Improvements in and applicable to Window Blinds and Drop
Screens.
THOMAS HENRY CHADWICK of 35, Edward Street, Oldham, County of
Lancaster, Secretary to a company, and JOHN GEORGE CHADWICK of 2 Chamber
Road Oldham, County of Lancaster, of no occupation do hereby declare the nature
of this invention to be as follows:-
Our said invention relates to means or apparatus for a more suitable mode of
winding-up window blinds or drop screens made of cotton cloth or other fabric.
To do this we employ two or more cords fixed at suitable distances apart from
each other and passing over small pulleys or other suspenders in the upper bar as
in the ordinary Venetian wooden blinds. The cords then pass through apertures
in, or rings or loops attached to, the fabric at regular distances, alternately inside
and outside, or from front to back or vice-versa or down both sides till the bottom
bar is reached to which the cords are connected. The action of winding-up the
blind or screen pleats the cloth or fabric in regular flat layers of about 3 inches
broad or other suitable breadth.
When the blind or screen is drawn up to the top the two bars, top and bottom,
come together except that the pleated fabric lies between neatly and regularly
folded and secure from harm and scarcely obstructing any light.
When the blind or screen is let down the weight of the bottom bar takes down
the fabric quite noiselessly. The usual rattle of rack roller or wooden sheaths is
avoided. The breakage of cords is minimised as the weight of the blind is very
small compared to other descriptions.

COMPLETE SPECIFICATION.
Improvements in and applicable to Window Blinds and Drop
Screens.
We, THOMAS HENRY CHADWICK 35, Edward Street, Oldham in the County
of Lancaster, Secretary to a company and JOHN GEORGE CHADWICK,
2 Chamber Road, Oldham also in the said County of Lancaster, of no occupation,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Our invention consists in a simple and neat arrangement of raising and lowering
window blinds or drop screens suitable for domestic houses, mills, manufactories,
workshops, theatres, or other places of amusement; railway or other carriages or
conveyance windows.
The blinds or screens may be made of any kind of light fabric of cotton, woollen,
silk or other material. The principal part of our invention is the mode or manner
of raising and lowering the blind or fabric. To do this we employ two, three or
more cords placed at suitable distances apart from each other according to the
width of the window or other opening-and these cords pass over small pulleys,
or other suspenders fixed in a wooden or metal bar in the upper part of the window
or opening.
The cords are interlaced to the fabric through apertures in the cloth or rings

page_text: attached thereto and then secured to the bottom bar as in the ordinary Venetian
blind.
The action of winding up the blind or screen pleats or folds the fabric in regular
flat layers of about 3 inches or other suitable breadth. When the blind or screen
is drawn up to the top the two bars-top and bottom-come close together except
the pleated fabric lies between neatly and regularly folded and secure from harm
and scarcely obstructing any light.
When the blind or screen is let down the weight of the bottom bar draws down
the fabric quite noiselessly; the usual rattle of rack-roller or wooden lath is done
away with. The breakage of cords is minimised. The blinds are light and easy of
management, and the whole complete forms a neat substitute of other kinds of
blinds or screens.

claim is :-
1-The winding arrangement combined with the automatic regular plaiting of
the cloth or fabric by the interlacing of such fabric with a suitable number of
cords.
