UNITED STA QOFFICE CHARLES A. MOORE, F ZEIDINA, MINNESOTA APP.l-LRA'NTS ITOR PRECOOLING LADING AT SHIPPING POINTS Application filed January 3, 1927. Serial No. 158,766.

My invention relates to improvements in apparatus particularly, though not exclu sively, for prescooling lading at shipping facilities for the temporary storage of produce under conditions wherein the field and animal heatmay be in process of extraction therefrom and whereby such process may continue during the loading of such produce in refrigerator cars.

conditioning and maintaining the atmospheric condition in the car not only before and after the loading and unloadingthereof;

but duringthe loading and unloadingfthereof, as well.

With the description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

An embodiment of my invention is illustrated in the drawings whereinFig. 1 is a vertical sectional view taken as on the line 1 -1 of Fig. 2; Fig. 2 is a horizontal sec- 7 tional' view taken as on the line 22 of Fig.

1; and Fig. 3 is a vertical sectional view taken as on the line 33 of Fig- 2.

' Reference being. had to the drawings, it

will be seen that a room structure A pro- -vides a room B with side walls 10 and 11, end walls 12 and a floor proper 13. Spaced above the floor proper is a false floor 14 formed of spaced slats or otherwise suitably constructed in perforated form to provide for the passage of air upwardly therethrough from the space -13 between said floor proper 13 and said false floor 14. Along the side wall 10 of the structure A are doorways 15 fitted with doors 16, said doorways providing access to the room B- through which produce may be taken into the room or removed therefrom. The op- It is also an object of my invention to provide means apart from a car for desirably posite side wall 11 is also formed with doorways 17 therein. These doorways l7 preferably are spaced apart a distance equal to the distance betweendoorways of coupled refrigerator cars, as at 18, and are disposed in elevation so that they will register, respectively, with the doorwaysof the refrigerator cars located alongside the building structure. For each doorway 17 I provide an accordion-like casing 19, one'end of each casing being secured to the outside of the side wall 11 about the margin of its respective doorway 17. Each casing 19. may be collapsed to take position closely against the outerysurface of the sidewall 11 and may be extended so that the outer end thereof will Tmeet the marginal portion, of the doorway of a refrigerator car registering with the doorway 17 about which the inner .end of the casing 19 is p1aced.- The usualgangplank 20 used to span the space bev tween the sill of the doorway 17 of the. foregoing andother objects in view, which will appear in the following building structure and the sill of the doorway of a car 18 rests within the expanded casing 19 slightly above the bottom thereof. A suitable door 21 of the sliding or otl1er type is provided for each doorway 17 in the side wall 11 of the structure A. lVhen the casing 19 for a particular doorway 17 is extended into position with the outer end thereof meeting the marginal portion of the doorway of the car, the respective door 21 is opened, and when the casing is collapsed, said door is closed. F s

From the foregoing it will be understood that the casings 19 provide enclosed gangways between the room B and cars 18 disposed alongside the room structure. And with such gangways provided between the room and cars it will be apparent that produce may be trucked into the cars from the room or from the cars'to the room without opening either room or cars to the outer atmosphere. Further, if there is any difference between the temperature of the. air within a car and the temperature of the air within the room, it will be comprehended that an equalization of temperatures be- 7 tween room and car will take place under gravity; for example, if the temperature to the upper portion of the room.

Within the room, I provide a device for affecting the temperature of the air therein. This device includes an upright casing C disposed transversel of the building structure and substantia y midway between ends ofthe room, saidcasing extending from a point beneath the floor proper 13 of the room structure A to the ceiling 22 thereof.

In the portion of the casing I arrange a horizontal partition 23 having perforations 24 therein or bein otherwise perforated to permit of the through. Extensions 25 of the u per portions vof the sides of the casing together with a bottom member 26 provide a com partment D at, the ceiling of the room,

-which compartment communicates through an openin ,27 in the end of said casing C with the air header E provided in said casing between the ceiling of the room and the horizontal perforated partition 23. At, either.

side of the casing G and adjacent the ceiling 22 of the room B isa duct 28, eachduct having an elongated opening 29 therein along the ceiling of the room and bein fitted with a damper 30 at the open end t ereof which communicates with said compartment D through an opening 31 in theside of the casing. Also communicating with this oomEartment D is 3, depending branch duct 32, t ted with a damper 33 and which communicates at the lower end. thereof with a long horizontal duct 34 passing abo ve the doorways 17 in the side wall 11 of the room structure A. Said ,long, horizontal duct 34 is provided at its lower side'with openings 35 (Fig. 3), one for eachdoor-f way 17. Each of these openin s 35' is an ranged along the upper edge 0 its respective doorway and extends from side to side thereof, and a curtain 36, provided for each opening, hangs from the duct 34, being se-. cured at its upper edge alon the transverse edges of the-opening 35 an inner longitudi'iial edge of said opening to form a flexible hood or depending extension of the duct 34 adjacent to the upper portion of its respective doorway'l7. Within the chamber'F, provided in the casing C beneath the horizontal partition 23, are coiled, pipes 37 for a temperature affecting me dium. Near the lower portion of said cas-.'

" .ing C and formed in the sides thereof are elongated openings 38, the same providing communications between said chamber -F and the space 13 at either side of the casing own flow of air there-f also. along the er air rising about produce stacked upon the false floor 14, the air from the s ace 13 between said floor proper 13 and alse floor 14 rises through the latter, all of said air, except as hereinafter noted, passing upwardly to the upper portion of the room, whence it is drawn into and through the duets 28 to the compartment D, whence it passes into the air header E and, thence, downwardly into the chamber F to begin its-cycle anew. With a car 18 and with a gangway enclosing casing 19 in place, as shown in Fig. 3, and with the damper 33 in the depending duct 34 open, a part of the cold air issuing through the false floor 14 at the bottom of the room B finds a read path into thecar through the lower portion of, said casing 19, such air thus entering 'the car and rising-along the warmer walls thereof and about any warmer produce within the car tinds a ready path from the car through theflupper portion of the gangway casing 19, thence through the upper portion of the doorway 17 to the hooded opening 35 of the duct 34, whence said air passes along said duct 34, thence upwardly through" the branch duct 32 to the compartment D where it meets the incoming air fromthe' ducts 28 and joins the same in completing "the cycle of movement.

In the event that a heated medium is contained within the pipes 37 .in the chamber ;F, the movement of air in the casing G, --.roomv B and car. 18 occurs reversely in the cycles aboveexplained.

To augment the movement of 'air under refrigeration, I employ within the chamber F of the'casing C, beneath the perforated partition 23 therein, a number of downwardl directed spray nozzles 39. A supply of re' rigerating liquid is contained inv the bottom of the casing C, in a tank G in which said liquid is stored with the surface thereof at alcvelslightly beneath the lower edges of the elongated openings 38 in the sides of the casing G. Within the tank G and submerged in the liquid therein are coiled from the tank G to the nozzles 39 and sprayed downward over the coiled pipes 37 and against the surface of the liquid in of the room structure Ais rovidediwith a gutter 44 at either side 0 the casing (3,.

Supplementing the action of the .spray nozzles 39in s'timulatin the flowof air in the casing 0, room B anfa car 18 is a blower 4:7 situated in the compartment D. When said blower idle, it does not-substantially.
