ICE REFRIGERATOR
Carl Edward Harry Frykdahl, Duluth, Minn, as
Ilgnor to The Ooolerator Company, Duluth,
Minn, a corporation of Minnesota
Application June 18, 1936, Serial No. 85,875
90laims. (01. 62-31)
This invention relates to ice refrigerators and

its general object is to facilitate the operation of
Fig. 3 is a_ sectional view of the rack on the
introducing a cake of ice into the ice compart
line 3-4 of Fig. 1;
ment and upon the ice rack for initial icing and
Fig; 4 is a detail enlarged sectional view;
r; for re-icing.
Refrigerators are now being made with the ice
supporting bars of the ice rack located in a plane
below the sill of the ice compartment door so that
when the cake of ice in use has melted down
11, to or about the level of the sill a fresh cake of
ice can be slid into place on top of the cake then
in use. In one type of refrigerator for which my
invention is adapted the ice rack is located be
tween the ice compartment and the food com
l5 partment, and the circulation of air in the food
compartment contacts the ice at the bottom of
the cake and the cake melts level, or substan
tially level, at the top so that if care is exer
cised in re-icing as soon as the top of the cake
‘ is at or about the level of the door sill the fresh
‘20 cake can he slid into place very easily on the
cake in the ice compartment. The rack bars are
located below the level of the door sill and in
re-icing the cake may be left partly supported
25 on the top of the front rail of the ice rack and in
a tilted position on the ice cake in the refrigera
tor. In initial icing the ice cake may be unevenly
placed on the ice rack bars and left in a tilted
position on the ice rack, partly resting on the
g front rail of the ice rack, or the cake may be
slightly oversize and left in a tilted position.
It is desired to have the ice cake rest ?at upon
the ice rack in initial icing, or upon the ice cake
remaining on the rack in re-icing, especially in
refrigerators of the under-ice circulation type,
one form of which is shown in my copending ap
plication Serial No. 69,802, ?led March 20, 1936.
The object of my invention is to insure that
the cake of ice introduced into the ice compart
4
ment in initial icing or in re-icing shall be received and supported on the ice rack in a level
position.
Another object is to provide a rack having rack
bars located below the level of the door sill of
d the ice compartment with bars extending from
front to rear thereof and forming skids to receive
the ice cake and to support the ice cake tempo
rarily above the other rack bars.
A further object is to provide means where
by my invention can be applied readily to refrig
erators now in use.
In the accompanying drawings—
Fig. l is a vertical sectional view of a portion
of a refrigerator showing my invention embodied
55 in the rack thereof;
Fig. 5 is a sectional view of a rack showing my 5
invention applied thereto;
_
Fig. 6 is a sectional view on the line 8-. of
Fig. 5i and
»
Fig. 7 is a perspective view of the attachment
employed for embodying my invention in racks 10
now in use.
Referring ?rst to Figs. 1-4, 8 indicates a refrig
erator cabinet having an ice compartment 9 and
a door l0 therefor, and a food compartment H
and a door I 2 therefor. A front ledge l3 and a 15
back ledge H are arranged at the front and at
the back of the cabinet between the ice compart
ment and the food compartment and below the
level of the sill ii for the ice compartment
door Ill.
The ice rack comprises a front rail I 8, a back 2°
rail l1, and a plurality of parallel rack bars l8
secured to and supported on the front and back
rails. ‘The ice rack is supported in the cabinet
upon the ledges i3 and I 4 with the top of the bars
l8 located below the level of the sill I5. The front
rail inclines forwardly and is made of sheet metal
which is bent over to provide a rounded top It’
located inward of the sill and preferably just
a little above the level of the sill. The front
rail of the refrigerator provides a convenient skid
rail in introducing the ice cake into the ice com
partment. Keepers is are fastened to the back
wall of the cabinet and engage openings 20 in
the back rail I‘! to prevent the rack from tilting 3,.
upward at the back when an ice cake is skidded
over the front rail into position on the ice rack
or upon a reduced cake remaining upon the rack.
Modern ice refrigerators are made with ice com
partments and doors of proper dimensions to re
"
ceive ice cakes of predetermined weight which 40
are, generaly speaking, of predetermined dimen
sions. It is important that the ice cake should
melt evenly and maintain a substantial level at
the top and that the‘ refrigerator should be re
iced by the introduction of a fresh cake before
the ice in the refrigerator has been exhausted and
while a reduced cake of su?icient thickness to
cover the ice rack remains. When the top of
the ice cake reaches the level of the door sill it
will indicate time for re-icing and the thickness 60
of the reduced cake will furnish ample margin of
time for this purpose. The rack bars are made
of metal and penetrate the ice cake, forming ice
?ns between the bars, and if the body of the cake 55
2
2,118,185
completely melts away the ice fins would be sep
arated and ?nally drop through between the rack
bars into the usual drain pan, and waste ice; but if
re-icing is done before the body of the ice cake
has completely melted away and while the reduced
cake is an inch or more in thickness and the fresh
cake is placed ?atly and evenly on the reduced
cake, there will be an adherence between the re
duced cake and the fresh cake sufficiently to pro-.
v10 duce a continual normal operation without sep
aration and dropping of the ice ?ns when the
body of the reduced cake is completely melted.
