"IMPROVEMENTS IN THE MANUFACTURE OF METAL ARTICLES
HAVING SURFACE ORNAMENTATION." A communication from abroad by Otto von
Wiersbitzky, of Leipzic, Germany.
This Invention has for object to produce articles in metal having surface
ornamentation of inlaid work by means of electrotyping.
In carrying out the Invention a copper plate or other surface which may be
metalised by graphite or any other material used by electro-metallurgists. The
outline of the pattern which is to bo formed by incrustation or inlaid work is
traced out upon the prepared surface, and the pieces to be incrusted, consisting of
metal patterns, stones of any kind, glass, mother of pearl, tortoise shell, ivory, jet,
amber, wood, or any imitations of these materials, as made of india rubber, celluloid,
and so forth, are shaped by cutting, stamping, filing, sawing, or in any other suitable
manner, according to the position and space they are severally to occupy in tho
design. This done, that surface of each piece which is intended to appear in the
finished work is pasted, by means of varnish or other appropriate adhesive stuff, to
the bed plate on which the pattern has already been outlined, each, of course, in
that place which it is to occupy in the design. The surface of this plate forming
the base, on which the pieces to be incrusted are now pasted, and of which the back
is to be seen, is now prepared in the manner known to every metallurgist, so as to
secure a metallic deposit on the pieces for embedding same.
When the plate surface is thus prepared it is immersed in a solution of sulphate
of copper or whatever other appropriate metallic solution is desired, and after being
attached to the positive pole of a galvanic battery the metal contained in the

page_text: solution will be deposited and spread over the whole prepared plate and cover and
envelop all the pasted pieces in bed of metal.
When the metallic deposit has acquired the desired thickness it is detached
from the base plate, the varnish or glue giving way, and on turning it over there is
found a surface exactly corresponding to the base plate, but in which all the pasted
pieces forming the pattern or design are inlaid in such an exact and nice manner as
it is impossible to effect by any manner of process applied heretofore.
This inlaid surface, for instance, of a table top, may then be still more ornamented
by engraving, gilding, silver-plating, or in any other manner desired.
By like process may be made tablets, panels for rooms, furniture and so forth,
covers of albums or books, box lids or sides, and articles of any shape and kind.

This Invention has for object to produce articles in metal having surface
ornamentation of inlaid work by means of electrotyping.
In carrying out the Invention a copper plate or other surface which may be
metalised by graphite or any other material used by electro-metallurgists.
The outline of the pattern which is to be formed by incrustation or inlaid work
is traced out upon the prepared surface, and the pieces to be incrusted, consisting
of metal patterns, stones of any kind, glass, mother of pearl, tortoise shell, ivory,
jet, amber, wood, or any imitation of these materials, as made from india rubber,
celluloid, and so forth, are shaped by cutting, stamping, filing, sawing, or in any
other suitable manner, according to the position and space they are severally to
occupy in the design. This done, that surface of each piece which is intended to
appear in the finished work is pasted, by means of varnish or other appropriate
adhesive stuff, to the bed plate on which the pattern has already been outlined,
each, of course, in that place which it is to occupy in the design. The surface of
the plate forming the base, on which the pieces to be incrusted are now pasted,
and of which the back is to be seen, is now prepared in the manner known to
every metallurgist, so as to secure a metallic deposit on the pieces for embedding
same.
When the plate surface is thus prepared it is immersed in a solution of sulphate
of copper, or whatever other appropriate metallic solution is desired, and after being
attached to the positive pole of a galvanic battery the metal contained in the
solution will be deposited and spread over the whole prepared plate, and cover and
envelop all the pasted pieces in a bed plate of metal.
When the metallic deposit has acquired the desired thickness it is detached from
the base plate, the varnish or glue giving way, and on turning it over there is
found a surfaco exactly corresponding to the base plate, but in which all the pasted
pieces forming the pattern or design are inlaid in such an exact and true manner as
it is impossible to effect by any manner or process applied heretofore.
This inlaid surface, for instance, of a table top, may then be still more ornamented
by engraving, gilding, silver plating, or in any other manner desired.
By like process may be made tablets, panels for rooms, furniture and so
forth, covers of albums or books, box-lids or sides, and articles of any shape and
kind.
Having now described the nature and particulars of the said Invention, I
claim,
The improvements in the manufacture of metal articles having surface
ornamentation of inlaid work by so called electro-typing process, as and for the
purpose herein set forth.
In witness whereof, I, the said Walter Alfred Barlow, have hereunto set my
hand and seal, this Twentieth day of December, in the year of our Lord
One thousand eight hundred and eighty.
