page_text: I GEORGE PORTER of No. 23 Cullum Street, in the city of London, Engineer do
hereby declare the nature of this invention to be as follows:-
:―
This invention relates to improvements in mercurial gas regulators or governors
and has for its object the prevention of oscillation of the burners common to other
regulators, more perfect equilibrium action of the valves and consequently greater
accuracy and sensitiveness thereof, dispensing to a great extent with counter
balance weights; prevention of escape of gas by means of an extra valve which
shuts off automatically in case of loss of mercury from any cause, or accident to
the governor; constructing the shell or body of the governor in several parts and
mounting the valves on a separate base in order that the other parts may be easily
removed by any ordinary person so as to leave the valves entirely exposed for
cleansing, adjustment or other necessary purpose such provision not being generally
made in other governors.
According to my invention the valves in the lower part of the regulator are of
the equilibrium form but instead of the two valves being mounted in a single
chamber as heretofore I mount them in a double chamber, each of the said chambers
being fitted with a separate inlet which equalizes the pressure and thus ensures
perfect equilibrium action; the gas acting with equal force upon the lower and
upper valve instead of rushing with greater force out of the upper one; in this
latter case causing the valves to oscillate under certain pressures and thereby
imparting unsteadiness to the burners.
An additional valve is fitted to the upper part of the same spindle and this
additional valve works in a seating provided for it in the roof of the lower valve
chamber, the object of this being, that, should there be a loss of mercury from any
cause the diaphragm would cease to float and the upper valve would thereby fall
into its seating and thus shut off the gas which would otherwise escape into the
house.
The body or outer shell is constructed in several pieces; the base with the inlet
and outlet pipes attached is in one separate piece and upon this is mounted the
equilibrium valve, the body and upper part are also in separate pieces and the
whole placed together and secured by clips, bolts or screws.

page_text: Improvements in Gas Regulators or Governors.
I, GEORGE PORTER of No. 23 Cullum Street, in the City of London, 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 improvements in mercurial gas regulators or governors
and has for its object the prevention of oscillation of the lights common to other
regulators, more perfect equilibrium action of the valves and consequently greater
accuracy and sensitiveness thereof, dispensing to a great extent with counter
balance weights, the valves acting with such precision that not only is a saving
effected under a high pressure but under a low pressure also; prevention of escape
of gas by means of an extra valve which shuts off automatically in case of loss of
mercury from any cause, or accident to the governor, and controls the meter so as
not to allow more gas to pass than each burner when alight actually requires con-
structing the shell or body of the governor in several parts and mounting the valves
on a separate base in order that the other parts may be easily removed by any
ordinary person so as to leave the valves entirely exposed for cleansing, adjustment
or other necessary purpose, such provision not being generally made in other
governors.
According to my invention the valves in the lower part of the regulator are of the
equilibrium form but instead of the two valves being mounted in a single chamber
as heretofore I mount them in a double chamber, each of the said chambers being
fitted with a separate inlet which equalizes the pressure, and thus ensures perfect
equilibrium action; the gas acting with equal force upon the lower and upper
valves instead of rushing with greater force out of the upper one; in this latter
case causing the valves to oscillate under certain pressures and thereby imparting
unsteadiness to the lights.
An additional valve is fitted to the upper part of the same spindle and this
additional valve works in a seating provided for it in the roof of the lower valve
chamber, the object of this being, that, should there be a loss of mercury from any
cause the diaphragm would cease to float and the upper valve would thereby fall
into its seating and thus shut off the gas which would otherwise escape into
the house.
The body or outer shell is constructed in several pieces; the base with the inlet
and outlet pipes attached is in one separate piece and upon this is mounted
the equilibrium valve, the body and upper part are also in separate pieces and the
whole placed together and secured by clips, bolts or screws.
In order to enable my invention to be fully understood I will proceed to describe
the same, by reference to the accompanying drawing in which figure 1 represents
a vertical section of a gas regulator or governor constructed according to my
invention; figure 2 is a vertical section of the same partly in elevation, the
section being taken transversely to figure 1, and figure 3 is a horizontal section

