WITNESSES: INVENTOR Patented May 4, 1937 PATENT OFFICE 2,079,238 METHOD or snrrrme asrn'reaas'rmo APPARAT John H. Ashbaugh, Springfield, Mass, assignor to Westinghouse Electric & Manufacturing Company, East Pittsburgh, la., a corporation of Pennsylvania Application October 5, 1935, Serial No. 43,647 Renewed September 11, 1936 14 Claims. (cries-36v) This invention relates to the art of shipping refrigerating or similar apparatus in vehicles and has for an object to provide an improved method and apparatus for shipping such apparatus.

A further object of the invention is to so arrange the apparatus in shipment that a maximum number may be transported in a conventional vehicle without the necessity of crating the apparatus.

A still further object of the invention is to provide improved method of transporting refrigerating apparatus havingan evaporating element and a condensing element which are fitted after shipment, into respective spaced openings in a cabinet wherein the elements are maintained during shipment in such spaced relation that unitary insertion thereof into the cabinet is afforded. These and other objects are effected by my invention, as will be apparent from the description and claims taken in connection with the accompanying drawings in which:

Figs. 1 and 2, are, respectively, rear and side elevations of a refrigerating unit arranged for shipment in a vehicle;

Fig. 3 is a perspective view of an improved, shiiging rack for the apparatus shown in Figs. 1

Fig. 4 is a sectional view of a refrigerator cabinet having the refrigerating unit inserted therein and prior to the disengagement of the shipping rack from theunit;

Figs. 5 and 6 are, respectively, transverse and longitudinal sectionalviews taken through a boxcar and illustrating my improved method of arranging the refrigerator units therein; and,

Fig. 7 is a transverse sectional view of a car showing a modified arrangement of the units therein.

Referring'now to Figs. 1, 2 and 4, I disclose a refrigerating unit, indicated generallyby the reference numeral l0, which is to be shipped to a distant point for assembly in a cabinet N (Fig. 4). The unit In is of the type disclosed and claimed in the copending application of J. H.

-' Ashbaugh, Serial No. 43,162, filed October 2, 1935,

and assigned to the Westinghouse Electric 8; Manufacturing Company, but it will be under. stood that this type of refrigerating unit is shown by way of example and that other forms of refrigerating. units or similar apparatus may be transported in accordance with my invention.

The refrigerating unit lflincludes an evaporator element l2 and a. condensing element l3 which are spaced apart and which are arranged, respectively, for insertion in the compartments to the cabinet- II by means of screws 243.

I4 and [5 of the cabinet ll. See Fig. 4'. Open-. ings l6 and [1 are formed, respectively, in a wall member ll! of the cabinet I l through which the elements l2 and I3 are inserted.

The evaporator element may include a closure plate I!) which is attached to the back of the cable net wall l8 by screws 2| and which supports one end of the evaporator l2 by means of a bracket 22. Flexible conduits 23 and 24 provide for the flow of refrigerant between the condensing element l3 and the evaporator l2. It will be apparent that, when the unit It) is assembled in the cabinet II, the evaporator l2 and condensing element i3 are independently supported by different portions of they cabinet, and, that the flexible connecting conduits 2,3 and 24 function only as refrigerant conductors and in, no manner provide a rigid support for any part of the unit.

The evaporator I2 may be provided at its front end with supporting lugs 24A which are secured The condensing element may include a motor driven compressor (not shown) which is enclosed by a casing 25 having cooling fins 26 and a condenser 21. The casing 25 and condenser 21 are supported by a platform 28 which, when. the unit is assembled in the cabinet, rests upon a bottom wall 29 of the cabinet II. The end of the casing is closed by a cover 3| having upturned flanges which are welded within the casing to 'profide a flangestructure, indicated at 32 in Fig. 2.

In order to facilitate the storage, handling and shipping of the unit I0, I provide a rackstructure 33, to which the unit Ill may-be attached in such manner, that a number of units and their racks may be compactly stored within a vehicle such. as, for example, a railway freight car. Furthermore, the method of attachment to the rack facilitates the assembly of the unit to the cabinet l I after shipment, as described hereinafter.

The rack 33 may include a rectangular angle iron frame 34 having guide clips 35 secured thereto, preferably, at each corner. A pair of brackets 36. may be fixed to the frame 34 for supporting the 3 evaporator element i2 during shipment,

which brackets 36 are provided with bolt holes 31.

