IM- PROVEMENTS IN HEATING
Year: 1859

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, E.C., Patent Agent, for the Invention of "IM-
PROVEMENTS IN HEATING."-A communication from abroad by Stanislas
Labobo of Paris
Sealed the 15th November 1859, and dated the 18th May 1859.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 18th May 1859.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, E.C., Patent Agent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN HEATING," (communicated to me from abroad by
Stanislas Lebobe, of Paris,) to be as follows:-
This Invention consists in obtaining and utilizing for heating purposes the
hydrogen contained in steam, particularly in waste steam from boilers and
engines. I lead the waste steam through pipes or chambers heated to redness,
and pass the gases thereby generated through tar or other agent which will
absorb the oxygen, while I collect, the pure hydrogen and mix it with other
.combustible material, or burn it alone.

by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 18th November 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, E.C.,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of May, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Richard Archibald Brooman, Her special licence that I, the
said Richard Archibald Brooman, my executors, administrators, and assigns,
or such others as I, the said Richard Archibald Brooman, 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 HEATING," (a communication
from abroad by Stanislas Lebobe, of Paris,) upon the condition (amongst
others) that I, the said Richard Archibald Brooman, my executors or admi-
nistrators, 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 Richard Archibald Brooman, 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, reference being had to the Drawings hereunto
annexed, that is to say:-
This Invention consists in obtaining and utilizing for heating purposes the
bydrogen contained in steam, particularly in waste steam from boilers and
engines. The Inventor leads the waste steam through pipes or chambers
heated to redness, and passes the gases thereby generated through tar or
other agents which will absorb the oxygen, while the pure hydrogen is collected
and mixed with other combustible material, or burnt alone.
Although this Invention is applicable to all kinds of apparatuses at present

page_text: constructed for the generation of steam, the Inventor has found it particularly
advantageous when applied as illustrated in the accompanying Drawing,
which is a sectional elevation of the apparatus. A is a water reservoir; B is
the suction pipe of a feed pump, which is placed at a sufficient height to carry
off pure water only; C is a discharge pipe from a safety valve placed at the upper
part of the reservoir; D is a pipe through which the water from the pump
is forced into a tubular steam-generator E. This tubular generator may be
replaced by any other apparatus presenting a large heating surface compared
with its capacity. F is a pipe for the passage of steam from the generator to
the engine; G is a steam pipe leading the waste steam from the engine to be
superheated; H is the superheating apparatus; I is a pipe leading from this
apparatus H into the absorbing vessel J, which contains tar, or any other
material capable of absorbing the oxygen; K is a pipe for conducting the
pure hydrogen thence into a burner, with jets L, where it is burnt. The
arrangement of this burner is regulated by the size and construction of the
generating and superheating apparatuses. P is a passage by which the
products of combustion are carried up into the dome Q, where they mix with
the air, and fall as water into the reservoir A; M is a receptacle for the tar.
On cooling, the tar parts with the oxygen, and may be used over again. N is
a tap for drawing off the contents of the absorbing vessel.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the method of obtaining and utilizing for heating purposes the hydrogen
contained in steam, particularly in waste steam from boilers and engines as
herein-before described.
And, second, the construction of apparatus for the purpose, as herein-before
described and illustrated in the accompanying Drawing.
In witness whereof, I, the said Richard Archibald Brooman, have
hereunto set my hand and seal, this Eighteenth day of November, One
thousand eight hundred and fifty-nine.
R. A. BROOMAN. (L.S.)
