Patented Feb. 6, 1951 UNITED STATES PATENT OFFICE CONTAINER HAVING REFRIGERATED PARTITION 10 Claims.

This invention relates to an improved refrigeration container assembly for storing and shipping purposes.

One purpose of the invention is to provide an improved means for shipping pro-cooled materials which are initially reduced to a very low temperature.

Another purpose is to employ refrigeration members that will act as heat diffusers.

Another purpose is to employ a hinged door or partition carrying refrigerant.

Another purpose is to employ a hinge sealing means which disconnects the refrigerant when the partition is open.

Another purpose is to employ a common manifold for feeding refrigerant to a plurality of partitions and a second common manifold which returns the refrigerant from all the partitions.

Another purpose is to emp oy means whereby pre-cooled convective liquid can be pumped into the common manifold feed line when the invention is applied to a car and the car, truck or other conveyance is in position.

Another purpose is to employ a series of hinged doors or partitions which lie flat against the sides of the car or enclosure when not in use.

Another purpose is to employ hinged doors carrying refrigerant that are movable longitudinally in the car or container.

Another purpose is to maintain a refrigerated state within the car while it is being loaded.

Another purpose is to be able to restore a lower temperature to the articles after they are loaded in the conveyance.

Another purpose is to provide a means of loading the car at atmospheric temperature.

Another purpose is to provide an improved shipping assembly adaptable for shipping refrigerated materials in railroad cars, trucks, airplanes, ships and the like.

Other purposes will appear from time to time i in the course of the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein: p 1

Fig. 5 is a vertical section of Fig. 3 taken on the line 5-5 of Fig. 3, with parts in elevation; and

Fig. 6 is a perspective view from above with outside walls eliminated.

Like parts are indicated, by like symbols hrou h ut the ne icaiionand dr wings. v

Referring to the drawings, in Fig. 1, I illustrate my invention applied to a freight car with the outer walls indicated as I and the inner walls indicated as 2 with the insulation 3 between them. The inner walls 2 have the doors 4 attached by a hinged means. The doors 4 are illustrated as double sheets of metal with the tubes 5 between them to carry the precooled convective liquid through a circuitous route to the bottom of the door. should be understood that this means of refrigeration and door construction might be varied.

In the left half of Fig. 1, the doors are shown in a closed position. In the right half of the same drawing, the doors are shown in an open position, lying flat against the sides of the car, and completely out of the way while the car is front view of the hinge in conjunction with the.

door and the wall when the door is in a closed position and the refrigerant is supplied from manifold 8 to tube 9 which is preferably formed of a metal flexible member 9a to allow adjustment of the doors 4 backward or forward along the container wall. Attached to the side wall by means of a track 30 is a hinge member 3| which cradles a cone shaped member 32. The cone 32 is attached to the door 4 by means of a crown 33. Within this cone shaped member or cook 32 is a passage 34 which forms with tube 9 an open circuit for the refrigerant when the door is in a closed position.

The track 39 is fastened to side wall 2 and holds firmly the hinge member 3i. An adjustable tongue 35 and slot arrangement 35 is located between the track 3!] and the hinge member 3| so that the doors 4 can be adjusted forward or backward, along the wall, to conform with the size of the load.

Figures 3 and 5 show respectively a top and front view of the hinge in conjunction with the door and side walls when the door is in an open position and the refrigerant circuit is closed. As the door 4 is swung open the cook 32 turns with the door while the hinge or cradle member 3| remains stationary. Thus the passage 34 does not connect with tube 9. Instead the passage 34 is shut off at 3412 by the wall of the cradle 3!. Likewise the tube 9 is shut off at 9b by the wall of the cock 32. Thus the pre-cooled connective liquid is locked in the passage 34 and tube 8 and flow to or from the door or partition is thus cut off.

This device of a track holding a cradle which supports a cock is employed at the top and bottom outer. edge of, each door. The refrigerant may be of metal and However, it i perature.

the sides'and doors, an even temperature is main-- path Within" the door drains off through the.

lower device near the bottom of the door.

The pro-cooled convective liquid is supphed through gflcommon manifold 8 which carries the a liquid to all the doors by means of the individual sub-passages 9. v

Pro-cooled convective fluid can be supplied at either end of the freight car, or other container, through the passage II to the manifold 8 and after it has flowed through the tubes of the doors can be carried off from the return manifold It through the passage 12 at either end of the car, This can be done by a regular refrigeration means and, in most cases ,will be done at the place where thefreight car or container is loaded with frozen food. Thus as each section is packed with frozenarticles the door is adiusted to position and closed and fastened, immediately,

pro-cooled convective fluid flows through the tubes of'the door. The fluid also flows through the two stationary end wall plates 2!. If the doors and the inside walls 2 are formed ofmetal they act as heat diffuser means and maintain an even temperature throughout the freight car. Itis to be understood that while I illustrate my perature if they have accumulated some heat during the loading' It also provides means whereby the articles packed can bekept in a frozen state while the freight car door is open. And it allows the loading to take place under atmospheric conditions, thus eliminating the necessity for the men loading the car to wear specialclothing', in View of the fact that only'the packed or loaded part of the car or container is subject to full refrigeration.

The refrigerant may be, and usually is fed at the place of loading, but it could be done at.

' any desirable or convenient place. There may be.

invention as used in a freight car, it .can also be adapted toa truck, a rplane or ship. '7

It will be understood'that whereas there has been "described and shown. a practical and operative device, nevertheless many changes may be madein size, shape, number and dis osition of parts without departing from the spirit of the invention. therefore the descr ption and drawings are to be taken as in a broad-sensepillustrative or diagrammatic The invention is not, limited to a vehicle and maybe employedin any type of container. The.

container maybe stationary or may be movable and maybe mounted upon ormayfform a part of any typeof vehicle.

tion. .Many materials may be used without departing from the spirit of. the invent on. 7 The invention is not limited to any particular valve arrangement. Generally sneaking any valve which .can be-positioned between the container and part tion-and which in onepositionepermits;

The use and operation of the invention are as follows:

In. shi ping pre-cooled or frozen articles it is necessary toahave ameans whereby the articles can remain in the car for a long period, such as thirty days without adangerous change in tem- By using a heat' conducti've metal for tained throughout the car.

Before the car is loaded, the series of' doors or'partitions are o en and in a flat pos tion along the side walls of the car or other container. As eachsectiorr-of thecar is loadedthe double doors are closed snugly upon the frozen articles and locked in position. In this position the-cock opens the: circuit and allows the preacooled. convective fluid to flow from the supply manifold 8 into the 7 tubes .5 of'the doors;

This cock connection is, preferably, identical on both the outer sides of The invention is not. limitedto. any particular materials or construcinstances whenit will be desirable to refrigerate the car again before it reaches its desination. This can be done without many way disturbing the shipment in the car by simply stopping at one'of the refrigerant supplydepots.
