Application March 23, 1936. Serial No. 70,344
3 Claims. (or. 312-189)
The present invention relates to improvements arrangement taken along line 4-4 of Figure 1,
in refrigerators and its principal object is to pro
vide means for reducing to a minimum the loss
of cold air when the door is opened for gaining
5 access to the contents of the refrigerator.
More particularly it is proposed to provide a
second or auxiliary door in addition to the con
ventional main door and to provide this door with
a number of openings and windows through
m which access may be gained to limited sections
of the refrigerator without exposing the entire
cooling chamber of the refrigerator to draft and
to exchange of cooled air with the outside tem~
perature.

it is further proposed to make the windows
and practically the entire area of ‘the auidliary
door of glass or- similar transparent and heat
insulating material so that the entire vcontents
of the interior of the refrigerator may be viewed
55% from the outside and selection made before any
part of the auxiliary door is opened.
It is further proposed to arrange the auxiliary
door in such a manner that it will in itself con
stitute a complete closure for the cooling cham
25 her of the refrigerator.
It is further proposed to provide drawers in
the cooling chamber and to arrange the auxiliary
door with openings through which the drawers
may be moved, the entire arrangement being
30 preferably such that the front walls of the
drawers lie in the plane of the auxiliary door and
cooperate therewith in forming a complete
closure for the interior of the refrigerator.
It is further proposed to provide a cooling
35 chamber of the refrigerator with shelves or par
titions for dividing the same into different com
partments and to arrange the window openings
of the auxiliary door in such a manner that they
substantially .register with the compartments so
that individual and separate access may be
gained to each compartment.
Further objects and advantages of my inven
tion will appear as the speci?cation proceeds.
The preferred form of my invention is illus
45 trated in the accompanying drawing in which
Figure 1 shows a perspective view of my re
frigerator with the main door open and the
auxiliary door closed,
Figure 2 a similar perspective view with the
50 main door open and the auxiliary door closed
but. with certain windows and a drawer open,

main door open and the auxiliary door partly
- open,

Figure 4 a vertical section through the door
and
Figure 5 a horizontal section takenalong line
5-5 of Figure 1.
While I have shown only the preferred form 5
of my invention I wish to have it understood that
various changes or modi?cations may be made
within the scope of the claims hereto attached
without departing from the spirit of the inven
tion.
‘
ill
Apart from the special features of the inven
tion the refrigerator 9 may be made in any con
ventional manner and the present invention has
no reference to the manner or means for cooling
the interior of the refrigerator.
As a rule a 25
large portion of the upper part of the refriger
ator is devoted to the reception of food and this
portion is hereinafter referred ‘to as the cooling
chamber 2. It is provided with shelves 3 where
by it is divided into different compartments ll 20
and a number of drawers 5 are arranged at'the
bottom of the chamber. Above the upper shelf
ii there is a special small compartment 6 in which
ice cubes are frozen in the conventional manner.
The cooling chamber is open in front and has 25
a beveled edge around the opening. A conven
tional heavy door 1 is hinged to one edge of the
opening as at 8 and has a projecting section 9
with a beveled edge ill adapted to be received
within the beveled edge of the door opening. 30
There is enough space between the beveled edges,
however, to accommodate the frame of the
auxiliary door H which constitutes the essential
feature of the present invention.
The door II has a beveled frame I2 of rela- 35
tively thin material and is hinged to the beveled
edge of the door opening as shown at l2’, so
that when both doors are closed the frame of the
vauxiliary door lies between‘the‘ beveled edges of
the main door and the door opening.
The door is provided with a plurality of win
dows l3 which are hinged'to the door frame l2 as
shown at l3’ and which are preferably arranged
in such a manner as to correspond to the different
compartments in the cooling chamber so that 45
access may be gained to the different compart
ments through the individual windows. Special
smaller windows are provided for the smaller
compartments on the upper shelf adjacent the
ice cube compartment and an opening I 4 is left 50
in the auxiliary door for the drawers of the
ice compartment and a large opening is provided
at the bottom of the frame 12, (see Figure 3)
for the drawers 5 so that the drawers may be
pulled out without opening the auxiliary door. 55

The drawers are preferably arranged in such a
manner that the front walls thereof lie in the
plane of the auxiliary door when the latter is
closed and completely ?ll the opening in the
door left for them.
The manner in which the invention works may
be readily understood from the foregoing de
scription. When it is desired to gain access to
the cooling chamber as a whole, both the main
10 door and the auxiliary door may be opened. But
for all normal operations, as for the insertion and
removal of food, the auxiliary door may remain
closed and form a closure for the cooling cham
ber though the main door is open. It ?ts tightly
around the edges so there is no draft. At the
same time the contents of the entire chamber
may be surveyed through the glass windows be
fore any of the latter are opened. After selection
has been made, the operator opens the window
20 through which the selected food may be with
drawn and since the window is small and the time
required for opening and closing it very limited
there will be very little exchange of air between
the inside and outside of the refrigerator. The
‘drawers 5 of the refrigerator and the ice cube
compartments may also be opened without open
ing the auxiliary door.
It is apparent that all conventional operation
means, such as spring means for opening the
doors, latches for closing them and electrical
means for releasing the latches may be applied
to both doors and the windows without the exer
cise of invention.
I claim:
1. In a refrigerator, a housing having a cooling
chamber for storing food, a drawer in the cooling
chamber, a door for closing the cooling chamber
and a second door inside the ?rst door having
an opening through which the drawer may be
moved, the drawer having a front wall cooperat
ing with the second door in forming a complete
closure for the cooling chamber and arranged
to permit the second door to be opened without
moving the drawer.
2. In a refrigerator, a housing having a cooling
chamber for storing food, a drawer in the cham 10
ber, a shelf in the chamber for dividing the same
into a plurality of compartments, a door for the
chamber and a second door inside the ?rst door
and having an opening through which the drawer
may be moved and movable windows through 15
which access may be gained to the individual
compartments, the second door being made to
coact with the drawer in forming a complete
closure for the cooling chamber and arranged to
permit the second door to be opened without 20
moving the drawer.
3. In a refrigerator, a housing having a cooling
chamber, a plurality of drawers in the chamber,
a plurality of shelves in the chamber for dividing
the same into a plurality of compartments, a door 25
for the chamber and a second door inside the ?rst
door and having an opening through which the
drawers may be moved and movable windows
through which access may be gained to the in
dividual compartments, the second door being 30
made to coact with the drawers in forming a
complete closure for the cooling chamber and
arranged to permit the second door to be opened
without moving the drawer.
