My invention relates to freezing trays for re
frigerating machines and more particularly to
partition elements -for such trays.
It is an object of my invention to provide an
improved removable partition element of rugged
construction embodying . an arrangement
for
applying heat to the 4ice cubes and freezing tray
to thaw the frozen bonds therebetween -in a
` simple and eñicient manner.
I accomplish this
10 by utilizing a partition element removably car
ried by a freezing tray in good thermal contact
therewith. The partition element comprises
spaced apart walls having a substantially sinuous
configuration and formed of a folded sheet of
15 'metaL the edges of the sheet being rigidly se-v
cured together to define a tubular passage in the
partition element, which tubular passage is em
» ployed for applying heat to the walls of the par-
and the longitudinal and transverse portion of
the partition element cooperate with the freez
ing tray to form a plurality of ice block molds.
The marginal edges I5 of the sheet extending
along the transverse portions of the Walls at 5
each end of the partition element are extended
somewhat and curved inwardly to provide sup
porting feet I8 at each end of the partition ele
ment. The marginal edges I5 of the sheet ex
tending along the transverse portions of the 10
walls lying intermediate the ends of the partition
element are extended somewhat beyond where
they are secured together and flared outwardly
in opposite directions to provide supporting feet
I9 intermediate the ends of the partition element. 15»
These feet i8 and I9 have flattened lower sur
faces which directly engage the bottom of the
freezing tray I0 in good thermal contact there
with >and support the partition element. A'
tubular' passage 2U is formed between the spaced 20
apart walls I2 and I3 and extends throughout
scription proceeds, and the features of novelty -the
length of the sinuous partition element. Po
which characterize my invention> will be pointed
out with particularity in `the claims annexed to sitioned in the extending tubular passage 20 is

For a better understanding of my invention ` ' electrical

Fig. 3 is an enlarged sectional'view of a portion
of the end of the partition element shown in Fig.

tion of the partition element shown in Fig. 2;
and Fig. 5 is a fragmentary side elevation, partly
in section, of a modified form of the partition
element shown in Figs. 1 and 2.
Referring to the drawing, in Fig. 1 I have
shown a shallow rectangular metal freezing tray
I0 containing a, removable partition element Il.
The partition element I I includes spaced apart
Walls I2 and I3 formed of a single sheet of metal
of high thermal conductivity such, for example,
as aluminum or copper folded at I4.
The mar
ginal ends I5 of the sheet are rigidlysecured to
gether preferably by the fusion of metal, that is,
by line welding, soldering or the like as best
shown in Figs. 2 and 3. The spaced apart walls
I2 and'l3 of the partition element are of sub-`
stantially sinuous configuration and include a
plurality of longitudinal and transverse extend
ing portions I6 and I'I, respectively. The dimen
sions of the partition element II are such that
>the same snugly fits into the freezing tray Il]
in the bend It lying between the walls I2 and
I3, and one end of a tubular metallic elbow 23
is secured to the partition element about this
opening. The other end of the elbow 23 carries
an insulated bushing 25 in which spaced apart
electrical terminals 26 are embedded, as best
>shown in Figs. 3 and 4. vThe terminals 26 are
connected to the heating element 2| by insulated 35
leads 21 extending through the elbow 23 and the
opening 24 in the bend I4 lying between the walls
i2 and I3. The partition element || together
with the heating element 2| carried in the tubu
lar passage 20 therein comprises a rugged 40
unitary structure and is removable as a unit from
the freezing tray I 0.
In removing ice cubes or the like from the
freezing tray I0 the same is first removed from
»the surface of an evaporator of a refrigerating 45 'l
machine and placed upon a suitable support.
The terminals 26 supported in the end of the
tubular elbow 23 secured to the partition ele-y
ment are thenv plugged into a socket connected
to a source of supply. After a short interval of 50 ¿
time a sufficient amount of heat will have passed
from the heating element 2|, positioned in the
tubular passage 2U, through the walls I2 and I3
to thaw the frozen bonds between the sides of
the ice cubes and the walls of the partition elej 55 l

shown in Fig. 5 is constructed in a manner simi
lar to that shown in Figs. 1 to 4, inclusive, except
20
that the electrical heating element positioned in
the tubular passage 20 formed between the spaced
apart walls I2 and I3 is eliminated, and in the
opposite ends of the partition element openings
are provided in the bend I4 lying between the
25 walls I2 and I3. About these openings inlet and
outlet connections 30 and 3|, respectively, are
secured to provide fluid tight joints between the
connections and the tubular passage 20 formed
between the spaced apart walls I2 and I3 of the
30 partition element. 'I‘he outer end of the inlet con
nection 3|] is flared and provided with a retaining
bead 32 thereabout which receives and secures a
rubber receptacle 33 in place. In this form of the
partition element the frozen bonds between the
35 sides of the ice cubes and the partition element
and the freezing tray are thawed by conducting a
heating medium such as hot water, for example,
through the tubular passage 20. The open end
of the rubber receptacle 33 is connected to a
faucet or other source of supply of hot water.
The hot water is passed into the inlet connec
tion 30, flows through the tubular passage 20 ex

of said sheet being rigidly secured together to de

substantially sinuous configuration having trans
verse and longitudinal portions adapted to form
ice molds, means including said tubular passage
for applying heat to said walls, and means in

between the sides of the ice cubes and the parti
tion elements and the freezing tray have beenh
thawed the ice cubes are removed’as described
in connection with the form of the partition ele
50 ment shown in Figs. 1 to 4 inclusive.
It will thus be seen that I have provided a par
tition element embodying an improved arrange
ment for applying heat to the ice cubes, thereby
allowing the ice cubes to be removed from the
55 partition element and freezing tray in a simple
and efllcient manner. Also, the construction of
the partition element renders the same rugged
and cheap to manufacture.
While I have shown a particular embodiment
of my invention in connection with a rigid metal
lic freezing tray, I do not desire my invention to
be limited to the particular construction shown
and described and I intend in the appended
65 claims to cover all modifications within the spirit
and scope of my invention.
