This invention relates to ice trays or the like
The lower end of lever I8 is rounded and eccen
for use in household refrigerators, and constitutes trically pivoted to the lower rounded end of a

tray body I2 is ?lled with water or other matter,
10 advantages thereof, will become apparent from
this speci?cation, and of which Fig. 1 is a frag
mentary front view of a cooling unit and an ice
tray embodying the invention placed therein, and
Fig. 2'is a fragmentary sectional view taken on
line 2-2 of Fig. 1 illustrating more clearly parts
of the device provided on the tray.
Referring to the drawing, an evaporator or cool
In the use of the above described device, the '
to be'frozen and inserted in the cooling unit I0
of the refrigerator with which the tray is used.
With the tray positioned in theycooling unit heat 15
is removed from the tray bottom through the
shelf,'due to the production of cold by the cooling
unit, whereby any moisture between the tray bot
tom and the shelf is frozen, thus ?rmly uniting
20 ing unit I!) of a.‘ household refrigerator ‘ (not
. the parts. When it is desired to remove the tray
shown) is refrigerated in any desired manner.
The cooling unit I0 may be provided with one or
more tray receiving compartments, only one of
which is shown, in which an ice tray II is placed
25 for freezing the contents of the same. The tray
I I includes a receptacle body I2, at the front end
of which is provided two bent over extended por
tions or abutments to which a tray front I3 may
be secured by bolts or other fastening elements
I5. This structure is formed at the time of stamp
ing the tray, the material at each side of the tray
being cut along the line indicated at I6 in order
to provide a triangular reenforcemen't at each
front outer corner of the tray. The tray front
35
I g is formed with a handle or hand-grip portion
I
.
with its contents, the handle 20 of lever I8 is
moved downward whereby the lower rounded end
.of lever I8 is rotated eccentrically with respect
to the lower rounded end of the bracket 2 I. With
such eccentric movement of the lower rounded
end of the lever I8 the lower end of the lever
bears against the surface of the shelf I1 and

exerts a separating force between the tray body
I2 and shelf I'I. When the ice bond between the _
tray and shelf is broken and the ?nger-grip 28 30
is released, the spring 22 returns the parts to
the position shown in Fig. 2, whereupon the hand
grip I4 can be grasped and the tray removed
from the cooling unit.

,
In view of the foregoing, it will be seen that 35
an improved device has been provided for facill~
tating the removal of ice traysfrom cooling units.
The lower rounded end of lever I8 is normally

tion or shelf ll of the cooling unit with the broad

bond between the bottom of the tray and the shelf this construction the lower end’ of the lever I8,

together with the bracket 2|, forms 'a leverage 45

In accordance with this invention an improved. force is provided to separate the tray body from
device is provided for breaking the ice bond which
is formed between the bottom of a tray and the
50 shelf of a cooling unit upon which it is placed.
Referring to Fig.2, the device shown includes a
lever or bar I8 which extends through a slot l9
formed in the hand-grip portion I 4 of the tray
front and is provided with a curved upper end 28
55 to provide a ?nger-grip for actuating the device, 7
the support.

Although a particular embodiment of the in
vention has been shown and described, it will be 50
apparent that various modi?cations and changes
may be made without departing from the spirit
and scope of ‘the invention.
What is claimed is:

spaced parallel relation with one of said end
walls, said front plate having a vertical slot and
being formed to provide a handle for the tray, a
lever having one end projecting through the slot
in said front plate and the other end pivotally
connected to’ said tray adjacent the lower front
edge thereof, a spring for normally holding the
1
lever against the top of said‘ slot, and the pivoted
end of said lever being formed as a cam which
engages a tray supporting shelf when rotated by
movement of the projecting end of said lever
downward in said slot against the action of said
spring to loosen any ice bond there may be be
tween the shelf and the bottom of the tray.
