ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent. ‘IMPROVEMENTS IN THE MANUFACTURE OF JEWELLERY, BUTTONS,
COMBS, AND OTHER ARTICLES." [A communication from abroad by Messieurs Veit
and Nelson, of 11, Rue Bergère, Paris, France.]
This Invention has for object a system of manufacturing jewellery and other
articles by employing galvanic baths chiefly to be used for jewellery of plain or
cut glass or enamel melted or mounted on metallic wire, tubes, or plates, and for
other articles of which the material is mounted the same way.
Up to the present time several means have been employed in the manufacturing of
jewellery and other articles for fastening upon the metallic back pieces or glass or
enamel melted or mounted on metallic wires, tubes, or plates, and one of the last
kind employed is the rivetting or ordinary soldering of the metal wires, tubes, or
plates on the reversed side of the metallic back.
According to this Invention the following system is to be used for the manu-
facturing of jewellery, buttons, combs, &c., of plain or cut glass or enamel melted
or mounted on metallic wires, tubes, and plates :-
The pieces of metal wire on which the pieces of glass or enamel are melted or
mounted, and which by their connection are destined to compose the article to be
manufactured, are put through the holes of the pierced metallic band, which may
be of copper or any other suitable metal,

page_text: The above mentioned object put through the holes of the metallic back, as
described, and closely fittod, as the size of the holes are nearly the thickness of
the wires, is put into a galvanic bath such as is generally used for gilding, silvering,
or other purposes, the composition of the bath however changing according to what
metal is to be employed. In all cases the sediment of the metals which, under the
action of the electric current, takes place will fill up the space existing between the
metallic wire and the metallic back, and keeps those two objects firmly united, and
in all such cases these pieces of glass and wire representing the article to bo manu-
factured are, according to this system, firmly fixed upon the metallic backs.
The right is reserved to change the composition of the galvanic bath employed
in order to produce sediment of any kind of metal; furthermore, is reserved the
use of this system for every article besides jewellery to effect a connection of the
different parts of which it is composed.

ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent. "IMPROVEMENTS IN THE MANUFACTURE OF JEWELLERY, BUTTONS,
COMBS, AND OTHER ARTICLES." A communication from abroad by Messieurs Voit
and Nelson, of 11, Rue Bergère, Paris, France.
This Invention has for object a system of manufacturing jewellery and other
articles by employing galvanic baths chiefly to be used for jewellery of plain or
cut glass or enamel melted or mounted on metallic wire, tubes, or plates, and for
other articles of which the material is mounted the same way.
Various means have been employed in the manufacturing of jewellery and other
articles for fastening upon the metallic back pieces of glass or enamel melted or
mounted on metallic wires, tubes, or plates; and one of the most recont methods
employed consists in rivetting or ordinary soldering the metal wires, tubes, or plates
on the reverse side of the metallic back.
According to this Invention the following system is to be used for the manu-
facturing of jewellery, buttons, combs, &c., of plain or cut glass or enamel melted or
mounted on metallic wires, tubes, and plates:-
The pieces of metal wire on which the pieces of glass or enamel are melted or
mounted, and which by their connection are destined to compose the article to be
manufactured, are put through the holes of the pierced metallic band, which may
be of copper or any other suitable metal. The above mentioned object after being
put through the holes of the metallic back, as described, and closely fitted, for
which purpose the holes are made of nearly the same size as the wires, is put into
a galvanic bath such as is generally used for gilding, silvering, or other purposes,
the composition of the bath being however varied according to the kind of metal
employed. In all cases the sediment of the metals which, under the action of the
electric current, takes place will fill up the space existing between the metallic
wire and the metallic back, and keeps those two objects firmly united, and in all
such cases these pieces of glass and wire representing the article to be manufactured
are, according to this system, firmly fixed upon the inetallic backs.
The right is reserved to change the composition of the galvanic bath employed
in order to produce a sediment of any kind of metal.
Having described the nature of the said Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the herein-
before in part recited Letters Patent is,-
1st. The process for fastening solidly the different parts of any article to be
manufactured by the use of a galvanic bath, as above described and for the
purposes set forth.
End. The application of the above described process to the manufacture of
jewellery of glass, enamel, or any other material melted or mounted on metallic
wires, tubes, or plates, and also to the manufacture of other articles, as above
described and for the purposes set forth.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Thirteenth day of August, in the year of our Lord
