in the City of London, Naval Engineer, for the Invention of "AN IM-
PROVED COMPOSITION FOR VESSELS, FURNACES, AND OTHER APPARATUS TO BE
EXPOSED TO THE OPERATION OF GREAT HEAT AND THE EFFECT OF FLUXES AND
THE LIKE."
Sealed the 22nd February 1861, and dated the 27th September 1860.
PROVISIONAL SPECIFICATION left by the said Joseph Jepson Oddy
Taylor at the Office of the Commissioners of Patents, with his Petition,
on the 27th September 1860.
I, JOSEPH JEPSON ODDY TAYLOR, of No. 12, Mark Lane, in the City of
London, Naval Engineer, do hereby declare the nature of the said Invention
for "AN IMPROVED COMPOSITION FOR VESSELS, FURNACES, AND OTHER APPARATUS TO
BE EXPOSED TO THE OPERATION OF GREAT HEAT AND THE EFFECT OF FLUXES AND THE
LIKE," to be as follows:-
My Invention consists in the employment of the following materials; first,
of about one-fourth part of burnt or worn out crucibles or old pots; secondly,
of about one-fourth part of Derby blue clay in its raw state, but to be
thoroughly and gradually dried; thirdly, of about one-fourth part of kaolin
mixed with lampblack to the colour of lead; and lastly, of about one-fourth
part of Derby blue clay calcined by putting it into a hot crucible, each to be

page_text: reduced to a dry powder and mixed up together, damp, to the consistency of
pot-makers clay, then to be applied in a moist state as a lining, as well as
made into fire-bricks for building and lining furnaces, cupolas, stoves, and
other apparatus, and into crucibles, pots, and vessels of every description to
be exposed to the operation of great heat, and the effect of fluxes and the like,
then to be dried in the same manner as is generally practised until fit
for use
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Jepson Oddy Taylor in the Great Seal Patent
Office on the 23rd March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
JEPSON ODDY TAYLOR, of No. 12, Mark Lane, in the City of London, Naval
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of September, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Joseph Jepson Oddy Taylor, Her special licence that I, the said
Joseph Jepson Oddy Taylor, my executors, administrators, and assigns,
or such others as I, the said Joseph Jepson Oddy Taylor, my execu-
tors, 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 "AN IMPROVED COMPOSITION FOR
VESSELS, FURNACES, AND OTHER APPARATUS TO BE EXPOSED TO THE OPERATION
OF GREAT HEAT AND THE EFFECT OF FLUXES AND THE LIKE," upon the condition
(amongst others) that I, the said Joseph Jepson Oddy Taylor, 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 per-
formed, 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 Jepson Oddy Taylor, do 3
hereby declare the nature of my said Invention, and in what manner

page_text: the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
:
My Invention consists in the employment of the following materials, and
which in and by my Provisional Specification left at the Office of the Commis-
sioners of Patents on the 27th day of September, 1860, I have described as
about one-fourth part of burnt or worn out crucibles or old pots, about one-
fourth part of Derby blue clay in its raw state, but to be thoroughly and
gradually dried, about one-fourth part of kaolin mixed with lampblack to the
colour of lead, and about one-fourth part of Derby blue clay calcined by
putting it into a hot crucible, each to be reduced to a dry powder and mixed
up together, damp, to the consistency of pot makers' clay, then to be applied
in a moist state as a lining, as well as made into fire-bricks for building and
lining furnaces, cupolas, stoves, and other apparatus, and into crucibles, pots,
and vessels of every description to be exposed to the operation of great heat,
and the effect of fluxes and the like, then to be dried in the same manner as is
generally practised until fit for use.
I have since the filing of such Provisional Specification ascertained by
experience that the before-mentioned materials forming the composition must
be varied in some degree in their proportions according to the peculiar pur-
poses they are intended to answer, and by way of illustrating the application
of the admixture for the making of crucibles or pots, I explain that one
hundredweight, two quarters, and twelve pounds of clay, one part Derby and
three parts of Stannington or other suitable clays mixed with two quarters
and nineteen pounds of burnt or worn out crucibles or pots with no glaze upon
them, ten pounds and eight ounces of kaolin carefully picked over, one pound
and eight ounces of lampblack, and one quarter and seventeen pounds of
calcined Derby clay, with eighteen pounds of ground coke, not too fine, the five
last-mentioned ingredients to be sifted through a sieve of eight or ten meshes to
the inch, the dust not to be used, with six pounds additional coke to be trod
in or otherwise mixed in the process of manufacture are sufficient to make
twelve crucibles or pots, of twenty-eight pounds each. The clays to be dried,
and afterwards fell, similar to slaking of lime, so as to render them suitable
for treading by the human feet, or otherwise, until they acquire the desired
ductility or pliancy. The crucibles to be thoroughiy dried and annealed in
the furnace before brought into use.
The bricks to be made of the same
materials, with such variation in their proportions as experience and practice
may suggest, and made into any size or shape required. The materials
before-mentioned may be made into a state similar to mortar, and applied
in a moist state as a lining to furnaces, cupolas, stoves, and other apparatus.

page_text: And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim for my Invention
of an improved composition for vessels, furnaces, and other apparatus to be
exposed to the operation of great heat and the effect of fluxes and the like;
the employment of the before-mentioned materials to be applied in a moist
state as a lining, as well as made into fire-bricks for building, and lining
furnaces, cupolas, stoves, and other apparatus, and into crucibles, pots, and
vessels of every description to be exposed to the operation of great heat and the
effect of fluxes and the like.
In witness whereof, I, the said Joseph Jepson Oddy Taylor, have here-
unto set my hand and seal, this Twenty-first day of March, in the year
of our Lord One thousand eight hundred and sixty-one.
J. J. O. TAYLOR. (L.S.)
