PROVISIONAL SPECIFICATION.
An Improved Composition, Mixture, or Cement for Lining or
Re-lining and Jointing, Mending or Renewing Gas Retorts,
Furnaces and the like.
I, ALFRED WILLIAM CROWTHER, of 18, Manor Street, Huddersfield, in the County
of York, Retort Setter, do hereby declare the nature of this invention to be as
follows:-
:-
This invention has reference more particularly to gas retorts and furnaces and
comprises an improved mixture or cement for application to said retorts or furnaces
as a lining to or for re-lining same, or for jointing the retorts or parts of the furnace,
or mending or otherwise renewing the surfaces which have become burnt worn or
indented by subjection to heat or contact of heated substances therewith; said
cement or mixture being, however, applicable for the jointing or making of
joints and renewal or mending of other refractory pipes or parts of analagous
description.
For the purpose of my invention the composition, mixture, or cement is formed by
the admixture, in about equal parts or such other proportion as may be found to
answer, of fire clay or other analagous refractory substance or material and ganister
or silica, to which is added about 25 per cent., or an equivalent proportion of soda,
the whole being ground up and mixed in a mortar pan or the like and made into a
paste by the addition of water, or the mixture may be in the powdered form and
made into a paste as and when required. The cement or mixture is applied to the
joints or to the surfaces or other parts requiring lining mending or patching and,
when set, adheres to or unites with the retort, furnace or part to which it is applied
and does not crack or drop out as do the patching cements now used.
For inclined retorts especially, the above cement is well adapted, and will long resist
the heat and action of tar or other liquids or solids treated therein; for washing out
said retorts the mixture is also advantageous, leaving on the interior walls thereof a
glassy or glazed surface.

I, ALFRED WILLIAM CROWTHER, of 18, Manor Street, Huddersfield, in the County
of York, Retort Setter, do hereby declare the nature of this invention and in what
[Price 8d.]

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention has reference more particularly to gas retorts and furnaces and
comprises an improved mixture or fire cement for application to said retorts or
furnaces as a lining or coating to or for re-lining same, or for jointing the retorts or
parts of the furnace, or mending or otherwise renewing the surfaces which have
become burnt, worn or indented by subjection to heat or contact of heated
substances therewith; said cement or mixture being however, applicable for the
jointing or making of joints and renewal or repairing of other refractory pipes,
cupolas, coke ovens and the like.
1
For the purpose of my invention the composition mixture or cement is formed
by the admixture, in about equal parts or such other proportion as may be found
suitable for the purpose, of earths of a refractory nature such as fire clay, and
gannister or silica. To these refractory earths is added about twenty five per cent.
or an equivalent proportion of soda the whole being ground up and mixed in a mortar
pan or the like and made into a paste by the addition of water, or the mixture may
be supplied in the powdered state and made into a paste as and when required. I
may add to the above, barilla or other equivalent body for increasing the tenacity or
adhering property of the cement for some classes of work, or the barilla, may be
substituted in some cases for the soda.
The cement or mixture is applied in the plastic state to the joints, surfaces or
other parts requiring jointing, mending, or patching and when set, adheres to
or unites with the retort, furnace or part to which it is applied and does not crack or
drop out, as do the patching cements now used. For inclined retorts especially
the above cement is well adapted and will long resist the heat and action of tar or
other liquids or solids treated therein. For washing out said retorts the mixture is
also advantageous leaving on the interior walls thereof a vitreous surface.
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 herein described fire resisting cement, composition, or mixture formed by
the admixture in suitable proportions of earths of a refractory nature such as fire
clay and gannister or silica in combination with soda or its equivalent to which
cement may be added, if required, barilla, or an equivalent substance, substantially
as set forth.
