BRICK ICE-CRAM PACKING AND COOLING: CABNET.

Application led July 25, 1927. Serial No. 208,222;

This invention relates to ice cream cabinets, and is particularly concerned with a structure of cabinet for the packing and cooling or refrigerating of brick icecream. It is the object and purpose of the present invention to provide a novelgforin of cabinet and particularly a novel form of holder or container for brick ice cream which may be placedin the cabinet, one or more of the same, whereby the bricks of ice cream may be maintained at a desired low temperature', the refrigerant holding receptacles at all times being free of the brick ice cream holding receptacles, not freezing together, and in whereby a proper circulation of air within the cabinet is provided, thereby making the temperature Vsubstantially uniform within said cabinet. j An understanding of thek invention may 2o be had fromthe following description taken in connection with the` accompanying drawf ing, in which, f .v

F ig. l is a. vertical transverse section through the cabinet of my invention.

Fig. 2 is a plan view thereof, the upper closures of the lcabinet being removed, yand Fig. 3 is an enlarged perspectiveview'of one of the brick ice cream holding containers. Like reference characters refer to like parts in the different figures of thedrayw ings.

'lhe cabinet 1 isfof ywell known construction, having agbottom, vertical sides and ends, and an open top in which there is a f large opening to receive the ice cream holding cans and the refrigerant holding'receptacles. Said recess is properly linedvand is insulated from the outside by means of cork 4G board or other suitable insulation. The cabinet is of the type and construction shown in the patent to Phillip Fritz, issued January 5, 1926, No. 1,568,216, and its specific structure need not be further set forth. ln cabinets of this type there is a central well 2 extending lengthwise of the cabinet, above which the opening in the cabinet is widened, with the provisions of shelves 3, one at each side and a distance above the 4 lill lower end of the well 2, on which receptacles a containing the refrigerant, ice and salt,

c are located. A. lurality of such receptaclesy are at eaciv side of the well with their zontal plane.'

irmer sides in vertical planes, and their outer sides tapering upwardly and routwardly from the vertical. Such receptacles, by reason of the limited height thereof and because in the length of the cabinet a number of the same are used, `are light enough, even when filled with crushed ice andsalt, and aref of such height that they are readily and easily handled for placing in or taking out of the cabinet. c

lt is betweenthe refrigerant holding relceptacles l that the ice cream containers` arey placed. lith my invention the ice cream containers each consist of a sheet metalcan, substantially square in outline.havingcan upper end and of such size thatthe lower end of the can may be received in the lwell y2 to lie betweenthe refrigerant holding ref.

ceptacles il' at opposite v'sides of the cabinet.`

With my invention each side of thecan 5 is formed with a plurality of outwardly pressed embossings or projections 6. `In practice there are a pair of said projections near both the upper and lower endsv of each 'side` of the can. All of the projections 6 at the lower end of the can lie inthe sameV horizontal plane. Likewise all those at the upper end ofthe can liey When these cans are placed in the cabinet the lower projections 6 are in the well 2 and may bear against the vertical sides of the lining of the well, thus locating the can in the weiland holding, spaced apart the sides of the can and thesides of the well. 'lhe cans -which are at vthe ends of'thewell are 'likewise spaced lfrom 'the yend of they linings of the cabinet by the projections 6. [The adjacent lsides of two cans 5 are spaced apart by reasony of the vfact that the projections 6 made on the adjacent sides of the two cans come directly against each other as full shown in Fig. 2. lt is also evident that the inner sides of the ice cream holding receptacles a are held spaced from the sides of the cans 5 by the upper projections 6. This insures that entirely around each one of the brick holding cans 5 there is a continuous air space, permitting free downward movement of cold air from the inner sides of the refrigerant holding receptacles between the cans and upwardly betweeri said cans and between the end and the ends in the same horiof the cabinet. The sides of the cans 5 are provided with a large number of perforations for further aiding the circulation and bringing the cold air in contact with the ice cream held in said cans.

The space between the ice cream holding cans `5 and the refrigerant holding receptacles a also precludes any possibility of intimate contact between rthe sides. of the said cans and receptacles and their freezing together as would otherwise occur; `-Such freezing together is very undesirable, restricts irculation, defeats uniformity of temperature and makes it hard to` remove the refrigerant holding receptacles when the same are to be drained and replenished with refrigerant. l.

lt is, of course, evident that it is not necessary to use the brick ice cream holding cans 5'V the entire length of the well, 'but that it ,is very easy to replace one or more ofjthe cans 5 with regular cylindrical bulk holding` icecream cans, such bulk holding cans being interchangeable with. the square cans shown y inthe present invention. It is further evident that the cans, shown are not restricted in use to holding brick ice cream alone but that many other articles which aretoifbe maintained in a cool'condition, such `as the socalled"Fr ost Bites, Eskimo Pie and the'lke and many and various articles `of,

food may 'be held in such cans andmaintained in proper refrigerated condition.

The invention is defined in the appended claims and should be considered comprehensive of all `forms yof structures coming within their scope. f

:I claim:

l. In ,an ice cream cabinet having an opening into which refrigerant holding receptacles are adapted to be placed, one at 'each` side of the opening in spaced,apartI relation, a can of rectangular outlineadapted,to,be located between. the refrigerant holding. ren ceptacles and formed at its sides-,with outwardlypi'essed projections to engage against the adjacent sides of .the refrigerant holding receptacles to thereby properly locate said receptacles and can with respectto` each other and space the samefromfeach. other, said projections beingspaced apartA to perother, `and projections pressed outwardly in oppositesides of saidcan and spaced apart to permit vertical air circulation past. and

- between them, substantially as and for the purposes described.

l3. A can of sheetfinetal open at its upper end adapted `to be placed in an ice cream cabinet, having vertical sides located at right angles to eachother, saidvcan being of square outline, and projections pressed outwardly in each side of said can and spaced apart to permitvertical air circulation past and ,between them, the outer points ofall the projections ina side of the can lyinr in substantially the same vertical plane;

4. Incoinbination with `an ice cream cabinet having an opening in its upper side, the central portion of which is deeper than at theside'portions thereof, thereby forni ing a well, of a can of rectangular outline made of sheet metal located inl said well the opposite sides of said'can adjacent the sides of thewell being formed with outwardly eX- tending projections spaced apart to permit vertical ,fairV circulation` past landfbetween them, andYrefrigeiimt holding receptacles locatedat .each sidefof thewell with their inner sides contacting with theouter points ofsaid projections onthe can, said projections lonthe can located thevwell contact-f ingwith opposite `sides of the well.

`ifncanforuse with ice cream cabinets,

inadeof sheetlinetal and square in-cross section, havingvertical .-sides, a plurality of spaced apart projections extending outwardly from`V each side of the` can adjacent theI 4upper fendl thereof, said projections beingpressed from the metal of the can and all located in the same horizontal-plane, and other :spaceduapart projections pressed `outwardly fromjeach side of the can near the lower A end 4thereof, all `of said projections 'adjacent` the lower end of the can lying in the same` horizontal plane.

`In testimony whereof I aiiiX4 my signature.'

EDWARD MLFRITZ.
