Beit known that I, MORTIMER KINZEY, a

' citizen of the United States,-residing at New?` ark, in the county of Essex and State of New Jersey, have invented certain 'new and useful. Improvements in ventilators, of which the vfollowing is a specification, reference' being had therein to theaocompanying drawings,

This invention relates to improvements in ventilators, and has for its primary obj ect the provision of a device of thisfcharacter which will be adapted to fit windows as ordinarily installed and of various sizes and also ISy f tical embodiment of the invention comprises I be susceptible of ei'lcient use either in fixed v moving With the foregoing object in view a prac-i a supporting-frame, a casing carried thereby;4 preferably arrangedonv the inside 'of the frame and having an exit-opening at its top;

" oppositely disposed inlet openings facing outwardlyfrom the frame, and a balanced 'horizontallyfdisposed movable delector in' the casing beneath the exit-o ening thereof;

. and intermediate the opposite y-dispesed in let-openings, said deflector being balanced, s0'

as'to be highly sensitive to any gust or per-| ceptible air-current' and to close toward the incoming air to prevent direct escape thereof through Ythe exit-opening 0n the interior of the device, such movement causing said air to pass through the casing and out of the op posite opening, therebycreating a suction, or

opposite draft from theroomor `car`- Under normal conditions-as, for instance, when a "caris at a standstill, and in thexcaseof a house when there is no perceptible air-'current without-'the deflector will assume -its normal or trueliorizontal position to permit a lightl comfortable ingress of air through,

both ofthe inlet-openings into the casing and -'thence throughthe exit-opening of said casing into the room or car'. i

Th foregoing, as Well as other-novel de-v l t'ail'sin the construction and arrangement of the partsof the ventilator, will be apparent from the detailed description hereinafter given when read in connection with the accompanying drawings, forming part hereof,

wherein a vconvenient embodiment of the in-- vention is illustrated.

In the drawings, Figure lis a perspective Referring more speciiically to the draw-"y ings, wherein like reference characters refer to corresponding parts in the several views,- A designates a convenient supporting-frame,

which maybe readily formed of wood or any other material suitable to the conditions :ati tendin the use for which. itis provided, said frame aving an extensible section B at one 'end adjustable through the medium of a slota'n'd-,scr'ew connection C, whereby the frame may be adjusted with respect to its length toH iit window-casings of various widths a given range;

On the inside 0f the frame I mount a'ca'sing D, preferably formed off'm'etal o f-a style and color to agree with the surrondings attending its use, tlie'ends of said .casing inwardly toward each other, asat E. Thevtop wall of this casing is provided withan openingto aff' ford ready passage of air therethrough intofa room or the like,`sa id opening being screened,`

as represented at F.

G Gr are box-likeinlets projecting outwardly slightly beyond the outer'surface of ner ends with Opposite ends of the casing, these inlets'being also preferably directly opposite the inclined wal s of the casing, wherey the air admitted through the-inlet willige deflected inwardly and longitudinally-fof' casing by said inclined 'walls l`The, 'uter? lthe frame A and communicating at their inare screened, as at H, and are each 'inclined inwardly and toward the end of the device at which it is located, whereby theyv face'iiifopposite directions, as clearly shownpin Figs. 3` and 4. f

Within the casing, beneath the o ening constituting' the eXit therefrom and a so intermediate the inlet-openings G G', a pivoted ICO deiiector I is supported upon the pivot J, the pivot being centrally arranged and the opposite ends of the deiiector being balanced, whereby its normal position is in a horizontal plane and longitudinally of the casing. As

shown, this deilector is of somewhat angular formation, the endsthereof being turned upwardly toward the top of the casing for a purpose as will presently appear.

The position of the arts being assumed to be that last above de ed, when there is no perceptible air-current on the outside both of the inlets Gr G may admit to an agreeable extent air into the casing, from which latter it Will escape through Vits exit-opening into the room or car.` When, however, there is a suddengust of wind or a perceptible current .of air Without `the device, `the same will enter the `inlet-opening Gor Gr, facing in the direction opposite to the direction of flow of the air, and owing to the impingment of the air upon the nearest upturned end of the deiiector the same will be 'rocked into the position indicated in Fig, whereby to .close the exit-opening of the casing against said aircurrent, thereby compelling the same to pass on through the `casing and out of the opposite opening 'G or G', as the case may be, the latter under these conditions servingvas an .exitopening, .as is obvious, with the resultant effect that a vacuum for outdraft from the room through the casing is secured. Of course when the ventilator is employed on moving vehicles, such as railway passengercars, the deflector .occupies one of its shifted positions continuously during the movement of the train and the device operates as an eX- h-aust. However, when the train is at a standstill the operation is just the same as when the ventilator is used ina xed structure.

`It .is to be understood that the invention `is :susceptible of other embodiments than that disclosed herein and also .that the form-of device shown may bealtered `and changed without departing `from the spirit ofthe invention.

Having thus described the invention, what is claimed as new, .and desired to be secured by Letters Patent, is-

l, In `a ventilator of the character dei scribed, `a casing having closed ends and a pair of oppositely-disposed inlet openings, and an .exit-opening, the ends of said casing being inclined toward the outlet-opening, and the inlet-openings being opposite and at an angle to said inclined ends whereby to delect the air inwardly, and a movable delector in said casing intermediate said inletopenings.

2. In va ventilator of the character described, a casing having-closed ends an inlet- .opening ateach end,\and an exit-opening, the `end Walls of said casing being inclined toward the exit-opening, and the inlet-openings being opposite and at an angle to said inclined end walls.

3. In a ventilator of the character described, a supporting-frame, a casing secured to one side ofsaid frame, said casing having an exit-opening, a balanced deiiector mounted within the casing, and oppositely-disposed box-like inlets mounted upon the other side of the frame and communicating therethrough with the interior of the casing.

4. In a ventilator of the character described, a supporting-frame, a casing secured to -one side of said frame, said `casing having closed ends and also having .an exit-o ening, a balanced delector mounted within t e casing., and oppositely-disposed box-like inlets mounted upon the kother side of the frame ,and communicating therethrough with the interior of the casing, the end walls :of the casing directly opposite the inlets `being inclined toward the exit-opening of said casing.
