' Application fue@ october 24 To all 'whom it may concern: Beit known that I, GEORGE M. WALKER, a l citizen of the United States, and a residentof l Lincoln, in the county of Lancaster-and State of Nebraska, have' inyentedafnew. and Imroved Refrigerator, of which the following 1s a full, clear, and exact description.

. This invention relates to certain-improve- -inents'in refrigerators, and more particularly to a special construction whereby the storage or provision compartments may be cooled i either by the continuous circulation of a rounding said compartments, or may ,.fbe cooled bythe use of -1ce,the drlp Water from ing drawings, forming apart of this specifiiigures, and in Whic i-.- Figure l is a front elevation of a refrigera-` tor constructed in accordance with my invention, and showing the door open and a por-. tion of the body-broken away; and Fig. 2 isa In my refrigerator I provide all the co1ne outside casing and cially for. the reception of ice. In-addition to the "ice compartment, there may be one or more storage-compartments, dependent upon the. size of the refrigerator and the use to. which it is to .be put. The ice compartment is disposed above the storage compartment, and all compartments are surrounded by al Water jacket having pipe lconnections for the circulation of Water' therethrough. In the specific formilljistrated AI provide an outside casinghaying Walls 10 of vany lsuitable construction and preferably includ? ing insulating material. Within the casing cells, each of'which is closed at the top, bottom, and at the backend opposite sides. The Walls.- of these cells are' formed of any suitable material but preferably lof meta-l or other good heat conductor. One of these cells 11 is disposed at the upper end of the refrigerator and extends 'across"approxi mately the full ,width thereof. being spaced from the sides, top and back of the casing to forni a. unter-circulating space 12. The remainder of the cells 13 lill the parts of the Specification of Letters Patent. I

casing below the cell 11, and are spaced from each other and from theadjacent Wallsof casing to form a vcontlnuation of the-water space 12. IThe walls of each of the cells are l connected to the Walls of the adjacent cells and tothe front edge of the casing by strips strips 14a', which closes the-space between -the compartment vor cell' 11 and the two adl l jacent cells or compartments 13, extends a stream of water 1n the Water jacket sur-v short distance above the edge of the cell4 11 to prevent Water on the bottom of the cell 11 from escaping at the lfront edge thereof. The'front edges of all of the cells lie in subrafented' March 1e, 1909;' 1901. seriaiNo. 398,908. I

stantially the same plane, andthe door 15 permits accessto any and all of the cellsffor the insertion of ice' or provisions. i If desired, a plurality of doors may be. provided, one for .eachof the cells.

For using the refrigerator When a supply of -cold'w'ater is available, I provide a Waterlinlet pipe 416 entering through the casing to the water jacket at. the lowerv ortion thereof,

and al Water outlet pipe 17. ceding through the'cas'ingto thewater jacket at the upper end thereof.

that -the 'creation of a' pressure within the water jacket is avoided should the Water be deliveredthrough `the pipe -16 with any desirable head. Thewater freely circulates The inlet ipe is preferably." somewhat'smallerthan t e outlet pipe, so r around five sides of each of the cells, the one side which is protected from the' eHect ofthe Water being vthe front, which isfnorn'iallyl closed by the door 15. All of the 'compartments or cells ITS/ may be used for the storage of provisions, and the upper cell 11 may also be used. for the saine purpose. When a supply of cold 'Water is not readily accessible, Iemploy the compartment. 11 as anice compart-' ment, and the drip therefrom is permitted to esca pe'through thedrip lpipe 1 wh" h leads through the space between the cells and from the interior of the compartment 11 t the exrterior of the refrigcrator;v The passage of the cold water-through the pipe 18Inay be relied upon to cool the Water standing in the Water jacket, or, if desired, open communication'A may be established throught-heice comparte ment and the`water jacket. :For this pur# pose I provide the bottom of the ice compartment with opeDingsIQ; Vadapted to be closed in any suitableimannerras, fornitbe kept cold.

25 and` the warmer stance, by plugs 20. The' drip water in thel lowerpo'rtion of the ice compartment below the inlet end of' the drip pipe, may communi cate through the openings 19 with the 5 warmer water in the jacket below and all of the water within the jacket below vthe level ofthe ice compartment will be maintained at substantially the temperature of the melting ice and all of the p The water within the-acket is not lonlycooled by the drip water entering through one or` more it also cooled by its engagement with the bottom wall of the ice compartment. lf the ice is comparatively impure and it is not desired that the sediment therein gain access to the water jacket, the'plugs 20 may. be left in place, and the compartments cooled andthel water within the jacket maintained in circu- 20 lation by the cooling ofthat portion of the water in the 'acket surrounding the ice compartment. Zin automatic circulation of this -water will be kept up by the difference lin temperature between the ice compartment below. Tit-h the plugs 20 removed, there will, of course, bey no water mithin the jacket above the level ofthe outletpipe'I 18. y

For directing ythe circulationof the water within the .jacketand for also aiding vin the support of the severahcompartm'ents, I prefe'rablyl insert oneormore spacing bars 21 extending in a vertical direction between the back wall of the casingand the backs ofthe storage 4compartments will of theopenings 19,V but provision compartments ment adapted for the storage of provisions,

an :upper compartment adapted to hold either provisions or ice, a water jacket inclosing bothof said compartments and eX- tending between the saine, a drip pipe leading from said second mentioned compart-- ment above the bottom thereof and .leading to the exterior of said refrigerator independently of the first mentioned compartment or said jacket, -means' for circulating a cooling fluid through said jacket tojcool both of said com artments, and means below the inlet end o said drip pipe for establishing i and said-upper `compartment whereby when said upper compartment is used for the storagel of ice the water 1n the lower portion of said compart'mentand below the drip pipe, may communicate with the water within the. portion of the jacket. inclosing the lowercompartment.

communica-tion between said water jacket In testimony l whereof lf' have signed my name to this specicationin the two subscribing witnesses;
