DISPLAY REFRIGE'RATOR.

Applioatibn mm August 2a, 1921. Serial 'm. 495,649.

T all whom z't mag; concern l Be it known that I, ALBERT H. EHRLICH, a resident of St. Joseph, in the county of Buchanan and State of Missouri, a citizenot the United States, have inVented certain new and useful Improvements in Display Refrigerators, of which the following is a specification.

This invention relates to refrigerators,

W and more particularly to display refrigerators.

The object of the invention is to arran e the cooling medium in such relation to tl%e display compartment that the latter is l5 thoroughly cooled, and yet the goods 0n disglay are clearly visible.

further object of my invention is bo so construct the display compartment that there is a maximum circnlation of the air within the chamber, a.nd through und around the eooling medium.

In the accompanying'drawings:

Fig. 1 is a front elevation of the device;

[[ig. 2 is a side elevation thereof; Fig. 3 is a transverse vertical section on ig. 4 is a top plan view of the cooling tank and coils attached.

Fig. 5 is a modified view showing the tank as constructed for block iee only, the eoils being omitted;

Fig. 6 is a modified view showing the construction of the casing t0 accommodate a larger ice-box.

The refrigerator is provided with the usual insulating walls, and oorriprises a double chamber 1, and a lower non-cooled storage compartment 2. The display Cham- 40 ber is preferably provided with a curved bettom 3, and a front transparent Wall 4 consistin of a plurality of thieknesses of glass an a transparent top 5 similarly 0011- structed of a plurality of layers of glass.

The rear wall 6 of the display charnber is preferably solid, and has projecting inwardl therefrom a, horizontal counter portion Extending d-iagonally from the! counter portion 7, and adapted to engage the rear end. of the top 5 is a plurality of hinged doors 8, these dobrs likewise being made of a plurality of thicknesses of glass. This (1001 is preferably hinged at the bottom as at 9, the object being to have the upper end thereof swing outwardlyand inwardly in order t0 increase the circulation of air in the chamber as the door being closed would have a tendency t0 push the air from the upper portion downwardly through the bottom of the chamber.

Directly beneath the counter portion 7 is arranged an iee receptacle, 10. This re- .ceptacle preferably consists of a metal tank su pporied upon suitable legs 11, 11, and hav1ng diagonally arranged therein a plurality of tubes 12. These tubes converge toward their upper ends in order to increase the cireulation 0f air therethrough..

The front Wall of' the ice-tank 10 is referably provided with a plurality 0 V- shaped recesses 13, in order 130 increase the cooling area of the tank, the said*tubes 12 being arranged with the sa.id reeesseS. Leading from the bottom of the tank is a cooling coi1 14, which extends horizontally across the cooling chamber toward the front thereof, and projeeting vertically from the cooling coil is a. return pipe 15, which, as disclosed in Fig. 3, returns to the tank at a hi her level than the outlet to the coils.

n this form of cooling-tank, it is preferable to use cracked ice, which is sa.lted so as 130 force it t0 melt faster and absorb more heat, the brine therefrom is adapted to eirculate through the coi1 and return 130 the upper end of the cabinet. It is found that the brine goes way below freezing, and by combined use of the eoi1s and the (sank a mueh greater area is cooled, thereby rendering the cabinet more eflicieant.

Arranged direetly above the cooling coils 14 is a latticed metal shelf 16, the rear end thereof being supported on a bracket 17 secured to the tank 10. This o en she1f permits free circulation of air. ?n actual use, the air travels downwardly from beneath the eooling tank, and pa sses around the curved bottom, which acts to assist the 001d air gaining in speed. The air passes up along the vertical wall 4, and aeros the top 100 5, and downWardly against the inclined door 8, am]. thence over the t0p of the tank, and again asses down through, Where it is again cooled.

The numeral 18 'indicates movable eovers 105 arranged directly above the cooling tank 10, whereby the latter may "be re-eharged with eooling medium.

The lower non-cooled sborage tank 2 preierablyis provided with a rear door 19, and, 110

'if deSirable, rolls of paper 20 may bo couveniently arrangedtherein for use.

As shown in the modified view in Fig. 5, the ice tank 10 is provided with an open bottom 21, and a latticed front wall 22, this tank being particularly adapted for block ice, the open bottom and walls serving to permit the air to circulato freely around the ice contained in the tank.

I claim: Y

l. A refrigerator comprising a display chamber provided with .a. curv ed bottom, and transparent freut walls and to a rear horizontal cotmterportion provided w'1th lids and an inclined transparent door arranged bet ween the counterportion and the rear of the top, a perforated shelf spaced from the bottom of the display chamber, a cooling tank provided with a plurality of inclined tubes, a cooling c0il extending 'laterally fro1n the tank toward the front of the chamber and beneath the display shelf being connected to the lower part of the tank and having an outlet leading to the upper part of the tank.

2. A refrigerator comprising a display chamber provided with a curved bottom, and transparent front walls and top, a rear horizontal counterportion provided with lids am]. an inclined transparent door arranged between the counterportion and the rear of the top, a perforated shelf spaced from the bottom of the display chamber, a cooling tank provided with a plurality of .inclined tubes', the'e front wall of said tank being recessed to in'crease the cooling surface of the tank, a cooling coil extendin laterally from the tank toward the front 0 the chamber and beneath the display shelf being conneoted to the lower part of the tank having an outl'et leading to the upper part of the tank.

In testimony whereof I hereunto affix my signature.

ALBERT H. EHRLICH.
