Application filed S t b 12, 1899. Serial No. 730,256. No model.)

To all rah/07m it may concern.-

Be it known that I, AARON GRAHAM, a citizen of the United States,residing at Ch ristiansburg, in the county of Montgomery and State of Virginia, have invented a new and useful Window-Screen, of which the following is a specification. p

The invention relates to improvements in window-screens.

The object of the present invention is to improve the construction of that class of flyscreens which are provided with fly-escapes and to provide a simple, inexpensive, and efficient screen adapted to be readily applied to the sashes of a window without interfering with the operation thereof and capable of being readily adjusted to form either a closed screen or one with an escape for flies.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective View of a portion of a window, showing a screen applied to the upper or outer sash,suc'h sash being pulled down to arrange the screen at the bottom of the window. Fig. 2 is a vertical sectional view of the same. Fig. 3 is an enlarged detail perspeptive View of a portion of the screen. l

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a rectangular screen suspended from the bottom of the upper sash 2 of a window and consisting of a rectangular frame 4 and a sheet 5 of Wire-netting or other suitable screen materiah The side and bottom bars of the frame 4: are provided at their outer faces with recesses for the reception of the adjacent edges of the screen material, which is clamped therein by strips or cleats 6, and the latter have their outer faces flush with the outer faces of the side and bottom bars of the frame 4.

The top strip or cleat (i has its upper edge flush with the upper ends of the side bars of the screen-frame, and the upper edge of the netting is extended above the upper ends of the side bars, as clearly illustrated in Fig. 2 of the accompanying drawings. The top bar '7 of the frame 4 is reduced in thickness to 0&- set it from the projecting upper edge 8 of the netting for the purpose of providing an opening for the escape offlies. The top cleat 6 is supported between its ends by fastening devices 9, which pass through the said top cleat and have their inner ends embedded in the top bar 7 of the frame 4. The inner face of the top cleat 6 is designed to be white in order to light up the opening or escape 10, and this may be accomplished by painting or otherwise coating the inner face of the cleat or by constructing the latter of white pine or other suitable material. The escape-opening will permit the flies to pass out at the top of the screen, but should it be desired to close the space or opening 10 to prevent the entrance of mosquitos the projecting edge 8 may be bent inward against the outer face of the top bar 7 and the fastening devices 9 will assist in supporting the edge of the screen when bent downward in this manner. The upper edge 8 may be again bent upward when it is desired to provide a fly-escape. The screen is secured to the sash by screws or any other suitable fastening devices,which are arranged as shown in Fig. 2.

. It will be seen that the screen is simple, in-

expensive, strong, and durable, that it is adapted to be readily applied to a window, and that an efficient fly-escape is alforded. It will also be apparent that the projecting edge of the wire-netting at the fly-escape may be bent downward to close the space between the top bar of the frame and the top cleat for excluding mosquitos and other insects.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrh ficing any of the advantages of this invention.

What is claimed is- 1. A screen comprising a frame consisting of side and bottom bars recessed at their outer faces, and atop bar reduced in thickness and ofiset from the recesses of the side and bottom bars,a sheet of screen material arranged with in the said recesses and having its upper edge projecting beyond the upper ends of the side bars and arranged parallel with the outer face of the top bar and separated therefrom by an intervening space or opening and adapted to be bent inward to cover the said space or opening, and cleats secured within the recesses of the side and bottom bars, fitting face and a top cross-piece reduced and offset from the said recesses, a sheet of screen material arranged within the recesses of the side bars and lower cross piece and extending above the lower face of the top cross-piece,and the cleats secured within the recesses of the said side bars and lower cross-piece and having their outer faces flush with the outer faces of such parts, a top oleat located at a point below the upper cross-bar of the frame and at a point below the upper edge of the screen material, whereby the latter may be bent inward over the intervening space between it and the upper cross-piece, substantially as and for the purpose described.

In testimony that I claim the foregoingas my own I have hereto affixed my signature in the presence of two witnesses.

AARON GRAHAM.
