Year: 1879

page_text: LETTERS PATENT to William Henry Wilkinson, of Birmingham, and George
Wilkinson, also of Birmingham, trading as T. Wilkinson & Sons, Electro
Plate Manufacturers, for the Invention of "COLORED ORNAMENTATION OF
ELECTRO PLATED AND OTHER SUCH LIKE GOODS, AND FOR RENDERING THE
AFORESAID ARTICLES UNTARNISHABLE"
PROVISIONAL SPECIFICATION left by the said William Henry Wilkinson
and George Wilkinson at the Office of the Commissioners of Patents on the
11th October 1879.
WILLIAM HENRY WILKINSON, of Birmingham, and GEORGE WILKINSON, also of
Birmingham, trading as T. Wilkinson & Sons, Electro Plate Manufacturers.
COLORED ORNAMENTATION OF ELECTRO PLATED AND OTHER SUCH LIKE GOODS,
AND FOR RENDERING THE AFORESAID ARTICLES UNTARNISHABLE."
Our Invention has reference to colored ornamentation of electro plated and other
such like goods, and for rendering them untarnishable, and is applicable to articles
manufactured in the usual way from either German silver (otherwise called nickel
silver), sterling silver, Britannia metal, brass, or any other similar alloy or suitable
material.
According to our Invention the article is first electro plated, nickel plated, or
gilt, or partially electro plated and partially gilt, either bright in the usual way
and burnished or frosted white, which will depend upon the design intended to be
produced upon the article; or in the case of such material as may not previously
require electro plating or gilding the surface of the article must be suitably pre-
pared by polishing or other such means to produce a clear surface.
Immediately the electro plating, gilding, or other process is completed we flood
the article all over with a strong coat of varnish, generally made from gums and oil
or other suitable varnish. We then place the article thus varnished in an oven
heated to, say, a temperature of 200 degrees Fahrenheit, which varies according to
the kind of varnish used, but the varnish must be baked on perfectly hard. We
then rub it down with fine rotten stone or pumice stone until the surface is perfectly

page_text: smooth, when it is ready to receive the ornamentation, which we apply by hand
painting, or coloring, or printing, or any such like or known means may be used
for producing any desired effect or design.
The article is then again passed into an oven and the coloring and ornamentation
burnt in until it becomes perfectly hard and secure. It may then be carefully
smoothed over with pumice stone or other similar substance or process to remove
any irregularities from the surfaco and rovarnished, and again exposed to heat in a
suitable oven until the whole surface is perfectly fixed, after which it should be
burnished all over with very smooth fine pumice stone to give the desired gloss or
glaze.
By these means we are able to produce such articles either illuminated in color
and glazed all over or only glazed over the illuminated part, or when preferred
plain we accomplish the glazing without the ornamentation, but in articles
which are glazed all over the glazing has the effect of rendering them perfectly
untarnishable.
Thus we can supply most beautifully ornamented articles at a cheap rate which
will be enduring in their pleasing appearance without the endless cleaning usually
required for such goods.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Henry Wilkinson and George Wilkinson in the Great Seal
Patent Office on the 10th April 1880.

MENTATION OF ELECTRO PLATED AND OTHER SUCH LIKE GOODS, AND FOR RENDERING
THE AFORESAID ARTICLES UNTARNISHABLE."
Our Invention has reference to coloured ornamentation of electro plated and
other such like goods, such as wares and jewellery, and for rendering them
untarnishable, and is applicable to articles manufactured in the usual way from
either German silver, otherwise called (nickel silver, sterling silver, Britannia
metal, brass, or any other similar alloy or suitable material.
According to our Invention the article is first electro plated, nickel plated, or
gilt, or partly plated and partially gilt, either bright in the usual way and burnished
or frosted white, which will depend upon the design intended to be produced upon
the article; or in the case of such material as may not previously require electro
plating or gilding the surface of the article must be suitably prepared by polishing
or other such means to produce a clear surface.
Immediately the electro plating, gilding, or other process is completed we flood
the article all over with a strong coat of varnish, generally made from gums and
oils, or other suitable varnish. We then place the article thus varnished in an
ovan heated to, say, a temperature of 200 Farenheit, which varies according to
the kind of varnish used, but the varnish must be baked on perfectly hard. We

page_text: then rub it down with fine rotten stone or pumice stone until the surface is perfectly
smooth, when it is ready to receive the ornamentation, which we apply by hand
painting, or colouring, or printing, or any such like known means may be used for
producing any desired effect or design.
The article is then again passed into an oven and the colouring and ornamentation
burnt in until it becomes perfectly hard and secure. It may then be carefully
smoothed over with pumice stone or other similar substance or process to remove
any irregularities from the surface and revarnished, and again exposed to heat in a
suitable oven until the whole surface is perfectly fixed, after which it should be
burnished or polished all over with very smooth fine pumice stone or rotten stone
to give the desired gloss or glaze.
By these means we are able to produce such articles either illuminated in colour
and glazed all over or only glazed over the illuminated part, or when preferred
plain we accomplish the glazing without the ornamentation, but in articles
which are glazed all over the glazing has the effect of rendering them perfectly
untarnishable.
Thus we can supply most beautifully ornamented articles at a cheap rate which
will be enduring in their pleasing appearance without the endless cleaning usually
required for such goods.
Articles glazed and ornamented as before described we propose calling "Pelican
Ware."
Having now described the nature of our said Invention, and the manner of
carrying the same into practice, we would have it understood that we claim the
manufacture of coloured and untarnishable electro plated and other goods, sub-
stantially in the manner herein before described.
In witness whereof, we, the said William Henry Wilkinson and George
Wilkinson, have hereunto set our hands and seals, this Ninth day of
April, in the year of our Lord One thousand eight hundred and eighty.
