HARLANDW.WHITMORE ATTORNEYS Patented Nov. 7, 1950 BOTTLE COOLER Harland W. Whitmore, Kenosha, Wis., assignor to Motor Products Corporation, Detroit, Mich., a corporation of New York Application-June 28, 1948, SeriaLNo. 35,598 I 10 Claims. (01. 62-102 Ihe invention relates to apparatus for the cooling of bottles and has. for its object the obtaining of a construction in which the cooled bottles are readily accessible and easil removable from the cooler.
It is a further object to-obtain a, construction in which separate portions of the container are used; respectively, for the cooling of bottles after loading and for the storage of the cooled bottles for dispensing.
It is a further object to provide means for circulating the air within the cooling chamber to maintain a substantially uniform temperature in different portions thereof and for more rapidly absorbing heat from the bottles when first loaded.
It is a further object to provide means for the storage of the bottles in a plurality of tiers and for providing ready access to the lower as well as to the upper tiers.
With these and other advantageous features in view the invention consists in the construction as hereinafter set forth.
In the drawings:
Fig. 1 is a vertical central section partly in elevation through my improved cooler;
Fig. 2 is a plan view partly in horizontal section substantially on line 2--2, Fig. 1;
Fig. 3 is a vertical section corresponding to a portion of Fig. 1 showing one of the shelves in raised position;

Fig. 7 is a vertical section through a portion of the base section.
Fig. 8 is a side elevation of the blower.
While the instant invention relates more particularl to certain features of the cooler as above set forth, I shall briefly describe the complete apparatus. Generally the apparatus comprises a base section A which contains all of the mechanism, and a cabinet section B supported on the base section. The base section includes a base ring C of angle cross-section having a platform extending diametrically thereacross on which are mounted the motor, compressor, condenser and other elements of the perating mechanism. Rising from the ring C are posts C which, as shown, are of channel cross section having flanges C extending laterally from opposite sides and secured to the ring. At its upper end each post has a laterally inwardly extending portion C formed from the web of the channel, the sides being cut away to form a mitre joint as indicated at C Surrounding the posts, with the exception of the portion at the rear end of the platform, are' ring 2. sections C which are so fashioned as to form louvers for the free admission'of air-and attlie same time concealing the mechanism. These louver rings are attached to a plurality of bars 0' secured to and rising from the base ring C. The
base ring'is also provided with a pluralityof feet C spaced therearound and raising the ring casing and resting upon the bottom Dis a thermal insulating slab E. F is an inner cylindrical casing seated uponthe pad E and havingits cylindricali wall concentric with andspaced from the wall ofthe outer casing D. The casing F has helically wrapped thereabout a tube G forming the evaporator, which tube is preferably soldered or otherwise held in heat conducting contact with a wall of said casing F. The lower end of this helical tube is connected with an accumulator G which extends vertically adjacent to the wall of the casing F and-the upper end of the accumulator is connected to a suction tube G which is return bent to extend downward into the base 7 section through a sealing grummet D in the bottom Dof the outer casing. The upper end'of the helical tube G is connected to a cipallary tube G which is wound around the suction tube G and preferably soldered thereto, its lower end portion passingthrough the grummet D and being connected to the outlet fluid conduit H from the condenser H. The space between the concentric walls of the inner casing F and outer casing D is filled with thermo-insulating material E which extends up to near the top. Beads F and G form ledges on which is supported an annular thermo-insulator slab'E which is just below the top of said casings and is sealed thereto by mastic The top of the inner casing F is closed by a pair of lids I, which are mounted in a ring structure J. The latter has a depending flange J secured to the upper end portion of the casing D. There is also a ring section J preferably formed of rubber, which overlaps the casing F and is of angle cross-section with its horizontal flange centrally split part way therethroughto receive a. flange J 3 of a metallic ring J 4 which lines the rubber ring J Thus the rubber ring J forms thermalinsulation between the casing F and the ring J. The upper face J of the ring J formsa resilient seat for the lids I. These lids are of semicircularform and their inner straight edges are connected-by ahinge member I which at its oppositeends is pivotally supported on upwardly extendin bracket members I secured to the ring J on diametrically opposite sides thereof. The arrangement is such that either or both of the the inner casingF.
