Improvements in the Manufacture of Coke, and in Apparatus and
Appliances connected therewith.
We, PERCIVAL MUSCHAMP, of Warren Grove, Barnsley, Mining Engineer, and
STEPHEN BURRIDGE, of 25, Change Alley, Sheffield, Merchant, both in the County
of York, do hereby declare the nature of our said invention to be as follows:-
Our invention relates to improvements in apparatus and appliances employed
for the cooling and preparation of coke after it leaves the oven in which it has
been burnt. We are aware that mechanical apparatus and appliances have been
employed for charging and discharging coke ovens, also that independent cooling
chambers or receptacles fixed or portable, have been employed for cooling or
slacking coke after it has been drawn or discharged from the oven or retort in
which it was burnt and we lay no claim to novelty, either for the employment of
mechanical means of charging or discharging coke ovens or in respect of the
employment of a secondary chamber either fixed or portable for cooling coke,
neither do we claim any novelty for the employment of steam in the said process.
The object of our invention is primarily to construct a cooling chamber which
can be employed in conjunction with one or more coking ovens or retorts which
shall utilize the heat given off by the fresh drawn charge of coke for generating
steam or gas, which steam or gas, is subsequently employed for cooling the charge
within the said cooling chamber.
We effect this by constructing our improved cooling chamber of a size internally
approximating to the interior dimensions of the coking ovens or retorts with
which it is to be used, so that when it is brought opposite to the door of such primary
oven or retort, the heated mass can be pushed or dragged into the cooling chamber
and when so charged the cooling chamber is closed by a door or doors provided for
the purpose. The side walls, end wall and roof, of our improved cooling chamber
we construct of metallic plates with rivetted or welded joints and made steam and
water tight. The space in the roof of the chamber being made large enough to form
both a water and steam space and the whole being made of sufficient strength to
be capable of withstanding a considerable amount of internal pressure. This
water jacketted and steam case of our improved cooling chamber being to all intents
and purposes a steam boiler and for which we provide similar mountings to those
usually employed in a steam boiler, as for example, water gauge glass or glasses and
petcocks, to indicate the level of the water, a feed valve for supply of water under
pressure, a safety valve for regulating the pressure within the case, a steam stop
valve for drawing off the steam, a blow-off cock or cocks for cleansing and
emptying the casing, also manholes and mudholes as may be required.
The cooling chamber here described may be constructed either fixed or portable,
by preference we should employ a portable form so that one or more such cooling
chambers could be moved about and used in conjunction with different coke ovens
or a range of ovens, so that when a charge has been received to undergo the
D

page_text: cooling and slacking process the cooling chamber can be moved bodily on a line
of rails to a convenient position for discharging its contents. In some cases we
construct the bottom of our improved cooling chamber with sliding or hopper
doors so that the contents may be discharged through the bottom, or in some cases
we employ a forcing ram or drag which may be operated mechanically for dis-
charging the contents.
The action of our improved apparatus will be as follows:-
When a charge of heated coke has been placed inside this water jacketted cooling
chamber and closed up, the heat which is given off by radiation, from the coke, will
be transmitted by conduction through the plates of the sides, end, and roof, of the
chamber to the water, and steam will be generated and stored. As soon as a
sufficient amount of steam has been raised for the purpose it is admitted by the
stop valve through pipes and nozzles to the interior of the cooling chamber, the
remaining heat in the coke being thereby slacked and cooled and when sufficiently
cooled the contents are discharged mechanically or otherwise and the apparatus
is moved to receive the contents of another coke oven or retort, when the operation
is repeated. In some cases the steam generated within the cooling chamber may be
used for other purposes besides cooling and slacking the charge, as for example, it
may be employed for actuating a forcing ram or other mechanical plants for
charging or discharging the contents of the cooling chamber or for propelling the
chamber on its carriage as may be required.

