To all whomt may concern.'

Be it known that RAY A. Noiiwoonand FRANK 7. ViTiLsoN', citizens of the United States, residing at Columbus, in the Vcounty of Franklin and State of Ohio, and Corn? The present invention is directed tok im-I provements in refrigerators and particularly to those of the showcase or display type. The primary object ofthe invention is to provide a refrigerator of this character so constructed that the refrigerated air will freely circulate within the refrigerator and during the circulation thereof the interior of the refrigerator willY be maintained at an even temperature. v

A further object of the invention is to provide a refrigerator of this character with a refrigerant container having a novel arrangement of cooled air flues therein so arranged that a miximuni amount of refrigerating surface will be provided for the air as it. circulates through the lues, although the cubic capacity of the container is compara tively small.

With these and will appear as the descriptionproceeds, the invention consists vin the novel features of construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claims.

In the accompanying drawing: y

Figure 1 is a Vfront view of the device,

Figure 2 is a vertical sectional view therethrough,

Figure 3 is a sectional view on line 3 3 of Figure 2, and

Figure 4 is a sectional view on line 4-4 of Figure 2.

Referring to the drawings 1 designates the show casevrefrigerator which is preferably of such size as to be conveniently placed upon a store counter so as to occupy a minimum amount of space. The case has its bottom 2, sides 3, ends 4 and top 5 of double wall construction, filled respectively with suitable insulating material 6. One side is provided with door openings 7 which are normally closed by hingedly mounted doors other objects in View, as

8,"said doors 'having a plurality of spaced glass panes 9,.'tliis construction being such that articles can be observed in the case,

but atthe same-time assuring that entrance of air will be eliminated as long as the doors are closed.y Thesides arey also provided with similarly arrangedpanes 10,l and if desired the top may also be so constructed.

The top 5 isY provided with a centrally located Vopening 11, there beingfstrips 12 carried Aby the interior of the top and upon which rests the flanges v12l of the refriger! ant container 13 there being `a closure 14 for thetop opening 11 to permit the container to be conveniently filled with a refrigera'nt, such as ice and salt. The container depends into the case and divides said case into laterally disposed display compartments 14, said container having its bottom 15 spaced from the bottom of the case to provide a passage 16. Located in this passage is a pan 17 for receiving drip water from `the container, the water from said pan being discharged through a suitable drain outlet 18. v

Disposed transversely within the container 13 is a plurality of air conducting flues 19, preferably six in number, said llues beingdisposed in criss-cross` relation so that each set of three flues will have their upper or air entrance ends secured in openings 2O formed in the sides 21 of the container, the lower ends being secured in openings 22 formed neai the lower ends of said sides whereby the respective ends of said tubes Will be in communication with the compartments 14 to permit of circulation of chilled air throughout the entire cabinet to efliciently cool the contents thereof. It will be observed that the respective ends of the flues A19 are curved, as at 23, to eliminate any sharp corners which would tend to restrain the free circulation of the chilled air.

To the exterior surfaceof the sides 21 of the container are secured in any suitable manner elongated lioriz'ontally disposed manifolds 24 which communicate with the upper ends of the flues 19, and extended into said manifolds are the inner endsof the ducts 25, said ducts being supported in any suitable manner by the top 5 of the case 1, said ducts having their outer ends spaced from the ends 4 of the compartments 14 to nev permit air to freely enter thereintoforkpase sage through the `flues 19.` The .outer=. ends of these ducts are provided With a pluralityv of openings 26 inlooth` sides and bottoms thereof 'for the vpassage ofair. y Y

The arrangement of the-flues 419fin the manner shown not only enhances the circulation of the chilled air, but obviously provides a maximum chilling surface for the air. after it passesifron-i the ductsinto the adjacent upper' ends of the respective flues.A This airis thenl directed*downwardly through the' fluesfand -a continuous circulationofair is-produced, it being-.ofY course understood that the air also circulates :in the passageflG-f/ Thevcirculationof-airfis best indicatedy by the1arroivsshownin ure 2, and it xvillbe observed that this circulation isrsuchthat the cold airrwill descend-inthe -fiues l9-and will consequently be alternately--discharged from--fthe lower ends of said flue's, therebyI thoroughly chilling the interior of the refrigerator.

What is claimedlis:

LA refrigerator offitlie class .comprising a case, a refrigerant container andconnected With the upper ends of ysaid flues, With the lower ends of said fiues connected Withntheyother fcompartment.

2. A refrigerator of the class described comprising a caseTa refrigerant@container depending,l into, `the. ycase .and dividing .Yr-the case into independent display l hainbers,V a plurality. of yflues disposed: diagonally Twithf inthe container, ducts. and manifolds inV one of.. said. chambers connectedjvith fthe eri'ds,,0f said'tiues, the other ends ofi saidfluesbeing connected with the,othencoinpartinent..M
