I, EDWARD BROOKE of the Fieldhouse Fire. Clay Works, Huddersfield in the
County of York, Fire Brick, and Sanitary Tube Manufacturer do hereby declaré
the nature of my Invention for "IMPROVEMENTS IN THE MANUFACTURE OF A
REFRACTORY MATERIAL TO BE USED FOR LINING FURNACES, ALSO TO BE USED
IN THE MANUFACTURE OF REFRACTORY BRICKS, BLOCKS TUYERES, PIPES, AND
SIMILAR ARTICLES," to be as follows:-
:-
"
The object of my Invention is to make a plastic and fire resisting material for
lining Bessemer vessels and other furnaces, the said material being also capable of
being made into moulds or forms adapted for metallurgical purposes.
Materials for the above purposes have been composed of silica, ganister, quartz
and other nearly pure forms of silica combined with tar or other hydrocarbon
products, but in practice I find that such combinations alone do not form a
sufficiently binding material for the purposes herein mentioned, as the tar or carbon
part of the mixture very soon sets and becomes hard rendering the cement unfit
for use.
To produce such mixture or material as will be more suitable for the purpose is
the object of my Invention, and this I accomplish by the employment of certain
forms of nearly pure silica, ganister, quartz, and fire clay in combination with a
preparation of tar or other hydrocarbons.
Previous to the tar being mixed with the silica and fire clay I prefer to add a
small quantity of oil with the said tar (by boiling) which prevents it setting and
becoming hard, whereby the said materials after being ground together, form and
constitute a fire resisting material of such a refractory nature that has not hitherto
been produced for furnace linings, or for blocks, or other articles employed for
metallurgical purposes.

I, EDWARD BROOKE of the Fieldhouse Fire Clay Works, Huddersfield in the
County of York, Fire Brick and Sanitary Tube Manufacturer do hereby declare
the nature of my Invention for " IMPROVEMENTS IN THE MANUFACTURE OF A
REFRACTORY MATERIAL TO BE USED FOR LINING FURNACES, ALSO TO BE. USED
IN THE MANUFACTURE OF REFRACTORY BRICKS, BLOCKS, TUYERES, PIPES, AND
.SIMILAR ARTICLES" 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 my Invention is to make a plastic and fire resisting material for
lining Bessemer vessels and other furnaces, the said material being also capable of
being made into moulds or forms adapted for metallurgical purposes.
The materials hitherto used for the above purposes have usually been composed
of silica, ganister, quartz, and other nearly pure forms of silica, combined with
liquid tar or other hydrocarbon products, but in practice I find that such
combinations alone do not form a sufficiently binding material for the purposes
herein mentioned as the tar or carbon part of the mixture very soon sets, and
becomes hard rendering the cement unfit for use.
To produce such mixture or material as will be more suitable for the purpose
is the object of my Invention, and this I accomplish by the employment of certain
forms of nearly pure silica, ganister, quartz and fire clay in combination with a
preparation of liquid tar, or other hydrocarbon products.
Previous to the liquid tar being mixed with the silica and fire clay, I prefer to
add a small quantity of oil with the said tar which is done by boiling both together
in a pan, whereby the tar is prevented from setting and becoming hard.
The modus operandi is as follows-When it is intended to make a cement such as
is herein described an ordinary mortar mill is employed into which I place-say-
90 parts of stone, 12, parts of fire clay 3 gallons of the mixture of boiled tar, and
oil, and 12 gallons of water.
These are operated upon by the mortar mill, and ground together until thoroughly
mixed, thereby forming and constituting a fire resisting material of such a
refractory nature as renders it most suitable for furnace linings, or for block or
other articles employed for metallurgical purposes.
Although I have for the sake of clearness given proportions for a certain mixture,
I would observe that the proportions will vary according to circumstances and the
purpose for which the cement is required-as for instance-when the cement is
intended to be used for lining very hot furnaces, a greater proportion of stone, and
a less proportion of fire clay would be required.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is,
The manufacture of a refractory material, or composition consisting of a
combination of silica, fire clay and liquid tar, or hydrocarbon with or without oil,
mixed and ground with water, in manner and for purposes set forth.
