Be it known that I, V@Anonimi S. -MooR n,' a citizen of the United States, residing -in the city and countyof San "Franciscoand- State of California, have invented a new and usefulk Improvement in a Cooler, of

which the following is a specification'v My invention relates yto yimprovements 1u Vcooling devices wherein a container, ar.- ranged to receive articles tobe cooled, .is provided with a double fabricwall arranged to contain a supply of liquid andadapted to permit the slow evaporation of saidgliquidv container may' whereby the interior Vof the The primary object of my invention is' to I provide an improved cooling device 'wheredevice which will be light and compact and still provide a relatively large capacity for'l by articles may be Vkept ycool withoutthe use of ice; 1 Another object isto provide an improved i device of the character described which will aEord increased area for the evaporation'of.

liquid and thereby increase the cooling effec-t obtained. f

A further object is to provide an irnproved device which will maintain an efficient operation forA long periods wit-hout attention, and which maybe easily vfilled with liquid when necessary,

vAnother object is to provide an improved articles to be cooled, and which may be tion.

proved device adapted to vbe collapsed and packed within a very small space, and which will'be eiiciently held i'n'shape when in'use.-

A still further object isto provide an improved construction which will -provide a strong, durable, and -eflicient' `cooler andY which may be manfactured at a low cost.

I accomplish theseand otherv objects by means of the improved device disclosed in' the drawings forming a part of the presentA specification wherein likecharacters of-reierence are used to designate similar parts throughout said specification and' drawings and in which, f Y j Fig. 1 is a perspective view oflmy improved cooler, parts being broken v awayLand shown in sectionfto disclose the construction and arrangement thereof.` Fig; 2 visa broken plan view of. the device, Fig. 3 is a broken Sectional 'detailtdrawn readily suspended in anyconvenient loca-j.

Av further' object to provide an im-v the container, the Vstitches 3 upon a larger scale and showingthe manner in which the cover and suspending-member Vare connected tothe upper edge of the conf tainer. f

Referring to the drawings my improved cooling device will be seen to consist of a vdouble wall foi'i'ned from a strip of canvas` or other suitable fabric doubled toV form inner andouter wall portions 1 and2 re-l spectively. The. doubled edge-of the fabric @strip forms the bottom edge of the container wall wherebyk the bottom edge .of the double f wall is fully closed. The ends of the doubled strip o fv fabric from which` the .wall vis formedare stitched together to forma continuous wall member, 'and' the inner and -outer wall portions are stitched together atl intervals by parallel rows of stitches 3, the portions of the `wall intervening between said rows of stitches 3 being spaced apart to form pockets 4 vertically disposed upon,

the outer side of the container wall. and open adjacent the top thereof.'

A shaping member 6, preferably anannular Wire hoop, is secured within the upper edge of thev inner wall portionl to shape the top of the container, said member preferably being` held in; position by folding v said vedge to v `the ing passed through the strips 9 as well as through the inner and outer wall portions 1 zand 2.as` above described. vTheportions ofthe v strips 9 extending between` adjacent rows offstitches 3 arev spaced awayfrom the'wall portion 1 to form the pockets 8.

A bottom member 12 is secured across the bottom of the container, said member being made of canvas, fabric, or -other suitable material, and havingja pluralityflof aper tures 13`formed therein to permit a'fcirculavtion of air within the container. The member 12 ispreferably stitched to the inner wall portion 1 as atf14.

` u The top, of thecontainerf Aisar ranged to be'jclosedV `by meansiof a.: -reiiiloifable cover" the upper edge 'of the wall portionoverthe 95 preferably be- 16 having apertures 17 formed therein to permit a circulation of air through the container. The cover is preferably made of canvas or other suitable fabric and is provided with a shaping element 18 secured Within the outer edge to lit over the top of the container whereby said cover' may be detachably secured upon the top ofthe container.

A strap 19 has its ends secured upon diametrically opposite sides of the inner *.vail portion adjacent the shaping'element (i to form a means suspending,` the container from any suitable support and for carrying the container from place to place. 'E' he strap 19 is of suficicnt length to permit the cover to be partially raised to give access to the interiorof the containerrivithout removing the container from a support from which it may be suspended by said strap 19.

ln operation my invention is as follows. yElie pockets l are filled Wit-h Water.V The fabric from which the container is constructed is of a nature adapted to retain the Water andvpermit only slow evaporation thereof. lVhen the pockets have been filled With Water the Water sofks through the fabric and is evaporated from both the inner and outer surface thereof. rihe evaporation of the Water absor is heat from the surrounding air in the Well known manner and as a result the interior of the container is cooled. The wat-er is evaporated from substantially the entire inner and outer area of the container Wall, the large area thus made effective causing a rapid and efiicient cooling` of the container. The pockets retain a considerable supply of Water so that it is only necessary to refill the pockets after a relatively longbr lapse of time. The apertures 13 and 17 formed in the bottom and cover respectively of the container permit a free circulation of air through the contain-er, and materially increase the ei'iiciency With Which the interior of the container is cooled.

The pockets 8 are provided Within the container to receive and support articles to be cooled. rlhus when the device is in use, articles of various natures can be inserted in the pockets and supported separately Within the cooled interior of the container in addition to such articles as may be placed directly upon the botten member 12, such articles being` cooled, and kept cool by the evaporation of Water from the `Wall'of the container. Xhile in use, the contents of the container are effectively protected by the cover 16.

The device is adapted for many purposes both.

for commercial and 'household uses vvhere it is desired to keep product-s cool Without the expenseof providingfice, and refrigerators to hold the same, or other refrigerating4 means. The device is particularly useful forli euse! hold purpose-s as L -"means of cooline4 andr keeping cool such products as butter, milk, fruit, and the like, suc-h as are ordinarily required to be kept in a refrigerator. In this connection, the device may be hung in any desired location and the products placed in any convenient manner in the pockets or upon the bottom member 12. The evaporation of the Water from the Walls of the container obtains a continuous cooling effect which effectively cools the interior of the container' and the articles placed therein, whereby such articles may be kept cool and fresh even in extremely Warm Weather. lf further cooling is required, a small quantity of ice placed within the container Will reduce the temperature slightly further, andv as the interior of the container is normally very cool, the ice melts very slowly and a small piece of ice will be caused to last arelatively long` time.

In addition to the commercial and household use mentioned, the device is particularly useful on outings or camping' trips. In

this connection, the fabric body of the device Y when empty may bey collapsed into a very kcompact object conveniently packed and transported, and easily placed in service when the destination is reached. If desired, the device may be carried in its extended container occupying only a small space and being readily suspended in an out of the Way location in o-r around a conveyance.

The specific form and arrangement ofthe device is of course subject to modification in various Ways Without departing from the spirit of my invention. I therefore do not Wish to restrict myself to the specific con-Y struction illustrated and described, but Wish to avail myself of all modifications which may fall Within t-he scope of the appended claims.

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