page_text: LETTERS PATENT to James Henson, of Watford, in the County of Herts,
and William Frederick Henson, of 15, New Cavendish Street, Portland
Place, and 18, Parliament Street, Westminster, Civil Engineers, for the
Invention of "MANUFACTURING CANVAS AND OTHER FABRICS FOR TARPAULINGS,
SACKS, RICK-CLOTHS, SHIP SAILS, AND FOR OTHER PURPOSES; AND ALSO FOR
UNITING THE EDGES OF THE SAME."
Sealed the 11th January 1861, and dated the 17th July 1860.
PROVISIONAL SPECIFICATION left by the said James Henson and William
Frederick Henson at the Office of the Commissioners of Patents, with
their Petition, on the 17th July 1860.
We, JAMES HENSON, of Watford, in the County of Herts, and WILLIAM
FREDERICK HENSON, of 15, New Cavendish Street, Portland Place, and 18,
Parliament Street, Westminster, Civil Engineers, do hereby declare the nature
of the said Invention for "MANUFACTURING CANVAS AND OTHER FABRICS FOR
TARPAULINGS, SACKS, RICK-CLOTHS, SHIP SAILS, AND FOR OTHER PURPOSES AND ALSO
FOR UNITING THE EDGES OF THE SAME," to be as follows:-
The object of our Invention is to give to canvas and other fabrics, woven or
otherwise, whether manufactured of cotton, linen, wool, hemp, silk, or other
materials, or any combination thereof, durability and increase of strength by
manufacturing such materials by the process of weaving into squares or other
suitable forms, whereby a head or ridge or flat surface is raised upon the
surface of such materials when woven.
We also unite the edges of the fabrics or materials, either by lapping or
fishing by means of a solution of india-rubber or gutta percha, or in combination

page_text: with shellac, or other suitable substance, such as marine glue, ether alone or
in combination with any of the before-mentioned substances. After having
applied to the edges of the fabrics a solution, we pass the same through rollers
for the purpose of uniting the edges and making a seam or joint of great
strength and durability, rendering the present mode of sewing quite unnecessary.
In some cases, where desirable, we fish and sew the edges or joints.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Henson and William Frederick Henson in the Great
Seal Patent Office on the 17th January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JANES
HENSON, of Watford, in the County of Herts, and WILLIAM FREDERICK HENSON,
of 15, New Cavendish Street, Portland Place, and 13, Parliament Street,
Westminster, Civil Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of July, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
James Henson and William Frederick Henson, Her special licence that we, the
said James Henson and William Frederick Henson, our executors, adminis-
trators, and assigns, or such others as we, the said James Henson and William
Frederick Henson, our executors, administrators, and assigns, should at any timo
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 "MANUFACTURING CANVAS AND OTHER
FABRICS FOR TARPAULINGS, SACKS, RICK-CLOTHS, SHIP SAILS, AND FOR OTHER PUB-
POSES, AND ALSO FOR UNITING THE EDGES OF THE SAME," upon the condition (amongst
others) that we, the said James Henson and William Frederick Henson,
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, and in what manner the samo was to be per-
formed, 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 James Henson and William Frederick
Henson, do hereby declare the nature of our said Invention, and in what

page_text: manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say):-
We give to canvas and other fabrics or materials, either woven or otherwise,
manufactured of cotton, linen, wool, flax, silk, or other materials, or any com-
bination thereof, durability and increase of strength, by manufacturing them
into squares or other suitable forms, whereby a bead, ridge, or flat surface is
raised upon the surface of such materials when manufactured.
We also unite the edges of the fabrics or materials by lapping or fishing them
with a solution of caoutchouc or gutta percba, or either or both the said sub-
stances in combination with shellac or other suitable substance, such as marine
gluc, either alone or in combination with any of the before-mentioned substances.
After having applied the solution to the edges of the fabric or material, we pass
the same through or between suitable rollers for the purpose of uniting them
and making a seam or joint of great strength and durability, thus rendering
the present mode of sewing quite unnecessary. If found desirable, the edges
or joints may be fished and sewn, and the solution added.
Having thus fully described the nature of our said Invention, and the
manner in which the same is to be performed, we desire it to be understood
that we claim as our Invention, and which to the best of our knowledge and
belief has not been hitherto used within the realm, the manufacture of canvas
and other fabrics or materials of any suitable shape or dimensions, with a bead,
ridge, or flat surface raised on the surface thereof, and uniting their edges by
lapping or fishing them with a solution of caoutchouc or gutta percha, or either
or both the said substances in combination with shellac, marine glue, or similar
articles.
In witness whereof, I, the said James Henson, for and on behalf of
myself and the said William Frederick Henson, have hereunto set
my hand and seal, this Seventeenth day of January, in the year
of our Lord, One thousand eight hundred and sixty-one.
Witness,
EDWP. T. HUGHES,
