IMPROVEMENTS IN THE MANU- PICTURE OF BUILDING MATERIALS AND OTHER SIMILAD PRODATO " PROAL
Year: 1874

page_text: LETTERS PATENT to Joseph Deléon, of Boulevard de Strasbourg,
No. 23, at Paris, for the Invention of "IMPROVEMENTS IN THE MANU-
PICTURE OF BUILDING MATERIALS AND OTHER
SIMILAD PRODATO "
PROVISIONAL SPECIFICATION left by the said Joseph Deléon at the
Office of the Commissioners of Patents, with his Petition, on the
10th February 1874.
I, JOSEPH DELÉON, of Boulevard de Strasbourg, No. 23, at Paris, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF BUILDING MATERIALS AND OTHER SIMILAR PRODUCTS," to
be as follows:-
My Invention consists in the instantaneous hydraulic aggregation of
materials for building and constructive purposes by the mixture of
powdered limestone and sand with magnesia, chloride of magnesium,
and carbonate of soda also in a pulverized condition.

page_text: My process dispenses with any necessity for firing or baking, and
enables the ceramic products to be employed immediately on its com-
pletion.
I can manufacture by my process, in which carbonate of soda plays'
more particularly the part of the hydraulic agent, products of various
kinds, such as bricks, tiles, artificial stones, imitation marbles, lithographic
stones, and others.
Although I desire to be at liberty to vary in each mixture the
respective proportions of the three chemical substances above given,
magnesia, chloride of magnesium, and carbonate of soda, so as to render
them suitable for the object to be produced, yet I proceed to give some
formulas which I have found to work well in practice as illustrations
and examples of my process.

The pulverized mixture is effected in the following manner :- -The
limestone, sand, and magnesia are first mixed, and then the chloride of
magnesium is added, after which the mixture is well stirred and the
carbonate of soda lastly added. The whole mixture after being well
mingled is submitted to moulding, pressure, or other ordinary manipu-
lation.
The chemical substances, namely, the magnesia, the chloride of
magnesium, and the carbonate of soda, immediately react upon one
another and the hydraulic aggregation is, so to speak, instantaneous,
which permits the immediate employment of the solid brick, which thus
manufactured I have found will support a pressure of over 50 tons.
When it is desired to manufacture tiles, paving blocks, drainage pipes,
and similar articles, the three chemical substances are employed in the
same relative proportions to one another as are given above, but are
augmented by one-fourth in relation to the powdered limestone and
sand.

limestone. Lithographic stones may be obtained by the following
mixture:

above obtain materials for building and constructions of all kinds in the
arts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Deléon in the Great Seal Patent Office
on the 8th August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
DELÉON, of Boulevard de Strasbourg, 23, at Paris, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of February, 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 Joseph Deléon, Her special licence
that I, the said Joseph Deléon, my executors, administrators, and
assigns, or such others as I, the said Joseph Deléon, my executors,
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 "IMPROVEMENTS
IN THE MANUFACTURE OF BUILDING MATERIALS AND OTHER SIMILAR PRODUCTS," upon
the condition (amongst others) that I, the said Joseph Deléon, 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
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Deléon, 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 :-
My Invention consists in the instantaneous hydraulic aggregation of
materials for building and constructive purposes by the mixture of

page_text: powdered limestone and sand with magnesia, chloride of magnesium,
and carbonate of soda also in a pulverized condition.
My process dispenses with any necessity for firing or baking, and
enables the ceramic products to be employed immediately on its com-
pletion.
I can manufacture by my process, in which carbonate of soda plays
more particularly the part of the hydraulic agent, products of
various kinds, such as bricks, tiles, artificial stones, imitation marbles,
lithographic stones, and others.
Although I desire to be at liberty to vary in each mixture the
respective proportions of the three chemical substances above given,
magnesia, chloride of magnesium, and carbonate of soda, so as to render
them suitable for the object to be produced, yet I proceed to give some
formulas which I have found to work well in practice as illustrations and
examples of my process.

The pulverized mixture is effected in the following manner :-The
limestone, sand, and magnesia are first mixed, and then the chloride of
magnesium is added, after which the mixture is well stirred, and the
carbonate of soda lastly added. The whole mixture after being well
mingled is submitted to moulding pressure or other ordinary manipu-
lation.
The chemical substances, namely, the magnesia, the chloride of
magnesium, and the carbonate of soda, immediately react upon one
another, and the hydraulic aggregation is so to speak instantaneous,
which permits the immediate employment of the solid brick, which thus
manufactured I have found will support a pressure of over 50 tons.
When it is desired to manufacture tiles, paving blocks, drainage
pipes, and similar articles, the three chemical substances are employed
in the same relative proportions to one another as are given above, but

page_text: Car Party by micans of the Chemical agents so often mentioned
above obtain materials for buildings and constructions of all kinds in the
arts.
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
use of magnesia, chloride of magnesium, and carbonate of soda in
combination with limestone, sand, and similar substances, in order to
manufacture bricks, tiles, artificial stones, imitation marbles, lithographic
stones, and other such articles for building and other purposes, sub-
stantially as herein-before described.
In witness whereof, I, the said Joseph Deléon, have hereunto set
my hand and seal, this Twenty-ninth day of July, One thousand
eight hundred and seventy-four.
