LETTERS PATENT to Sydney Pitt of Sutton in the County of Surrey, for an
Invention of "A NEW COMPOSITION FOR PREVENTING. INCRUSTATION IN
BOILERS" communicated to him from abroad by Alexander August Rosenberg
of Fellin (Livland) Olga Konstantinowna Hoberg of St Petersburg and Valdimir
Vassiljewitsch Zoubkoff of St Petersburg Russia
:
PROVISIONAL SPECIFICATION left by the said Sydney Pitt at the Office of
the Commissioners of Patents on the 9th July 1883.
SYDNEY PITT of Sutton in the County of Surrey "A NEW COMPOSITION FOR
PREVENTING INCRUSTATION IN BOILERS" [communicated to him from abroad by
Alexander August Rosenberg of Fellin (Livland) Olga Konstantinowna Hoberg of
St Petersburg and Valdimir Vassiljewitsch Zoubkoff of St Petersburg Russia]
The invention has for its object a new composition for preventing incrustation
in steam boilers.
This new composition consists in a mixture of raw potatoes (not, peeled) sweet,
peeled Chestnuts, and common mashed or soaked peas.
The best results are obtained by taking on one hundred (100) kilograms of
potatoes about one (1) kilogram of chestnuts, and one (1) kilogram of peas, or, more
precisely, on one hundred (100) kilograms of potatoes-1.04166..... kilograms of
Chestnuts, and. 1.04166... kilograms of peas (ie-on one bundred Russian pounds
of potatoes: one hundred zolotniks of chestnuts and one hundred zolotniks of peas)
This proportion may, naturally, vary in a small degree without interfering with
the nature of the invention.
The quantity of the proposed new composition wanted for a given quantity of
water, depends on the amount of lime and magnesia salts, and of inorganic
substances in the water, and may be ascertained by experiment
When employing this composition all impurities of the water settle down in the
boiler in the form of mud, and thus incrustation is prevented.
-Trials have shown that by employing this new composition for some considerable
time even incrustations already existing in boilers are removed.

A NEW COMPOSITION FOR
PREVENTING INCRUSTATION IN BOILERS A communication to me from abroad by
Alexander August Rosenberg of Fellin (Livland) Olga Konstantinowna Hoberg of
St Petersburg and Valdimir Vassiljewitsch Zoubkoff of St Petersburg Russia
The invention has for its object a new composition for preventing incrustation
in steam boilers.
This new composition consists in a mixture of raw potatoes (not peeled) sweet
peeled chestnuts and common mashed or soaked peas.
The best results are obtained by taking on one hundred (100) kilograms of
potatoes.about one (1) kilogram of chestnuts and one (1) kilogram of peas or,
more precisely, on one hundred (100) kilograms of potatoes 104166 kilograms of
chestnuts and 104166 kilograms of peas (i.e. on one hundred Russian pounds of
potatoes one hundred zolotniks öf chestnuts and one hundred zolotniks of peas).
This proportion may naturally vary in a small degree without interfering with
the nature of the invention.
The quantity of the proposed new composition wanted for a given quantity of
water depends on the amount of lime and magnesia salts and of inorganic
substances in the water and may be ascertained by experiment.
When employing this composition all impurities of the water settle down in the
boiler in the form of mud and thus incrustation is prevented.
Trials have shown, that by employing this new composition for some.considerable
time even incrustations already existing in boilers are removed.
What I claim as novel and desire to secure by Letters Patent is :-
A new composition for preventing incrustation in steam boilers of any kind
consisting in a mixture of raw, not peeled, potatoes-sweet peeled chestnuts and
coinmon mashed for soaked peas in the proportion specified or nearly so.
In witness whereof I the said Sydney Pitt have hereunto set my hand and
seal this seventh day of January in the year of our Lord One thousand eight
