Application November 10, 1934, Serial No. 752.484
15 Claims. . (Cl. 312-189)
This invention relates to improvements in re
similar reference characters are employed to ‘
frigerator cabinets and particularly to improve
' ments in means for mounting and actuating the
doors thereof.
An object of the present invention is the pro
vision of a refrigerator cabinet including an im
proved mounting for the door and particularly
the sliding door.
'
Another object'of the invention is the pro»
vision of an improved sliding door mechanism
for refrigerators and the like in which the door
may be readily actuated without interference
from or interfering with other parts of the re
frigerator.
'20
.
A still further object of the invention is the
provision of a sliding door refrigerator cabinet
in which the sliding door is so mounted as to
provide ready access to the interior of the cab
inet and in which the door may be positioned to.
give free access to the interior of the cabinet
for cleaning purposes and the like.
I
Other objects and advantages of the present
invention should be readily understood by ref
to the following speci?cation when con
25 erence
sidered in connection with the accompanying
drawings and forming part thereof, and it is
to be understood that any modi?cations may
be made in theexact structural details therein
shown Without departing from or exceeding the
denote the same or similar parts.
As was noted. above this invention has for
its prime object the provision of an improved
mounting for sliding doors as used on refriger
ators and the like. In prior structures the slid
ing doors were forced to travel through pre~
formed trackways'which in the main failed to
‘account for the seal strip and like obstructions
in the cabinet thereby frequently setting up con 10
siderable friction to the movement of the doors
and-‘preventing same from being operated ef
?ciently. By the present invention the door,
prior to its operation in a. vertical direction, is
spaced from the said seal strip and other obstruc
tions whereby it may be actuated in its normal
manner with the least amount of effort.
Speci?cally this invention comprises a cabinet
l0 having formed at the upper end thereof the
refrigerated or food compartment ii and at the
20
lower end the refrigerant or machinery com
partment l2. As seen in Fig. 1 these compart
ments are formed between two vertical walls I8
and H which walls are thickened to provide suit
able insulation for the refrigerated compartment
as seen at l5 and IS in Fig.- 8.
Supported by .25

ment H ,are- the supporting shelvesl‘i and I8

Throughout the several views of the drawings
The recess 21d extends the full height of the
cabinet and encloses not only the seal strip 26 50
and door 21, but also the supporting means
be further described in
detail. As will be seen in Fig. 8, the outer sur
face of the seal strip is considerably below the 55
outer end of the channel or recess 21a and it is
this space beyondthe seal strip which is occupied
by the door when in closed position, and which
space and the remaining vertical portion of the
channel are occupied by the door and its sup
2,120,827
porting frame during the manipulation of the
door. -As seen in Figs. 8 and 2,_the door 21 is
provided in its vertical edges with a passageway
28 which constitutes a track for the ‘door for
guiding same in its vertical movements. Received
latching or locking mechanism comprises a plate
44 having integral therewith a ?ange 45 through
which screws or the like extend for attaching
the plate to the cabinet ill at the upper end
thereof. The plate 44 is provided with a slot 46
?anked on each side by a cam face such as 41
in the said passageways is a frame comprising
and 48. At the ends of the cam" faces 41 and
48 the slot is-substantially parallel with the face
of the cabinet as shown at 43. Received in the
slot 46 is a ?nger 50 keyed or otherwise secured
10V a brace 31 which is integral therewith and forms ‘
to a short shaft 5| rotatably mounted in a bracket
in effect a U-shaped frame. It is to be under
stood, however, that this frame need not be 52 secured to the forward face of the door 21
integral but may have the upper ends of the near the upper end thereof. The outer end of
arms joined in some other manner. In order the shaft 5| carries a knob 53 whereby said shaft
may be rotated for actuating the ?nger 50 rela

‘
vided in its upper edge with a passage 32 which tive to the slot 46-43.
From the foregoing it is believed that the oper
is similar to the vertical edge passages 26. It will
be appreciated that if the-arms 29 and 30 are ation of the improved refrigerator door and its
joined in any other manner or are in fact left mounting will be understood. It should be noted,
‘however, that when the door has been shifted ‘
20 free, the passageway 32 is unnecessary. It
should also be noted that the foregoing specific to its uppermost position the knob 53 is rotated
to cause the ?nger 53 to enter the slot 46. Dur
description of the frame is given merely for~illus
trative purposes since the only essential parts of ing the movement of the ?nger 50 through this
the frame are the arms 23 and 30 to form a guide slot the cam face 46 causes the door 21 and the
frameiarms 29 and 33 to be oscillated in a clock- '

The arms 29 and 30 are respectively pivotally wise direction about the axis of the pivoted studs

It will be appreciated that the‘door 21 is of
considerable weight and to facilitate the raising
45 and lowering of said door there is provided a
counter-weight mechanism shown in the draw
ings as of the spring type but the invention is
not necessarily limited to this type of construc
tion as a simple ‘weight could be employed. As
50 shown in the drawings, particularly Fig.- 4, the
spring counter-weight comprises a housing 35 in
which is a coiled tape 36 having one end secured
to a rotatable spring cup 31. Within cup 31 is
a ?at coiled spring 38 having one end secured
55 to the inner surface of the cup 31‘ and the other
end secured to a shaft 39 about which the cup
31 rotates.' The free end of the tape 36 is se
cured at 40 to a stud 4| dependingfrom the lower
'edge of the door 21. The housing 35 is secured
60 in any desirable manner to the under surface of
the lowermost shelf l9 and it is believed that the
operation of the spring counter-balance is self
evident since the downward movement of the
door 21 will tend to coil the spring 38 which at
65 all times has sufllcient tension to prevent the
dropping thereof while the .upward movement of
the door is assisted by the uncoiling of the spring.

It should also be noted at this time that while
there has been shown but one counter-balancing
mechanism for the door two or more such mech

greater number of counter-balances being neces
