PROVISIONAL SPECIFICATION.
An Improved Composition for Preventing Incrustation in and
Facilitating the Cleaning of Steam-boilers.
We, WILLIAM GROVE, Engine Driver, and LEWIS LEWIS, Postmaster, both of
Pontywain, near Newport, in the County of Monmouth, do hereby declare the nature
of this invention to be as follows:--
The object of our invention is to provide an improved boiler-composition, that
is to say, a composition. for preventing incrustation in steam-boilers and for
facilitating the cleaning of such boilers.
-
Our improved composition is made with different kinds of apples mixed with
oak-apples or acorns or with both oak-apples and acorns. These fruits or vegetable
products we grind together in a suitable mill until they are intimately mixed and
are brought to the consistency of a slimy paste. Or we mix the said fruits or
vegetable products in any other convenient manner. The composition thus produced
is ready for use and may be packed in casks, cans or other suitable receptacles for
storage or transport.
We find it advantageous, in the manufacture of our improved composition, to
employ the following as ingredients, viz. :-Apples known by the names
"Bitter-
sweet," "Foxwhelp" and "Ruffcoat" (Russet), and either oak-apples or acorns or
both of these vegetable products. There are, however, other apples which are adapted
for the purpose of our invention.
In the manner above described, we provide an anti-corrosive composition which can
be used in all kinds of boilers and will keep them clean and preserve the boiler-plates
and tubes.
The improved composition may be dissolved in a suitable tank and introduced into
the hoiler by means of a pump or injector. It will cause all sediments or deposits to
settle at the bottom of the boiler so that they can be easily discharged from time to
time through a blow-off cock. The said composition therefore, prevents incrustation
so that, in cleaning the boiler, it is not necessary to use chipping hammers or the like,
all that is required being to wash the inside of the boiler with water through a hose
and nozzle. The said composition, moreover, keeps clean the cocks and valves.
attached to the boiler and prevents sticking of the valves; it also prevents or greatly.
diminishes priming.
Although our composition consists essentially of ingredients such as those above
mentioned, yet it may be advantageous, in some instances, to add other ingredients
thereto, for the purpose of rendering the composition more efficient in its action or for
other purposes.

COMPLETE SPECIFICATION.
An Improved Composition for Preventing Incrustation in and
Facilitating the Cleaning of Steam-boilers.
We, WILLIAM GROVE, Engine Driver, and LEWIS LEWIS, Postmaster, both of
Ponty wain, near Newport, in the County of Monmouth, 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 object of our. invention is to provide an improved boiler-composition that is
to say, a composition for preventing incrustation in steam-boilers and for facilitating
the cleaning of such boilers.

page_text: Our improved composition is made with different kinds of apples mixed with
acorns or oak-apples or with both acorns and oak-apples. We reduce these fruits or
vegetable products to pulp and intimately mix them together in any convenient
manner so as to bring the mixture to the consistency of a slimy paste. The com-
position thus produced is ready for use and may be packed in casks, cans or other
suitable receptacles for storage or transport.
We prefer to use cider apples in making our improved composition and we find that
apples such as those known by the names "Bittersweet," "Foxwhelp" and "Ruffcoat "
(Russet) can be used with advantage.
The said fruits or vegetable products are preferably gathered when in their green
condition, and should be ground or pulped as soon as practicable after they are
gathered. The acorns and oak-apples are by preference ground or pulped separately
from the apples, and the pulp is stored in open casks, that is to say, in casks with the
heads removed, the surface of the mass being covered with water. The apples are
treated and stored in a similar manner. The said fruit or vegetable products can be
ground in any suitable mill or pulping machine.
In preparing the composition for use, we mix about four gallons of the
oak-fruit pulp with about ten gallons of the apple pulp, and the mixture, after
being well ground together is put into casks or other convenient receptacles for
storage or use.
It is desirable, if the composition is to be kept in store after casking, that the bung
of the cask should be left out; if the bung is inserted to close the cask for carriage
or transport, it should, on the arrival of the cask at its destination, be removed
from the cask the cask should be opened to prevent or diminish fermentation and the
surface of the composition should be preferably covered with water.
Our improved composition may be mixed with water in a suitable tank and intro-
duced into the boiler by means of the usual feed-pump or injector.
Its action is such that the adherence of the incrusting particles to the heated surfaces
of the boiler is prevented, and all sediments or deposits are caused to settle at the
bottom of the boiler, so that they can be easily discharged from time to time through
the blow-off cock. The said composition, therefore, prevents incrustation, so that, in
combination the boiler, it is not necessary to use chipping-hammers or the like, all
that is required being to wash the inside of the boiler with water by means of a hose
and nozzle. The said composition, moreover, keeps clean the cocks and valves attached
to the boiler and prevents sticking of the valves; it also prevents or greatly diminishes
priming.
In the manner above described, we provide a non-corrosive composition which can
be used with all kinds of hard waters and in all kinds of boilers, and which will keep
the boiler clean and preserve the boiler-plates and tubes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we wish it understood that
we claim :-
