Improvements in Gas Regulators or Governors.
I WILLIAM THOMAS SUGG of Vincent. Works in the City of Westminster, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention consists in a novel arrangement of governor suitable for regulating
the supply of gas at two or more different pressures, and for various purposes..
It is well known that for cooking purposes a greater pressure is required than
for lighting purposes, and it is therefore necessary, in order to obtain thorough
regulation of the gas, to have two distinct governors, one for high pressure, and one,
very delicate in action, for low pressure, and a separate device for each.
Consumers, however, as a rule, do not care to go to the expense and inconvenience
of having two governors, and often two separate services, so as to secure the non-
interference of the cooking operations with the lighting arrangements, and therefore
generally use the gas to the cooking stove practically unregulated. They are usually
unaware of the fact that more gas is likely to be wasted, and food spoiled, by the
want of a proper control of the pressure of gas used in cooking, than would be
sufficient to pay for the lighting.
As it is not usual to have large service pipes fitted all over a building, more
especially a dwelling house, the effect of lighting up and extinguishing a gas cooking
stove entails usually a defective supply of gas for lighting purposes during the con-
tinuance of the cooking operations, and a too abundant supply when the cooking stove
is put out, and these variations cause waste and inconvenience. As before stated, it
is only possible to effectually control the waste and discomfort caused by these varying
conditions of supply and pressure, by having two separate governors and services,
and without these, the public have not been able to get either the amount of light
which the gas is capable of yielding, or that success in gas cooking operations which
they ought easily to obtain, if the gas supplies were properly regulated, so as not to
interfere with each other.
Now the object of this invention is to provide a double action governor, by which
the higher pressure of the gas supply to the kitchen may be controlled, and the
consumer be enabled to use the full pressure of the gas in the main, when, during the

page_text: day, it is at the lowest point, for cooking purposes, and two different pressures from
the same apparatus may be obtained at night, one suitable for cooking and the other
for lighting.
The action of the two combined governors is so extremely delicate, that it is
possible to employ low pressure burners, which develope the full illuminating power
that the gas is capable of giving, instead of those from which the gas issues at such a
high velocity that they develope only about half the light the gas is capable of
yielding, which type of burners have become almost universal because of the want of
a proper governor which will maintain the pressure at a sufficiently low point for
lighting, without at the same time diminishing the higher pressure required for
cooking.
In carrying out this invention, I prefer to use what are known as mercurial
governors, of which I may use two or more. For present purposes, I will however
refer to two governors only.
The body of the governor consists of a suitable casting having a central inlet
opening, and two lateral outlet openings, with which the service pipes are connected.
The casting is also formed with two annular concentric troughs for the mercury to
seal the domes, which carry conical valves in the usual manner.
The inner and smaller dome forms the high pressure regulator, and the larger and
outer dome, the low pressure regulator.
Above the lower dome, I provide a cover with a central lump, which forms a rest
for the valve of the upper dome. This cover, so to speak, divides the two governors.
Above this cover, is secured a second cover, in which is the valve seat for the upper
valve.
To prevent the escape of the mercury when the governor is placed on its side, I
secure, by rings or otherwise, to the upper edge of the inner wall of each trough, a
diaphragm of leather, which may be also attached at its centre to the crown of its
dome. This part of the invention is applicable to other mercurial governors.
The gas entering under the high pressure governor, passes by a lateral passage
partly to the high pressure service pipe, and partly by a suitable passage to the space
between the two covers, and thence by a suitable opening to the low pressure service
pipe. The whole governor will be closed in by a suitable cover, in which is a small
orifice for the entrance of the external air. A similar orifice is made for the lower
governor. Springs or weights will be provided above the domes to regulate the
pressure at which the governors work, in the usual manner.

