Napoléon, Montmartre (Dep¹ de la Seine), in the Empire of France, for
the Invention of "A NEW COMPOSITION APPLICABLE TO THE COATING OR
CORERING OF METALLIC AND NON-METALLIC SUPRAGDS".
PROVISIONAL SPECIFICATION left by the said Marc Antoine François
Mennons at the Office of the Commissioners of Patents, with his
Petition, on the 25th August 1856.
I, MARC ANTOINE FRANÇOIS MENNONS, of 21, Rue. Napoléon, Montmartre
(Dept. de la Seine), in the Empire of France, do hereby declare the nature of
the said Invention for "A NEW COMPOSITION APPLICABLE TO THE COATING OR COVER.
ING OF METALLIC AND NON-METALLIC SURFACES," to be as follows, that is to say :-
This Invention, communicated to me, consists in the combination of the
following materials for producing a composition which is a non-conductor of
heat, suitable for coating and protecting metallic or non-metallic surfaces.
Clay, not liable to crack in drying
2 cwt.
Sawdust, pure, or that which has been used for dyeing,
Ditto, having been employed for purifying oils -
Soot, well sifted
about
22 lbs.

by the said Marc Antoine François Mennons in the Great Seal Patent
Office on the 20th February 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANÇOIS MENNONS, of 21, Rue Napoleon, Montmartre (Departe-
ment de la Seine), in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing date the Twenty-fifth day of August, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Marc Antoine François Mennons, Her special license, that I, the said Marc
Antoine François Mennons, my executors, administrators, and assigns, or such
others as I, the said Marc Antoine François Mennons, my executors, admi-
nistrators, and assigns should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "A NEW COMPOSITION APPLICABLE TO THE COATING OR
COVERING OF METALLIC AND NON-METALLIC SURFACES," communicated to me from

page_text: tion to heated surfaces, such as furnaces, steam boilers, cylinders, or similar
apparatus,may be effected without stopping the work of the machine. When
cold surfaces are to be treated, I add immediately before its application about
one-eighth of its weight of plaster well mixed. When required to cover
funnels or pipes, it is necessary to surround them in spiral form with thin
bands of flax or hemp saturated with the composition itself; this arrangement
assures the perfect adherence of the coatings superposed.
I also construct by means of this composition exterior or interior walls and
partitions. To this end, I form a continuous framework of slight plauks, on
which I apply one or several coats of the compositions till the required thick-
ness and solidity is attained; the surfaces of the last coat should be perfectly
smooth and polished. When dry I-add a coat of unboiled linseed or other oil,
and then paint or varnish in the ordinary way. The application of this com-
position to garden walls is of advantage in accelerating the maturity of the
espalier fruits; it is also advantageously employed in hothouses for main-
taining a regular temperature. On the other hand, its application to ice
.repositories effectually prevents the penetration of heat; in many cases it may
be substituted to ordinary mortars and cements for general binding purposes.
When required to coat surfaces exposed to the direct action of fire, I suppress
the sawdust, vegetable charcoal, or other substances liable to combustion or
change at an elevated temperature. In its application to furnaces in masonry
I diminish by one-fifth the quantity of the inflammable ingredients above
specified. The compound is thus rendered almost incombustible.
In applying this composition to pavements and foundations, I modify it as

page_text: enumerate the various applications of which this composition is susceptible;
suffice it to say, that on steam boilers, and other apparatus of similar nature,
the radiation of heat and oxidation are effectually prevented, thus affording an
immense economy. In its application to building purposes, to the walls of
apartments, it has been proved that while in water its employment gave rise
to an increase of ten degrees centigrade in the temperature, an equivalent
decrease was found to occur in the summer season.
Having now described the nature of my said Invention, and some of the
most obvious methods of applying it, I would have it understood that I do not
limit myself to the precise details and proportions herein-before stated, as the
same may be modified, according to circumstances; but what I claim is, the
preparation of a non-conducting and inoxidable composition of the general
character above described, applicable to the coating of metallic and other
surfaces, and possessing the properties of concentrating acquired caloric on
any given point,preventing its radiation, and in its inodified state resisting the
direct action of fire.
In witness whereof, I, the said Marc Antoine François Mennons, have
hereunto set my hand and seal, this Twentieth day of February, in the
year of our Lord One thousand eight hundred and fifty-seven.
