CAR VENTILATOR Application led September 8, 1930. Serial'No. 480,565. 4

This invention-relates to ventilators and more particularly to a ventilator for use in connection with a railway car,'although it is to be `understood that it may be applied to any structure for which it may be found suitable. The present invention constitutes an improvement upon the construction shown in Patent,No.`1,746,009, obtained vby 4me and JosephI A. Bombard February 4, 1930.

Oneobject of the invention is to provide a car ventilator adapted to vbe applied to a window frame or other portion of a carin operative relation to an opening formed therein whereby fresh air may pass into the car and air within the car suckedl outwardly'when the car is in motion.

Another object of the invention is to provide an improved closure for aneck extending through an opening in the window frame 2o or car wall and so mount this closure that it may be easily moved to aclosed or to a partially or fully opened positionand thereby control passage of air into and out ofthe car.

Another object `of the invention is to so mount the closure that its movements through the neck maybe guided and the e X- tent of movement limited, thereby permitting the closure to be very easily moved toV a closed or an opened position and atv the same time prevent the closure from being drawn out of the neck too far when opened. Y l

Another object of the invention is to provide improved Vmeans for guiding passage of air through the ventilator when the closure isopen and very effectively prevent inwardly and outwardly moving air from interfering with each other and becoming intermingled.

Another object of the invention is to lprovide the closure with walls through which air may pass having screeningso applied thereto that there will be no danger of the screening catching against walls of the neck into which the closure fits and becoming detached or loosened when the closure is moved to adjusted positions.

Another object of the invention is to provide a device of this character which will be very neat in appearance and of such construction that it will operate properly with a car moving either forwardly or rearwardly.

panying drawings, wherein Figure l is a perspectivel view looking at the interior of a car having the improved ventilators applied to its window frames,`

Fig. 2 is a view in elevation looking at the ventilator from outside the car, portions of vthe ventilator beingl broken away,

Fig. 3 is a longitudinal sectional view takenv on the line 3-3 of Fig. 2,and i Fig. 4 is a transverse sectional viewV taken on the line 4*-4 of Fig. 3.

The ventilator is adapted for use in connection with a railway car,fsu`ch as shown in Fig-- ure l and indicated in general by the numeral l, and in this figure the ventilators 2 have The invention is illustrated inthe accom? 55 spaced relation to its ends and at it-s ends are disposed other screens 6 which together with the screensl 5 serve to prevent cinders fromV blowing into the open endof the body facing the direction in which the car is moving. It should be noted that the open ends of the body aredisposed in planes converging` downward-fv lys'o that rain can not easily drive into the vent'ilatorsand that since the bottom of thev r body slopes downwardly toward its open ends'any rain which may enter the` body will 7 of the body is formed intermediate its length with anopening and about, this o ning is disposed a neck 8 whichis engage through an 'opening 9 formed in thejwindow frame or wall' of the car. This'neckfits snugly in the opening and when screws` l() are passed through theJ ears 11 extendingfrorn the ends of the inner wall and engaged in the window frame the ventilatorwill be very securelyheld inv place. The collar-8 and the opening en- ,drain outof the same. The inner side wall i closed thereby are elongated longitudinally of the ventilator and the length is such that the collar may be divided into end sections of such dimensions that air can very easily pass through the neck into and out of the car.

In order to close the open end of the neck and control passage of air through this neck, there hasbeensprovided a closure l2. This closurelhas a head lfformed of sheetzm-etal and walls 14. The head is of greater dimensions t-han the neck and of the sameoutline and Ythe -wallsarevcf the same outline asv the neck and of such dimensions that the closure has snug telescoping fit within the neck, as clearly shown in Figures 3 and Il. Therefore,

the closure may be slidl through the neckinto.

and out of a. closed position and when closed marginal portions of the head will bear against a facing band 151secured against :the inner tace offtliewindow frame inl-overlappingxrelat-iontotheopeni-ng 9V and walls of the neck. Theclosure-wall is of an open constructionl-in .'orderzto permit `free passage of air-.whemthe closure is open and 'has circumferentially extendingfstrips or bands lr6 connected by `spaced bars or vstrips '17. 'Screening 18 is secured against thein-ner surfaces of the Walls and servesrvery effectively to screen air passing through the closure as well as constitutinga. reinforcement for the walls. Therefore,.t heclosure may be :grasped by its handle .19fandthrustintothe neck or drawn outwardly l.therefrom without danger of bendingftl-ie strips la. A partitionor plate 20 is secured in the closure intermediate its length, and from an inspection of Figures 3 and #Lit will be seen that this plate ext/ends transversely inthe-closure .with one endifixed to the head 13 and its side edges secured to the'walls of the closure. A companion partition 2l is mounted in the body andthis partition consists of plates or sheets 22 Ywhich are securedfvto'the outer side wall of the body andare curved, as shown infFigure 3, so that theylextendfro-m.the outer side wall in converging relationto each other. Reducedportions 23 ofthe partition plates :22,eXtend-in-to the neck iin Vparallel relation to each other andthesereduced endportions which are of less-length then the `Vdepth `of the neck have theirlfreeends bent t0 form lips '24 extending ing diverging relationto each other. .By this arrangementtheflips will serve to guide the partition-plate ,2 0y between the .reduced'ex tensions 2370i' the partition plates 22 when the closure isfittedinto the neck and since the plates from which the partition 2l is formed are resilient theywill have close contactingengagement with` opposite side faces of therpartiti'on plate'20 and therebyicause the .tubular bodypvof 'the ventilator and its neck tofbe divi'dedinto air passages leading from. oppositev ends ofthe body .and at Vtheir inner ends extendingithrough the neck. e Since thevbody portion vandgneck ofthe ventilator havefbeendivirded intoseparate air passages, air imay-pass-inwardly through-one air pasguide and limit movement of the closure and in order to do vso there has beenyprovided posts 25 carried f -by the lventilator -body 'and projecting into the neck near opposite ends lthereof and stems 26 secured aga-inst the inner face of the closure head near opposite ends thereof. Tlieposts are hollow and slidably receive the stems and each stem carries alpin 27 'which projects tra-nsversel'ywtherefromandisengagedthrough aslot 28fformed longitudinally in its cooperatingpost'. yTherefore-sliding movement ofj the closurelwill be gnidedby-the stems .which areslidably yrev ceivedlintheihollow-posts and-thelfact that the stems' carry pins engaged through slots in the posts will ylimit l sliding movement fof the stems and Athereby prevent the closure from being draw-n outward'lyfbeyond yalposition in `whiehit-is engaged in thevneck. .It Will thusbeseen .that there will be no danger ofthe: closurelbeing drawn outvtoo far byan inexperienced:- person opening the ventilator.