Appliances connected therewith.
We, PERCIVAL MUSCHAMP, of Warren Grove, Barnsley, Mining Engineer, and
STEPHEN BURRIDGE, of 25, Chauge Alley, Sheffield, Merchant, both in the County
of York, do hereby declare the nature of our said invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
Our invention relates to improvements in apparatus and appliances employed for
the cooling and preparation of coke after it leaves the oven in which it has been
burnt.
The object of our invention is primarily to construct a cooling chamber, which
can be employed in conjunction with one or more coking ovens or retorts, which
shall utilize the heat given off by the fresh drawn charge of coke for generating
steam which steam is subsequently employed for cooling the charge within the
said cooling chamber.
The nature of our invention will be better understood on reference to the accom-
panying sheet of drawings in which,
Fig. 1, is an end elevation of our improved cooling chamber.
Fig. 2, is a side elevation of the same.
Fig. 3, is a cross section of the same taken on the line A, B.
Fig. 4, is a longitudinal section of the same taken on the line C, D.
The same letters refer to similar parts throughout the several views.
We carry out our invention by constructing our improved cooling chamber, a,
of a size internally approximating to the interior dimensions of the coking ovens
or retorts with which it is to be used, so that when it is brought opposite to the

page_text: door of such primary oven or retort, the heated mass can be pushed or dragged into
the cooling chamber and when so charged the cooling chamber is closed by a
door or doors, b, provided for the purpose. The side walls, end wall and roof, c, c, c,
and c, c, c, of our improved cooling chamber we construct of metallic plates with
rivetted or welded joints and made steam and water tight. The space, d, in the
roof of the chamber being made large enough to form both a water and steam space
and the whole being made of sufficient strength to be capable of withstanding a
considerable amount of internal pressure. This water jacketted and steam case
of our improved cooling chamber being to all intents and purposes a steam boiler
and for which we provide similar mountings to those usually employed in a steam
boiler, as for example, water gauge glass or glasses, e, e, and pet-cocks, f, f, to indicate
the level of the water, feed valves, 9, 9, for supply of water under pressure, safety
valves, h, h, for regulating the pressure within the case, a steam stop valve, i, for
drawing off the steam, a blow-off cock or cocks, j, j, for cleansing and emptying
the casing, also manholes, k, k, and mudholes, 1, 1, as may be required.
The cooling chamber here described may be constructed either fixed or portable,
by preference we should employ a portable form carried on metallic framing, m, with
wheels, n, n, so that one or more such cooling chambers could be moved about and
used in conjunction with different coke ovens or a range of ovens, so that when a
charge has been received to undergo the cooling and slacking process the cooling
chamber can be moved bodily on a line of rails, o, o, to a convenient position for
discharging its contents. In some cases we construct the bottom of our improved
cooling chamber with sliding or hopper doors so that the contents may be discharged
through the bottom, or in some cases we employ a forcing ram or drag which may
be operated mechanically for discharging the contents.
The action of our improved apparatus will be as follows.
When the charge of heated coke has been placed inside this water jacketted
cooling chamber, a, and closed up, the heat which is given off by radiation from
the coke, will be transmitted, by conduction through the plates, c, c, c, forming the
inner walls of the chamber, to the water, and steam will be generated and stored.
As soon as a sufficient amount of steam has been raised for the purpose it is
admitted by the stop valve, i, through pipes ¹, and nozzles, 23, to the interior of the
cooling chamber, the remaining heat in the coke being thereby slacked and cooled
and when sufficiently cooled the contents are discharged mechanically or otherwise
and the apparatus is moved to receive the contents of another coke oven or retort,
when the operation is repeated. In some cases the steam generated within the
cooling chamber may be used for other purposes besides cooling and slacking the
charge, as for example, it may be employed for actuating a forcing ram or other
mechanical plants for charging or discharging the contents of the cooling chamber
or for propelling the chamber on its carriage as may be required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we wish it to be understood
that we are aware that mechanical apparatus and appliances have been employed
for charging and discharging coke ovens, also that independent cooling chambers
or receptacles fixed or portable, have been employed for cooling or slacking coke
after it has been drawn or discharged from the oven or retort in which it was
burnt and we lay no claim to novelty, either for the employment of mechanical
means of charging or discharging coke ovens or in respect of the employment of
a secondary chamber either fixed or portable for cooling coke, neither do we claim
any novelty for the employment of steam in cooling coke, but we declare that what
we claim is:-
In apparatus and appliances connected with the manufacture of coke the par-
ticular construction and combination of parts and appliances forming a cooling
chamber which can be employed in conjunction with one or more coking ovens or
retorts and by means of which the heat given off by the fresh drawn charge of
coke which is placed in the said cooling chamber to be cooled shall be utilized for

page_text: heating up the water contained in the casing thereof and for generating steam,
which steam may be employed for further cooling the charge of coke within the
Baid cooling chamber or for other purposes, in the manner and for the purposes
substantially as herein described and illustrated.
