Year: 1863

page_text: LETTERS PATENT to John Travis, of Luzley Brook, in the Township of
Royton, in the County of Lancaster, Gentleman, for the Invention of
"AN IMPROVED METHOD OF PREVENTING THE INCRUSTATION OF EARTHY MATTER
IN STEAM ROLES GENERATORS AND THEY WONOMIERDS"
PROVISIONAL SPECIFICATION left by the said John Travis at the Office
of the Commissioners of Patents, with his Petition, on the 3rd Junc
1868.
I, JOHN TRAVIS, of Luzley Brook, in the Township of Royton, in the County
of Lancaster, Gentleman, do hereby declare the nature of the said Invention
for "AN IMPROVED METHOD OF PREVENTING THE INCRUSTATION OF EARTHY MATTER
IN STEAM BOILERS, STEAM GENERATORS, AND FUEL ECONOMIZERS," to be as follows:-
I put into the boiler at the man-hole, or into a tank from whence the boiler,
steam generator, or fuel economizer is supplied with water, carrageen or Irish
moss, or silicate of soda, or arseniate of soda, or phosphate of soda. Either of
these substances, singly or compounded, will prevent incrustation. The earthy
matter held in particles or in solution by the above-named substances settles
to the bottom of the boiler when the water is let off, and is swept or washed
away. As the quality of water varies very much in different districts, some
waters having more and others less impurities, and also as the character or nature
of the impurities differ in different waters used, the quantity of the above-named
substances must be determined by experiment; but as a criterion or guide to
the use of the above Invention in waters of a middling or most prevaling
quality from six to eight pounds weight of carrageen or Irish moss per week
to a boiler of from 40 to 50 horse-power, and the like weight per week of each

page_text: of the other named substances when used separately, or when compounded of
two or more or all of the substances named. Where the water is charged
of the other named substances when used separately, or when compounded of
two or more or all of the substances named. Where the water is charged
with a greater amount of impurity an additional quantity must be added, and
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Travis in the Great Seal Patent Office on the 2nd
December 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
TRAVIS, of Luzley Brook, in the Township of Royton, in the County of
Lancaster, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of June, in the year of our Lord Oue
thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her beirs and successors, give and grant unto me,
the said John Travis, Her special license that I, the said John Travis, my
executors, administrators, and assigns, or such others as I, the said John Travis,
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 METHOD OF PREVENTING THE
INCRUSTATION OF EARTHY MATTER IN STEAM BOILERS, STEAM GENERATORS, AND
FUEL ECONOMIZERS," upon the condition (amongst others) that I, the said John
Travis, 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 John Travis, 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,
that is to say:-
I put into the boiler at the man-hole, or into a tank from whence the boiler,
steam generator, or fuel economizer is supplied with water, carrageen or Irish
moss, sillicate of soda, or arseniate of soda, or phosphate of soda; each of these

page_text: substances, singly or compounded, will prevent incrustation. The earthy
matter held in particles becomes a precipitate, settles to the bottom of the
boiler when the boiler is let off, and is swept or washed away. As the
quality of waters varies very much in different districts, some waters having
more and others less impurities, and also as the character or nature of the
impurities differ in different waters, the quantity of the above-named substances
to be used must be determined by experiment; but as a criterion or guide to
the use of this Invention, for waters of middling or most prevailing quality,
from six to eight pounds in weight of carrageen or Irish moss per week to a
boiler of about forty horses power will suffice; the like weight of any of the
other substances when used separately or compounded of two or more or of
all the substances herein named. If the water be charged with a greater
amount of impurity an additional quantity must be added, and when there is
less impurity a smaller quantity will do. But in the use of the above-named
substances I give the preference to and recommend in most cases the sole
use of carrageen or Irish moss, especially in new boilers, and in old ones
where the incrustation has been cleared off.
of
Having thus fully described the nature of my said Invention, and the
manner in which the same is to be performed, I would have it understood that
I do not confine myself to the precise details so long as the peculiar character
my Invention be retained; neither do I claim the separate use of silicate of
soda, or arseniate of soda, or phosphate of soda; but I do claim the use of
carrageen or Irish moss, or the sea weed possessing the like properties, by
whatsoever different name it may be called, either in its natural state, or
ground, or in decoction, with or without silicate of soda, arseniate of soda, or
phosphate of soda, for the purposes herein set forth and described.
In witness whereof, I, the said John Travis, have hereunto set my
hand and seal, this Twenty-eighth day of November, in the year of
our Lord One thousand eight hundred and sixty-three.
Signed, sealed, and delivered by the
within-named John Travis, in
the presence of
JOHN H. TRAVIS, Patent Agent,
Royton.
JOHN TRAVIS. (L.S.)
