Year: 1862

page_text: LETTERS PATENT to Christopher Hill, of Ferryside, Kidwelly, in the
County of Carmarthen, Coal Agent, for the Invention of "IMPROVEMENTS
N THE MANTRA COULD OR LUBRICATE
TING COMPOUNDS"
PROVISIONAL SPECIFICATION left by the said Christopher Hill at the
Office of the Commissioners of Patents, with his Petition, on the 14th
January 1862.
I, CHRISTOPHER HILL, of Ferryside, Kidwelly, in the County of Carmar-
then, Coal Agent, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF LUBRICATING COMPOUNDS," to be as
follows:-
In
This Invention has for its object improvements in the manufacture of
lubricating compounds, and consists, firstly, in combining for this purpose
Carragea moss with fatty matters, or with soap, or with both soap and fatty
matters, also the combining steatite, or steatite together with Carragea moss,
with fatty matters, or with soap, or with both soap and fatty matters.
order to make a thick grease, I prepare a pulp by boiling down Carragea
moss, and I sometimes add to this a small quantity of flour. I then take 14
parts of this, into which I dissolve one part of ordinary yellow soap, 1 parts of
tallow, or 1 part of candle composite, 1 part of palm oil, a part of lard, or I
substitute another part of tallow, of a part of finely pulverized steatite,
and 1 part of soda, I sometimes substitute borax. When all are thoroughly

page_text: dissolved and mixed over a steady heat, the operation is completed by running
it through a fine strainer, and cooling down, stirring gradually as it cools.
In order to make a liquid grease, which I call "white oil," I prepare a thin
pulp from the Carragea moss; of this I take 10 parts, and add 8 parts of lard
oil, or 4 parts of lard oil, and 4 parts of rape or olive oil, of finely pulverized
steatite, of liquid caustic potash, at 10° Beaumé. I sometimes add a part
of soft soap; I warm'all these up to a scalding temperature, stirring well during
the time, until well mixed, when. I cool down, stirring during the time.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Christopher Hill in the Great Seal Patent Office on the 11th
July 1862.

statement thereof, that is to say :-

page_text: First, to make a thick grease, I prepare a pulp or jelly by boiling down
in water Carragea moss, so as to obtain a jelly or pulp of a good consistency
(I sometimes add to this a small quantity about one part in 30 parts of flour.)
I then take 14 parts of this jelly, into which I dissolve 1 part of common
yellow soap, 1 parts of tallow, or 1 part of candle composite, one part of
palm oil, a part of lard, or I substitute another half part of tallow, of
a part of finely pulverized steatite, and 1 part of common soda, I sometimes
substitute borax; when all are thoroughly dissolved and well mixed over
a steady heat, I run it through a fine sieve, and cool down, stirring gradually
as it cools.
Second, to make a liquid grease, I prepare a thin pulp or jelly from
the same description of moss, and in the same manner; of this I take 10
parts, and add 8 parts of lard oil, or 4 parts of lard oil and 4 parts of rape
or olive oil, th of a part of finely pulverized steatite, part of caustic
potash, at the specific gravity of 10° Beaumé. I sometimes add half a part
of soft soap. I warm all these up to a scalding temperature, stirring well during
the time until all is well mixed, when I strain and cool down, stirring as it
.cools.
In witness whereof, I, the said Christopher Hill, have hereunto set my
hand and seal, this Ninth day of July, in the year of our Lord One
thousand eight hundred and sixty-two.
Witness,
