156-37) The present invention relates to window and door screens used for the exclusion of flies and other insects and prime object of the invention is to take advantage of the well-known aptitude of such insects when lying upon a vertical surface to crawl upwardly and provide for an exit from, but no entrance to the room or the like.

Another important object of the invention resides in the provision of a screen of this nature which is simple in its construction, inexpensive to manufacture, thoroughly efiicient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is an outside elevation of a screen embodying the features of my invention.

Figure 2 is an inside elevation thereof.

Figure 3 is a horizontal section taken substantially on the line 3-3 of Figure 1.

Figure 4 is a vertical section taken substantially on the line 4-4 of Figure 1.

Figure 5 is a perspective view of one of the cross bars.

Figure 6 is a fragmentary elevation showing one of the outer frames removed.

Referring to the drawings in detail it will be seen that I utilize three rectangular frames, namely, the inner frame 5, the outer frame 6, and the intermediate frame I. A bar 1 extends across the upper portion of the frame 5, a bar 1a extends across the central portion of the frame I and a bar lb extends across the lower portion of the frame 6. These bars are identical in construction and all are provided in their outer edges with a plurality of notches 8.

A foraminous panel 9 is fixed to the rail of the frame 5 and to the side rail thereof and extends downwardly a slight distance below the bar I. A foraminous panel l is fixed at its upper edge to the outer side of the bar I and to the inner side of the bar 1a and between the side rails of the frames and l and extend slightly down below the bar 1a. A panel of foraminous material H is fixed to the outer portion of the bar la and extends downwardly and has its side edges fixed between the frames 1' and 6 and is fixed to the outer side of the bar lb and extends slightly down therebelow.

A foraminous panel 12 is fixed to the outer edge of the frame I and the outer edge of the bottom rail of the frame 6 and the sides thereof.

From the above detailed description, it will be seen that a fiy or the like, landing on the inner side of my screen by its natural tendency will crawl on the panels II], II or [2 and pass out through one of the notches 8.

It is thought that the construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is:

1. A screen of the class described comprising three frames superimposed and fixed together, one of the frames being an inner frame, another of the frames being an outer frame, and the remaining frame being an intermediate frame, a foraminous panel fixed to the inner frame across the upper portion thereof, a second foraminous panel fixed between the inner frame and the intermediate frame in overlapping relationship to the first mentioned panel, a third panel fixed between the intermediate frame and the outer frame in overlapping relationship to the second panel, and a fourth foraminous panel fixed to the outer frame in overlapping relationship to the third panel and at the bottom end of the outer frame, and slotted bars extending across the several frames at the upper ends of the second, third and fourth panels.

2. A screen of the class described including frames superimposed and fixed together, one of the frames being an inner frame, a foraminous panel fixed to the inner frame across the upper portion thereof, and other foraminous panels severally and progressively fixed to the other frames in overlapping relation, and slotted bars extending across the several frames at the upper ends of said other panels.
