HENRY GREENE and THOMAS ARTHUR GREENE [both of 155 Cannon Street in
the City of London] A NEW OR IMPROVED GOVERNOR OR REGULATOR FOR
REGULATING THE SUPPLY OF GAS OR OTHER AERIFORM FLUIDS
This invention relates to a new or improved Governor or Regulator for regulating
the supply of Gas or other aeriform fluids
And consists of an apparatus, the construction of which, is based upon, and is an
application of, the laws of Hydrostatics to the regulation of Gas supply
The letters hereinafter mentioned correspond with the letters in the annexed
drawing
For the above purpose we construct a vessel of any suitable size, shape or
material as A open at the top, and having an open tube B inserted in the bottom
(gas and water tight) which tube is carried up into A to a suitable height
"
We also construct a hollow water-tight vessel or float C of such shape as will
leave a hollow space D of sufficient height so as to cover the tube B-the said
space D being gas and watertight except the bottom which is open and com-
municates with A
Under the vessel A we construct a gas box F to admit of the insertion of the
outlet pipe G-into the lower part of this box we insert and fix the seating of a
conical valve H.
Near the top of the vessel A we place a stretcher L pierced with a hole ✪ of
sufficient size to admit of the guide rod M.

page_text: We now attach the valve N to the guide-rod, passing through the float at
points ZZ (which points are made gas tight), and through the stretcher L so as to
move freely at O
The guide rod is then turned at a suitable angle the horizontal part thereof
being loosely held in the groove P which is attached to the upper side of the
stretcher L which together steady the float C.
Under the Gas box F we construct another Gas box I of sufficient dimensions to
allow free play to the valve N and also to admit the inlet pipe K
When the inlet pipe and outlet pipe above described are connected with the
gas pipes; it is put into action by first closing the ordinary service tap leading to
the inlet pipe K then opening one or more of the taps or other outlets connected
with the outlet pipe G and pouring in a sufficient quantity of a suitable liquid
preferably glycerine, to just raise the float C, the gas is then turned on full from
the service tap leading to K, and a further supply of the liquid is carefully and
gradually poured into A until the pressure of the gas at the burning point is
reduced to the required degree.
The Governor is now in action and any increase in the initial pressure of the Gas,
will exert a corresponding influence or pressure upon the surface of the liquid
contained in D and as the liquid contained in-A is open to the pressure of the
atmosphere, a portion of the liquid in D will be displaced or driven out, causing
the level of the liquid in A to rise and consequently proportionally raising the
float C, and still further closing the valve N the float at the same time receiving
a further acceleration in rising, by becoming more hollow at D in proportion to the
quantity of liquid displaced.
--
When the initial pressure of the gas decreases, the displaced liquid returns to D
and the former action is reversed.
By these means, however varying the initial pressure of the gas supply the
required degree to which it has been adjusted is constantly maintained As a
protection to the Governor a cover Q is put on but must be loose enough to allow
the access of the atmosphere.

