This invention relates to window screens such
as are adaptable for use in association with the
windows of the ordinary double ‘sash type, the
invention having reference, more in particular,
'to a flexible rollable type screen, that is, one which
wound on a spring-actuated drum or roller,
whereby to permit it to be raised and lowered
similarly to window and porch shades.
'In carrying out my inventive idea, I have had
tated 90° counterclockwise, this taken on the
plane of the line 3—3 of Figure ,1,
. Figure 4 is a fragmentary 'elevational view de
tailing ‘the clip-equipped longitudinal ‘edge por
tion of the screen.
Figure 5 is ‘a fragmentary horizontal ‘sectional
view similar to Figure 3.

‘window frames, the arrangement and designing
of parts being such that the installation may be
made either ‘facing the exterior or outside of the
dwelling, or facing the interior rooms.
More speci?cally, novelty is predicated upon the
adoption and. use of simple and expedient pairs
of vertical angle irons, these being provided with
opposed and spaced ?anges to thus provide track
like guides, the longitudinal edges of the rollable
?exible screen wire projecting between said guides
and having spring contact clips functioning as
shoes to guide and tautly maintain the screen as
it is rolled up or down, as the case may be.
More explicitly stated, the present invention
has to do with a screen which is adapted for use
in a frame and on a roller with special stabilizing
‘of the drawings, it may be pointed out that the
invention, briefly comprehended,‘ is- character
ized by pairs of coacting ?anged angle irons, these
mounted on anchoring plates on the window
frame structure. The longitudinal edges of the
raisable and lowerable ?exible screen project into
the guide tracks and-carry spring clips which slide
up and down in contact with the angle irons.
At the top of the structure is a casing or- housing
having a spring wound roller and the screen is
wound thereon.
Referring now to the drawings by distinguishing
reference numerals, it will be observed that the
structure is supported or mounted on the exterior
of the window frame, the latter denoted gener
ally by the numeral Il. As seen for example in
Figure 3, the attaching devices are in the form
of right angle plates l2 screwed or otherwise an

As before stated, and as diagrammatically in- ‘
dicated in Figure 6, the screen itself is made up of
relatively rigid parallel rods or stout wires 43'
connected together by highly ?exible intersect
ing vertical wires 44. This forms a sort of lattice

‘wooden slat porch shade or screen. That is to say,

of opposed parallel angle irons having flanges, the
inner faces of said ?anges being used to provide
runways, a screen edge projecting between the
flanges adjacent said runways, and. spring clips
attached to said screen edge and having rounded
portions workable in said runways. "
2. As a component part of an assemblage of the
class described and as a new article of manufac
ture, a screen adapted for use on a rollable screen
assembly of the class described comprising a
screen proper, and stabilizing devices attached to
opposite vertical edge portions of the screen, said
devices being arranged in ‘longitudinally spaced
relationship, each device ' comprising a pair of
