1 Claim.

This invention relates to window ventilators, and more particularly to window ventilators of the portable type.

An important object of the invention is to provide a ventilator which may be readily positioned within a window frame, and held in such position by contact with the window sash or other suitable means, not shown.

Another object of the invention is the provision of means to regulate the quantity of air passing through the ventilator, together with means for defiecting the air prior to its passage into the room ventilated, thereby providing an indirect draft Ventilator.

Still another object of the invention is to provide means which will exclude rain, snow and sleet, and at the same time admit air in the desired quantities, eliminating direct drafts.

With the foregoing 'and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described,

- may be made within the scope of what is claimed,

without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is an elevational View of a window ventilator constructed in accordance with the invention.

Figure 2 is a front elevational View thereof.

Figure 3 is a sectional View taken on line 3- -3 of Figure 1.

Figure 4 is a sectional View taken on line 4 4 of Figure 1.

Figure 5 is a sectional View taken on line 5--5 of Figure 1.

Referring to the drawings in detail, the ventilator comprises a substantially rectangular frame indicated generally by the reference charwithin the frame 5, are members II that are formed with openings I2 that align, as shown by Figure 3. Between the members II, is a wire mesh member I 3 that acts as a screen to prevent inserts and other foreign matter, from passing through the openings I2. Disposed within the frame, and arranged at the opposite side thereof, is a member I4 which is also formed with openings that align with the openings I2. The space between the members I4 and I I providing a guide- Way for the movable ventilator slide i5. As shown, the slide I5 is formed with openings I6 that are of diameters equal to the openings of the members I I and I4, so that when the slide is moved upwardly to its limit, the openings Iii of the slide I5 will register with the opening of the members II and I4 providing passageways through which air passes into the room ventilated by the device. An operating arm indicated at I'I is secured to the ventilator slide I5, and is so disposed that it extends into the room where it will be readily accessible by persons desiring to oper- A ate the ventilator slide to adjust the sizes of the acter 5, the frame being preferably constructed of sheet metal material, so that it may be readily and easily stamped by a single stamping operation of a metal stamping machine.

As shown, the frame embodies spaced flanges 6 and i, the flange 1 being formed with inwardly extended portions 8, the upper inwardly extended portion 8 being inclined downwardly, as clearly shown by Figure 3 of the drawings. A partitioning member 9 is positioned between the flanges I0 that form side members for the flanges 8, and divides the space between the anges I0, into upper and lower passageways. Mounted openings to regulate the through the ventilator.

The reference character I8 designates rods that are mounted in openings formed in the flanges I8, the rods providing supports for the shutters I9 that are of lengths to extend between the iianges IU at opposite ends of the ventilator frame. Ofiset ends 20 are formed on the rods I8, and these offset ends are connected by the link 2l so that the rodsare operated simultaneously to adjust the shutters, at the will of the operator.

Secured to the link 2I, at a point intermediate the ends thereof, is a rod. 22 that is formed with a threaded end on which the nut 23 is mounted This rod 22 moves through the elongated opening 24 formed in the frame of the ventilator, and by means of which the rods iS may be rotated. It will of course be understood that as the rods are rotated, the shutters are moved to various angles with respect to the ventilator openings, to the end that air passing through the ventilator openings may be deflected, to meet various atmospherical conditions.

From the foregoing it will be seen that due to the construction shown and described, the vene tilator slide I5 may be adjusted vertically to regulate the amount of air passing through the openings of the ventilator to insure the proper ventilation, according to the amount of wind pressure. In addition to the adjustment of the openings, the shutters may be adjusted to various angular positions to deflect the air passing quantity of air passing through the openings as a temporary adjustment in the control of the air passing through the ventilator.

It will of course be understood that after the shutters have been properly adjusted, the shutters may be held in their positions of adjustment, by tightening the nut 23.

What is claimed is:

A window ventilator comprising a frame adapted to be positioned between a Window sash and its sill, spaced stationary members Within the frame, said spaced stationary members having aligning openings, a movable member having openings, disposed Within the space between the stationary members, the openings of the movable member adapted to align with the openings of the stationary members admitting air through the ventilator, Wide downwardly inclined flanges extending forwardly from the frame and providing a hood, wide horizontally disposed shutter members pivotally mounted Within the hood and disposed in spaced relation with the openings of the stationary members, said shutters being disposed in direct alignment with the openings of the ventilator, said shutters adapted to be adjusted to obstruct the passage of air through the aligning openings, and means for operating the shutters simultaneously.
