Improvements in Heat Non-conducting Composition for Covering
Boilers, Steam Pipes, Cylinders, Hot Stoves, and the like.
I, CHARLES HARDY, of 4, Grafton Street, Racecommon Road, Barnsley, in the
County of York, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My present invention relates to an improved heat-non-conducting composition
for covering steam boilers or generators, steam or hot-air pipes, cylinders, hot
stoves and the like and the object thereof is to employ certain cheap ingredients
which when mixed together in certain proportions may be easily applied in a
plastic condition and will subsequently harden or set and set and form a more
effective non-conducting covering and will become more solid and impervious
than other compositions hitherto used for the same purpose and is also capable of
a bright and smooth surface, to attain which I employ the following ingredients
and mix and apply the same in the manner set forth.
I moisten pulverized rock and get it up to a viscous paste condition, likewise
blue fire-clay and shale separately.
I then take two and a half measures of said rock, and three similar measures
of said shale and one and a half measures of said blue fire-clay and thoroughly
mix them together with a sufficient quantity of porous material such as cotton,
flax or similar waste or hair, and in some cases where the covering is exposed to
the weather a small quanty of tar is added. These several ingredients I mix
together until a homogeneous and neat viscous paste is produced when apply
it to the surfaces required to be covered in layers with a trowel in the usual way
until the required thickness of covering is produced.

Improvements in Heat Non-conducting Composition for Covering
Boilers, Steam Pipes, Cylinders, Hot Stoves, and the like.
I, CHARLES HARDY, of 4, Grafton Street, Race-Comanon Road, Barnsley, in the
County of York, 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:―
If present invention relates to an improved heat non-conducting composition

which when mixed together in certain proportions may be easily applied to the
surfaces required to be covered when in a plastic condition and will subsequently
harden or set and will form a more effective non-conducting covering and will
become more solid and impervious than other non-conducting compositions
hitherto generally used for similar purposes, and my improved composition is
also capable when set of a bright, and smooth surface..
To attain which I employ the following ingredients and mix and apply the
same in the manner set forth.
1
I moisten pulverized freestone rock of a brown or blue nature and get it up to
a viscous paste condition and I likewise moisten .blue clay and shale separately
and get them to a similar condition.
I then take two and a half measures of said freestone rock, and three similar
measures of said shale, and one and a half measures of said blue clay, and I mix
them thoroughly together with a sufficient quantity of porous material such as
cotton, flax, or similar waste or hair, and in some cases where. my improved cover-
ing is exposed to the weather I add a small quantity of tar or liquid ammonia.
The aforesaid ingredients I mix up together until a homogeneous and neat
viscous paste is produced and I then apply this to the surfaces required to be covered
by means of a trowel and in layers until the required thickness of covering is
produced.
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:
1. In heat non-conducting covering composition the combination as ingredients
of two and a half measures of freestone rock, three similar measures of shale,
and one and a half similar measures of blue clay with porous material and with
or without tar or liquid ammonia substantially as described.
2. The combination of the several ingredients hereinbefore described mixed
and applied in the manner and for the purpose stated.
Dated this 12th day of April 1898.
