Application December 23, 1939, Serial NO. 310,812 1f claim.- (c1. sz-89) This invention relates to bottle coolers and has r its object to provide a new and improved de- `cooler wherein bottleswith beverage therein may be eillciently kept in -a` cooled condition without In the bottle coolers as now used, the bottles are water or a fan or mechanical air moving device of some kind is used to circulate the air in the cooler. l One of the objects of the present invention is to provide a dry bottle cooler which works effectively without any mechanical air moving device, such as a fan. `The invention has asa further object to provide-a bottle cooler which may be used either dry or with water in which the bottles are placed. further objects which are more particularly pointed out in the accompanying description.

Referring now to the drawings,

Like numerals refer to like parts throughout the several eures.

Referring now to the drawings, I have shown one form of bottle cooling device embodying the invention. In this construction there is a heat insulated receptacle, which consists of al bottom and upstanding sides and ends, in which .the bottles are received. The interior of the bottle cooler is preferably made of a metal receptacle i The exterior surface is preferably made from a metal receptacle 2 and the space between the two metal receptacles is lled with heat insulating material 3.

Within the receptacle i there are preferably provided two refrigerating members or evaporators d and 5 of any desired construction, but preferably of a thin plate construction, suspended in substantially parallel vertical planes, that is evaporators which ,are comparatively thin and made up of separated metal walls with means for showing the con- 'I'he invention has` Fig; 3 is a plan view of Fig. 1 with the cover re- I this descriptionfor use in cooling bottles water 'or other E rator 4 and its .associated wall.

these evaporators are above the. bottom of the the walls. These evaporators preferably have smooth or they may be made of the type asset out in my where the refrigerant when circulated back and forthv between 4the walls of the plates, makes direct contact with .the these walls form primary cooling surfaces.

These evaporators are suspended by any supporting means, so that there is a free space 6 between the evaporator 5 and its associated wall and a free space 1 between the' evaporeceptacle I so as to provide spaces 8 and 9 between the bottoms of the evaporators'and the 4 bottom of lthe cooler upon which the bottles to parallel to the evaporators.

closing. This is. particularly desirable whenv circulating a refrigerant back and forth between w be cooled rest. As herein shown the evaporators are supported by means of the brackets 4a and 5a which are connected to the evaporators and to the wall of the cooler.

Between the` evaporators space I0 in which the bottles ll to be cooled are located. The bottles are preferably stood up on their bottoms between the evaporators so as to be in a substantially vertical position substantially The cooler is provided with a top of any suitable kind. I prefer to form the top of two doors I2 and i3 pivoted or hinged at I4 so thateither can be moved alone. I also prefer to provide some means for preventing the doors from completely warm bottles are placed 1in the cooler. This result maybe secured in any desired manner, as by providing stops l5 and I6 against which the doors The evaporators may be connected to any source of refrigerant supply. I prefer, however, to provide a refrigerating apparatus arranged to form 'a part of the device and which is located in a receiving space I9 underneath the bottom of the receptacle l, at one end of the device. This space walls of the'plates sovthat.

The bottoms'A of is an open topped the

pipes

25 and 26, with an expansion valve 21,

'in any oi theusual ways.

When the device is in operation and the refrigerant circulating through the evaporators, the air on both sides of the evaporators is cooled and drops down. It will be noted that by this l construction both sides of both evaporators are in the bottom of space 9 t6 the central space I0 containing the Y bottles. 1 between the evaporator Wall is cooled and drops down and passes under the evaporator through space 8 into the central space `I0 where. the bottles are received. 'I'he air next tothe opposed faces of the evaporators is also cooled and drops where the bottles are received, so that both sides of each evaporator are used for cooling the central space I0 containing the bottles.

Some means is provided for automatically shutting down the motor when the temperature in the cooler reaches a predetermined point. 'As herein shown, there is provided a bulb 28 located between the two plates or

evaporators

4 and 5. This bulb is connected to the chamber 29 provided with a diaphragm 30 having an electrical contactA 3 l therewith, to which is. connected a conductor 32 which connects with the motor 23. There-is an electricalcontact 33 opposite the diaphragm, which is connected by a conductor 34 with one of the conductors 35 of the In the same way the airin the space 4 and its associated source ofelectric supply. The other conductor 36 of the source of electric'supply is connected by conductor 31 with the motor. When the temperature rises above a predetermined point, the diaphragm is moved to connect the contacts 3| and 33 so as to connect the motor 23'in circuit and cause it to operate the refrigerating apparatus. When the temperature falls below va predetermined point, the diaphragm 30 is moved so that contacts the circuit through the motor broken and the motor stopped. The size of the evaporators with relation to the size of the 'container and the lead of bottles in the container is such that the evaporators are defrosted, yet the desired temperature is maintained throughout the cycle, this desired temperature being the temperature the user wants, a preferable temperature being a temperature of about 38 degrees Fahrenheit.

down into the space I3 3| and 33 are disconnected and 'Ihe usual type of bulb 33 to controly the expansion valve 21 is provided. As shown, it is secured to the return lpipe to the compressor near the evaporator 5. Any laccumulation of water resulting from defrosting may be drained by removing the plug 39 from the aperture 40 the receptacle i. Guard strips II- are placed at each end ot the receptacle, near the top, to protect the pipes and bulb from injury when bottles are being loaded or unloaded.

In using the devicefthe bottles are placed in the space I0 between the evaporators I and i and the refrigerant circulated through the evaporators so as to cool them, the cool air from both sides of both evaporators dropping down and being discharged intothe space I0 between the evaporators, cold air thus surrounding the bottles and cooling them, the warm air passing up to the top of the bottle cooler. By means of this device the bottles can be quickly and effectively air cooled to any desired temperature without the use of water and without the use of any mechanica1 air moving device, as the evaporators by their location insure a proper circulation of the cold air around the bottles by thermosyphonic action, so as to provide a substantially uniformly cooled bottle receiving space between the evaporators.

I claim: A. bottle cooler comprising a heat insulated receptacle having a top and two separated evaporators having continuous imperforate side walls suspended in substantially vertical planes with a bottle receiving space between them open at the top, said evaporators spaced apart from the side walls and the bottom of the' receptacle, so as to provide an air space between each of the evaporators and its associated side wail closed at the sides and open at the top and bottom and between the bottoms of the evaporators and the bottom of the receptacle, the air between the evaporators and their associated side walls being cooled and brought into the bottle receiving space by thermosyphonic action, the bottles being inserted and removed through the open top ofthe bottle receiving space between the evaporators, a door for said open top and means for holding said door partially open so that warm air may escape while it is being cooled.
