In refrigerators as heretofore constructed the
temperature of the .entire interior rises nearly
to that of the exterior due to the spilling of the
cold air from the refrigerator and its replacement
5 by warm air from outside whenever the refriger
ator is opened for access to the contents. Such
frequent elevation of interior temperature inter
feres with proper food preservation and results in.
considerable waste of ice or power.
The principal object of this invention is to pro
vide a refrigerator constructed' in a novel and
convenient manner, which may have drawers that
can be opened and closed Without loss of cold air.
More specific objects and advantages are ap

had to the accompanying drawings illustrating a
‘ preferred embodiment of the invention.

These specific drawings and the >specific de
scription that follows are to disclose and illus
trate the invention, and are not to impose limita
tions upon the claims.
The refrigerator may be made in two or more
sections to facilitate manufacture, transportation
and assembly. One of the sections may be in the
form of a closure section Ill, preferably located at
35 the bottom of the refrigerator, so that the other
section or sections rest upon it. In the form of
refrigerator illustrated there are three inter
mediate sections II, I2, I3 resting upon the bot
» tom section II'I, and another closure section at the
The top section Il may be provided with means
for cooling the air in the refrigerator, such as an
evaporator I5 operated by a refrigerating unit
located in a rear compartment I6.

The sections are preferably held together by

most of the ñanges 2l are omitted for the sake
of clearness.
Two apertures 28 may be provided in the top 25
of the compartments for circulation of air that
is bypassed by means of bañles 29. The baffles
may have strips 30 of ñexible material mounted
along their upper edges, fitting against portions
of the section above, which portions in this case
are the bottoms of similar compartments .in the
section above. 'Whatever may be the type of con
struction selected, the second section should co
operate with a compartment of the first to es
tablish circulation of the air of the refrigerator 35
through the compartment.
In the third intermediate section I3, compart
ments 3| may be provided having no apertures,
with walls of thermally conducting material.
The interior of these compartments thus may be
kept cool while food is stored in them out of con
tact with the air of the rest of the refrigerator.'
In order to guide into the proper channels air that
has circulated around and through the compart
ments, the lower edges of _the inner sheets 20 45
