REFRIGERATING APIPARATUS.

Application filed May 18, 1912. Serial No. 698,329.

T 0 all whom it may concern 'Be it known that we, Jncos J noon R. vHessiansin-21X, citizens or BLE'NZ and the United States, residing at Decatur, in the j county of Macon and State of ll. mois, have invented certain new and useful Improvements in Refrigerating Apparatus, of which the following a specification. reference being had to the accompanying drawings.

This invention relates to improvements in refrigerating apparatus and has tor its object to provide means whereby a constantlj',

circulating current of cold air may be. sup-- plied to the provision chamber froma minimum quantit of ce or other refrigerant, thus inatern ly reduclng the expense incident to the operation of apparatus of this character.

Another ob ect of the invention 1s to pro.- videan ice box provided with 311311 receiving chamber, means arranged in the box beneath said iceto receive the air, and a fan having a pipe connecting the same with the air chamber, said tan directing the tar into and throughsaid recelvlng means. in

' the icebox to a supply pipe connecting the air chamber with the provision chamber of the refrigerator.

Still another object of the invention re sides in the provision of a brine containing tank and a pipe connecting the same to the air ch mber of the ice box, and a pipe connected at one of its ends tot-he bottom of the provision chamber and at its other endto said first named pipe to return the air from the provision. chamber to the cold air chamber of the ice box.

. A. still further object of the invention is to provide an apparatus for the above purpose which is comparatively simple in its. co

struction, may be manufactured and installed. at small cost and ishighly efficient and reliable in practical'use. I v.

With the above and other objects in view as Wlll become apparentas the description proceeds, the invention consists in certain constructions, combinations and arrange ments of the parts that wev shall hereinafter fully describe and claim.

"For a full understanding f. the invention, referencev is to be had to the following description and accompanying drawings, in

whichl is an elevation, the Walls of the refrigerator being shown. in section; Fig; 2

a top plan view; It ig. 3 is a'sect ion'taken on theline 33 of Fig. 2 and Fig.4 is a. tntunal section taken on the line '44.-

Corresponding and like parts are referred to in the following description and laccompanying drawlngs by like reference characters.

in which a horizontal flooror, partitionfi is arranged to prov1de upper and lower com- Referring in detail to the drawings, 5110signates the body walls of the refrigerator;

partments. The lower compartment of the refrigerator is furnished with the usual hooks, hangers and other accessories upon which meats and other, provlslons are arranged. In the upper chamber 5 an ice box a 7 is arranged. This icebox is'. preferably of rectangular form and on three sides is provided with inner and outer walls 8 and 9 respectively, to provide an air receivingchamber 10 between them, These walls may be constructed inany desired manner, and.

provided with a heat insulating medium.

The other wall 11 closes the .airreceiving chamberlO at one of its ends. r

/Vithinthe ice box-7; and uponthe bottom thereof the air receiving member 124s ar- I ranged. This member consists'of-spaced ransverse pipes 13 and a plurality of longitudinal pipes 14 which connect the trans-- verse pipes. Ulpon these pipesthe-supply of ice within the chest is arranged.= One of the pipes 13 is provided with a 'centralre duced laterally extending nipple .15, to

which a pipe 16 extending from the-fan case 17 is connectedfih e nipple'lo-e'xtera ling,1

through the endwalls 11- of the'ice box' adjacent'to itsll'ower end-.1 J'A fan'18 is. arranged in-the casing 17 and the fan 'shaft is provided on one end with a band'wheel to shaft of a motor'is connected. A pipe 19 is also connected tothe fan case at one of it's' ends, the other end. of said pipe being extended through the end. r all 111. of the ice box into theair chamber thereof.

Through the other end of the icebox' a pipe partition wall G'andbeing provided upon which a driving belt "extending from thee ing centrally from the other .of the transverse pipes 13 of the air receiving member 12. "By means ot'wthis arrangement'of -parts ii t' itwill be readily understood that the air is ,drawn.-into' the. fan case from the chamthe chamber, of the ice box.

ber 10 through the pipe 19 and driven into .the' end pipe 13 of the {member 12 and through the longitudinal pipe-e 14 into the other end pipe 13 vfrom which it is exhaust ed through thepipe '20 into the provision chamber of the refrigerator.

The-chamber 10 of the ice box is constantly supplied with air from a brine tank -'23- -:-wh ich is arranged at any convenient po nt nflthe provlsionchamber and is c0nnected to said chamber by means of the pipe 24, the walls of. the tank 23-being provided with suitable. air inlet openings; shown at"v 23. A d-raln pipe .25 extending from thebottom of the ice box 7 carries .the water from the melting ice, to the upper end of the brine tank 23. Thiswater percolating through the brine in the tank generates a vapor'which rises through the pipe 24 and enters the chamber 10 of theice chestr A pipe 26 is arranged in the tank 23 and extends to the surface of the brine therein to receive the overflow, the lower end of the plpe extending exterio'rly of the tank to discharge the water and brine.- To the pipe neath the ice in the manner above stated. It will thus be apparent that a constantly circulating current of cold air is maintained through the provision chamber of the] refrigerator.

- The expense incidentto the consumption of ice is materially reduced by means of our improved apparatus and even when the ice. supply has become entirely exhausted, the

cold air rising from the brine tank and be ing driven by the fan through the ice box will still maintain the provision chamber at a low temperature.

From the foregoing 1t is'believed that the construction and manner of operatlon of our improved refrigerating apparatus will be clearly understood, The device is extremely eificient, and reliable inlactual use and owing to the sim plicity ofits construction, the same may. be

readily installed in the ordinary refrigerator at comparatively small cost.

While-gwefhave above set forth the preferred construction and arrangement of the various parts employed, it will be obviousthat the invention is susceptible of considerable modification without departing from the, essential features or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is:

1 I-;'-- In a refrigerating apparatus, an ice- "chest having an air chamber, an an re .ceiving g'r1d'- arranged 1n sald chest and provided with an inlet for the cold air at one of its ends, a discharge pipe connected to the other end of the gridto receive, the

airtherefrom'and discharge the same into the provision chamber of the refrigerator,

chamber, an air conducting pipe connected to the brine tank and to the air chamber tr supply air to the latter, and an air return pipe connectedto saidlast referred-to pipe and extending into the provision chamber to a point adjacent the bottom thereof.

a brine tank arranged in the provision 2. In a refrigeratingapparatus, an ice chest provided with an air chamber, an air receiving grid arranged in said ice chest" upon which the ice 1s supportedfa fan connected 'to said grid, a pipe connecting the fan case to the air chamber of the ice-chest, a brine tank, a drain pipe connected to said tank and .to the ice'chest, an air conducting pipe connected to the tank and to the an.

chamber of the chest, a discharge pipe con- 'nectedto the grid to discharge the cold-air therefrom into the, provision chamber of the refrigerator, and a pipe connected to the provision chamber and to" the pipe connection between thebrine tank and the chamber of the "ice chest to return the com-paratively warm airfronrthe provision, chamber to the chest chamber.

In testimony whereof we hereunto -aflix oursignatures'in the presence oftwo wit-' nesses. v
