I, JOHN ILLINGWORTH, of Ridings Mill, Whitelee, Batley, in the County of York,
Flock Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention in pipes, gas retorts, and other hollow articles consists in pouring
molten metal upon the outside of pipes, gas retorts, or other vessels, so as to render
the said articles more durable for the passage therethrough of acids, either in a liquid
or vapour state; also to make such articles resist the destructive action of fire and
heat, and less liable to breakage.
In carrying out my invention I obtain a glazed or unglazed earthenware pipe or
other article, which I place into an ordinary stove for the purpose of making the pipe
thoroughly dry, such pipe being afterwards filled with ordinary foundry sand. The
pipe or other article is then placed into a mould and occupies the position of a core.
Molten metal is now poured into the mould in the usual manner, and on the metal
cooling and contracting it becomes firmly fastened to the outside of the pipe; at the
same time, the contracting of the metal solidifies and compresses the earthenware
shell, and the two become a homogeneous mass. When the pipe has cooled it is taken
from the mould in the ordinary manner, and the sand within the shell removed
therefrom. By this means the iron pipe is made with a firm, solid, compact lining,
which will be found very durable when used for the passage of acids, and in the
case of retorts, they will resist the action of fire to a greater extent than the ordinary
form of fire clay retorts at present in use.

page_text: I, JOHN ILLINGWORTH, of Ridings Mill, Whitelee, Batley in the County of York,
Flock Manufacturer 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 :-
My invention in pipes, gas retorts, and other hollow or dished articles consists in
pouring molten metal upon the outside of pipes, gas retorts, or other vessels, so as to
render the said articles more durable for the passage therethrough of acids, either in a
liquid or vapour state; also to make such articles resist the destructive action of fire
and heat, and less liable to breakage.
In order that my invention may be more fully understood, I will now make
reference to the accompanying sheets of drawings illustrative thereof.
Fig. 1 represents a flanged pipe formed around an earthenware pipe or shell.
Fig. 2 represents a set pan or round boiler such as those used for boiling clothes.
Fig. represents a gas retort formed around an earthenware shell.
Fig. 4 represents a gulley or trap.
In these several illustrations A represents the earthenware part, and B the cast
metal part.
Molten
In carrying out my invention the glazed or unglazed earthenware part is first of all placed
into an ordinary drying stove for the purpose of making the earthenware thoroughly
dry, which is afterwards filled with ordinary foundry sand. The earthenware shell
is then placed into a mould and occupies therein the position of a core.
metal is afterwards poured into the mould in the usual manner, which metal surrounds
the earthenware shell, and on the metal cooling and contracting it becomes firmly
fastened to the outside of the shell; at the same time the contraction of the metal
solidifies and compresses the earthenware shell, and the two become one homogeneous
mass. When the metal has cooled, it is taken from the mould in the ordinary
manner, and the sand within the shell is removed therefrom. By this means the
hollow metal article is made with a firm solid compact lining, which will be found
very durable when used for the passage of acids; especially will this earthenware
lining be found useful in the case of taps and valves used in chemical works, and all
other purposes where the liquid or fluid passing through is liable to corrode the
parts, and in the case of gas retorts they will materially resist the action of fire to
a greater extent than the ordinary form of fireclay retorts at present in use.
Other hollow or dished articles may be made according to my invention, such as
cooking vessels and the like.
For the purpose of carrying out my invention, the hollow articles may be glazed
or unglazed, whilst in some cases it will not be necessary to burn the earthenware,
but hollow articles composed of dried clay will be sufficient.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The manufacture of pipes, gas retorts, and other hollow articles, with an earthenware
lining or shell, made in the manner substantially as herein described and illustrated
in the drawings.
