VENTILATOR.

Application led December 19, 1927. Serial No. 240,959.

My invention relates to ventilators more especially intended for railway passenger cars and has for its object the provision of a construction which will automatically adjust itself to the direction of car travel so as to permit the vitiated air to be exhausted from the car interior.

The invention also contemplates means for closing the ventilator when necessary to exclude cold air and also to prevent ingress of snow or rain; while at the same time involving means for preventing ingress of cinders.

The objects and advantages of my invention will all be readily comprehended from the following detailed description of the drawings, wherein Figure 1 is a partial side elevation and partial sectional View of the ventilator.

Figure 2 is a partial end elevation and partial sectional view of my improved ventilator. l

Figure 3 is a partial plan and partial sectional plan view of my improved ventilator.

Figure 4 is a perspective view of one of the deilectors,

My improved ventilator, which is especially adapted for use on railway passenger cars, is intended to be placed on the roof of the car over a suitable opening therein. The ventilator, which has an open bottom, in the particular exemplication, consists of a rectangular frame or housing of larger dimensions at bottom than at top and provided with

end walls

10, 10 and a top 11; the ends and sides being shown sloping outwardly toward the bottom at 12 and terminating in the verticall disposed base portions 13 which are a apted to iit onto the roof of the car about a suitable opening therein.

The sides of the ventilator intermediate of the base portions 13 and the top 11, are cut away to provide large openings at 10a; and both sides are providedjwith a plurality-of transversely disposed partitions 14 arranged parallel with each other in spaced relation to provide the passageways 15 therebetween. These partitions may bein the nature of vertically disposed plates having laterally bent upper and bottom ends or flanges 16 to provide suitable means for securing the same in place.

The two sides of the ventilator are provided with cover members 17, with one longitudinal side of each cover or housing secured tothe ventilator top 11 as shown at The sides of the ventilator, within thev covers of housings 17, and adjacent to the partitions 14, are provided with a plurality of vertically arranged deflectors 20 and of the general construction more clearly shown in Figure 4; that is to say, the deilectors are arranged to swing on the vertically disposed pivot pins or trunnions 21. The upper end of each pivot pin or trunnion 21 is rotatably supported in place by a suitable bracket 22, while the lower end of each pivotpin is supported by an angle plate 23. The lower ends of all the pivot pins are held in position on the respective angle plates` 23 by means of an apertured guide plate 24 extending lengthwise of the. ventilator as shown in Figure 3. 1

The various deilectors 20 are preferably arranged equi-distances apart and, with the exception of the intermediate deflector 25, are each shown provided with an inwardly disposed portion or wing 2 6 of such width, relative to the distance between the pivot points of the deflectors and the partitions 14, that said wings will engage with either of the adjacent partitions 14 and thereby prevent a positioning of the defiectors parallel with the sides of the ventilator. Thatis to say, the deflectors 20are provided with the wings 26 so that the degree of swinging movement ot' the deflectors will be limited by thev wings 26 engaging with one of the adjacent partitions 14, as shown in Figure 3, where it is assumed that the direction of travel of the car on which the ventilator is placed would be toward the bottom of the sheet containing said figure so that the outer air will be rushing lengthwise through the housings 17 in the direction of the arrow.

As thev deflectors are all of substantially uniform width and spacing, the position of the intermediate delector 25, relative to the adjacent partitions 14, is such that proper movement of the intermediate deector 25 would. not be possible if it were provided with the wing 26 and for that reason I show said deflector provided at bottom with a depending strip or stop member 2Gu adapted to engage the bottom oi the side of the ventilator to prevent the too 'far inward swinging movement oi? the deflector. In other words, the

dei'lectors

20 and 25 are provided with the

stops

26 and 26, respectively,

l to prevent them from swinging into a laprection of travel.

Disposed lengthwise of the main housing of the ventilator at a point intermediate the top and bottom thereof, namely at the longitudinal laxis of the ventilator, I provide a brace strap or plate 27, see Figure 3; with ythe ends thereof shown bent downwardly and suitably secured to the end walls 10 et the ventilator. This brace member or strap 27 is shown provided with a longitudinal slot 28 which is adaptedto receive a bolt 29. The bolt 29 also passes through the apertured ends ofthe

links

30, 30 and the bolt is held in placein any suitable manner, as `for example by nut 31 which may ,be held against rotation by a pin32 passing through the kbolt after the nut has been properly screwed into place.` `The opposite ends of the links`30,`30 are each pivotally connected at 33 to a bracket member 34 secured on the inner side of a door 35,; there being a door j ventilator'.

tion `in Figure o 35 foreach side of the Iventilator and each door ybeing of width and length sufficient to close the large openings in the sides et the These doors are each pivotally connected at one side thereof, as shown at 36; the pivot pins heilig supported by suitable brackets as at 37.

The

doors

35, 35 are shown in open posin in full lines and may be swung to complete closing position by 1nov ing the bolt 29 toward the opposite end of the slot` 28 so as to bring the links 30 and their pivot points substantially on dead center as shown in dotted lines in Figure 3.

The sides of the ventilator adjacent to the openinfrs 10L therein are each provided with a Vsuitzi-ble frameor strip 38 arranged in slight spaced relation with the main side wall of the ventilator for the purpose of receiving a suitable screen 39 which is adapted to cover the entire opening in each side wall and prevent ingress of cinders and the like. The `screens are intended to be removably held in place in any suitable manner whic will permit them to be slid downwardly out of the frame by flexing the screen., so as to enable cleaning and renewal ot the screen wire when necessary.

lVitli my Ventilator it is apparent that the dellectors will automatically adjust themselves to the direction of car travel or outer air currents and that with the outer air rushing through the open ended

housings

17, 17, an eduction of air from the car interior is induced throughpassages or channels 15. On the otherhand, in the event oi' severe rains, or the ingress of too much cold air, the ventilator may beclosed from the car interior by simply moving the connected ends of

links

30, 30 from one end of slot 28 to the other end thereof as previously described.

The construction shown is believed to be the best embodiment of the invention, but structural modifications are possible without, however, departing from the spirit or my invention.
