THE PRODUCTION OF A NEW PAINT OIL
Year: 1858

page_text: LETTERS PATENT to William Rhodes, of the City of Manchester, in the
County of Lancaster, Oil Refiner, and Henry Napier, of the City of
Brooklyn, in the State of New York, in the United States of America,
Manufacturing Chemist, for the Invention of "THE PRODUCTION OF A
NEW PAINT OIL."
Sealed the 15th June 1858, and dated the 4th February 1858.
PROVISIONAL SPECIFICATION left by the said William Rhodes and
Henry Napier at the Office of the Commissioners of Patents, with their
Petition, on the 4th February 1858.
We, WILLIAM RHODES, of the City of Manchester, in the County of
Lancaster, Oil Refiner, and HENRY NAPIER, of the City of Brooklyn, in tho
State of New York, in the United States of America, Manufacturing Chemist,
do hereby declare the nature of the said Invention for "THE PRODUCTION
OF A NEW PAINT OIL," to be as follows:-
We employ the volatile oil of resin which is formed in the process of
decomposing resin for the purpose of making resin oil; this oil we free from
an acid principle contained in it (which acid principle unfits it for our purpose)
by means of an alkali in the manner following:-We add to one hundred
gallons of the volatile oil eighteen pounds of the soda of ash of commerce in a
still or other vessel, and applying heat we cause the volatile oil to distil over,
condensing it in the usual way; the alkali neutralizes the acid and the oil is

page_text: rendered pure and fit for the further process. To give the purified oil
sufficient body for the purposes of painters and others, we take five hundred
pounds of any of the resins of commerce, the various qualities of which may
be used as fine light colours or common dark ones may be required, melt the
same in any convenient vessel by as gentle a heat as practicable, and add to
the aforesaid five hundred pounds of resin one hundred gallons of the purified
volatile oil, the two being properly mixed and amalgamated; the heat must be
withdrawn and the mass be allowed to cool, the resulting compound is the
"new paint oil" ready for use in the usual manner employed in the case
of other paint oils. "Mineral oil," "coal oil" (or "coal naptha "), "volatile
tar," or "volatile peat oil" may also be used for the purpose when freed from
any acid principle, and supplied with the resin as stated above.
We prefer
the volatile oil of resin on account of its being less objectionable in odour than
the others named, but we do not restrict ourselves to its use alone, as any
other volatile oils or "napthas" as above named inay be used on the principle
of our Invention.
Neither do we limit ourselves to soda ash as the alkali to be employed,
caustic soda, potash, caustic potash, and caustic lime being capable of applica-
tion in the neutralization of the acid principle.
Neither do we restrict ourselves to the precise quantities of ingredients
mentioned, as these may be slightly varied without departing from the principle
of our Invention, nor to any particular form of apparatus, but what we claim is
the combination of the purified volatile oils or "napthas" as above enumerated,
with resin of commerce for the formation of a "new paint oil" substantially
as above described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Rhodes and Henry Napier in the Great Seal Patent
Office on the 2nd August 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
RHODES, of the City of Manchester, in the County of Lancaster, Oil Refiner,
and HENRY NAPIER, of the City of Brooklyn, in the State of New York, in
the United States of America, Manufacturing Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of February, One thousand eight
hundred and fifty-eight, in the twenty-first year of Her reign, did, for Herself,
Her heirs and successors, give and grant unto us, the said William Rhodes

page_text: and Henry Napier, Her special licence that we, the said William Rhodes and
Henry Napier, our exccutors, administrators, and assigns, or such others as
we, the said William Rhodes and Henry Napier, 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, excrcise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "THE PRODUCTION OF A NEW PAINT OIL," upon the condition
amongst other things, that we, the said William Rhodes and Henry Napier,
by an instrument in writing under our hands and seals, 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 we, the said William Rhodes and Henry Napier,
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 :-
We employ the volatile oil of resin which is formed in the process of
decomposing resin for the purpose of making resin oil; this oil we free from
an acid principle contained in it (which acid principle unfits it for our purpose)
by means of an alkali in the manner following:-We add to one hundred
gallons of the volatile oil eighteen pounds of the soda of ash of commerce in a
still or other vessel, and applying heat we cause the volatile oil to distil over,
condensing it in the usual way; the alkali neutralizes the acid and the oil is
rendered pure and fit for the further process. To give the purified oil
sufficient body for the purposes of painters and others we take five hundred
pounds of any of the resins of commerce, the various qualities of which may
be used as fine light colours or common dark ones may be required, melt the
same in any convenient vessel by as gentle a heat as practicable, and add to
the aforesaid five hundred pounds of resin one hundred gallons of the purified
volatile oil, the two being properly mixed and amalgamated the heat must be
withdrawn and the mass be allowed to cool, the resulting compound is the
"new paint oil" ready for use in the usual manner employed in the case of
other paint oils. "Mineral oil," "coal oil" (or "coal naptha"), "volatile tar," or
"volatile peat oil" may also be used for the purpose when freed from any acid
principle, and supplied with the resin as stated above. We prefer the volatile
oil of resin on account of its being less objectionable in odour than the others
named, but we do not restrict ourselves to its use alone as any of the volatilo

page_text: oils or "napthas" as above named may be used on the principle of our
Invention. Neither do we limit ourselves to soda ash, or the alkali to be
employed, caustic soda, potash, caustic potash, and caustic lime being capable
of application in the neutralization of the acid principle. Neither do wo
restrict ourselves to the precise quantities of ingredients mentioned, as these
may be slightly varied without departing from the principle of our Invention,
nor to any particular form of apparatus, but what we claim is the combination
of the purified volatile oils or "napthas" as above enumerated, with resin of
commerce for the formation of a "new paint oil" substantially as above
described.
In witness whereof, we, the said William Rhodes and Henry Napier.
have heretofore set our hands and seals, the Thirtieth day of July, in
the year of our Lord One thousand eight hundred and fifty-eight.
Signed, sealed, and delivered in the
presence of