the said Henry Greene and Thomas Arthur Greene in the Great Seal Patent
Office on the 26th April 1883.
HENRY GREENE and THOMAS ARTHUR GREENE both of 155 Cannon Street in
the City of London A NEW OR IMPROVED GOVERNOR OR REGULATOR FOR
REGULATING THE SUPPLY OF GAS OR OTHER AERIFORM FLUIDS
Our invention relates to a new or improved Governor or Regulator for regulating
the supply of gas or other aeriform fluids
Our invention relates to new or improved apparatus for the regulation of the
supply of gas or other aeriform fluids the construction of which is based upon an
application in the manner hereinafter described of Hydrostatic laws to the supply
of gas. Our apparatus by its automatic action governs a valve by means of the
pressure of gas or other aeriform fluids acting upon the surface of a liquid
contained in the apparatus and thereby acting upon a float connected by an
eccentric guide with the said valve
We accomplish this object in the manner hereinafter set forth and that our
description may be the better understood we shall refer to the annexed drawing
in which the letters correspond with these herein used. The drawings shew
sectional elevations of two modifications of our improved Governor each being
constructed according to our invention
One modification of our improved apparatus is shewn in figure 1 of the
annexed drawings which is intended to represont a Governor to control 50 Gas
lights consuming about 5 cubic feet per hour and the said drawing is about half
the size of such Governor which is here shewn of a cylindrical shape but it is not
necessary for the purposes of our invention that such form should be adhered to
We construct a vessel of a suitable shape size and material as A open at the top
and having an open tube B inserted in the bottom (gas and water tight) which
tube is carried up into A to a suitable height. We also construct a hollow gas
and water tight vessel or float C of such shape as will leave a hollow space D of
sufficient height to cover the tube B the said space D being gas and water tight
except the bottom which is open and communicates with A
The superficial area of the said space D being in proportion to the superficial
area of the space comprised between the exterior side of the float C and the
interior side of the vessel A about as 38 is to 54 but we do not confine ourselves
to this proportion when the proportions of the apparatus are varied
Under the Vessel A we construct a gas box F to admit of the insertion of the
outlet pipe G into the lower part of this box we insert and fix the seating of a
conical valve H Near the top of the vessel A we place a stretcher L pierced
with a hole O of sufficient size to admit of the guide M M M we now attach the
valve N to the guide passing through the float at points Z Z (which points are
made gas and water tight) and through the stretcher L so as to move freely at 0-
the guide is then turned at a suitable angle the horizontal or turned part thereof
being loosely held in the groove P which is attached to the upper side of the
stretcher L which together thus steadies the float C and prevents pulsation. Under
the gas box F we construct another gas box I of sufficient dimensions to allow free
play to the valve N and also to admit the inlet pipe K
When the inlet pipe and the outlet pipe above described are connected with the
gas pipes the governor is put into action by first closing the ordinary service tap
leading to the inlet pipe K then opening one or more of the taps or other outlets
connected with the outlet pipe G and pouring into the vessel A a sufficient

page_text: quantity of a suitable liquid (preferably glycerine) to just raise the float C; the
gas is then turned on full from the service tap leading to K and the whole of the
burners governed are to be lighted and a further supply of the liquid is carefully
and gradually poured into A until the pressure of the gas at the burners is reduced
to the required degree.
The Governor is now in action and any increase in the initial pressure of the gas
will exert a corresponding influence or pressure upon the surface of the liquid
contained in D and as the liquid in A is only subject to the pressure of the
atmosphere a portion of the liquid in D will be displaced or driven out causing the
level of the liquid in A to rise and consequently proportionately raising the float C
and still further closing the valve N the float at the eame time receiving a further
acceleration in raising by becoming more hollow at D in proportion to the quantity
.of liquid displaced
When the initial pressure of the gas decreases the liquid returns to D and the
former Action is reversed the float C sinking and the valve N opening
The use of adjusting weights is rendered unnecessary the adjustment of the
valve being determined by the height of the liquid to which the governor is
charged
By these means however varying the initial pressure of the gas supply the
required degree of pressure to which it has been adjusted at the burning point is
constantly maintained
Another modification of our improved apparatus is shewn in figure II of the
annexed drawings which like figure I is intended to reprosent a Governor to
control 50 Gas lights consuming about 5 Cubic foet per hour
In this modification like parts are indicated by the same letters as in figure I and
it will be seen that the sides of the float C are continued below the bottom of such
float so as to form a curtain which forms a reservoir for the liquid for use in case
of the contents of the space D being suddenly exhausted by an abnormal rise in
-the-pressure of the gas in such space
As a protection to the governor a cover Q is put on but it must be loose enough
to allow the access of the atmosphere
Having now described and fully ascertained the nature of our said invention
and the manner of carrying the same into practice we would observe in conclusion
that we do not restrict or confine ourselves to the precise details we have described
or referred to as variations may be made therefrom without deviating from the
principles of this Invention but what we consider to be novel and original and
therefore claim as the invention secured to us by the hereinbefore in part recited
letters patent is
First The use in a governor or regulator for regulating the supply of gas or other
aeriform fluids of an eccentric guide attached to the Hoat and the valve
substantially as described
Second A governor or regulator for regulating the supply of gas or other
aeriform fluids substantially constructed as described and as respectively
illustrated in the annexed drawings or any mere modification of the same
In witness whereof the said Henry Greene and Thomas Arthur Greene have
hereunto set their hands and Seals this twenty fifth day of April in the
Year of our Lord One Thousand Eight Hundred and Eighty three.
