FLY-ESCAPE Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed August 23, 1907. Serial No. 389,828.

To all whom it may concern:

Bc it known that I, ANDREW W. SALOKAR, a citizen of the United States, residing at New Brighton, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Fly-Escapes; and l 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.

My invention has for its object to provide an improved device or attachment for window screens, which is adapted to permit fiies to readily escape from a room or other inclosure, but which will prevent them from entering through the said device.

To the above ends, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

The present invention is in the nature of an improvement on the device disclosed and claimed in my prior patent No. 831,380, of date September 18th, 1906, entitled Fly escape.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings; Figure l is an elevation looking at the inside of a screen and showing my improved ily escape device applied thereto, with some parts broken away. Fig. 2 is a vertical section taken on the line ai? x2 of Fig. l. Fig. 3 is a sectional view taken on the same line as Fig. 2, but showing the parts on a larger scale and with some parts broken away; and Fig. 4 is an elevation looking at the outside of the screen, showing the fly escape device or attachment removed therefrom, and with some parts broken away.

The numeral 1 indicates the frame, and the numeral 2 the reticulate wire portion of an ordinary window screen. For the application of the improved fly escape device or attachment, the reticulate wire sheet 2 is cut away or slit and turned downward, as shown at 2a, and in line with this opening, a rectangular frame or casing 3 is secured to the outer side of the frame 1 and screen 2. As shown, the casin 3 is provided with an outwardly eXtende bottom plate 3 that rests upon a supporting plate 4 that is secured to the screen 2 by a short nutted bolt 5 and a cooperating clamping bar 6. The top of the casing 3 is provided with a depending outer {iange 3", and with a depending inner flange 3. To the flange 3b is bolted, or otherwise rigidly secured, a toothed guide bar or comb 7; and to the iiange 3C is secured the upturned inner edge of an outwardly inclined guard plate 8, the projecting edge of which terminates approximately at the depending end of the teeth of the uide comb 7. A series of laterally spaced light catch rods 9 work freely between the teeth of the guide comb 7 and are loosely pivoted on a supporting rod 10, which rod extends longitudinally through the casing 3 and is secured to the ends thereof. The free outwardly projecting ends of these catch rods 9 are held by gravity in a position close to the bottom plate 3a of the casing 3, and the said rods are so closely spaced that a fly cannot pass between the same.

The numeral 11 indicates extension blocks which, as shown, are secured to the flanged ends of the casing 3.

With the device above described, flies at the interior of the building will pass up the screen 2 until they come to the opening formed within the casing 3 below the guard plate 8, and they will then find a free outward passage until they come into engagement with the free ends of the catch rods 9. Very slight pressure against the free ends of these catch rods will raise the same so that the ies will find very easy outward passage under the said rods. It is, however, evident that the flies' cannot pass inward because the rods cannot be raised from the exterior of the device by pressure against the rods.

In actual practice, the device above described has been found highly eiiicient for the purposes had in view. It is of small cost, and may be easily applied to screens as found in general use. The device above described may, of course, be applied to door screens, as well as to window screens. It may even be a plied to a window sash or to an ordinary oor.

What I claim is In a ily escape device, the combination with a rectangular frame or casing having a bottom plate and an opening through which the flies may pass, of a detachable guide comb secured to and depending from the upper outer portion of said frame or asin a uard lat underl in said uide combigr a rgnultiplicitlf of olobel?`y posioned laterally spaced gravity held catch rods, the inner and upper ends of which are independently pivoted Within the said frame or casing, and the free ends of which are Supl ported by said guard plate and overle and closely engage the bottom plate of said frame or easing, substantially as and for the purposes sot forth.

In testimon f whereof I aliix my signature in presence of3 two Witnesses.
