6 Claim. (Cl. ltd-till)
This invention relates to improved means for numeral ll. This inside storm curtain comprises
insulating wall openings in the nature of windows a sheet of transparent material which is gen~
and pertains particularly to an improved curtain erally indicated by the numeral ii and which con
for forming such insulation means.

sists of the transparent cellulosic substance, of.
The present invention has for its primary ob
which one form is marketed under the name 5
ject to provide an improved curtain structure of “Cellophane.” This sheet of transparent mate
transparent material, and means for securing the rial is formed of the proper width and length
same upon the inner side of a window, whereby ' to completely cover the window frame, and one
a dead air space will be set up against the inner
end edge of the same is secured to a roller t
side of the window glass so as to provide an e?ec
which has the same construction as the roller 10
tive insulation means for preventing the loss of commonly employed for carrying a shade, except
heat through the window.
for the fact that the usual pivoted dogs of the
llnother object of. the invention is to provide
a transparent curtain ‘for the purpose above set
16 forth, in which a novel means is employed for
securing the edges of the curtain to the window
frame so as to effectively prevent the circulation
of air between the curtain and window.
A still further object of the invention is to pro
20 vide an improved curtain formed of transparent
cellulosic material in the nature of cellophane
with novel means for securing the curtain while
in use to prevent longitudinal and transverse
wrinkling of. the same.
The invention will be best understood from a
consideration of the following detailed descrip
tion taken in connection with the accompanying
drawing forming part of this speci?cation, with
the understanding, however, that the invention is
not con?ned to any strict conformity with the
showing of the drawing but may be changed or
modi?ed so long as‘such changes or modi?cations
mark no material departure from the salient
features of the invention as expressed in the ap
pended claims.
In the drawing:
Figure 1 is a view in elevation of a window
showing the device embodying the present iii
vention applied thereto.
Fig. 2 is a view upon an enlarged scale of spring
holding meansjor the edge of the curtain.
Fig. 3 is a sectional view taken on the line il-t
of Fig. 2.
Fig. 4 is a plan view of a modi?ed form of our
tain holding means.

Fig. 5 is a sectional view on the line 5-5 of
.Fig. 4.
‘
Referring now more particularly to the draw
ing, the numeral I generally designates the frame
of a window in which are slidably mounted the
usual glass carrying sashes 2.
'
The curtain structure embodying the present
invention is designed to be mounted upon the
top cross bar 3 of the frame above the usual
shade roller which is generally indicated by the
shade roller are removed so that the storm cur
tain roller can he turned freely, and for facili
tating the rolling up of the transparent curtain 15
material thereon it has in the recess "1! which is
formed in one end thereof, the usual spring ill
which is coupled with the rotatable trunnion t.
At the other end of the roller a ?xed trunnion
it is located, and these trunnions t and it are
mounted in the usual shade roll supporting
brackets ll.
The transparent curtain carrying roller is
mounted, as previously stated, upon the window
frame above the usual shade roller ll, and the cur
tain t is drawn down between the frame and
the shade roller, as illustrated. The end of the
curtain t opposite from the roller it has secured
thereaeross a bar of iron it, or any other suitable
heavy material and the ends of this bar extend
beyond the side edges of the curtain t and are
provided with the apertures l3 to receive the re
taining pins it which are secured in the side por
tions it of. the window frame at the lower ends
thereof. By the provision of the bar it at the
lower edge of the transparent curtain and the
pins it for connection with this bar when the
curtain is drawn down, the curtain is securely
held against the tension of the wound spring t
so that it will be prevented from returning to its
rolled-up position and also it will be prevented
20
25
30

40
from developing transverse wrinkles which might
otherwise form in the material of which it is
formed.
In order to maintain the ‘side edges of the 45
curtain 5 close against the side portions I5 of the
window frame, there is provided a series of
springs for attachment along the length of the
face of each side portion of the frame. Each
of these springs comprises a loop of spring wire 50
it which at one end has an eye I‘! through which
a securing screw it is passed. This screw not
only ?xes the inner end of each spring l6 relative
to the adjacent edge of the transparent curtain,
but also holds the spring in ?rmly against the 55
2
2,126,328
face of the frame so that when the free end of
the spring is engaged with the edge of the cur
tain it will force this edge against the frame and
thus set up a relatively tight joint between the
frame and curtain.
The free end of each spring wire I6 is pro
vided with a hook I! and formed along each ion
gitudinal edge of the curtain 5 is a series of aper
tures 20 each of which is encircled by a suitable
10 annular reinforcement 2| which prevents the
hook I! of the spring from tearing the curtain
material. The number of apertures 20 along each
side of the curtain equals the number of springs
attached to the adjacent side of the window
er positions over the curtain for engagement in
their respective apertures.
As will be readily apparent from the foregoing,
a novel feature of the present invention resides
in the fact that a storm curtain can be easily 5
and quickly drawn into position across a window
when necessary and while it is in use no light
will be prevented from entering through the win
dow. The device may also be economically con
structed so that it maybe sold at a reasonable 10
price and thus be made available where more
expensive storm curtain structures could not be
used.

‘In this form there is provided a disc 22 of heavy

45 face so as to facilitate its being secured by this
medium to the’ side portion I5 of the window
frame in place of the screw it used for attaching
the spring I6. This disc 2| carries a central
post 22 to which is attached one end of the spring
50 wire 23, the outer end of which is provided with
a hook 24 for use in the same manner described
in connection with the spring it. By providing
these gummed or adhesive carrying discs the
springs may be attached to the faces of the side