Improvements in Gas Regulators or Governors.
WILLIAM THOMAS SUGG of Vincent Works, in the City of Westminster, 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 consists in a novel arrangement of governor suitable for regulating
the supply of gas at two or more different pressures, and for various purposes.
It is well known that for cooking purposes, a greater pressure is required than for
lighting purposes, and it is therefore necessary, in order to obtain thorough regulation
of the gas, to have two distinct governors, one for high pressure, and one (very
delicate in action) for low pressure, and a separate service for each.
Consumers, however, as a rule, do not care to go to the expense and inconvenience
of having two governors, and two separate services, so as to secure the non-interference
of the cooking operations with the lighting arrangements, and therefore generally use
the gas to the cooking stove practically unregulated. They are usually unaware of
the fact that more gas is likely to be wasted, and food spoiled, by the want of a proper
control of the pressure of gas used in cooking, than would be sufficient to pay for the
lighting.
As it is not usual to have large service pipes fitted all over a building more especially
a dwelling house, the effect of lighting up and extinguishing a gas cooking stove,
entails usually a defective supply of gas for lighting purposes during the continuance
of the cooking operations, and a too abundant supply when the cooking stove is done
with, and these variations cause waste and inconvenience. As before stated, it is only
possible to effectually control the waste and discomfort caused by these varying
conditions of supply and pressure, by having two separate governors and services, and
without these, the public have not been able to get either the amount of light required,
or that success iu gas cooking operations, which they ought easily to obtain, if the gas
supplies were properly regulated, so as not to interfere with each other.
Now the object of this invention is to provide a double action governor, by which
the higher pressure of the gas supply to the kitchen may be controlled, and the
consumer be enabled to use the full pressure of the gas in the main, when (during the
day) it is at the lowest point, for cooking purposes, and two different pressures from
the same apparatus at night, one suitable for cooking and the other for lighting.
The action of the two combined governors is so extremely delicate, that it is possible
to employ low pressure burners, which develope the full illuminating power that the
gas is capable of giving, instead of those from which the gas issues at such a high
velocity that they develope only about half the light the gas is capable of yielding,
which type of burners have become almost universal because of the want of a proper
governor which will maintain the pressure at a sufficiently low point for lighting,
without, at the same time, diminishing the higher pressure required for cooking.
In carrying out this invention, I prefer to use what are known as mercurial
governors, of which I may use two or more. For present purposes, I will however
refer to two governors only.

page_text: In the accompanying drawings,
Fig. 1 is a vertical section of governor arranged according to my invention,―and
Fig. 2 is a similar view, taken at right angles to Fig. 1.
The body of the governor consists of a suitable casting A, having a central
inlet opening B, and two lateral outlet openings CC, with which the service pipes
are connected. The casting is also formed with two annular concentric troughs D D¹,
for the mercury to seal the domes E E', which carry conical valves F F¹ in the
usual manner.
The inner and smaller dome E forms the high pressure regulator, and the larger
and outer dome E' the low pressure regulator.
Above the lower dome, I provide a cover G, with a central lump G¹, which forms
a rest for the valve F¹ of the upper dome E. This cover, so to speak, divides the
two governors. Above this cover, is secured a second cover H, in which is the
valve seat for the upper valve F¹.
To prevent the escape of the mercury when the governor is placed on its side, I
secure, by rings or otherwise, to the upper edge of the inner wall of each trough D D¹,
a diaphragm of leather II, which may be also attached at its centre to the crown
of its dome. This part of the invention is applicable to other mercurial governors.
The gas enters under the high pressure governor at B, and passes partly by the
passage C to the high pressure service pipe, and partly by a passage J (see Fig. 2)
to the space between the two covers G and H, and thence, by an opening K, to the
low pressure service pipe (". The whole governor will be closed in by a suitable
cover L, in which is a small orifice M for the entrance of the external air. A similar
orifice is made at N for the lower governor. Springs or weights will be provided
above the domes E E¹, to regulate the pressure at which the governors work, in the
usual manner.
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 1.
claim.is -
The arrangement of mercurial gas governor herein shown and described, for
controlling simultaneously a low pressure of gas for lighting purposes, and a higher
pressure for cooking and heating purposes as set forth.
