April 1521930. Q R, JOHNSON 1,754,559
WINDOW VENTILATOR Filed Sept. 30, 1927 @fj/1"@ a l.
Inventor Patented Apr. 15, 1930 UNITED STATES' PATENT 'oFF-ica CLAUDE n. Jamison, or amori, oxLAnonA, Assreivon 'ro 'ma cLAUDEsoN LA aoBA- from? me., or wimrnre'ron, DELAWARE i WINDOW VENTILATOB Application led September 80, 1927. Serial No. 223,075.
This invention relates to newand useful mprovements in ventilators and aims to proin windows and that will automatically`conorwindstorm. Furthermore, the ventilator is trol the passage of air into the room, the device being normally operable to open position under normal atmos heric conditions but to automatically close uring an unusal breeze of such construction as to prevent the passage of rain, water, dirt or the like through the window but at the same time to permit the priper passage of air therethrough.
urthermore, the invention aims to provide a ventilator that is of adjustable length so that the same may be arranged within various sized window frames and that may be rigidly secured therein by lowering the sash thereon.
However, if desired, theventilator may be arranged within the upper end of the frame and there secured by forcing the upper sash against the bottom edge thereof.
In-the drawing wherein like reference characters correspond to like parts throughout the various views Figure 1 is a fragmentary elevation of a 4window frame within which is disclosed a sliding sash, while arranged within the frame 3o beneath the sash ismy improved ventilator,
Figure 2 is a to plan view of the ventilator,
Figure 3 is a etail vertical section taken at the point 3--3 of Figure 2, and,
Figure 4 is a section through one of the side frame bars of the ventilator lbetween which are pivotally supported the shutter units of the ventilator.
Now having particular reference to the drawin s, my novel ventilator consists of a pair o similarly constructed vertical end frame members 5-5 preferably of sheet4 metal. These frame members are inter-connected at their upper and lower ends by adjustable length bars 6-6 which bars consist of telescopical sections as clearly indicated in Figures 1 and 3. V
The invention further consists of a plu- .rality of horizontally arran ed shutter members. 7 each of which is of inverted V-shape in cross section and each -of which comprises a pair of sections having sliding con nection with each other so that the length thereof may be adjusted simultaneously with the adjustment of the ventilator frame. The
lower edges of the outermost sections of these shutters are crimped over the lower edges of the innermost sections as at 8 to prevent the movement of the sections in any direction except longitudinally. 4
At the apex of these shutters the same are equipped at their ends with longitudinally extending pins 9 for detachable engagement within transverse slots 10 at the innerY sides of the vertical frame bars 5 5. Obviously, this connection between the shutters and the vertical frame members will permit of the shutters being removed from the frame whenever desired.
As clearly disclosed in Figure 3, the shutter members are arranged onel above the other and in spaced relation. v The length of the side walls thereof being such that the lower edges will engage the side walls of the next under shutter to swing closed in either direction for completely closing the passage through the .ventilato-r. Furthermore, by reason of the pivotal connection between the shutters and the frame, said shutters are free to swing in reverse directions so that the shutters will close under heavy drafts. Furthermore, by reason of' the particular character of the shutter members rain and snow will be prevented from passing through the ventilator and entering the room.
It is of course obvious from a consideration of Figure 1 that the frame after being adjusted to a desired Alen th is arranged within the window frame preferably beneath the .sliding sash B after which the sash is lowered'upon the top of the frameto rigidly securepthfe same within the window. However, if desired, the ventilator may be arranged directly beneath the upper end of l efiicient window ventilator that is well adapted for all of the pur oses heretofore designated and even thong I have herein shown and described the invention as con- 5 sisting of certain detail structural elements, it is nevertheless to be vunderstood that some changes may be made therein without departin from the spirit and scope of the ap en ed claim.
aving thus described my invention, what I claim as new is In a window ventilator of the character described, apair of U-shaped le members, the leg portions of one member being hollowand a apted to receive the leg portions of the complementary member in telescopic relation, a plurality of detachable pivotal shutter units arranged horizontally within said frame, said shutter units each consistin of a pair of slidable sections, said sections in substantially V-shaped in cross section an each having one of its ends pivotally connected to one end of the frame, said sections being provided with its edge portion bent inwardly in'spaced relation to itself, and the other section being slidably engaged at its free end portion within the inwardly bent edge portion of thelcomplementary section, whereby the frame shutter unit may be extended. In testimony whereof I aix my signature.
CLAUDE R. JOHNSON.
