page_text: LETTERS PATENT to Henry Henson Henson, of Parliament Street, in the
City of Westminster, Engineer, for the Invention of "AN IMPROVEMENT
IN THE MANUFACTURE OF FABRICS SUITABLE FOR GOODS WRAPPERS AND OTHER
PRODAS PAD WHICH CANUAR WAS BEEN OR MAY BE EMPLOYED."
Sealed the 13th November 1855, and dated the 25th May 1855.
PROVISIONAL SPECIFICATION left by the said Henry Henson Henson at
the Office of the Commissioners of Patents, with his Petition, on the
25th May 1855.
I, HENRY HENSON HENSON, of Parliament Street, in the City of Westminster,
Engineer, do hereby declare the nature of the said Invention for "AN IMPROVE-
MENT IN THE MANUFACTURE OF FABRICS SUITABLE FOR GOODS WRAPPERS AND OTHER
PURPOSES FOR WHICH CANVAS HAS BEEN OR MAY BE EMPLOYED" to be as follows:-
My improvement is based upon an Invention for which Letters Patent were
granted to me for England, 5th November 1846, which consisted mainly in the
manufacture of a fabric composed partly of wire and partly of hemp, or other
similar fibrous materials.
Now, the present Invention consists in coating or covering such wires before.
being woven into a fabric together with hemp or other suitable fibrous
material, with india-rubber, gutta percha, or other preserving material or
substance, or with a wrapper of tape or fibrous material, subsequently coated

page_text: or not with some preserving substance or material; or, instead of any pre-
serving coating of the kind before referred to, I employ galvanized wire, or
wire coated with some metal which will protect it from oxydation.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Henson Henson- in the Great Seal Patent Office
on the 21st November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
HENSON HENSON, of Parliament Street, in the City of Westminster, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of May, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Henson Henson, Her special licence that I, the said Henry
Henson Henson, my executors, administrators, and assigns, or such others
as I, the said Henry Henson Henson, my 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
night 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 IMPROVEMENT IN THE MANUFACTURE OF FABRICS SUITABLE FOR GOODS'
WRAPPERS AND OTHER PURPOSES FOR WHICH CANVAS HAS BEEN OR MAY BE EMPLOYED,"
upon the condition (amongst others) that I, the said Henry Henson Henson,
by an instrument in writing under my hand and seal, 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 I, the said Henry Henson Henson, 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 thereof, that is to say:-
My improvement is based upon an Invention for which Letters Patent were
granted to me for England, dated the Fifth of November, One thousand eight
hundred and forty-six, which consisted mainly in the manufacture of a fabric
composed partly of wire and partly of hemp or other similar fibrous materials.

page_text: Now, the present Invention consists in coating or covering such wires before
being woven into a fabric together with hemp or other suitable fibrous material,
with india-rubber, gutta percha, or other preserving material or substance, or
with a wrapper of tape or fibrous material, subsequently coated or not with
some preserving substance or material; or, instead of any preserving coating of
the kind before referred to, I employ galvanized wire, or wire coated with some
metal which will protect it from oxidation.
The manner in which I proceed is as follows:-I take wire of any gauge
that is capable of being woven, and coat it with a solution of caoutchouc or
with gutta percha, by fitting inside a box or trough a coil or reel with wire
thereon, and for every wire I provide a die, or simply pierce a hole in the
bottom of the trough. I run into the trough a quantity of the coating solution
or gutta percha, and keep up the temperature at such a degree that the caout-
chouc or gutta percba will readily adhere to and run out with the wires, for
which purpose I introduce hot air or steam into the trough; or the trough may
be surrounded with a jacket, into which the heating agent may be admitted.
I pass an end of the wire from the reels or coils through the dies or apertures
in the bottom of the trough and draw the wires out, when they will be found
coated and in a fit state to be woven for the purpose of my Invention, together
with hempen or other suitable fibres.
Instead of caoutchouc or gutta percha any other preserving material which
will become sufficiently fluid under heat may be applied in the manner just
described; or, in place of coating the wires directly, I wrap round them a strip
of tape or fibrous material saturated with any waterproof and preserving sub-
stance or composition either before they are wrapped round the wires, or the
coating of waterproof or preserving material may be applied thereon after they
have been so wrapped, either in the manner first described; or a preserving
composition or material may be laid thereon by a brush, or it may be applied
by the wire and covering being simply dipped in the preserving composition or
material; or, instead of coating the wires in the manner before stated, I employ
galvanized iron wire, or wire coated with some other metal which will preserve
it from oxidation.
Wires prepared in either of the manners aforesaid may be employed together
with any fibrous threads in the weaving of cloths, at such intervals apart both
in the warp and in the weft, or in either of them, according to the strength
desired in the finished fabric. Cloths thus made will possess great strength, and
will not be liable to become rotten from oxidation of the metal woven there-
with, and are well adapted for goods' wrappers, sacks, sails, tents, and other
like articles exposed to rough wear.

page_text: And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim the employment of
wire coated or covered with a material or composition to prevent oxidation
together with fibrous threads in the manufacture of fabrics suitable for goods
wrappers and other purposes for which canvas has been or may be employed.
In witness whereof, I, the said Henry Henson Henson, have hereunto
set my hand and seal, this Twenty-first day of November, One thousand
eight hundred and fifty-five.
