Description
This invention relates to a device for cooling drinking water generally and more particularly to a receptacle having a cooling jacket. The device is adapted for mounting upon tripod stands now in common use for supporting water containers and associated cooling means and may be designed to receive the neck of a bottle, the latter serving as the water supply container.
Heretofore, it has been current practice to mount an olla of porous ceramic material upon a tripod stand. A water bottle is inverted and the neck inserted in an opening in the olla, water being withdrawn from the olla. The olla sweats and evaporation from its surface causes refrigeration of the water therein. Such ollas are exposed to the ambient atmosphere and are dependent upon the natural air movement for their refrigerating effect. They are fragile and subject to breakage. Germ life and vegetation become embedded in the pores, decay, and cause contamination which detrimentally ef- Frequent quired to maintain the ollas sanitary. It is an object of this invention to provide a refrigerating receptacle wherein all or any of the above mentioned and other attendant disadvantages well known to those skilled in the art are overcome and having any or all of the following features A refrigerating receptacle of the character described which has a shell of non-fragile material thereby protecting it from breakage due to extraneous forces; a device as above characterized having no refrigerating mechanism; details of structure wherein there is a cooling jacket surrounding the water container of the receptaclc and through which a draft of air may be induced; a cooling jacket having a wick coat to which water is supplied by capillary attraction and which water is subject to evaporation to effect refrigeration and whereby a non-fragile water container may be used; a water container wall impermeable to the passage of germ life or vegetation; and details of structure whereby a compact, efiicient and simple cooling device is obtained.
These objects are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:
Fig. 1 is an elevation, partly in section, of the device with a fragment of a water bottle shown; and Fig. 2 is a perspective View of the device.
The invention may be carried into practice by employing a non-porous drinking water vessel 5 such as of enameled metal having a mouth with a rounded lip 6 for re ceiving the neck of a water bottle 7. An outer shell 8 surrounds the vessel and extends below the bottom of the latter being formed with an annular drain reservoir or chamber 9. A shoulder 10 is provided in the shell 8 for the shell to restupon the ring 11 of a tripod stand of the usual construction. Cross members 12 extend across the shell and rest upon the ledge formed therein for supporting the vessel 5. The shell Sis spaced from the vessel 5 so as to provide an annular cooling jacket open at the top as indicated by 13 and communicating with the central opening 14 formed in the drain reservoir. The valve tap 15 is connected to the vessel 5 and serves for withdrawal of water from' the vessel, and is provided with a drip hole 15a whereby water may drip t0 the drain reservoir 9. An overflow pipe 16'communicates with the drain reservoir and has its discharge located in the hole 14 so that water will be maintained at a constant level in the reservoir and any surplus will be drained by pipe 16 into a suitable receptacle mounted on the tripod below the pipe and not shown. I
' A coat or envelope 17 of wick-like capillary material such as a flax canvas covers the side and bottom of' the vessel. It is shown attached to the vessel by clamping wires 18. This coat has a skirt 19 which depends from the vessel and hangs into the drain reservoir. The skirt is provided with openings 20 for the circulation of air. To aid the dispersion of water over the coat, a tube 21 is connected to the valve tap 15 and extended upward and around the container as indicated by 22. This tube is locatedw below the normal water levelin the con cooled. drain water in the dram reservoir as evapoin I) tainer and is provided with perforations at 22 to supply water to the coat, which water spreads over the coat by capillary attraction.
In the operation of the device, the drain 5 reservoir 9 fills with water supplied through drip hole a, the level being maintained at theovertlow pipe 16. The skirt 19 being immersed in the water, the envelope will be wetted. WVetting of the envelope is aided by ring 22. Evaporation will then occur jacket so that in a closed room the device would function with the same advantage when in a natural moving current of air. All sides, except the top of the vessel, are The drip hole 15a replenishes the ration occurs. Thus, stagnation is eliminated since both air and water are both automatlcally changing. The top of shell 8 1s formed with a drip lip 23 so that any con-- densedmoisture will run down the lip and onto the canvas jacket. The vessel and shell may be made of material impervious to water, non-fragile and not subject to deterioration, nor serving as a bed for germ life or vegetation. The parts may be easily assembled and disassembled for servicing and change of the canvas jacket. The etliciency of refrigeration is increased by reason of the annular flue between walls 8 and 5.
What I claim is 1. In a cooler, a vessel, a shell spaced from and surrounding the side of said vessel to provide a cooling jacket open at the top and bottom to form a flue for passage of air, said shell having a drip lip for condensate at the top, said shell having an annular reservoir at its lower end with a hole at the center, and a coat of wick material wrapped about the side and bottom of said vessel and having a skirt with vent holes and depending into said reservoir whereby to maintain said coat saturated and subject to evaporation.
2. In a cooler, a vessel, a shell spaced from and surrounding the side of said vessel to provide a cooling jacket open at the top and bottom to form a flue for passage of air, said shell having an inturned drip lip for condensate at its top, an annular water reservoir formed at the lower end of said shell with a hole at the center, a supporting ledge formed about said shell,,means at said ledge to support said vessel, and a coat of wick material wrapped about the side and bottom of said vessel and having a skirt with vent holes and depending into said reservoir whereby to maintain said coat saturated and subject to evaporation.
3. In a cooler, a vessel, a shell spaced from and surrounding the side of said vessel to provide a cooling acket open at the top and bottom to form a flue for passage of air, said shell having an inturned drip lip for condensate at its top, an annular water reservoir formed at the lower end of said shell with a hole at the center, a supporting ledge formed about said shell, cross members resting in said shell on said ledge and supporting said vessel, and a coat of wick material wrapped about the side and bottom of said vessel and having a skirt with vent holes and depending into said reservoir whereby to maintain said coat saturated and subject to evaporation.
4. In a water cooler, a vessel having a faucet fitting adjacent its bottom for withdrawal of water, a shell spaced from and surrounding the side wall of said vessel to provide a cooling acket open at the top and,
bottom to form a flue for passage of air, a water reservoir at the lower end of and ranging about said shell, said fitting being disposed above said reservoir and disposed to drip water into said reservoir and an envelope of capillary material surrounding said side wall and depending into said reservoir whereby to maintain said envelope saturated and subject to evaporation.
In witness that I claim the foregoing I have hereunto subscribed my name this 28rd day of December, 1930.
