in the County of Middlesex, for the Invention of "IMPROVED MEANS
OF, AND COMPOSITIONS FOR PRESERVING WOOD AND OTHER MATERIALS AND :
PROVISIONAL SPECIFICATION left by the said. Cristoforo Muratori
at the Office of the Commissioners of Patents, with his Petition,
on the 14th March 1874.
I, CHRISTOFORO MURATORI, of No. 29, Burton Crescent, in the County
of Middlesex, do hereby declare the nature of the said Invention. for
"IMPROVED MEANS OF AND COMPOSITIONS FOR PRESERVING WOOD AND OTHER
MATERIALS AND STRUCTURES, AND FOR RENDERING THEM FIREPROOF," to be as"
follows:-
The objects of this Invention are, the preservation of wood and other..
materials and structures and the production of fireproof compositions,
and consists mainly in the combination with wood, iron, or other
metals, stone, glass, coal, and the powders of the same substances, such

page_text: as can be used in the construction and decoration of buildings, bridges,
ships, boats, carriages, also artistic and other furniture and work, boilers,
girders, cylinders, pipes, and safes, and for all purposes for which the
above bodies in which fireproofing and preserving are required. The
composition is made of the following ingredients and proportions:-
Waste cuttings and scrapings of.-
girders, cylinders, pipes, and safes, and for all purposes for which the
above bodies in which fireproofing and preserving are required. The
composition is made of the following ingredients and proportions:-
Waste cuttings and scrapings of,-
Skins
Alum
Gum

These ingredients are to be mixed and boiled until four parts of the
liquid are evaporated, and it is thereby reduced to 1th in quantity, liquid
measure. It may then be well mingled with powder or particles of the
bodies above mentioned, according to the substitute désired, viz., the
powder of talc for white stone powder, of marble for marbles, bronze
and other metals for their metals, wood for wood, glass for glass, and
so on.
For the construction of large works I use pieces of the above
substances cut into any suitable lengths and sizes in combination with
their powders, so that if I wish to join pieces of wood I use powder of
wood, if iron powder of iron, and so on, and thus I obtain a homogeneous
substance of each of such materials and of a strength superior to the
natural strength of the same substances. This composition renders
uninflammable works in which it is thus used, preserves iron from
oxidation, produces a great economy of fuel in boilers and pipes by
preventing the radiation of heat, and renders safes much less accessible
to heat. It attaches itself to all the above substances and also to india-
rubber, gutta percha, canvas, and any sort of cloth.
To make or cover ceilings, floorings, fronts of houses, cylinders, ships,
and boats, carriages, girders, boilers, and other constructions in which I
want to use wood I use natural wood, and in particular pieces of wood
united, and to render them uninflammable and to acquire in them greater
strength I place them in a cold bath of alum for 24 hours and then
unito them with my composition of such a size as is required.

In pursuance of the conditions of the Letters Patent,
filed by the said Cristoforo Muratori in the Great Scal Patent
Office on the 14th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CRISTOFORO
MURATORI, of No. 29, Burton Crescent, in the County of Middlesex;
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing date the Fourteenth day of March, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Cristoforo Muratori, Her special, licence that
I, the said Cristoforo Muratori, my executors, administrators, and
assigns, or such others as I, the said Cristoforo Muratori, my exccutors,
administrators, 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 "IMPROVED MEANS
OF AND COMPOSITIONS FOR PRESERVING WOOD AND OTHER MATERIALS AND.
STRUCTURES, AND FOR RENDERING THEM FIREPROOF," upon the condition
(amongst others) that I, the said Cristoforo Muratori, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Cristoforo Muratori, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
The objects of this Invention are the preservation of wood and other
materials and structures, and the production of fireproof compositions,"
and it consists mainly in the combination of such composition with
wood, iron, or other metals, stone, glass, coal, and the powders of the
same substances such as can be used in the construction and decorations.

page_text: of buildings, bridges, ships, boats, carriages, also artistic and other
furniture and work, boilers, girders, cylinders, pipes, and safes, and for
all purposes for which the above bodies are available in which fireproofing
and preserving are required. This composition is made of the following
ingredients, and in some cases of the following proportions:-Waste
outtings and soraninės of

Or bundings, bridges, smps, boats, carriages, also artistic and
furniture and work, boilers, girders, cylinders, pipes, and safes, and for
all purposes for which the above bodies are available in which fireproofing
and preserving are required. This composition is made of the following
ingredients, and in some cases of the following proportions:-Waste

These ingredients are mixed and boiled until four parts. of the. liquid
are evaporated and thereby reduced to the in quantity, liquid measure.
It is then well mingled with powder or particles of the bodies above
mentioned, according to the substitute desired, namely, the powder of.
talc for white stone powder, of marble for marbles, bronze and other
metals for their metals, wood and powder for wood, glass for glass, and
so on.
For the construction of large works I use pieces of the above
substances cut into any suitable lengths and sizes in combination with
their powders, so that if I wish to join pieces of wood I use powder of
wood, if iron powder of iron, and so on, and thus I obtain homogeneous
substances of each of such materials, and of a strength superior to the
natural strength of the same substances. This composition renders
uninflammable works in which it is thus used, preserves iron from
oxidation, produces a great economy of fuel in boilers and pipes by
preventing the radiation of heat, and renders safes much less accessible
to heat. It attaches itself easily to all the above substances and also to
india-rubber and gutta percha.
'To make or cover ceilings, floorings, fronts of houses, cylinders, ships
and boats, carriages, girders, boilers, and other constructions in which I
want to use wood I use natural wood, and in particular pieces. of wood
united, and to render them uninflammable and to acquire in them greater
strength I place them in a cold bath of alum for 24 hours and then
unite them with my composition of such a size as is required.
The proportions of the foregoing ingredients forming the composition
can be varied to suit the different purposes, as before explained, to
which the composition has to be applied or employed.

page_text: The following proportions of ingredients are also applicable for the
purpose, according to my Invention, as will be gathered from the method
or process of amalgamating them to form a composition as below.
1 pound by weight of waste cuttings and scrapings of skins is boiled in
20 lbs. of water until it is reduced to 5 lbs. I then add 6 ounces of alum
and 1 oz. of gum. Instead of waste cuttings I can substitute glue.
When this composition is made I mix it with sawdust, powder of metal,
and of the other substances above mentioned until a cold paste of the
consistency of wax is produced which can be moulded in moulds either
of metal, plaster, or gelatine. The paste thus made can be used for
covering wood, stone, and the substances above mentioned, to which it
attaches completely, and pieces of wood can be connected by it so as to
act as a cold gluc, as herein-before set forth.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim, the
combination of ingredients above referred to and the method of preparing
them to form compositions for preserving wood and other materials and
structures, and for rendering them fireproof, as described.
In witness whereof, I, the said Cristoforo Muratori, have hereunto
set my hand and seal, this Fourteenth day of September, One
thousand eight hundred and seventy-four.
CRISTOFORO MURATORI. (L.S.)
