My invention is adaptable to a refrigerator car having spaced apart walls 2, an insulated roof 3, an insulated floor 4, a foraminous floor or floor rack 5 above the insulated floor, and anairspace Bbetween said floors.

A` refrigerant container 8 is positioned sub- A hatch opening 9 is provided preferably in the roof of the car above the refrigerant container 8 for filling it with a refrigerant, removing the refrigerant or cleaning the container. The hatch opening 9 may be provided with the usual plug, lid, locking and supporting mechanisms. A drain having a closing valve may also be provided for the container.

Under certain conditions frost will on .the bottom I0 of container 8. To pre# vent melted frost from dripping onto the lading, an insulated partition II provided withl a form i drip pan I2 is positioned below and spaced from the container. The space I3 between the container bottom I8 and the partition II forms a flue so that air may circulate therethrough and be cooled by contact with the chilled container '5 bottom I0.

To support the container 8 above the partition Il metallic spools I4 and 34 are provided. These spools are arranged in spaced relationship to. each other and have their upper ends I5 secured to the 10 container bottom I0. In the drawings I have shown the spools I4 and 34 secured tothe container bottom by Welding but any other suitable means ma-y be used. The lower ends- I6 of the spools I4 and 34 are adapted to rest upon the 16 drippan I2 of partition II.

To support the partition I'I I provide carlines Il upon which'the partition rests. These carlines Il extend transversely of the car and have their ends I 8 secured to the car walls 2 2. the above described construction the entire Weight of the refrigerant container 8, the refrigerant within the container, and the partition II is carried by the carlines I'I.

In the preferred form .of my improvement the .25

members 2'I span the spaces 28 between the ends .40 vof adjacent containers 8 8 and support the' insulation thereabove.l At the eaves I provide the -sheet metal members 29 to support the roof insulation,

To prevent the refrigerant container 8` from :45

shifting due to service movements of the car a plurality of depending studs or dowel pins I9 pro- 'truding below the roof 3 are provided. The studs lI!! v vare rigidly secured to the roof structure preferably to a member such as a roof carline 28 by 50 welding or other suitable means. The sides 2l of the container 8 are provided with outwardly extending flanges 22 having holes of suitable size arranged and positioned so as to engage the studs I9 when the container 8 is in position.

With f2s This arrangement is shown in '30 The top 24 of container 8 will support that .them off an end of the carline.

Another means for preventing shifting of the refrigerant container is provided by securing an upwardly extending metallic member 3i) to the top of a carline Il; this ma-y be accomplished by any suitable means but I prefer to weld member 30 to carline Il'. Member 3G is positioned on the carline l1 so that when container 8 having a spool 34 is assembled in the car with partition Il and carline il the member 36 will extend through a hole 3i provided in partition Il and enter the hollow spool 34 engaging the inside of the wall 3.2 thereof.

I have also found it desirable to tie the container 3, the partition ll and the carline l together by some readily releasable means. For this purpose a depending bolt 33, having its upper end 35 anchored within a hollow spool 34 and its shank 35 extending through the member 3G so that its lower end Sl extends through a hole 38 in carline l1 and is adapted to receive a nut 39 or other suitable securing means, is provided.

In the conventional refrigerator car lused for transporting meats, a. meat rack positioned near the roof and extending over the lading space is generally provided. Such a rack generally consists of beams extending transversely of the car between the walls in combination with and supporting -rods or rails spaced on fixed centers and extending lengthwise of the car above the lading space.

With my improved construction a meat rack is not necessary as I propose to utilize the carlines il from which to hang a lading such as is generally suspended from a meat rack. In the preferred form of my improved refrigerator car construction the carlines Il are of an inverted U section having the depending sides 49 of the U terminating in outwardly and upwardly extending anges il of uniform width throughout the entire length of the carline. For attaching or suspending a lading I provide the members 152 having their central portions shaped to suitably engage with the conventional type of meat hook i3 and their ends 134 rebent so as to .engage the flanges il of carline i7 when the member 42 is in an operative position. A predetermined number of the members l2 may be placed on each carline by sliding them on before the carline is positioned in the car. After the carline Il is assembled together with theother elements of the car superstructure the members' l2 are theft proof as they can be disengaged only by sliding The slidable feature described above is an advantage over the fixed spacing of the longitudinally extending members of the conventional `meat rack as the attaching members d'2 automatically space themselves according to the size of the package suspended therefrom.

To simplify the installation of the carlines I'l I provide the longitudinally extending members 5I suitably spaced above and parallel to the car 'line Il' adjacent the end thereof. Inl the preferred Aconstruction a `member-'5l extending sub- .2,207,674 stantially the fulllength of the car is provided i for each of the opposite walls 2 2, each of said members having a. pluralityof spaced apart gapsk 55, said gaps being spaced to bring them underl the ends of the carlines i7 when assembled. Relatively short members 56 having their ends 5l' adapted to rest on the shelf 5d with, their central portions 58 spanning the gaps`55- are pro-y vided to support the ends of the carlines il. The' members 55 preferably are secured to both the longitudinally extending members 5l and the carlines l'l after assembly in the car; Carlines installed as described above are easily put in placeor removed without disturbing the car wall structure.

To provide a circulatory system wherebythe air cooled by the refrigerant may enter the lading spaceand the air warmed by the lading may enter the cooling chamber I provide in or near the walls 2 2 a vertical duct 43 extending from near theiloor 4 to near theroof 3, `saidduc't having its upper portion i4 communicating with the space I3 between container bottom ,lil and partition l! and having its lower portion communicating with the space f5 between the iioor The vertical duct L33 is sepa- Aof the car are spaced apart to provide lan air passageway l5 adjacent the longitudinal center of the car through which the warm air rises "and moves into the refrigerant chambers on: opposite sides of the car. The inclined partitions l l di- .rect the air warmed by vthe lading into and through the passageway Q5. f

The margins of the inclined partitions il adjacent the passageway d5 may lbe `pro-vided with insulated members iextending upwardly therefrom so as to further rraise the bottom of the air entrance ports into the refrigerant chamber above the lower portion of the inclined partition Il so as to cooperate with the inclined partition to direct the movement of circulation of air.

These members d@ are spaced away from the .refrigerant containers to provide fiuesY il therebetween.

The insulated partition! i vbelow the container 8 and the insulated partition 55 between the side n wall 2 and the lading space are associated to forma continuous uninterruptedfinsulation from the passageway l5 to the'foraminous oor 5. The space I3 below the refrigerant container 8 land the duct 43 between the insulated'pafrtition A5l] and the wall-2 are associated and arranged to provide a continuous uninterrupted air fluefor i circulating air from the passageway l5 to v'the lspace 6 below theforaminous floor 5 so that Iheat from the lading space cannot be absorbed by the cold air circulating until the air has reached the space below the fo-razninous floor. Therefore air warmed by the `lading will rise vupwardly andbe guidedty the inclined `partition. al into the passageway 45 and enter the refrigerating chamber A`where it will be cooled and 4densirled by therefrigerant in container and therefore will dej,-

scend through iiue il and move dcvflnwardly along the kinclined partition H until it .reaches the vertical `wall ductA 43 which :it ,descends` by .gravity `.into the space l5 below the :foraminous vfloor from whence it rises to replace the aforesaid warmed air.

'I'he accompanying drawings illustrate the preferred form of the invention, though it is tobe understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.
