Patented Oct. 29, 1935 ITED STAT PATENT OFFICE COMBINED WINDOW SCREEN AND VENTILATOR 2 Claims.

The invention relates to a window ventilator, and has for its object to provide a box adapted to be disposed between the lower sash and window stool or ledge, said box being arranged to freely permit air and light to enter the room but to exclude rain and intruders, insects, etc., and to control said air, and having adjustable extensions at the ends so that it may have lengths equal to the widths of window sash so as to be easily detachably fitted to any type window to prevent displacement.

Another object is to provide a guard of the character described whereby the current of air admitted through the window will be deflected upwardly and its quantity controlled to protect the occupants of the room from the direct draft and outside atmospheric changes heretofore annoying.

Another object of the invention resides in the provision of a Window ventilator which may be cheaply constructed and completely closed when desired, which may have a removable glass member and which will have shelf means for the lower sash to rest thereon to prevent drafts usually passing under the sash.

With the foregoing and other objects in View, the invention presents a new and novel construction and combination of parts described and shown in the accompanying drawing forming a material part of this disclosure and in which,

Fig. 1 is a top plan view of the device Fig. 2 is a front view thereof,

Fig. 3 illustrates, in perspective, a fragmentary portion thereof,

Fig. 4 is a sectional View through the venti1a tor taken on the line 44 Fig. 1.

In the drawing the numeral I, designates the side member of a window casing having the inside grooves 2, in which the sash 3, slides, and the bottom ledge 4. These parts are of conventional construction.

In the form shown the ventilator I0, is box shaped and must be made of different lengths to accommodate window openings of varying widths. My slideable end pieces II, and I2, provide reasonable amount of adjustment, said pieces being slideable in the groove [3, formed between the cover l4, and the box end flanges. Formed integrally with the cover I4, is the extending shelf 15, providing resting means for the sash 3, and arranged to prevent drafts under said sash, the back l6, of said extending shelf aiding in this respect.

The cover I4, is provided with spaced screened openings l1, and mounted slideably on this cover,

as at 33, is the shutter l8, provided with openings I 9 adapted to be moved into and out of registration with the openings II, by means of the knob or handle 20, carried by or formed integral with said shutter. Stops 2!, are provided limiting the movement of the shutter to from completely closed to open position. The screen 22, may be formed integral of the cover, or separately, of a foraminous material, as shown in Figure 4. When separately formed the screen 10 may be fastened to the cover by preferably pointed depressed tongues 23, formed integral with the cover and bent around or through the screen holding it in place.

The glass 2 is from the room side, preferably removably mounted to the ventilator, grooves being arranged at the ends of the ventilator as at 25, and at the bottom as at 26. It is readily seen that light is not obstructed by my ventilator and that the arrangement and fastening of the glass prevents water, drafts etc., from entering the room.

The bottom 28, is formed so as to fit the easing to exclude water, etc., from entering the room and its lower edge 29, is preferably turned downwardly and adapted to fit against the other edge of the ledge 4.

The outer vertical wall 30, of the ventilator I0, is provided with one or more apertures 3|, to act as the intake manifold and the air is directed upwards through the adjustable and screened ports I! and I9, in to the room. It will be seen that any draft of air will be deflected upwardly into the room, this obviously being a desired feature.

In use the ventilator is located inside the window on the ledge 4, with the flange 29, resting against the outer edge of said ledge and the end pieces II and I2, resting in the sash grooves 2. 4 The lower sash is then pulled down to rest on the shelf i5, and on said end pieces, thus more firmly holding the ventilator in place. The shutter I8, is adjusted as required. The ventilator may be fastened to the sill with suitable fastening means at the bottom and may also look itself to the sash by means of a locking means such as at 32.

As many apparently widely different embodiments of the invention could be devised without departing from the scope thereof it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

I claim,

1. In a ventilator rectangular in cross sectional contour having an aperture in the outer side and screened apertures in the cover; a shutter, having openings therein, horizontally slidably mounted in tracks formed integral with the cover and adapted to be moved into and out of registration with said screened cover apertures; a sash supporting shelf member integral with the cover set below the top of the ventilator; a deflector member on the inner side upwardly and unobstructively removable from its position in the ventilator permitting lateral entry into the interior of the ventilator when so removed,lend posts, slideable with respect to said ventilator, in a groove formed between the ventilator outer frame side and the vertical flange part of said sash supporting shelf to increase the eifective length of the ventilator, a base member having a flange for engagement with the window sill, and means for locking said sash and window to said ventilator.

2. In a building window ventilator rectangular and unobstructively removable from its position 10 between the back flange of the cover and said ventilator inner frame side permitting lateral entry into the interior of the ventilator when the deflector is removed; end posts, slideable in 15 a groove, inherently formed by the ventilator outer frame side and the vertical flange part of said sash supporting shelf, to increase the effective length of the ventilator; a base member having a flange for engagement with the window 20 sill; and means for locking said sash and window to said ventilator.
