AN IMPROVED TEXTILE FABRIC
Year: 1862

page_text: LETTERS PATENT to John William Caley and Frederick Goodman Caley,
of the firm of Caley Brothers, of New Windsor, in the County of Berks,
Silk Mercers, for the Invention of "AN IMPROVED TEXTILE FABRIC."
Sealed the 29th August 1862, and dated the 29th April 1862.
PROVISIONAL SPECIFICATION left by the said John William Caley and
Frederick Goodman Caley at the Office of the Commissioners of Patents,
with their Petition, on the 29th April 1862.
We, JOHN WILLIAM CALEY and FREDERIC GOODMAN CALEY, of the Firm of
Caley Brothers, of New Windsor, in the County of Berks, Silk Mercers,
do hereby declare the nature of the said Invention for an "IMPROVED TEXTILE
FABRIC," to be as follows:-
The material forming the subject of our Invention is especially intended for
window roller blinds, but may also be applied to many other uses. We propose
weaving the fabric with a semi-transparent pattern, that is to say, with designs
of any form or shape having an open mesh (very similar to lace or net) through
which the light will penetrate with greater facility than through the plain or
close part of the fabric. Cotton window roller blinds woven with this semi-
transparent or openwork pattern will have a very rich appearance and diffuse
much more but still a softened light winthin the apartment than the ordinary
patternless linen or union blind.

by the said John William Caley and Frederick Goodman Caley in the
Great Seal Patent Office on the 27th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
WILLIAM CALEY and FREDERICK GOODMAN CALEY, of the Firm of Caley
Brothers, of New Windsor, in the County of Berks, Silk Mercers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said John William Caley and Frederick Goodman Caley, Her special licence
that we, the said John William Caley and Frederick Goodman Caley, our
executors, administrators, and assigns, or such others as we, the said
John William Caley and Frederick Goodman Caley, our executors, ad-
ministrators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed
should and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "AN IMPROVED TEXTILE FABRIC," upon the condition (amongst
others) that we, the said John William Caley and Frederick Goodman Caley,
our executors or administrators, by an instrument in writing under our, or
one of our, their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said John William Caley and Frederick
Goodman Caley, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the
Sheet of Drawing hereunto annexed, and forming, part of this our Specifica-
tion, and to the letters of reference placed thercon.
It
The textile fabric forming the subject of our Invention, although more
especially intended for window roller blinds; may be applied to other, uses.
is of cotton and manufactured with a semi-transparent pattern, that is to say,
with figures or designs in gauze or openwork very similar to lace or net.
Through this gauze or openwork light penetrates more freely than through

page_text: the ground or close part of the fabric, which, when used for a blind, has a
very rich appearance, and while softening the light diffuses more within the
apartment than the ordinary even or patternless blind. Our improved fabric
is produced by the gauze or openwork part, having the threads in the warp
twisted together according to the requirement of the pattern to be produced,
and the plain or ground part by the threads in the warp rising and falling two
threads up and one thread down alternately, as shewn in the accompanying
Drawing, on which a indicates the back healds, 6 the gauze healds, c the doup
healds, d the reed, e the treadles of the loom, f the gauze or openwork pattern
of the fabric, and g ground part of same. The Drawing represents a small
pattern; to weave larger figured patterns we substitute a jacquard machine
for the
gauze healds.
Having now described the nature of our said Invention and means by which
we carry it into practical effect, we would have it distinctly understood that we
do not confine ourselves to any particular pattern or design, as such may be
varied at pleasure, nor to the precise details herein set forth, but that we claim
the exclusive use of the improved textile fabric woven with semi-transparent
gauze or openwork pattern, essentially as herein-before described and illustrated
by the annexed Drawing.
In witness whereof, we, the said John William Caley and Frederick
Goodman Caley, have hereunto set our hands and seals, this Twenty-
fifth day of October, in the year of our Lord One thousand eight
hundred and sixty-two.
JOHN WILLIAM CALEY.
