This" invention relates to improvements in refrigerators especially adapted for dispensing ice creamer for-similar purposes.
Tlie'ebjeets of-the invention are:
First; to provide an improved construction and arrangement of refrigerating means "particularly adapted to an ice cream cabinet-1 i Sate lite provide an im reved support:
mg insane for the 'ikie container and ice cream cans within s'iich'cahin'et to insure a high ae'gr (if itineraries by facilitating circulation of the re riger'ated air. Third, to provide a refrigerator cabinet with an improved support andanangemem and cover mea s whereby a series of cans ar na-d available with very little mani'pulatien.
Further object's relating to details of (instruction and eperanpn will appear from the detailed description to follow; The inventioii is' "defined the "claims;
' 'A "structure which is a preferred embeaiment of m 1 antenna is illustrated in the aeeeinpanyie drawing, roaming pm er this application, in which: Fig: *l'i's a detail perspectii e'view of iny improved ice cream cabinet refrigerator, of three cans capac ty, two of the covers be-- ing snows iii poem-(imam with the lid removed.

The parts "will be referred to by numerals I ofieferehce which identify like parts in all theviews.
' 1 is the outer casing of an icec'reaiii refrigerator cabinet embodying the features of 'my invention. 2, ear-e the usual base supports for the same. 8, 8 "are the side walls 4. is the bottom: t is the inner metallic liningliaving an inclined bottom,
vertical back and slightly inclines front.-
The lining is' flanged at "51am retained in a place the top name structure. Insulation 6, preferably of; cork, provided between the lining and the outer casing. The outer casing is preferably made imperp'ervi'o'us to moisture by sheet ni'etal 3 or,
other means. The :top structurefis" coin pleted by longitudinal-rails '7, Ten which are'saperpos'ea the end "cross rails 8,8, the
one at the right having a slight inward prejeetiongand the on at the left being jogged outwardly somewhat to foriii ledges for engagement with the cover sections.
The coveris made up of three interchangeable sections 9, the left sides ofwhic h are provided with everhangingprejeeti ns 94 and th'e right si-d marina-med pr0 ec= none '95 that intrehgagewith eachother and with the end cross rails. The ends of the cover sections rest on the side rails. Lid
openings 91 are provided inthese covers opposite the ice cream cans within and are covered by lids 92, all of which are provided with insulation 93 and are suitably metal lined. I p
' As indicated in Fig. 5, asyrup container can be let into the cover back of the lid where it will be inconvenient position for dispensing syrup with the ice 'cream.'
lVithin the cabinet vertical spacers 10 are provided at the back wall, extending down across the inclined floor at -11 and up atthe front at 12, forming'an open space for the circulation of refrigerated air.
or refrigerant container 14;. The front of the ice can is inclined forwardly to overhang the ice cream can 15, which rests upon the bottom strips 11 in spaced relation from the bottom and in inclined position against the front wall. The ice cream can does not extend entirely to the top of the casing and of course maybe provided with a cover,
On thebottom strip 11 are supports 13 for the ice can loo which is usually removed during business hours. v p i The, refrigerant container 14 is provided with a handle 141 and with a strainer lid 142 which is hinged at 143. This contain r can of course be readily removed by the handle and the brine drainedout for repacking.
i In use the can 14 is ordinarily filled with crushed ice and then about one-fourth its weight of salt is placed on top. This is of course a very active freezing mixture and causes strong refrigeration of the surrounding air. The cold air drops down at the back of the can and at the front'drops down into contact with the back side of the can 15 and immediately circulates under the said can 15 and risesbetween the front slats 12 above the top of the can and circulates back through the open space above the can, and is thus very effective in completely refrigerating the can and its contents; Thecold air not only surrounds the can 15 but flows overitstop into the interior when the can cover is removed, and flows across the same and is continuously refrigerated and circulated so long as the refrigerant is active. The spacing of the refrigerating element is of the highest consequence and because of the use of salt upon the ice is 'veryactive and strong, producing a temperature'far below freezing. lVhere mechan cal refrigera [1011 1811886., the tank 16 may become a brine tank and be cooled by the usual mechanical refrigerant means 161, shown in Fig. 6.
Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is: 1 V r ;1. A cabinet refrigerator comprising an outer open top insulated casing, an interior lining with bottom inclined toward the front and with inclined front wall, spacer strips on said Walls vand bottom, and supports with level tops resting on said bottom spacers at the rear, a cylindrical can supported oirsaid bottom spacer strips and resting against the inclined front spacer strips, a refrigerant container with inclined front por tion and level bottom adapted to rest on said supports in spaced relation to the rear wall against the rear spacer strips and to the rear of and overhanging the rear portion of said can, and removable covers for the top of said casing, coacting as specified.
A cabinet refrigerator comprising an outer open top insulated casing, an interior lining with inclined front wall, spacer strips 'on the walls and on the bottom, a can suping against the inclined front spacer strips,-
a refrigerant container in spaced relation, to the rear wall against the rear spacer strips and to the rear of said can, andremovable covers for the top of said casing, coacting as specified. 7 7
In Witness whereof I have hereunto set my hand.
