' To all whom' it may concern:

Be it known that I, CLIFORD W. REY- NoLDs, `a citizen of the United States, residing at- Omaha, in the county of Douglas and State 'of Nebraska, have invented certain new and useful vImprovements in Refri erators, of which the following is a specication.

My invention relates-to household-refriger- Io at'ors; and the objects thereof are to rcvide a refrigerator of this class of which alii/parts are readily accessible for cleaning, thus making a sanitary construction; to provide efflcient insulation without making adevice so i5 vheavy as to b e difcult to handle; to pro?Y vide large ice-storage ca acity proportionate t'o the slz'e and weight o thecasing; to pro- Yvide efficient andra id circulation of dry cold air Within the re 'gerating-chamber; t'o

provide a moist chamber for the storage of vegetables and the like, means for collecting the water formed. by melting of the ice and ,for intermittently sprinkling said water within the moist chamber, and to 'rolvide withinthe refrigeratingechamber she ves adjustable as to height and rotatable, so that all J parts thereof' may be brought adjacent the door of the chamber for convenience in lac-, ing articles thereon or-removin'g same t erefrom. These objects are attained by the construction illustrated in the accompanying drawings, in whic'h- Figure 1 is a sectional side elevation of the device. Fig. 2 is -a sectional plan of the same, the section bein taken on the plane 'indicated by line x of ig. 1. Fi .-3 is a detail section through the water-co lectin isiphon-cup. Fig. 4-is a detail plan view o the. sprinkler-nozzle, and'Fi .4 5 is a section of the same on the line y of `g. 4.

In the construction shownI provide a cylindricalsheet-metal 'casing 1, 'the same havv ing double wallsinclosing an 'air-space2. At theto of the cylinder is the removable dou- 45 ble-Wa led Alid 3, having the handles 4 for conyenience m removing the same. 'A suitable dlstance above the bottom plate 5 of the casing `isa partitionlate 6, dividing the linclosed space intojt e' upper or refngerating;

chamber 7 and the lower or moist chamberS.- 1 Access to the said chambers isy rovided by the doors 9 and .10, vopening tlxiereinto, res ectively, at the frontof thecasin 'Said oors are provided with hinges '1,1' an latches` 12',- of suitable form, as shown'in'Fig'. 2. -I

The ice-pan 13 has the straps 14 secured on.

.the flanges around The fis placed' the u?,

the sides thereof, as shown, thel same terminating at their upperends i'n hooks which engage the shoulder beneath the lid 3 and re-4 movably vsuspend the ice-pan within the refrigerating-chamber. The said ice-pan is tapered from top to. bottom, so that a'space is between the same and the walls of the casing, and near the top of the pan are a number of openings 15, through which the air-currents rising adjacent thevcasing-walls may pass in over th ice in the pan. The

bottom of the pan is slightlyinclined towardv one'side and has the large upwardly-flanged openings 1'6 therein,'o`ve r which is the remova le imperforate plate 17, having ,thereon the` downwardly-extending perforate fianges 18,

ton -of cold air isvpermitted to pass through' the perforated flanges 18 below the platefl? and, thence downwardly through said open'- ings 16.

At the center of the partitionplate 6 the vertical shaft 19 is su ported by a suitable vstep-block 20, said sha t being held at its upper end by a similar block secured to the bot.- tom of the ice-pan. At suitable intervals on the said shaft are laced the collars 21, which are adjustablyheid in position by set-screws 22. On said adjustable collars are revolubly supported shelves each comprising a perforated circular plate of sheet metal 23, ywhich is-downwardly-flanged at the outer edges and supported by the T-section arms 24', uniting in a hub'V at the shaft, as shown. The perforation of the shelves 1s Vfor the purpose ofV ermitt' free downward movement of col air from t e openings 16 in the bottom of the icepan thro/ugh the shelves tothe bottom ofthe l chamber. l The u ward return-current of warmer air passes etween the outer edges of the -shelves and the inside of the casing up to the openings 15 in the ice-pam as before de-l scribed. o from the ice inthe pan 13 `upon realta t e'inclined bottom ofthe an owsl to the -ain-"tube'25 at the side o fthe* pan` and `is conductedthe'eby to the Siphon-cu '26, whichis removably supported at the si el o f-thecasing in brackets 27'. Inthe cu 1265.

sihon-tubeS, the top -o the end-therein eing disposed below the top eg of the tube pass' ing through the bottom of the cup and extending`l downward adjacent the casing-Wall throug the partition-plate 6 into the moist chamber 8, as shown. At the bottom of the tube 4Within the moist chamber is placed the sprinkler-nozzle, comprising the ta ered tubular shank 29, fitting within the sip on-tube 28, as shown in Fig. 5, and the fan-shaped hollow sector 30, having the small o enings in the outer rim thereof. (Shown in igs. 4 and 5.) As the drip from the ice fills the cup 26 and the water-level therein reaches the top of the U-bend in the Siphon-tube' a flow is established through the tube, which quickly empties'the cup, the water descending through the tube With -suflicient pressure to spray through the sprinkler-nozzle into the moist chamber. Thus Ythe Water collected in the cup 26y will be `intermittentlyI discharged through; the Siphon-tube, the discharge taking place at regularintervals, the time between which depending on the size of the cup and the rate of meltin of the ice.

In the bottom of t e moist chamber is a removable rack 31, on Which may be placed vegetables or the like in position to receive the s ray fromv the nozzle. The bottom 5 of y the c ,amberis inclined toward the center, at

which is a suitable drain-opening 32 for the escape of the Water, the casing being placed .on1egs33to permit a suitable drip-pan to be placed below said opening.

It will be apparent from the drawin s thatby removing the lid 3 from the casing t e icepan may bereadily lifted out of the same and the shelves,nvertical shaft, and Siphon-cups similarly removed, the sprinkler-nozzle at the bottom ofthe Siphon-tube -being removed through thedoor 10 of the moist chamber. The rack 31 `may -be similarly removed through ,the door of the moist chamber, so that every part'of the refrigerator is readily accessible for cleaning. Should it not be desired to use the water discharged from the siphon-tube'for sprinkling of articles in the jsiphon-tube'..

p (The refrigerator being made throu hout of metal may be finished in any suitab e manner, but is ypreferably enameled to form a K smooth non-corrosive surface.

Now, having described my invention, what I l claim is-,

1. In a refrigerator, a casing divided into an upper anda lower chamber, an ice-pan disposed near the top of the casingwithin the upper chamber, a cup/adjacent the ice-pan and arranged to receive the drip therefrom, a Siphon-tube leading from said cup to the lower chamber, means on said tube within the lower chamber for spraying the discharge therefrom into said chamber, and means per-l mitting the escape from said chamber of the Water sprayed therein.

2. In a refrigerator, a casing divided into an upper and a lower chamber, an ice-pan suspended within the u per chamber near the t'op thereof, revolub e perforate shelves within said chamber below the ice-pan, -a cup held near the ice-pan and arranged to receive the drip therefrom, a vSiphon-tube leadin from said 'cup to the lower chamber, sai tube being adapted to intermittently dischar e the contents of the cup, means carried on t e lowerend of the Siphon-tube for spraying the discharge therefrom into the said lower chamber for the purpose set forth, and means .fdr draining from said lower chamber the water discharged thereinto by the In testimony whereof I have hereunto subscribed my name infthe presence of two witnesses.
