We. WILLIAM THOMS HENDRY.: of 38. .Upper.Thanie's Street in..the::City
of London. Engineer, and: ROBERT HENRY HANCOCK of 23:Great Percy
Street, Pentonville, in the County of Middlesex... India-qubber Manufacihrer.
do hereby declare the nature of the said: Invention for IMPROVEMENTS IN) THE
MANUFACTURE OF FLEXIBLE TUBES OR HOSE PIPES," to be as follows: 7)
This Invention relates to certain improvements in the manufacture of
production of flexible pipes, suitable for hose pipes and other purposes where
flexible pipes or tubes are used.
In carrying out this Invention we take a flexible tube or hose. -wovch
either single, double, or of more thicknesses, or otherwise manufactured from
flax. cotton. or other suitable fibrous material, and satorate the same with
a solution of india-rubber, gutta percha, or other good waterproofing material
suitable for the purpose. We then take a tube of imlian-rubber. the external
diameter of which corresponds or nearly corresponds with the internal diameter

drawn through the first-mentioned tube in any manner found most con-
venient. One or more woven or other tubes may be drawn through each
other to increase the strength if necessary. One end of the compound tube
thus formed is now plugged or otherwise closed tight. We then fill the pipe
with air, water, or other suitable gas or fluid, or with sand or other pul-
verised substance, at a sufficient pressure to unite firmly the india-rubber tube
to the woven or outer flexible tube or tubes. We then. if desired, cover the
woven or outer flexible tube with india-rubber, gutta percha, or other flexible
material impervious to water, either before or after removing the internal
pressure, as found most convenient. The india-rubber or other tube intro-
duced into the interior of the woven or other flexible tube, and the india-
rubber or other coating on the exterior of the outer flexible tube may be
previously vulcanized, or the hose manufactured as above described may be
subsequently subjected to the process commonly known as vulcanizing.
According to another arrangement we take, first, a flexible hose, previously
inanufactured, and fill the same at a pressure with air. water, or other
suitable gas or fluid, or with sand or any pulverised substance. We then
close both ends of the tube, which now presents the appearance of a solid
body, and this we employ as a material over which to manufacture flexible
tubing or hose. We then proceed as follows:-Over the mandril so formed
we manufacture a tube of india-rubber, gutta percha, or other flexible
material, or from a textile fabric previously coated with india-rubber, gutta
percha, or other suitable waterproofing material. We then proceed to weave
or braid over the tube so formed cotton, flax. or other textile fabric, having,
if necessary. previously rendered the india-rubber or other tube adhesive, or
adhesive matter may be introduced during the process of weaving or braiding.
so that the weaving or braiding may be made to adhere to the india-rubber
or other flexible tube previously formed on the mandri!. If found desirable.
the woven or braided tube may now be coated with india-rubber, gutta percha,
or other flexible material. The internal pressure is then removed from the
flexible mandril, which mandril we are then enabled to withdraw, and leave
a perfect flexible tube or hose. The flexible tube or hose. if necessary, is
subsequently subjected to the process commonly known as vulcanizing, or the
india-rubber used in the manufacture of this flexible hose may have been
previously vulcanized.

Thoms Hendry and Robert Henry Hancock, our executors, administrators, or
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 halslands, and Isle of Man, an Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF FLEXIBLE TUBES OR HOSE PIPES," upon
the condition (amongst others) that we, the said William Thoms Hendry and
Robert Henry Hancock, by an instrument in writing under our hands and
seals, should particularly describe and ascertain the nature of the said In-
vention, 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 Thoms Hendry and Robert
Henry Hancock, 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 said Invention relates to certain improvements in the manufacture or
production of flexible tubes, suitable for hose pipes and other purposes where
flexible pipes or tubes are used.
In carrying out our Invention we take a flexible tube or hose, woven either
single, double. or of more thicknesses. or otherwise manufactured from flax,
cotton, or other suitable fibrous material, and saturate the same with a
solution of india-rubber, gutta percha, or other good waterproofing material
suitable for the purpose. We then take another tube composed of india-

page_text: rubber or a combination of india-rubber and gutta percha, or other suitable
material, the external diameter of which tube corresponds or nearly cor-
responds to the internal diameter of the first-mentioned flexible tube. This
india-rubber tube is now drawn through the first-mentioned tube in any
manner found most convenient.
One or
more woven or other tubes may
thus be drawn through each other to increase the strength if necessary. One
end of the compound tube thus formed is now plugged or otherwise closed
tight, and we then fill the tube with water, steam, air, or other suitable gas,
vapor, or fluid, or with sand or other pulverized substance, at a sufficient
pressure to unite firmly the india-rubber tube to the woven or outer flexible
tube or tubes. We then, if found desirable, cover the woven or outer flexible
tube with india-rubber or gutta percha, or a combination of india-rubber and
gutta percha or other suitable compound or material impervious to water,
such covering being accomplished either before or after removing the internal
pressure. as found most convenient. The india-rubber or other tube which
has been introduced into the interior of the woven or other flexible tube, and
the india-rubber or other coating on the exterior of the outer flexible tube
may be previously vulcanized, or the hose manufactured as above described
may be subsequently subjected to the process commonly known as vul-
canizing.
According to another process of manufacture we take. first, a flexible hose
previously manufactured, and fill the same at a requisite pressure with air,
water, steam, or other suitable gas. vapor, or fluid, or with sand or other
pulverized substance. We then close both ends of the tube, which now
presents the appearance of a solid body, and this we employ as a mandril,
over which to manufacture flexible tubing or hose. Over the mandril so
formed we manufacture a tube composed of india-rubber, gutta percha, or
other flexible material, or of any combination of india-rubber, guita percha.
& other flexible material. or of a textile fabric previously coated with india-
rubber, gutta percha, or other suitable waterproofing material. We then proceed
to weave or braid over the tube so formed cotton, flax, or other textile fabric,
having, if necessary. previously rendered the india-rubber or other tube adhesive.
or introduced adhesive matter during the process of weaving or braiding, so that
the weaving or braiding may be made to adhere to the india-rubber or other
flexible tube previously formed on the mandril. If found desirable, the
woven or braided tube may now be coated with india-rubber. gutta percha, or
other flexible material. The internal pressure is then removed from the
flexible mandril, which may then be withdrawn, leaving a perfect flexible tube
or hose. This flexible tube or hose, if necessary, is subsequently subjected to

page_text: the process commonly known as vulcanizing, or the india-rubber used in the
manufacture of this flexible hose may have been previously vulcanized.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried
into effect, we would observe. in conclusion, that we do not confine or restrict
ourselves to the precise details or arrangements which we have had occasion
to describe or refer to, as many variations may be made therefrom without.
deviating from the principles or main features of our said Invention: but
what we consider to be novel and original, and therefore claim as the Invention
secured to us by the herein-before in part recited Letters Patent. is.-
First, the systems or modes of manufacturing flexible tubes or hose pipes,
as herein-before described.
Second, the system or mode of internally coating a tube which has been
previously manufactured with india-rubber, gutta percha, or other flexible
waterproof material, as herein-before described.
Third, the system or mode of uniting an india-rubber. gutta percha. or
other flexible tube, with an external woven tube by means of internal pressure
obtained from any suitable fluid. vapor, or gas, or from pulverized material
introduced. under pressure into the tube, as herein-before described.
Fourth, the application and use of a flexible mandril, as herein-before
described, in the manufacture of flexible tubes or hose pipes.
In witness whereof, we, the said William Thoms Hendry and Robert
Henry Hancock, have hereunto set our hands and seals, the Second
day of January, One thousand eight hundred and fifty-eight.
