PROVISIONAL SPECIFICATION.
Improvements in Window Blinds, and in the Manufacture of
the same.
I, GEORGE WILSON of 87 Newton Road Sparkbrook, Birmingham, in the
County of Warwick Window Blind Maker, do hereby declare the nature of my
said invention to be as follows:-
My invention has for its object improvements in window blinds and in the
manufacture of the same, which are not liable to stains and deterioration like
ordinary blinds and they can be easily sponged and cleaned without removal from
the windows.
In the manufacture of my new blinds I use "holland" or other textile material
such for instance as the material known as "union" but I prefer the "holland."
In the course of preparing the material for use I first fill in the interstices of the
material by a mixture of size with vegetable black or other similar substance and
this applied while the material is in a tight condition with a sponge after which it
is dried. In the second place I apply one or more coats of oil paint to each side,
of any desired color and when dry both faces are well sponged down with a strong
solution of alum water or its equivalent. When this is dry the material is ready
to be made up into blinds.
Dated this 28th of July 1896.

COMPLETE SPECIFICATION.
Improvements in Window Blinds, and in the Manufacture of
the same.
I GEORGE WILSON of 87 Newton Road Sparkbrook, Birmingham in the
County of Warwick Window Blind Maker, do hereby declare the nature of my
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention has for its object improvements in window bliuds and in the
manufacture of the same, which are not liable to stains and deterioration like
ordinary blinds and they can be easily sponged and cleaned without removal from
the windows.
In the manufacture of my new blinds I use "holland" or other textile material
such for instance as the material known as "union" but I prefer the "holland."
In the course of preparing the material for use I first fill in the interstices of the
material by a mixture of size with vegetable black or other similar substance and
this applied while the material is in a tight condition with a sponge after which
it is dried. In the second place I apply one or more coats of oil paint to each side.
of any desired color and when dry both faces are well sponged down with a strong

page_text: solution of alum water or its equivalent. When this is dry the material is ready
to be made up into blinds.
If the blinds or other articles are required transparent or semi transparent I may
treat the material without the black mixture, or when they are required any other
color than black, I mix such color instead of the black, but otherwise the treatment
is the same.
Such blinds or screens form a very suitable ground for lettering or for various,
devices or illustrations and may be used whether the blinds are made opaque or
semi opaque. The opaque material is specially suitable for photographers dark
rooms and for screens and for a variety of purposes as well as the colored or semi-
opaque ones..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
CLAIM.
The improvements in window blinds and in the manufacture of the same which
is also applicable to other purposes consisting of textile material treated with the
materials above stated in their manufacture substantially as herein set forth.
