2 Claims.
This invention relates to window sections.
This invention has utility especially in con
nection with vitreous or glass panes having fused
framing therefor which may be assembled into
5 sealed air chamber panels adapted for tempera.

Referring to the drawing:
Fig. 1 is a side view, with parts broken away,
of a panel unit;
10 ' Fig. 2 is a section on the line II-III, Fig. 1;
. Fig. 3 is a perspective view of a frame with
partial pane therein;
Fig» 4 is a section through a frame assembly
having departure inthe oñ'set _between the flanges
15 from that in Fig. 2;
Fig.. 5 is a fragmentary View of panel assembly
with supplemental gasket sealing in addition to
the bonding therebetween; .
Fig. 6 yis a section on the line ITI-VI, Fig. 5;
20 and
Fig. 7 is a section at the frame involving a
plurality of air chambers for the unit.
.These units for the frames desirably are oil
mounted in a movable section. 'I‘he diaphonous
element 4 may be selected either for color or
for transmitting lselected rays as to actinic effect.
Furthermore, the character thereof, whether
sheet orv plate, and whether thin or heavy, may 5
be adapted'for that of the ultimate installation.
The compressible packing 8 desirably has thereon
shellac I0 as a binding agent against shifting
relatively to one of the panes 4. 'I'his binding
agent holds the packing 8 against shifting into 10
air chamber II between the panes of the unit.
e In lieu of the abruptofrset 3, there may be
tapered onset I2 (Fig. 4). 'I'his is a cushioning
form of construction avoiding strains from ex;
pansion and contraction, although experience 15
with the solder as the bonding agent between
the metal and pane has, with thin sheet metal
framing, been eil'ective for such holding as to
maintain sealing of the air chamber II under
wide temperature changes.

The outer ñange I of these panel units as away

What is claimed and itis desired to secure by
United States Letters Patent is:
1. A double glazed panel comprisingl two simi

soldered to said frame, resilient spacing means
between said panes, a separate continuousgasket 45
