(01. 98-5) are made up and the car interior presents sub stantially a single free area. This invention relates to air conditioning sys tems for railway cars and more particularly to object of the invention is to provide methods‘ of and apparatus for distributing air ' forAnother distributing conditioned air within a sleep in sleeping cars, or cars where a plurality of 5- con?ned areas are provided for the use of passengers.

This is true or ?oor level and along the sides of the car, in com- 15 bination with an enclosing duct and branch Sup -coaches and, except for compartments, also 6? Pullman ‘type cars. The air may be introduced without regard to partitions or impediments tov 20 free circulation, because no such impediments exist. Thus, the air may be introduced in the upper part of the car, above the zone of occupancy, and will then ?lter‘ down into the passenger occupancy area. Normally, especially 25 under summer operating conditions when it is desirable to introduce air at a temperature below that of the atmosphere in the car, the air will be discharged from a central source of supply - through outlets located adjacent the ceiling area. 30 The distribution is such that the relatively cold ' Ply Conduits, whereby the 00115 may hellsed under winter operating conditions to heat air circulat ins within the" duct, and the duct utilized throughout the year for distributing conditioned 20 air to the car. The duct may be arranged with suitable ports to enable heating of thecar to be carried on in winter by natural air circula tion due to convection, the steam coils alone be-. ins used if desired; whereas in the summer time as the duct would be supplied with all‘ from any suitable conditioning and air handling apparatus.

The outlets, therefore, serve a double purpose and, additionally, provide for directing and throttling air quantities discharged therethrough. ' Another feature of the invention resides in the provision of a duct serving as ‘an enclosure for steam coils running along the side of the car at the ?oor level, and means including slides or the 10 like for enabling air from the car to circulate by convection in contact with the coils and then out into the car again. Another feature resides in the provision of a supply duct serving as an enclosure for steam 15 coils, in combination with a plurality of branch distributing ducts connecting to the supply ducts, the distributing ducts being positioned upon or constituting passages constructed integrally with permanent partitions or structural members of 20 the car. Another feature resides in the preservation of 8 supplies conditioned air from any desired source, such as a cooling unit or air washer. The duct runs longitudinally of the car on the out side thereof and therefore does not mar the in terior appearance thereof. However, the posi tition of duct 8 forms no part of the invention, and if desired, a source of supply from a condi tioning means may be otherwise suitably posi tioned as in the monitor area 9. An upper berth l0 and lower berth I l are divided by the usual 10 partition l2 which provides a bed support for mattress and bedding l3, when the car is made up for sleeping purposes. In non-sleeping pe riods, partition [2 is thrown upwardly against the side of the car, in the usual manner. Seat 15 l4, during sleeping periods, also serves as the usual bed support, when made up as a berth. Railing l5 serves as a support for curtains l6 which may be suitably designed to give individual con?nement and privacy both to upper and lower 20 berths. ’ the conventional appearance'of the car interior, Between rail l5 and the side of monitor 9, is and the avoidance of unsightly structure tending , the usual opening which communicates with the to mar the interior decorative e?’ect, either dur aisle area.

The various branch supply 40 tween sections of the car, to afford greater privacy to the occupants of each section during the day, ducts may terminate at different levels, and be their function during sleeping’ periods‘ being identical with that of the customary removable partitions. While desirable for such purposes, 45 these permanent partitions impede the free cir culation of air throughout the car, and give rise to problems of air distribution within said areas and between said areas and the rest of the car. Also, while in the conventional open type car, the prob 50 lem of air distribution within restricted areas arises during periods when the berths are made up, in cars of the partitioned or sectionalized type, the problem of distribution arises during non sleeping' periods, too. 55 , _ Figs. 6, 7 and 8 illustrate methods of air dis tribution within a railroad car particularly ap plicable but not limited to sectional type sleeping cars.

Or, if slide 54 is opened in addition to slide 53, a natural circulation in contact with the coils will be carried on through the two openings in the same way as heating now'takes place with 55 the coils exposed or surrounded by a grill.
