the window stool when the easement is partlyopened, make it difficult to use the orthodox hinged window screen. One of the special disadvantages of the hinged screen is due to the fact that said screen must open inwardly and in so doing the upper part of the screen frame contacts the drapes of the window and disturbs their hangings and sometimes tears said drapes close to the head of the window. Where Venetian blinds are used either on sash or casement windows, there is no room to place a fly screen between the blind and the sash and frequently the width of the blind laths is such as to preclude the possibility of hinging a fly screen on the inside of the window frame. It is with the object of avoiding these defects that the contemplated invention is designed.
The invention consists of a foraminous screen having substantially rigid frame members on two opposing marginal edges and flexible non-metallic bindings on the remaining marginal edges, as will be more fully described in the following specification and shown in the accompanying drawing, in which- Fig. 1 is an elevational view of the screen as viewed from the interior of the room.
Fig. 2 is a detail sectional view of the upper border of the screen.
Fig. 3 is a detail sectional view of the lower border of the screen.
Fig. 4 is a detail sectional view of the side border of the screen.
Fig. 5 is a detail sectional view showing the preferred form of fastening of the screen to the window frame.
In the drawing like characters of reference indicate corresponding parts in each figure.
The numeral l indicates a window frame having stiles 2, a head 3, a casement sash 4 and a stool 5. The casement sash is presumably provided with a casement fastener 6 and a casement stay I. Fitted to the inner face of the stiles 2 and the head 3 are brackets 8, which preferably support the stem portion 9 of a so-called Lift the Dot fastener l0. Detachably connected to the stem portions 9 by clip portions ll of the fastener I is a wire screen l2 which is the subject matter of the invention.
The screen I2 is provided on its side edges with borders M, on its upper edge with a border l and on its lower edge with a border 16. These borders are formed with a strip or web of flexible textile material H or any other suitable material such as rubber or the like. Where textile webbing is used it is folded upon itself and upon the edge of the screen material and is stitched as at l8 in any appropriate manner as shown in Figures 2, 3 and 4. The upper border [5 and the lower border l6 are each provided with a stiffening rod 19 which serves to prevent the edge to which it is applied from bending to any serious extent. The webbing ll of the lower border 16 is preferably of greater width than that on the sides and upper edge of the screen l2, so that the stiffening rod [9 may lie above the level of the bar 20 of the casement stay I.
The screen as shown in Figure 1 is clipped along its top border l5 and both side borders I4, the webbing [1 serving to intimately contact with the window frame members.
When it is necessary to open the easement sash 4 the lower corner of the screen adjacent the easement fastener 6 is drawn inwardly as shown, causing the fasteners H) to become disconnected on that side of the window and allowing the lower side portion of the screen to be folded back and afford access to the easement fastener 6, and to the stay I. When the sash is locked in adjusted position the corner of the screen is allowed to drop and the clip fasteners l0 are pressed together to complete the closure. If the bar 20 of the stay 1 projects inwardly beyond the plane of the screen the strip I! of the border will drape over said bar and leave only a small gap immediately below said bar.
It will be obvious that the side borders of the screen may be stiffened with the rods l9 and the top and bottom borders left as flexible members as an alternative equivalent structure.
It is also contemplated that the bottom border may be provided with a fringe to extend from the height of the bar 20 of the stay I to the surface of the stool 5.
What I claim as my invention is:
1. A window screen comprising a sheet of wire mesh, a strip of textile fabric folded along a medial line forming a border for' each of the marginal edges of the wire mesh, said wire mesh extending into the fold of each strip and tenninating'at a line remote from the fold, the outer folded portions of said strip lying in intimate contact with each other.
2. A window screen comprising a sheet of Wire mesh, a strip of textile fabric folded along a medial line forming a border for each of the marginal edges of the wire mesh, said wire mesh extending into the fold of each strip and terminating at a line remote from the fold, the outer folded portions of said strip lying in intimate contact with each other, two opposing marginal edges of said wire mesh being provided with stiffening rods intermediate the width of the folged textile fabric strip and remote from the fa LAWRENCE BRADSHAW.
