Year: 1864

page_text: LETTERS PATENT to Joseph Hamilton Beattie, of No. 11, Dowgate Hill,
London, Civil Engineer, for the Invention of "IMPROVEMENTS IN THE
MEANS OF PREVENTING THE FORMATION OF AND IN THE REMOVAL OF INCRUS-
TATIONS OR DEPOSITS FROM STEAM ENGINE BOILERS.-A communication from
abroad by Joseph Marks, of the City of Montreal, Canada.
Sealed the 13th December 1864, and dated the 20th June 1864.
PROVISIONAL SPECIFICATION left by the said Joseph Hamilton Beattie
at the Office of the Commissioners of Patents, with his Petition,
on the 20th June 1864.
I, JOSEPH HAMILTON BEATTIE, of No. 11, Dowgate Hill, London, Civil
Engineer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MEANS OF PREVENTING THE FORMATION OF AND IN THE REMOVAL OF INCRUS--
TATIONS OR DEPOSITS PROM STEAM ENGINE BOILERS," to be as follows:-
A new and useful anti-incrustation powder for the removal of deposits off
the internal surfaces of steam-generating boilers without injury to the metallic
substance thereof, of which the following is a full and exact description, and
consists of the following proportionate combination of ingredients, each by
weight thus:-Muriatic acid twenty-five hundredths; ammonia, twenty-five.
hundredths; the pure salt of the native sugar cane, thirty-three hundredths,
mixed with mahogany dust, seventeen hundredths.
Having thus stated of what my Invention consists, I will now explain the
method of manufacturing the same.

page_text: First mix muriatic acid and ammonia, thoroughly pulverize the salt obtained,
then add the pure salt of the native sugar cane also pulverized, the whole to
be properly mixed with the mahogany dust.
The advantages of the use of the above combination are that the substance
used penetrates through the deposit to the metallic substance of the boiler and
will not penetrate the metallic substance thereof. It also prevents any
foaming or priming in the boiler during the process of removing the.deposit
therefrom, and any slight leakage that may be caused by the removal of the
deposit will be immediately stopped.
The mode of application for the removal of the deposit is as follows:-
When the deposit in the boiler is very thick introduce one and a half pounds
of the powder for an ordinary sized locomotive boiler, allowing the boiler to
work twelve hours, then have it blown off and washed out, then add one pound
of the powder in the feed-water tank of the boiler for twelve successive days,
blowing the boiler off every second day, washing it out every third day, so as
to clean out the displaced deposit. This will be quite sufficient to effectually
clean any boiler of the deposit, and in order to prevent any further .accumu-
lation of the deposit within the boiler it would be well to use one half pound
per diem in the feed water used.
Having stated in what my Invention consists and the mode by which it is,
to be carried into operation, I may state that I find the proportion of ingre-
dients given above are the best for use in the most usual cases, but that the
proportions may be varied to suit special circumstances, and that what I claim
is, the use of the various combinations of ingredients stated above for the
purpose mentioned, and that I do not claim the use of the ingredients
separately.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Hamilton Beattie in the Great Seal Patent Office on
the 14th December 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
HAMILTON BEATTIE, of No. 11, Dowgate Hill, London, Civil Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of June, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,

page_text: the said Joseph Hamilton Beattie, Her special licence that 1, the said
Joseph Hamilton Beattie, my executors, administrators, and assigns, or such
others as I, the said Joseph Hamilton Beattie, 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 THE MEANS OF PREVENTING THE FORMATION
OF AND IN THE REMOVAL OF INCRUSTATIONS OR DEPOSITS FROM STEAK ENGINE
BOILERS," a communication to me from abroad by Joseph Marks, of the City of
Montreal, upon the condition (amongst others) that I, the said Joséph
Hamilton Beattie, 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 Joseph Hamilton Beattie, 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 :-
My Invention consists of a new and useful anti-incrustation powder for the
removal of deposits off the internal surfaces of steam-generating boilers without
injury to the metallic substance thereof, and of which the following is a full
and exact description:-A proportionate combination of ingredients each by
weight thus:-Muriatic acid, twenty-five hundredths; ammonia, twenty-five
hundredths; the pure salt of the native sugar cane, thirty-three hundredths,
mixed with mahogany dust, seventeen hundredths.
Having thus stated of what my Invention consists, I will now explain the
method of manufacturing the same.
First mix muriatic acid and ammonia, thoroughly pulverize the salt obtained,
then add the pure salt of the native sugar cane also pulverized, the whole to
be properly mixed with the mahogany dust.
The advantages of the use of the above combination are that the substance
used penetrates through the deposit to the metallic substance of the boiler and
will not penetrate the metallic substance thereof; it also prevents any foaming
or priming in the boiler during the process of removing the deposit therefrom,
and any slight leakage that may be caused by the removal of the deposit will
be immediately stopped.

so as to clean out the displaced deposit. This will be quite sufficient to
effectually clean any boiler of the deposit, and in order to prevent any
further accumulation of the deposit within the boiler it would be well to use
one half pound per diem in the feed water used.

dients as given above are the best for use in the most usual cases, but that the
proportions may be varied to suit special circumstances, and that what I claim
is, the use of the various combination of ingredients stated above for the
purpose mentioned, and that I do not claim the use of the ingredients
separately.
In witness whereof, I, the said Joseph Hamilton Beattie, have hereunto
set my hand and seal, this
day of December, in the year
of our Lord One thousand eight hundred and sixty-four.
