VENTILATING AIND nnrtncrrnsor n13 THROUGH BAILWAYCARS.

Application filed June 14, 1926, Serial No. 115,843, and in CanadaMay 28, 1926. I

Hereto fore it has not been possible to obtain proper ventilation in railway cars and particularly in so called reirigerator express cars for carrying perishables because the air fectively difiused throughout the car. The

' object of myinvention is to diffuse tresh'air' upwardly throughout the interior of the car from the floor.

To. this end my invention consists in pro-' viding railway cars and more particularly cars for carrying perishableswith a ventilator whereby air is induced into the top of the car bythe forward movement thereof and practically theentire body of air taken in is precipitated downwardly near the forward end of the car and deflected into a flat air distributing member extending substantially parallel and comparatively. close to the floor communicatesapair. of intercommunicating oppositely curved deflectors, inside the car communicating wlth oneof the air intakes and disposed one below the other close to a side of the car. The top of the upper deflector projects within the ventilator and has its concave side towards that end-of thecar; and the lower deflector. rests in the corner of the car beneath the ventilator with its con cave side towards the body of the car and the upper and lower deflectors being arranged, as shown in Figure 2 with the upper in position todirect the downwardly-deflected air into the curve of the lower deflector. The lower deflector projects the air into an air distributor in the form of a floor rack which extends from'sideto side of the car and, the

air being thus deflected from the bottom ends of the lower deflectors, at that end of the car, to the bottom. ends, of the deflectors at the opposite end of the car. IInforder to control the volume of air admitted the upper deflectors are preferably carried by sliding plates serving as valves controlling the air intakes. Thesevalvular plates may be adjusted to vary .the intake opening or cut it off entirely. Each end of the car has a screened theupper portion of opening preferably located inthe lower portion of each of the doors otthe car and each is furnished with means for adjusting, or ii desired completely closing these screened openings. The mouths of the air intakes are adapted to exclude dust from the airadmitted by'vertically disposed fine screens; extending completely across the same.

-An equipment in accordance with the foregoing causes pure air topermeate the entire interior of a car and while it rises through the body of the car near the front endwhere it is admitted nevertheless it will be drawn down again as it nears the outlets in therear end of the car by the position of the outlets near the floor.

For full comprehension, however, of my invention reference must be had to the accompanying drawings in which similar reference characters indicate the same parts and wherein; v 7 A v Figure l-is an end View of a railway car constructedwith my means for ventilating and deflecting themair admitted thereto, through the bodyof the car, this view indieating one halt ofthe near end of the car in elevation and the other half of the opposite end of the car in elevation, the body oi the carwithin the last mentioned half as illustrated, being in transverse sectional View;

Openings 4 are cut throughthe main deck 2and extend in width from. upper .deck 3 to a point-pin line with the upper end of the side. wall of the car as shown in vliigure .1. Eachlof "these openings has a ventilatort A fitted therein and consistingtof a hood pre. senting a fiat top 5 with inwardly inclined back 6, Figure 2; the mouth of the ventilator having a screen 7 extending across it. The

screened mouth of the ventilator is located at one end of the openin 4. A pair of oppositely curved deflectors and C are arranged one above the other, the upper end of the top deflector projecting within the ventilator, and

is arranged with its concave side towards the end of the car while the lower deflector C rests in the corner of the car beneath the ventilator with its concave side towards the body of the car and in communication with the concave side upper deflector. Both deflectors are preferably arranged in close proximity to a side of the car and the lower deflector is preferably of slightly greater width than the upper deflector to facilitate the distribution of the air deflected thereto by the upper deflector. The openings 4 are closed by sliding valvular plates G upon one end of each of which is rigidly carried one of the upper deflectors B so that by moving the sliding plates the ventilators may be partially or fully closed or opened. When the ventilator is closed in this manner the upper deflectors being carried by the plates will be placed in contact with the end of the car and out of the way.

The air entering through the ventilators at the forward end of a moving car is deflected by the deflectors B and C and projected into a flat air distributing member consisting of a floor rack D. This rack consists of a false flooring composed of narrow spaced boards 8 supported at their opposite ends on cross pieces 9 resting on posts 10. The spaces between these boards serve as slits through which air may pass This form of floor rack admits the air projected along the floor by the lower'deflectors and the air thus admitted is distributed throughout the car through the slits. In each end of the car the usual door 12 has its lower panel removed and the opening thus formed is covered by wire cloth E. This screened opening is controlled by a valvular panel 14 slidable vertically in guides 15. \Vhen the car is put in motion the opening in the door at theforward end of the car is preferably closed and the opening in the rear door is regulated by its valvular panel in relation to the adjustment of the valvular plate G controlling the air intake at the forward end of the car. i

The device functions in either'direction as follows:

The speed of the car forces a current of air through the forward ventilators A in the roof and into the car where it is diverted by the deflectors B towards the forward end of the car and onto deflector C. Deflectors C, because of their greater width, spread out the air body and direct it into the space under the floor rack by which it is distributed throughout the car from which it is exhausted through the rear ventilators A and end opening E.

It is claimed that this system of air intake and the arrangement of deflectors, coacting with the exhaust ventilators and end exhaust ings are closed.

V11 at I do claim as my invention and which I regard as new and in which I claim an exclusive property and privilege and which I desire to secure by Letters Patent are 1. In a railway car of the type described the combination with an intake ventilator; of a pair of deflectors of curved form and located one above the other, the upper deflector being disposed with its concave side communicatin with the air intake, and the lower deflector being disposed with its concave side in communication with the upper deflector; a floor rack having the lower deflector communicating therewith, and an air outlet in the opposite end of the car.

2. In a railway car such as claimed in claim 1 wherein the intake ventilator communicates with anop'eningin the roof of the car; a slidefor controlling the roof opening and having the upper deflector carried thereby.

3. In a railway car the combination with a roof ventilator and a valvular plate for controlling the communication between the roof ventilator and the car; of means for directing the air from the ventilator towards the floor at the intake end of the car consisting of a pair of substantially vertically aligned curved deflectors, one being in communication with the roof ventilator with its concave side facing the end of the car, and the other deflector resting in the corner of the car beneath the roof ventilator with its concave side towards the body of the car, and in communication with the concave side of the upper deflector, and means extending parallel to the floor of the car for distributing the air throughout the car, and a screened opening with means for controlling the same in the rear end of the car.-

4. A railway car such as claimed in claim 3 and having the upper deflector carried by the valvular plate controlling the passage through the roof ventilator.

In testimony whereof I have signed my name to this specification.
