This invention relates to a construction of hydraulic main and valves for
conducting gases and other products of distillation from coke ovens, gas retorts,
gas producers, and other apparatus for distilling carbonaceous matters in such a
manner as to allow of the free passage of the gas from the oven, retort or producer
without having to pass through a liquid seal, to avoid the clogging of the passages
by condensed tar pitch or other similar matter and to give ready access for cleansing
or repair, and to allow of by pass from any of the pipes connected to the main
without interfering with the others. For this purpose, we construct the hydraulic
main in the form of a trough with its upper part divided into three compartments
by a cover formed as an inverted trough having its two sides dipping into the
liquid of the main, so that there is a middle compartment closed at the top forming
the longitudinal passage for gas and two side compartments provided with covers
that can be removed so as to give access for cleansing. Each of the pipes leading
gas into the main passes from below it through the bottom into the middle com-
partment of the main and extends upwards within the main some distance above
the level of the liquid therein, the main being kept charged to a certain height with
the liquid products of distillation and, if necessary, additional water. Immediately.
above the mouth of the pipe there is an opening of larger diameter through the
cover of the main, and this opening is provided with a hydraulic valve of the
following description.
Around the opening through the cover there is an annular trough containing
water or liquid and through the opening a short tube somewhat larger than the

short tube there is a flange from which a shorter outer tube of larger diameter

on and the valve is raised, the lip of the outer tube still remaining immersed in the
liquid in the annular trough, thus sealing the passage to the outer air, the gas pipe
leading from below into the hydraulic main is then open to the gas space thereof
and delivers the gases into the middle compartment. When it is desired to cut off
this pipe from the hydraulic main, the hydraulic valve is lowered so that the inner
tube thereof dips into the liquid in the hydraulic main around the gas pipe and so
seals the passage from it to the gas space of the main. The cover of the valve can
then be removed, giving free passage from the gas pipe to the outer air (a small
chimney being put on to the top of the valve if necessary) and also giving ready
facilities for cleaning out the gas pipe. The gases may be drawn off entirely
through the gas compartment of the hydraulic main, or they may if preferred be
drawn off partly through the hydraulic main and partly through a pipe in connec-
tion therewith. If a further by pass be desired it can be supplied by the addition
of another main with necessary embranchments.
Instead of arranging the connection between the hydraulic main and the oven
retort or other appliance in the manner above described, that is to say, with the
gas or ascension passing direct from the oven etc through the bottom of the
hydraulic main, the latter may be used in conjunction with the usual arrangement
of ascension pipe, horizontal pipe and dip-pipe (sometimes called the H pipe) by
having a vertical branch from the horizontal pipe (preferably an upward continua-
tion of the dip-pipe) and causing this upright pipe to pass through the bottom of a
hydraulic main of the construction already described.

Iroducts or Distilation from Coke Ovens,
Gas Retorts, Gas Producers, or other Apparatus for the
Distillation of Carbonaceous Substances.
We, HENRY SIMON of No 20 Mount Street Manchester in the County of
Lancaster, Civil Engineer, and WILLIAM CHARLTON of Guisborough in the County
of York, Mining Engineer do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:—
This invention relates to a construction of hydraulic main and valves for
conducting gases and other products of distillation from coke ovens, gas retorts,
gas producers and other apparatus for distilling carbonaceous matters in such a
manner as to allow of the free passage of the gas from the oven, retort or producer
without having to pass through a liquid seal, to avoid the clogging of the passages
by condensed tar, pitch or other similar matter and to give ready access for cleansing
or repair, and to allow of by pass from any of the pipes connected to the main
without interfering with the others. For this purpose, we construct the hydraulic
main in the form of a trough with its upper part divided into three compartments
by a cover formed as an inverted trough having its two sides dipping into the
liquid of the main, so that there is a middle compartment closed at the top forming
the longitudinal passage for gas and two side compartments provided with covers
that can be removed so as to give access for cleansing. Each of the pipes leading
gas into the main passes from below it through the bottom into the middle com-
partment of the main and extends upwards within the main some distance above
the level of the liquid therein, the main being kept charged to a certain height with
the liquid products of distillation and, if necessary, additional water. Immediately
above the mouth of the pipe there is an opening of larger diameter through the
cover of the main, and this opening is provided with a hydraulic valve of the
following description.
Around the opening through the cover there is an annular trough containing
water or liquid and through the opening a short tube somewhat larger than the gas
pipe is free to be moved up or down over the latter. At the upper end of this short
tube there is a flange from which a shorter outer tube of larger diameter projects
downwards into the liquid in the trough, thus forming a seal.
The tubular valve is provided with a removeable cover.
When this cover is put
on and the valve is raised, the lip of the outer tube still remaining immersed in the
liquid. in the annular trougb, thus sealing the passage to the outer air, the gas pipe
leading from below into the hydraulic main is then open to the gas space thereof
and delivers the gases into the middle compartment. When it is desired to cut off.
this pipe from the hydraulic main the hydraulic valve is lowered so that the inner
tube thereof dips into the liquid in the hydraulic main around the gas pipe and so
seals the passage from it to the gas space of the main. The cover of the valve can
then be removed, giving free passage from the gas pipe to the outer air (a small

