page_text: I THOMAS ROBINSON of Manor House, Farnley near Leeds in the County of
York Manufacturer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to regulate the pressure of gas between the supply
pipe and the burners.
In my regulator I provide an inlet chamber to which the gas is first admitted
and a valve controlling the passage between this chamber and a second chamber
which contains a float supported upon water or other liquid and suitably guided.
This float is attached to the valve. The second chamber is connected with the
gas outlet and also near its lower end it is in free communication with a third
chamber open to the air. This third chamber may conveniently receive the second
chamber within it.
The pressure of gas in the second chamber depresses the water level therein and
raises the water level in the third chamber.
As the water level in the second chamber falls the float also descends taking the
valve with it and thereby checking the flow of gas into the second chamber and
thence in the outlet pipe.
An index finger is connected with the float, it shows on a scale the pressure
within the second or float chamber. The quantity of liquid should be so adjusted
that when the gas is turned off from the regulator this index finger stands at zero
of the scale.
The form of the valve may be varied I sometimes use a cone valve and some-
times an hydraulic valve dipping down into water or liquid.
The sides of the bell are perforated and as the bell descends into the liquid the
perforations are successively covered.
The indicating finger may be attached above the valve and be seen within the
inlet chamber through a glass provided for the purpose. Or the finger may be
attached at the lower part of the float and rise up through the liquid in the third
chamber.
In this case the scale may be attached to the exterior of the apparatus and it is
not necessary that it should be enclosed.

manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-

In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of a gas regulator constructed in accordance with
my invention.
Figure 2 is an elevation of the same.
Figures 3 and 4 are sections through a portion of the apparatus showing valves
of other forms.
Figure 5 is a vertical section of a regulator in which an hydraulic valve is
employed.
Figure 6 is an elevation of this regulator.
Figure 7 is a section and Figure 8 is a plan of an hydraulic valve of another
form.
In Figures 1 and 2 a is the first or inlet chamber which receives the gas as it
enters from the service pipe at b and in it is the valve c past which the gas flows
from chamber a to the second chamber d; a pipe attached to this chamber at d¹
passes to the burners.
The dotted lines indicate the position of the valve
to the largest quantity of gas to pass. The valve is
is when the pressure in the chamber d is sufficient.
when open and giving liberty
also shewn nearly closed as it
When the pressure is shut off

page_text: from the chamber a the valve rises and the lower disc c¹ may be arranged under
these circumstances to close against the under side of the valve seat.
The float e in chamber d rides on the water and it has attached to it the spindle
on which the valves c c¹ are fixed. The spindle is continued up through an opening
at the top of the chamber a and may be seen entering a glass test tube through
which it may be examined and the variations of opening and closing of the valves
observed.
The chamber d containing water or other liquid communicates freely with a
third or tank chamber f. As the gas enters from the chamber a and presses on the
water contained in the chamber d the water descends and rises in the tank
chamber which encircles the chamber d and any variation of pressure of gas
causes the water to rise or fall in the chamber d.
Within the tank chamber f a long float g may be provided that rises and falls
with the variation of the water level. The upper portion of this long float enters
a tube h and projects beyond it for observation as it also will shew the rise and fall
of water which governs the opening and closing of the valve. Or an indicating
stein attached at the bottom of the float a may ascend and pass out through the
tube h.
The action of this regulator is such that when gas presses on the water or other
liquid in chamber d the liquid descends and enters the chamber f and as the float
rises and falls with the water in the chamber d; it opens and closes the valve and
so regulates the feed passing through the apparatus.
ii are plugs in the side of the tank chamber f for drawing off the liquid to a
suitable level.
Figures 3 and 4 show valves of such forms as to give a greater range of action
between the commencement of the cut off and the closing of the valve.
Figure 2 is this apparatus as seen outside and Figures 3 and 4 are other shapes
or forms of valves which may be substituted for the one shown in Figure 1.
Figures 5 and 6 show a gas regulator differing from Figure 1 by having a domed
perforated hydraulic valve C in the chamber a this domed valve rises and falls by
the action of the float in the chamber d.
The perforated valve encircles a pipe or passage by which the gas admitted at b
and flowing through the holes in the valve C enters the chamber d. The holes
standing above the liquid in the chamber a are alone available for the passage of
the gas and as the float descends with the increase of pressure in the chamber d
the number of holes uncovered is diminished and the flow of gas is checked. In
place of a perforated dome a dome with slits in it may be employed as shewn in
Figure 7. Figure 8 is a plan of this dome valve.
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 combination in a gas regulator of the chambers a, d and f the float e
and the valve c substantially as described.
2. The use in the said combination of a domed hydraulic valve with perforations
or slits substantially as described.
3. My improved gas regulators substantially as described and represented by
the annexed drawings.
