Improvements in Valves for Use in connection with the Hydraulic
Mains of Gas Works and for analogous purposes.³
I, TOM SETTLE, of the Gasworks Knaresborough in the County of York,
Gasworks Manager, 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 consists of a combined valve for relieving the pressure on gas
or other retorts, allowing gas to travel, giving. greater facility for regulating the
seal and drawing off the tar and other liquors at pleasure from the hydraulic
mains or other receivers at gas or other works where apparatus of this kind is
required.
And in order that my invention may be thoroughly understood, 1 now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a vertical section of the apparatus.
Fig. 2, is a plan of the top of the apparatus.
The body of the valve B will be attached to the side of the hydraulic main A
and can be made to suit any section of hydraulic main. It will have a rib C cast
across to prevent the light liquors from over-flowing over rib D and thus the heavy
tar will be removed from the hydraulic main and always ensure a light seal.
The body B will be bored to receive the cylinder E which will have openings
cast in to suit the various opening in the body. This cylinder will be moved round
by means of wheel gearing of any suitable description.
When the valve is working the gas will travel over rib C in body, through the
openings F and G in cylinder, and pass on to the foul-main H. the tar will pass
under the rib C in body, and through the openings J and K in cylinder, over the
rib D, and down into the tar main L.
The seal may be increased by turning the cylinder round to the left when the
bottom part of opening K will be raised above the top of rib D and thus the
seal on dip pipes M in the hydraulic main A may be regulated as desired. An
aperture N will be made in the body so that the pressure of the gas is equal on
both sides of the valve.
If the cylinder E is turned round to the left until the rib O has cleared the
point P, then the valve will be closed and prevent communication between the
hydraulic main A. and the gas and tar mains H and L.
If the cylinder is turned still further round to the left until the rib O reaches
the bottom part of rib C then the tar and other liquors will be drawn from the
hydraulic main A. and pass under rib C in body, through the openings G and F in
cylinder, and through the opening R in body direct to the tar main L. By this
means the hydraulic main may be emptied and flushed.
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 :-
(1.) In valves, the combination of an apparatus in conjunction with hydraulic
mains of gasworks and analogous mains or pipes or other vessels having openings
or parts as heretofore described and communication with the interior of the vessel

page_text: and being capable of adjustment to regulate the seal in and to empty the hydraulic-
main, and to allow the gas to pass, and to shut off communication with any of
the discharge pipes herein described and illustrated in the accompanying
.drawing.
(2.) In valves, the combination of the apparatus of the class set forth, for the
regulation of seal, draw-off, and shut-off communication therewith without the use
of two valves, substantially as herein described and according to the accompanying
drawing.
