VENTILATOR APPARATUS Filed June 28, 1942 M. JENNEss Patented Aug. 8, 1944 UNITED 4 STATES OFFICE 2355586 v 'i vEN'riLA'roit Arr'ARA'rUS v- Langdon M. Jenness, Chicago, Ill.

Application June 26, 1942, Serial No. 448,537

(cl. sis-99.8)

1 Claim.

This invention relates generally to ventilator apparatus and in particular to a ventilator apparatus of a type adapted to be extended across a window frame between the bottom rail of a window and the sill for such window.

ventilators of this type in the prior art gen-l erally include an extensible vented body member having the bottom resting on the window sill and the top in abutting engagement with the bottom window rail. These .ventilators are not entirely satisfactory because rain generally passes between the top of the ventilator and the window and runs down the inner side or face of the ventilator to the window sill, from where it usually' drains under the stool and onto the wall in` which the window is located. Any water passing through the ventilator vents also runs down the inner face of the ventilator to augment the leakage at the top of the ventilator. This condition i is aggravated when the window is equipped with weather stripping including 'an upstanding tongue or weather strip on the window sill adapted to be received in aigroove in the bottom rail of the Window when the window is in a closed position. The bottom of these prior art ventilators is usually positioned to the inside of the weather strip and adjacent the window stool. In other words the ventilator bottom rests on the sill intermediate the weather strip and the window stool. Upon the occurrence of water leakage, as above explained, the water is prevented from flowing off the window sill toward the outside of the window by the weather strip which cooperates with the window stool to form a water pocket or reservoir at the bottom of the ventilator. The water from the reservoir drains under the stool, it being understood that in the usual prior art ventilators the water is able to pass between the bottom of the ventilator and the window sill. Further any water running down the outer side of the ventilator also collects in this reservoir to drain under the stool and onto the wall to the inside of the window.

It is an object of this invention, therefore, to provide an improved ventilator apparatus.

Another object of this invention is to provide ventilator apparatus adapted to be installed between the bottom rail of the window and sill therefor which prevents water leakage at the top and drains any water running down the inner face thereof to the outside of the window. Leakage of water about the window stool is thus positively eliminated.

A further object of this invention is to provide a ventilator for a window which is adapted to cooperate with a weather stripping for the vwindow to prevent any leakage of water to the inside of the window.

A feature of this invention is found in the provision of a ventilator for a window in which a water' carrying portion co-extensive in length with the ventilator is formed at the bottom thereof to collect any water running down the inner face thereof. Openings or seep holes in a wall of the water carrying portion drain the water thus collected to'the outside of the window and away from the window stool.

Further objects, features and advantages of this invention will become apparent from the following description when taken in connection with the acco'mpanying drawing in which:

Fig. 1 shows the vassembly of one from of the invention with an associated m'ndow;

Fig. 2 is an enlarged sectional view as seen along the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary view in perspective showing the structure of the bottom portion of the ventilator of this invention as illustrated in Figs. 1 and 2.

With reference to the drawing there is shown in Figs. 1 and 2 a window or sash Ill of double hung type having a lower rail ll and stiles |2 vertically slidable in a window frame |3 having a sill portion |4. The window is illustrated as being weather conditioned with a groove IB formed in the bottom rail adapted to receive therein, when the window is in a closed position, an upstanding tongue or weather strip I'l carried r on the sill |4. The ventilator of this invention is adapted, when the window is in an open position, to be installed between the lower rail and the sill M.

The ventilator includes a body portion comprised of a pair of extensible Sections or plates |8 and |9 which are in telescoped engagement, as indicated at 20 in Figs. 1 and 3, at the tops and bottoms thereof. Each ventilator section is provided with a handle portion 2| on the inner side thereof and vents 22 which are punched or stamped out therein, the punched out portions being projected from the outer face of the ventilator Sections in a usual manner. The upper part of the ventilator, as best shown in Fig. 2, is ofv a somewhat angulate shape with a straight top portion 23 parallel to the main body portion of the ventilator but off set away from the inner face thereof by a connecting portion 25. The lower part of the ventilator body portion is ntegrally formed on the inner face thereof with a substantially channel or trough shaped portion 24.

In the assembly of the ventilator the top portion 23 is positioned within the groove IS of the window rail l I with the channel portion 24 located adjacent the weather strip |1 and to the outside thereof. By means of the handles 2| the sections |8 and |9 are moved away from each other and into engagement with corresponding sides of the window frame l3 so as to extend completely thereacross. The ventilator is held in its assembly position by pushing the window down thereon in a well known manner. With the top portion 23 within the groove IG the outer side 30 of the window rail overhangs such portion while the under side, en-

gages substantially the connecting portion 25. This relative assembly of the ventilator top with is positively prevented from traveling inwardly beyond the weather strip l'l so as to prevent any seepage of water about the stool 21 and onto the wall 28 to the inside of the window Ill.

From a consideration of the above description and the drawing, therefore, it is seen that the invention provides a ventilator which is of a simple and rugged construction, adapted to be easily assembled in windows with or without weather conditioning provisions, and which functions to positively eliminate water leakage inwardly of the window with which it is associated.

`ment thereof it is to be understood that it is not to be so limited since modifications and alterai tions can be made therein which are within the the window rail positively prevents any leakage of water between the window and the ventilator. Any water which might pass through the vents 22 and onto the inner face of the ventilator travels downwardly on this face into the water carrying portion 24 at the bottom thereof. Drain or seep holes 2B (Figs. 2 and 3) are provided in the body portion of the ventilator, which forms an outer wall for the water carrying portion, for draining water therefrom to the outside of the window and away from the weather strip l'l. By virtue of the ventilator bottom being located `acljacent but to the outside of the weather strip I'l, such strip cooperates with the liquid. carrying portion lto prevent any leakage of waterv inwardly thereof toward the window stool 21. In other words any water which might run down either side of the ventilator is retained to the outside of the weather strip H, with any water collecting between the weather strip and the ventilator being immediately drained to the outside of the window through the water passages in the bottom of the ventilator. As a result any water running .down either the inner or outer face of the vventilator full intended scope of this invention as defined by the appended claim.

I claim:

In ventilator means for a` -window structure with a movable sash having a groove in the bottom rail thereof and said window structure having an upstanding tongue on the sill therefor adapted to fit into the groove to provide a weather seal when the window sash is closed, a ventilator for fitting between the sash and sill when the window is open comprising telescoping plates having ventilating openings therethrough, said ventilator being extensible across said window opening and having a top edge portion receivable in the window sash groove to retainthe ventilator at the top and close the windowl opening, said plates each having an inturned channel-like portion at the bottom thereof adapted together to be positioned to the outside of the upstanding tongue, and said channellike portions having 'a drain opening therein opening to the outside of the plates to drain away from said channel-like portion any water collecting therein from the inside of the ventilator.
