THE MANUFACTURE OF À NEW PRODUCT FROM PEAT AND PEAT TAR
Year: 1863

page_text: LETTERS PATENT to Louis Rudolph Bodmer, of 2, Thavies Inn, Holborn,
in the City of London, for the Invention of "THE MANUFACTURE OF À
NEW PRODUCT FROM PEAT AND PEAT TAR."-A communication from abroad
by Edmund Hess, of the Ostracher Ried Company, Pfrungen, in the
Kingdom of Wurtemberg.
Sealed the 12th January 1864, and dated the 16th July 1863.
PROVISIONAL SPECIFICATION left by the said Louis Rudolph Bodmer at
the Office of the Commissioners of Patents, with his Petition, on the
16th July 1863.
I, LOUIS RUDOLPH' BOdmer, of 2; Thavies Inn, Holborn, in the City of
London, do hereby declare the nature of the said Invention for "THE MANU-
FACTURE OF A NEW PRODUCT FROM PEAT AND PEAT TAB," (a communication from
abroad by Edmund Hess, of the Ostracher Ried Company, Pfrungen, in the
Kingdom of Wurtemberg,) to be as follows:--
The peat tar obtained by the distillation of the ordinary peat, or of the
compressed and condensed or solidified peat, may by repeated distillation and
certain chemical processes be transformed into a variety of sub-products, such
as photogene, paraffine, naphtha, and others. Instead, however, of forming any
of these sub-products, this Invention has for its object the manufacture or
production from peat and peat tar of lampblack, for which purpose the crude
oil obtained by simple distillation of the peat tar is used in preference. The
lampblack may be produced in a vaulted chamber, along one side of which a

page_text: pipe or tube is placed, and which is supplied with the crude oil from without
the chamber. This pipe is fitted with a number of holes or small tubes, into
which wicks are inserted, and which in this manner form a system of lamps.
The admission of air is regulated by means of dampers or sliding valves or
gratings placed or fitted into the wall along the line of lamps, and in order to
increase the production of soot or lampblack the admission of air is reduced to
a minimum. The soot or lampblack adheres to the walls and arched roof of
the vault, and is from time to time removed or brushed off and collected.
The hot air from the lamps is carried away by suitable flues and chimney.
The lampblack obtained from peat, peat tar, and its oils is an entirely new
product and far superior in quality to the lampblack hitherto made from coal
tar.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Louis Rudolph Bodmer in the Great Seal Patent Office
on the 16th January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Louis
RUDOLPH BODMER, of 2, Thavies Inn, Holborn in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of July, 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
Louis Rudolph Bodmer, Her special licence that I, the said Louis Rudolph
Bodmer, my executors, administrators, and assigns, or such others as I, the said
Louis Rudolph Bodmer, 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." THE
MANUFACTURE OF A NEW PRODUCT FROM PEAT AND PEAT TAR," (a communication
from abroad by Edmund Hess, of the Ostracher Ried Company, Pfrungen, in
the Kingdom of Wurtemberg, upon the condition (amongst others) that I, the
said Louis Rudolph Bodmer, 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

page_text: 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 Louis Rudolph Bodmer, 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 :-
The peat tar obtained by the distillation of the ordinary peat, or of the
condensed or solidified peat, may, by repeated distillation and certain other
processes be transformed into a variety of sub-products, such as photogen,
parafin, naphtha, and others. Instead, however, of forming any of these
products, this Invention has for its object the manufacture or production from
peat, from the oils obtained from peat, from peat tar and peat asphaltum, of
the substance known as lampblack, and the crude oil obtained by the simple
distillation of peat tar is used in preference for this purpose.
This lampblack
may be produced in a vaulted chamber, along the side or sides of which pipes
are placed, which pipes can be supplied with the crude oil from without the
vaulted chamber. The pipes are fitted with a number of small holes or tubes, into
which wicks are inserted, and which form in this manner a system of lamps.
The admission of air is so regulated by means of dampers, valves, or gratings,
fitted into the walls of the chamber, as to produce an imperfect combustion,
and at the same time the largest possible amount of soot.
For producing
lampblack from asphaltum obtained from peat tar a vaulted chamber similar
to the one described may be used, the pipes forming the system of lamps being
omitted. This vaulted chamber is connected with a flue, into which flue when
heated to a red heat the asphaltum is thrown in lumps. The asphaltum will
suddenly ignite, and, owing to the limited admission of air, produce large
quantities of soot or lampblack, while the heat from the combustion is sufficient
for keeping up the temperature of the flue. The lampblack thus produced is,
however, inferior to that made from peat tar oil.
Various methods employed for making lampblack from coal tar, asphaltum,
resinous pine, and other matter, may, with trifling alterations, be used for the
production of lampblack from peat and its products..
The manufacture of lampblack from peat and its products of distillation is
entirely new, and this lampblack is far superior to that made from coal, coal
tar oil, asphaltum, and such matter.
Having now described the nature of the said Invention which has been
communicated to me, I wish it to be understood that I do not claim nor restrict
myself to the use of any particular apparatus or method of operating; but
what I do claim as the Invention to be secured to me by the herein-before in

page_text: part recited Letters Patent is, the production and:.manufacture' of lampblack
from peat, and from the tar, oils, and asphaltum obtained in its distillation.
In witness whereof, I, the said Louis Rudolph Bodmer, have hereunto
set my hand and seal, this Sixteenth day of January, in the year of
our Lord One thousand eight hundred and sixty-four.
