. This invention relates to window constructions and has as one of its Objects to simplify, render more efficient and improve generally equipment of this type.
Another object of this invention'is t I proing therein closed by a movable sash and a ventilator and having a bar forming a stop for the sash and a support for the ventilator.
Another object of this invention is to pro vide an improved ventilator so constructed as to form a dead air pocket and having a louver opening in the outside wall thereof arranged to permit any moisture entering the air pocket to drain out of the latter.
A further object of the present invention is to provide a ventilator of the above type having means therein for preventing air, moisture or dust from passing directly through the ventilator.
A still further object of this invention resides in the provision of a ventilator having adjustable means for controlling the quantity of air passing therethrough together with means for screening the'air.
Other objects of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, where- 1n:
Figure 1 is a front elevational view of a window having a frame constructed in accordance with this invention.
Figure 2 is a sectional view taken on the plane indicated by the line 2-2 of Figure 4.
Figure 3 is a sectional view taken on the plane indicated by the line 33 of Figure 4, and
Figure 4 is a fragmentary rear elevational view of the construction shown in Figure 1.
Referring now to the drawing, it will be noted that there is illustrated in Figure 1 a window 10 comprising a frame 11 having top and bottom bars 12 and 13, respectively, normally secured in proper assembled relation to each other by means of the side bars or stiles 14c. The frame 11 is further provided with an opening therein normally closed by a swinging'sash 15 hingedly connected along one edge to one of the frame members aforesaid in any desirable manner. I I
The swinging sash 15 may be of any suitable construction but is preferably provided with a frame 16 having the bottom bar 17 thereof spaced above the bottom bar 13 of the frame and operable when in closed position to engage the bar 18 extending substantially parallel to the bar 13 and spaced a. suitable distance above the same. The bar 18 in the present instance has the end portions thereof secured in any suitable manner to the stiles 14 and cooperates with the lower end portions 19 of the stiles and bottom bar 13 to define a space 19 of sufiicient area to re ceive the sill ventilator unit 20. The opposite end portions of the ventilator unit 20 are preferably secured to the end portions 19 of the stiles while the upper and lower edge portions of the sill ventilator are preferably secured to the bars 18 and 13, respectively. The above construction is such as to permit locating the ventilator 2O entirely within the boundaries of the window frame 11 so as to form a unitary construction therewith,
with the result that the window frame 11,
As shown n Figure 1, the ventilator is 10- cated within the frame below the swinging sash and preferably extends for a greater width than'any one of the separate window panes 15. This arrangement, in addition to possessing the foregoing advantages, also provides a neat and compact construction since the ventilator is located substantially transversely within the window frame While any suitable construction of ventilator may be utilized in the above assembly, I- have illustrated in Figure 2 a ventilator construction found satisfactory for this purpose. The ventilator 20 is formed of a pair of laterally spaced inner and outer plates 21 and 22, respectively, of sufficient dimension to fit within thespace 19 and cooperating to form a dead air pocket 20. As shown particularly in Figure 2, the outer plate 22 is provided with struck-out portions 23 forminga series of downwardly opening louvers 24 permitting the passage of air through the plate 22. The arrangement is such that the struck-out portions 23 of the plate 21 function as shields for the open-- ings 24 to prevent water or other foreign matter from entering the openings 24. The inner plate 21 on the other hand is formed with an elongated opening 25 closed by a plate 26 having the marginal portions there of secured to the inner plate 21 by the fast 24 open into the ventilator adjacent the lower edge of the latter and are provided with inclined downwardly and outwardly walls 37 from the surface 36 permitting any water or the like deposited upon the surface 36 to drain out of the ventilator into the atmosphere.
As shown in Figures 2 and 3, the sill ventilator is secured to the end portions 19 of the stiles and to the bars 13 and 18 by putty or similar plastic material permitting the ventilator to be readily assembled within the frame. It should be understood, however,
ener elements 27. The plate 26 is provided that any suitable means may be utilized for with a series of slots 28 registering with the opening 25 and arranged in communication with the louvers 24 to receive the air flowing through the latter. In order to control the flow of air through the ventilator 20, I provide a slidable closure member 29 having the longitudinal edges thereof slidably support ed by the guides 30 secured to the outer sur-- face of the plate 26 and extending longitudinally thereof. The slide 29 is formed with a series of slots 31 therein corresponding in dimension to the slots 28 and adapted to register with the latter to permit the flow of air through the ventilator. For adjusting the plate 29 to control the passage of air through the ventilator, I provide suitable operating member 32 secured to the slide 29 intermediate the ends thereof and projecting through a longitudinally extending slot 33 formed in the plate 29. The arrangement is such that the quantity of air flowing through the ventilator may be accurately regulated by manipulating the operating member 32 to slide the plate 29. If desired, suitable screening 35 may be secured within the venlator to prevent insects from entering the openings 28. The screening is preferably carried by the guides 30 and the construction is such that the screen closure member and cover plate 26 may be readily removed as a unit by merely detaching the elements 27 In order to prevent the air flowing through the louvers 24 from passing directly through the slots 28 and 31, I provide a baflle plate 34 within the space between the inner and outer plates 21 and 22. As shown in Figures 1 and 2, the battle is preferably secured to the outer plate 22 in rear of the louvers 24 and is provided at the lower end thereof with a projection 35 engaging the outer surface of the plate 26 adjacent the lower edge thereof. The arrangement is such as to compel the air flowing through the louvers 24 to pass upwardly beyond the upper edge of the baffle 34 prior to entering the openings 28 and 30. lVith the above construction any outer impurities entering the louvers 24 with the air will be deposited upon the lower inner surface 36 of the ventilator. In this connection it is to be noted that the lower set of openings securing the ventilator in place without departing from the spirit and scope of this invention.
lVhat I claim as my invention is:
A ventilator comprising spaced inner and outer walls cooperating to form an air:
pocket and having communicating openings therein, a screen interposed between the said openings, a slide for controlling the quantity of air passing through the opening in the inner wall, a cover plate for said last-mentioned opening carrying said slide and screen, and means detachably securing said cover plate to the inner wall whereby said cover plate, slide and screen may be removed from the inner wall as a unit.
In testimony whereof I affix my signature.