The front end of the evaporator l2 may be supported, during shipment, by a hinged bracket 38,

. pivoted at 33 to the frame 34, and including bolt holes 4|. A plate 42 may be fixed to the frame 34 for attaching the condensing element l3 thereto.

In attaching the unit III- to the rack 33 for handling and shipment, the ,closure plate I9 is secured to the brackets 36 by means of the bolts 2| as shown best in Fig. 1. The hinged bracket 38 may be moved to engage the lugs 24A of the evaporator I2 and secured thereto by means of the tap screw 2413. The condensing element I3 is secured to the plate 42 by means of the hook bolts 44 which are hooked in any convenient manner to a portion of the element I3, such as, for example, the cooling fins 26. The hook bolts project through the holes 43 in the plate 42 and are drawn tight by the nuts 45. Proper positioning of the condensing element I3 on the rack may be obtained by providing an annular flange 46 on the plate 42; which flange 46 fits in telescopic relation, within the flange 32 of the casing 25.

Reference will now be had to Figs. 5 and 6 in which I disclose a conventional box car 48 equipped with a plurality of pairs of rails 49 for receiving the racks 33 and the units carried thereby. The rails 49 extend longitudinally of the 'car 48 from adjacent the center door opening thereof, toward each end of the car. The frame 34 rests on the rails with the guide clips 35 extending beneath the rail. In loading, the racks 33 are inserted on the ends of the rails adjacent the car doorand are slid toward the end of the car, adjacent racks being in engagement. When completely loaded, the plurality of tiers of racks 33 fill the car except for the portion of the car adjacent the center door. It is necessary that this portion of the car be available for the insertion of the racks on the rails and for the removal of the racks therefrom. After all racks and units are in place the space between the car doors may be utilized for shipment of other merchandise or a removable frame structure loaded with additional racks and units may be rolled into this space.

Longitudinal movement of the racks 33 upon the rails during transit may be prevented in any suitable manner such as, for example, by pins 5i which are inserted through openings in the rails 49 and which are engaged by the clips 35. A pin 5| may be employed at each end of each rail 49 for resisting the thrust of a row of racks, or preferably, a number of pins 5| may be employed at intervals along the rails, so that the thrust of only a few units is carried thereby.

In Fig. 7, I have shown a railway car having pairs of rails 52 which are spaced vertically instead of horizontally as in the prior embodiment. The racks are carried by the rails in the same manner as in the prior embodiment except that they are vertically disposed with the weight of the rack and units carried by the lower clips 35. In this embodiment the apparatus being transported is in its normal operating position which may be necessary with some apparatus.

When the car has arrived at its destination the racks and units are removed therefrom for assembly in the cabinets. The movable bracket 33 is first detached from the lugs 24A by removing the screws 24B and the bracket 38 is moved to a vertical position as shown in Fig. 4. As the evaporator element I2 and the condensing element which hold the closure l9 to the brackets 36 may then be removed. The hook bolts 44 are removed from the fins 26 and from the rack 33 by removing the nuts 45. The rack 33 is now disengaged from the refrigerating unit and may be removed and delivered to the car for its return journey and further use in transporting other units. sure to the brackets 36 may then be driven in the cabinet through the remaining holes in the closure I9. The screws 24B which have been removed from the bracket 38 may be employed for attaching the lugs 24A of the evaporator to the top of the compartment I4. The method of assembling the refrigerating unit III to the cabinet II is disclosed and claimed in the copending application of W. B. Anderson and E. E. Grover, Serial No. 48,814 filed November 8, 1935, and assigned to the Westinghouse Electric and Manufacturing Company. v

The racks and the attached units may be stored in a warehouse after unloading by providing rails in the warehouse arranged in a similar manner to the arrangement in the car. The units may be removed from the warehouse for assembly in cabinets as needed.

From the foregoing, it will be apparent that I have provided an improved method of storing,

transporting and handling apparatus of the kind described wherein packing or crating is unnecessary and wherein the number of units transported is of ahigh value. Furthermore, I have provided shipping equipment which may be employed to facilitate assembly of the transported apparatus with other apparatus at its destination. 1

I have eliminated the expense of providing crates for the apparatus being shipped which are usually discarded at the destination, being unfit for further use. My improved rack may be employed over and over again for carrying the apparatus during shipment and for facilitating art or as are specifically set forth in the appended claims. I
