This invention is a division of my application
Serial No. 324,395 ?led March '16, 1940gwhich
has eventuated into Patent 2,349,225‘ 'of‘May 16,
1944, and relates to a rollable sheet for covering
window openings.
Speci?cally my invention contemplates a roll-v
83. This rollable window screen has a binding
6i} secured thereto in the manner described in my
patent for Screen frames, Patent No. 2,297,729,
issued October 6, 1942. '
This binding at may have openings 82'therein,

in which grommets of the type 66 may be inserted
in order to aid in securing or which may be used
for securing purposes in the condition in which

Many other objects and uses of this inven

out in the following description and drawing in

one form of edge binding of the rollable window 40
Figure 2 is a fragmentary perspective showing
the use of the rollable window screen of my
invention in connection with a sliding window
Figure 3 is a fragmentary perspective showing
the utilization of the rollable window screen of
my invention in connection with a rollable sheet;
Figure 4 is a fragmentary view of a portion of
the rollable sheet of Figure 3.
Referring to Figure 1, I have shown a por
tion of a rollable window screen comprising the
lateral stability of the binding withoutinteré
fering with the reliability of the screen. Since
the ‘metal strip 8| by reason of its cross-section
will not yield when tensioning forces are pro?
duced ‘thereon in the direction indicated by the
arrows 83, unsightly gaps or the possibility‘of. ’
escape of the screen from its guides are obviated.
In Figure 3 I have shown the application of
my rollable window screen 20 to a window which
is also to have a rollable transparent or opaque
sheet material which will come into the opening
as the screen is withdrawn therefrom or which
will be withdrawn from the window opening as
the screen is drawn thereinto.
The rollable window screen is at Iiiél mounted
in the top “II of the window and the edge I06
thereof is supported in suitable guides in the
manner hereinbefore described. The rollable
