IN STEAM BOILERS, MARINE, LAND, OR PORTABLE to be as follows:-
:-
I protect them from deposit contained in the water used for generating steam.
adhering to the surfaces in the form of incrustation. I paint or wash over the
surfaces exposed to incrustation with mixtures made of zinc or other metallic
paints asbestos; plumbago; lamp-blank or other carbons: lead and enamel
paints or finely ground earthy or vegetable compounds; petroleum; naphtha:
dryers; and spirits. The paint or wash is applied with a brush to the metallic
surfaces exposed to the incrustation. The incrustation of itself scales off in flakes
while the boiler is at work and any remaining can be removed by means of a brush
or scrubber.
Each time the boiler is cleaned the paint or wash can be applied afresh-its action
being like parting sand in moulding keeping separate the surface of incrustation
and the metallic surface of the boiler.
The surfaces of the boiler are kept clean and preserved from corrosion thereby-
making the boiler more efficient in heating power, more durable, and safer from
over heating and collapse.

An Improved Method of Preventing Incrustation and Corrosion
in Steam Boilers.
WILLIAM HYDE Engineer 81 Springfield Terrace Falls Road Belfast, County of
Antrim, Ireland do hereby declare the nature of my invention for AN IMPROVED
METHOD OF PREVENTING INCRUSTATION AND CORROSION IN STEAM BOILERS,
MARINE LAND OR PORTABLE, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :—
I protect them from deposit contained in the water used for generating steam
adhering to the surfaces in the form of incrustation.
I paint or wash over the surfaces exposed to incrustation with mixtures made of
zinc or other metallic paints: asbestos: plumbago: lamp black or other carbons:
lead and enamel paints or finely ground earthy or vegetable compounds, petroleum,
naphtha, dryers, and spirits. I do not bind myself to any of these paints. Other
washes of a parting nature may be used. The paint or wash is applied with a
brush to the metallic surfaces exposed to the incrustation. The incrustation of
itself scales off in flakes while the boiler is at work and any of it remaining can
be removed by means of a brush or scrubber. Before applying it to an old boiler
where incrustation has taken place it is necessary to have the incrustation chipped
off leaving the metallic surface clean for the paint.
Each time the boiler is cleaned the paint or wash is to be applied afresh-its
action being like parting sand in moulding, keeping separate the surface of
incrustation and the metallic surface of the boiler.
The surfaces of the boiler are kept clean and preserved from corrosion thereby,
making the boiler more efficient in heating power, more durable, and safer from
overheating and collapse.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare what
I claim is
:
1st. The protection of Steam Boilers against incrustation and corrosion by
applying to the internal surfaces a parting paint or wash.,
Dated this 16th day of January 1886.
WILLIAM HYDE.
