WINDOW VENTILATOR Filed Nov. 21, 1951 I a I I Hi i I v nuculo'a lfll airbairiz Patented Dec. 22, 1953 V UNITED STATES TENT OFFICE 1 Claim. 1

This invention relates to a window ventilator which is so constructed that it may be positioned exteriorly of a window frame and the window opened, thereby permitting air to enter the room through the open window, the Opening of the window being guarded by the ventilator to the end that it is possible to provide effective ventilation without sacrificing privacy.

Another important object of the invention is to provide a device of this character which will permit of circulation of air downwardly through the top of the ventilator, and upwardly, through the bottom thereof, and at the same time provide a ventilator wherein rain will be excluded from entering the open window.

Still another object of the invention is to provide a ventilator of this character which may be readily and easily folded into a small and compact article, and one which may be readily and easily removed and replaced as desired.

With the foregoing and other objects in View which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing,

Figure 1 is a perspective View illustrating a window ventilator constructed in accordance with the invention, as mounted on a window frame.

Fig. 2 is a vertical sectional view through the ventilator.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2. I

Fig. 4 is an enlarged fragmental interior view of one corner of the ventilator.

Referring to the drawing in detail, the ventilator comprises a body portion including end sections 5 and a front section 6, the end sections being provided with horizontal bars 1 that are secured thereto at points intermediate the upper and lower ends thereof.

The reference character 8 indicates a horizontal bar which is secured to the front section 6 at a point substantially intermediate the upper and lower ends thereof, the ends of the horizontal bar 8 lying adjacent to the outer ends of the horizontal bars 1, the adjacent ends of the bars I and 8 being provided with hinges 9 whereby theend sections may be folded over the front section, when it is desired to store the ventilator.

As shown, the front section 6 is wider than the end sections 5, to the end that the lower edge of the front section 6 extends a substantial distance below the lower ends of the end sections 5,

providing the extension it which is disposed below the window sill, which in the present showing is indicated by the reference character H.

As shown, the front edges of the end sections 5 are inclined inwardly towards the lower ends thereof, so that the front section 5 is caused to be inclined inwardly towards the lower end of the ventilator, providing an entrance opening at the bottom of the ventilator which is substantially smaller than the opening at the top of the ventilator.

Hooks I2 extend inwardly from the free ends of the horizontal bars I, which hooksare positioned within the screw eyes it that are secured to the window frame in a position to properly locate the ventilator at the bottom of a window.

From the foregoing it will be seen that due to the construction shown and described, I have provided a ventilator to be used with open windows, to the end that a room may be properly ventilated without sacrificing privacy of the 5 room.

It will also be seen that due to this construction, I have provided a ventilator which when used with the usual attic circulating fan, will permit fresh air to be drawn into a window, and since both the bottom and top of the ventilator are open, it will be obvious that air will be drawn in through the bottom of the ventilator as well as through the top of the ventilator, creating a suction and at the same time providing a bottomless ventilator so that the elements may not collect in the ventilator to the discomfort of the persons in the room.

Having thus described the invention, what claimed is:

A window ventilator for positioning adjacent to the outer sides of windows having sills, comprising a body having an open top and bottom, end sections and a front section, means for pivotally connecting the end sections to said front section, the upper and lower edges of each'end section being parallel, the lower edge of said front section extending a substantial distance below the lower ends of said end sections in spaced relation with the sill providing a vertical passageway through the bottom and top of said ventilator, and means for removably securing the ventilator adjacent to said open window.
