I, WILLIAM COULSON PARKINSON of Cottage Lane, City Road, in the County of
Middlesex, Gas Apparatus Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object the construction of Station gas governors in such
a manner that the cones shall not be affected by any variation of the inlet pressure.
The invention consists of a tank containing water in which a bell or gasholder
having a float or air chamber at its lower part rises and falls between suitable guides.
Beneath the tank there is a casting having an inlet and outlet, and a partition which
divides the interior space into an inlet and outlet chamber. This partition has two
valve seats formed in it, one on its upper side and one on its lower side. From the
bell or gasholder there are suspended by a rod two conical valves, commonly called
cones,'
"that rise and fall with the bell, and so close or open the gas ways between
the cones and their respective seats. The rod supporting the cones passes through a
small hole in the cover plate of the stand pipe of the tank. From the outlet of the
governor there is a pipe which passes through the bottom of the tank and rises above
the water level where it opens into the bell.
The action is exceedingly simple. Gas being admitted at the inlet, flows upwards
through the space between the upper cone and its seat, and downwards through the
space between the lower cone and its seat, and from thence to the outlet, the pressure
exerted upon the upper cone being counteracted by the same pressure operating upon
the lower one. The inlet gas therefore has little or no perceptible effect upon the
cones, but as the bell or gasholder has the outlet pressure conveyed to it through the
pipe before mentioned the outlet pressure becomes the actuating force and the bell
together with the cones rise and fall in conformity with it.
The bell instead of having a float or air chamber may be counterpoised by weights
as is often done in ordinary governors.

page_text: I, WILLIAM COULSON PARKINSON, of Cottage Lane, City Road, in the County of
Middlesex, Gas Apparatus Manufacturer 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 has for its object the construction of station gas governors in such a
manner that the cones shall not be affected by any variation of the inlet pressure and
shall maintain the constancy of the outlet pressure to whatever it may be adjusted.
In order that the invention may be easily understood a drawing exhibiting a
vertical sectional elevation of the governor is attached hereto.
The invention consists of a tank A containing water in which a bell or gasholder B
having a float or air chamber C at its lower part rises and falls between suitable
guides. Beneath the tank there is a casting having an inlet D and outlet E, and a
partition F, which divides the interior space into an inlet chamber G and an outlet
chamber H. This chamber G has two valve seats formed in it, one on its upper side
at I, and one on its lower side at J.
From the bell or gasholder there are suspended by a rod K two conical valves L
and M, commonly called "cones," that rise and fall with the bell, and so close or open
the gas ways between the cones and their respective seats. The rod supporting the
cones passes through a small hole in the cover plate N of the stand pipe O of the
tank. From the outlet of the governor there is a pipe P, which passes through
the bottom of the tank and rises above the water level where it opens into. the bell.
The action is exceedingly simple. Gas being admitted at the inlet, flows upwards
through the space between the upper cone and its seat, and downwards through the
space between the lower cone and its seat, and from thence to the outlet, the pressure
exerted upon the upper cone being counteracted by the same pressure operating upon
the lower one. The inlet gas therefore has little or no perceptible effect upon the
cones, but as the bell or gasholder has the outlet pressure conveyed to it through the
pipe before mentioned, the outlet pressure becomes the actuating force, and the bell
together with the cones rise and fall in conformity with it.
The bell instead of having a float or air chamber, may be counterpoised by weights,
as is often done in ordinary governors.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is,―
The combination of the double or equilibrium cones with the pipe P communicating
from the outlet gas to the inner side of the bell, the hole in the top of the standpipe
through which the cone rod passes being practically closed, as herein described and
-shown on the drawing.
