PROVISIONAL SPECIFICATION.
Improvements in Boiler Compositions or Solutions for Internal
Application to Steam Boilers.
I, FREDERICK ARTHUR CLAYTON of 62 Cyprus Road, Bootle, Liverpool,
Manufacturer of Boiler Compositions etc., do hereby declare the nature of this
invention to be as follows:-
This invention relates to what are known as "boiler solvents" compositions or
solutions which are used in a fluid state for application to the interior of steam
boilers to obviate or reduce corrosion and pitting or other like evils to which the
interior of steam boilers are liable.
For this purpose I compound and manufacture a fluid mixture or "solvent" in
the following manner :-
=
I take hydrate of sodium (sodic hydrate NaHO or Na2OH2O) and by
means of water and heat as is well understood 1 saturate same to about ten per cent.
(10%) with zinc or saturate same with as much zinc as it will hold in solution
from scrap zinc and to this mixture (zincate of soda) before cooling I add a
percentage of tannate of soda.
My formula will thus be as follows:-
--
Caustic soda.
Oxide of zinc.
Tannate of soda.
Water.
In suitable proportions.
These ingredients are thoroughly and intimately mixed and blended together and
the resulting solution or fluid forms the composition or solvent which can be applied
to the interior of steam boilers while under steam as is well understood or in any
suitable or desired manner.
Dated this 14th day of April 1893.

Application to Steam Boilers.
I, FREDERICK ARTHUR CLAYTON of 62 Cyprus Road, Bootle, Liverpool,
Manufacturer of Boiler Compositions, etc., do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to what are known as "boiler solvents" compositions or
solutions which are used in a fluid state for application to the interior of steam
boilers to obviate or reduce corrosion pitting and incrustation or other like evils to
which the interior of steam boilers are liable.
For this purpose I compound and manufacture a fluid mixture or "solvent" in
the following manner :-
I take hydrate of sodium (sodic hydrate NaHO or Na2OH2O) and by
means of water and heat as is well understood I saturate same to about ten or
eleven per cent. (10 or 11%) with zinc or saturate same with as much zinc as it

cooling I add a percentage of tannate of soda.
My formula will thus be as follows and in the following proportions or there-
abouts :-
:―
Caustic soda
Oxide of zinc
-
Tannate of soda
Water
-
29.00.
11.00.
-
5.00.
"
55.00.
These ingredients are thoroughly and intimately mixed and blended together and
the resulting solution or fluid forms the composition or solvent which can be applied
to the interior of steam boilers while under steam-for instance with the feed
water or by separate injection-as is well understood or in any suitable or desired
manner.
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 :-
The compounding and manufacture of a solution for use in steam boilers con-
sisting of saturating sodic hydrate and water with zinc by the aid of heat then
adding five per cent. or thereabouts of tannate of soda before cooling all thoroughly
mixed and blended in about the proportions substantially as and for the purposes
herein before set forth.
