My invention relates to'the provision of means

the same time increase rather than decrease the
relation to refrigerators in general.

When the door of a refrigerator is opened and
immediately closed again, there is not much in
crease of heat due to in?ux of outer air and ef
?ux of cold air within the refrigerator. How
10 ever, upon holding the door open for longer pe
riods of time, this loss becomes more of a factor.
What happens is that the cold air flows out from
a door, which are distinctive, as well as having
The refrigerator of the mechanical type,- as a
illustrated, has a casing i which is insulated and
surrounds a compartment 2, in which compart
ment is located the refrigeration unit 3, having
ice trays It therein. This unit is located in the
upper part of the compartment so as to set up 10
proper circulation of air therein, to maintain the
entire compartment cold.

The door, as shown, has a body t, which has a
warm air from without flowing in at the top.
It is my object to impede the flowing of cold
air out of the bottom of the refrigerator by means

by a wall of insulated nature. In this hollow 15
chamber there is arranged a rack of open wire
of a plate which is movable and preferably
hingedly connected to the refrigerator across the
lower portion thereof and inside of the door
thereof. This plate willthen maintain a pool
for ready availability when the door is open.

It is my object, further, to make of this plate

I have illustrated my invention in connection
55 with a door which is constructed in accordance
ever, by articulating the plate at the bottom it 45
can be used as an article supporting tray. To
this end one way of arranging the structure will
be to place rubber bumpers/ill, it, on the outside
of the plate. which bumpers will rest upon the ,
breaker strip when the plate is turned down, and 60
hold the plate in a horizontal position.
The convenience, of being able to arrange ar
tlcles on the tray is apparent, but it has particu»
lar advantages at the bottom of ‘the food com
partment because of its use in relieving conges- 55 i
tion of articles there, while removing or insert
ing others.
The plate when erected will probably not be

the door compartment. Also, if shelves were
l6‘ placed on the inside of a door, rather than in a
' compartment in a recess therein, the presence of
the plate would assist in setting up a di?'erent
current of cold air washing the door from that
which moves through the body of the refrigerator.
So far as saving in loss of cold air when open
ing the door is concerned, it should be noted that
the easy way for cold air to get out of the food
compartment is at the bottom, and that it is
at the bottom where the coldest air is normally
found. The plate not only impedes ?ow of cold
air out of the refrigerator which drains the cold
est portion of the compartment, but it greatly
impedes the loss of cold air from above because
of the air currents within and without the box
tending to maintain themselves.
Having thus described my invention, what I
claim as new and desire to secure by Letters Pat
eat, is:—
a temporary ‘shelf.
