UNITED STATES JOSEPH A. WEIR, OF

MEMPHIS, TENNESSEE.

REFRIGERATOR.

Application filed April 26, 1921.

To all fr0/0m it may concern:

Be it known that I, JOSEPH A. Winn, a citizen of the United States, residing at Memphis, in the county of Shelby and State ofTennessee, useful Improvements in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to refrigerators and has for its object to produce a device of this character which will be simple in construction, comparatively inexpensive to manufacture, and more efficient in use than those heretofore proposed.

lVith these and other objects in view, the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification, in which like numerals designate like parts in all the views:

Figure l is a diagrammatic plan view of a refrigerator made in accordance with the present invention;

Fig. 2 is a front elevational view of the parts shown in Fig. l;

Fig. 3 is a plan view of the parts illustrated in Figs. l and 2 with the cover members thereof removed, showing the interior of the refrigerator;

Fig. 4 is a longitudinal, vertical sectional view taken approximately on the line 4-4 of Fig. l, looking in the direction of the arrows;

Fig. 5 is a fragmentary, longitudinal, vertical, sectional view taken approximately on the line 545 of Fig. 1; an

Fig. 6 is a transverse, vertical sectional view taken approximately on the line 6-6 of Fig. 1.

l indicates any suitable outer receptacle constructed of wood or other material and of any desired dimensions within which is fitted an inner receptacle 2 preferably of metal and spaced from said outer receptacle 1, to provide an air space 3 therebetween, which space 3 may, if desired, be filled with mineral wool, asbestos, charcoal, or other non-conducting or heat insulating material. The said inner receptacle 2 is provided with a bottom member 4 upon which rests one or Specification of Letters Pa tent.

more supporting members 5, of wood or other suitable material, which members 5 preferably take the form substantially as shown. Upon the said members 5 are mounted a plurality of ice receiving cans 6,7, and 8, preferably of liquid tight metal construction, which cans are adapted to be filled with a mixture of ice and salt. Each of the said ice receiving cans is provided with one or more outlets such as 9 located rather near the top of the said can, and associated with each of the said outlets is a drain pipe lO which may be secured to the wall of the ice cans in any suitable manner as by the strap mem ers 11, and which drain pipes lead through the top of the supporting members 5 to a drip water or brine receiving pan 12, preferably iocated below the said supporting members, as will be clear from the drawings.

Leading from each of the drip 19 are pipes 13 emptying into a common trough or receiving member 14, from which leads a final drain pipe 15 through the walls of the inner and outer receptacles 2 and 1 to the exterior of the refrigerator.

The device may be provided with any desired number of hinge-d doors or lids 16, for the purpose of permitting access to the interior, which lids may be suitably constructed and provided with heat insulating material similar to the body portion of the refrigerator, as will be readily apparent.

In use the ice receiving cans 6, 7, and 8 are filled with a mixture of broken ice and salt, and are then placed within the inner receptacle 2 resting upon the wooden supportingmembers 5 in the manner clearly indicated in Figs. 4, 5 and 6. The ice water pans 12 are placed in position beneath the supporting members 5 and any foodstuffs or other materials which it is desired to keep cool are introduced into the receptacle through the hinged top members 1G, as will be readily apparent.

It will be noted that by this construction employing the wooden supporting members, or racks 5, a free circulation of air is permit ted to pass at all times on all sides and under the ice receiving. cans 6, 7 and 8, and it has been proven under actual conditions that meat and other perishable articles can be kept from l2 to 14 days in good condition when stored in this manner. Furthermore, when the foodstuffs are removed they are always dry.

water pans By the location of the doors in the top of the refrigerator the warmer portion of the air within will always escape whenever one of the doors is opened and should there be no occasion to open these said doors, I have provided an auxiliary vent means 17 adapt-v further, due to the agitation of the waterv resulting from the flow from one pan to another, the eficiency of the apparatus is increased, for such agitation results in an increased absorption of the heat by the brine from the surrounding air. Y

I have found that under actual working conditions employing a box S feet long and i feet wide constructed and operated as above disclosed, that it is very easy to maintain a temperatureV of from 260 to 280 It., with from 100 to 150 pounds of ice daily. Also, that about 1200 pounds of meat may be stored in a box of this size and be kept in good condition Vat all times. Further, as will be readily apparent, the various ice receiving cans and ice water pans may be readily removed for cleansing both the cans as well as the box itself, leaving only the inner and outer receptacles, thus facilitating the cleaning of the latter to a very great extent.

It is obvious that .thoseskilled in the art may vary the details of construction, as

well as the arrangement of parts, without departing from the spirit of the invention, and therefore, I do not wish to be limited to the above disclosure except as may be required by the claims.

What VI claim is:

1. In a refrigerator the combination of a receptacle; a vent leading from the interior to the exterior ef said receptacle; upwardly opening closures in the top of said receptacle; a readily removable open container adapted to hold ice and salt mounted within said receptacle with its open end adjacent said closures; an outlet nearthe top of said container for the drip water; readily removable means for supporting said container out of contact with. the side and bottom walls of said receptacle, whereby a free flow of air is permitted on all sides of said conscribed.

tainer; a'readily removable drip water receiving pan within said receptacle adapted to receive the drip water from said outlet; a drain leading from said outlet to said pan; and connections kbetween said pan and the exterior of said receptacle adapted to convey said drip water -from said pan, substantially as described.

2. In a refrigerator the combination of a receptacle comprising inner and outen members secured in spaced relation; upwardly opening closures in the top of said receptacle; a plurality of readily removable open containers adapted to hold ice and salt mounted within said receptacle with their open ends in close proximity to said closures; readilyV removable means for supporting saidk containers out of contact with` a receptacle comprising inner and outer Y members secured in spaced relation, said space being filled with a heat insulating ma-V terial; a vent means leading from the interiorto the exterior of said receptacle; a plurality of readily removable containers within said receptacle adapted to contain ice and salt; readily removable members for supporting said containers out of contact with the side and bottomwalls of said receptacle, whereby a free flow of air is permitted on all sides of said containers; a pair of readily removable drip water receiving pans located within said receptacle beneath said supporting members; connections adapted to transfer drip-water from said containers to said receiving pans; a third readily removablD water receiving pan; connections between each of said first twopans and said third pan ;VV and a drain leading from said third pan, substantiallyas de whereof I aflix my signature.

In testimony i .rosari-r A. were.
