The present invention has to do with a. storage and dispensing cabinet for chocolate coated ice cream bars, generally' known as Eskimo pies and other frozen confections of a regular shape and size.

Among the objects of the invention, the following. are included l A compact storage cabinet-'particularly adapted to use solidified carbon dioxide or, as it is known in the trade, dry ice.

An Aunique unit holder adapted to be enclosed in an insulated container providing jlfneans for dispensing chilled objects there- Anunique combination of insulated cabinet andv removable object holding carrier, the object holding carrier providing means for containing the refrigerating element.

These, and such other objects 'as may hereinafter appear are obtained by the novel construction, combination, and arrangement of the several elements which constitute the invention, one embodiment of which is disclosed in the accompanying drawing, .in

which Figure 1 is a perspective view of m proved cabinet, part of the view eing broken away to indicate the features thereof;

Figure 2 is a vertical section through the cabinet, the door thereof being partially ajar;

Figure 3 is a perspective view of the interior supporting portion of the cabinet;-

and

Figure Il is a perspective view of the box member for containing the cooling means. Like reference characters are used to vd esignate similar parts in the drawing and in the description which follows.

n the several figures the numeral-10 is used to designate'a cabinet, which may be of one or several thicknesses of material. lt is necessarily insulated and adapted to retain the chilled air used `in refrigeration therein, and to exclude the warmer atmospheric air. Any suitable material may be' used, and as structures of this sort are common, the figures merely indicate a unit f wall. s Y

lin the lower `front section of the .cabinet 1() is an aperture 11, constricted as the central portion of the cabinet 10, is approached. Aperture 11 is closed by a door 12,- suitably hinged or otherwise fastened. j

Any suitable locking means maybe employed. Door 12 fits closelyv against the walls surroundin aperture l1 in order to prevent excessive eakage of chilled air from the internal compartment of cabinet 10; such compartment being designated by the numeral 13.

A cover 14 is adapted to enclose a central section y13` of cabinet 10 and this ma be hlnged or otherwise held`\in position'. removable cover is necessary according to the structure here disclosed.

Within the cabinet 10 is a carrier member 15 which is adapted to vbe seated in space 13. Preferably the container 15 is of `such size that it completely lills such space leaving comparatively little air space between the container 15 and the walls ofcabinet 10. d Container 15 comprises sides 16 and back 17, generally made of a single sheet of material bent in two places at right angles. Three separate pieces may be employed and these fastened in any suitable manner. Reinforced edges may be supplied or other means used to strengthen the structure.

A bottom 18 vof sheet material extends Afrom one side 16 to the opposite side 16 and for purposes of strengthv is generally soldered or otherwise attached to the bottom edge of back 17. The material of container 15 is preferably copper and may be corrugated or` ribbed or otherwise formed in order to provide a large radiating surface.

'Extending upwardly from the bottom 18 are a plurality of dividers 19 each prefer'- ably of sheet inaterial and extending from the fronts of container 15 to the back 17 thereof. Dividers 19 extend upwardly a part of the way toward the top of the device and terminate in shelf 20 of foraminous material'. yIn this manner the container 15 is divided into a plurality of storage sections extending th major portion of its' height and into each of these storage sections is deposited the frozen confection or other article which is desired to refrigerate.

The upper section of 15 comprises a section for the deposition of dry ice, which substance is ordinarily supplied in cake form enclosed in a paper box. Such box is deposited upon the shelf 20 and the refrigeraftion action is obtained by the evaporation of the dry ice and by the distribution of the carbon dioxide` released during such evaporation throughout the container.

f To use the device it is customary to load the container 15 with the articles to be chilled, after which the container 15 is invSerted into the ycabinet 10. The dry ice contained in the paper box, as above described, is deposited upon the shelf 20, and the cover 14 placed upon cabinet 10. c

Articles under refrigeration are-removed by opening the door 12 and such removal continues until a new stock of Eskimo pies or other articles are .placed in the container 15, the loading thereof generally being accomplished after its complete removal from the cabinet 10.

Additional refrigerating material is in- .15 serted merely by the removal of cover 14.

Experiment has disclosed that in this type of device, copper provides for the more elficient operation thereof. Because of the high conductivity of copper, it is readily chilled by the action of the dry ice, and -a lower temperature is maintained in container when copper is used for the `production of member 15 than when other metalsare employed. Corrugation of the ,o material increases the radiating surface and, of course, increases the refrigerating value of the device. x

if clairnzc f '1. A refrigerating device comprising an insulated cabinet having a discharge door adjacent its-l bottom and a cover, a removable containerfenclosed upon three sides and divided vertically by a fora-minous shelf, and a plurality of "vertical storage sectionsbeneathsaid shelf;

2. A vrefrigerating store" Eskimo pies lated cabinet having a removable cover and cabinet ad'apted to ra discharge door adjacent its bottom and at.

lone side thereof, and a container member adapted to be inserted into 'sa-id' insulated cabinet comprising a sheet of corrugated copper folded lto form three sides thereof, a foraminous shelf disposed therein, a bottom of' material similar to the sides thereof, and a plurality `gof yfiat sheet'smembers intermediate said shelf and said bottom to provide vertical storage sections ofthe width and said ice cream 'confections comprising an insular to the sides thereof, and a plurality of flat sheet members beneath said shelf and extending to said bottom to stora e sections.

' 4. refrigeratingdevice adapted to store ice cream confections comprising an insulated cabinet, a plurality of upright mem* 4bers in said cabinet dividing said cabinet into a plurality of narrow vertical storage sections for the ice cream confections, means positioned above said upright members for -supporting solidified carbon dioxide, said means permitting the vapor from said solidifled carbon dioxide to be admitted into the vertical storage sections, and means furnishing access to the lower portion of said vertical storage sections to permit removal of nishing access to the confections comprises` afdoor formed in the cabinet, said door being substantially ofthe same thickness as the cabinet, hinged 'at Ythe topl and tapering toward the inside wall thereof, thecorreprovide .vertical sponding aperture in said cabinet being tai pered to permit a snug .fit of said door against said member,
