15 Claims. (UL 312-185)
This invention relates to cold storage cabinets
' and more particularly to those types of cabinets
which are used for ice cream service in retail
space quickly accessible from the cabinet opening
directly above it.
stores.
5 I In such cabinets ice cream and the like is kept
in bulk, under refrigeration, and the cream‘ is
dipped from cans or other receptacles as cus
tomers call for it. Formerly it was customary to
stock the cabinets with ice cream in ?ve-gallon
10 cans, but the best present practice substitutes two
and-one-half-gallon cans to provide a wider range
of available ?avors and kinds of ice cream and
to permit emptying and replenishment of the cans
‘at shorter intervals so that the stock on hand is
always comparatively new and fresh.
The two-and-one-half-gallon cans are com-‘
monly of the same diameter and of approximately
one-half the height of the ?ve-gallon cans.
w?l to superpose the blank space over any se
lected lower can or space to render such can or
Used
in the same cabinets, the shorter cans are stacked
two high, or the space beneath a can may be used
to store packages of brick ice cream, boxes of
ice cream bars, or allied loose goods which gen
erally move more slowly, and inasmuch as the
cabinets invariably have closed sides and bottoms
and are provided with top openings only, it has
been necessary to provide means ‘for rendering
the bottom cans or the loose goods in the lower
zone of the cabinet conveniently accessible to an
attendant reaching through the top opening.
This prior art construction has proved to be
unsatisfactory for several reasons.
In the ?rst place it fails to provide sumciently
stable support for the cans of the upper tier- lit
has‘ been found in practice that the horizontally
movable. carriages tend readily to move under the
efforts of the cabinet attendant to dip ice‘ cream
from the cans supported by them. When it is
remembered that the ice cream is kept hard
frozen at around 0° Fahrenheit it will be appre
ciated that digging thrusts of considerable force
arerequired to free portions from the mass. To
dip the cream evenly from the whole inner pe
riphery of the can, these forcible diggin‘g thrusts
must be made against all sides of the can interior,
and when such a thrust is directed against an
_unsupported side of the can (in the direction of
5
10

20
the unoccupied space in ‘the tier) , the ‘can
promptly slides'unless it is held by the free hand
of the attendant. For sanitary reasons it is of
course undesirable tohave the can lips touched 25
by the 'attendant’s ‘hands.
‘
A second" reason why this horizontally sliding
arrangement is unsatisfactory is the fact that the
cans on ‘the freely slidable carriages are seldom
found aligned, when the attendant removes a cab- 30
Unless some such special means be provided it
would be necessary, in the case of a well ?lled ' inet cover, with the openings directly beneath
cabinet, bodily to remove from the cabinet an which‘ they are supposed to be positioned. This
upper can to reach a lower one or to gain access results from the tendency of the cans to “bounce
to loose goods in the bottom, and this is maul
back” after being slid into impact with the cab
festly inconvenient, unsanitary,‘ time-consuming,
inet end or with another can. It thus frequently 35
happens that the cans of the upper tier are quite
and wasteful of refrigeration.
An object of the invention is to provide means
for rendering the lower cans or goods readily
accessible through the top opening. '
41)
It has been proposed to mount the upper cans
on horizontally sliding carriages provided in a
number equal to one less than the length of the
cabinet would accommodate. Thus, a cabinet
built to hold four five-gallon cans in horizontal
ex cm alignment would be stocked with a lower tier of
four two-and-oneLhalf-gallon cans or their equiv
alent in loose goods and with an upper tier of
evenly spaced apart, none of them being directlyv
under a cabinet opening, so that special realign
ing by movement of the canals required prac
tically every time access to any can is desired.
40
an ‘additional difficulty encountered in the op
eration" of this prior art construction results from
the unexpected and capricious binding of the sup
ple expedient of sliding the covering carriage and
port rollers at times consequent upon the con
densation and freezing of moisture in the bear- 45
ings' Thus, a can will at times requiretconsid
eraple force to move it, or it may be very easily
movable. Because the operator cannot guess
what degree of force will be required he invar
iably gives the can a sharp blow of the hand and 50
if the rollers happen not to be frozen the can is
set in violent motion and may oscillate through
several periods in its allowable range of move
its can from over them. The cans and carriages
of the upper tier can obviously be rearranged at
back" from the adjacent can or cabinet end wall F
three two-and-one-half-gallon cans. Through
the unoccupied space of the upper tier a single
lower can or its equivalent is thus rendered ac
cessible, and other lower' cans or their equivalent
space can be uncovered and reached by the sim
ment before ?nally coming to rest, "bouncing

