In addition to the above, I sometimes find it advantageous to soak leather
in water for a considerable time, and add the water to the above ingredients.
The compound may be used either in a liquid or dry state, and may be mixed
with or dissolved in the water in the hot well or feed-water, or it may be put into the
boiler direct.
By the use of the above compound the scale may be removed from boiler plates
and passed away through the blow-off cocks or its formation may be prevented; and
the plates & tubes may be prevented from burning and rusting.

COMPLETE SPECIFICATION.
An Improved Anti-fouling Compound for Steam and other Boilers.
I, CHARLES Hooк, of 39, Kneller Road, Brockley, London, S.E., Ironfounder,
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 :-
The object of my invention is to manufacture an improved mixture or compound
for the prevention and removal of scale, deposit, incrustation and rust in steam and
other boilers.
In carrying out my invention I mix together common soda ash, bark, lime and
pigeons' manure, in the following proportions, (be the same little more or less) viz. :—

page_text: The compound may be used either in a liquid or dry state, and may be mixed
with or dissolved in the water in the hot-well or feed-water, or it may be put into
the boiler direct. The compound may also be used in an analogous manner in
preventing or removing scale from laundry boilers and coppers, and analogous
vessels used in laundry operations.
By the use of my improved compound the scale may be removed from boiler
plates, and passed away through the blow off cocks, or otherwise removed; or the
formation of scale may be prevented by dissolving the compound in the water
previous to introducing the same into the vessel, and the plates and tubes may thus
be preserved and protected against burning and rusting.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved, anti-fouling compound for steam and other boilers, substantially
as herein before described.
2. The application and use of the improved anti-fouling compound to and for
the purposes hereinbefore described.
