BERNARD W. JEWELL BY ATTORNEYS Patented Dec. 8, 1953 AIR CONDITIONING UNIT AND APPARATUS FOR SHIPPING Bernard W. Jewell, Wichita, Kans., assignor to The O. A. Sutton Corporation, Inc., Wichita, Kans., a corporation of Kansas Application August 1, 1952, Serial No. 302,265

4 Claims. (Cl. 206-46) My present invention relates to means for restraining a heavy portion of a heavy appliance during shipment thereof, the invention being of particular utility in the shipment of window ledge air conditioning units. In appliances of this character there may be a heavy, motorized unit, such as the hermetically sealed motor-compressor unit commonly found in window ledge air conditioning units. The motor-compressor unit must be resiliently supported and otherwise isolated from the body of the appliance so as to eliminate or minimize the transmission of noises and vibrations therefrom to the casing of the unit when the appliance is in operation. On the other hand, the motorized portion of such an appliance must be firmly held in position during shipment of the unit or severe damage and possible destruction of the unit will result. Heretofore it has been the practice to provide special holding means, such as clamps, shipping bolts and other threaded fastening members, firmly to unite the motorized portion to the body of the unit during shipment. Such means are usually difficult of access and usually require the installer to remove access plates or a portion of the casing of the unit in order to remove or loosen the shipping hold-' down means. A primary object of the present invention is to eliminate such expensive, and difficult to operate, temporary holding means.

A further object of the present invention is to provide a shipping pallet for an air conditioning unit or equivalent appliance, which pallet is firmly attached to a portion of the unit during shipment, the unit and the pallet being cooperatively related to provide means for restraining the motorized portion of the unit, such as the hermetically sealed compressor thereof, against movement during shipment, and the unit being so arranged that it is ready for immediate operation when the shipping pallet is separated'therefrom.

Another object of the present invention is to reduce the ultimate cost of appliances of the character described by providing means for safe transit of the unit, and which means is of economical construction.

The objects and advantages of the present invention will be more readily understood from inspection of the accompanying drawings taken in connection with the following specification, and wherein the present invention isillustrated in the combination of an air conditioning unit and its shipping container.

In the drawings,

.Fig. 1 is a partially schematic representation of an air conditioning unit, having the present in- 4 Z vention associated therewith and illustrated in complete detail;

Fig. 2 is a plan view, on an enlarged scale, of a portion of the floor of the unit illustrated in Fig. 1 and associated portions of a shipping pallet constructed in accordance with the present invention; and

Fig. 3 is a detail, on an enlarged scale, taken substantially along line 3-3 of Fig; 2.

An appliance comprising a window ledge-air conditioning unit is illustrated in Fig. 1, the appliance comprising a housing l0 including'a bottom wall I l. The housing is subdivided by a vertical partition l2 into a condenser compartment I3 and an evaporator compartment I4. A hermetically sealed motor-compressor unit [5 is mounted in the condensing compartment, the

unit l5 being connected in refrigerant flow relationship with a condenser I6 closing one end of the condenser compartment and an evaporator I1 mounted in the evaporator compartment; The evaporator compartment is divided by a horizontal partition I8 on which is mounted blower means H! for withdrawing air from the room to be cooled through a room air inlet opening 20 and forcing the same through the evaporator I1 and into the room through the room air outlet opening 2|. A condenser blower 22 is mounted in the condenser compartment and driven by a motor 23, there beingappropriate shroud means (not shown) whereby airmay be caused to enter a' portion of the condenser from the outside space, flow in cooling relationship to the motor-compressor unit I 5, and be ejected back into the outside space through another portion of' the condenser l6. Refrigerant compressed by the motorcompressor unit is forced through a discharge tube 24 into the condenser l6 where it is cooled and liquified. The hot liquid refrigerant travels through a liquid line 25, an expanding member such as expansion valve 26 and supply tube 21 to the evaporator il in which it expands to cool the,

air being forced therethrough by the blower l9. The expanded refrigerant returns to the motorcompressor unit I5 through suction tube 28. The discharge line 24 and suction tube 28 are provided with vibration dampening means such as the large loops illustrated, whereby the motorcompressor unit I5 may vibrate to a large extent without transmitting such vibrations to the easing or other parts of the appliance. Moisture which is condensed from the air to be cooledis collected in a condensate pan 29 beneath the" evaporator I1 and is transmitted by gravity through a run-off tube 30 to a pan 3! in which ing arms which are weldedto arid'proje'ctb 3 wardly from the bottom of the motorized'u'n t.

Each of the arms 35 is provided with a central. opening 36 at its outer end inwhich is positioned;-

a rubber grommet 31 having a large flange .atits 4 speot to the resilient feet and associated mem-- bers that the weight of the unit is lifted from the springs and the flange of the gasket 31 is compressed between the arm 35 and the washer 38 when the bolts 58 are drawn tight. The mator-compressor unit is thereby held in firm association with the-shipping pallet and damage of the fame s, thus, prevented during shipment. When the unit is to be installed the shipping bolts 5% are removed, whereupon the weight of the motpr coi r rpres sor ui ri i I5 is transmitted to the s c 45 and the appliance is immediately in condition for operating. It is to be noted that no special toolsor. holding fixtures are required.
