COOLER.

SPECIFICATION forming part of Letters Patent No. 424,125, dated March 25, 1890.

Application filed July 8, 1889. Serial No. 316,865. (No model.)

To all whom it may concern: and which are passed around the outer vessel Be it known that I, ALBERT lVICDONVELL, of and in contact with the fabric cover 0. These Selma, Fresno county, State of California, rolls have extension-flaps d, which hang down have invented an Improvement in Coolers; into the space a.

and I hereby declare the following to be afull, E is an outer belt or band of suitable fabclear, and exact description of the same. ric-such, for example, as duck or canvas My invention relates to that class of coolers which is strapped and fastened around the in which the evaporation of the Water is made exterior of the outer vessel A and presses to rapidly take place by exposing a consideragainst the rolls D. There is therefore formed 60 1o able surface of saturated fabric, whereby the between the outer vessel and the belt or strap temperature within the cooling-vessel is low- E an air-space F, which is made by the rolls ered. holding the strap or band out.

My invention consists in a suitable Vessel G is the roof for the outer vessel, formed for the water, having within it a vessel for the with swinging sides g, which are provided 65 I 5 material which is to be kept cool, covers of with covers g of a suitable absorbent matefabric or other suitable absorbent material rialsuch as bagging or other fabric-and fitted to the outside of the water-vessel and these covers have extension-flaps gi'which having end flaps falling over the edges of said 'hang down in the space a. The extensionvessel into the water, rolls of absorbent maflaps d of the rolls pass over the tops of the 70 2o terial or fabric passed around the exterior of swinging sides g and down into the space a the vessel and having extension-flaps projectwithin the vessel A, and thus the rolls are in ing into the water, an outer belt or band fitted contact with the fabric covers 9 of said sides. around the vessel outside of the rolls, whereby H is a fabric cover for the entire cooler, an air-space is formed between said belt or said cover being secured to theroof and hang- 75 band and the vessel, a suitable roof or top for ing down on each side of the cooler.

the vessel and absorbent coverings therefor, The operation of the cooler is as follows: and minor details of construction and ar- Water is placed in the outer vesselA, and rangement, all of which I shall hereinafter the inner vessel Bis set down into the water, fully describe, together with the objects of thelevel of which, however,is not high enough 80 my invention. to allow it to run over into the inner vessel.

Referring to the accompanying drawings In this inner vessel is placed the material to fora more complete explanation of my invenbe kept cool. The water fills the space a, and tion, Figure 1 is a vertical cross-section of my consequently the flaps c and d and g lie in cooler. Fig. 2 is a horizontal section on line the water in space a. The fabric coveringO 8 5 w m, Fig. 1. of the vessel A is first saturated with water,

A is the outer vessel, made of any suitable as are also the rolls D and the fabric cover g material. B is the inner or receiving vessel of the roof, and the extension-flaps, passing for containing the materials to be kept cool. down into the water, keep all these parts This inner vessel is enough smallerthan the thoroughly saturated as long as there is any 0 40 Outer one to leavea surrounding space a, and water left. The evaporation from these said inner vessel is held down in place by any saturated surfaces is great enough to reduce suitable 1neansas, for instance, by the the temperature within the vesselB and serve flanges a and the pivoted or swinging arm (t the purpose intended.

The outer surface of the vessel A is covered The rolls D have not only the function 95 with any suitable absorbent substance 0, prefheretofore described of holding the encirerably fabric of some kind, said absorbent cling belt or band E out to form the air-space material having flaps c, which bend over the F, but are also for the purpose of keeping the edge of the vessel and fit down into the space covering 0 wet longer than it otherwise would a between saidvessel and the inner vessel. remain wet. This they do by reason of not I00 D are rolls of absorbent materialsuch, for parting with their moisture as quickly as the example, as coarse muslin or other fabric covering 0, but hold it longer, and as they come in contact with the covering they keep it wet, and they also keep the roof-covering wet.

The circulation of air through the space F between the outer belt or band and vessel assists materially in the evaporation and in the general result.

In order to obtain access to the vessel, the hinged or swinging sides g of the roof are turned backwardly, thereby opening the top, or if water alone is desired from the inner vessel this may be drawn off by a siphon or any other suitable means.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. A cooler consisting of an outer vessel for containing water, an inner vessel for containing the material to be kept cool and sufficiently smaller than the outer vessel to leave a water-space around it, and a covering of fabric or other absorbent material about the exterior of the outer vessel and having extension-flaps turning over its edges into the water-space between the two vessels, substantially as described.

2. A cooler consisting of the outer vessel for containing water, the inner vessel for containing the material to be cooled and suiticientlysmaller than the outer vessel to leave a surrounding water-space, a covering for the outer vessel of fabric or other absorbent material, having extension-flaps passing over the edge of the outer vessel into the water-space, and the rolls of fabric or other absorbent material passing around the outer vessel and in contact with its covering, said rolls having extension-flaps passing down into the waterspace, substantially as described.

3. A cooler consisting of the outer vessel for containing water, an inner vessel for containing the material to be cooled and sulficiently smaller than the outer vessel to leave a surrounding water-space, acovering for the outer vessel of fabric or other absorbent material, having flaps extending down into the Water-space, rolls of fabric or other absorbent material passing around the outer vessel and in contact with its covering, said rolls having flaps extending down into the water-space, and an outer belt or band covering the rolls and outer vessel and forming a space for air between itself and the covering of said vessel, substantially as described.

4. In a cooler, the combination of the outer vessel for containing water, the inner vessel for containing the material to be cooled and sufliciently smaller to leave a water-space, a covering for said outer vessel of fabric or other absorbent material and having flaps extending down into the Water-space, a roof for said outer vessel having swinging sides, and a covering of fabric or other absorbent material for said sides and having flaps passing down into the water-space, substantially as described.

5. A cooler consisting of the outer vessel, the inner vessel, leaving a space between for the water, the absorbent or fabric covering 0 for the outer vessel having extensionflaps passing down into the water-space, the roof for the outer vessel having swinging sides, the absorbent or fabric covering for said swinging sides, having extension flaps passing down into the Water-space, and the rolls of fabric or other absorbent material passing around the outer vessel and roof and in contact with their coverings and having flaps extending down into the water-space, substantially as described.

6. A cooler consisting of the outer vessel, the inner vessel, leaving a water-space between them, the absorbent or fabric covering for the outer vessel, having flaps extending down into the water-space, the roof for the outer vessel having the swinging sides, the absorbent or fabric covering for said sides, having flaps extending down into the waterspaoe, the rolls of fabric or other absorbent material passing around the outer vessel and the roof and in contact with their coverings and having flaps extending down into the water space, and the outer belt or band around the outer vessel and rolls, forming the air-space F, substantially as described.

In witness whereof I have hereunto set my hand.

ALBERT MCDOWVELL.
