HENRY JEFFERIES Gas Manager Stourport County of Worcester I Henry Jefferies
Gas Manager Stourport County of Worcester do hereby declare the nature of this
invention for AN IMPROVED HYDRAULIC APPARATUS OR VALVE TO BE USED IN THE
MANUFACTURE OF COAL & OTHER GASES OR FOR OTHER SIMILAR PURPOSES to be as
follows:-
The object of my invention is to produce a Valve simple in its construction and
reliable in its action. The ordinary method of conveying Gas from the Retorts to the
Hydraulic Main is to force it through a body of water thus causing waste of Gas and
greater consumption of Coal.
By my invention I construct a valve in the following manner near the Retorts and
in direct communication with the ascension pipes. The Gas "having flowed up
the aforesaid ascension pipes" is passed freely on into a cylinder, fitted internally at
bottom with another cylinder smaller in diameter than the inside of the outer cylinder
and between these two cylinders a reservoir is formed for the purpose hereinafter
described. The bottom of the inside cylinder projects below the bottom of the outer

HENRY JEFFERIES Gas Works Manager Stourport, County of Worcester I Henry
Jefferies do hereby declare the nature of my invention for AN IMPROVED HYDRAULIC
APPARATUS OR VALVE TO BE USED IN THE MANUFACTURE OF COAL AND OTHER GASES
OR FOR OTHER SIMILAR PURPOSES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The object of my invention is to produce a valve simple in its construction and
reliable in its action. The ordinary method of conveying gas from the Retorts to
the Hydraulic Main is to force it through a body of water thus causing a waste of
Gas and a greater consumption of coal by my invention 1 construct a valve in the
following manner. Near the Retorts and in direct communication with the ascension
pipes, "the Gas having flowed up the aforesaid ascension pipes" is passed freely on
into a cylinder fitted internally at the bottom with another cylinder smaller in
diameter than the inside of the outer cylinder and between these two cylinders a
reservoir is formed for the purpose hereinafter described.
The bottom of the inside cylinder projects below the bottom of the outer cylinder
and acts direct with the exhaust or Gasholder. A hollow cup or plunger is fitted to
fall between the inner and outer cylinder thus forming a seal to prevent escape of
gas from the Gasholder.
At the top of the before described is also formed a cylinder of less diameter and as
before described forming a reservoir fitted with a cup or plunger. This top plunger
is connected with the bottom plunger by a Rod or chain and is raised or lowered with
wheel or lever by manuel or mechanical power. The top plunger as before described
is to prevent the escape of Gas when the bottom plunger is raised for the gas to pass
into the Gasholder and thus remove all pressure from the Retorts and preventing
corrosion of the same and a maximum yield of Gas is created from the coal
carbonized.
I will now describe with reference to the accompanying drawings the manner in
which my invention is to be performed. Fig. I represents a transverse sectional view
of the valve or apparatus open. A. Hydraulic main. B. bottom chamber or Cylinder.

of gas when the valve is open. E bottom cup or plunger. F top cup or plunger.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is with respect to the apparatus or valve
First. At one operation a Free passage is opened for the gas to pass from the
Retorts towards the Gasholder.
Secondly. Simplicity and freeness of action of each part of the apparatus
"packing & stuffing boxes being dispensed with."
Thirdly. When the apparatus is closed the bottom chamber acts as a dip pipe and
therefore the dip pipe in Hydraulic main is not required.
Fourthly. Prevention of corrosion or carbonizing of the Retort and also prevents
the Retorts from cracking or breaking and also prevents the stopping up of the
ascension pipes.
