IMPROVEMENTS IN THE MANUFACTURE OF ANVILS
Year: 1853

page_text: LETTERS PATENT to Richard Archibald Brooman, of the firm of
Robertson, Brooman, and Company, of 166, Fleet Street, in the
City of London, Patent Agent, for the Invention of "IMPROVE-
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 14th July 1858.
I, RICHARD ARCHIBALD BROOMAN, of the firm of Robertson,
Brooman, and Company, of 166, Fleet Street, in the City of London,
Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF ANVILS" to be as follows:-
This Invention consists of certain improvements in the manufacture
of anvils, whereby they are composed of a cast iron body combined
with a steel face and horn or beak, or with a face of steel and a horn
of malleable or wrought iron. Anvils thus constructed are very
superior to those of the cominon make, as they will wear much longer,
and will not soften or break down under heavy hammering on large
masses of heated metal. As a process of construction, the following is
a good method:-In the first place; a piece of steel is formed of a
proper shape to make the face; then, if the horn or beak is to be of
malleable iron, it is properly forged and welded to the steel face, or to
a point of steel projecting therefrom. The steel thus prepared is laid

upon a plate of iron having an opening nearly as large as the prepared
steel, and is secured in this position by set screws. The mould of the
anvil is then formed upon this plate, a flask of the usual construction
being employed, of which the iron plate forms the bottom.
mould is of the usual shape, except that it has a core by which a
hole is left in the casting, either extending up into the body or in any
suitable direction through the casting, and the purpose of which will
be shown hereafter. When the mould is ready to receive the melted
iron it is to be set upon a furnace, and to remain there until the steel
has attained a welding heat, the fire coming in contact with the steel
through the opening in the iron plate, and some proper flux being
applied upon the steel. The flask is now to be removed to a bed of
sand, and the melted iron poured in to form the body of the anvil,
thus welding to the cast iron the steel face and the horn.
After the casting has been properly cleaned, chipped, and ground,
the process of tempering the face must be gone through. For this
to be successfully performed the cavity before mentioned is required.
The anvil is re-heated, and the proper temper is attained by the applica-
tion of water or other suitable fluid both to the surface and to the
cavity in the casting. This insures an equal shrinkage, without which
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Archibald Brooman in the Great Seal
Patent Office, on the 14th January 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
RICHARD ARCHIBALD BROOMAN, of the firm of Robertson, Brooman,
& Co., 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 Fourteenth day of July, in the year of
our Lord One thousand eight hundred and fifty-three, in the seventeenth
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, admi-

page_text: nistrators, and assigns, or such others as J, 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 there-
after 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 "IMPROVEMENTS IN THE MANUFACTURE OF ANVILS," communica-
tion from a foreigner residing abroad, upon the condition (amongst
others) that I, the said Richard Archibald Brooman, by an instru-
ment in writing under my hand and seal, should particularly describe
aud 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 ascer-
tained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, that is to say:
This Invention consists of certain improvements in the manufacture
of anvils, whereby they are composed of a cast iron body combined
with a steel face and horn or beak, or with a face of steel and a horn
of malleable or wrought iron. Anvils thus constructed are very
superior to those of the common make, as they will wear much
longer, and will not soften or break down under heavy hammering on
large masses of heated metal.
As a process of construction, the following is a good method:-In
the first place, a piece of steel a, is formed of a proper shape to
make the face; then, if the horn or beak is to be of malleable iron,
it is properly forged and welded to the steel face, or to a point of steel
projecting therefrom, as shewn at b. The steel thus prepared is laid
upon a plate of iron c, having an opening nearly as large as the pre-
pared steel, as represented in dotted lines in Figure 3, and is secured
in this position by set screws d, d. The mould of the anvil is then
formed upon this plate; a flask d', of the usual construction being
employed, of which the iron plate c, forms the bottom. The mould

page_text: is of the usual shape, except that it has a core by which a hole is left
in the casting, either extending up into the body, as represented at E,
or in any suitable direction through the casting, and the purpose of
which will be shown herein-after. When the mould is ready to receive
the melted iron it is to be set upon a furnace, and to remain there
until the steel has attained a welding heat, the fire coming in contact
with the steel through the opening in the iron plate c, and some proper
flux being applied upon the steel. The flask is now to be removed to a
bed of sand, and the melted iron poured in to form the body of the anvil,
thus welding to the cast iron the steel face and the horn. After
the casting has been properly cleaned, chipped, and ground, the process
of tempering the face must be gone through. For this to be success-
fully performed the cavity E, before mentioned is required. The anvil
is re-heated, and the proper temper is attained by the application of
water or other suitable fluid both to the surface and to the cavity E,
in the casting. This ensures an equal shrinkage, without which the
solidity of the metal could not be secured.
And having now described the nature of the said Invention, and in
what manner the same is to be performed, I declare that what I
claim is,-
First, the making of a cast iron anvil having a steel face and horn
or beak, or of a face of steel and a horn of malleable or wrought iron,
welded thereto, as hercin-before described, and represented in the
Drawings hereunto annexed; and,
Second, the tempering aperture in the body of the cast iron, sub-
stantially as herein-before described.
-In witness whereof, I, the said Richard Archibald Brooman, have
hereunto set my hand and seal, this Fourteenth day of January,
One thousand cimbi hundred and fifty-four
