My invention is an improved refrigerator par
ticularly adapted for use as ^a display counter,
and designed to provide a more efficient means
for minimizing the ingress of warm or moisture
iïg' laden air to the food“ compartment, through the
mountings of the transparent panelsby which the
contents of the refrigerated chamber are dis
of the planes thereof. ‘
On outer rim or frame 33 is fitted against
the outer panelframe 32 in a groove in the walls
'
"
permeable substance such as wax, paint or sheet
material. In one form, all of the panels and
frames are adaptedfor shipment as an assembled
4, 6 and 3 I. Screws-34, 35 and `36 hold the panels
in position and clamp the faces of the frames
together. The screws 34 secure the frame 33 to
the stringers 5 and 6 and to the upright beams 3 I.
The screws 35 (shown in Figs. 1 and 2), each
extend through the outer rim 33 and through each
of the panel frames 32 into the stringers 5 and 6,
and the screws 36 (shown in Fig. 3) areprefer
ably shorter and connect and draw together the
faces of each adjacent pair of frames 32 and
members 33 and 29.
When the screws are driven home, the surfaces

of the adjacent frames and casing members are
drawn together tightly to prevent seepage of air
into the refrigerating chamber; The joints be
tween these surfaces preferably have between
them compressible gaskets 31, as of rubber or 30
paper, and packings or sealing elements 38, as
of putty, which provides a plastic seal for the
glass panels in the frame grooves. Coatings 39,
In the drawing, Fig. 1 is a transverse sectional
view through a refrigerator display case embody
ing my invention; Fig. 2 is an enlarged trans
verse sectional view showing .the construction
of the top of the front of the case and the mount
ing of the panel rims; Fig. 2a is a view, similar to
Fig. 2, of a modified form of the structure there
of; and Fig. 3 is an enlarged transverse sectional
View through the right hand side of the case
viewed from the front taken substantially on
the line 3_3 of Fig. 1, and showing the mounting
of the sides of the panel frame.
As illustrated in the drawing, my invention is
embodied in a counter display case comprising
an insulated wall I forming an inclined bottom 2,
an insulated rear wall 3, a front wall 4 having
a bottom beam or stringer 5, and a top beam or
Stringer 6. The rear wall 3 supports an in
sulated shelf l, which is connected with a sup
porting beam 8. A top beam 9 coacts with the
beam t to support the insulated top member I Il.
The front wall 4 supports a plurality of spaced
on? thel edge and adjacent side surfaces of the
panel frames 32 to prevent breathing of moist air
into the space between the panels, ordinarily
caused by the difference oftemperature ‘between
the interior and exterior of the case.
Trim bands or moulding 40 may be secured to
the frames 32 between the panels 28 by tacking,
(as shown in Figs. 2 and 3) , to enclose the gaskets
and packing elements. These bands have
beveled edges and cooperate with the frames and
the panels to provide spaces into which the
gaskets and packing may expand or be extruded
unseen, thereby providing a finished appearance
and simplifying the construction and installation
of the elements.
As illustrated in Fig. 2m, each of the panels 28
is provided with a frame 32 which is secured to
the others and the outer frame 33 is secured
thereto by the screws 36, whereby all of these
members may constitute an assembled unit, sep
arable from the case, and may be shipped and
or self-sustained unit.
Access to the interior of the refrigerated cham
ber is preferably provided by means of composi
tion
doors.
