WlNDOW-VENTILATOR.

ence being had therein tot e accompanying drawings. 1

This invention relates to a window-ventilator, and particularly to a casing adapted to be interposed between the rail of the sash and the top or bottom of the windowframe. The invention has for an obgect to rovide a telescoping casing'adapted terior partition curved for a ortion of its length concentric with the wal of the casing and its upper end diverging from said wall, so .as to provide an enlarged discharge-opening and prevent a direct upward flow of the draft,- which would .disturb a shade or ourtain, and to diffuse the air entering therethrough.

A further object ofthe invention is to provide means for supporting the ventilator-casing in position either upon the windowframe or upon the sash therein.

Other and further objects and advantages 'of the invention will be hereinafter set forth and the novel features thereof defined by the ap ended claims. Y

n the drawings, Figure 1 is an elevation of a window with the ventilator applied at the top and bottom thereof. Fig. 2 1s a vertical.

The numeral 1 designates a window-frame,

which may be provided with a lower sash 2 and an upper sash 3, the same being of any desired construction or configuration. The

ventilator 4 is formed in two sections-tele scoping and slidingly mounted upon each other, so as to be ad ustable for windows of difierent widths, and each of the se, sections is rovided with an end wall 5, while the inner face of the ventilator is curved, as shown'at'" 6, and provided with a flat seat'7 at its base. Within the'casing a puma 'partition8 is se-. cured and for a portion of its length extends.

concentric with the outer wall 6, thus forming a curved passage 9, through which the air passes in entering the room and which prevents any direct inward or u ward draft.

The upper portion of this partition is deflected from the wall 6, as shownat 10, thus providing an enlarged discharge portion to permit the diffusion of the air and its delivery into the room at a point removed from the sash, so that the curtain or shade will not be disturbed by the entering air. The casing is open at its outer face and is rovided with t e de ending lug 11, adapte to seat either upon the outerface of the sill 12 atf the lower portion of the sash or the outer face of the to rail 13 of the upper sash.

in its main features the construction of the ventilator used for the top and bottom of the window are similarexcepting so far as the means for supporting them in position, and for this purpose the lower ventilator is provided with a slot 14 in each of its'end walls, terminating in an enlarged opening 15,

through which the head of the screw 16 may be passed'and the ventilator slid downward until the shank of the screw enters the slot 14. This method of attachment retains the sections of the telescoping casing against movement upon each other and also against movement laterally on the sash, while the lower portion of the casing is held by the, lug The opening through which the air may enter the casing 11 against such movement.

is adapted to be varied by an adjustment of the elevation of the lower rail 17 of the lower sash, as will be seen in Fig.1. b

he upper ventilator is adapted to mounted upon the rail 13 of theupper sash by means of the plate 18, which, in connection with the lug 11, embraces this rail. It

will be obvious that this plate can be omitted and the casing retained by the lug 11 and the contact of the top of the casing with the surfaceof the window-frame.

. i The 0 eration of the invention will be unthecurved' partition to direct the entering current of air is ada ted to secure the most efiicient re sults,.whi e avoiding drafts in the room adjacent to 'the'window, and embodies the same-1n a simple and economical construction. The means for attaching the casing is adapted to hold the same against any movement relative to the sash oraecidental displacement when in use, while either ol the ventilators can he quickly and conveniently removed when found desirable.

I'Iaving now described my invention and set forth its merits, whatl claim, and desire to secure by Letters Patent, is

1. A window-ventilator coin )rising a oasin provided with end walls and curved lace,

and a partition extending for a portion of its length. concentric with said hire and diverging therefrom at its upper portion to provide an enlarged discharge-opening.

2. A window-ventilator comprising a easing provided with end walls and curved face, a partition extending for a portion of its length concentric with said lace and diverging therefrom at its upper portion. to provide an enlarged discharge-opeeing, a supportingbase for said casing, and a depending lug at one side of said base.

3. A window-ventilator comprising 2, casing provided with end walls and curved face, a partition extending for a portion of its length concentriowith said face and diverging therefrom at its upper portion to provide an enlarged discharge-opening, and ieaded securing devices carried by the frame of the window at each end of said casing and adapted to enter a slot therein.

4. A Window-ventilator comprising a casing formed of telescoping sections each provided with one end wall and with a curved inner face extending downward to the supporting-base, and a telescoping partition secured to the endwall of each section and ex,

tending at its lower portion concentric with the curved wall of the casing and diverging therefrom at its u per portion.

In testimony whereof I affix my signature in presence of two witnesses.
