To all whom 'it may concern:

Be it known that I, JOHN M. DALY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain -new and useful Improvements in Car-Ventilatore, of which the following is a full, clear, and exact specification.

My invention relates to that class of carventilators in which are employed one or more longitudinal passages extending throughout the length of the car and adapted to receive air at either end,"which escapes into the body of the car through cross-openings disposed at suitable intervals throughoutl the length of such passages, such passages beingv usually constituted by means of the false flooring, composed of transverse slats supported upon and secured to longitudinal beams resting on the bottom or flooring proper of the car. With this system of ventilation it is found that when the car is loaded with goods or freight in a compact mass the spaces between the slats are substantially covered over, so as to prevent the air from rising into the body of the car, and consequently instead of percolating through the freight, as intended, it passes on' through the air-passage under the false floor- Ing and-escapes at the opposite end of the car wlthout having performed its allotted function. f

The primary object of my present invention, therefore, is to compel the air entering the passage or passages under the false floor to pass through the freight as its only course of escape. In accomplishing this object I construct a ventilator in which there is a longitudinal air-passage or a number of such passages extending lengthwise of the car and having openings disposed at suitable intervals throughout its length for admitting air to the interior or body of the car, and under each of these openings is arranged an inclined deliector which traps the current of air passing through the said passage and `deilects it into the body of the car through said openings, and in order that the air after rising through such openings and coming in contact with the freight may not again pass downward into the passage under the false floor the deilector is of course suiiicient in dimensions to completely underlie the opening. In this way the air has no course of escape excepting through the freight; but in Order that this air may be distributed throughout the transverse. extent of the car an open-sided channel is extended from the said opening in bothl directions, if necessary, over and across the longitudinal passage er passages, whereby the freight resting upon the false iioor and extending across such channel will form one Figure l is a plan sectional view, partly broken away, of a car provided with my improvements. Fig. 2is a vertical longitudinal section of a part thereof on. an enlarged' scale. Fig. 3 is a transverse sectional view taken on the line 3 3, Fig. 2; and Fig. tuis an enlarged perspective view of one of the deflectors.

, 1 and 2 represent, respectively, the side and end walls of the car-body, and 3 indicates the downwardly-extending passages usually employed in ventilators of this kind for admitting the air to theaforesaid longitudinal passages extending under and constituted by the slattcd flooring.

Il represents the longitudinal beams or sills which extend throughout the length of the car and upon which the transverse slats 5,con-

stitutiug the false flooring, are supported and` secured. The sills or beams 4, any suitable number of which may beemployed in conjunction with the slats 5, constitute one or sages 3, according to the direction in which the .car may be moving, as shown by the arrows in Fig. 2. In order that this current of air passing IOO through the passages 6 may be deflected upwardly into the body of the 'carthrough thel f4 channels or openings constituted by the slats 5, I arrange under each of the slats 5 a deector 7, which is' double-ended, so as to catch the air no matter which way the car is moving. This deflector 7 is preferably secured by nails or othermeans to the under side of the vslat 5 at its intermediateportion and extends.

downwardly towardthe floor proper; 8, in an inclined direction, and inorder thatA these i'nclined portions may be supported and their distortion from rough usage prevented each is ralso ysecured to one of the adjacent slats 5.

This may be best accomplished by prpvidingI` ea'ch of the inclined portions with upwardlyextending side pieces), whose upper edges are each provided .with an ear 10, which underlies and is secured to one of the adjacent f slats 5, while the intermediate portion of the middle slat 5. deflector do not extend entirely to the floor 8, g

deflector is given a flat form 11, extending llaterally iin both directions and having perforations wherebyit may be nailed to the The inclined portions of the so that when the false .iloorings constituted by the slats 5 and lbeams 4 are 'taken out of the car and'stacked up as usual none of the weight will be sustained by the lower ends of the deilectors. The deflector, made as shown and described with reference toFig. 4, is employed whenjit is desirable to secure the deflector midway between the sills or beams 4;

but in instances Wherethe dei'lector' may be arranged against one of the .beams or sills 4 the upwardly-extending-portions 9 and ears 10 on one side will of course be unnecessary, and each of the inclined portions on that side may be provided with simply an upturned ear 12,

