wIivDow VENTILATOR.

Application filed January 6, 1923. Serial No. 611 059.

This invention relates to ventilators and has particular reference to those ventilators which are removable.

The primary object of my invention is the provision of an improved ventilator having a flexible body member including a frame which is foldable so that the flexible body portion will be in a plane and the frame members will lie together and substantially in parallel lines.

Another object of my invention is the provision of an improved ventilator having a foldable frame at the top which, when in place, will hold its flexible body portion taut at its front and sides.

Still another object of my invention is the provision of a folding ventilator which is attached to a roller and provided with a folding frame, the flexible body portion and frame being so constructed that the flexible body may be folded so that all the parts will lie flat together and the frame parts will have their axes parallel, and close together, whereby the ventilator may be rolled on the roller similar to the manner of rolling a shade.

Still another and further object of my in vention is the provision of a ventilator which can be folded and rolled and which is provided with a mosquito bar which Wlll prethrough the ventilator and which can be. folded and rolled with the ventilator.

ferred embodiment of my invention is illustrated, r

10 designates the window frame, to which the ventilator is shown attached. A spring roller 12 is provided with brackets 13 which are mounted on the window frame. Attached to the roller is a strip 14; of flexible material which is rolled thereon. This strip 14: may be of varied length depending upon how much vertical adjustment is desired. Above the part 14 is a flexible front portion 15-which, when the ventilator is in place, extends away from the window to conduct the form of my air toward or away from the window as the case may be- At the sides of the part 15 are two angular pieces 16, 17 of flexible material which occupy the space between the sides of the part 15 and the window frame. At the top of the ventilator and the edge of the parts 15, 16, 17 is a frame 18 which has hinges located at the points 19 and 20 where the upper edges of the i parts 16 and 17 meet the ends of the upper Referring to the drawlng wherein a preedge of the part 15. The hinges at the points 19, 20 are so arranged and the parts 16 and 17 so shaped that when the parts 16 and 17 and the parts of the frame 18 at their upper edges arefolded inward on the part 15, the frame parts at the upper edges of the parts 16 and 17 will lie adjacent the frame part at the upper edge of the part 15. This construction is to facilitate the rolling of the curtain upon the roller 12 in a manner to be described. Atthe inner or window ends of the frame and adjacent the upper corners of the parts 16 p and 17 are placed suitable securing means for holding the ventilator in place. Figure 3 shows such a means. The hook 21 is rigid with the end of the frame and extends outward from the frame and then downward substantially parallel with the window frame edge of the side parts 16 and 17. A socket 22 is provided for attachment to the window frame to receive the hook 21. It is to be noted that, because of the shape of the hook 21 and its receiving socket 22, the portion 15 of the ventilator will be held taut and in its proper place. Two or more pairs of sockets 22 may he provided .as shownYinFigure 1, to

provide for adjusting the ventilator at different heights. I

Referring now particularly to Figures 4 and 5, 30 designates a mosquito bar which is shown attached to the ventilator "for preventing flies and mosquitoes ifrom;entering the room through the ventilator. At the upper edge of theport-ion 15'..ofthe ventilator are provided hinges-3l for securingithe mosquito ibtll' to the ventilator. ,These hinges 31 are providedwith loops 32 whiclrreceive the wire {33 which constitutes a partof the "hinge and is received by the fold 34: at the edge of the mosquito ha r edge .as shown i-nrFigure 6. This fold 34 may be of felt or other suitable -material and-receives and holds the edge of the mosquito bar.

The mosquito bar is bound also at the sides at 35,36 with, a flexihle material asfelt and :has a wider binding or flap 37 adjacent the windowfor making tight the bar at this point. If desired, hooks 38 and eyes39, in the.sideparts;16, -l7, may beprovided to hold .the parts 16, 17 against the window frame.

-Referring now particularly to :Figures 8, .9.,;lLOiand 11,14 designates the strip of the ven- .tilator attached to-the roller as shown in-Figs. g1 and 2. The ventilator holding 110x 40 is intended'to be used'inplaeeof-brackets-13 of :Figs.1,:2 and l' vvhere desired. This ventilator holder box 40 is held in plaoeeonwthe window sill by the screws 41. .At theleft end of box .40, is :a hole for the .--round pintle of {the roller. This left endis shown :as integral with the body ofthebox 40. Atthe-right-end .of the box is a door ;42:hi-nged at This wdoor is provided with an" opening for the-flat nonerevolving shaft ofthe springroller, as shownyatr lim-Fig. 10. On thetop ofithe -=,box lOisacover 45 'which-is hinged to "the boxes-at 46. The outer-edge OfitllG cover 45 comes 'short of covering the opening just a sufiicie'nt distance'to permit of the portion 14 of the ventilator passing through :thereat, whenthe-cover is closed. In this :Way,*the cover l lzholds the lower portion '14 of the ventilator close to the Window frame and prerents the admissionof flies and n'iosquitoos underneath the-roller.

Having described my invention, what I claim is 1. A ventilator fo'r windows eompl ising a flexible body portion'comprising a trontand sides and a foldable frame for and secured to the respectiveparts of the body portion, the frame portions heing foldable in such a manner that-their axes are-adjacent and paralll and so correlated to the body portion that when folded will bring the'portions of 'bodyf p ortion flat and adj acenteaclr other and means at the inner ends of the side frame portions for supporting the frame "from the window casingwithholding-the body por- 1 tion taut.-

2. A ventilator for windowscomprising a taehed to theroller for guiding the air, an insect bar secured to "the body portion and forming a closure, against'insects, for the opening of the ventilator; the sides of the ventilator and the bar being "ifol-tla'ble on the front portion whereby the Whole may be rolled upon the roller. 4. A ventilator for Windmvs comprising a roller, front and side portions attached to the 5 roller for guiding the air, an insect bar, the bar forming a closure, against insects, for the opening of the ventilator, aholder for the ventilator roller, having an enclosure for receiving the ventilator when rolled and for preventing the passage of insects therebelow 10 when the ventilator is in operative position.
