AN IMPROVEMENT IN THE MANUFACTURE OF HOSE OR FLEXIBLE PIPE
Year: 1859

page_text: LETTERS PATENT to Alfred Vincent Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Mechanical Draughts-
man, for the Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF
HOSE OR FLEXIBLE PIPE."-A communication from abroad by Nehemiah
Hunt, of Boston, in the United States of America.
Sealed the 1st May 1860, and dated the 15th November 1859.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 15th November 1859.
I, ALPRED VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane.
in the County of Middlesex, Mechanical Draughtsman, do hereby declare the
nature of the said Invention for "AN IMPROVEMENT IN THE MANUFACTURE of
HOSE OR FLEXIBLE PIPE," to be as follows:-
This Invention relates to the manufacture into sound and durable hose or
flexible pipe of woven multi-ply fabrics. In carrying out the manufacture of
hose from such fabric it has been proposed to coat the fabric with india-rubber
on that side which is to form the inner surface of the pipe, and to secure the
edges together in the form of a lap joint by means of rivets. This mode of
making hose has, however, failed, in consequence of the joint proving leaky,
the water forced into the hose finding an exit through the exposed end of the
fabric. To remedy this defect, it is now proposed to apply to the strip of

page_text: multi-ply fabric that is to form the hose, a sheet or strip of india-rubber of
superior width, and to turn the surplus or overlapping portion of the india-
rubber over the edge of the woven fabric. By this means, when the fabric is
formed into hose the lap joint when formed will effectually prevent the
penetration of the water through it.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Vincent Newton in the Great Seal Patent Office
on the 15th May 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of November, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Alfred Vincent Newton, Her special license that I, the said
Alfred Vincent Newton, my executors, administrators, and assigns, or such
others as I, the said Alfred Vincent Newton, 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "AN IMPROVEMENT IN THE MANUFACTURE OF HOSE OR FLEXIBLE
PIPE," being a communication from abroad by Nehemiah Hunt, of Boston, in
the United States of America, upon the condition (amongst others) that I,
the said Alfred Vincent Newton, 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 Alfred Vincent Newton, do hereby
declare the nature of the 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 Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
This Invention, as communicated to me by my foreign correspondent, relates

page_text: to the manufacture into sound and durable water-tight hose or flexible pipe of
woven multi-ply fabrics, such as are described in the Specification of the Patent
granted to me September Sixth One thousand eight hundred and fifty-nine.
In carrying out the manufacture of hose pipe from such fabrics, it has been
proposed to coat the same with india-rubber on that side which is to form the
inner surface of the pipe, and to secure the edges together in the form of a lap
joint by means of rivets. This mode of making hose pipe has, however,
failed in securing such a joint as would under great pressure be deemed water-
tight, as the water forced into the hose will find an exit through the exposed
edge of the woven fabric, and thereby saturate the fabric at that part and give
it a great tendency to rot. To remedy this defect it is now proposed to apply
to the strip of multi-ply fabric, which is to form the hose, a sheet or strip of
india-rubber, of superior width, and to turn the surplus or overlapping portion
of the india-rubber strip over the edge of the woven fabric. By this means,
when the fabric is formed into hose pipe the lap joint will effectually prevent
the penetration of the water through it.
In the accompanying Drawing, Fig. 1 represents in cross section a piece of
hose or flexible pipe made from woven fabric coated on its inner face with
india-rubber, in the manner hitherto proposed for forming the joint. On
inspecting this Figure it will be seen that the inner edge of the woven fabric
a, a, is left exposed to the column of water flowing through the pipe, the india-
rubber lining b, b, extending only to the edge of the woven fabric. The con-
sequence of which is, as I have stated, that the water when under great
pressure will find a passage into and even through the joint. To ensure a
sound water-tight joint it is now proposed to prepare the compound material,
as shewn at Fig. 2, which represents in cross section a piece suitable for
conversion into hose pipe. a, a, is a strip of multi-ply woven fabric, covered
on one side with a strip of sheet rubber b, one edge of which extends beyond
the woven fabric, as shewn at 6*. To convert this compound fabric into hose
pipe, the part of sheet rubber is first lapped over the edge of the fabric a,
as shewn at Fig. 3, and the opposite edges of the compound fabric are then
brought together, as shewn at Fig. 4 (that edge which is covered by the sheet
rubber forming the inner lap of the pipe), and firmly secured by copper or
other rivets. By this means it will be seen that no portion of the woven
fabric is presented to the water, and no escape thereof can therefore take place
through the joint so long as the india-rubber coating remains sound. Thus
the woven fabric will be exposed to dampness from the outer surface only, and
from this it may be readily expelled by evaporation, and all tendency to rot at
the joint will be avoided.

page_text: Having now set forth the nature of the Invention of an improvement in the
manufacture of hose or flexible pipe, as communicated to me by my foreign
correspondent, and explained the manner of carrying the same into effect, I
wish it to be understood, that under the above in part recited Letters Patent,
I claim the means herein described for obtaining a sound water-tight joint in
hose or flexible pipe manufactured from multi-ply fabrics.
In witness whereof, I, the said Alfred Vincent Newton, have hereunto
set my hand and seal, the Fifteenth day of May, in the year of our
Lord One thousand eight hundred and sixty.
