Composed of Vegetable Substances.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and C° Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for IMPROVEMENTS RELATING TO THE WATERPROOFING AND
PRESERVATION OF LINEN AND OTHER FABRICS ROPES HOSE AND OTHER ARTICLES
COMPOSED OF VEGETABLE SUBSTANCES to be as follows:-
This invention relates to an improved process of rendering fabrics and other
materials composed of vegetable substances impermeable and imputrescible.
The said invention is applicable for treating vegetable products generally and
especially linen tent covers and hose; wood, cordage, ropes, cables and string
coverings for metallic cables, and the like.
The said invention has for its object to render vegetable substances impermeable
to water, unattackable by acids, and incorruptible, that is to say incapable of being
affected by dry rot or of decaying and of being attacked by vegetable or animal
ferments.
In order to explain this process I will describe, as an example one of the most
important applications, viz the treatment of linen.
In carrying the said process into practice I infuse in hot water, at the
temperature of 80° Centigrade, a tincture or extract of a substance which is rich
in tannic principles such as extract of chestnuts, of yellow kino, of acacia pods, or
of black or yellow cashoo.
When the said extract is completely dissolved I reduce the density of the liquid.
if too great, to from 1 to 2° Beaumé I then steep the linen or other materials to be
preserved in this liquid for some minutes until the capillary vessels of the fibrous
materials are well filled with the antiseptic substances.
The linen or other materials, after having been dried, are treated in a second bath
composed as follows.
a) If it is desired to obtain a black coating, I add to one hundred kilogrammes
of boiled linseed oil, rendered very siccative by one of the known processes.
one

page_text: hundred kilogrammes of a colour rich in colouring principles deprived of the
metallic oxides, and siccative, for example the black which Th. Chateau calls in his
Technology composition black (which, being a waste product in the manufacture of
artificial ultramarine or of Prussian blue has the advantage of being very
inexpensive) or any other black having the same physical or chemical properties;-
from ten to twenty five kilogrammes of the essence of birch-bark and especially
that obtained in the distillation of the white bark of the Russian birch ;-from six
to ten kilogrammes of a wax, melting at a very high temperature such as the wax
obtained from the Palm-tree which melts at 82° and which has moreover the
advantage of being much cheaper than ordinary wax; or any other substance
having the same physical and chemical properties.
b) If the materials to be impregnated are to be made red, I employ, instead of
composition black, light or dark colcothar or any other red colouring matter having
the same physical and chemical properties.
c) If the materials are to have a green colour imparted to them I employ light
or dark thin English green colouring matter.
I proceed in a similar manner for any other shades, or colours always selecting
colouring matters which have the physical and chemical properties of those
mentioned above.
The boiled linseed oil acts both as a vehicle for the colour and as a drying agent.
The birch tar has the property of remaining elastic at any temperature, even
at 20°; and as neither it nor the wax stick, tent cloths prepared in the bath
composed as just stated are not liable to stick or break either in hot or cold
countries.
In order that the linen articles or material shall be completely impregnated, the
bath in which they are dipped, is raised to the temperature of from 100° to 120°.
They are then passed either to a press or between two cylinders, in order to press
or squeeze out any excess of liquid, leaving between the fibres only the quantity
which is absolutely useful.
If it is desired to give the articles or materials a better appearance than that
which they possess after leaving the press or rollers they are passed into a cold
bath of linseed oil rendered very siccative. This coating must be as thin as
possible..
The various operations described can be performed by hand; but the rapidity
with which they can be executed is such that nothing prevents them from being
performed by mechanical means.
Suitable apparatus is arranged as follows that is to say:-Above a vessel having
a double casing is arranged a system of take-off cylinders and between the two
casings of the said vessel steam circulates. In the vessel is the bath into which
the linen is dipped. The latter passes between the rollers which squeeze out the
excess of the substance with which the, material has been treated and which the
latter has absorbed in the vessel. On leaving the cylinders, the linen is drawn
along in a continuous drying apparatus and then wound upon rollers.
The materials treated according to my process are impermeable and imputrescible,
and these properties are imparted to them without impairing the other and ordinary
qualities of the materials they are rendered neither sticky nor brittle; and their
fibres maintain all their strength, which is not the case when other coatings are
used which are applied only to the surface and do not penetrate the fibres; and
the materials are affected in such a manner that after a little time they lose all
stiffness.

