Patented Nov. 14, 1950 2,529,792 STORM SASH VENTILATOR AND nErLEoroR William Wityaz and Frank Kendra, hicago, lll. Application February 14, 1947, Serial No. 728,454

2 Claims.

This invention relates to a novel construction of ventilator and deflector for use with storm sashes and to provide means for permitting sufficient air through a storm sash to afiord adequate ventilation and without opening the sash or removing it from its normal position within the window frame.

More particularly, it is an object of the invention to provide a ventilator and deflector capable of being readily applied to conventional storm sashes and which is of extremely simple construction involving a minimum of moving parts which may be applied to and used in conjunction with a storm sash with only a slight modification of the storm sash.

vStill another object of the invention is to provide a device of the aforedescribed character which will efiectively deflect the air entering through the storm sash for eliminating a direct draft from the air when it is admitted through the conventional window sash and into a room or other enclosure.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, illustrating a preferred embodiment thereof, and wherein:

Figure 1 is an elevational view, partly in vertical section looking toward a portion of the lower part of a storm sash and showing the ventilator and deflector mounted on the inner side thereof;

7 Figure 2 is a horizontal sectional View taken substantially along a plane as indicated by the line 2-2 of Figure 1;

Figure 3 is a vertical sectional view taken sub-, stantially along a plane as indicated by the line 3-3 of Figure 1;

Figure 4 is a view similar to Figure 3 but showing the ventilator in an open position and the draft deflector in an operative position;

Figure 5 is a vertical sectional view taken substantially along a plane as indicated by the line 55 of Figure 4;

Figure 6 is a plan view of one end of the deflector and closure; and

Figure '7 is an enlarged horizontal sectional view taken substantially along a plane as indicated by the line 1'| of Figure 3.

' Referring more specifically to the drawings, the ventilator and deflector in its entirety is designated generally 8 and for the purpose of illustrating the application and use thereof, the numeral 9 designates a portion of a window sill forming a part of a window frame, not shown, containing sliding sashes, a portion of the lower 2 sash 10 of which is illustrated in Figures 3 and 4. A storm window, a portion of which is illustrated and designated generally I2 is adapted to be mounted'in any suitable manner in the window frame of which the sill 9 forms a part and has a bottom rail or bar [3 which rests upon the sill 9. As clearly illustrated in Figures 3 and 4, the storm window I2 is spaced outwardly a considerable distance from the lower sash ID as is conventional in the mounting of storm windows and the ventilator and deflector 8 is adapted to be disposed in said space and secured to the inner side of the.

lower, rail or bar [3 and when thus disposed is spaced a considerable distance outwardly with respect to the sash l0. I The ventilator and deflector 8 includes a housing, designated generally [4 comprising an outer wall [5 which is disposed substantially parallel to the rail l3 and provided with inturned portions at the endsthereof forming side walls l6 which extend towardthe rail l 3 and which terminate in Qut-turnedflanges, llwhich abut against the inner side of the rail- [3 and are secured thereto by suitable driven fastenings IS. The outer wall [5 is provided with an inturnedlip or flange l9 at its bottom edge which is disposed in substantially the same plane as the bottom edges of the side walls It. As best seen in Figures 3 and 4, the upper surface of the sill 9 on which the storm sash rail l3 rests slopes outwardly and downwardly and the housing I4 is secured to said rail so that the rounded corner formed by the juncture of the wall l5 and the lip I9 will rest on the upper surface of the sash 9 and will form the only portion of the housing [4 in engagement therewith.

The only modification of the storm sash which is required for use of the ventilator and deflector 8 is the provision of one or a plurality of openings 29 therein and which are located between the walls I6 in the bottom rail I3; three openings being shown in Figure 2, although it will be readily apparent that agreater or less number of openings could be proyided or, if desired, a single elongated opening could be employed.

Each of the side walls I6 is provided with two longitudinally spaced rollers 2| and 22 which are disposed in substantially the same plane and which'are journaled on pins or rivets 23 which are anchored in said side walls l6. As best illusopening outwardly of its shank end for receiving a threaded stem 28 which is removably mounted therein and provided with a head 29 at the outer end thereof for retaining the roller 2| or 22 in rotatable engagement with the stem 24.

The rollers 2| are disposed in longitudinal alignment and adjacent the inner side of the rail l3 and the rollers 22 are similarly aligned and disposed adjacent the wall l5 and spaced approximately the same distance therefrom as the rollers 2| are spaced from said rail l3. A combination valve and deflector plate 30 has a lower portion which is adapted to be inserted between the rollers 2| and the inner side of. the rail |3 or between the rollers 22 and the inner side of the wall l5. When in the first mentioned position, said lower portion of the plate, 30 will be disposed between the rollers 2| and the inner side of the rail l3 and retained by said rollers 2| in tight engagement with the rail |3 so that the ventopenings of the'rail will be effectively closed and sealed by the lower portion 3| of the plate which thus forms a valve or closure. The upper portion 32 of the plate 30 overlies the ends of the lower portion 3| to provide the downwardly facing shoulders 33 which rest upon the uppe edges of the wall Hz for supporting the bottom edge of the plate out of engagement with the sill 9. The plate portion 32 terminates at itsupper edge in an arcuate portion 34 which is disposed to curve inwardly and away from the storm sash l2 when the'plate 30 is in its aforedescribedposition as illustrated in'Figure 3. To position the plate 30 to function as a deflector, said plate is drawn upwardly and thereby disengaged from the rollers 2|, rotated a half turn and inserted between the rollers 22 and the wall Hi and with the lowerportion 3l-thereof disposed in the housing M, as in its previously described position. With the closure portion 3| disposed against the inner side of the wall l5, as illustrated in-Figure 4, it will be readily apparent that said closureportion will be spaced from the openings 20 so that air maypass freely through said openings and the air will be deflected upwardly bythe plate 30 and back toward the storm sash f2, above thebottom rail |3'by' the flared upper edge 34; which is disposedto extend toward the storm sash, due to the rotation of the plate 30. It will thus be readilyapparentthat the air entering the openings 20 will substantially follow the path as indicated by the'arrows in Figure 4 and accordingly willenter the opening formed between the sill 9 and the raised lower sash I0 without creating a draft.

The rollers 22 are preferably formed of rubber or other relatively resilient material for yieldably retaining the plate 30 in its position of Figure 3 against the storm sash bar |3 for effectively closing the vent openings'20.

Various modifications and changes are contemplated and may obviously beresorted to, without departing from the spirit or scope of the invention as hereinafte defined by the appended claims.

We claim as our invention:

1. In combination with a window sash having a bottom rail provided with at least one vent opening, a housing secured to the inner side of said sash rail and with which said vent opening communicates at its inner end, said housing having an inner side wall spaced from said sash rail and an open top, a combination closure and defiector plate insertable through said open top of the housing, a first means connected to and disposed in said housing adjacent the sash rail to engage and press a portion of the plate against the inner side of the sash rail for closing said vent opening, a second means connected to and disposed in said housing adjacent said inner side wall to engage and hold said plate portion against the inner side wall and out of engagement with the sash rail for admitting air to the housing through the vent opening, and said plate having a deflector portion extending upwardly from the housing and curved toward the sash, when the plate is disposed against said inner side wall, for deflecting the air rising from the housing back toward the window sash, said housing having end walls disposed substantially perpendicular to said sash rail and inner side wall, said first means and second means each comprising a pair of rollers journaled in the housing on said end walls.
