Application nled'anuary 7, 1924. Seria1`lto.-684,836. y .j

To aZZwwm t may concern: 'i j Be it known that I, THEononE S. DEN nsHA, a citizen of the United States, residingat New Bedford, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Ventilatore, of which the following is a specification. y

The present invention relates to ventilating devices, and more particularly to a combined ventilator and screen intended for use Where substantially continuous ventilation is desired. j

An object of the invention is to provide a ventilator which serves to exclude insects, and which cannot be readily removed by one attempting to obtain Iadmission through the window to which the same is applied.

A further object of the invention 1s to provide a ventilator which may be conveniently adjusted in order to regulate the volume and the direction of the draft permitted to enter aroom, and which, is sightly and durable in construction.

Referring to the accompanying drawings, wherein there is disclosed a preferred embodiment of the invention,

Figure 1 is an elevational view of the ventilator installed, the same being viewed from the interior of a room. f-

Figure 2 is a top plan view,

Figure 3 is a vertical sectionfon theine 3 3 of Figure 1, and j Figure 4 is a section on the line 4 4 of Figure 1, looking in the direction of the arrows. A

In the drawings, 10 indicates a window frame having an inner sill 11 and an outer sill 12, and serving to inclose a lowersash 13 vertically movable between guides or stops 14, 15 positioned at each side 'of the sash.

The ventilator, which is positionedfbeneath the partially raised lower sash, comprises a rectangular frame, including upper and lower horizontal parts or strips 16 and connecting end strips 17. The strips 16 have a pluralityvof sockets serving toreceive the pintles 18 of a series o f slats 19, which are adjustable about the pintles as vertical axes. A connecting rod 20 is secured yto the individual slats, as by means of eyes 21, upon the slats and rod, respectively, and as will be understood, longitudinal adjustment of the rod serves to open and close the slats,

` ing of the ventilator at all times.

thereby permitting regulation ofV the draft admitted lthrough the ventilator. The end strips 17'ofth`e frame have'sockets 23 serving to Areceive the ends of the rod ,20 when the spaces between the slats'l are closed;

The frameis of rsuttit'nientwidth to project between the

sash guides

14, 15 and ordiynarily is installedby removal of one of the inner' stopsy 14, which :is replaced after the frame is tted into position. It will be noted that the frame pieces are of substantially light material, which does not entirely fill the space between the sash guides. The frame is provided with a binding comprising end pieces 25, one of the same being shown in Figure 4, which are of substantially the ywidth of the sash groove between the guides, and thus insure a rigid position- Moreover, in order to further guard against removal of the ventilator, and to protect the same, a top ybinding strip 26 yis provided,

the same being of substantially greater width than the frame and having its inner surface Hush withy the inner face of the frame. Ther top piece projects beyond the outer face of theframe, and at its ends is formed with notches 27, which receive the outer guides 15.' This piece serves as an abutment forthe windowvsash and protects a 'screen y27, which is positioned upon the outside of the ventilator. A spacing. strip 28 serves to space the screen from the-slats, and upon ythe strip the margin of the screen is secured by means of a molding 29.

It will be observed that vthe ventilator is very simple in construction, and the arrangement of the parts above described affords a durable structure whichy cannot be readily removed by one seeking admission to a room through the window to which the ventilator is applied.

The top face of the binding v,serves to support the window sash. In order to positively exclude rain vand moisture, a sealing strip 30, substantially L-shaped in cross section, is secured to the top piece and its upwardly projecting portion overlaps the sash. This sealing stripmay be dispensed with if desired, but ordinarily it will be found to be a valuable adjunct.

When the ventilator is installed, the screen 27- serves to exclude insects, and by adjusting the slats, the draft may bey directed toward the right or left, as may be desirable. Moreover, a draft may be practically eliminated by closingv the slats. The entire structure is extremely durable, and

vpractically the only part which will at any frame of substantially greater width than said frame and including a top piece having end portions adapted to extend between said sash gudesysaidftop piece having one edge Hush with the inner surface of the l:E1-ame and on the other side of the latter extending outwardly over said screen and stripz the ends of said toppece on the last mentioned side of the frame having notches serving to receivethe outer sash guides,l and a sealingv flange on said top piece extending upwardly and adapted to overlap the sash when the latter rests upon the said top piece.

Intestimony whereof I have hereunto set. my hand.'
