for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF TUBES OR
PIPES."
Sealed the 21st December 1860, and dated the 31st July 1860.
PROVISIONAL SPECIFICATION left by the said William Picksione at
the Office of the Commissioners of Patents, with his Petition, on the
31st July 1860.
I, WILLIAM PICKSTONE, of 32, York Street, Manchester, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
TUBES OR PIPES," to be as follows:-
This Invention has for its object improvements in the manufacture of tubes
or pipes. For this purpose I employ canvas, or felt, or paper, or any other textile
fabric, coated with tar, pitch. india-rubber, gutta percha, or any similar material,
and wind it spirally in layers, together with layers of thin metal, such as brass
or steel, also wound spirally. The pipes may be made of alternate layers of
textile fabric and metal or otherwise, according to the strength required, and
longitudinal layers, either of metal or of textile material, may be introduced
between the spiral layers if required.

TO ALL TO WHOM THESE PRESENTS: SHALL COME, 1. WILLIAM

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first 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 me,
the said William Pickstone, Her special licence that I, the said William
Pickstone, my executors, administrators, and assigns, or such others as I,
the said William Pickstone, 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
might make, use, exercise, and. vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
"IMPROVEMENTS IN. THE MANUFACTURER OF TUBES OR PIPES," upon the
condition (amongst others) that I, the said William Pickstone, my executors
or administrators, by an instrument in writing under my, 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 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.
for
NOW KNOW YE, that I, the said William Pickstone, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:
This Invention has for its object improvements in the manufacture of tubes
or pipes. For this purpose employ canvas,, or felt, or paper, or any other
textile fabric, coated with tar, pitch, india-rubber, gutta percha, or any similar
material, and wind it spirally in layers, together with layers of thin metal, such
as brass or steel, also wound spirally. The pipes may be made of alternate layers
of textile fabric and metal or otherwise, according to the strength required, and
longitudinal layers, either of metal or of textile material, may be introduced
between the spiral layers if required.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.

page_text: Narrow strips of canvas, or felt, or paper, or other textile fabric are employed,
which are coated with a suitable cement according to the purpose to which the
pipes or tubes made according to my Invention are to be applied; thus, where
the tubes or pipes require to be waterproof, a solution of india-rubber or of
gutta percha may be employed, or pitch, or tar, or other matters may be used as
cement for causing succeeding layers of textile fabric to adhere to each other;
or paste or glue or other matters may be employed when the tubes or pipes
are not desired to be waterproof. The narrow strips of the textile fabric
employed are wound spirally around a suitable mandril or form, and each
succeeding layer may be wound in the same or in the opposite direction to the
previous one; I prefer to wind the succeeding layer in the opposite direction
to that in which the previous layer has been wound. In all cases care is to
be taken to break or cover the joints or edges of the textile fabric of the
previous layer by the next layer. I would here state that it is not new thus
to make pipes or tubes by lapping one layer of textile fabrics spirally over
another layer or layers thereof.
My Invention consists in the introduction of strips or narrow fillets of sheet
metal, such as brass or steel or other metal, which are wound spirally in
between the layers of textile fabric, in order to obtain pipes or tubes of great
strength and of any desired length, using more or less layers of textile fabric
and more or less layers of thin sheet metal, according to the purpose to which
the pipes or tubes so made are intended to be applied.
In witness whereof, I, the said William Pickstone, have hereunto set my
hand and seal, this Twenty-fifth day of January, in the year of our
Lord One thousand eight hundred and sixty-one.
WILLIAM PICKSTONE. (L.S.)
