cabinets generally employed for refrigerating
purposes and has particular relation to the outer
wall, frame and supporting structure which such
5 cabinets ordinarily embrace, and to the method
`of constructing and assembling thereof.
tion.
This application is a division of my applica
tion, SerialNo. 692,882, filed October 9, 1933, for
“Cabinet Design”, now matured into Patent
1o 2,059,182 and reissued as Re. 20,610.
An object of the invention is to provide a
cabinet which shall be easy to assemble, at
tractive in appearance-and which can be manu- f
factured at a cost comparable with the cost of
15 cabinets of other designs now being produced.
Another object of the invention is to provide a
cabinet for refrigeration purposes, the outer sur
face of which is covered by a shell embracing
among other parts, a pair of end pieces or sections
20 which are provided with flanged edge portions
projecting inwardly toward the central portion of
the cabinet upon the front and upper walls
thereof.
Another object of the invention is to provide a
cabinet having an outer shell portion formed to
cover the surface thereof and embracing a pair
of end sections connected at the top by a top
panel covering only a portion of the upper sur
face of the cabinet with the remaining portion
39 of such surface being covered by inwardly pro
jecting portions of the panels employed for cover
N) Ul
ing the ends of the cabinet.
through the cabinet legs to within the building
in which the refrigerator is employed.
1 Another object of the invention is to provide a
novel method of constructing and assembling
cabinets of the type disclosed in this applica- 5
~
Another object of the invention is to provide` a
new type of base or supporting legs _for refrigera
35 tors which will provide for the latter a more
rigid support and at the same time will give to the
appearance of the entire structure a. more mas
sive and pleasing effect.
Another object of the invention is to provide
40 for a cabinet to be employed for refrigeration
- purposes, a support consisting of a pair of spaced
legs having a connecting portion adjacent the
upper extremities thereof which will not only
provide a stiñ‘ening element for the legs, but
45 will provide a substitute for a panel member
which ordinarily has been embodied in the cabinet
structure supported by the legs.
Another object of the invention is to provide a
resilient separating member to be disposed be
50 tween the lower surface of a cabinet employed
in refrigeration purposes and one or more of the
legs supporting the cabinet for the purpose of
deadening the sound vibrations generated in the
refrigerating mechanism employed in the cabinet
i5 and which> might otherwise bel transmitted
'
'I‘he embodiment of the invention disclosed> for
the purpose of illustration comprises generally a
pair of end sections which, in the present in
stance, are formed from a single sheet of metal 1o
by suitably constructed dies and each of which
is provided with inwardly ñanged edge portions
at the upper and the front and rear edge por
tions thereof. 'I‘he iianges at the front of the
end sections aforesaid, project inwardly for the l5
purpose of covering the front surface of the
cabinet beyond the door openings formed therein
and at the upper extremities thereof, the flanged
portions project inwardly to provide preferably
a flush joint with an upper section, the forward `20
edge of which extends downwardly toward the
aforesaid‘door openings and in such region pro
vides for closing the space between> the inwardly
flanged front and upper portions of the end
panels.
'
25
The refrigerator, if desired, may be provided
with a frame of any suitable character, an in
sulated inner compartment for storing provisions,
and a machine compartment for housing the re
frigerating mechanism with which such cabinets 30
ordinarily are provided. Any number of doors
maybe employed for obtaining access to the
interior of the refrigerated compartment and to
the machine compartment employed therewith.
The legs, in the present instance, are formed 35
of stamped sheet metal-and extend a considerable
distance along the two sides of the cabinet ad
jacent each corner. The legs, however, may be ‘
formed of any suitable material and may be of `
any desired design.
40
At the front "of the cabinet there is employed
.an elongated reinforcing panel which extends
downwardly just below the front of the cabinet
and fills the space between the two front legs.
Rubber gaskets are employed between the ñanged 45
upper portion _of each of the legs and the lower
parts of the cabinet adjacent thereto and be
tween the front reinforcing panel and,V the legs
and the lower part of the cabinet adjacent such
panel.
50
It will be observed that a plurality of doors are
employed on the front of the cabinet for the
refrigerating and machine compartment and that
such doors are so closely disposed together as to
provide a substantially continuous' panel over the 55

the front of the cabinet, and a pair of sections 20
or legs 29 supporting the rear of the cabinet.
In orde` to provide a supporting structure for
the several walls of the cabinet I0, there is em
ployed internally thereof, a frame 3l, the front
portion of which is formed around the front of the 25
cabinet to provide a door frame 32 through which

rounded edge indicated at 3l, so that the exterior
covering of the cabinet can be formed with the
desired contour in such- regions. At the upper
corners of the cabinet there are also a pair of
rearwardly extended frame members indicated at

