AN IMPROVED ANTI-ACID OIL
Year: 1866

page_text: LETTERS PATENT to William Barrington Brown, of the City of Man-
chester, in the County of Lancaster, for the Invention of "AN IMPROVED
ANTI-ACID OIL."
Sealed the 11th December 1866, and dated the 16th June 1866.
PROVISIONAL SPECIFICATION left by the said William Barrington Brown
at the Office of the Commissioners of Patents, with his Petition, on
the 16th June 1866.
I, WILLIAM BARRINGTON BROWN, of the City of Manchester, in the County
of Lancaster, do hereby declare the nature of the said Invention for "AN
IMPROVED ANTI-ACID OIL," to be as follows:-
I use seaweed as the principal element in preparing my oil, and in
preference to all other seaweed the chondrus crispus and chondrus mam-
mulosus or carrageen moss; I also use a portion of olive or other oil to
facilitate the process of preparation; also condensed or distilled steam strongly
impregnated with the above-named seaweed in conjunction with soda, chloride
of soda, or muriate of soda, in different proportions, according to the purposes
for which the anti-acid oil is to be used.
I put the seaweed into a strong iron cylinder that will bear a pressure of
from fifty to sixty pounds on the square inch; say, if the cylinder be capable

page_text: of holding four gallons I put into it four pounds of carrageen moss, and add
four pounds of soda, or chloride of soda, or muriate of soda, or potash;
having made the cylinder perfectly secure I introduce steam at a high
pressure, say from 300° to 400° Fahrenheit, by means of a pipe from an
adjoining boiler, the water of which is strongly impregnated with seaweed,
and keep the whole under this heat for about ten hours, when the cylinder
will be full of this condensed steam mixed with the other materials, and the
oil separated from the carrageen moss; I then turn off the steam and allow
the cylinder to cool. In opening the cylinder care is necessary to prevent the
effects of the high pressure; then I empty the contents into a vessel, and
introduce a small portion of carbonate of lime or zinc, or any other well-
known chemical that will produce the same effect to hasten the precipitation
of the fibrous matter mixed with the liquor; I then decant off the surface
liquor, and to every gallon add about three gills of oil; I then boil the liquor
slowly in a pan or vat for about six hours, or so long as is sufficient to drive
off whatever aqueous particles that may be mixed with the oil, keeping, how-
ever, the whole in a state of agitation during this process.
The quantities of the above-named materials must be determined by the
quality of the seaweed used, which can easily be ascertained during the
-manipulation.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Barrington Brown in the Great Seal Patent Office
on the 14th December 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BARRINGTON BROWN, of the City of Manchester, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of June, in the year of our Lord
"One thousand eight hundred and sixty-six, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
'me, the said William Barrington Brown, Her special license that I, the said
William Barrington Brown, my executors, administrators, and assigns, or such
others as I, the said William Barrington Brown, 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
Hawfully might make, use, exercise, and vend, within the United Kingdom

page_text: of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "AN IMPROVED ANTI-ACID OIL," upon the condition (amongst
others) that I, the said William Barrington Brown, my executors or
administrators, by an instrument in writing under my, or their, or one
of their 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 I, the said William Barrington Brown, 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) :-
I use seaweed as the principal element in preparing my oil, and in
preference to all other seaweed, the chondrus crispus and chondrus mam-
milossus or carrageen moss; I also use a portion of olive or other oil to
facilitate the process of preparation; also condensed or distilled steam strongly
impregnated with the above-named seaweed in conjunction with soda, chloride
of soda, or muriate of soda, in different proportions, according to the purposes
for which the anti-acid oil is to be used.
I put the seaweed into a strong iron cylinder that will bear a pressure of
from fifty to sixty pounds on the square inch; say, if the cylinder be capable
of holding four gallons I put into it four pounds of carrageen moss, and add
four pounds of soda, or chloride of soda, or muinte of soda, or potash; having
made the cylinder perfectly secure I introduce steam at a high pressure, say
from 300° to 400° (or more) Fahrenheit, by means of a pipe from an adjoining
boiler, the water of which is strongly impregnated with seaweed, and keep
the whole under the heat for about ten hours, when the cylinder will be full
of this condensed steam mixed with the other materials, and the oil separated
from the carrageen moss; I then turn off the steam, and allow the cylinder
to cool. In opening the cylinder care is necessary to prevent the effects of
the high pressure. Then I empty the contents into a vessel, and introduce a
small portion of carbonate of lime or zinc, or any other well-known chemical
that will produce the same effect to hasten the precipitation of the fibrous
matter mixed with the liquor; I then decant off the surface liquor, and to
every gallon add about three gills of oil; I then boil the liquor slowly in a
pan or vat for about six hours, or so long as is sufficient to drive off' whatever
aqueous particles that may still be mixed with the oil, keeping, however, the
whole in a state of agitation during this
For the sake of economy I
process.

page_text: advise that the residuum be collected and dried, then ground in a crushing
machine, and afterwards subjected to hydraulic pressure.
The quantities of the above-named materials must be determined by the
quality of the seaweed used, which can easily be ascertained during the
manipulation.
Having thus fully described the nature of my said Invention, and the
manner in which the same is to be performed, I would have it understood
that I do not confine myself to the precise details so long as the peculiar
character of my Invention be retained; neither do I claim the separate or
joint use of soda, chloride of soda, muriate of soda, or potash; but I do
claim the use of seaweed, especially of carrageen moss, with or without
soda, chloride of soda, muriate of soda, or potash, herein set forth and
described.
In witness whereof, I, the said William Barrington Brown, have here-
unto set my hand and seal, this Thirteenth day of December, in
the year of our Lord One thousand eight hundred and sixty-six.
WILLIAM BARRINGTON BROWN. (L.S.)
Signed, sealed, and delivered by the
within-named William Barrington
Brown, in the presence of
