Specification of Letters Patent.

Patented Mar.. it., 191W.

Application filed December 14, 1908. Serial No. 467,325.

To alt whom 'it may concern: l

Be it known that I, LEWIS J." CARNEY, a citizen of the United States, residing at Boston, county of Suffolk, Commonwealth of lilassacliusetts,have invented certain new and useful Improvements in Ventilators, of which the following is a specification. j

rlhis invention relates to ventilators vand particularly to window ventilators. In devices of this sort it is of great importance that the ventilator be readily applied to windows of varying width without the necessity of exact measurements or close fitting requiring cutting or sawing on the spot. It is also desirable that such devices be positionable in the window so as to be held therein in such a way that no draft shall be permitted through cracks and so firmly adjusted to the window as to relieve the ventilator from the risk of being crushed or disabled by the descending sash.

To the end, therefore, of producing a ventilator which shall have these several advantages and possibilities I have devised my present ventilator in which I have included various features of structural advantage and improvement. All this will be more fully set forth and described in the specification which follows in which I have described a certain ventilatoras illustrative of my invention and have shown the same in the drawings as an embodiment thereof.

rllhroughout the drawings and the description like reference numerals are employed to indicate corresponding parts and in the drawings Figure 1 is a view showing ,the direct draft closed, Fig. 2 is a view showing the indirect draft closed and the direct draft opened, Fig. 3 is a front view of a portionofv a window from without with the ventilator applied, and Fig. 4 is a side sectional view on the line 4-4, Fig. 1.

1 isthe outside wall, 2 the top, 3 the inside wall, and 4 the bottom of a ventilator box which is closed by ends 5. In the outside Wall 1 are air ports 6 grouped near the middle of the ventilator box and in the top 2 are nine ports 7 spaced along the entire distance. The upper edges of the sides 1 and 3 are extended and grooved at 11 and 31 to form a slide Way in which Work three slides 8 each pierced by a pair of 'ports 9.

to make it possible to open the three central ports 7 or close these three and open either or both of the sets of 3 ports at each end, or

to-open all of the ports 7 at once. In this way it is possible to open the middle groups giving a direct. draft or to close the middle group and open one or both end groups to secure an indirect draft'or to open all to secure a full draft.`

At eachend of the ventilator box I pro- V vide a wing 10 of about vthe width of ,thev

box but attached to it so. as to depend Y- slightly below its lower edge; The wing is vertically slotted at 11 and is adjustably fastened .by a bolt and thumbnut to the box through a horizontal slot -12 which per'- mits its adjustment in two directions. In`

order to adjust the ventilator to a window, therefore, the thumbnuts at 13 are slackened and the wings pushed down until the ventilator box rests in the inside window sill and the bottom of the wings rest on the outer sill or ledge. This affords a firm seat for the ventilator b ox and a suitable rest vlfor the wings 10 so that there is no danger of the box becoming displaced and crushed by a descending sash or of the wings 1() beingy v1. In a window ventilator a Ventilating l box having air passages therethrough and vertically adjustable lateral Wings'for receiving the sash. i

2. In a window. ventilator a Ventilating `box adapted to rest on a Window sill within the line of the sash and having air passages therethrough, a pro vertically adjustable on the outer face o said box and adapted to be positioned with its lower edge against the outer sill in line with the sash to receive said sash and support it upon its upper edge.

3. In a window ventilator a Ventilating l box having air passages therethrough and lateral wings vertically and horizontally adjustable thereon.

These ports are so arranged in the slides as j 4. In a ,window ventilator a Ventilating box and means adjustable relative thereto for supporting a sash when said box is in contact With a window sill.

5. In a window support a Ventilating box, an intake port in its outside wall centrally ot the ends thereof, ports in the top of said box arranged centrally and at each end thereof and means for closing said ports independent l G yIn a window ventilator a Ventilatingr box having intake ports centrally arranged in its outer wall, a plurality of escape ports disposed throughout the length of another wall of the box and means for closing the ports adjacent to said intake ports.

7. Inra device of the class described, a

Ventilating sill-box adapted to be disposed inside of the line of the sash and a wing adjustably mounted on the outer face of said ventilator for Vertical or horizontal movement thereon and adapted to have its upper edge disposed below the top of said vent-ilator.

8. In a device of the class described, a Ventilating sill-box adapted to be disposed inside of the line of the sash and a Wing adjustably mounted on the outside face of said ventilator for vertical or horizontal movement thereon and adapted to have its upper edge disposed below the top of said ventilator and its lower edge adapted to englage the -sill below the bottom of the sas i.

9. In a window ventilator a ventilator box and means for supporting the sash, said means being independent of said box and vertically adjustable thereto.

10. In a window ventilator, an inside sillbox and an outside flange piece vertically adjustable on said box to fit the thickness of the window sill.

11. A device of the class described, comprising a ventilator box and means for securing a draft, directly or indirectly therethrough.

In testimony whereof, I affix my signature in presence of two Witnesses.

LEWIS J. CARNEY.
