WINDOW VENTILATOR Filed Now 17, 1928 )VENTOR 1 BY ATTORNEY Patented Nov. 5, 1929 EUGENE J. HEY, OF NEW YORK, N. Y.

wmnow man-Aron Application filed November 17, 1928. Serial No. 320,095.

The present invention relates to window ventilators of the type which is adapted for cooperation with the ordinary vertically sliding lower sash of customary window construction.

One of the objects of the invention is to provide a ventilator of the type mentioned which may be quickly and readily applied to any form of slidlng sash window and which not onl deflects the air passing into the building t rough the ventilator but also screens the same, so as to prevent dirt, dust and insects from entering the building.

I Another object of the invention is to pro- 16 vide a simply constructed ventilator, formed of a relatively few number of parts which can be quickly and readily assembled or disassembled.

With these and other objects in view, which '20 will more fully appear as the nature of the invention is better understood, the same con- .sists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illus- 2 trated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several .parts and details of construction within the scope of the appended claims, without departin from the spirit or sacrificing any of the a vantages of the invention.

One of the many possible embodiments of the invention is lllustrated in the accompanying drawings, in which:

35. Figure 1 is a rspective view showing the improved ventilator positioned on a window; Fig. 2 is a section taken in the plane 2-2 of Fig. 1, on a larger scale; and Fig. 3 is a section taken on hne 3-3 of Fig. 2.

Referring now to the drawin ,the numera]. 10 indicates the lower sash of a window, slidable in 'a window casing 11. The ventilator, which is to be secured to the said 'ca consists of two' substantially triangu ar, preferably, sheet-metal plates or brackets 12, attached by screws 13, or the like, to the vertical members ofthe casing immediately above the sill 14 thereof. Each of these plates is in the. form of aright- 5 angled triangle, although this is not essential.

These plates are so attached to the casing that they permit of free sliding movement of window sashes, their vertical edges 14: being for this purpose spaced from the lower sash. The plates roject into the room, that is to say outwar 1y of the window frame and their slanting edge portions 15 are each provided with two spaced flanges 16, forming a channel. Into these channels,.which are in alignment, may be slid a deflecting frame 17 of wood, or the like, extending across the entire width of the window. opening and holding one or more glass panes 18.

The upper. rail 19 of this frame projects by hinges 20, a screen frame 21, which extends horizontally from the inclined edge portions of the plates 12 to the lower window sash, it being adapted to rest upon inwardlybent horizontal flanges 22, formed upon the 7 plates 12. The screen frame is covered with a fine-meshed wire fabric 23, or the like, the said fabric being held upon the frame in any suitable manner, for'instance by means of molding strips 24. That rail of the screen frame 21 which is disposed adjacent the window sash carries a resilient strip 25.0f felt or rubber, the said strip being adapted ,to abut against the lower rail of the window sash when the latter is raised to permit ven- 8 tilation of the room. To the screen frame is attached a handle or knob 26, by means of which it may be raised or lowered as required. To the lower rail of the deflecting frame 17 is attached a resilient strip 27 of felt or rubber for contact with the sill of the window casing. The strips 25 and 27 serve, obviously, to make air-tight closures.

The operation of this device is as follows:

When the device is in position on a window casing, as shown in Flgs. 1 to 3, inclusive, of the drawings, the lower window sash is. raised until the lower rail thereof is in abutment with the strip 25 on the screen frame 21. Air entering-through the fabric 23 passes i into the room through the window aperture and is directed upwardly, thus avoiding direct draft. The fabric screens the air, permitting thorough ventilation without the accompanying annoyance of dust and insects.

above the flanges 16 and has attached to it, 5

If necessary, the screen frame may be shifted around its hinges 20 unto the deflecting frame. More air will thus enter the room, but dust, dirt and insects will not be excluded therefrom.

What I claim is:

1. In combination with a window casing and a vertically slidablesash therein, of a pair of triangular plates secured to the vertical members of said casing immediately above the sill portion thereof so as to pro'ect into the room, a pair of channels forme in said plates in alignment with one another,

a deflecting frame slidable in said channels I and resting-upon said sill, the upper rail of said frame being spaced from said sash, horizontal flanges formed upon said plates below the upper rail of said frame, and a screen frame hinged to said upper rail and adapted to rest on the flanges of said plates, the free longitudinal edge of said screen frame abutting against the lower rail of said sashwhen the latter is raised to permit access of air.

into the room through said screen frame.

2. The combination according to claim 1,

comprising a resilient strip on said screen frame to contact with thelower rail of said sash when said screen frame rests upon said flanges.

3. The combination according to claim 1, comprising a resilient strip on the lower rail oflsaid deflecting frame in contactwith said sil Signed at the city of New York, in the county of New York, and State of New York, this 10th day of November, A. D. 1928.