and ultimately distorting the cans and the cab

tion asmany as seven two-and-one-half-gallon
cans may be used in lieu of the four ?ve-gallon
.-
'
Furthermore, the sliding support construction
requires the trackways for the support rollers to
'10 be 'very securely ?xed to the cabinet walls. It
is practically impossible to perform the neces
sary bolting or riveting operations in a com
pleted cabinet. Hence the sliding support con
struction cannot be installed in already built
15
of the ?ve-gallon cans or the equivalent space.
As I have explained, in the preferred present
cabinets.
'
Objects of the present invention are to over
come and eliminate all the foregoing disadvan
tages of the sliding support constructions; i. e.,
\to provide a construction in which. the movable
cans are stably supported against undesired
movement regardless of the direction of digging
thrusts at the hard frozen contents; in which
the movable cans are always necessarily posi
tioned at precisely one end or. another of their
.25 allowable range of movement, so that the upper
cans and the blank space are always aligned
with the top openings and with the lower cans
or spaces; in which the binding effect of frozen
condensation in the moving parts is reduced to
30 a negligible minimum; and which can be readily
installed in and removed from cabinets already
built.
Further objects are to provide an arrangement
having lower construction and maintenance costs,
35 which will be more rugged and durable, which
will be mechanically more simple and foolproof,
cans, or one or more of the cans of the lower
tier may be omitted and the space thereby made 10
available may. be used to accommodate loose
goods such as brick ice cream packages, frozen
confections or they like. In the drawings the
cans are designated 5, and a space for loose goods
is designated 6. In the illustrated example, seven
rather than eight half size cans or their equiva
‘ lents are used because the cans of the upper tier
are intended to be moved to provide access to
the cans or space in the lower tier, and to accom
modate such movement a blank or unoccupied 20
space equal to the volume of‘one can must be
provided in the upper tier. This unoccupied
space is designated ‘I in the drawings.
To support the cans of the upper tier a series
of trays or equivalent means 8, one for each can 25
of the upper tier, is provided. Each of these
supports, three in number in the illustrated em
bodiment, is mounted on means permitting the
support to be swung longitudinally of the cabi
net from a position directly above one of the 80
lower cans to a position directly above the next
adjacent lower can, and the character of the
mounting means is such that the path of move
ment of the support is arcuate, with the low
points of the path at its ends and the high point 35
substantially midway between the ends. In the
and which will be more efficient and dependable _ illustrated embodiment the mounting comprises
'40
in discharging its intended functions.
For the purpose of illustrating the invention,
I have shown in the accompanying drawings, and
will describe hereinafter, an embodiment of the
invention which is at present preferred by me
since the same‘has been found in practice to
’ give satisfactory and reliable results.
In the drawings,
_

to show the interior of a cabinet provided with
an embodiment'of the invention;
Fig. 2 is a vertical longitudinal section;
50

of the supports and a form of mounting for
the support;

