Application filed December 9, 1925. serial No. 74,361.-

This invention relates to screens, asusually constructed to be fitted to windows, doors and like openings in houses to prevent the entrance of flies and like winged insects, and has for its object to provide an escape for any flies, or insects,'that may find their wayv lVhile the drawings illustrate a preferredembodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied, and such other changes in the minor details of construction maybe resorted to within the scope of the invention as. claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached, in which,-

Figure 1 is an elevation view of a fly screen embodying the invention, I

Figure 2 is a detail sectional view on the line 22 of Figure 1 looking in the direction of the arrows, and c s Figure 3 is a detail perspective view of a portion of the screen illustrating more clearly the escape and the parts associated therewith.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters. j Y j The screen comprises the usual frame 1 and wire fabric 2 and, in accordance with the invention, the screen material 2 is slit adjacent an upright bar, as indicated at 3, and a slit 4 extends laterally from the slit 3 and result in providing the escape.

A clip 5 is applied to the corner portion of the flap 10, comprised between the vertical slit 3' and the horizontalslit 4, and serves to reinforce the corner and provide a stop to limit the inward movement of the flap 10.

A plate 6 is disposed upon the inner side of the vertical frame .bar adjacent the slit 3 and is pivoted at its lower end to said bar, as indicated at 7, and this plate constitutes a guard and tapers throughout itslength, b'elng widest at its upper end, which is rounded to clear the portion of thewire fabric'aloove the'horizontal slit or cut 4. YVh'en the flap 1O,formed'by the slits or cuts 3 and4, is

pressedoutwardly at its top edge, as indicatedmost clearly in Figure 2, the guard plate 6 correspondingly moves and closes the spaces wh ch would otherwisebe formed between the vertical edge of the flap and the ad acent vertical bar of the frame.

An operating member 8 is pivotally mounted upon the fastening 7 and-its upper a end engages the upper end of the guard plate 6 and the corner portion of the flap. The member 8 is in the nature; of a lever and is formed from spring. wire and 'ispivoted near its lower end, which is formedinto a loop g) which constitutes a finger piece and which 1s arranged co-engage the inner side of the vertical frame bar frictionally so as to hold the flap in the required-adjusted position. The pivot fastening 7 may consist of any type of fastening and is let'into the vertical bar of the frame, the guard plate 6 and the operating member 8 being mounted thereon. The upper end of the member 8 is bentand extends, through the corner portion ofthe flap 10 and engages the upper end of the guard plate 6, thereby causing the flap and the guard plate to'move in unison.

When the flap is closed, it is in the plane of the wire fabric or other screen material applied to the frame 1, and when the flap is adjusted to provide an opening its top portion is thrown outwardly, as indicated most clearly in Figures 2 and 3, thereby providing a ready escape for flies and other insects alighting upon the inner side of the screen as will be readily understood.

The part receiving the plate 6, operating member 8 and pivot 7 constitutes a support for such parts and may be disposed at any point in the extent of the, fabric 2 so long as it is about in line with the vertical edge of the flap 10.

Having thus described the invention, I claim: 1. A. fly screen having a portion partly out therefrom to provide a flap, and means for moving an edge portion of the flap to provide an escape'opening. Y

2. In fly screen, a flap part1 out there'- from by intersecting angular 7 dis osed slits, means for moving the flap mwar 1y to close the opening, which would otherwise be formed when the flap is adjusted to provide the escape.

3. In a fly screen, aflap comprised be tween intersecting vertical and horizontal cuts means for moving the top portion of the flap to provide an escape opening,-- and a guard for closing theopening at the vertical edge of the flap when the latter is adjusted to provide the escape opening.

4i. A fly sor'een comprising a frame, and wire fabric covering the frame and having intersecting vertical and horizontal slits forming a flap, means for adjusting the upper portion of the flap outwardly to provide an escape opening and a clip a-pplied'to the Corner portionof the flap to reinforce the same and provide a stop. v v

5. A fly s'c'i'e'en comprising a frame and wire fabric covering the frame, and having intersecting vertical and horizontal slits formin aflap, a gluard'plate pivoted at its lower end to the upright of thefraine ad jacent-the vertical edge of the flap, and connecti lg means between the upper end of the pivoted guard plateand a corner portion of the flap, whereby both the flap and guard plate move together. 1

6. screen comprising a frame 'and wire fabric covering: the f-r'ain'e and having intersecting vertical horizontal slits forming a flap, a guard plate pii' oted at its lower endft'o the upright ofthe frame adjacent the flap, and an operating member pivoted near its lower end to the upright of the frame and having its upper end engaging the flap and guard plate and forming connecting means therebetween.

7. A fly screen comprising a frame, wire fabric covering the frame and having intersecting vertical and horizontal slits forming a flap, a clip applied to the corner portion of the flap to reinforce the same and provide a stop, a guard plate pivoted at its lower end to the upright of the frame adjacent the vertical edge of the flap, and increasing in Width from bottonitotop and a spring operating member pivoted near its lower end to the saidupright of the frame, and having its upper portion passing through the corner portion of the flap and engaging the upper end of the pivoted guard plate-and formingconn'ecting means between the flap and guard.

8. Means for use in connection with a wire fabric, as employed for excluding flies and other winged insects, after the fabric has been cut to'proVid'e 'a' fla'p, the same c0ns'isting'of a member adapted-to be pivotally attached to a sul'aport, adjacent any desired portion of the screen and engaged with the flap to move the same, a guard plate for closing the side opening and movable with the flapand member, and a pivot support for the member and guard plate;

In testimony whereof I afiix my signature.-
