Improvements in Window Blinds.
I, EDWARD FRANCIS HUTCHINS, Architect of No. 9 Dumont Road, Stoke
Newington, London, N. do hereby declare the nature of this invention to be as
follows:-
I form or construct a window blind of linen or other flexible material in the
usual way, by securing one edge thereof to a roller (marked A on the
accompanying drawing) which can be rotated by an endless band, in the usual, or
any other convenient manner. This blind I make double, as it descends, by
securing its opposite edge to a fixed bar or slat (marked B on drawing) in such
manner, that as the two folds will descend with unequal speeds, so any given
horizontal part of one fold can be brought opposite to any given horizontal part of
the other fold with the effect that, by making the blind in alternate stripes or
other patterns, of dark and light colours, light can be either admitted or excluded,
after (in some degree) the manner of a Venetian blind. For when the dark parts
in the two folds are opposite each other the light will enter through the light parts,
and when the dark part in one fold is opposite the light part in the other fold the
light will be excluded; and as the dark and light parts approach each other, so
will the light be more or less, at the will of the user.
The bar or roller marked D. on drawing keeps the blind taut, whilst the guides
marked C, keep the folds together at the bottom.
I do not, however, bind myself to the precise mechanical means which are shown
on the drawings, but apply for Provisional Protection for the principal above
described of admitting or excluding light by means of a double-fold blind with
bands of dark and light alternate colours or patterns, whether disposed (as by
preference) horizontally or in any other way or manner or in any other pattern or
design.

COMPLETE SPECIFICATION.
Improvements in Window Blinds.
I, EDWARD FRANCIS HUTCHINS, Architect, of No. 9 Dumont Road, Stoke
Newington, London, N. do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates more particularly to window blinds made of linen, or
other material or fabric, of a striped and perforated, or striped or perforated, or
other suitable pattern, whereon the pattern is arranged horizontally and alternately,
in dark and light stripes or spaces, and has for its object to render such blinds as
effective for admitting and excluding the light and air as Venetian blinds, at the
same time that they are much cheaper, ueater in appearance, and more convenient
for use.
And in order that my said invention may be better understood, and readily
carried into effect, I will now proceed with the aid of the accompanying drawings
to describe the same.
To carry out my invention I make the blind of linen, or other material or
fabric, whereon dark and light stripes and perforations, or stripes or perforations,
or other suitable pattern or patterns, are arranged horizontally, and alternately.
