Application November 17, 1939, Serial No. 394,935

1 Claim. (CI. 98-88) My invention relates to ventilator construction; and particularly to a building construction wherein a ventilator is built into a building wall in association with a window, but functioning independently thereof.

It is among the objects of my invention to provide a ventilator mounted in the space between a window and the floor of a room for effecting ventilation without opening the win" dow.

Another object is to provide a building construction wherein a single frame inset in the wall of a building is arranged to receive one or more units of window sash, and also a ventilator by which ventilation may be controlled independently of the window.

Another object is to provide a ventilator mounted in an extension of a window frame without interference with the mounting and operation of the window sash; and provided with a door serving the double purpose. of controlling ventilation and deflecting drafts.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of my invention. It is to be understood that I do not limit myself to this disclosure of species of my invention, as I may adopt variant embodiments thereof within the scope of the claim.

In the drawing:

Figure 1 is a vertical section of a portion of a building having the ventilator of my invention built therein, portions being broken away.

Figure 2 is a fragmental elevational view showing the ventilator construction of my invention as viewed from the inside of a room, portions of the ventilator door and screen being broken away.

Figure 3 is an elevational view of the ventilator, and the lower portion of the frame into which it is built, as viewed from the outer side.

In terms of broad inclusion, the ventilator construction of my invention comprises a louver built into a building wall between a Window and the floor of a room and provided with a door movable to open and close the louver, and to provide a draft deflector when the ventilator door is open. Preferably the louver is built into an extension of a window frame of otherwise more or less standard construction, without interfering with the mounting or operation of the window sash mounted in the frame; the louver being arranged to permit controlled ventilation independently of the window;

In terms of greater detail, the device of my invention comprises a louver designated in general by the numeral l, inset in the wall 2. of a building, preferably between the bottom of a window 3 and the floor 4 of a room. In the preferred embodiment illustrated in the drawing, the louver I is built into an extension 6 of a window frame I of the character commonly fabricated at a planing mill for mounting in the wall construction of a building.

The frame I with its extension 6 comprises a pair of side members 8 connected at their upper ends by a suitable top member 9. At their lower ends, the side members 8 are secured to a main sill l.| similar to the sills commonly provided in the ordinary window frame. A transom-bar I2 is mounted across the frame in spaced relation to the main sill II The transom-bar [2 serves as a secondary sill at the bottom of the main frame I and top of the extension 6. Facing members l3 and M are secured to the top member 9 and side members 8 respectively, as in the ordinary window frame construction. V

The main frame. portion 1 is arranged to receive one or more units of window sash l6, mounted therein in accordance with standard practice. In the drawing I have illustrated the conventional double sliding sash arrangement; but single or double hinged sash, or other types of sash and sash mountings may be substituted. The transom-bar E2 or secondary sill serves as the sill for the window, and performs the functions of the ordinary window sill.

The louver l is formed by a plurality of spaced louver boards I! extending transversely across the extension -6 of the frame. Preferably the louver boards l! are made of strips of wood set at an appropriate angle with their ends rabbetted into the side members 8. Metal strips, secured in any suitable manner, may be substituted if desired. The term louver board is used herein in a generic sense inclusive of louver strips of wood, metal or other material, secured in any convenient manner,

The louver boards I! are preferably arranged with their outer lower edges substantially flush with the outer edges of the side frame members 8. The upper inner edges of the boards I! are spaced inwardly from the inner edges of the frame members 8; and a screen I8 is preferably mounted to cover the louver openings. The screen 18 may be mounted in any suitable manher, but I prefer to secure it to a frame l9 removably fitted into the frame extension 6. The frame may seat against the inner edges of the louver boards [1, and may be held in place by a suitable spring catch 2|.

A door 22 is hingedly mounted to cover the inner side of the louver I. In the preferred embodiment illustrated in the drawing, the door 22 is mounted between the side frame members 8 upon pivot pins 23 near the lower edge of the door. The lower edge of the door is received in a recess 24 formed in the inner edge of the main sill H. In its closed position, the door preferably abuts against the screen frame l9, and may be held in closed position by a suitable spring catch 26.

The frame 1 with its extension 6 is set in a building wall in accordance with the standard practice of mounting window frames. Because of the increased length of the frame, due to the extension 6 thereof, the main sill may rest directly upon the stud plate 21 of the wall, or upon a plate secured at any desired height thereabove. The transom-bar or secondary sill I2 is positioned at the level ordinarily occupied by the window sill, and at a desired height above the floor 4. The frame is secured in place, and the usual outer and inner trim 29 and 30 is applied in accordance with standard practice.

In installations where the frame extension 6 extends substantially to the floor 4, the usual base-board 3| may provide the inner trim at the bottom of the frame. The base-board 3 l, or other trim, preferably terminates slightly below the level of the pivot pins 23 so that the door 22 may be swung inwardly thereover to an open position, as indicated in Figure l of the drawing.

In the completed structure, the window sash l6 may be operated in the usual manner above the transom-bar or secondary sill l2; without being in any way affected by the louver I,

In its closed position, the louver door 22 is substantially flush with the wall, and does not obstruct free access to the window. When the door 22 is moved to an open position, ventilation may be obtained through the louver I without the need of opening the window, thereby mini- 2,320,268 v p r. l

mizing damage to curtains or drapes hung over the window, and permitting the window to be kept locked.

Preferably the movement of the door 22 is limited so that, in its open position, it will incline inwardly and upwardly into the room to provide a draft deflector. The recess 24 may be so shaped as to limit the movement of the lower edge of the door 22 therein, and thereby provide a stop 32 by which the door may be held in its draft deflecting position; or other stop means of any suitable character may be provided.

The arrangement of the louver boards prevents the entrance of rain; and the screen l8 not only excludes insects, but serves to collect moisture from fog or damp atmosphere and thereby reduces the entrance of moisture of that character. Being built directly into a unitary frame with the window, the ventilator may be easily and economically installed; and utilizes the ordinarily wasted wall space below a window for ventilating purposes without obstructing or disfiguring the window itself.

I claim:

A combined window and ventilator casement fabricated as a unit for installation in a building wall and comprising a pair of uniformly spaced side members connected at their upper ends by a top frame member and at their lower ends by a louver sill, a window sill secured to the side members at a level above the louver sill, said window sill dividing the casement into an upper sash receiving portion and a lower ventilator portion, louver boards extending transversely across the ventilator portion with their ends secured directly to the'side members, and a, door pivoted at its lower edge upon the inner side of the casement for covering the ventilator portion, the inner edge of the louver sill being recessed to receive the lower edge of the door and provided with a shoulder for limiting opening movement thereof.

orro PAUL CRAMER.
