Improvements in the Petrifaction or Incrustation of Porous or
other Substances.
I, JOHN RODGERS, of Mill Street, Openshaw, near Manchester, in the County
of Lancaster, Master Slater, do hereby declare the nature of this invention to be
as follows:
This invention has reference to the process of petrifying or covering by incrusta-
tion substances porous or otherwise.
and
or
I place within a tank, preferably conical or of other suitable shape, flint, iron,
lead limestone other mineral substance, and allow water drawn from a well
to be continually running into and upon such mineral substances. I may, as
found desirable, place therein a regulated quantity of water, sufficient to keep
each substance in touch with the other. In addition to such other ingredients,
I may add lime water at suitable periods to aid in the deposit.
The base or side of the tank I perforate with a number of holes, and in or
near such perforations, I place suitable strips or cords of absorbent material to
act as a means for slowly drawing the liquid from the tank. The liquid passes
along these strips or cords, and runs slowly over the article to be treated.

COMPLETE SPECIFICATION.
Improvements in the Petrifaction or Incrustation of Porous or
other Substances.
I, JOHN RODGERS, of Mill Street, Openshaw, near Manchester, in the County
of Lancaster, Master Slater, 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 has reference to the process of petrifying or covering by in-
crustation substances porous or otherwise.
It will be fully described with reference to the accompanying drawings in
which suitable apparatus is illustrated for carrying out the invention.
Fig. 1. Front elevation.
Fig. 2. Sectional elevation.
The apparatus is constructed with a tank A of any suitable shape to contain
a liquid, preferably conical as shown.

page_text: The tank A is perforated at or near the bottom with a number of small holes
or perforations a and in each of these perforations is fitted a strip or cord B of
absorbent material over which the liquid slowly trickles or is slowly drawn
from the tank.
The cords B are arranged in any suitable way to rest upon or over the article
to be treated and the liquid is guided by these cords to such article over which
it slowly flows.
The tank A is mounted upon a stand such as C which may be provided with
an inlet pipe D running through the centre or other convenient place to keep
the tank supplied with water. Such supply pipe may be dispensed with and the
tank be filled when required by removing the lid A¹. At the base of the stand C
is a reservoir E to catch the waste water which may be lifted back into the tank
or allowed to run away through a drain pipe as may be found most convenient.
Within the tank are placed blocks or pieces of flint, iron, iron ore, lead, limestone
and
or
other mineral substance and water is allowed (preferably spring water) to
be continually running into and upon such minerals which will be slowly and
gradually dissolved by the water. In addition, lime or lime water may be added
to aid the deposit.
The water flows slowly from the tank A over the strings B onto any article
placed below them and gradually petrifies or deposits thereon the chalky or
mineral matter which it has absorbed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The method of petrifying or incrusting porous or other bodies substantially
as herein described.
2. The apparatus for petrifying or incrusting porous or other bodies substantially
as described and shown.
