WINDOW SCREEN.

Application filed April 12, 1927. Serial No. 183,94 0.

This invention relates to a novel window screen, the object of the invention being to provide a simple and cheap combmation screen which will provide for proper ventilation under all conditions and at the same time protect against strong winds or extreme cold. V

VVit-h these objects in view, the invention includes a window screen having combined therewith a smaller ventilating screen of finer mesh removable from the window screen, so as to permit the larger mesh portion of the Window screen to be closed by the Window, leaving the portion covered by'the finer mesh ventilating screen open, theventilating screen preferably carrying a closure which may be used to wholly or partially close the ventilating screen when desired.

In the accompanying drawings forming a part of this specification, the invention is illustrated in its preferred form. and this construction will now bediscussed in detailand the features forming the invention then specifically pointed out in the claims.

In the drawings,--

Figure 1 is a face View of the window screen embodying all the features of the invention, and

Figure 2 is a perspective view of a portion of the ventilating screen.

Referring to the drawings, A is the window screen frame anda the comparatively open mesh wire screen therein, this window screen being the full depth for covering the whole or part of the window, as usual. Within frame A is removably mounted a ventilating screen frame B carrying the wire screen I) of finer mesh than the screen a, this ventilating screen being shown as mounted to cover the entire width of a part of the window screen at its lower end and removably mounted in the frame A, simply being set within the frame and held in place by slides 1 mounted on frame B and entering holes in frame A. It will be understood, however, that this venti lating screen may be mounted at the top of the window screen if it be desired to ventilate through the upper part of the window.

This ventilating screen may be used alone with the window screen, but preferably the ventilating screen carries a swinging plate C of glass, but which may be of any other suitable material, preferably hinged on the bottom rail of frame B by hinges 2, as shown, so that the screen 5 may be wholly or partially covered by the plate (land the ventilating air from screen 6 directed upward into the room, as desired.

With my improved window screen, the window screens may be left in the windows throughout the year, being mounted so as to permit the window to slide up and down inside the screen, as usual, and the smallventilating screen be removed for free flow of air through the close-mesh screen a during the warm weather. In colder weather, the ventilating screen will be put in place in the window screen and. its close mesh screenb will permit theroom to be ventilated with a less free flow of air, while the open mesh screen a is closed by the window. The flow of air through the close mesh screen 6, also, can be prevented by closing the ventilating screen by plate C, or the air admitted through the screen 6 controlled as desired by the position of plate C.

It will be understood that the invention is 1 not limited to the specific construction illusw extending vertically over only a portion of U the window screen at one end of the window.

2. o The combination with a window screen, of a ventilating screen frame extending over the entire width of only a portion of the window screen at the lower end of the win dow and having screening material of finer mesh than .the window screen,,said ventilating screen frame being removablymounted in the window screen frame.
