OTHER SIMILAR.USES."-A communication from abroad by Jean Baptiste

Sealed the 7th August 1862, and dated the 12th February 1862.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the, Office of the Commissioners of Patents, with his Petition, on
the 12th February 1862.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PREPARING AND ORNAMENTING CAST IRON, AND
METALS IN ORDER TO FIT THEM FOR ARTICLES OF FURNITURE, AND DECORATION,
AND OTHER SIMILAR USES," (communicated to me from abroad by Jean Baptiste.
Godin, of Guise, France,) to be as follows:-
The chief object of the Invention is to render cast iron suitable for articles
of furniture free from all liability to oxidation, and to ornament it by the
application of the coloring, and decorative processes used to ornament
ceramic wares. In order to apply the ornamentation it is necessary the metal
should receive a preparation, that is, it must be covered by a vitrified varnish,
upon which the ornamentation or decoration is applied; I obtain this coating

page_text: in all colors by employing in a dry state as hereafter stated opaque enamels
in a proper state of fusibility for spreading over the metal together with
coloring oxides used in vitrifiable colors. By this Invention imitations of
marble, precious stones, various woods, are among those obtained on cast iron
and other metals.
The method of proceeding is as follows:-The pieces of metal, say, cast
iron, are cleaned, and washed and placed in a furnace or muffle, heated to a
red heat, as soon as the metal has attained the same temperature as the furnace
it is withdrawn, and. the enamel is sifted on it.. When the metal is evenly
covered with the enamel, it is again inserted in the furnace, where it is kept
until the enamel forms a beautiful glaze. Uncolored enamels produce by
combining with the oxide of iron, which forms on the surface of the heated
metal a vitrification having the appearance of black marble. When cool the
enamelled surfaco may be ornamented in colors with a brush as practised on
glass and pottery. Imitations of marbles, woods, and stones. of different.colors
are also produced by a brush in. any design according to the taste and skill
of the artist. Gilding and silvering are applied on. the. enamel,as. on glass
and porcelain, but in order to heighten the effects produced as before described,
I apply metallic and other lustres varied by mixtures. of. colors. with the
metallic lustres, or by the action of smoke on the. lustres. After the colors
and lustres have been applied the enamelled metal, is again placed in the
furnace. The lustres which are developed by the action of gas or smoke on
colors containing oxide of-silver-permit of a-more-extended application than
has hitherto been obtained on porcelain or pottery, and this is owing to being
enabled to remove and examine the metal while red without its being liable.
to a draught of air breaking it as would be the case with porcelain To
facilitate the operation of smoking the lustres as the pieces issue.from the
muffle they are placed, in a closed vessel, where, by means of a tap, the wood,
smoke, gas, or steam is introduced... This tap is placed, in communication.
with a smoke, or gas receiver by means of a caoutchouc tube, so that, when,
the action is only required on one part an attendant directs the gas, to that
part. The furnaces, or muffles, are made in, proportion, to the size of the
articles to be manufactured with a door at each end. To avoid as much
as possible loss of heat, these. doors are made of fire-brick. held in, a
metal frame. In order, that, the doors may open and close with facility, they
are fitted and work in slides placed at the sides of the entrance, they are each
suspended at the end of a lever, at the other extremity of which there is a
counterweight.

by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 12th August 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
5 ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of February, in the year of our
Lord One thousand eight hundred, and sixty-two, in the twenty-fifth year of
0 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
Rich 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
5 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 Invention
for "IMPROVEMENTS IN PREPARING AND ORNAMENTING CAST IRO AND OTHER METALS,
IN. ORDER TO FIT THEM FOR ARTICLES OF FURNITURE, AND DECORATION, AND OTHER
O SIMILAR USES," (communicated from abroad by Jean Baptiste Godin, of Guise,
France,) upon the condition (amongst others) that I, the said Richard Archibald
Brooman, my executors or administrators, by an instrument in writing under
any, 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
5 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
aleclare the nature of the said Invention, and in what manner the same is to
O be performed to be particularly described and ascertained in, and by the
following statement thereof, that is to say:
The chief object of the Invention is; to render cast-iron suitable for articles
of furniture free from all liability to oxidation, and to ornament it by the
application of the coloring and decorative processes used to ornament ceramic
5 wares.
In order to apply the ornamentation it is necessary the metal should
receive à preparation; that is, it must be covered by a vitrified varnish, upon
which the ornamentation or decoration is applied. I obtain this coating in
all colors by employing in a dry state, as hereafter stated, opaque enamels in a

page_text: proper state of fusibility for spreading over the metal, together with coloring
oxides used in vitrifiable colors. By this Invention imitations of marble,
precious stones, various woods, are among those obtained on cast-iron and
other metals.
The method of proceeding is as follows:-The pieces of metal, say, cast-iron,
are cleaned and washed, and placed in a furnace or muffle heated 'to a red
heat, as soon as the metal has attained the same temperature as the furnace
it is withdrawn, and the enamel is sifted on it. When the metal is evenly
covered with the enamel it is again inserted in the furnace where it is kept
until the enamel forms a beautiful glaze. Uncolored enamels produce, by
combining with the oxide of iron, which forms on the surface of the heated
metal à vitrification having the' appearance of black marble. When coól
the enamelled surface may be ornamented in colors with a brush as practiséd
.on glass and pottery. Imitations of marbles, woods, and stones of different
colors are also produced by a brush in any design according to the taste and
skill of the artist. Gilding and silvering are applied on the enamel as on glass
and porcelain, but in order to heighten the effects produced as before described,
I apply metallic and other lustres varied by mixtures of colors with the
metallic lustres or by the action of smoke on the lustres. After the colors
and lustres have been applied the enamelled metal is again placed in the
furnace. The lustres which are developed by the action of gas or smoke on
colors containing oxide of silver permit of a more extended application than
has hitherto been obtained on porcelain or pottery, and this is owing to being
'enabled to remove and examine the metal, while red, without its being liable
to a draught of air breaking it as would be the case with porcelain. To
facilitate the operation of smoking the lustres, as the pieces issue from the
muffle they are placed in a closed vessel, where, by means of a tap, wood, smoko,
gas, or steam is introduced. This tap is placed in communication with a smokė
or gas receiver by means of a caoutchouc tube so that when the action is only
required on one part an attendant directs the gas to that part. The furnaces
or muffles are made in proportion to the size of the articles to be manufac-
tured with a door at each end. To avoid as much as possible loss of heat
these doors are made of fire-brick held in a metal frame. In order that the
doors may open and close with facility they are fitted and work in slides
placed at the sides of the entrance, they are each suspended at the end of a
lever at the other extremity of which there is a counterweight.
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 improvements
in preparing and ornamenting cast-iron, and other metals in order to fit them

page_text: for articles of furniture, and decoration, and other similar uses in manner
herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have
hereunto set my hand and seal, this Twelfth day of August, One
thousand eight hundred and sixty-two.
