VENTILATOR.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed November 3, 1913. Serial No. 798,924.

I '0 all whom it may concern:

Be it known that I, CHARLES SAUNDERS, a citizen of the United States, residing at Saginaw, 'in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to ventilators and more particularly to ventilators adapted to be secured to the top and exterior of a win dow for ventilating a room, hall or the like.

The object of my invention is to provide a device so constructed as to prevent any sudden cold drafts or sudden air currents in the window of a room.

A further object of the invention is to provide a device constructed so as to prevent dust, rain, snow, flies and the like from entering the room, no matter from which direction the wind may be blowing.

A still further object is to provide a ventilator that is simple and comparatively inexpensive in construction, thoroughly eflieient and practical for the purpose intended.

WVith the above and other objects in view, my invention consists in certain new and novel features of construction, arrangement and combination of parts, and the equivalents thereof, as will be hereinafter more fully described and finally pointed out in the appended claims.

Referring to the drawings forming a part of this specification wherein like characters of reference denote similar parts throughout the several views:

Figure 1 is a view in perspective showing my improved ventilator in place over a window. Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1. Fig. 3 is a longitudinal section of the hood taken on line 3-3 of Fig. 1.

The present embodiment of my invention comprises a ventilator having a horizontally disposed flue or air-passage, a vertically disposed flue or air-passage adjacent thereto and communicating therewith; and preferably, although not necessarily, a screen wall or partition separating the horizontally disposed flue from the vertically disposed flue.

It will be clearly understood that while I have produced a ventilator which will prevent sudden cold drafts entering the room, I have so arranged the ventilator as to permit a perfectly free up-draft through the ventilator, regardless of the direction of the wind, and one that will exclude all storms.

In the drawings, the reference numeral 1 designates a horizontal flue or air-passage and 2 is a suitable vertically disposed flue or air-passage. Flue 1 is adjacent to and communicates at one end with flue 2 and at its opposite end with a room over the usual window-sash 3. Flue 1 is housed by means of the side walls 1 and the top and bottom walls 5 and 6 respectively. The top wall 5 is preferably inclined as shown, to allow ready drainage. Flue 2 is housed by means of the end walls, 6, preferably integral with the end walls 4, the front glass closure 7 and the top glass closure 8. Preferably I use glass closures, but other styles of closures may be used if desired.

The end walls6 are adapted to extend upwardly a suitable distance above the top edge of the end walls 4, and are preferably inclined or beveled upwardly from the front closure 7, thus providing a rear air-outlet passage 9 for flue 2, which has its bottom open to permit of a free upward circulation of air.

The end walls 4 and the top and bottom walls 5 and 6 respectively, are adapted to be suitably secured to the window frame 10, thus forming a channel or air space 11 be-. tween the wall of the building and the rear air-outlet opening 9.

. A suitable, preferably removable, screen wall or partition 12 is arranged at the end of flue 2 communicating with flue 1, to prevent vermin, etc., from entering the room.

From an inspection of the drawings, it will be observed that the fresh air is conveyed into the room from over the top of the window sash 3 from the flues 1 and 2. Flue 1 communicates at one end with the interior of the room over the window sash 3, as clearly shown in Fig. 2 and the freshair is carried to the breathing plane and beyond, where it is gradually diffused over the entire area, while the foul, impure air is conveyed out through flue 1 into flue 2, which latter flue conveys it upwardlv and allows it to pass outwardly through the rear air-outlet 9. Down drafts are deflected by the inclined top closures, thus sudden plold drafts are stopped from entering either It will be noted that by raising or lowerseeii that I provide a simple, yet efficient means for thoroughly ventilating a room.

Having described my invention, what I claim and desire to secure by Letters Patent is:

p 1. A ventilator comprising a flue adapted to have communication with a room, and a vertical flue having an air-inlet and airoutlet communicating with said first-mentioned flue, the rear wall of said vertical flue spaced apart from the wall of said room and provided with an air-outlet passage; a forwardly sloping top on said vertical flue, and a screen interposed between said flues.

2. The combination with a window-frame andsliding sash carried thereby, of a ventilating-hood secured to said window-frame comprising a screen flue adapted to communicate with a room over said sliding-sash, a second flue having a vertical passage in communication with said first-mentioned flue, said second-mentioned flue having its rear wall spaced apart from said window frame and having an inclined top and a lower air-inlet passage and an upper rear air-outlet opening opposite said windowframe.

In testimony whereof, I aflix my signature in presence of two witnesses CHARLES SAUNDERS Witnesses FREDK. J. LARSON, RoY WALLIS.
