page_text: I, WILLIAM THOMAS SUGG, of Vincent Works, Regency Street, Westminster,
London, S.W., do hereby declare the nature of this invention to be as follows:-
This invention relates to that class of apparatus in which gas is compressed by
means of water power, the object of the invention being to provide a simple and
efficient means for compressing the gas, and for regulating the flow of water to the
motor, according to requirements.
The compressor consists of a cylinder having passages in the walls. One of these
passages connects with the inlet, and the other with the outlet.
At each end of the cylinder are two valve boxes, one of which contains an inlet
valve and the other an outlet valve.
The piston
somewhat loose-fitting, and carries two or more washers of leather or
other suitable material, to make it sufficiently tight to prevent the gas passing.
The piston operates in both directions.
The gas, as it passes from the compressor, enters a specially-constructed governor,
which is arranged to admit of a maximum pressure of 9 inches.
The gas first passes to a chamber in which is a partition with an opening closed by
a conical valve carried by a lever.
From this chamber the gas passes to another, in the top of which is an opening
closed by a conical valve, to the rod of which the lever before named is attached.
Above the opening is a loaded flexible governor or disc valve, which will operate
when the lights are increased or diminished, to open or close the valve, as is now
well understood.
From this governor, the gas passes by a suitable passage to another chamber
containing a second flexible governor or disc valve carrying a rod, on the end of which
is a plug valve. At top, this rod is connected to a lever which operates a slide or
other valve in connection with the water supply.
Thus, any increase of pressure due to turning out light, will act on the governors,
to close the water supply to the motor, and any decrease in the pressure will, in like
manner, open the water valve, so that the working of the motor will be dependent on
the number of lights going at any given time.

page_text: Improvements relating to the compressing of Gases.
I, WILLIAM THOMAS SUGG, of Vincent Works, Regency Street, Westminster,
London, S.W., 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 relates to that class of apparatus in which gas is compressed by the
aid of water power, the object of the invention being to provide simple and efficient
means for compressing the gas, and for regulating the flow of water to the motor,.
according to requirements.
In the accompanying drawings,
Fig. 1 is a general view of the improved apparatus ;
Fig. 2 is a vertical section of the compressor;
Fig. 3 is a cross section on the line 1-2 of Fig. 2; and
Fig. 4 is a sectional elevation of the governor mechanism.
A is a direct-acting water motor, of any suitable construction. B is the compressor.
C is the governor mechanism. D is the cut off for the water. E is the water pipe
for the motor. F is the gas inlet to the compressor, and G is the gas outlet from the
governor.
The gas compressor consists of a cylinder B, in the walls of which are
passages HH-the passage H is connected with the inlet F, and the other
passage, H, with the outlet to the governor C. At the opposite ends of the passage H,
are inlet valve boxes J, connected with the cylinder, and containing suitable flap or
other valves, and at opposite ends of the passage H¹ are outlet valve boxes K, also
connected with the cylinder, and containing suitable valves, as before.
The inlet valves are arranged to open as the compressor piston recedes, and close
as the piston approaches, while the outlet valves are arranged to operate in the
reverse manner.
Lis the compressor piston, the rod of which is connected directly to the piston rod
of the motor A.
The piston L, which operates in both directions, is loose fitting, and is provided
with one or more leather or other washers, to make it sufficiently tight to prevent
the gas passing.
The gas may pass direct to the installation from the compressor, but inasmuch as,
under certain circumstances, the pulsations of the compressing mechanism may be
felt, and also the pressure may increase too much, I find it desirable to provide a
governor mechanism which will ensure a steady flow of gas, and which will also,
in case of need, operate a cut-off device, by which the supply of water to the motor
will be more or less, or altogether stopped, according to the requirements for the time
being.
The gas, then, as it passes from the outlet passage H¹ of the compressor, will enter
the governor mechanism C.
This mechanism consists of a chamber M, in which is a partition N, an opening
in which is provided with a valve seat for a conical valve O, carried at one end of a
lever P.
This chamber is connected with another chamber, Q, in the top of which is an
opening closed by a conical plug valve R, the rod of which is connected with the other
end of the lever P.
Above this opening is a flexible diaphragm (or, it may be, a floating disc governor S,
the diaphragm of which is connected to the rod of the valve R, and is loaded to any
extent required.
This governor S is connected by the passage T with another chamber, in the

page_text: top of which is an opening provided with a seat for another plug valve, the rod U
of which is connected to another diaphragm governor, V, also adapted to be
loaded.
This rod U passes out through the top of the casing C, and is connected with
a cut-off, as will be presently described.
From the governor V is a passage connected with the outlet G to the instal-
lation.
The rod U is connected to one arm of a lever W, the other arm being connected
with a slide valve X, contained in the chamber D, or with any other suitable cut-off
mechanism adapted to cut off the supply of water to the motor.
The operation of this governor is as follows:-Suppose the installation shut off
at G, and the water flowing to the motor, the motor will work to compress the gas
in B, and drive it into C.
As the gas cannot get away, the pressure will be so increased in C, that the
governors V and S will be caused to rise, in one case operating the cut-off D, and, in
the other, closing the inlet valve O to the governor mechanism C, so that the use of
water will be prevented, and the risk of accidents due to high pressure will be
obviated.
Thus, any increase of pressure due to turning out lights will act on the governors
to close the water supply to the motor, and any decrease in the pressure will, in like
manner, open the water valve, so that the working of the motor will be dependent on
the number of lights going at any given time.
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 apparatus relating to the compressing of gases, the compressor constructed,
arranged, and operating as herein shown and described.
2. In apparatus relating to the compressing of gases, the governor mechanism
constructed, arranged, and operating as herein shown and described, and for the
purpose set forth.
3. In apparatus relating to the compressing of gases, a water motor, the gas com-
pressor, the governor mechanism, and a cut off device, all combined, arranged, and
operating as herein shown and described, and for the purpose set forth.
