To all whom t may concern.' l

Be it known that l, ARTHUR R. BAnNnrr, citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a certain new and useful Improvement in Refrigerators, of which the following is a specification.

My invention relates to improvements in refrigerators, and the object of my inven-` tion is to provide a refrigerator which shall be adapted for household use and within whose interior space the temperature may be maintained at a much lower degree than the temperature of the external atmosphere without the employment of ice or artificial chemical agents, whereby articles of food,y

if disposed within said refrigerator, may be kept cooler than said external atmosphere,

li accomplish this object by devicesillustrated in the accompanying drawings wherein Figure 1 is a view of a structure embodying my invention, in vertical section on brokenl line m, m of Fig. 3; Fig. 2 is a viewof the same in vertical section on broken line y, je/ of Fig. 1; Fig. 3 is a view of the same in horizontal section on broken line' e, z of Fig. 1; Fig. 4 is a view of'another structure, embodying a modified form of parts of my invention, on broken line a, a of Fig. 6; Fig. 5 is a view of the same in vertical section on broken line b of Fig. 4; Fig. 6 is a view of the same inhorizontal section on broken line c, c of Fig. 4; and Fig. 7 is a view in perspective of a detail of the same. Referring to the drawings, throughout which like reference numerals indicate like parts, 8 designates an inclosing case whose interior space is divided-intoV two chambers 9 and ,10by a vertical partition 11 that is lso disposed to extend Ibetween the bottom wall 12 and the top wall 13 of said case 8 that,

the chamber 10 is almostfour times as large as the chamber 9, said chamber 10 being adapted to serve as a receptacle for articles of food that are to be kept cool;

"Within the larger chamber 10 is a conduit 14 forwater, of rectangular cross-section, of such width as adapts it to extend throughT out the distance betweenthe vertical front wall 15 and the vertical back wall 16, and

of such length as adapts itvto extend from the lower end portion of the partition 11 to the upper end portion thereof in a staggered course between said partition 11 and the vertical side wall 17, whereby are formed three

horizontal shelves

18, 19 and 20, as

shown more clearly in Fig. 1, upon whichv shelves food may be stored.

The under wall, of that portion of the conduit `14 that formsthe horizontal shelf v 18 declines from the partition 11 to the vertical side wall 17 and the under wall of that heat, shall always have an inclined path through said conduit 14 from that point that is adjacent to the bottom end portion of the vertical side wall 17 to that point of it that is adjacent to the top end portion of the partition 11., The under wall of that portion of said conduit 14 that forms theY shelf 18 is declined from the partition 11 in order that the whole of said conduit 14 and its associated parts may be wholly emptied and drained, as may berequired, by turning the handle of a faucet 21 whose nipple is connected with said conduit 14 at a point adjacent to the bottom wall 12 to extend outwardly through the vertical side wall 17 as` shown.

In the lower portion of the chamber 9 are a plurality of headers 22 whose nipples extend through the partition 11 vvto connect with the lower end of the conduit 14, while in the top portion of said chamber9 is a like number of headers 23`whose nipples extend throught the partition 11v to connect with the upper end of said conduit 14in positions corresponding to the positions of the headers 22 inthe bottom'portion of the chamber 9.

Each of the headers 22 is provided with two upwardlyprojecting flanged sockets, as sockets 24, and each ofthe headers 23 is provided with two downwardly projecting flanged sockets 25,`and disposed to extend vertically between each of corresponding onesof the

sockets

22 and 23 is `a conduit` lof porous material, as conduits'26, all of said vertically disposed porous conduits 26 and the conduit 14. j

Extending downwardly from the chamber 9 through the bottom wall 12 are a plurality of air holes 27 `and extending upwardly from said chamber 9 through the top wall.13 are a plurality of other air holes 28, whereby air may enter the bottom of said chamber 9 to rise upwardly therethrough and flow outwardly from the top thereof or vice versa.

Upon the top wall 13 of the case 8, near the back wall 16 thereof, is a funnel '29 which is provided with a removable cover 30, the nippleof which funnel 29 projects downwardly through the top wall 13 to conn ect with the conduit 14, through which funnel 29 water may be poured in the oper-` ation of filling the conduit 14 and ciated porous conduits 26.

The vertical front wall 15, of the case 8, is provided with a door 31 which may be opened to gain access to the interior: to the larger chamber 10.

The conduit 14 and

headers

22 and 23 may the assobe made of sheet metal, as galvanized sheet iron, or they may be made of molded pottery as may be desired, and for some conditions of use they may be made of cast iron; but the vertically disposed conduits 26 must be made of porous material, as porous earthen ware, coarse vulcanized wood fiber, paper ber or the like, so that water may percolate through the walls thereof to moisten their .exterior surfaces.

