T0 allwhom it may concern:

'Be'it known that I, GARTH Gnirrirnz GIL- rIN,a citizen of the United States, residing at Riverside, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Ventilators, of which the following isajdescription, referencebeing had to the accompanying draw.- ing, which forms a part of my specification. My invention relates to ventilatorsmore especiallyadapted for railwayears and the like; and has; for its object the provision of a construction wherein the drafts or f outer currentsoi air are utilized to induce a suetion in the outletor discharging passage of the ventilatorwhich causes the vitiated air to be-withdrawn fromv the car-interior;

A further object of the invention is to provide a construction whereby the air-currents, regardless of their norinal direction, will be caused to flow in such manner as to provide anjefl ective degreeof "suction; and

whereby rain, cinders, and other foreign matter, will be prevented from entering the car-interior through the ventilator.

The objects of iny invention," aswell asthe advantages inherent in the construction, will be more fully understood'troin the following detailed description of the accompanying drawing, wherein:,' j Figure lis a perspective view of a 'por tion of a car-roof, showing: the application of niy ilnprovediventilator which is shown in vertical section] v Fig. 2 is a topplan and sectional View of my. improved ventilator.

Fig. 3 is a vertical sectional view of a modified form. Fig. 4 illustrates another modified form in elevation. V

In the particular exemplification of my invention, the ventilatoris shown applied to theusual ventilator window or opening of the clearstory of a inonitortype of carroof so "as to provide considerable clearance between the bottom of the ventilator and the lower deck of the roof the usual windowopeningbeing'shown at5 in Fig. 1 arranged in the sides of the clearstory; the ventilator being either secured in the opening or ad jacent theretoasshown,

VENTILATOR.

Speeifibationof Letters Patent. Patiq5ntgd Apr; gt'higllfi, Application filed February 7, 1916. S eria1No.7S,S4 5.

The'ventilator inxits preferred form coniprisesj a 'metallic housing having one side wall 6 and two end walls 7 ,7 "Theho'using is provided with'the attachingfiange-portiOnsSQpreferably made integral with the two end walls7,7 and alsomade continuous 'soasto extendfroni endwall-toendwall along the top and bottom of the construction. The sideadapted to be secured against haust openings'for the passage ofthe v'itiated air withdrawn from the car-interior through the action of the air-currents passing across theupper and lower edges of the windward or air-impinging wall or side of the housing. y

In order to prevent rain, snow, cinders and other foreign matter entering thecar-inte rior through the top or bottom of the ventilator,I provide the deflecting nieinbers 9 and 10 at the top and bottom, respectively. The deflector 9 at the top is shown integral with, or otherwise secured to the longitudinally disposed attaching flange 8 -i1nniediately above the car-communicatingopening, and is arranged to extend downwardly intermediate oftheend walls, the deflector being preferably materially larger or of greater width thanlower deflectorlOp Deflector 10 is formed integral with, 0 otherwise secured to, the lower longitudinallydisposed attaching'flange 8, see Fig. 1. The lower deflector 1O curves slightly up wardly toward its outer' edge, as shown in Fig. 1, so that anycross-currents'of air, as well as snow, rain, and other foreign substance, which are forced against thelower deck or adjacent the clearstorybeneath the ventilator will be deflected downwardly and faces.

the ear-interior and therefore prevented from entering through the window-opening in the car-roof. The deflectors 9 and 10 are both so formed to extend intermediate of the horizontal planes occupied by the upper and lower edges of the side and end walls; in other words the deflectors do not project beyond the outer walls or air-impinging sur- The deflectors 9 and 10 are so disposed that a considerable space or opening will be left intermediate of the unattached edges thereof, so as to provide a comparatively large space for the free egress of the ,vitiated air from the car-interior through the eduction or exhausting action caused by the outer air-currents.

With the ventilator secured adjacent the opening in the clearstory of the roof so as to provide the clearance between the ventilator and the lower deck of the roof of the car, it is apparentthat the ventilator will permit the foul air of the car to be with drawn either through the bottom of the ventilator or through the top thereof, which, in the preferred construction, are left practically entirely open, except in so far as the deflectors 9 and 10 areconcerned.

The two end walls 7., 7 and the side wall 6 are preferably made flat and provided with the horizontally disposed upper and lower edges which will induce the air-currents impinging against said walls to pass about said edges and across the openings in the top and bottom of the ventilator and thereby createan eduction action or suction in the ventilator which will cause air to be withdrawn from the interior of the car through the open side and between the widely. sepa ratedideflectors 9 and 10. a

As illustrated in the drawing, the walls 7 7, which I have termed the end walls, are disposed substantially at right angles to the longitudinal axis of the car, so that movement of the car, in either direction, will cause the air to impinge against the forwardly presented end wall and be directed across the open top and bottom and thereby cause a suction or eduction action in the ventilator as described.

In the event that the outer air-currents should be cross-wise or in a direction transversely to the car, the air will impinge against the side wall 6, and its passage over the edges of the side wall will likewise cause the vitiated air of the car to be withdrawn therefrom and forced to flow through the discharge openings of the ventilator.

Where the air-currents are in a downward direction, they will impinge against the downwardly sloping surface of deflector 9 and be caused to flow through the ventilator and ,be'discharged at the bottom; and in view of the fact that deflector 10 is made shorter than deflector 9, the air-currents.

through the ventilator as just described, will not be interrupted or in any way interfered with.

Any downward air-currents that may impinge against the wall or side 6 and pass over the lower edge thereof will assist the action of those passing downwardly through the ventilator, and by reason of the curvature of deflector 10 will be caused to flow about the end walls of the structure and also toward the lower deck of the roof, and therefore prevented from passing upward through the eduction or communicatingopening in the side of the ventilator and into the car.

In Fig. 3, I show a modified form of the ventilator, which, in general construction, is identical with the construction shown in Figs. 1 and 2, the modification comprising a number of louvers or baflle members 11 arranged intermediate of the deflectors 9 and 10 and extending from end wall to end wall the louvers being preferably arranged in staggered relation to each other as disclosed in Fig. 3, so as to provide sufiicient openings intermediate of the longitudinal edges of the louvers 01' battle members and the deflectors 9 and 10. I have shown the construction disclosed in Fig. 3 provided with the three baffles or louvers, but it is apparent that any suitable number may be employed which will prevent foreign substance being forced through the open side or CiIl'-C0ll1- municating opening of the ventilator through the action of any cross currents that may impinge against the ear-roof beneath the ventilator, especially when the car is not in rapid motion.

In Fig. 4, I show another form of my improved ventilator, (that shown in the preceding figures being, however, the preferred form) wherein the walls 7, which I have termed end walls, are swelled outwardly, somewhat in the nature of a horizontally disposed V, in cross-section; the general construction of the ventilator, however, being identical with the construction previously described and shown in Figs. 1 and 2.

I have shown and described these embodiments of my invention, but modifications in certain respects may be made without, however, departing from the spirit of my invention, and I do not wish to be understood therefor as limiting myself to the exact construction shown and described.
