provide a 'rel'iigera such manner that the a primary refrigerant therein in the formation of ice in the refrigeiator, such ice then serving as a see ondary refrigerant.

A further object of the invention is to provide a refrigerator which is thoroughly sanitary and is adapted to be cleaned thoroughly and easily. I

Other objects and advantages will be apparent from the following description, considered in conjunction with the accompanying drawings, in which Figure l is aperspective view showing a refrigerator embodying the invention,

Figure :3 is a transverse vertical sect-ion through the refrigerator.

Figure 3 is a horizontal section through the refrigerator looking substantiall along the line 3-$1 of Figure 2.

Figure 4 is a perspective view of a refrigerant holding tray or receptacle which is comprised in the refrigerator, and

Figure :3 is a perspective view of an inner casing which is comprised} in the refrigerator.

A refrigerator embodying the invention comprises an outer casing designated generally 1 which includes a body that is sul stantially rectangular in horizontal sectional contour and is closed at its lower end and open at its upper end. The body of the outer casing may be supported on legs 2 and is provided at its upper end with a hinged lid 3. A relatively large preferably rectangular opening l in the front wall of the body of the outer casing normally is closed by a pairot swinging doors 5.

An inner box-liliecasing designated gen erally 6 also is substantially icctangular in horizontal sectional contour andis adapted to tit within the outer casing .t and to rest on i upon the bottom of the latter. The inner easing (3 preferably is close end by a bottom wall 7 and upper end. An opening 8 in of the inner istcr with the opening 4; .in of the outer casing when the disposed within the outer bottom and side walls of tacle designated of the inner casing 6 from walls of the opening 8 and the trout wall of the inner suitable known fastening casing.

It will be manifestthat acc to the interior of the recept the openings 48 when the secured to the or in any other ess may be had sole 9 through doors 5 are open.

\Vith the arrangement described, the space within the inner casing extends above the receptacle t). at the back and at the sides of the receptacle 9 and below the receptacle 9. A'vertical partition 13 extends within the inner easing t3 i'rom the upper end of the. latter approximately to the level of the top wall of the receptacle 9 and divides the space within the interior ot the inner casing above the level of (htreceptacle 9 partmcnts indicated respectively at 14. and

into two coin to. Each of these compartments is open at both its upper and lower ends.

The compartment H is adapted .t'or the reception of a removable tank a retrigerant tor cooling the 1S tor-holding interior of the of the compartment 7 inner casing 6 and oi? the ports associated with the latter. The tank 18 is in the form of o heir-like structure substantially rooted gnlor in horizontal sectional contour and open st its upper end being provided at its oppbsite sides with snspensionelements in. the form of straps 19 secured to the side 'wclls-ofthe tank 18 end having outturned upper end portions adopted to engage with notches 20 in the upper ends or" the" front and book Walls of the inner casing, whereby the tool: 18 will be supported Within the compertinent 14 with the upper end of the tank 18 edjecent to the level of the upper end 01.

Which they extend.

the inner casing 63. The end Wells of the tool: 1.8 may be provided with hhndles 21 adopted to be grasped to efi'ect the convenient removal. of the tank from the compare merit lei. The tank 18 is divided trans verse y by a. partition 2:2 to provide :1 plurality oi separate compartments Within the tank 18. All of these compartments are open at their upper ends but certain of the compartments, indicated at 23, are provided with drain openings 24: which extend through opposite sides of the tank at the lower ends of the compartments The remaining compartments Within the if, indicated at 25, are open only at their upper ends and thus are adapted to hold s. liquid It is to be observed that each of the compartments 25 is flanked by two of the compartments Each of the compartments 25 will he provided with a removable lid or cover, as indicated at 26.

The inner casing 6 and the outer casing 1 are provided With registering openings in corresponding end Walls thereof for estsc lishing communication between the lower part of the space Within the inner casing and the space exterior of the outer casing A drain ipe 27 may be removehly fitted in these registering openings and may have a faucet or other valve in the outer end thereof, as indicated at 28. Also, the Water l6 and the front Walls of the inner and outer casings may have registering openings at about the level of the lower end of the vessel 16 for the reception of :1 removable delivery pipe 29 which will have a valve 30 associated with. the outer end thereof. it to he un derstood that the drain pipe 27 and the do livery pipe 29 hove liquid tightconnection ith the no lie of the openings through l Vhen the valve 28 is open Water will drain. from the lower port of the space Within the inner casing 6 through the drain pipe and Will he (lischoiged at the outer end of the letter hut cannot pass between the drain pipe and the Wall of the opening; in one cud of the inner between the inner and outer casings. v.se, when the faucet 30 is openwater will flow from the vessel ill; through t liv v pipe 2S but water is not perniii meow? pass between the delivery pi 1e Well of the opening in the vessel 16 if interior of the inner casing; 6.

The object of making the drain p' w end the delivery pipe 29 removable these psits then do not prevent th of the inner casing iron'i the ootei c nor of the vessel 16 from the coinpert 15 since the drain pipe 2"!" and delivei;