In Figs. 4, 5, 6 and 7, I have illustrated a modified form of internal parts of a re' frigerator embodying my invention wherein the larger chamber 32 (which corresponds j lrefrigerator shown in Flgs. 4, 5 and 6 1s to the larger chamber' 10 of Figs. 1 and 3) is provided with a conduit made of an iron pipe 33 which is formed and disposed to eX- tend from the lower portion of the smaller chamber 34 (which corresponds to the smaller chamber 9 of Figs. 1 and 3) through a partitiorr35, thence adjacent to the vertica wall 36 in a decline to a point adjacent to the vertical side wall 37 where it connects with a T fitting 38, to one terminal of which is connected a draining faucet 39 (which corresponds to the faucet 21 of Figs. 1 and 3) vfrom which T fitting 38 said pipe 33 extends on an incline to stagger back and forth and upwardly adjacent to the vertical slde l wall 37, the vertical back wall 36 and the vmi vertical partitiony 35 to the top portion of the larger chamber 32 to a point adjacent to the partition 35 there to connect with a T fitting-.40, to one terminal of which is connected the nipple 41 which extends upwardly through the horizontal top'wall 42 to conneet with a funnel 43 (which corresponds tc the funnel 29 of Figs. 1 and 2), while the remaining terminal of the T fitting 40 connects with a nipple 44 which extends through the partition 35. into the smaller chamber 34.

Within the chamber 34, at the bottom portion thereof, is a header 45 to which is connected the bottom end of the iron vpipe 33,l

and which header 45 is provided. with a plurality of upwardly projecting sockets 46, while in the top portion of said smaller chamber 34 is a header 47 to which is con- .nected the nipple 44 and which is provided and vertical end wall 37 at different pointsk in elevation, and upon each pair of said rods is removably disposed a tray 53 of the form shown in Fig. 7, whose walls are perforated to form air passageways and one of whose sidewalls is disposed to serve as a shelf53,

as more clearly shown in Fig. 5, upon which4 front wall 54 is provided with a door 55 f' by which one may gain access to the inter1or of the larger chamber 32.

The smaller chamber 34, like the chamber 9 of Figs. l and 3, is provided with air holes 56 extending through both its top and bottom walls whereby air may flow through said chamber 34.

rllhe mode of operation of the refrigerator shown in Figs. 1, 2 and 3 and that of the exactly the same and such operation may be described as follows:

The` porous conduits in the smaller chamber and lthe non-porous 'conduit in the larger chamber are filled with water poured through the funnel on top of the structure, which water may then soak through the walls of the porous conduits in said smaller chamber to moisten the surfaces of said porous conduits whereupon the air that is free to circulate through said smaller chamber will `cause the moisture on the surfaces of' said porous conduits to evaporate, whlch process -wardly through said porous conduit again orous l per end of said non-porous' conduit andwith vwhich embodies an inclosing case whose interior space is dvidedby a vertical partition to form a lar er chamber and 'a smaller chamber and whic is further provided with la door in its front wall which opens into said larger chamber; a non-porous conduit for water, of oblong crosslsection, .disposed to extendfrom the bottom ortion of said smaller chamber through sai vertical partition into said larger chamber and across the Hoor of said lar er chamber, thence upwardly to the top o said larger chamber in a staggered course toA form a plurality of shelves therein, thence' through the top end portion of said partition into said smaller chamber; a conduit of porous material vertically disposed Vin said smaller chamber with its upper end connected with the upits lower end connected with the lower end of said non-porous conduit; a funnel disposed to connect with the upper portion of said non-porous conduit through which was ter may be poured to fill said non-porous conduit and its associated porous conduit; a faucet -connected to the lower portion of said non-porous conduit in a position to adapt it to be operated to drain all the water from said non-porous conduit and its associated porous conduit that may be contained therein; and passageways for air extending through both the'bottom wall and the top wall of said smaller chamber. y

2. A refrigerator of the class described comprising a casing having `a vertical partition dividin the same into two chambers, a double-wal .tortuous water passageway in one chamber, a porous water passageway in the other chamber and means arranged at the upper and lower ends of the last' named chamber forming communication beween the water passageways of each cham- 3. A refrigerator of the described class comprising a casing divided into two com partments, headers having vertically alined sockets positioned in the upper and lower ends of the casing, porous tubes positioned in the alined sockets, and a non-porous water receptacle communicating with the headers. f In witness whereof,r I hereunto subscribe my name this third day of January A..
