SCREEN.

Application filed February 11, 1928. Serial No. 253,742.

This invention relates to screens and it is an object of the invention to provide a device of this kind which may be termed an all year round screen, thus obviating the necessity of applying and removing the screen at the time of seasonal changes as is now the general practice.

It is also an object of the invention to provide a screen of this kind which comprises two difiering meshes, one mesh being of the conventional insect or fly gauge while the other mesh is of a weather or ventilating type, thus permitting the screento be employed as a ventilating medium. when desired in exclusion to the fly or insect mesh.

' An additional object of the invention is to associate with a device of this kind means for bridging the space between a window sash and the applied screen to provide an effective medium to prevent draft or other matter passing through an open window when the weather or ventilating cloth only is to be used, as in cold or inclement weather.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved screen whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein Figure 1 is an elevational view of a screen constructed in accordance withan embodimen of my invention, a portion of the closure plate being broken away;

Figure 2 is a fragmentary sectional view illustrating the operative relation of the screen when in applied position in connec tion with an associated window sash.

My improved screen, as herein disclosed, comprises a frame F constructed in any desired manner and of such dimensions as may be preferred and which has disposed across its lower portion at a predetermined point above the lower member 1 of the frame 'a cross member 2 and field defined by the members 1 and 2 and the intermediate portions of the side members 3 of the frame is closed by a cloth 4 of a fine mesh, such as is employed for weather or ventilating purposes.

The field or opening defined by the top member 5, member 2 and the intermediate side members 3 of the frame is closed by a conventional fly or insect cloth 6.

Disposed entirely along the member 2 and thereby extending substantially entirely across the completed screen is an outstanding plate 7 of spring copper or other preferred material possessing the requisite inherent resiliency. This plate extends beyond the inner face of the screen when applied and is of a length to bridge or close the space between the applied screen and the lower rail 8 of a window sash and more especially when said Window sash is partially raised for the purpose of ventilation as in cold or inclement weather. The inherent resiliency of the plate 7 is'such as to normally maintain the same at the limit of its upward or outward movement but will readily yield or flex to permit the desired raising and lowering of the window sash and also to compensate for variance in spacings between the applied screen and associated sash.

To facilitate the raising and lowering of a sash with a minimum of resistance being offered by the plate 7 I find it advantageous to downwardly curve or round the outer marginal portion of said plate 7, as indicated at 9.

With the use of my improved screen the same can be maintained in applied position all the year round. In warm weather, or under other conditions justifying the same, the window sash may be raised as high as desired to get the benefit of the air passing through both the upper and lower cloths but in the winter or inclement weather when it-is only desired to raise the sash sufficient to obtain effective ventilation, said sash will not be lifted to bring the bottom rail 8 above the plate 7 thus assuring an effective closure against any draft entering through the upper or insect mesh down under the partially open window and also to efi'ectively close against admission within the room of rain, snow, dust, or other matter.

From the foregoing description it is thought to be obvious that a screen constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled. and operated, and it will also be obvious that my invention is susceptible of some change and modification without de- 1. As a new article of manufacture, a Window screen comprising a frame, screen cloths disposed over the frame of differing meshes, one of said cloths constituting a ventilating cloth and the other constituting a fly or insect cloth, and a resilient plate extending across the screen between the ventilating cloth and the fly or insect cloth for contact with an adjacent Window'sash when the screen is in applied position and particularly when the sash is partially raised for purposes of ventilation.

2. In a window screen of the character described, a frame, a bar extending transversely of and within the frame'dividing the frame into two parts constituting upper and lower sections, 'ascreen fabric in said upper section,

a fabric in said lower section of closer weave than the screen fabr1c,'and an elongated resilient plate secured along one longitudinal edge to said bar and extending substantially the entire width of the frame, said plate being designed to project across a space between the frame and an adjacent window sash to permit air to pass through the frame only through the lower section.

3. In a window screen of the character described, a frame, a bar extending transversely of and within the frame dividing the frame into two parts constituting upper and lower sections, a screen fabric in said upper section, a fabric in said lower section of closer weave than the screen fabric, and an elongated resilient plate secured along one longitudinal edge of said bar and extending substantially the entire width of the frame, said plate being designed to project across a space between the frame and an adjacent window sash to permit air to pass through the frame only through the lower section, said plate being transversely arcuate and having its free edge clirected downwardly and further rolled under to provide a rounded window sash contacting portion.

In testimony whereof I hereunto aflix'my signature.
