To it my. concern: 7 Beit known that LvHosmnn W. LEEDS, a citizen ofthe United -,States, residing at-Seligma'n, in the county of. 'Yavapai and: State of Arizona, have invented certain new and useful Improvements in :Car Ventilators, of which the following is aspecification. 5

The, present invention'relates to that general type of ventilator covered by-my United States Letters Patent Nos. 948,144 and 1,211,602, and more especially to an improved ventilator adapted for use in passenger cars. V I The principal objects of the invention are to provide an eflicient ventilator which is compact in form; which is cleanly in 1ts operation; whichis adapted to be inserted readily in a car-windowor equivalent ventilatin opening without ;materially obstruct-v ing 51c vision, therefrom; and which may easily be removed and, if desired,-rev ersely inserted in a window-when the direction of movement of-the ear isjchanged; .-My im-- provedventilator isalso adapted for use in 2 the deck Windowsof railwa cars, andis so constructed. "and. arranged ft erem as to am tomatically and -thoroughl ventilate the car when moving in either lrectlon.

Further objects and advantages of the illvention will appearas the nature thereof is understood from the accompanying description and 'drawin whereina preferred embodiment is set orth for urposes of illustrating the principle of t e lnvention and not as unnecessarily limiting thescope of the appended claims.

In the drawing- Fig. lfis a top plan view of a railway car,

illustrating the Imanner in which the venti latorsmay be,adaptedlfor use in deck windows;

Fig; 3 is a horizontalj enlarged section.

through a ventilator mounted, in. a car window; and I Fig. 4 is a vertical section taken on the hne 4-4'of Fig. 3." 4

With reference to the drawmg, the numeral 11 designates the jamb of a window at the base of which is the sill 12. The sash 13 is partly raised and permits the ventilator to be inserted in the-aperture between the bottom of sash 13, the sill 12 and the vertical sash guides 14.

The ventilator comprises a hood l6 slidably mountedupon a screen frame-17. The forward end and that side of the hood- 16 which is mounted on frame'17; are open.

a The upper and lower surfaces 18 of the'hood converge ,gshghtly towards. their point of.

The rear closed junction with said frame. end 19- of the hoodmerges in a gradual curve into the outer side wall 20.

A longitudinal partition 21 is vertically disposed 1n the hood parallel to side wall 20 for a major portion of its length. vSaid partiti'on curves at its forward end toward and joins the inner side of hood 16, forming a funnel-like mouth as shown at 21 in Fig. 3.

The partition terminates at its. rearward end I at a point substantially opposite the begin- .ning of curvature of side jwall120 into'the rear"wall 19'," thus formingimhood 16 a tortuous," air-entraining duct" leading from the -funnel-like opening 21? at the forward end of the hood, to that side of said hood spanned by the screen mesh off-frame 17 An outstanding :flange 22- projeets vertically around the inner open ,sideof the hood,

and is preferably formed continuous and integral therewith.

A keeper strip 23 is positioned on frame 17 and extends along both of the'horizontal frame members and one of the vertical mem- I bers.

strips about three sides of frame 17 receives the previously mentioned flange of the hood,

The groove thus formed by the keeper slidably inserted at that end of the frame having no keeper; In this way the hood is mounted securely upon frame 17, and is pre-- vented from movement thereon by the window-and screen guides 14'when said frame 11s positioned in a window. Y

A plurahty of shutter leaves 24 arepivot ally mounted between the horizontal members-ofiframel'lat such spaced intervals as to close efiectively-"the screenedopening in said frame ,asmay be desired. Said shut- A verticalpartition 27 is positioned near I the inner side of the. hood, and extends for ward from the'rear wall 19 to a point substantiallyosite the rearward termination of 'partltlon 21. Partition 27 is disposed parallel to the inner side to'the hood,iand only spaced therefrom a-sufiicient distance to avoid interference with the operation of shutter leaves24r. The-purpose of said partition is to direct forwardly the current of air entering through'the hood, and to di fiuse the same equally over the area of the screened frame.

Inasmuch as this type of ventilator 'is designed to be reversed in a window when desired, that part of itwhich was the bottom naturallywould become the top. Therefore the top and bottom portions of thehood, ill-- cluding the construction therein, are duplicates of each other, and: the following description of the bottom will suflice for the top. As previously stated, the upper and. lower surfaces of the hood converge inwardly, thus causing any rain water, cinders, or the like entering the hood to gravir tate toward the outer, lower side thereof.

A plurality of small apertures '28 are spaced inthe bottom of the hood along said outer side and serve to discharge any foreign matter such as water, cinders, dust and the like carried by the air and entering the hood at its forward open end.. Another small aperture 29 may be positioned in the bottom of the hood between the partition 27 and the rear wall 19forthe purpose of dis-- charging therethrough any of the foreign matter which may have passed beyond apertures 28 and beyonda baffie plate 30 which extends across the bottom of the hood between the rearward termination of the partition 21 and the side wall 20, as shown. At this point, in the lower portion of said side wall, is provided a discharge opening 31. Said bafie'plate 30 functionsto obstruct and to deflect any foreign matteninto the openin 31.

hen the direction of motion of a car equipped with. this type of ventilator is to be changed, the ventilators may be reversed in one of two] ways. 'Inthe first, the screened frame to which the hood is attached I may be turned end for end, in the window; alternatively the hood may he slid horizontally from its engagement with the keepers on the frame,.reversed and again slid into the keeper ooves.

cleaning because the interior portion of the hood and inner side of the screened frame carrying the shutters are quickly exposed by simply sliding said hood from its retaining keepers in the frame.

til ators, as illustrated in Fig. .1 maybe inmanages ate a suction which draws the air therefrom.

Thus with such an arrangement of the ventilating means, the carfis most eiiicientlyventilated when traveling in either direction.

. ile the above detailed description is" basedupon an embodiment designed ticularly for use in passenger car win ows yet it will readily be-seen that such a ventilator may advantageously be our loyed in many other types of enclosed vehic es.
