A NEW AND IMPROVED MODE OF INLAYING GOLD AND OTHER METALS IN GLASS, AND IN A COMPOSITION SUITABLE FOR THE MANUFACTURE OF JEWELLERY AND OTHER ORNAMENTS, BUTTONS, AND OTHER SIMILAR ARTICLES
Year: 1863

page_text: LETTERS PATENT to William Charles Wild and James Henry Randel,
both of Birmingham, in the County of Warwick, Dealers in Precious
Stones, for the Invention of "A NEW AND IMPROVED MODE OF INLAYING
GOLD AND OTHER METALS IN GLASS, AND IN A COMPOSITION SUITABLE FOR THE
MANUFACTURE OF JEWELLERY AND OTHER ORNAMENTS, BUTTONS, AND OTHER
SIMILAR ARTICLES."
Sealed the 11th September 1863, and dated the 18th March 1863.
PROVISIONAL SPECIFICATION left by the said William Charles Wild
and James Henry Randel at the Office of the Commissioners of
Patents, with their Petition, on the 18th March 1863.
We, WILLIAM CHARLES WILD and JAMES HENRY RANDEL, both of
Birmingham, in the County of Warwick, Dealers in Precious Stones, do
hereby declare the nature of the said Invention for "A NEW AND IMPROVED
MODE OF INLAYING GOLD AND OTHER METALS IN GLASS, AND IN A COMPOSITION
SUITABLE FOR THE MANUFACTURE OF JEWELLERY AND OTHER ORNAMENTS, BUTTONS,
AND OTHER SIMILAR ARTICLES," to be as follows, that is to say :-
Our Invention consists of the mode in which metals are inlaid in glass and
in the composition (herein-after described) by our process and the manner of

page_text: preparing the said composition for the inlaying of such metals. When we
desire to inlay gold or any other metal in glass, we place the metal to be so
inlaid within a mould, which is then placed at one end of a pair of pinching
pliers, and having melted sufficient glass to fill the mould, we compress the
pliers, and the metal remains imbedded within the glass, which is then annealed,
and is afterwards ready for cutting and polishing.
When we desire to inlay gold or any other metal in the composition, we
first prepare the said composition by taking about four parts of glass and two
parts of enamel, which, after being well pounded and mixed in a mortar, is
placed in a copper mould with the metal to be inlaid at the bottom of the
mould; we then place the mould on a copper plate (on which is spread a thin
layer of plaster of Paris), and the plate with the mould on it is then placed in
an enamelling stove over a coke fire until the whole is well fused; it is then
annealed, and when taken out of the mould is ready for cutting and polishing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Charles Wild and James Henry Randel in the
Great Seal Patent Office on the 15th September 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
CHARLES WILD and JAMES HENRY RANDEL, both of Birmingham, in the
County of Warwick, Dealers in Precious Stones, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said William Charles Wild and James Henry Randel, Her
special licence that we, the said William Charles Wild and James Henry
Randel, our executors, administrators, and assigns, or such others as we,
the said William Charles Wild and James Henry Randel, our 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 ex-
pressed, 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 AND IMPROVED MODE OF INLAYING GOLD AND
OTHER METALS IN GLASS, AND IN A COMPOSITION SUITABLE FOR THE MANUFACTURE
OF JEWELLERY AND OTHER ORNAMENTS, BUTTONS, AND OTHER SIMILAR ARTICLES,"

page_text: upon the condition (amongst others) that we, the said William Charles Wild
and James Henry Randel, our executors or administrators, by an instrument in
writing under our, 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 we, the said William Charles Wild and James
Henry Randel, do hereby declare the nature of our 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):-
Our Invention consists of the mode or manner in which metals are inlaid in
glass and in the composition (herein-after described) by our process, and the
manner of preparing the said composition for the inlaying of such metals.
When we desire to inlay gold or any other metal in glass, we place the metal
to be so inlaid within a mould, which is then placed at one end of a pair of
pinching pliers, and having melted sufficient glass to fill the mould we com-
press the pliers, and the metal remains imbedded within the glass, which is
then annealed, and is afterwards ready for cutting and polishing.
The glass most suited for our purpose we find to be the kind known as
Bohemian glass, as this melts at a lower heat and takes a better polish than
other descriptions of glass, but when this is not to be obtained, or when we
desire to produce a cheaper article, we use the common kind of English
glass.
When we desire to inlay gold or any other metal in the composition before
mentioned, we first prepare the said composition by taking about four parts of
glass and two parts of enamel, which, after being well pounded and mixed in a
mortar, is placed in a copper mould with the metal to be inlaid at the bottom
of the mould; we then place the said mould on a copper plate (on which is
spread a thin layer of plaister of Paris), and the plate with the mould on it is
then placed in an enamelling stove over a coke fire until the whole is well
fused; it is then annealed, and when taken out of the mould is ready for
cutting and polishing.
Having now particularly described and ascertained the nature of our Inven-
tion, and the manner whereby the same is or may be performed, we desire it
to be understood that we do not limit ourselves to. the precise details herein
named, as the same may be varied without departing from the nature of our
said Iuvention; but what we claim and desire to be secured to us by the

page_text: herein-before in part recited Letters Patent is, substantially the mode or
manner of inlaying gold and other metals in glass, and in a composition as
herein-before described and set forth.
In witness whereof, we, the said William Charles Wild and James
Henry Randel, have hereunto set our hands and seals, this Twelfth day
of September, in the year of our Lord One thousand eight hundred and
sixty-three
