PROVISIONAL SPECIFICATION.
Improved Means for Regulating Gas Pressure in Incandescent Gas
Lighting.
1, WILLIAM THOMAS SUGG, .of Vincent Works, Regency Street, Westminster,
S.W., Engineer, do hereby declare the nature of this invention to be as follows:-
It is now well known that the best results are obtained in incandescent gas
lighting by using the gas under pressure, the most suitable pressure for the
purpose being about nine inches.
The pressure is most conveniently obtained by means of a water-driven pump
or compressor, the speed of which should be regulated according to the number
of lights. For this purpose, means have been provided to cut off the water supply
when a certain pressure is exceeded, and to turn it on again when that pressure
is diminished, but such means are not entirely satisfactory, and the object of
this invention is to provide a simple and efficient apparatus for effecting the
purpose mentioned.
In carrying out this invention, I employ two vessels, which I will term A
and B, having gas-tight covers, and connected together at bottom in any con-
venient manner.
Each vessel is provided with a float, that in the vessel A, which I will term
the gas chamber, being connected with a suitable valve contained in a valve box
on the top of the vessel, while that in the vessel B is connected in any convenient
manner with the water-supply cock.
The pipe for the gas under pressure is connected to the valve box, and the
outlet for the gas is made in the vessel A.
When working both vessels (which will be of the same area) will be filled with
water to a certain height, and the gas turned on.
When the pressure in the gas chamber exceeds requirement, the water therein
will be forced into vessel B. the float of which will rise, and turn off the water
supply to the pump more or less, or entirely.
At the same time, the gas float will descend, and more or less or entirely cut
off the gas supply to the gas chamber and thus, risk of “blowing," through
excess of pressure, will be obviated.
Means may, however. be provided to carry off to the open air any gas that
may blow."

Lighting.
1. WILLIAM THOMAS SUGG, of Vincent Works, Regency Street, Westminster,
SW, 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:
It is now well known that the best results are obtained in incandescent gas
lighting by using the gas under pressure, the most suitable pressure for the
purpose being about nine inches.
The pressure is most conveniently obtained by means of a water-driven pump
or compressor, the speed of which should be regulated according to the number
of lights. For this purpose, means have been provided to cut off the water supply
when a certain pressure is exceeded, and to turn it on again when that pressure
is diminished, but such means are not entirely satisfactory, and the object of
this invention is to provide a simple and efficient apparatus for effecting the
purpose mentioned.
In carrying out this invention, I employ two vessels of equal area, having
gas-light covers, and connected together at bottom in any convenient manner.
Each vessel is provided with a float-one being connected with a suitable valve
on the top of the vessel, while the other is connected, in any convenient manner,
with the water supply cock. Suitable inlet and outlet pipes for the gus under
pressure are provided.
In the accompanying drawings I have shown one mode in which the inven
tion may be conveniently carried out.
Fig. being a side elevation of the compressing apparatus, with the means for
regulating gas-pressure in section, and
Fig. 2 is a cross section of the means for regulating gas pressure, taken above
the floats.
A is a vessel, and B a second vessel, of equal area, connected together at the
bottom. For convenience, these vessels are shown one inside the other, and
both are made gas-tight.
C represents a water motor, and D a compressor. E is the pipe from the
water reservoir, and E is a cut-off device of any suitable character. by which
the supply of water to the motor is automatically arrested, as will be presently
described.
The gas enters the compressor by the pipe G, and passes out to the regulating
device by the pipe H. The gas enters the vessel A near the top, and passes
out at to the installation. K is a pipe by which any gas that might "blow **|
through the water in the vessels A and B may escape to the outer air.
L, L, are two floats, with suitable guide rods, and which are placed in the
vessel A. The lower rods are steadied by guides, while the upper rods pass
through openings in a horizontal partition, forming seats for conical valves
carried by the float guide rods.
M is a single float with suitable guide rods contained in the vessel B. The
upper rod passes through a gland in the top of the vessel, and is connected to a
lever intended to operate the cut-off device for the water supply.
When it is desired to work the apparatus, both vessels will be filled with water
to a certain height, and the gas cocks to the several burners of the installation
turned on.
The apparatus will at once commence to work, because the pressure will be

page_text: relieved, the float M will descend, and, by its weight, open the cut-off device F
for the water supply.
When, owing to the continuous pumping, the pressure in the vessel A exceeds
requirement, the water therein will be forced into vessel B, the float of which will
rise, and turn off the water supply F to the pump more or less, or entirely.
At the same time, the gas floats in A will descend, and the conical valves will
more or less, or entirely, cut off the gas supply to what may be termed the gas
float chamber of A, and thus all risk of blowing" from the vessel B, through
any great excess of pressure, will be obviated.
"
"
By the expression means for regulating gas-pressure," I wish to be under-
stood, in the present connection, a device, or series of devices, which will auto-
matically throttle the supply of power to a motor so soon as the pressure in a
reservoir into which the gas is being pumped by the operation of the motor,
exceeds a certain limit, and which will automatically operate to open the supply
of power to the motor, so soon as the pressure decreases.
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:
-
1. The means for regulating gas pressure in incandescent gas lighting, and
consisting of two gas-tight vessels of equal area, to contain water, and connected
at bottom-one vessel to receive gas under pressure, and the other to contain a
float connected to a cut-off device, an excess of pressure in the gas vessel forcing
the water into the other vessel, so as to raise the level of water therein, and
raise the float, which thus operates the cut-off device, as herein shown and
described, and for the purpose set forth.
2. In combination with the means described in Claim 1, a float or Hoats in
the gas vessel carrying a conical valve or valves arranged to close openings in a
horizontal partition in the gas vessel, as shown and described, and for the purpose
set forth.
8. The entire combination of apparatus for use in incandescent gas lighting, as
herein shown and described with reference to Fig. 1 of the drawing.
