GEORGE EDWARD VAUGHAN, of 67 Chancery Lane, in the County of Middlesex,
Patent Agent, "AN IMPROVED METHOD OF PRODUCING PRESSED COKE, AND
COKE-BRICKS, IN COKE FURNACES CONSTRUCTED TO WORK INTERMITTENTLY,"
A communication to me from abroad by Fritz Lürmann, of Osnabruck, in the
Empire of Germany,
•
In order to produce in the expelling chambers of coke furnaces, with intermittent
action, and inclined or arranged horizontally or vertically, moro solid coke from
coals, brown-coals, peat or from mixtures of the same and especially in order to
produce solid coke or coke-bricks out of a mixture of coking and non-coking
coals, the material to be coked is thoroughly pressed together in the expelling
chamber.
The required pressure against the materials to be coked is attained by any
suitable mechanical arrangements either during or after the process of filling the
expelling chamber.
The said pressure is caused to act on the contents of a coke furnace, of any known
and suitable construction and either inclined or arranged horizontally, from one or
both doors or from above.
In the case of a vertical coke furnace the pressure is caused to act on the contents
of the same, from above or from underneath, or in both directions.
The pressure is arranged to act on the whole or a portion of the contents of a
coke fornace.
The following is an example of a suitable method of applying this Invention to a

page_text: horizontal furnace, with two doors, of any ordinary and suitable construction, and in
this case the pressure is described as being exerted from one side and on parts of
the contents of the furnace. When the coke-furnace has been discharged, the door
is shut by any suitable apparatus, that can resist a strong pressure, a portion of the
material to be coked is then placed into the furnace from the top, and is pressed
together from the side by a coke pressing-machine or other suitable mechanical
arrangement. After the whole furnace is filled, and the material pressed together
by the means above referred to, the side, that is till then open, is shut under the
pressure used before, by a piston set out with bricks or by a door, so that the
material enters into the coking process, whilst under pressure.
As another example for the method of proceeding, the following is a description
of a method of applying this Invention to a vertical coke-furnace of ordinary
construction and in this case the pressure is described as being exerted from above
and on parts of the contents When the furnace has been discharged, the lower
door is shut by any suitable apparatus, that can resist a strong pressure, a part of
the materials to be coked is then filled in from above and a pressure exerted on the
same by any suitable mechanical arrangement. The apparatus for pressing is then
removed and another layer of the material to be coked is filled in, the pressing
apparatus is replaced and the material is again pressed together. This proceeding
is continued until the furnace is completely filled.
Any ordinary and suitable methods and apparatus for expelling and coking as
well as for discharging the coke are employed.

by the said George Edward Vaughan in the Great Seal Patent Office on the
15th December 1882.
GEORGE EDWARD VAUGHAN, of 67 Chancery Lane, in the County of Middlesex,
Patent Agent. "AN IMPROVED METHOD OF PRODUCING PRESSED COKE, AND
COKE BRICKS, IN COKE FURNACES CONSTRUCTED TO WORK INTERMITTENTLY,"
A communication to me from abroad by Fritz Lürmann of Osnabrück, in the
Empire of Germany,
In order to produce in the expelling chambers of coke furnaces, with intermittent
action, and inclined or arranged horizontally or vertically, more solid coke from
coals, brown coals, peat or from mixtures of the same, and especially in order to
produce solid coke or coke bricks out of a mixture of coking and non-coking
coals the materials to be coked are thoroughly pressed together in the expelling
chamber..
The required pressure against the materials to be coked is attained by any
suitable mechanical arrangements either during or after the process of filling the
expelling chamber,
The said pressure is caused to act on the contents of a coke furnace of any known
and suitable construction and either inclined or arranged horizontally from one or
both doors or from above.
In the case of a vertical coke furnace the pressure is caused to act on the contents
of the same, from above or from underneath or in both directions.
The pressure is arranged to act on the whole or a portion of the contents of a
coke furnace.
The following is an example of a suitable method of applying this Invention to a
borizontal furnace, with two doors, of any ordinary and suitable construction, and, in
this case, the pressure is described as being exerted from one side and on parts of
the contents of the furnace When the coke furnace has been discharged, the door
is shot by any suitable apparatus, that can resist a strong pressure, a portion of the
material to be coked is then placed into the furnace from the top, and is pressed
together from the side by a coke pressing machine or other suitable mechanical
arrangement. After the whole furnace has been filled and the material pressed
together, by the means above referred to, the side, that is till then open, is shut
under the pressure used before, by a piston set out with bricks, or by a door, so that
the material enters into the coking process, whilst under pressure.
As another example for the method of proceeding, the following is a description
of a method of applying this Invention to a vertical coke furnace of ordinary
construction and in this case the pressure is described as being exerted from above
and on parts of the contents. When the furnace has been discharged, the lower
door is shut by any suitable apparatus, that can resist a strong pressure, a part of
the materials to be coked is then filled in from above and a pressure exerted on the
same by any suitable mechanical arrangement. The apparatus for pressing is then
removed and another layer of the material to be coked is filled in, the pressing
apparatus is replaced and the material is again pressed together. This proceeding
is continued until the furnace is completely filled.
Any ordinary and suitable methods and apparatus for expelling and coking as
well as for discharging the coke are employed.
Having thus described and ascertained the nature of the said Invention and
in what manner the same is to be performed I would observe in conclusion that

page_text: what I consider novel and original and therefore claim as constituting the Invention
secured to me by the herein before in part recited Letters Patent, is -
The method of producing pressed coke or coke bricks, from coal, brown coal, peat
or mixtures of any of these materials in the expelling chambers, of coke furnaces,
arranged horizontally, or vertically or inclined, and with intermittent working, by
employing a mechanical pressure on the material during the time between the
filling and the discharging, substantially as hereinbefore set forth and described.
In witness whereof I the said George Edward Vaughan have hereunto set my
hand and seal this fifteenth day of December, in the year of our Lord One
thousand eight hundred and eighty two.
