AN IMPROVED MANU- FACTURE OF CERTAIN TEXTILE FABRICS
Year: 1872

page_text: LETTERS PATENT to William Frederick Henson, of Cavendish Street,
and Henry Poole, of Princes Street, Cavendish Square, both in the
County of Middlesex, for the Invention of "AN IMPROVED MANU-
FACTURE OF CERTAIN TEXTILE FABRICS."
Sealed the 9th July 1872, and dated the 10th May 1872.
PROVISIONAL SPECIFICATION left by the said William Frederick
Henson and Henry Poole at the Office of the Commissioners of
Patents, with their Petition, on the 10th May 1872.
We, WILLIAM FREDERICK HENSON, of Cavendish Street, and HENRY
POOLE, of Princes Street, Cavendish Square, both in the County of
Middlesex, do hereby declare the nature of the said Invention for "Ax
IMPROVED MANUFACTURE OF CERTAIN TEXTILE FABRICS,” to be as follows (that
is to say):-
Our Invention has for its object the introducing of extraneous longi-
tudinal and transverse threads or strands, twisted or plain, into the texture
or body of canvas, calico, or other cotton or closely woven linen cloths,
composed wholly or chiefly of flax, hemp, tow, jute, and cotton yarn, or

page_text: other vegetable fibre, so as to form in union therewith a strengthening
intersecting network or web of cords, arranged in rectangular, diagonal,
or other angular lines crossing the surface at various distances apart,
and consists in interposing the additional strands or cords into the
substance of the hitherto plane textures of linen or cotton cloths and
fabrics aforesaid by weaving the same in with the warp and weft in the
ordinary manner, whereby the said surface texture of the canvas or other
cloth is greatly improved, and rendered more durable by enabling the
wear and tear to be borne by the intersecting binding strands or threads
aforesaid.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Frederick Henson and Henry Poole in
the Great Seal Patent Office on the 9th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
FREDERICK HENSON, of Cavendish Street, and HENRY POOLE, of Princes
Street, Cavendish Square, both in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of May, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said William Frederick Henson and Henry Poole,
Her special licence that we, the said William Frederick Henson and
Henry Poole, our exccutors, administrators, and assigns, or such others
as we, the said William Frederick Henson and Henry Poole, our
executors, administrators, 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 MANUFACTURE OF CERTAIN TEXTILE FABRICS," upon the condition
(amongst others) that we, the said William Frederick Henson and
Henry Poole, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,

page_text: 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 William Frederick Henson and
Henry Poole, 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, that is to say :—
Our Invention has for its object the manufacture of an improved
description of canvas, cotton duck, or goods of a like describtion of
greater strength than heretoforo obtained, which said fabrics are suitable
for sails, tarpaulings, stack and rick cloths, tents and marquees, sacks,
sacking, and bags, shop and window blinds, and mill bands, as also for
similar fabrics for other general purposes.
Our improved canvas, cotton duck, or goods of a like description
above mentioned are manufactured by introducing into the ordinary
body or substance of the fabric whilst weaving the same, either one or
more plain or twisted threads or cords, which wo herein-after call cable
cords, of animal, vegetable, or metallic fibre, or combinations thereof,
and interweaving or binding the same in with the usual warp and weft,
so as to form thereby a check or figure of any desired dimensions, or
lines of any particular distance apart upon the plain groundwork, and
either extending throughout the length and breadth of the said fabric, or
simply in the length or breadth only, or by introducing into the said
fabric tape bands running through the length and breadth of the fabric,
or running through either the length or breadth of the fabric, or disposed
in checks or other figures of any required dimensions woven into the
same fabrics of extra thickness, or with any additional quantity of the
yarn to that employed in the other parts of the fabric, or by a closer
union of the ordinary warp and weft of which the fabric is composed, so
as to form such tape bands as aforesaid.
In conclusion to the foregoing description we would here briefly noto
that we are aware that occasional strong threads similar to the ordinary
warp and weft have before been known and in use in such fabrics as
cambric handkerchiefs, &c., but not in canvas or such goods as above
mentioned for the purpose of strengthening the fabric, or in the form of
twisted thread or cable cords of increased size, or tape bands as employed
ง IIS

page_text: The above-mentioned cable cord is to be introduced into, or the tapo
band formed in, the fabrics above described in the ordinary way in which
materials differing in texture or description have hitherto been introduced
into other woven fabrics, and which manner is well known to and under-
stood by weavers.
Having now fully described and ascertained the nature of this our
said Invention, and the manner in which the same is to be performed and
carried into effect, we would have it clearly understood that we do not
intend to confine ourselves to the precise details herein-before set forth
and described, as the twisted thread, cable cord, and tape band may be
otherwise varied in width, thickness, and distance apart from each other,
or the fabric may be made with a combination of the twisted thread or
cable cord and tape bands, or receive such other modifications as in
practice may be found necessary without departing from the general
principle of this our said Invention; nor do we claim as new and of our
said Invention the exclusive use of the several parts, combinations, and
processes, except where the same are employed in and for the purposes
of our said Invention; but we hereby declare that what we claim as the
Invention secured to us by the herein in part recited Letters Patent is
the improved canvas, cotton duck, or goods of a like description, manu-
factured in the manner and for the purposes herein-before described and
set forth.
