AN IMPROVED COMPOSITION FOR PREVENTING AND REMOVING INCRUSTATION IN STEAM BOILERS, SUCH COMPOSITION ALSO PREVENTING PRIMING, AND ACTING AS A LUBRICATOR FOR STEAM ENGINE CYLINDERS
Year: 1877

page_text: LETTERS PATENT to Elijah Hunter, of Leeds, in the County of York, for the
Invention of "AN IMPROVED COMPOSITION FOR PREVENTING AND REMOVING
INCRUSTATION IN STEAM BOILERS, SUCH COMPOSITION ALSO PREVENTING
PRIMING, AND ACTING AS A LUBRICATOR FOR STEAM ENGINE CYLINDERS."
Sealed the 4th January 1878, and dated the 26th July 1877.
PROVISIONAL SPECIFICATION left by the said Elijah Hunter at the Office
of the Commissioners of Patents on the 26th July 1877.
ELIJAH HUNTER, of Leeds, in the County of York. "AN IMPROVED COMPOSITION
FOR PREVENTING AND REMOVING INCRUSTATION IN STEAM BOILERS, SUCH COM-
POSITION ALSO PREVENTING PRIMING, AND ACTING AS A LUBRICATOR FOR STEAM
ENGINE CYLINDERS."
My improvements refer to a combination of several substances, as hereafter
described, which I inject or otherwise place in the boiler. This composition
mixes with the water in the boiler, and thereby is brought in contact with the
incrustation or scale, which is removed, loosened, or prevented from forming.on
plates by the chemical action of the composition.
The ingredients contained therein are as follows:-)
-For about fifty gallons of the
composition I take about the following quantities, viz. :-
Common soda
Irish moss
Catechu
Water -
-
-
ninety-one pounds.
eleven and a half pounds.
seventeen pounds.
fifty-five gallons.
These are placed in a suitable receptacle, and boiled for about two hours, after
which I strain off the liquor, which is then ready for use.
The quantities of the ingredients used in forming the composition of course may
be varied in accordance with the quantity or nature of the scale or incrustation.

page_text: When the composition is supplied at the commencement of the working of the
boiler, and continued as may be required, the scale or incrustation is prevented; but
when required to remove the incrustation or scale after being formed and adhering
to the plates, the composition may be pumped or injected into the boiler by any
ordinary known means.
The herein-before mentioned composition also prevents priming, and acts as a
lubricator for steam cylinders by passing thereinto with the steam.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Elijah Hunter in the Great Seal Patent Office on the 26th
January 1878.
ELIJAH HUNTER, of Leeds, in the County of York. "AN IMPROVED COMPOSITION
FOR PREVENTING AND REMOVING INCRUSTATION IN STEAM BOILERS, SUCH COM-
POSITION ALSO PREVENTING PRIMING, AND ACTING AS A LUBRICATOR FOR STEAM
ENGINE CYLINDERS."
My improvements refer to a combination of several substances, as hereafter
described, which I inject or otherwise place in the boiler. This composition mixes
with the water in the boiler, and thereby is brought into contact with the incrusta-
tion or scale, which is removed, loosened, or prevented from forming on plates by
the chemical action of the composition.
The ingredients contained therein are as follows:-For about fifty gallons of the
composition I take about the following quantities, viz. :—
Common soda
Irish moss
Catechu
nintey-one pounds.
eleven and a half pounds.
seventeen pounds.
fifty-five gallons.
Water
-
Or instead of the common soda and Irish moss I may in some cases use hypo-
sulphate of soda, about 45 pounds, combined with ground oak bark, about 65 pounds.
These are placed in a suitable receptacle, and boiled for about two hours, after which
I strain off the liquor, which is then ready for use.
The quantities of the ingredients used in forming the composition of course may
be varied in accordance with the quantity or nature of the scale or incrustation.
When the composition is supplied at the commencement of the working of the
boiler, and continued as may be required, the scale or incrustation is prevented; but
when required to remove the incrustation or scale after being formed and adhering
to the plates, the composition may be pumped or injected into the boiler by any
ordinary known means.
..
The herein-before mentioned composition also prevents priming, and acts as a
lubricator for steam cylinders by passing thereinto with the steam.
And having thus described and ascertained the nature of this Invention, I declare
that I claim the manufacture and application of a boiler composition from the

page_text: herein-before named ingredients when combined and prepared, substantially as set
forth.
In witness whereof, I, the said, Elijah Hunter, have hereunto set my hand
and seal, this Twenty-second day of January, in the year of our Lord One
thousand eight hundred and seventy-eight.
