Sealed the 3rd June 1864, and dated the 8th December 1863.
PROVISIONAL SPECIFICATION left by the said Henry Benson James
at the Office of the Commissioners of Patents, with his Petition, on the
8th December 1863.
I, HENRY BENSON JAMES, of Fish Street Hill, in the City of London
Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED COMPOSITION FOR COVERING STEAM BOILERS AND PIPES AND OTHER
SURFACES," to be as follows:-
The ingredients which enter into my improved composition for covering
surfaces exposed to great heat, and others, are the following, but the pro-
portions herein-after given are only approximative and necessarily vary to suit
particular circumstances, soot, coal dust, ivory black or lamp black, about
4 cwt.; varnish, gums, mastic or any other binding ingredient which I may
prefer (with the exception of glue), about 5 gallons; cow dung or any animal
excrement, about 5 cwt.; fullers' earth, chalk, or other earthy substances,
about 4 cwt.; Roman or other cement, about 1 cwt.; alkali, about a cwt.;
refuse railway grease (principally for cold surfaces), about 1 cwt., and water
sufficient to bring the matters to a proper consistency.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BENSON JAMES, of Fish Street Hill, in the City of London, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of December, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Benson James, Her special licence that I, the said Henry
Benson James, my executors, administrators, and assigns, or such others as I,
the said Henry Benson James, 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 "AN
IMPROVED COMPOSITION FOR COVERING STEAM BOLLERS AND PIPES AND
SURFACES," upon the condition (amongst others) that I, the said Henry
Benson James, 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.
OTHER
NOW KNOW YE, that I, the said Henry Benson James, 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 :-
My Invention consists in an improved composition for covering surfaces
which are exposed to the action of great heat, or, with slight modification, for
covering or insulating cold surfaces.
The ingredients which enter into or compose the mass, which, after
manufacture or treatment, becomes my improved composition, are as follows:-

page_text: I take of ivory black or lamp black four hundred weight (say 448 lbs.) of
varnish, gums, mastic, or other resinous or binding ingredient (it being for this
purpose I use the varnish), sixteen pounds weight (16 lbs.), which, when dis-
solved to the proper liquidity, will produce five gallons, (I except from these
resinous or sticky substances the article known as glue, of which I make no
use); of cow dung, or other animal excrement, five hundred weight (say
560 lbs.); of fullers' earth, chalk, or similar dry earthy substance, also five
hundred weight (560 lbs.); Roman, Portland, or other dry powder cement,
half a hundred weight (56 lbs.); (alkali (ordinary alkali), half a hundred
weight (56 lbs.); water sufficient to bring the matters forming the mass to a
proper consistency.
The above-named ingredients form, when mixed and ground, my composi-
tion for covering steam boilers, pipes, and surfaces exposed to great heat; but
for cold surfaces, such as roofing, or when my composition is used as an insu-
lator, say between metal and metal, such as an iron ship's side and the metal
sheathing employed, I add to the before-recited ingredients, and while in the
mass, and to form part thereof, one hundred weight (say 112 lbs.) of refuse
railway grease, or other cheap refuse grease. I pass this mass through an
ordinary mill and grind until the ingredients mix or combine and are of the
consistency required.
Having now described the nature of my said Invention, and the means by
which I carry it into practical effect, I would have it distinctly understood
that although the proportions of ingredients herein-before directed to be
used in making my composition have been found in practice to give the
result desired, yet, from the difference of quality or from other causes, it may
be requisite to vary or modify the arrangement of the quantities, and I reserve
to myself the right so to vary or modify the said quantities to suit the circum-
stances of particular cases, so long as I do not essentially depart from the com-
bination herein-before described.
In witness whereof, I, the said Henry Benson James, have hereunto set
my hand and seal, this Fourth day of June, in the year of our Lord
One thousand eight hundred and sixty-four.
H. B. JAMES. (L.S.)
