PROVISIONAL SPECIFICATION.
An Improved Composition for the Covering of Bollers and other
Surfaces.
A communication from JOHN DAVID JONES, of.4, Tiljulla Road, in the suburbs of
Calcutta, India, Mechanical Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
The composition is formed by the mixing in certain proportions of mica,
diatomite, kiesulguhr (known also as fossil meal) fire clay and mineral carbon.
This composition can be used either as a non-conductor of heat on boilers, stoves,
steam pipes, or heating surfaces. of any description, or as a covering for
refrigerators, gunpowder cases, safes and batteries, or for insulations for electrical
purposes, or as a paint, or as dados for damp walls. It can also be formed into
tiles for floors, roofs &c. while, mixed with white or red lead it can be used for
jointing purposes.
The proportions in which it has been found most suitable to mix the several
substances are as follows-
Mica
Kieselgurh
Fire clay
-
Coal carbon
-
60
per cent.
15 per cent..
per cent.
-
10 per cent.
15
It must however be clearly understood that these proportions will not answer
for all and every purpose to which the composition may be applied and that they
must necessarily vary to suit circumstances.

COMPLETE SPECIFICATION.
An Improved Composition for the Covering of Boilers and other
Surfaces.
A communication from JOHN DAVID JONES, of 4, Tiljulla Road, in the suburbs of
Calcutta, India, Mechanical Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 :-
The object of this invention is to provide a composition which shall be non-
conducting, non-inflammable and damp-proof, so that it can be used either as a
non-conductor of heat on boilers, stoves, steam-pipes, or other heating or heated
surfaces or as a covering for refrigerators, gunpowder cases, safes, batteries, and
other devices or it can be used for insulations for electrical purposes either above
or under ground. This composition can further be used with great advantage as a
[Price 8dl

page_text: paint, or as dados for damp walls, or be formed into tiles for floors, roofs, or other
structures while, if mixed with white or red lead, it can be used as a putty for
jointing purposes. It can, in fact, be advantageously used for almost any and
every purpose as is apparent from the variety of uses already indicated.
Tests already made have demonstrated that a saving of at least, 50% of heat or
cold is effected by the use of this invention which is a result exceeding that
attained by any other previously known composition.
The invention consists in the mixing in certain proportions of substances which,
though well known by themselves have never been blended together in the manner
and for the purposes herein described. The substances used in this composition
are ground mica, diatomite kieselguhr (known also as fossil meal or infusorial
earth) fire clay and mineral carbon. These substances when mixed together in the
proportions hereinafter described, and formed into a paste, will be found to
withstand heat or cold to any extent, while, being non-inflammable, the composition
answers as admirably for stoves and safes as it does as a non-conductor for boilers
and other vessels.
The proportions in which the several substances are mixed mer be as follows •
Mica
Kieselguhr
Fire clay
Coal carbon
60
per cent.
15 per cent.
15
per cent.
10 per cent.
Experience has shown these proportions to be the most suitable, but, of course
they will not answer for all and every purpose to which the composition may be
applied, and it must therefore be clearly understood that the applicant does
not restrict himself to such proportions which must necessarily vary to suit
circumstances.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is ;-
1. A composition consisting of ground mica diatomite kieselguhr fire clay and
mineral carbon substantially as and for the purposes hereinbefore set forth.
2. An improved composition substantially as described.
