JOHN A. GEE, OF CRIPPLE CREEK, COLORADO.

Specification of Letters Patent.

Patented March 5, 1907- Application filed September 13, 1906. Serial No. 334,529.

To all whom it may concern:

Be it known that I, J OHN A. GEE, a citizen of the United States, residing at Cripple Creek, in the county of Teller and State of Colorado, have invented certain new and useful Improvements in Fly-Escapements for Window and Door Screens; and I do 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 improvements in fly-escapements for'window and door screens.

The object of the invention is to provide an attachment for window and door screens through which flies and other insects may readily find an exit, but through which insects will not be apt to enter.

A further object is to provide an attachment of this character which will be simple and inexpensive in construction, efficient in operation, and which may be readily attached to various forms of window or door screens and be invisible from the exterior thereof.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and ar rangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an outer side view of the upper portion of a window-screen, showing the application of the invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view through a portion of the upper bar of the screen-frame and the escapement, and Fig. 4 is a detail perspective view of the escapement removed from the screen.

Referring more particularly to the drawings, 1 denotes the escapement, which is preferably constructed of a single piece of sheet metal bent to form an outwardlycurved substantially triangular or upwardlytapering body portion 2, the upper or outer end of which is closed, as shown at 3. In the outer curved side of the body portion 2, adj acent to the upper end thereof, is formed an exit-opening 4. The lower edge of the bulged or outwardly-extending portion is notched or cut away nearly up to the opening 4, as shown at 5, to permit of the entrance of light to what would otherwise be a dark passage through which the flies would pass but slowly, if at all.

Formed integral with the inner edges of the lower portion of the escapement are laterally-projecting flanges 6, which are in a plane even with the inner edges of the body portion 2 and extend up substantially even with the opening 4 and in which are formed openings 7 to receive tacks or other fastening devices, by means of which the escapement is secured to the screen-frame.

As will be noted by reference to Figs. 1 and 2, the escapement is of the same length as the width of the screen-frame bar S, and by thus constructing the article it is rendered invisible from the exterior of the screen or door, thereby obviating an objection common to such attachments.

In arranging the device on a screen the same is inserted between the outer edge of the netting and the adjacent side of the screen-frame, with the inner or open side of the body portion of the escapement engaging the frame of the screen, said body portion 6 thus forming a passage through the open inner end of which flies or other insects crawling on the inside of the screen may enter and pass out through the exit 4, which opens beyond the edges of the netting and outside the $010611, thus allowing the insects to pass out of the room. By providing the opening 5 in the outer side of the body portion light is admitted to the passage formed by the body portion of the escapement, so that the flies or other insects will not be deterred from entering and passing through the escapement.

By providing an esoapement such as herein shown and described and arranging the same on the screen a ready exit is provided through which insects may pass out, but will not readily enter.

The device may be attached to any form of screen adjacent to the outer edge of the same and is preferably, though not necessari ly, secured to the upper cross-bar or frame of the screen, because of the well-known propensity of flies or other insects to crawl upwardly when seeking a means of escape.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined by the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, an attachment for screen-doors comprising an upwardly-tapering, bulged body portion having its upper end closed and the lower end open and the sides rovided with laterally-extending perforate flanges, said flanges being in a plane even with the inner edges of the body and the body being provided with an opening near its closed end and having its lower edges cut away nearly up to said opening.

2. In combination with a screen-door, a fly-escapement secured to the top bar thereof, said escapement comprising a bulged body portion having its upper end closed and its lower end open, and the sides provided with perforated flanges which extend laterally in a plane even with the inner edges of the body and are secured to said frame, the body being provided with an opening near its closed end and the lower edge being cut away nearly up to said opening, and the screen material covering the cut-away portion of said body, whereby the insect in passing through the attachment will be compelled to pass from the opening in the top of the body down between t e body and the frame.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN A. GEE.
