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-
PROVED MEANS OF PREVENTING INCRUSTATIONS IN STEAM BOILERS."-A com-
munication from abroad by Louis Serbat, of Saint Saulve, France.
Sealed the 7th February 1860, and dated the 8th August 1859.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 8th August 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
Invention for "IMPROVED MEANS OF PREVENTING INCRUSTATIONS IN STEAM
BOILERS," (communicated to me from abroad by Louis Serbat, of Saint Saulve,
France,) to be as follows:-
This Invention consists in employing leather as a means of preventing
incrustations in steam boilers. The leather may either be enclosed or not in
wire gauze, and is simply immersed in the water contained in the boiler in
suitable quantity. Greater effect is produced if the leather is previously
submitted to washing in a bath of weak acid, and thereby deprived of foreign
matters. Any leather will answer for the purpose of the Invention; but the
Inventor prefers to employ old and waste leather as being more economical.

on the 8th February 1860.
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 Eighth day of August, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third 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 "IMPROVED MEANS OF PREVENTING INCRUSTATIONS IN STEAM BOILERS,"
(communicated to me from abroad by Louis Serbat, of Saint Saulve, France,)
upon the condition (amongst others) that I, the said Richard Archibald
Brooman, 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 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, that is to say :-
This Invention consists in employing leather as a means of preventing
incrustations in steam boilers. The leather may either be enclosed or not in
wire gauze, and is simply immersed in the water contained in the boiler in
suitable quantity. Greater effect is produced if the leather is previously
submitted to washing in a bath of weak acid, and thereby deprived of foreign
matters. Any leather will answer for the purpose of the Invention; but the
Inventor prefers to employ old and waste leather as being more economical.
The quantity of leather which it is necessary to employ varies according to

page_text: the amount of saline matter in the water; but a pound or a pound and a half
to each horse-power of the engine will generally be found sufficient.
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 the prevention
of incrustations in steam boilers by immersing in the water contained therein
leather enclosed or not in wire gauge, as herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Eighth day of February, One thousand
eight hundred and sixty.