For these reasons it is important, as before stated,
that the fresh cake should be placed squarely and
15 ?atly upon the rack in initial icing and in re-iclng.
The dimensions of the ice cake and of the ice
compartment and the door therefor, with a little
care on the part of the iceman, insure the square
positioning of the ice cake in the ice compartment,
20 but because the rack bars are located a substan
tial distance below the level of the door sill it is
possible to initially ice or to re-ice and leave
the cake tilted rearwardly in the ice compartment.
And this tilted position may not be readily notice
strip 24 has a ?ange 24’ which rest upon the rack
bars 21 whereby the frame is supported upon
the rack, and the frame has slots 28 to engage
keepers which are provided on the back wall of
a refrigerator cabinet to project over the back rail in
of the rack bar to keep it from tilting up at the
back when an ice cake is skidded into the ice com
partment over the front rail.
In both forms of my invention the rack bars
and the attachment are made conveniently of
galvanized sheet metal. The rack bars are shown
in one form which has been found satisfactory
but the invention may be used with rack bars or
other forms and with racks differing otherwise
in construction than herein shown and described.
The skid bars receive and support the cake of ice
in level position for initial icing and, if they are
exposed, for re-icing, and they insure that the
ice cake will be positioned levelly with respect to
the ice cake when placed in the ice compartment. 20
I have shown the invention as it may be em
bodied originally in an ice rack and as it may be
adapted by attachment to an existing rack, but
‘I do not limit the invention to the particular
It is form, construction and arrangement of parts 25
objectionable to have the ice cake tilted in the ice shown'and described and reserve the right to
compartment directly upon the rack or upon a make any changes necessary or desirable to adapt
reduced cake on the rack because the desired the invention to different kinds and sizes of re
frigerators and for other purposes within the
under-ice circulation will not be properly main
30
30 tained and the cake will melt unevenly and more scope of the following claims.
I claim:
rapidly and the e?iciency of the refrigerator is
1. An ice rack for refrigerators comprising a
likely to be impaired.
I provide the rack with skid bars 2| which ex ‘ plurality of parallel rack bars, and a pair of skid
tend in parallel relation from front to back of the bars arranged with their tops parallel with and
rack. The top of these skid bars is preferably above the rack bars to receive and support a cake 35
about the level of the sill of the ice compartment of ice.
2. An ice rack for refrigerators comprising a
door and of the top of the front rail and back
rail of the rack. However, I prefer to have the plurality of rack bars secured together in sub
top of the front rail of the rack which provides stantially parallel relation, certain of said rack
bars being spaced apart and extending above the 40
40 a skid for the ice cake slightly above the door sill
and the skid bars 2|, as shown in Fig. 1. The tops of the other rack bars with the tops of said
front rail thus provides a support for the ice cake certain bars in a single plane.
3. An ice rack for refrigerators comprising a
while it is being inserted in the ice compartment
and thereby protects the sill from damage from front rail and a back rail, rack bars secured to
the cake and facilitates placing the cake properly said rails, the tops of certain of said rack bars 45
being adjacent the top of the front rail and the
on the rack.
The skid bars can be made conveniently, as tops of the other rack bars being located below
shown in Figs. 1-3, by increasing the height of at the top of the front rail and the tops of said cer
least two of the rack bars, and when the ice cake tain rack bars.
_4. An ice rack for refrigerators comprising a 50
50 is located upon these two skid bars 2| in initial
icing the skid bars will quickly melt into the front rail and a back rail, and a plurality of rack
cake until the latter is resting upon the other bars secured at their ends to said ‘rails and ar
bars l8. In re-icing the fresh cake will rest upon ranged in substantially parallel relation, cer
the skid bars 2| which rapidly melt therein until tain of said rack bars having their tops adjacent
55 the fresh cake rests upon the reduced cake on the tops of the said rails and the tops of the 55
the bars l8. These skid bars 2i facilitate the other rack bars being located adjacent the bot
operation of positioning the ice cakes squarely in toms of said rails.
5. A refrigerator comprising an ice compart
