Body Suitable for Various Useful Purposes (Sanitary and other).
I, EDWARD JOHNSON of 3 Albert Embankment, Lambeth Surrey, Sanitary Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the treatment of certain materials for the manufacture of a
filtering medium or capable of being mixed with other ingredients or substances for
deodorizing, disinfecting or for fertilizing.
For the purpose of my invention I take clay which is rich with oxide of iron and
evaporate the moisture from it by heat. This dried ferruginous clay is granulated
and with the flour or fine dust resulting from this granulation I mix an equal quantity,
by measure,
of clean soot, and thoroughly associate the two by stirring. I then
admix a necessary quantity of tar as to convert the composition into the form or
condition of thick mortar, the tar being used as a binding body and to make the mass
homogenous and plastic.
This compound is dried and then reduced to a similar granular condition to that
before mentioned, and with this granulated material I mix the granulated clay from
which the flour or fine dust had been separated.
The process of carbonizing is done in close retorts until all gas or vapour is ceased
to be given off, the clay granules being through this baking process thoroughly
impregnated with carbon.
This carbonized body can be used in a granulated form in ordinary domestic filters,
in sugar refining, or in sewage works.
If the compound thus prepared and forming a carbonized material is to be used for
purposes other than filtering, it is subjected to the action of pure oxygen in a close
receiver for 2 or 3 hours, the carbon having the power of condensing the oxygen
which converts the substance into a powerful deodorizer.
If the carbonized material is to be used for disinfecting I subject it to the action of
chlorine gas, but if for fertilizing I mix soluble phosphates or other fertilizers
with it.

page_text: The carbonized material prepared as above described I call Feral-Carbon or
Carferal, it being a compound of Carbon, Iron and Alumina and in combination forms
the base for the compositions above mentioned according to the use for which it is
intended.

I EDWARD JOHNSON of 3 Albert Embankment, Lambeth, Surrey, Sanitary Engineer,
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 :-
This invention relates to the treatment of certain materials for the manufacture of a

and with the flour or fine dust resulting from this granulation I mix an equal quantity,
by measure of clean soot and thoroughly associate the two by stirring 1 then admix a
necessary quantity of tar as to convert the composition into the form or condition of

Having now described the nature of my said invention and in what manner the

The improved treatment of materials, or process, herein before described for the
production of a carbonized body suitable for various useful purposes (Sanitary and
other) as set forth
