IMPROVEMENTS IN THE TREATMENT OF SLAG OR SCORIA AND OF IRON
Year: 1875

page_text: LETTERS PATENT to John James Bodmer, of 23, the Grove, Hammer-
smith, and Louis Rudolph Bodmer, of 2, Lansdowne Road, Notting
Hill, both in the County of Middlesex, for the Invention of
PROVISIONAL SPECIFICATION left by the said John James Bodmer
and Louis Rudolph Bodmer at the Office of the Commissioners of
Patents, with their Petition, on the 23rd March 1875.
We, JOHN JAMES BODMER, of 23, the Grove, Hammersmith, and
LOUIS RUDOLPH BODMER, of 2, Lansdowne Road, Notting Hill, both in
the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE TREATMENT OF SLAG OR SCORIA AND OF
IRON," to be as follows:-
Our Invention relates to certain processes applicable to the treatment.
of slag or scoria from blast furnaces and other smelting furnaces, for the
purpose of subdividing or granulating the same, which processes are also

page_text: applicable to iron whilst in a liquid condition, for the purpose of partly
purifying or fining and for subdividing or granulating it.
In carrying out the said improvements in the treatment of slag or
scoria we use one or more jets of water applied in any convenient shape
or form. The water under the requisite pressure is projected against t
inflow stream or streams of slag or scoria as it issues from the furnace or
spout in its more or less fluid or viscous condition and in any desired
direction. The flow or stream of the slag or scoria is thereby divided
and dispersed, and at the same time cooled and disintegrated, and may
at once be made to deposit itself in a truck or waggon or other 1
convenient receptacle. Or it is made to drop upon a screen or screens,
fixed or moveable.
When it is desired to obtain the subdivided or granulated slag in a
more or less dry condition, the water after it has been in contact with
the slag is intercepted by a plate or plates or by other means, and guided 1
away and out of contact with the slag.
In carrying out the said improvements in the treatment of iron, we
also direct a jet or jets of water against the stream as it flows from a
furnace, apparatus, or receiver, in a more or less liquid condition.
The water projected against the metal in one or several directions with
the necessary pressure or force, disperses the flow of the metal, dividing
the same into granules which are made to drop into receivers of any
desired description, containing water for the further cooling the iron; or
in place of water jets we use steam jets in a similar way, and for the
same purpose again allowing the granules to drop into receivers con-
taining water. Or the flow of metal is first guided over a more or less
expanded surface or surfaces of any convenient shape, steam being made
to play on it through jets of any required form and number, whereby a
purifying influence is obtained, and jets of water then applied before the
metal is allowed finally to drop into a receiver or receivers containing
water.
Both the water applied by jets and that contained in the receivers or
either, may be made to contain chemical admixtures, such as common
salt or others. If required the water in the receiver or receivers is
agitated.
The aim and purpose of our Invention is in reference to slag or scoria,
the removal of the same from the furnaces in an inexpensive way and in

page_text: a convenient form; also the production of that material in the form of
sand or granules without the direct application of machinery, and in a
more or less dry condition, for purposes named, amongst others in
Specifications of the Patents of Bodmer, No. 1041, 1866; No. 615, 1868;
No. 1970, 1866; No. 3557, 1872. And in reference to iron, a partial
fining and an effective subdivision or granulation by equally inexpensive
means, the conditions of granulation being of advantage in the further
treatment of the metal, chiefly so in subsequent puddling or steel melting
processes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John James Bodmer and Louis Rudolph Bodmer
in the Great Seal Patent Office on the 23rd September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JoHN JAMES
BODMER, of 23, the Grove, Hammersmith, and LOUIS RUDOLPH Bodmer,
of 2, Lansdowne Road, Notting Hill, both in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of March, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said John James Bodmer and Louis Rudolph
Bodmer, Her special licence that we, the said John James Bodmer and
Louis Rudolph Bodmer, our executors, administrators, and assigns, or
such others as we, the said John James Bodmer and Louis Rudolph
Bodmer, our 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,
excrcise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN THE TREATMENT OF SLAG OR SCORIA AND OF IRON," upon the
condition (amongst others) that we, the said John James Bodmer and
Louis Rudolph Bodmer, our executors or administrators, by an instru-
ment in writing under our, or one of our, 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 was to be performed, and

page_text: 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 John James Bodmer, on behalf of
myself and the said Louis Rudolph Bodmer, 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, that is to say:
Our Invention relates to certain processes applicable to the treatment
of slag or scoria from blast furnaces and other smelting furnaces, for the
purpose of subdividing or granulating the same, which processes are also
applicable to iron whilst in a liquid condition, for the purpose of partly
purifying or fining, and for subdividing or granulating it.
In carrying out the said improvements in the treatment of slag or
scoria, we use one or more jets of water applied in any convenient shape 1
or form. The water under the requisite pressure whether from a head
of water or from a pump injector or ejector is projected against the flow
stream or streams of slag or scoria as it issues from the furnace or spout
in its more or less fluid or viscous condition and in any desired, direction.
The flow or stream of the slag or scoria is thereby divided, dispersed, and
disintegrated, and at the same time cooled and may be made to at once
deposit itself in a truck or other convenient receptacle; or it may be
made to fall upon a screen or screens, fixed or movable.
When it is desired to obtain the subdivided or granulated slag in a
more or less dry condition, the water after it has been in contact with 2
the slag is interrupted by a plate or plates screened, or by other means,
and guided away out of contact with the slag.
In carrying out the said improvements in the treatment of iron, we
also direct a jet or jets of water against the stream as it flows from a
furnace, finery, receiver, or other apparatus, in a more or less liquid 3
condition.
The water projected against the metal in one or in several directions
with the necessary pressure or force, disperses the flow of the metal,'
dividing the same into granules which are made to drop into receivers of
any desired description, containing water for the further cooling of the 3
iron; or in place of water jets we use steam jets in a similar way or
steam and water simultaneously, and for the same purpose again allowing

page_text: the granules to drop into receivers containing water. Or the flow
of metal is first passed over a more or less expanded surface or
surfaces of any convenient shape, steam jets being made to play upon
it whereby a purifying influence is obtained, and jets of water are
then applied before the metal is allowed to finally drop into a receiver
containing water.
Both the water applied by the jets and that contained in the receivers,
or either, may contain chemical admixtures such as common salt or
others; or the granules may be carried away by any convenient means
without being allowed to drop into a liquid.
The aim and purpose of our Invention is in reference to slag or scoria,
the removal of the same from the furnaces in an inexpensive way and
convenient form, and also the conversion of slag into sand or granules
without direct application of machinery, and in a more or less dry
condition for the purposes named, amongst others in the Specifications of
the Patents of Bodmer, No. 1041, 1866; No. 1970, 1866; No. 615, 1868;
No. 3557, 1872; No. 590, 1873; and with reference to iron a partial
fining and an effective subdivision or granulation by equally inexpensive
means, the condition of granulation being of advantage in the further
treatment of the metal chiefly so in subsequent puddling or steel melting
