IMPROVEMENTS IN THE PREPARATION AND UTILIZATION OF CERTAIN VEGETABLE AND BITUMINOUS PRODUCTS
Year: 1868

page_text: LETTERS PATENT to Joseph Rogers, of Baxter Road, Islington, for the
Invention of "IMPROVEMENTS IN THE PREPARATION AND UTILIZATION OF
CERTAIN VEGETABLE AND BITUMINOUS PRODUCTS."
Sealed the 25th September 1868, and dated the 23rd April 1868.
PROVISIONAL SPECIFICATION left by the said Joseph Rogers at the
Office of the Commissioners of Patents, with his Petition, on the
23rd April 1868.
I, JOSEPH ROGERS, of Baxter Road, Islington, do hereby declare the
nature of my said Invention for "IMPROVEMENTS IN THE PREPARATION AND
UTILIZATION OF CERTAIN VEGETABLE AND BITUMINOUS PRODUCTS," to be as
follows:-
My improvements relate to the utilization and employment of certain
residual products obtained in and resulting from the treatment of vege-
table oils, such as cotton seed oil, and from the distillation and refining
of crude, mineral, and bituminous products such as coal oil and
petroleum.

page_text: Now my Invention consists, firstly, in the admixture of the before-
mentioned residual products, or of any two or more of them in such
proportions as shall produce a material or materials which shall possess
such qualities as shall render them applicable to the purposes required.
As an instance I have found that when I employ a mixture consisting
of about 2 parts by weight of the solid residium resulting from the treat-
ment of vegetable oils, such, for example, as the solid foots from cotton
seed oil, and of about one part by weight of the fluid residium or liquid
foots resulting from the rectification of petroleum or coal oil I obtain a
material capable of being employed for coating or impregnating woven
fabrics, fibrous materials, ropes or yarns, and paper; also for the coating
of wire for telegraphic purposes, iron and metallic work, ships' holds and
bottoms, wood, and masonry, and when such before-mentioned mixture,
compound, or material has been subjected to the action of solvents such
as benzole or coal tar naptha, a solution is obtained which may be
employed as a covering or varnish for iron and metals, wood, masonry,
textile and woven fabrics, fibrous materials, and paper.
My Invention further consists in the admixture and incorporation
with the compound or compounds obtained in the manner herein-before
mentioned of gutta percha or of india-rubber, or of mixtures thereof, for
the purpose of obtaining a material suitable for the covering or coating
of telegraphic wires, or for the coating or covering of ships' bottoms or
holds of ships, and of iron or metal work, of wood or masonry, of paper,
and of fibrous materials, and of woven fabrics.
The proportions which I have found to give good results are about
6 parts by weight of the mixture or compound herein-before mentioned
with about one part by weight of gutta percha or of india-rubber, or with
about a similar proportion of an equal mixture of the same, and when
such before-mentioned mixture, compound, or material has been sub-
jected to the action of solvents, such as benzole or coal tar naptha, a
solution is obtained which may be employed as a covering or varnish for
iron and metals, wood, masonry, textile and woven fabrics, fibrous
materials, and paper.
Although I have given proportions which I have found to give
good results, these may be varied according to the purposes to which
the resulting compound or compounds are intended to be applied.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Rogers in the Great Seal Patent Office on
the 15th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
ROGERS, of Baxter Road, Islington, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of April, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Rogers, Her special license that
I, the said Joseph Rogers, my executors, administrators, and assigns, or
such others as I, the said Joseph Rogers, my 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 Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE PREPARATION AND
UTILISATION OF CERTAIN VEGETABLE AND BITUMINOUS PRODUCTS," upon the con-
dition (amongst others) that I, the said Joseph Rogers, my executors or
administrators, by an instrument in writing under my hand and seal,
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 I, the said Joseph Rogers, 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, that is to say :-
My said Invention relates to the utilisation and employment of
certain residual products, such, for example, as cotton pitch, obtained in
and resulting from the treatment of vegetable oils, such as cotton seed
oil, and from the distillation and refining of crude mineral and
bituminous products, such as coal oil and petroleum, and consists,
firstly, in the admixture of the before-mentioned residual products, or of
any two or more of them together, in such proportions as shall produce

page_text: a material or materials which shall possess such qualities as shall render
them applicable to the purposes herein mentioned.
I have found that when I employ a mixture consisting of about two
parts by weight of the solid residuum before referred to and resulting
from the treatment of vegetable oils, such, for example, as the solid foots
from cotton seed oil or cotton pitch, and of about one part by weight of
the fluid residuum or liquid foots resulting from the rectification of
petroleum or of coal oil, I obtain a material capable of being employed
for coating or impregnating woven fabrics, fibrous materials, ropes or
yarns, and paper, for the coating iron and metallic work, ships' holds
and bottoms, wood, and masonry. When such before-mentioned mixture,
compound, or material has been subjected to the action of solvents, such
as benzole or coal tar naptha, a solution is obtained which may be
employed as a covering or varnish for iron and metals, wood, masonry,
textile and woven fabrics, fibrous materials, and paper.
My Invention further consists in the admixture and incorporation
with the compound or compounds herein-before mentioned of gutta
percha or india-rubber, or mixtures of the same, for the purpose of
obtaining a material suitable for the covering or coating of telegraphic
wires, or for the coating or covering of ships' bottoms, or holds of ships,
or of iron or metal work, of wood or masonry, of paper, and of fibrous
materials, and of woven fabrics.
The proportions which I have found to give good results are about six
parts by weight of the mixture or compound herein-before mentioned
with about one part by weight of gutta percha or of india-rubber, or with
about a similar proportion of an equal mixture of the same, and when
such before-mentioned mixture, compound, or material has been
subjected to the action of solvents, such as benzole or coal tar naptha,
a solution is obtained which may be employed as a covering or varnish
for iron and metals, wood, masonry, textile and woven fabrics, fibrous
material, and paper.
Although I have given such proportions which I have found to give
good results, it is evident that they may be varied according to the
several purposes to which the resulting compound or compounds are
intended to be applied.
Having now described and particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider

page_text: to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the
application and use of cotton pitch or other residual products resulting
from the treatment of vegetable oils, and also the residual products
resulting from the refining of bituminous or similar mineral products,
in the manner and for the purpose substantially as herein-before
described.
In witness whereof, I, the said Joseph Rogers, have to this my
Specification set my hand and seal, this First day of October,
One thousand eight hundred and sixty-eight.
JOSEPH ROGERS. (L.s.)