I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,

of my invention for IMPROVEMENTS RELATING TO THE WATERPROOFING AND
PRESERVATION OF LINEN AND OTHER FABRICS, ROPES, HOSE, AND OTHER ARTICLES
COMPOSED OF VEGETABLE SUBSTANCES" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to an improved process of rendering fabrics and other
materials composed of vegetable substances impermeable and imputrescible.
The said invention is applicable for treating vegetable products generally,.
and especially linen tent covers and hose; wood, cordage, ropes, cables and string;
coverings for metallic cables, and the like.
The said invention has for its object to render vegetable substances impermeable
to water, unattackable by acids, and incorruptible, that is to say incapable of being
affected by dry rot, or of decaying, and of being attacked by vegetable or animal
ferments.
In order to explain this process I will describe as an example one of the most
important applications, viz the treatment of linen.
According to the said invention I infuse in hot water at the temperature of
80° Centigrade a tincture or extract of a substance which is rich in tannic
principles, such as extract of chesnuts, of yellow Kino, of acacia pods, or of black or
yellow cashoo.
When the said extract is completely dissolved I reduce the density of the liquid,
if too great, to from 1 to 2° Baumé. I then steep the linen or other materials to
be preserved in this liquid for some minutes until the capillary vessels of the
fibrous materials are well filled with the antiseptic substances.
The linen or other materials, after having been dried, are treated in a second
bath composed as follows:-
--
(a) If it is desired to obtain a black coating I add to one hundred kilogrammes
of boiled linseed oil, rendered very siccative by one of the known processes, one
hundred kilogrammes of a substance rich in colouring matter, and deprived of the
metallic oxides, and siccative, for example the black which Th. Chateau calls in his
Technology composition black (which being a waste product in the manufacture
of artificial ultramarine or of Prussian blue has the advantage of being very
inexpensive); or any other black having the same physical or chemical properties;
from ten to twenty five kilogrammes of the essence of birch-bark, and especially that

to ten kilogrammes of a wax melting at a very high temperature, such as the wax
obtained from the palm tree or from sugar cane, which melts at 82° C and which
has moreover the advantage of being much cheaper than ordinary wax; or any
other substance having the same physical and chemical properties.
(b) If the materials to be impregnated are to be made red, I employ, instead of
composition black, light or dark colcothar or any other red colouring matter having
the same physical and chemical properties.
(c) If the materials are to have a green colour imparted to them I employ light
or dark thin English green colouring matter.
I proceed in a similar manner for any other shades or colours, always selecting
colouring matters which have the physical and chemical properties of those
mentioned above.
The boiled linseed oil acts both as a vehicle for the colour and as a drying agent.
The birch tar has the property of remaining elastic at any temperature even
at 20° below Zero, and as neither it nor the wax sticks, tent cloths, prepared in the
bath composed as just stated are not liable to stick or break either in hot or cold
countries.
In order that the linen articles or materials shall be completely impregnated, the
bath in which they are dipped, is raised to the temperature of from 100 to 120° C..
They are then passed either to a press or between two cylinders in order to press
or squeeze out any excess of liquid, leaving between the fibres only the quantity
which is absolutely useful. If it is desired to give the articles or materials a better
appearance than that which they possess after leaving the press or rollers, they are
passed into a cold bath of linseed oil rendered very siccative. This coating must
be as thin as possible.
The various operations described can be performed by hand; but the rapidity
with which they can be executed is such that nothing prevents them from being
performed by mechanical means.
Suitable apparatus is arranged as follows, that is to say:-Above a vessel having
a double casing is arranged a system of take off cylinders, and between the two
casings of the said vessel steam circulates. In the vessel is the bath into which the
linen is dipped. The latter passes between the rollers which squeeze out the excess
of the substance with which the material has been treated and which the latter has
absorbed in the vessel. On leaving the cylinders, the linen is drawn along in a
continuous drying apparatus and then wound upon rollers.
The materials treated according to my process are impermeable and imputrescible,
and these properties are imparted to them without the other and ordinary qualities
of the materials being impaired; they are rendered neither sticky not brittle, and
their fibres maintain all their strength, which is not the case when other coatings
are used which are applied only to the surface and do not penetrate the fibres;
and the materials are affected in such a manner that after a little time they lose all
stiffness.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
First. The above described process for rendering linen and other fabrics, ropes,
hose and other articles composed of vegetable substances, impermeable and
imputrescible, the said process consisting essentially in successively passing these
materials or substances through two baths, the first of which is characterized by
its richness in antiseptic substances, whilst the second which is siccative is rich in
colouring matters free from metallic oxides.
Second. The baths composed in the manner indicated and exhibiting the physical
and chemical properties defined in the above description, for the purposes specified.

page_text: Third. The succession of operations, above described, which constitute the
improved process.
Fourth. Fabrics or materials prepared by means of the improved process, and
characterized by the fact that they are rendered impermeable and imputrescible and
coloured or dyed as described above, without any of their ordinary properties being
affected by the application of the said process.
