Kettenhofweg, Frankfort-on-the-Maine, for the Invention of "IMPROVE-
"
PROVISIONAL SPECIFICATION left by the said Jean François Nicolas
Biesman Simons at the Office of the Commissioners of Patents, with.
bis Petition, on the 29th May 1867.
I, JEAN FRANÇOIS NICOLAS BIESMAN SIMONS, of No. 23, Kettenhofweg,
Frankfort-on-the-Maine, do hereby declare the nature of the said Invention.
for "IMPROVEMENTS IN PREVENTING THE INCRUSTATION OF STEAM BOILERS," to.
be as follows:-
This Invention has for its object improvements in preventing the incrustation
of steam boilers. For this purpose I grind charcoal, by preference light and.
porous wood charcoal, to a fine powder, and I mould it by heavy pressure, by
preference hydraulic pressure, into discs or other forms. exposing a large-
surface. The pieces of moulded charcoal so formed I introduce into the
boiler and allow them to float on the surface of the water, so that the
incrustation may form on them in place of upon the plates of the boiler, and

page_text: this I find to take place in practice. When the discs or pieces of moulded
charcoal have become thickly incrusted they are taken out and others
substituted.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean François Nicolas Biesman Simons in the Great Seal
Patent Office on the 25th November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
FRANÇOIS NICOLAS BIESMAN SIMONS, of No. 23, Kettenhofweg, Frankfort-on-
the-Maine, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of May, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jean François Nicolas Biesman Simons, Her special licence that I,
the said Jean François Nicolas Biesman Simons, my executors, administrators,
and assigns, or such others as I, the said Jean François Nicolas Biesman
Simons, 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 "IMPROVEMENTS IN
PREVENTING THE INCRUSTATION OF STEAM BOILERS," upon the condition (amongst
others) that I, the said Jean François Nicolas Biesman Simons, 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 Jean François Nicolas Biesman Simons,
do hereby declare the nature of the said Invention, and in what manner the.
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
.
This Invention has for its object improvements in preventing the in-
crustation of steam boilers. For this purpose I grind charcoal, by preference
the charcoal of a fine grained light and porous wood, to a fine powder, I mix.

page_text: I
it with a small quantity of agglutinating material, such as tar, and I mould it
by heavy pressure, by preference bydraulic pressure, into discs or other forms
exposing a large surface. The disc or other moulded forms I expose in a
close vessel to a heat sufficient to decompose the tar or other agglutinating
matter, and then when only a pure carbon remains they are ready for use.
introduce them into the boiler and allow them to float on the surface of the
water, so that as usually occurs the incrustation may form on them in place
of upon the plates of the boiler. In some cases, however, the impurities of
the water in place of forming an incrustation on the discs or moulded pieces
of carbon are precipitated in a pulverulent state, and in this state are readily
blown out of the boiler. In either case the plates of the boiler are protected
from incrustation; when the discs or moulded pieces of carbon have become
thickly incrusted they are taken out and others substituted.
In witness whereof, I, the said Jean François Nicolas Biesman
Simons, have hereunto set my hand and seal, this Eighteenth day of
November, in the year of our Lord One thousand eight hundred and
sixty-seven.
