WINDOW VENTILATOR Application filed February 4, 1930.

The presentinvention relates to improvements in window ventilators of the type which v is adapted for co-operation with the ordinary vertically sliding lower sash of customary window construction.

The main object of the invention is to provide a ventilator of the type mentioned which may be readily adjusted to fit windows of any width within reasonable limits, and the end members of which may be set at varying angles according to the requirements.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described,

pointed out in the appended claims and illustrated in the accompanying drawings, it

being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view showing the improved ventilator positioned on a window; Fig. 2 is a section. taken in plane 22 of Fig.

1, on a larger scale; Fig. 3 is a side elevation of one of the end members of the device; Fig.

l is a top plan view of the device shown in Fig. 3; Fig. 5 is a perspective view, on a larger scale, of an extension element associated with a deflecting frame of the ventilator; and Fig. 6 is a perspective view, also on a larger scale, of an extension element associated with the screen element of the improved ventilator. In the drawings, the numeral 10 indicates the lower sash of a window, slidable in a window casing 11. The ventilator, which is to be secured to the said casing consists of two substantially triangular, preferably, sheet metal end members or brackets 12, a deflecting frame 13 and a screen frame 14.

Each of the end members is in substantially the form of a right-angled triangle, although this is not essential, and consists of three plates 15, 16 and 17. All of these plates Serial No. 425,781.

are substantially triangular, the plate 16 being pivoted at 18 adjacent its lower apex to the plate 15, adjacent the lower apex of the latter. The plate 17 is pivoted at 19 to the plate 16 adjacent the outer inclined edge 20 of the plate 16. The plate 16 overlaps the plate 15, and the plate 17 overlaps both plates 15 and 16, as clearly shown in Figs. 2 and 3 of the drawings. The plate 15 is attached to the window casing immediately above the sill 11 thereof by screws 21, or the like. By swinging the plate 16 around its pivot 18 on the plate 15, the width of the end member of the ventilator may be varied according to the requirements. When so adj usted, the plate 17 must, obviously, be swung around the pivot 19 to bring its free edge 22 as near as possible to the inner face of the lower rail of the lower window sash, when the latter is raised to permit ventilation of the room. The end members of the ventilator project into the room. Each plate 16 is provided adjacent its inclined edge 20 with two spaced flanges 23, forming a channel. These channels arebrought into alignment and into the same may be slid the deflecting frame 13. The deflecting frame is made of wood or the like and includes two stiles 24, connected by an upper rail 25 and a lower rail 26, and holds one or more glass panes 27. Over each stile is slid a preferably metallic casing 28, shown in detail in Fig. 5 of the drawings. These casings form extension pieces for varying the length of the deflecting frame, to suit different widths of window casings. The extension casings may be secured to the stiles of the deflecting frame in any suitable manner, for instance by nails 29 which are driven through holes 30 in the casings into the respective stiles. In sliding the deflecting frame into the channels in the plates 16, obviously the outer ends of the casings are seated in the said channels. To the lower rail 26 of the deflecting frame is attached a resilient strip 31 of felt or rubber, to contact with the sill of the window frame. Similarly are attached to the lower faces of the extension casings 28 resilient strips 32, which rest on the window sill.

The deflecting frame extends across the entire width of the window opening and its upper rail projects above the flanges 23. To the deflecting frame is attached by hinges 33 the screen frame 14, which extends in the position shown in Fig. 2 of the drawings from the inclined edges of the end members of the ventilator horizontally toward the lower window sash, it being adapted to rest upon the inwardly bent flanges 34 on the plates 17. The screen frame is covered with two spaced finemeshed wire fabrics 35, or the like, said fabrics being held upon the frame in any suitable manner, for instance by molding strips 36. Upon the transverse end members 37 of the screen frame are mounted, preferably, metallic extension casings 38, secured thereto, for instance, by nails 39, which are driven through holes 40 in the casings into the respective end members 37. The rail 41 of the 4 screen frame, which is disposed adjacent the window sash, carries a resilient strip 42 of felt or rubber, said strip being adapted to abut against the lower rail of the window sash, when the latter is raised to permit ventilation of the room. The extension casings 38 carry each a resilient strip 43 in alignment with the strip 42.

The strips 31, 42 and 43 serve, obviously, to make an air-tight closure.

The operation of this device is as follows: hen the device is in position on a window frame, as shown in Figs. 1 and 2 of the drawings, the lower window sash is raised until the lower rail thereof is in abutment with the strips 42 and 43 on the screen frame. Air entering through the fabrics 35 passes into the room through the window aperture and is directed upwardly, thus avoiding direct draft. The fabrics screen the air, permitting thorough ventilation without the accompanying annoyance of dust and insects.

In mounting the ventilator on a window frame, first the two end members 12 are secured to the said frame and the plates thereof set to suit the requirements. The extension members 28 and 38 are thereupon fixed to the deflecting and screen frames, respectively, they being set on the stiles and transverse frame members, respectively, of the said de flecting and screen frames a distance to ex tend throughout the width of the window openlng.

What I claim is 1. The combination with a window frame and a vertically slidable sash therein, of a pair of ventilator end frames secured to the vertical members of said window frame immediately above the sill portion thereof so as to project into the room, said end frames having formed thereon a pair of channels in alignment with one another, a deflecting frame including end stiles, an upper and a loyer rail, an extension casing fitted to each of said stiles and secured thereto, said deflecting frame and the extension casings thereon being slidable in said channels and resting upon said sill portion, the upper rail of said deflecting frame being spaced from said sash, and a screen frame hinged to said upper rail including transverse end members, and an extension casing fixed to each of said transverse end members, said screen frame being adapted to rest on said end members.

2. The combination according to claim 1, comprising a flange formed on each of said end members on which extension casings of said screen frame are adapted to rest.

3. The combination according to claim 1, comprising resilient strips on the lower rail of said deflecting frame and on the lower faces of the extension casings thereon, adapted to contact with said sill.

4. The combination according to claim 1, comprising resilient strips on said screen frame and on the extension members thereon, adapted to contact with the lower rail of said sash.

5. The combination according to claim 1, each of said end members consisting of a plurality of overlapping plate sections permitting adjustment of the end member both as to width and height.

6. A window ventilator end member consisting of a plurality of overlapping plate sections, and pivots uniting said sections so as to permit adjustment of the end member both as to width and height.

Signed at New York city, in the county of New York, and State of New York, this 18th day of January, A. D. 1930.

EUGENE J. NEY.