-' las shown in Fig. 3, whereby the inclined porflanges or side pieces 9, however, perform the tion may be nailed or otherwise secured to the contiguous beam 4. The u pwardly-extendimgI furtheruseful function of preventing the air from escaping laterally from theinclineddeflectors back into the passage 6, and in order that the air may not thus escape back into the passage 6 after it has risen above the 'edge or edges of the side portions 9 the space between the slats 5 is closed by a strip of sheet metal vss or other suitable material 13, extending under vand secured to the slats 5 and projecting from one or both' sides ofthe deflector 7, according to whether the delector is arranged immediately ycontiguous to one of the beams 4 or at apoint intermediate between such beams. Y As shown in Fig." 3,. the middle deflector is located at a point intermediate between the beams 4, and

' consequently one of the plates 13 extends from each side of the deflector to theadjacent beam -.4, over-which` it laps, and, if desired, it may be tacked or otherwise-secured thereto. Consequently the air striking the middle deflector is compelled to rise in to the cross-channel constituted byl the slats 5, and should the open upper side of this cross-channel be substantially closed by compact freight supported across it the air entering-through the openlin-g immediately above the detlector would be compelled to pass along between the slats throughout the entire transverse `extent of the car, and if it escapes at all from such cross- -channel it must escape .upwardly through`- the freight, because the opening betweenl the slats is closed by the plates 13 throughout the transverse extent of the car on cach side of the delector.

The dellectorsare 'preferabl y of lesswidth or transverse extent than the distance loe- 'tween the beams or sills 4, and they are so arranged that'the air escaping past-onein the passage 6 will strike the' next one at a point farther along the passage, and the current escaping past that lone will strike stilly another -one arranged out of line therewith and at a still farther point along the passage. In this way the first deflector, arranged at the farther right-hand corner in Fig. l, may be madeto drive the air from one-side` of the car to the other between the slats 5 and plates 13, as shown bythe arrows. The next deflector, which is arranged at an intermediate point between the two middle sills 4, is made to drivethe air in both directions across the car, the amount escaping downwardly on one side, where the rear end of the first dellector is arranged,being immaterial and only adding to the current, which will4 be caught by the deflector arranged at the point 14 and again driven upwardly into the'bodyof the car.

The next dellector, which is located between the near pair of beams 4, as seen in Fig. 1, also drives the air in both directions across the car, and that portion of the current which escapes downwardly through the opening over the rear side of the middledefiector just described will be trap ed by the deilector arranged at the point 1 and. again driven up- IOO wardly into the car, and soon throughout the I ther along the passage, said deflectors being of less width individually than said passage but the sum of their widths ,being substantially equal to the width of said passage, substantially as set forth. i

2. A car-ventilator having in combination a. false floor constituting an air-passage having openings leading upwardly into the body i of the .car and' deiiectors arranged 1n saidV IIO passage under saidv openings and being substantially equal tothe dimensions thereof so asy to completely underlie said openings, substantially 'as set forth.

3. A car-ventilator having in combination a longitudinal passage having end openings for the admission of air thereto and dischargeopenings disposed at intervals throughout its length and an open-sided channel extending horizontally from said discharge-opening and over and across said passage, and deiectors arranged under said discharge-openin gs, substantially as set forth.

' 4. A car-ventilator having in combinationl a false iioor provided with transverse slats arranged with spaces between them, a deflector secured to one of said slats and having its opposite ends inclined downwardly and oppositely and each secured to anY adjacent one of said slats, substantially as set forth.

5. A car-ventilator having in combination a false iloor provided with transverse lslats arranged with a space between them, deflectors extendingdownwardly from said slats and -having the side portions 9, and plates extending from said side portions and closing the under side of the space between said slats, substantially as set forth.

6. A car-ventilator having in combination a false iloor provided with slats arranged with a space between them, deflectors secured to one of said slats at its intermediate point and having its opposite ends inclined downwardly on each side of saidv slat and being provided with ears 10 each secured to the under side of one of the adjacent slats, substantially as set forth.

7. A car-ventilator having in combination a. longitudinal air-space provided with end openings for the admission of air thereto and stantially as set forth.
