May 6, 1952 s. o. RYGARD ARRANGEMENT FOR VENTILATING OF RAILWAY CARRIAGES BUSES AND SIMILAR VEHICLES 2 SHEETS-SHEET 1 Filed Oct. 25, 1947 JNVENTOR June 05.51am Rz gara BY MAM ATTORNEY y 5 I s o RYGARD 2,595,370

ARRANGEMENT F OR VENTILATING OF RAILWAY CARRIAGES, BUSES AND SIMILAR VEHICLES Filed 001. 25, 1947 2 SPEET$-SHEET 2 FIG. 4

INVENTOR Sune 055/011 Rygom (Mam M A TZOKNEY tion inlet for the used air or also from both of them in variable proportions.

The arrangement acts in the following manner. The air is sucked in through the opening between the cap I and the flange 2 and passes through the annular channel between the mantle l and the body I6 to the fan-wheel l9. From the latter the air will be conducted by way of a channel-system (not shown) into the vehicle to be ventilated. From the interior of the vehicle the air escapes through the openings 39 in the hubdisc of the fan-wheel l9- According to the position occupied by the body 16 agreater part or a smaller part of the used air and the entering fresh air will be mixed together and in this way the mixture will be tempered to the extent desired.

The invention is not limited to the illustrated embodiment. It may be varied in several ways Without departing from its principle.

The body l6 may for instance be made as a fixed one, the lower part of which is provided with adjustable openings, and the inlet and outlet channels may be changed, so that the inlet channel is placed in the centre and the outlet channel becomes the annular channel between the mantle and the body It.

The ventilating arrangement is preferably mounted in the ceiling of the vehicle in the manner indicated in Figures 1 and 2 and it may in usual manner be combined with a filter, heatbatteries and cold ones, humidifying devices etc. which may be required for an air-conditioning plant.

Having now described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:

1. In an apparatus for ventilating vehicles: a tubular passageway opening at one end to the atmosphere; a combined suction and exhaust fan at the other end of said passageway; means covering the atmospheric end of said passageway and providing separate lateral annular channels communicating therewith; and a tubular member mounted for axialniovement bridging the distance between said means and fan dividing said passageway into concentric intake and exhaust channels, the axial position of said member governing intercommunication of said intake and exhaust channels to control mixing of entering and exhaust air.

2. A ventilating device for railway carriages, buses and similar vehicles comprising: inner and outer conduits adapted to be mounted substantially perpendicularly to a wall of the vehicle and providing an inner centrally disposed channel and an outer coaxially situated channel, said channels each connecting with the inside and outside of the vehicle; fan means associated with said conduits to draw fresh air for the vehicle through One channelv and exhaust air from the vehicle through the other channel, means providing an opening for admission of exhaust air into the fresh air channel; and adjustable means to vary said opening whereby the proportion of exhaust air admixed with fresh air supplied to the vehicle is varied.

3. An apparatus as specified in claim 2 wherein said adjustable means comprises the inner conduit movably supported for axial bodily movement.

4. An apparatus as specified in claim 3 havin a cap surmounting said inner conduit on the extenor of the vehicle in spaced relation to said inner conduit, whereby axial movement of the inner conduit adjusts the space between the cap and inner conduit to vary the air flow through the inner conduit.

5. Apparatus as specified in claim 2, wherein said adjustable means comprises the inner conduitmovably supported for axial bodily movement, and a remote-control lever mechanism for moving said inner conduit.

6. Apparatus as specified in claim 2, wherein said adjustable means comprises the inner conduit movably supported for axial bodily movement, and wherein the conduits have cooperating guide means to prevent rotation of the inner conduit.

'7. A ventilating device for railway carriages, buses and similar vehicles comprising: inner and outer conduits adapted to be mounted in a wall of the vehicle and providing an outer channel for air surrounding an inner channel, said channels communicating between the inside and outside of the vehicle; a fan adjacent the inner ends of said conduits, said fan-having central blades for forcing air through the inner channel and peripheral blades for drawing air thropgh the outer channel and discharging the air tangentially; said inner conduit being located between the central and peripheral blades; and means supporting said inner conduit for axial movement to and from said fan to provide an adjustable space between the inner conduit and fan for proportioning admixture of exhaust air with fresh air supplied to the vehicle.

8. A ventilating apparatus as specified in claim 7 wherein the end of the inner conduit adjacent the fan is outwardly flared with its flared edge substantially in alignment with the edge of the .outer conduit whereby axial movement of the inner conduit simultaneously inversely varies the space between the fan and the inner conduit, and the space between the edge of the outer conduit and the flared edge to restrict flow of air through the outer channel.

9. An apparatus for ventilating vehicles comprising: an inner wall providing a central air channel; an outer wall surrounding the inner ,wall in spaced relation'to provide an outer end channel therebetween; fan means in at least one of said channels for driving air therethrough; means controlling communication between said channels adjacent said fan means; a cap surmounting said inner wall in spaced relation thereto; and means for varying the space between the cap and inner wall. v

10. An apparatus as specified in claim 9 having a lateral flange dividing the space between said cap and the edge of the second wall remote from the fan means, said cap and flange providing circumferential lateral passages connecting said respective channels and the surrounding atmosphere.

' 11. A ventilating apparatus as specified in claim 9 having a spindle secured to said cap and said latter means comprises said inner Wall slidably carried on said spindle.

12. An apparatus for ventilating vehicles comprising: a fan having a central set of blades disposed to direct air axially in one direction, and a set of peripheral blades to direct air tangentially; a sleeve mounted for axial movement toward and away from the fan between said sets of blades and providing a central air channel; a second sleeve surrounding the first sleeve in spaced relation to provide a second channel for air to the peripheral blades; a cap for the first sleeve carried in spaced relation thereto by the second sleeve; and a flange carried by the second sleeve between the cap and second sleeve to provide circumferential passages connecting said air channels to the atmosphere.

13. An apparatus for ventilating vehicles comprising an outer wall; a hood surmounting said wall in spaced relation to the edge thereof and having a downturned exterior flange and a central opening; a cap surmounting the opening of the first hood in spaced relation thereto and having an exterior downturned flange; a fan adjacent the opposite end of said wall; and a sleeve in spaced relation to said wall forming a central and a peripheral air passage and axially movable between the fan and the hood, said sleeve having its end flared adjacent the fan.

14. An apparatus for ventilating vehicles comprising: a fan having a central set of blades disposed to direct air axially in one direction, and a set of peripheral blades to direct air tangentially; a sleeve having a flared end adjacent the fan and mounted for axial movement between said sets of blades to provide a central air channel; a second sleeve surrounding the first sleeve in spaced relation to provide a second channel for air to the peripheral blades; and a cap for the first sleeve carried in spaced relation thereto by the second sleeve.