page_text: chimney being put on to the top of the valve if necessary) and also giving ready
facilities for cleaning out the gas pipe. The gases may be drawn off entirely
through the gas compartment of the hydraulic main, or they may, if preferred, be
drawn off partly through the hydraulic main and partly through a pipe in connec-
tion therewith. If a further by-pass be desired, it can be supplied by the addition
of another main with necessary embranchments.
Instead of arranging the connection between the hydraulic main and the oven,
retort or other appliance in the manner above described, that is to say, with the
gases or ascension passing direct from the oven & through the bottom of the
hydraulic main, the latter may be used in conjunction with the usual arrangement
of ascension pipe, horizontal pipe and dip pipe (sometimes called the H pipe) by
having a vertical branch from the horizontal pipe (preferably an upward con-
tinuation of the dip pipe) and causing this upright pipe to pass through the bottom
of a
a hydraulic main of the construction already described.
Figs. 1 to 4 of the accompanying drawings shew the arrangement of our above
described invention which we prefer to employ. Fig. 1 shews a part side view,
partly in section, Fig. 2 shews a cross section, with the tubular valve in the raised
position; Fig. 3 shews a cross section with the tubular valve in the lowered
position; Fig. 4 shews an arrangement of travelling crane for raising and lowering
the tubular valve.
In this arrangement, the gas from the retort or coke oven passes through the
ascension pipe A and horizontal pipe B into the double branched pipe CC, of which
the branch C passes down into the hydraulic main D where its end is sealed by
dipping into the liquid, while the branch C¹ passes up through the bottom of tho
upper hydraulic main D¹ and through the liquid contained therein, opening into
the space E, into which consequently the main body of the gases are delivered
without having to pass through a liquid seal. The upper hydraulic main D¹ is
divided by two longitudinal partitions or flanges F F pendant from the cover and
dipping into the liquid, into three.compartments, namely a central one E into which
the gases issue as stated, and two side compartments E¹, which are provided with
covers for gaining access to the interior for cleansing purposes. In the top of the
main immediately above the pipe C¹ is a circular hole, above which is fixed a
tube F passing up through a longitudinal water trough G formed along the top of
the cover. Through the tube F1 passes the tubular valve H, the internal diameter
of which is such that when lowered it will pass freely over the pipe Cl as shewn
at Fig. 3, and, in dipping into the liquid surrounding it, cuts off the communication
between the pipe and the hydraulic main 11, and as the lower branch C is sealed
by the liquid in the hydraulic main D, the horizontal pipe B ascension pipe A and
retort or oven are thus cut off from the hydraulic mains and can be opened for
discharging, charging cleansing or repairs.
The top of the tubular valve H may be closed, but by preference it is provided
with a removeable cover H', which can be removed when the valve is lowered, as
at Fig. 3; so as to give free passage from the pipes A and B. to the outer air, and
to enable the pipe CC to be cleared. On the upper end of the valve H is fixed or
formed a second tube or bell H which dips into the water in the trough G and
thus prevents the escape of any gas from the compartment E between the valve H
and tube F
The lower hydraulic main D is divided by a partition into two compartments;
one I into which the pipe C dips and one I which is provided with removeable
covers for cleansing purposes; into the compartment I pass any liquid products
that may be condensed from the gas as it passes up the pipe C into the hydraulic
main D. It also serves as a by-pass to the hydraulic main D', in cases where any
portion of this requires to be cleaned out or repaired, for which purpose the com-
partments E and I are connected together at intervals by vertical pipes J Fig. 1,
which pass up through the liquid in the compartment E, and which may also be
used for equalising the pressure in the hydraulic mains by regulating their apertures.
Both bydraulic mains are also counected at their ends by pipes K to pipes L for

page_text: leading off the gases, and the overflow pipe M of the upper main is also connected
to the overflow pipe N of the lower main.
The valves H are supported in their raised position by means of two or more
removeable props O Fig. 4 placed under their upper flange, and they are raised
and lowered by means of the travelling winch P.
As before stated, the above described construction of hydraulic main with
tubular valve may also be arranged directly over the ascension pipe of the retort,
producer or coke oven; the arrangement would then be same as at Fig. 3, the
pipe C¹ then representing the ascension pipe directly connected to the retort,
producer or coke oven.
Having now particularly described and ascertained the nature of our said-
invention and in what manner the same is to be performed, we declare that what
we claim is
1. In combination with the pipe that delivers the gases from a retort, gas
producer or coke oven into a hydraulic main, the use of a tubular valve so arranged
that when in the lowered position it encloses the open end of the gas supply pipe
and dips into the liquid in the main so as to cut off the communication of the
retort, producer or coke oven with the hydraulic main, while when the valve is
raised, the said communication is freely established, substantially as herein
described.
2. In a tubular valve such as is referred to in the preceding claim, providing the
upper end of the valve with a removeable cover, so that when in the lowered
position a communication can be established through it between the gas pipe and
the outer air for cleansing or other purposes, substantially as herein described.
3. In combination with a tubular valve such as is referred to in the preceding
claims, the use of a water trough having a vertical tubular passage through which
the valve works, the valve being provided with an outer cylinder or bell that dips
into the water in the trough so as to form a liquid seal preventing the escape of
gas from the hydraulic main, substantially as herein described.
4. The combination of a hydraulic main divided into compartments by pendant
partitions dipping into the liquid, with a gas ascension pipe rising through the
bottom of the main to a height above the liquid in one of the said compartments,
substantially as herein described.
5. Constructing hydraulic mains with two pendant longitudinal partitions or
flanges dipping into the liquid thus forming a central compartment into which the
gas issues, and two side compartments accessible through covers, substantially as
herein described.
6. The combination of a double branched gas ascension pipe with an upper and a
lower hydraulic main, in such manner that the one branch pipe passes up through
the bottom of the upper main, which is provided with a tubular valve such as is
referred to in the first claim while the other branch passes down through the cover
of the lower main and dips into the liquid therein, substantially as herein
described.
7. In the combination of two hydraulic mains with a double branched gas pipe
referred to in the preceding. claim, arranging the lower hydraulic main as a
by-pass to the upper one by providing at intervals vertical connecting pipes
between the two substantially as herein described.