v
The rear of the cabinet is supported by a rear
frame indicated at 38, consisting of a pair of ver
tical side members 31 and cross members ar
ranged at points between the two for giving the
frame the proper strength and rigidity. Various \
other cross members are provided between the
front and rear frames 3l and 38 for the purpose ,
of rigidly maintaining the two trames in proper
relation. ’Inside the reirigerating compartment
a rear wall i6. Inside the two walls ii and i2
il and within the various frame members located
and between the lower wall lil and the upper ` thereabout and within the walls of the cabinet,

there is disposed an inner shell or tank member
erating compartment il, and beneath the wall id
55 and between the walls ii and i2, there is a ma
chine compartment iß in which the condensing
unit (not shown) for the refrigerating` mecha
nism is shown. The walls of the refrigeratixîg
_compartment Il are provided with thick insulat
60 ing slabs of any suitable character, and the walls
of the machine compartment I8 are provided, if
desired, with relatively thin sound-absorbing slabs
for damping out the vibrations and noises orig
inating in the refrlgerating mechanism located
therein.
_
'
The refrlgerating compartment il' may have
one or more doors such as those indicated at 2|
and 22. When two doors are employed, as in the
present instance, there generally is. provided a
70 center post or pilaster, such as that indicated at
2i, i'or enclosing the space between the doors
and providing a solid obstruction against which
the inner edges of the doors are supported.` These
doors normally are heat insulated, as are the
remainder of the walls of the reirigeïatiûg 00m
W
39, and the front edges of which are provided 55
with iianges indicated at 4i, which are secured
to the inside edge of the front frame 3i around
the door opening i’ormedl therein.
Outside oi' the tank 39 and between the frame
members thereabout, there are employedy slabs of 60
heat insulating material indicated at 42, which
tend to materially reduce the ilow of heat be
tween the interior and the exterior of the cabinet.
A top sub-panel 82, of wood or any other suit
able reinforcing material, is disposed above the 65
insulating material 42 on the top of the container
39 and is secured between the front, side, and rear
top frame members and supported thereby in such
a manner that the upper surface is flush with that
or said frame members. Sub-panel 62 is cut 70
away at the side edges thereof to provide a groove
extending across the top of the frame and which
is adapted to receive ñanges provided on the ton
and side panels of the cabinet.
v
For covering the exterior of the cabinet, there 76

'I'h'è inner edges of the `
front flanges 49 are formed with securing flanges
53 which extend inwardly of the opening to the
refrigerating compartment i1 and are secured
20 to the inner edges of the door frame 3l directly
opposite the flanges 4I formed on the inner shell
or `tank 39.
All of the ñanges, such as are in
dicated at «Hand 53, are covered by trim strips
indicated at 54, which 4are secured to the inner
25 surface of the door frame 32 by screws 56.
y
The top flanges 5i and also the front edge of
the front flanges 49 down to the door opening
in the cabinet, are provided with inwardly pro
jecting securing flanges indicated at 51, which
30 project into grooves formed in the insulating ma
terial and the frame of the cabinet in regionsad
jacent thereto.
The side panels 44 and 46 are put on the walls
of the cabinet by first inserting the securing
flanges 53 inside the door opening and holding the
remainder thereof away from the cabinet and
upwardly beyond the normal position thereof, to
such an extent that the upper securing flanges 51
are free to move above the upper surface of the
cabinet. From this position, the sections are
pivoted inwardly upon the ñanges 53 until the
sides of the tcabinet are engaged by the inward
surfaces thereof, and the flange 52 is in position
upon the rear cabinet wall. When the panels are
in this position, the ñanges 51 are immediately
above the grooves formed in the top of the
cabinet and may thereafter be inserted therein
simply by allowing the panels to slide downwardly
uppervpanel 41 is placed in position somewhat
like the side panels 44 and 46, by inserting the
securing flange 64 beneath the lower edge of the
upper member of the frame 32 and then moving
the rear of the panel downwardly until the rear 20
flange 66 is-in position beside the flanges 51. The
gasket 69 is placed in position upon the flanges
ilbefore the top panel is moved into position,
and consequently the gaskets slide downwardly
into position betweenethe flanges 51 and 61 as the 25
top is moved into place.
It will be observed that the cabinet has the
appearance, from the front sides and top there
of, of being constructed principally of three pieces
consisting of the side panels 44, 46 and the top 30
panel 41 and a plurality of doors covering sub
stantially the entire front of the cabinet except
for the space thereabout formed by the front
flange portion ofthe top and two sides aforemen
tioned. The top panel 41 is so formed and moved
into position as to form substantially flush joints
with the upper extremities of the two end panels
44 and 46, thus giving the cabinet a pleasing ap
pearance characterized by a classic simplicity
of design.
v
"
'I'he back of the cabinet can be covered by an
40
ordinary flat covering such as that indicated at
`46, and the outer edges of which are secured in
any suitable manner inside the flanges 52 of the
side panels 44 and 46 and the flange 6E of the
top panel 41.
.

