19 Claims.
This invention relates to household and com
mercial ice refrigerators, and the principal object
of the invention is to provide a novel ice grid
which will increase the efficiency of the ice for
5 ~ refrigeration purposes, the grid exposing only the
in connection with a refrigerator casing of the
“one door” type having side walls A, top B, bot
tom C and'a. back D, and having a single door
E at, the front which when opened gives access’
to the ice compartment above the grid, and like
wise access to the food compartment disposed‘
below the grid. However my grid may be used
in connection withvother types of ice refrigerators
bottom surface of the ice block to the circulating
air within the refrigerator casing by a unique
arrangement of parallel metal plates disposed
having two or more doors, also with refrigerators
edge wise to the ice block, which arrangement
10 considerably increases the cold surface area along
which the air passes, the air currents rising at
the sides of the refrigerator casing and entering
the grid from the end and passing along the grid
plates to the center of the grid from whence the
having certain doors installed for icing. pur
poses only.

The ice compartment, in' the upper portion of‘
the casing, is shown as provided at‘ the‘ sides

'
A further object is to provide a grid having
plates increasing in depth from side to center,
30 and provided with recesses at'their centers, the
walls of which serve to divert the drip of ice melt
age into aidrip pan disposed below the grid; said
recesses also serving to provide an unobstructed

casing, the-plates ‘(d not only serving to stiffen ' ‘
the shelf supporting "flanges lb of the bracket '

9d is a plate 9e extending downwardly to meet
and stiffen the ?ange 9b which forms a shelf for
supporting the front end of the drip pan 6 as
shown in Fig. 3.
Drip pan 6 is preferably of the insulated type
and consists of upper and lower ?anged sheet
lar recess 4b for the purpose of permitting con
densation on the plate 4 to be carried to either
side of the recess and fall uponja drip pan 6
below the grid, hereinafter described.
The shorter grid plates 3, as shown in Figs. 1
and 2, are only about half the length of the
plates 4 and have their ends 3a (Fig. 1) cut on a
bevel sloping upwardly towards the center of the
casing. The plates 3 otherwise have the same
metal members 6a, 6b with. a layer of insulation
shape and con?guration as the corresponding
60 therebetween, the upper pan. 6a serving as
portions of the plates 4, and are likewise provided‘ ‘the lower half of the air ?ue and also as the
with relatively large triangular recesses in their
lower edges corresponding in size and shape with
drip pan.. The lower pan 6b merely serves to
protect the insulation 60 and to present a clean
metal surface at the top of the food compart 15
ment. The drip pan 6 is spaced away from the
side walls A-A of the refrigerator casing and is
15 the recesses 41) in the longer grid plates 4. ,
Extending across the tops of the assembled
plates 3 and 4 at the center of the grid and dis
posed at right angles to the plates is an inter-. provided with a slot 6d at its center which slot
locking bar I serving three‘purposes; ?rst, to ‘ extends the full length of the grid; and has a
?ange 6e around its edges retaining the meltage 20
ice grid in placing the block in the'ice compart
water. To assist the ?ow of air along the plates
20 permit the block of ice to initially slide over the
ment; second, to resist any tendency of the ice
block to shift laterally within the ice compart
ment in event the grid is not level; and third, to
25 tend- to split the ice block into two parts which"
will separate and slide laterally away from the
de?ector plate 2 hereinafter described. The in
terlocking bar I may be secured to the-plates 3
and 4 in any desired manner preferably by notch
30 ing the lower edge of the same to receive the up
per edges of the plates 3 and 4 which may then ‘
be welded thereto. Obviously the upper edges of
the plates 3 and 4 could be notched instead of bar
I, if desired.
The de?ector plate 2 extends transversely of
35
3 and 4 and also to assist in carrying off drainage
water the sections of the drip pan at opposite
sides of slot 6d slope downwardly towards the
center of the casing. The front end of the drip
pan 6 is supported upon'the ?ange 9b of the
center rail 9, while the rear end is supported by
angle clips secured to the rear wall D of the re
frigerator casing, the drip pan 6 sloping generally
downwardly toward the rear of the casing (85 30
shown in Fig. 3) so that the meltage water will
?ow into the drain tube 8.
,
The air circulation is illustrated by the arrows
in Fig. 1, the warmer air passing upwardly along .
the side walls A—A of the food compartment, and
w the grid and serves three purposes; ?rst, to di
inwardly towards the center of the casing in the 35
vert the meltage water to either side of the ?ue ' air ?ue formed between the bottom of the block
opening 6d; second, to serve as the upper part of
the air ?ue; and third, to support and locate the
40 shorter plates 3 of the grid; and as the de?ector
plate is secured to all ‘of the plates 3 and 4 a very

along the grid plates 3 and 4, the major parts of
the surfaces of which plates are exposed to the

At the rear end of the grid is a plate 43: (Fig. 3), 3 grid inasmuch as the ice chamber itself is soma
the lower end of which is ?anged downwardly and
rearwardly'as at 41,! and extends under the lower
edge of the lining 1 on the back wall D of the
casing; while at the front end of the grid is
a plate 4w having its lower end ?anged down
wardly and forwardly as at 4.2 to extend up toa
portion of the center rail which is disposed across
the front of the refrigerator casing.

The center rail preferably comprises a plate 9
65 extending across the entire front of the refriger
ator casing between the side vwalls_A---A'at the
height of the ice grid, the plate having its upper ,
edge ?anged obliquely downwardly as at 9:; tog
wards the ice grid to assist in maintaining the
70 block of ice centered on the grid.
The. lower“
end of the plate 9 is ?anged inwardly as at 9b.
Below the lower edge of the ?anged portion 9a
is a plate 90 which forms a continuation of the .
?ange 9a and slopes downwardly and rearward7
75 . ly, and has its lower edgeflanged downwardly as.
what larger than the blocks of ice. Obviously 55
these inclined surfaces will tend to forcev the ice
block directly over the grid, as will also the
downwardly and rearwardly, plates 9a, 90 of the 7
center rail 9 which form continuations, of the
60
bracket portions ‘la.
vThe ice grid is illustrated herein in connection’
with a so-called “one door” refrigerator, although 1
_ it is obviously applicable for use in refrigerators
. of two or more doors, and also to refrigerators ‘
having certain doors installed for icing purposes
only.’
