Year: 1884

page_text: I WILLIAM JOHN BARDIN GRAHAM of N° 1 Whitehouse Villas, Upper
Woodland Terrace Charlton in the County of Kent, Brick, Lime, Loam, & Sand
Merchant, do hereby declare the nature of my said Invention for "AN IMPROVED
FIRE RESISTING COMPOUND OR MATERIAL" to be as follows:-
My Invention relates to an improved fire resisting compound or material. This
compound or material is designed for use in lining or repairing furnaces or parts
thereof, cupolas, backs for stoves, ladles or the like, which are subjected to or have
to sustain great heat, such compound or material may moreover be used in the
construction of such furnaces or other structures or devices with or without being
combined with other fire resisting material.
My improved fire resisting compound or material consists of a mixture of silica,
carbonized silicated clay, and clay, such ingredients being mixed in suitable
proportions according to the particular purpose for which the compound is to
be used.

do hereby declare the nature of my Invention for "AN IMPROVED FIRE RESISTING
COMPOUND OR MATERIAL and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
"
My Invention relates to an improved fire resisting compound or material.-This
compound or material I employ as a lining or coating for, or in the repairing of,
furnaces or parts thereof, cupolas, backs of stoves, ladles or other structures or
devices which are subjected to or have to sustain great heat.
Such compound or material may be used in the construction of such furnaces
or other structures or devices with or without being combined with other fire
resisting material.
My improved fire resisting compound or material consists of a mixture of silica,
silicated carbonized clay (that is to say clay which has been carbonized in a retort)
and clay, such ingredients being mixed in suitable proportions according to the
particular purpose for which the compound is to be used. For instance in preparing
my compound or material for lining or repairing furnaces I find that a convenient
admixture of the various substances or material above enumerated is as follows
4 parts
Silica
Silicated carbonized clay
Clay
1 part
-
1 parts
I do not however limit myself to such proportions as it will be evident that they
may be considerably varied according to the particular purpose or object for which
the compound or material is employed.
Such compound or material when employed as a lining for, or in the repairing of,
furnaces built of other fire resisting material will preserve the edges thereof from
fluxing and one important advantage derived from the use of my improved
compound or material is that so soon as a furnace, cupola, or similar structure has
been lined or repaired with such compound or material the said furnace or the
like may be immediately relit and the blast for melting purposes admitted without
further delay.
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 improved fire resisting compound or material consisting of the ingredients or
substances herein set forth for the purpose specified.
Dated the 20th dow of New 1884.
