VENTILA'IING DEVICE.
' Application filed February as, 1912. ,Serial No. 680,016. a, I
Specification of {Letters .Iratent; Patented Dec, 24,1912.
stantly to drain the foul air from the coin-; partment of the car without creating a draft;
or permit-ting the air from outside to blow-;
in and, consequently, ,without admitting? dust or smoke from outside. In accomplish: 1
ing these objects I employ primarily a draft? casing placed adjacent a wall of the car, said casing being extended longitudinally alongside said wall and having an expanded} (or funnel shaped end turned in the direction I of movement of the car, which end will thus be positioned to be forced against the at'mos-g phere as the car moves along and will collect and compress acurrent of air which will travel through the casing or passage at a high speed. Within this outside casing I:
place a series of tubular members having} one end penetrating the wall of the car so as to open-inside thereof. These members are:
curved at right angles parallel to the direction of the'car wall and extend longitudi-I nally through the casing. They are pro- ,vided with means opening the same into the:
chamber of said casing for collecting and compressing a part ofthat current in the tubes themselves, which compressed inner;
currents will act to draw air from the can and deliver the same from the end oft-he tubes into and out of the end of the casing,
The full objects and advantages: of m invention will appear in connection with the detailed descriptionthereof and are pa'rticularly pointed out'in the claims.
In the drawings illustratingthe applica-: tion of my invention in one form,'Figure 1 1 is a front elevation of a portion of the car having'my invention appliedthereto, viewed i the casing 12.
1 from the front or away from the direction of movement of the car. Fig. 2 is afragmentary vplanof a portion of-a car having my invention applied thereto with the casing shown in section. y a I Uponthe roof of a car 10 provided with the usual cupola or longitudinally raised 1 central portion 11 is secured a trough 12.
which may be rectangular orsquare in cross section and includes 'a passage way 13.
l Preferably the trough 12 will be applied to both sides of the cupola 11. At the front of the trough is a funnel like expanded portion 14 adapted to present a .considerable area to" the atmosphere as the car moves through it and thereby to gather together and compress a strong current of air. in the passage 13, as indicated by} arrows in Fig. 2. The funnel portion 14: may,if desired, be made removable so that when. the car is turned around the funnels canbe taken from one end of the casings 12 and placed on the other end of said casings.
Positioned within the casing 12 is a series a of pipes 15 each being turned at right angles as indicated at 16 in Fig. 2 and opening through apertures17 in the wall of the car into the inside of the cupola 11. The pipes 15 after the aforesaid'right angle'bend extend longitudinally in the casing 12 preferably as close to the inside wall of the casing as is possible while at the same time making a smooth curved bend at the point 16. On the side of these pipes ata point somewhat removed from the bend 16 and aperture 17 are formed openings 18. To the edge of'these openings away from the said bend 16 and aperture 17 that is, away from.
the direction of travel of the car and the casing, raisedofiange-likehoods 19-are secured, which hoods, as clearly shownvin Fig. 2, extend into the passage 13some little distance beyond thewalls of the pipes 15, thuspresenting a funnel-like mouth directed toward the funnel or advancing end of The method of operation of myventilating device will be clear from an inspection of Fig. 2. As the car moves through the air a considerable amount'of air is gathered together in the funnel 14: and compressed and travels through the passage 13 at a speed which approximates that at which the car is moving. As this body of air moves through the passage 13 it reaches the pipes 15 where the area of the passage is diminished to the extent of the combined crosssectional area of the entire series of pipes used. This further compresses the current of air and when it reaches the openings 20 beneath the hoods 19 it expands into these openings, passes through the opening 18 and on through the continuation of pipes 15. The effect of the stream of air moving through opening 18 is to take frictional hold of the air in pipes 13 ahead of the opening 18 and draw a portion of this air along with it. Air from the car passes in to take the place of that carried along and powerful suction currents are set up which draw air from the car through the openings 17. There is thus a constant current of air in one direction drawn from the inside of the cupola of the car without possibility of any of the outside air with its accumulations of dust and dirt passing back into the car. Air will enter the car to take the place of that leaving it through minute apertures in the walls and around the car windows, or if desired special apertures provided with air strainers may be employed for this purpose.
While I have shown this ventilator as applied to the side of the car cupola, since this is a convenient and satisfactory place, I do not wish to be limited to such an application, as the principles of the invention make it possible to apply the device to any other portion of the car, as, for example, just below the floor if this were found desirable. It will readily be seen that my ventilator is simple in construction and can readily be applied to cars as now built without extensive remodeling. It requires no power to operate the same, the actuating force being the ordinary movement of the car through the atmosphere. Instead of employing ventilators at both sides of the car it is practicable and is contemplated by me to use but a single ventilator at one side of the car, in which case the ventilator at the other side of the car may be turned the other way and the ventilator turned away from the direction of movement of the car can be closed so that the ventilating system can be used whichever direction the car may go without turning the car around.
I claim:
1. A car ventilator comprising a casing open at both ends and extending in the direction of travel of the car, tubular members extending longitudinally within the casing and through the wall of the car to the interior thereof, and means for collecting a portion of the air currents passing through the passage within the casing and causing them to enter the tubular members at a point at the rear of the point of entrance thereof into the car.