_ shown in Fig. 4; and

cabinet illustrating a step in the installation
60 of a device made in accordance with a particu
lar embodiment of the invention.
Referring to the drawings, the reference nu-v
meral I designates generally a cold storage cabi
net of. familiar form and widespread use in retail
legs 9, each having its upper end pivoted at I II
to a support and its lower end pivoted at Ii
to a member II, or to the side ?ange l3 of such 40
a member, which occupies a relatively ?xed po
sition on the cabinet floor. The member it’, as
best shown in Figs. 3, 4 and 5, may consist of a
central web I! having upturned side ?anges i3
and may be regarded as a sort of false bottom
for the cabinet. It is rendered relatively im
movable in the cabinet by snugly ?tting from
end to end and/or from side to side of the cabi
net, by abutting ?xed elements in the cabinet,
or otherwise. _ The distance between its side 50
?anges is approximately equal to the width of
the supports 8, so that the legs 9 lie in substan
tially vertical planes. Obviously, the pivotal
mounting of the legs permits the supports to be
swung longitudinally of the cabinet from left to
right or right to left as seen in Fig. 2, from a
canting of the legs toward one end of the cabi
net to a canting in the opposite direction. Obvi
ously also, the path of support movement is arcu
ate with its low points at the ends of the path 60
when the legs are canted and its high point
intermediate the ends of the path when the legs
are vertical. It will be appreciated that the
supports will tend to gravitate towardsthe ends

ings'2, the supports and the cans on them are
very stable because movement in one direction is
serted into the cabinet through an end opening 2
and transversely curved or bent at the notches

Fig. 6 until it is wholly within the cabinet. It is
sisted by gravity. Consequently hard frozen ice
then turned on its side, with the web M in a ver- '
cream or the like may be ‘dug from the cans by
tical plane, and is easily restored to plane, ?at
condition by a workman reaching in through any
of the openings 2 with suitable hand tools. Once
forcible thrusts in any direction and the cans will
not accidentally move. Inasmuch as the ‘only
rubbing of moving parts occurs in the pivots and
10 their bearings‘ where the mechanical advantage
‘is of a very high order, frozen condensation at
these points is of no consequence. The parts are
promptly freed as soon as movement of a sup
straightened out, it is laid ?at on the cabinet
?oor, and each assembly of support and legs is 10
mounted on it.
Studs and cotter pins are con
veniently used to connect the lower ends of the
legs to the side ?anges l3 of the member l2.
In Figs. 4 and 5 I have shown protectors or
shields I 9 which may be mounted inwardly of and
sudden freeing of the pivots would not result in ' closely adjacent the legs to protect loose goods in
accelerating movement of the support. Conse
the lower zone of the cabinet from injury by the
quently there is no danger of too forcibly swinging moving legs. The shields is may be mounted on '
the supports against each other or against the the same studs or pins which pivot the legs to the
port begins. Since this initial movement includes
the upward vector, against gravity, even a very
20 cabinet end wall even when the pivots are quite
solidly frozen.
.
‘
'
It will be understood that other mounting
means may be employed provided the described
arcuate movement of the supports be retained.
The supports themselves may take any con?
venient form. I have illustrated a sort of skele
ton tray 8 of generally rectangular plan having
upturned end walls l 5 spaced apart sumciently to
accommodate a can, preferably rather snugly but
without binding. From the ?oor of the support a
'downturned side ?ange it provides a desirable
stiffening element and aifords a convenient con
nection for the legs 9, which may be pin connected
to the ?ange l6 and-to the ?ange l3. Preferably
?anges l3.

'
In illustrating the invention hereinabove I have
shown it embodied in a cabinet having a single
row of can compartments. In such a cabinet the
supports swing longitudinally. It is obvious that
the invention might just as well be embodied in a
cabinet having plural rows of can compartments
set side by side, in which case the supports might
be arranged to swing transversely from one row
to another.
The foregoing explanation of a preferred em
bodiment of the invention has been given by way
of exempli?cation and not limitation. The in
vention is capable of being embodied in other and
further modi?ed forms and it is to be understood ‘
four legs are used for each support, one at each

incorporate the broad principles of the invention
.
'
Bumper buttons or the like ll of rubber or its
equivalent may be mounted to project slightly
from the outer surfaces of the support end walls
ill to cushion the impact of the supports against
each other and against the cabinet end wall.
Referring again to the false bottom l2, it will
be obvious that even when the supports are
mounted by means of the legs 9, the member~l2
might be dispensed with. For example, the lower
ends-of the legs might be pivoted directly to the
cabinet side walls. The false bottom I2 is useful.
however, in adapting the construction to installa
tion in already built cabinets, in which it would
be di?icult, dangerous or- impossible to perforate
the cabinet walls to receive the pivot pins. The

deemed within the scope and purview thereof.