In the present instance, the doors 2l and 22
of the refrigerating compartment l1 and the
door 24 of the machine compartment I8 are
upon the cabinet side walls. In order to prevent
positioned in such manner as to extend out
the panels from rattling or from becoming dis

upper edges of the panels to secure them in posi
doors may be put on in any other desired man

ner without materially changing the appear
The top panel 41, which, in the present in
55
stance, is substantially of the same cross sec‘
tional contour as are the two side panels 44 and
46, also has a front flange -63 projecting down
wardly across the front of the cabinet and into the
door opening space therein and the lower end
of which is provided with an inwardly projecting
securing flange 64, which is adapted to be se
cured around the lower surface of the upper sec
tion of the door frame 32. The rear edge of the
top panel 41 also is turned downwardly, as- is in
dicated at 66, for the purpose of engaging a por
tion of the back of the cabinet, as do the rear
flanges 52 on the side panels 44 and 46. The op
posite edges of the upper panel 41 are turned
downwardly and inwardly across the top and
front and rear sections thereofl respectively and
as is indicated at 61, to provide securing flanges
ance of the entire structure.

«
The base 21, consisting of the front section 28
and the two rear sections 29, normally is se
cured upon inwardly projecting flanges ‘16 formed
along the upper edges of the parts, and between 60
theseiianges and the cabinet there are disposed
a plurality of beaded rubber gasket sections indi
cated generally at 11. The front section 28 of
the base consists of a pair of massive legs 19 and `
8l, and between which there is connected, with
suitable rubber gaskets 82 and 83 at opposite 65.
ends thereof, a spacing panel or skirt B4. Ad
jacent the central portion of the panel 84 there
is formed, outwardly from the rest of thesur
face thereof, a projection 86, the surface of which 70
is set atv an'angle to the vertical _surface of the
cabinet and base adjacent thereto, to provide a
region where the’ name of the productv may be
61 which are adapted to extend downwardly into> easily seen by anyone standing in front of the
the grooves formed in the top, front and rear of
cabinet and looking' downwardly.
The spacing ‘

_2,117,082
panel 84 is secured to the adjacent edges of the
legs 19 and 8l by bolts 81 which are adapted to
compress the gaskets 82 and 83 between flanges
89 and si formed at the adjacent edges of the
aforesaid parts. It is preferable to provide prac
tically all of the edges of the two legs 29, the
legs 19 and 8|, and the spacing panel 84, with
rearwardly extending iianges on both the upper
and lower extremities thereof and on interme
-10 diate edges therebetween, in order to provide
thek base structure with adequate structural
strength and in addition, to give the entire base
yopening with said upper covering flange elevated
above said top wall to permit free movement of
said top securing flange across said top wall, then
moving said panel angularly until the inner sur
face thereof engages the outer surface of said
end wall, and then sliding said panel downward
ly until said top securing ilange is confined within
a grooved portion of the surface ioi' said upper
wall.

2. 'I'he method Vof constructing a cabinet which
consists in forming a substantially rigid frame
work having a top wall, an end wall, a front
wall provided with a door opening therein, and
a three sided corner forming at the juncturel of
said walls, forming grooves in said top and front 15
walls substantially in alignment with one of the
edges of said door opening, forming an end panel
projecting portion indicated ,at 93, in the region member to provide a continuous iîange extend
thereof just below the lower edge of the machine. ing laterally thereof for covering a portion of
the top and front walls and the three sided corner :20

carries out the general `paneled effect formed by in addition to the end wall and seeming ñanges
the doors in the »front surface of the cabinet and extending inwardly from the extremities of said
prevents the doors from having the appearance covering flanges for engagement with said
grooves and door opening, then inserting said
of overhanging the base.
25
The frame structure, insulation, inner and front seeming ñange in said door opening with
said
upper
covering

elevated
above
said
outer coverings, the doors and the base, all may
be manufactured as separate units and assembled top wall to permit free movement of said top
in production in such manner that any part may securing frame across said top wall, then moving
be taken off and replaced, in the event it should said panel member angularly until the inner
surface thereof engages the outer surface of V30

doors on the front of the cabinet project out
15 wardly thereof, as do the doors in the cabinet
i0, disclosed herein, it may be desirable to pro- '
vide the front face section with a forwardly
desired.
’
It is to be understood that the invention is not
lìimited to the specific features of the structure
disclosed, but is to be considered broadly as is
represented by the scope of the appended claims.
