VENTILATING SCREEN FOR vWINDOWS.

SPECIFICATION forming part of Letters Patent No. 271,146, dated January 23, 1883, Application filed August 17, 1882. (No model.)

To all whom it may concern Be it known that I, SARAH B. S'JEARNS, of Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Ventilating-Screens for Windows, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of referen'ceindicate corresponding parts in both the figures.

Figure 1 isa perspective view of my improve ment. Fig. 2 is a sectional side elevation of the same.

The object of this invention is to secure a thorough ventilation of school-rooms and other rooms without exposing the occupants of the rooms to currents of air.

The invention consists in a ventilating-screen for windows constructed with aframe provided with eyes at its corners and at the middle parts of its outer and end bars, and hinged to a window-casing by screws passing through the eyes at its inner corners. The frame is covered with cloth having upright triangular ends, and provided with eyelets along its outer edge and its inclined end edges, to receive cords attached to the screen-frame and passing through the eyes of the eye-screws attached to the window-casing, so that the screen can be readily adjusted.

The ventilating-screen is provided with a gauze-covered frame hinged to the windowcasing by the same screws that hinge the said ventilating-screen to the said casing, so that the said screen can be turned up to exclude mosquitoes and flies, while air is freely admitted and distributed through the upper part of a room, as will be hereinafter fully described.

A represents a window-casin g, B the upper sash, and O the lower sash.

D is a three-sided frame, made of a metal rod or other suitable material, and of such a length as to fit into the space between the sides of the casing A, where it is secured in place and hinged to the casing by screws E passing through eyes or holes F in the inner corners of the frame D, and screwed into the said casing or into a metal support attached to the casing at such a. distance from its top that when the frame D is swung upward its outer bar will reach to the top of the casing.

If desired, the frameD can be hinged to the inner side of the top bar of the upper sash, B, by eye or hook screws or other suitable means, so that the screen can be raised by and with the said upper sash to allow the lower sash to be fully raised, the said hinging bearings being so formed as to hold the cross-bar Q.

In theouter corners of the frame D, in the center of the outer bar of the said frame, and in the centers of its end bars, are formed eyes or holes, marked respectively G H I, to receive theadjusting-cords J K.

The screen-cover L is made of cloth, with inclined ends, and of a length at the outer edge equal to the length of the frame D, andat its upper edge equal to the length of theframe plus twice its width, so that when the frame D is in a horizontal position and the ends of the cover L are turned up vertically the said ends will have the form of right-angled isosceles triangles. The cover L is secured to the eyes F G H of the frame D, and the upper corners of its ends are secured to the hook-screws M, attached to the casing near the eyescrews Vi, screwed into the casingA, to receive and serve as guides to the cords J K.

Thelower edge ofthe cover L is kept straight, and is held against the window-sash, so as to prevent air from entering the room between the said cover and sash, by a light bar, Q, of wood or other suitable material, inserted in a hem in the edge of the cover, with its ends in sockets in the metal supports R, to which the inner corners of the frame D are hinged.

The cord J is attached at its center to the eye H, passes through the eyes G, through eyelets N in the outer and end edges of the cover L, and through the eyes of the eye-screws M. The cord K is secured at its center to the eye H, and passes through the eyes I and the eyes of the eye-screws M. From the eyes of the eyescrews M the cords J K pass down along the side casings, A, into such a position that they can be conveniently reached and operated to V adjust the screen 1) L, and where they are secured to eyescrews, belaying-cleats, or other suitable fastenings. With this construction, when the screen I) L is in a horizontal position and the upper sash, B, is lowered till its top bar is at the inner edge of the said screen D L, the air entering the room will be made to pass into and be spread through the upper part ICC of the said room, so as to be warmed slightly as it gradually settles into the lower part of the room, so that the occupants of the room will not be exposed to the direct action of currents of cold air. 1

Should the direction of the wind be such as to force-too strong a current of air into the room, the screen D L can be adjusted at a greater or less angle with the window, so as to direct the current of air against the ceiling, along which it will spread before settling into the lower part of the room.

With this improvement a thorough ventilation of a room can be had at all times without exposing the occupants of the room to currents of cold air.

O is a frame covered with gauze or mosquitonetting P, so as to exclude mosquitoes and flies, while allowing air to pass through freely. The screen 0 P is hinged at its inner corners to the casing Aby the screws E, that hinge the screen DL to the said casing. When the screen 0 P is not required for use it is turned down upon the screen D L, so as to be entirely out of the way, and to be raised and lowered by and with the screen D L as the said screen is raised and lowered. When the screen 0 P is required for use it is turned upinto the upper part of the casing A, as shown in Fig. 1, and allowed-to remain there, being unaffected by the movements of the screen D L.

Patent- 1. A ventilating-screen for windows, constructed substantially as herein shown and described, and consisting of the frame D, having eyes F Gr H I, thecover L, attached to the said frame, and the cords J K for adjusting the screen, as set forth.

2. In a ventilatingscreen for windows, the combination, with the casing A, of the frame D, having eyes F G H I, the hinging-screws E, the cover L, having eyelets N, the cords J K, and the eye-screws M, substantially as herein shown and described, whereby the entering current of air is guided into and distributed through the upperpartot'the room, as set forth.

3. In a ventilating-screen for windows, the combination, with the casing A, the screen D L J K, and the hinging-screws E, of the gauzecovered frame 0 P, substantially as herein shown and described, whereby mosquitoes and flies can be excluded, while admitting the air and guiding it into the upper part of the room, as set forth.