The height of the inner casing F is suificient to receive a plurality of tiers of bottles and as shown there are two tiers. The upper tier is supported by hinged shelf sections K which also are substantially semi-cylindrical but with a narrow stationary shelf section K therebetween'. Theshelf K is supported upon brackets K secured to the casing F, which brackets have a segmental flange K fitting the casing, a horizontal flange K an inner vertical flange K and a horizontal flange K together forming a substantiall .Z -:shaped cross-section. The shelf K is directly attached to the flange K The pivot pins K of the shelves K engage bearings in'the flange K and clip members K serve to hold the pivots normally in engagement with said bearings.
. The shelf K is centrally cut away for the passage of a blower casing member L, which latter is rigidly secured to and supported by said shelf member. A rotary fan 1.. is arranged within the casing L and is driven by a motor mounted on the casing so as to withdraw air from the space below the shelves and discharge it upward. A stack member L extends above the shelf K and has at its upper end a cap member L which defleets the blown air laterally, or toward the surrounding wall of the casing F, and also in a downwardly direction. The conductor cable L for the fan motor extends therefrom to pass downward through sealing grummets L and L which are in alignment with each other, respectively, in the bottom of the inner casing F and bottom D of the outer casing. This cable is then connected preferably in multiple with the motor for the compresser so that, as hereinafter explained, both motors will operate at the "same time or remain stationary.
With the construction as above described the bottles to be cooled may be stored within the easing F, one tier directly resting'upon the bottom of said casing and a second tier resting upon the shelves K and K. As both the shelves K and lids I are semi-circulanone lid section and one shelf section can be turned up into vertical position for the loading of one-half of the bottom tier and after return of the shelf section for loading the corresponding half of the upper tier. The other half of the casing may be loaded at a dif- 'ferent time and thus one-half may contain cooled bottlesg'while in the other half the bottles are being cooled. For this reason there are always cool bottles for dispensing. When the motor for the refrigerating apparatus in the base compartment is in operation the cylindrical wall of the inner casing F will be cooled to some predetermined low temperature by control means which is not a part of the instant invention. This, however, would not sufficiently cool all of the stored bottles and, therefore, the air within the casing is circulated. The direction of the current is first into the casing L centrally thereof, then upward through the stack L and laterally radially outward and inclining downward by the deflection of the cap L towards the cooled wall of the casing. This downward inclination of the air current is important as it avoids any tendency to blow the cold air out of the top of the casing when thejlid is open; The shelves K aremer f orated for the free circulation of air therethrough, as well as through the annular space surrounding the periphery of the shelves. The lids I are, however, substantially air tight so that there is only internal circulation of the air. The bottles will be sufiiciently spaced for passage of air therebetweenso that the temperature of air surrounding all of the bottles is substantially the same. It is desirable that the temperature within the casing should never drop low enough to freeze the content of the bottles or, on the other hand, to rise above a predetermined point. This may be accomplished by control means not a part of the instant invention, a thermostatic element M within the stack being effective to de-energize the motors at a predetermined minimum temperature of the air within the stack, while another thermostatic element such as a bulb M adjacent to the cooled wall of the casing F is effective to energize the motors at a predetermined maximum temperature of said wall. This minimum temperature is something above the freezing point of water so that the wall will be automatically defrosted during the portion of each cycle in which the motors are not in operation. The condensation is drained out from the casin through a conduit :N, which extends downward arough the bottoms of both inner and outer casings to a point outside of the louvers where it is provided with a removable cap N".
When bottles are introduced into or removed from the cabinet one of the closed lids may be raised to upright position, and if access to the lower tier is required the corresponding semicircular shelf can be also raised. The hinge axis of said shelf is out beyond the radiusof said stack but not beyond that of said cap. Therefore, the shelf is provided with an aperture to receivethe projecting portion of the cap so that the shelf will rest against said stack in stable upright position.
Where the cooler is used for the retail dispensing of the contents of the bottles, there is preferably provided an auxiliary casing O at tached to the front wall of the casing D and having near its upper end an opening for access to a bottle cap remover. The caps thus removed will drop down within the casing 0 into a removable container O at the lower end of said casing. This may be withdrawn and emptied "from time to time.
