Year: 1858

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, E.C., Editor of the Mechanics' Magazine and
Patent Agent, for the Invention of "AN IMPROVEMENT IN PLATING AND
GILDING FORKS, SPOONS, AND OTHER METAL ARTICLES."-A communication
from Messieurs de Sauvigny, residing at Paris.
Sealed the 14th June 1859, and dated the 16th December 1858.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on
the 16th December 1858.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, E.C., Editor of the Mechanics' Magazine and Patent Agent, dó
hereby declare the nature of the said Invention for "AN IMPROVEMENT IN
PLATING AND GILDING FORKS, SPOONS, AND OTHER METAL ARTICLES," (commu-
nicated to me by Messieurs de Sauvigny, residing at Paris,) to be as
follows:-
According to the method usually followed in electro-plating and gilding,
a uniform coating is laid on every portion of the article silvered or gilt. Now,.
in many articles which are subjected to more wear at some parts than at others,
as, for instance, the prongs of forks, the bowls of spoons, &c., it is desirable
to obtain a thicker coating at those parts. In order to effect this object I
take any article after having been uniformly coated by the aid of the galvanic
bath, then heat it, and by affinity of metal for metal solder on to those parts
requiring a thicker coating as many layers of leaf silver or gold' as may be
necessary to produce the thickness desired.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, E.C.,
Editor of the Mechanics' Magazine and Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of December, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Archibald Brooman, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such others
as I, the said Richard Archibald Brooman, 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 Inven-
tion for "AN IMPROVEMENT IN PLATING AND GILDING FORKS, SPOONS, AND OTHER
METAL ARTICLES," (communicated to me by Messieurs de Sauvigny, residing at
Paris,) upon the condition (amongst others) that I, the said Richard
Archibald Brooman, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 I, the said Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
According to the method usually followed in electro-plating and gilding, a
uniform coating is laid on every portion of the article, silvered or gilt. Now,
in many articles which are subjected to more wear at some parts than at
others, as, for instance, the prongs of forks, the bowls of spoons, &c., it is
desirable to obtain a thicker coating at those parts. In order to effect this
object I take any article, after having been uniformly coated by the aid of the
galvanic bath, then heat it, and by affinity of metal for metal solder on to-
those parts requiring a thicker coating as many layers of leaf silver or gold

page_text: as may be necessary to produce the thickness desired. When a spoon, fork,
or other article is partially worn, without ungilding or unsilvering the whole
article, those parts only where the defects exist need be covered.
an article which has been previously coated by the ordinary galvanic bath in
parts it is heated to about 500° centigrade (932° Fahrenheit), silver or gold
leaf is then placed on the parts to be covered. The spoon, fork, or other
article can be burnished with a brush, feather, agate, or other usual burnishing
tool.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim the improvement
in plating and gilding forks, spoons, and other metal articles herein-before
described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Fifteenth day of June, One thousand
eight hundred and fifty-nine.
K. A. BROUMAN. (L.S.)
