5 particularly, to a» novel improved form of door for
such refrigerators adapted to provide auxiliary
supporting means for articles and materials de
sired to be stored within the refrigerator.
It has been heretofore known to provide article

It is an object of the instant invention to pro
20v vide a novel structure for closing the main in
terior or chamber of a refrigerator which is ar
ranged to- provide auxiliary supporting means
for articles and materials desired to be stored
within the refrigerator, but which is further pro
vided with means, manipulatable at will, to give
access to such auxiliary supporting means with
out necessity for opening the main refrigerator
door per se. -

Another object of this invention is to provide
30 a novel means for normally communicating cold
air to and around the auxiliary supporting means,
together with means to automatically cut off such
communication when such auixiliary supporting
means are opened to access from the exterior of

Referring to the drawings, the reference char
acter l0 indicates the main body or housing of a
refrigerator which is provided in' its front wall
with a main door opening il giving access to the
interior chamber i2 of the body or housing. Lo-'
cated within the interior chamber 12 is a suit
able cooling unit i3 of a mechanism refrigerating
system. Also arranged in suitable disposition
within the body or housing interior 12 are a plu
rality of shelves M for the support of articles 25.
and materials desired to be stored within the re
refrigerator. It will be understood ‘that the detail
construction of the refrigerator body or housing
may be in accordance with known standard prac- '
tices, whereby desired heat insulating construc
tion and effects are attained.

Supported on the front wall of the refrigerator
body or housing in, by suitable hinges i5, is a
main or primary door member l6 adapted to nor
the main door, whereby escape of cold air. from
mally fit into the door opening'i I, thereby to close
temperaturetherein is successfully avoided.
Cooperative latch means ll, of any convenient
known form, is provided to hold the door member
l6, closed. Around its periphery the door mem-,
ber I6 is provided with a rabbet ?ange Hi to 40
the refrigerator 'interior' with undesired rise of . . the interior chamber l2 of said body or housing.
Other objects of this invention, not at this time
more particularly enumerated, will be understood

