Year: 1874

page_text: LETTERS PATENT to Bernhard Kaposi, of No. 9, Sparsholt Road,
Crouch Hill, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN THE PREPARATION OF MACHINE OILS."- A com-
munication from abroad by Melchior Klosak, of Vienna, Austria.
PROVISIONAL SPECIFICATION left by the said Bernhard Kaposi at
the Office of the Commissioners of Patents, with his Petition, on
the 16th September 1874.
I, BERNHARD KAPOSI, of No. 9, Sparsholt Road, Crouch Hill, in the
County of Middlesex, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE PREPARATION OF MACHINE OILS," to be as
follows:-
This Invention relates to a process of preparing vegetable oils, such
as olive oil or rape oil for use in lubricating machinery by the removal
of impurities which are usually present in sucli oils, and which not only

page_text: diminish their lubricating power, but also tend to corrode or otherwise
injure the metallic surfaces to which they are applied.
The process consists in the first place in repeated washings of the oil
with pure water, the oil being decanted after each washing, after which
it is filtered successively through fragments of granite or other hard
stone, charcoal, felt, and cotton or other fibrous material. In order to
prevent the oil thus purified from being appropriated to other purposes.
than lubrication, as for example, to lighting or for use as food, the crude
oil may be mixed before being treated as above described, with petroleum
and with strongly scented oils, such as that of rosemary.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Bernhard Kaposi in the Great Seal Patent Office
on the 10th March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BERNHARD
KAPOST, of No. 9, Sparsholt Road, Crouch Hill, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of September, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Bernhard Kaposi, Her special license
that I, the said Bernhard Kaposi, my executors, administrators, and
assigns, or such others as I, the said Bernhard Kaposi, 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 for "IMPROVEMENTS IN
THE PREPARATION OF MACHINE OILS,” a communication to me from abroad
by Melchior Klosak, of Vienna, Austria, upon the condition (amongst
others) that I, the said Bernhard Kaposi, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and scals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,

page_text: 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 Bernhard Kaposi, 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 thereof, that is to say :-
This Invention relates to a process of preparing vegetable oils, such as
olive oil or rape oil for use in lubricating machinery by the removal of
impurities which are usually present in such oils, and which not only
diminish their lubricating power, but also tend to corrode or otherwise
injure the metallic surfaces to which they are applied.
The process consists in the first place in repeated washings of the oil
with pure water, the oil being decanted after each washing, after which
it is filtered successively through fragments of granite or other hard
stone; charcoal, felt, and cotton or other fibrous material. In order to
prevent the oil thus purified from being appropriated to other purposes
than lubrication, as for example, to lighting or for use as food, the crude
oil may be mixed before being treated, as above described, with petroleum
and with strongly scented oils, such as that of rosemary.
Having thus described the nature of this Invention and in what
manner the same is to be performed, as communicated to me by my
foreign correspondent, I claim the before described process for preparing
machine oils, by first washing the same in water and then filtering
successively through hard stone, charcoal, felt, and cotton or other
fibrous materials.
In witness whereof, I, the said Bernhard Kaposi, have hereunto
set my hand and seal, this Eighth day of March, in the year
