WINDOW-VENTILATOR.

Specification of Letters Patent.

Application filed December 4, 1912. Serial No. 734,997.

Aful Window-Ventilator, of lwhich the following is the specification.

My invention has for its object the construction of a ventilator adapted for application to a window, and which can be readily placed in position or removed therefrom, andby means of which air may be admitted in regulated volume and free from drafts to the dwelling, car, or other structure to the windows of which my device is applied. v

A lfurther object of my invention is the construction of a device of this kind equipped with means whereby the air passing therethrough is freed from dust or other foreign substances.

With these and other objects in View my invention consists in certain constructions, combinations and arrangements of parts, the preferred embodiment ofwhich willnbe hereinafter fully described in connection with theaccompanying drawing'and pointed out in the claims.

In the accompanying drawing wherein like parts are designated by the same reference numerals wherever they occur, Figure 1 is a perspective view of theinsideof a window-frame' and sash and showing-my improved ventilator applied thereto; Fig. 2

Vis a partly broken view of the defiectlng` member forming the front of'my device and showing a screen-framepivoted Aon the inner side thereof, and Fig.3 is a central cross sectional view.

L1 designates a lwindow-framed@ a window-sash and 7 a window-sill, ali of the usual construction. The sash is shown as raised a sufficient distance to provide a space in which my improved ventilator is placed.

8 designates a' partition board ,adapted to be inserted under a raised window, and which is provided at itslower and upper edges with strips 9. Between' the 'ends of the strips v9 is an opening 10, and which is covered at the rear by a downwardly-depending hood ll'attached to the outer side of the plate 8. Secured to the lowerstrip 9 and' extending inwardly therefrom isa bottom board l2, of a length equal tothe opening 10, and extending beneath said board and secured to the inner face of said 4lower strip 9 is a filler piece 13, of a width adapted to rest on the top of the windowsill 7, when the device is in place.

To the plate 8, at each end of the openin 10 therein, are secured end pieces 14, pre erably having their front edges inclined as shown. Pivoted between the said end pieces 14 is a swinging detlecting member 15 pivotally connected with lthe end-pieces 14 bypivots 16, and carryin on its rear face 1a screen-frame 17 hinge thereto by suitable hinges 18. A hook 19 is provided, whereby the said screen-frame may be secured against the inner face of the delecting member 15 or permitted to tilt therefrom, with its upper edge resting against the upper strip 9. L

20 designates a rack-bar connected at its rear end to theupper strip 9 of the plate 8, its front end passing through an opening in the ear 21 on the upper edge of the deflecting member 15, with the teeth on the.

rack-bar enga ng such opening, whereby the angle of t e deflecting member can be adjusted to regulate the quantity of air Patented Nov. 11, 1913.

passing through the ventilator. Extending l across the rear of the opening 10 is a wirescreen 22 which, in connection with the screen 17 pivoted on the rear ofthe deiecting member 15, serves to effectively screen all dust or other foreign matter from the air passing through the ventilator. When the device is placed in a window the deflectying member 15 is tilted outwardly the desired distance and secured at such angle by the rack-bar 20. The screen-frame 17 on the rear of the detlecting member 15 is permitted to swing rearwardly against the faoe of the upper strip 9. Air willnow pass under the hood 11 and through the screen sections 22 and 17 and be deflected upwardly into the room by the deiiecting member 15, thereby preventing all direct draft.

As' will be seen my device is simple in Aconstruction and inexpensive in cost of construction, and will eifectively serve the purpose for which it is designed.`

I am aware that considerable variation is possible in the details of construction herein shown and described, without departing from the spirit of myinvention, and I do not intend to limit myself thereto, except as pointed out in the following claims, in which it is my intention to claim all the novelty inherent in the structure shown and described as broadly as the state of the art will permit.

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

1. A Ventilating device, comprising a partition board having an opening therethrough and adapted to be inserted beneath a Window sash, a hood attached to the rear of said board, a screen section covering the rear of said opening, members secured to the front of said board and iianking the opening therein, a def'lecting member pivot-ally connected between said members, and a screen member hingedly connected to the rear of said deiecting member.

2. A Ventilating device, comprising a partit-ion board having an opening therethrough and adapted to be inserted beneath a Window sash, a hood attached to the rear of said board, a screen section covering the rear of said opening, members secured to the front of said board and flanking the opening therein, a delecting member pivotally connected between said members, a screen member hingediy connected to the rear of said defiectinfr member, and means connecting said deecting member With said board whereby the defieoting member may be adjusted at varying angles thereto, for the purpose set forth.
