WINDOW Vannini/iron.

Application filed November 27, 1926. Serial lNo 151,120. A

. ment so as to be placed withinI a window acter, which is extremely simple in constlriic- I tion, thoroughly reliable and eilicient in its frame to permitthe window sash. to be brought in engagement therewith, lwhereby ventilation may be had through the window,

.without liability of the ingress of sleet, rain7 or snow lto the interior of the enclosure having the window, the adiustment `of the ventilator permitting the same tobe adaptable for .various sizes of window frames.

Another object ofthein'vention is the .provision of a ventilator of this character, wherein the saine can be placed .within an opening constituted' bythe partial raising of the window sash in the -frame and will. shield such opening to constitute a deflectorv for a draft of air passing through the opening 'from without to the interior 4of the building.

A ,nu-chef Object. of the invention is the provision of a ventilator of this character, wherein the, entirestructure is made from met-al and is united together in the parts thereof ina novel mannen-so that such parts will vbe'firm and secure and the said ventilator capable of varyingadjustment to. adapt Vthe same `to different sizes of thefwndow frames. i l' f A still further object ofthe inventionis the provision of a ventilatorof this charpurpose,v strong, durable, readily andf easily Yapplied to and removed from a Vwindow frame and inexpensive to manufacture.

struction, combination and arrangement of' .part-s, as will be hereinafter more fully described, in detail, illustrated in the accompanying drawing, showing the preferred em-v bodiment of the niveiition and pointed out v in the claims-hereunto appended.

Referring to ther drawing 'in fdetail,` A

designates generally a portion of a window' frame, which is of ther conventionaltype.y

and B the lower sasln slidably :mountedr vwithin the frame lin the usualY orfcustoinary mannerbetween 'the guide-strips 10and11,

respectively, carried by each side of the window framei between its sill 12 andthe head of said-frame, the headybeing noti"V sliowinv vf ll-id'apted'to be reinovablyand adjustably f vh'eldgwitliin the windowrframe is the ventilator constituting the present inventioin' which willv be, hereinafter more fiillyf described in detail.v L 'y i.

Thejventilator comprises apai'r fof telefscopically connected extensiblev sections 13 and'l 14E",v respectively, each being formed withV yso a' lower bottom iplate p15-and anupperor top head plate 167 both beingformed from vlith these and'y other objects in view,v the invention consists in the..features of con-v sheet metal. rl`he outer ends of these sections V13 and 14 have the.. lowerv and upper plates 15 and 16'are spacedapart 'and have" ticulated or-wiremesh fabric 19.1 eachbeing engaged at its inner end in afolded-over end strip 2O and at the opposite longitudinal :10o arranged tocovorgsuch space screens orre-v edges by folded-over longitudinally `extending border strips 21, while'the, `outer end .edge of the fabric 19 is foldedin with the outer end strip 17, connecting the plates' and 16 together. The strips 20 and 21 are fastened to the plates v15 and 16 Vthrough the medium of splitrivets 22, While linkedito the outer strip 17 of each extensible section and riveted to the fabric 19 is a reinforcing strip 23. The fabrics 19 constitute the ven1 t-ilatingpanels of the sections 13V and 14 asl will be apparent.

outer spaces of the sections 13 'and-141 so as nottointeri'ere with the extension of the` sections when. telesco'pically connected in relation to each other. Thetop plates 16y of tlresec'tionsv 13 land 14 are extended to provide angularly disposed awning-like Vshields 24 and v25,"respectively,'having the straight free end portions 26 disposed parallel with the plane of the sections 13 vand but spaced 'a distance therefrom and held 1n such spaced relation 'by-the braces 27 connected thereto and to 'the sections 13 and- 14, re-

. spectively. y

The section 14' has its bottom plate 15` and the Canopy exteitlsion'25y bent on themselves to provide the guide flanges 28 and 29,1'espectively, to provide rufnWays for the edges of 'the extensions of the bottom plates 15 and the extensions 24 "of the other section 13.

n and in' this' manner these sections 1.3 and yau 14 4are slidably connected with a unitary structure. I

The ' canopy extensions 24 and 25 overhang Ventilating *panels 19 of the sections 13 fand 14 and the canpy extensions terminate 4a distance above lorffrom the free edges `of vtil-1e bottom iplates 15 of the sections 13 and or'm an air way as indicated by the arrows in Figures 1 and 6 of the drawing for ventilatirg purposes Jto admit Vair y from Without `Will be positioned either as shown in Fig? lure l or vFigure of the drawing. When positioned ving the `ventilator will shield sleet, rain, or

` "snow fand prevent 'the same from-entering through the opening in the window, when the enclosure to the interior thereof, y i

1 VInt-he use of the ventilator the sections 13 and 14 are extended relative to `eachother so 'that 'their outer ends will engagebetween the guide strips 10 and 11 of thewindow frame A and the canopy extensions 24 and asshoW-n in 'Figure 1 Vof the drawvthe sash B is brought against "the same at .Y VKtheftop thereof. When the ventilator is upset `and reversedwhen engaged in the 'win f'dow fra-me A as shownin'Figure 36, the can- " opy extensions 24 and 25 deflect the currents of air `upwardly from Without vthe enclosure Ato the interior thereof asindica'ted by the aiaowifn :said 'Figure 6 of the draw-ing.

'It will be apparent that the ventilator is uses as illustrated in Figures hese fabrics 19 fare fastened 'onftheir f each 'other as n capable of various adjust-mentsand position ings relative tothe Window traine, so that panel extending across the space between said plates, vertically and longitudinallyextending means secured to the plates foriix edly securing the. panel in position, said vertically extending means lconnecting :the
