ñange on its inner side. The strip 21 has an
additional function which will be described later.
The top surface of the upper bar 25a of the storm
screen edge in suitably formed channels at each
side of the window frame. The channels of each ‘
pair (one pair for each sash) are identical ex
cept that one is right hand and the other left
hand; hence only one of the four channels re
sash lies against the lower wall 2l so as to es
quires description.
As shown by Figs. 3 and 8, ‘each guide channel
comprises a pair of cooperating parallel guide
tablish, in cooperation with the sealing strip 26,
a relatively tight joint.
.
IThe storm sash25 provided as usual with pro
tective panes 28, partially shown, is ordinarily
supplied several inches longer than it needs to
be in order to ñt the 4windows for which built.
An extra wide margin is usually provided at the
elements 58 and 5I preferably made as separate
' Z-bar shaped strips of sheet metal having ñange
portions 52 and 53 which lie against each other
-and one of which, as shown, is extended for
wardly at right angles to the plane of the guide
bottom and for use with the present arrange
ment it is usually only necessaryto Icut off as
l 5 channel to form a flange 54 for attachment to
" much from the bottom of the stormV sash as will
the adjacent window frame. The flange 54, as
shown, is attached as by screws 55 to the adja
cent vertical window casing rib 14a which co
operates with the upper rib I4 of the casing in
forming Ythe outer guide for the upper sash I0.
Thus a channel trackway is formed at each side
of the upper sash and extending’substantially
from the top of the frame 'downwardly nearly to
the lower limit of the upper sash. The channels
are made long enough so that the T-head'guides
48 will not be moved out of theV channels when
the upper sash is fully lowered and carries the
screen with it to span the opening above the
make the upper and lower bars 25a -and 2519 of -
the storm sash approximately of the same height.
In some cases, of course, small portions of the
top bar 25a may have to be cut off in order to
accommodate the casing I5. '
'
The storm sash is secured to the window by
suitable means such as hinges shown at 29, Fig. 1,
andan appropriate catch-- device or hook (not
shown) at the side of the window opposite the
hinges.

screen wire or plastic strands 30 is secured at one