Fig. 4 is a fragmentary outer face view or front
elevation of a refrigerator equipped with‘ a modi
fled arrangement of the novel door structure;
55 and Fig. 5 is a vertical longitudinal sectional view
break the joint between the door member and the _
marginal portions IQ of the body or housing door
opening ii. Preferably the inner or abutting
face of said rabbet ?ange i8 is provided with a
gasket ‘strip 20 suitably secured thereto, and
adapted to seal the joint between the door mem
ber and marginal portions of the~ door opening
when the former is closed. At its interior side the
door member is provided with a plurality of re
cesses 2 I which are covered by a suitably attached‘ 50
‘back-plate 22, so as to be partitioned by the latter‘
from the interior chamber I! of the refrigerator
housing. In Fig. 3 of the drawings three recesses‘
2| are shown, it will be understood however that,
according to the size or capacity of the door mem 55
2
2,186,558
ber l3, the number of recesses may be increased
or decreased. Communicating with the respec
tive recesses through the body of the door mem
ber I3 from the exterior face or side thereof are
access openings 23. Each access opening is pref
erably bounded by an internally. projecting rabbet
?ange 23’. Manipulatable means are provided
for closing and opening each access opening, said
means preferably serving to carry suitably formed
10 article or material supporting shelves or racks.
In Figs. 1 to ‘3, the means for closing and
‘opening the access openings 23 is arranged in
the form of outwardly opening vertical swing
auxiliary or secondary doors 24; each being
15 bounded around its periphery with an externally
projecting rabbet ?ange 25 to cooperate with the
internal rabbet flange 23' of the access opening
served thereby so as to form a break joint.
Pref
erably the inner abutting face of the rabbet flange
20 25 of each secondary door 24 is provided with a
gasket strip 28 suitably secured thereto, and
adapted to seal the break joints when said sec
ondary doors are closed. Each secondary door
24 is pivotally connected at its bottom-margin
to the main or primary refrigerator door member
l3 by suitable hinge elements 21; and each sec
ondary door is releasably held in normal closed
position by any suitable form of manipulatable
latch means 23, which is mounted adjacent to
its upper free edge and which is provided with
an operating handle-29. ' Each latch means 28
is adapted to cooperate with a ?xed latch piece
30 mounted on the main or primary refrigerator
door member l6. Suitably a?‘ixed to the inner
35 face of‘ each secondary door 24 is a shelf or tray
3| for the support of articles or material desired
to be deposited within the recesses 2|. The back
plate 22 of the main or primary door member i6
is provided with openings 32 respectively pro
viding communication between the recesses 2|
40 and the interior chamber H of the refrigerator
body or housing “I. Cooperative with each said
opening 32 isa closure plate 33 which is pivotally
connected by spring hinge members 34 to the
back-plate 22 so as to close the opening 32, while‘
nevertheless being yieldable to opening movement
toward the interior chamber |2 of the refriger
ator body or housing Hi. It is preferable to pro
vide a sealing gasket 35 around each opening 32,
which gasket is engageable by the closure plate
60 33 when in closed position, to thereby effect a
tight Joint. Fixed on the recess facing side of
each closure plate 33 is a projecting push-piece
33. When a secondary door 24 is closed, the
shelf or tray 3| carried thereby will strike the
55 push-piece 33 and thus impart an opening move-'
ment to the closure plate 33, thus opening com
munication between the interior chamber | 2 of
the refrigerator body or housing Ill and the re
cess 2| served by the thus closed secondary door
Under these circumstances cold air from
the interior of the refrigerator is admitted to
that cold air from the latter cannot escape and
be replaced by warm exterior air resulting in
wasteful and undesired rise of temperature with
in the main interior of the refrigerator. From
the above it will be apparentthat each of the
plurality of recesses with which the primary door
member l6 of the refrigerator is provided is sub
ject to selective individual access from the ex
terior of the refrigerator, without disturbing 're- _
frigeration conditions in either the other recesses
or the main interior of the refrigerator.
The secondary doors 24 may be modified for
operation in manner other than the above de
scribed vertical swinging arrangement thereof.
For example, the secondary doors 24 may be ar 15
ranged for movement in the manner of hori
zontally sliding drawers, as shown in Figs. 1 and
5. When so arranged, telescoping sliding ex
tension brackets 31 may be utilized in place of
hinges, and a latching means 38 adapted for top
and bottom latching effect may be employed to
hold the doors 24 in normally closed relation to
the main or- primary refrigerator door member it.
In other respects the construction is substan
tially the same as already above described. As
a further example of possible variation in the
manner of mounting the secondary doors 24,
thereis shown in Figs. 6 and 7 of the drawings,
an arrangement providing for horizontal swing
ing movement thereof. In such arrangement, 30
hinge elements 39 connect one vertical end of the
secondary door 24 to the main or primary refrig
erator door l6, and cooperative latching means
40 are provided at the opposite or free vertical
end of the so arranged secondary door.
Referring to Fig. 8 of the drawings, there is
shown therein a modified arrangement of means
for automatically opening and closing commu
nication between a recess 2| of the primary door
member I 6 and the main interior of the refrig 40
erator when a secondary door 24 is manipulated.
In this modi?ed arrangement, the‘ back-plate 22
on the primary door member I6 is omitted, but
pivotally suspended from the free side of the
shelf or tray 3|’ carried by the secondary door
24, by means of hinge elements 4| is a closure
plate 42. In operation, when the secondary door
24 (which is of the vertical swing type) is swung
open, the pivotally suspended closure plate 42
is carried upwardly and inwardly into the recess 50
2| until it abuts the marginal portions of the
rabbet ?ange 24 surrounding the access opening
23. thus closing the latter against escape of cold
air from or entrance of warm air into the main
interior of the vrefrigerator, all as shown by
broken lines in said Fig. 8 of the drawings.
Preferably a sealing gasket 43 is provided around
the access opening 23 to be engaged by the abut
ting closure plate 42, to thereby form a tight
joint when the latter is closed over said access 60
opening 23.
It will be obvious that many changes, other
said recess 2| for circulation therein and around , than'those‘above suggested, could be made in
the articles or materials supported therein by
the shelf or tray 3|. when, however, it is desired
to gain access to the articles or materials, and
to such end the secondary door 24 is opened and
swung outward, the shelf or tray 3| is carried
away from the push-piece 33 by the opening
movement
of the secondary door 24, and conse
70
quently the spring hinge members 34 will press
the closure plate 33 into closed relation to the
back-plate opening 32, thereby cutting 011 com
munication between the thus outwardly opening
75 recess 2| and the interior of the refrigerator, so
the above described constructions, and many ap
parently widely different embodiments of this
invention could be made without departing from
the scope thereof as defined by the following
claims. It is therefore intended that all matter
contained in the above description or shown in
the accompanying drawings shall be interpreted
asillustrative and not in a limiting sense.
