IMPROVEMENTS IN THE MANUFAC- TURE OF ARTIFICIAL STONE FOR BUILDING PURPOSES
Year: 1860

page_text: LETTERS PATENT to James Joseph Wheble, of Reading, in the County of
Berks, Esquire, for the Invention of "IMPROVEMENTS IN THE MANUFAC-
TURE OF ARTIFICIAL STONE FOR BUILDING PURPOSES."
Sealed the 4th June 1861, and dated the 7th December 1860.
PROVISIONAL SPECIFICATION left by the said James Joseph Wheble
at the Office of the Commissioners of Patents, with his Petition, on the
7th December 1860.
I, JAMES JOSEPH WHЕBLE, of Reading, in the County of Berks, Esquire,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF ARTIFICIAL STONE FOR BUILDING PURPOSES," to be as follows:-
This Invention relates to the manufacture of artificial stone in a more
economic manner than has been adopted heretofore. I propose taking ordinary
dry rubbish, sand, gravel, and shingle, and mixing the same with Bridgewater or
other similar lime, such as blue lias or any other description of suitable lime
after being ground, when the whole is stirred and thoroughly mixed (the lime
being in a hot state), water is to be added; it is then to be placed in moulds
and frames and moulded into any desired form or device, the moulds being first
lubricated; the material leaves them in all cases with a clear plain external
surface, and does not require cementing or facing again.
The proportions in which I propose mixing the materials, and which I have

page_text: found answer well in practice, are, one part of lime to three parts of the other
materials. Any mineral color may be mixed with them, or external coloring
may be applied, the composition being well adapted to receive either or both.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Joseph Wheble in the Great Seal Patent Office on
the 7th June 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
JOSEPH WHEBLE, of Reading, in the County of Berks, Esquire, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of December, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Joseph. Whebic, Her special licence that J, the said James Joseph
Wheble, my executors, administrators, and assigns, or such others as I,
the said James Joseph Wheble, 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 ARTIFICIAL STONE FOR BUILDING PUR-
FOSES," upon the condition (amongst others) that I, the said James Joseph
Wheble, 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 James Joseph Wheble, 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, that is to say:-
This Invention relates to the manufacture of artificial stone in a more
economic manner than has been adopted heretofore.
In order to explain my said Invention as completely as possible, I now pro-

page_text: ceed to describe the best means I am acquainted with for carrying the same
into practical effect, as follows:-
I take ordinary dry rubbish, sand, gravel, and shingle, and mix the same
with Bridgewater or other similar lime after being ground, when the whole is
to be stirred and thoroughly mixed; water is now to be added and well incor-
porated with the material, which is to be placed in suitable moulds and frames
and moulded into any desired form or device; the moulds being first lubri
cated, the material leaves them in all cases with a clear plain external surface,
and does not require cementing or facing again.
The proportions in which the materials are to be mixed, and which I have
found to answer well in practice, are, one part of lime to three parts of the
other materials. Any mineral color may be mixed with them, or external
coloring may be applied, the composition being well adapted to receive either
or both.
Having now described the nature of my said Invention of "Improvements
in the Manufacture of Articial Stone for Building Purposes," and the manner
in which the same is to be performed, I would remark in conclusion, that I do
not confine myself to the exact proportions herein mentioned, as they may be
slightly varied according to circumstances; but what I claim as my Invention
intended to be secured to me by the herein in part recited Letters Patent is,
the manufacture of artificial stone by the admixture of the within-named
materials in the manner herein fully described for the purposes set forth.
In witness whereof, I, the said James Joseph Wheble, have hereunto set
my hand and seal, this Twenty-eighth day of May, in the year of our
Lord One thousand eight hundred and sixty-one.
