PROVISIONAL SPECIFICATION.
A Fluid for Removing and Preventing Incrustation in Steam
Boilers.
I, RICHARD COSSLETT, of 1 Westminster Villas, Weston, Bath, contractor, do
hereby declare the nature of this invention to be as follows:-
This invention consists in a fluid for removing and preventing incrustation in
steam boilers. The fluid is composed of a mixture of a mineral illuminating oil
with a mineral lubricating oil. The oils, previously mixed together, are added to
the water in the boiler. In a boiler where scale or incrustation has already been
formed, the oils, not having an affinity for the incrustation, percolate through the
same and on coming into contact with the heated boiler plates are expanded, thus
forcing off or dislodging the incrustation from the plates.
In new and clean boilers adhesion of incrustation to and accumulation thereof on
the plates are prevented by the action of the oils, in contact with the plates.
The proportions in which the oils are mixed together and in which the mixture is
added to the water vary with the character of the latter.
Dated this 3rd day of January 1889.

COMPLETE SPECIFICATION.
A Fluid for Removing and Preventing Incrustation in Steam
Boilers.
RICHARD COSSLETT of 1 Westminster Villas, Weston, Bath, Contractor, 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:-
The Invention consists of a fluid for removing and preventing incrustation in
steam boilers. The fluid is composed of a mixture of mineral illuminating oil with
mineral lubricating oil. Those extracted from coal and shale are best suited to the
purpose. The oils, previously mixed together are added to the water in the boilers.
In a boiler where scale or incrustation has already been formed the oils, percolating
through the incrustation on coming into contact with the heated boiler plates are
expanded, thus forcing off or dislodging the incrustation from the plates. In new
and clean boilers adhesion of incrustation to and accumulation thereof on the plates
are prevented by the oils impregnating the scum and residuum and thereby pre-
venting the cohesion of the particles and their adhesion to the plates and tubes.
The proportions in which the oils are mixed together and in which the mixture is
added to the water vary with the character of the latter. The best proportions to use
in the steam boilers are half a pint per week of six working days for a ten-horse
power boiler; one pint per week of six working days for a twenty-horse power boiler
and an additional half pint for each additional ten-horse power.
For boilers working
night and day, double these quantities. For foul boilers additional quantities should
be used until they are clean.
The above specified quantities are the best average, but they should be regulated
by the amount of deposit increasing or decreasing the quantities according to the
cleanness or foulness of the plates and tubes.

page_text: Having now particularly described and ascertained the nature and object of
my said Invention and in what manner the same is to be performed I declare that
what I claim is
The said invention and application of a mixture of illuminating mineral oil and
lubricating minoral oil for the removal and prevention of incrustation in steam boilers
substantially as hereinbefore set forth and described.
Dated this 26th day of September 1889.
RICHARD COSSLETT,
Applicant.