page_text: taken on the crooked line A B of figure 1. Similar letters in all the figures
represent similar parts.
a, and b, are the two valves of the equilibrium form in the lower part of the
regulator; c and d, represent the double chamber in which the said valves are
mounted on the lower part e of a spindle made in two parts e and c¹; f, is the
opening controlled by the valve a, through which the gas entering the chamber c,
from the inlet pipe g, through the inlet h, passes into the lower part A of the
regulator; i, is the opening controlled by the valve b, through which the gas
entering the chamber d, from the said pipe g, through the separate inlet j, passes
into the said part A of the regulator, this arrangement sorving to equalize the
pressure and causing a perfect equilibrium action in the manner herein before
explained; k, is the additional valve fitted to the upper end of the part e, of the
spindle, and b, is the seating of the said valve provided in the roof of the part A
of the regulator forming the lower valve chamber, the edges of the said seating
being turned over in the manner shown in the drawing in order to prevent the
mercury from entering the lower part A of the regulator in the event of the
apparatus becoming inverted during transit; m, is the diaphragm fixed to the
valve k, and floating in mercury placed in the lower portion A of the regulator as
shewn, the valve serving in the manner hereinbefore explained to shut off the gas
from the diaphragm m, in case of the latter ceasing to float through a loss of
mercury from any cause; m³, m³, are weights which are placed on the upper
part c, of the spindle to equilibrate the valves, the said part c¹, of the spindle
working through a sleeve or guide d, on the top of the upper portion B of the
regulator as shewn in figure 1; the part c¹, of the spindle is formed triangular in
cross section and with a plate c¹, at its lower end so that the latter can at all times
work freely in the sleeve or guide d', a set screw f¹, being provided which by
entering the sleeve or guide d', between the angles of the part c' of the spindle
will prevent the latter from falling out of the apparatus if it be inverted, the upper
end of the part e of the spindle bearing upon the plate c¹, when the valve k, is
raised. By forining the spindle in two parts in the manner herein before described,
I prevent the weights from throwing the part of the spindle carrying the valves
out of tho perpendicular, and the valves are consequently caused to work accurately
in their seatings; n, is a cover by removing which access is obtained to the said
weights o, represents the outlet for the gas to the burners after having passed
through the regulator or governor, the said gas entering the outlet through an
opening b¹, in the base p, hereinafter referred to. The drawing will serve to
illustrate my method of constructing the shell or body A. B. of the regulator in
several parts and mounting the valves on a separate base p, formed with or
attached to the inlet and outlet pipes g, and o, the whole being placed together
and secured by nuts q, and bolts 7, (or by elips or other suitable means) whereby
the parts can be easily removed for cleansing or other purposes as herein before
described.
The course of the gas through the regulator or govenor is indicated by the
arrows in figures 1 and 2; as the gas enters the separate chambers c, and d, from
the inlet g, and passes out therefrom into the lower part A of the shell or body of
the regulator the pressure of the gas upon the diaphragın m, will always keep
open the valve ; if the burners be turned off the pressure of the gas will raise the
diaphragm m, to such an extent as to close the valves a, and b, the gas in this
manner being prevented from entering the lower part A of the regulator. If how-
ever the burners or some of them be turned on, the pressure upon the diaphragm m,
will be proportionately reduced and sufficient gas will be allowed to pass to supply
the number of burners lighted. For every burner which is turned off or on, or on
any increase or decrease of the pressure in the street mains a corresponding closing
or opening of the valves a, and b, takes place. This action of the governor, which
is entirely automatic, produces a uniform pressure at the point of incandescence, so
that a great saving is effected in the consumption of gas.

page_text: 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. A gas regulator or governor having its valves which are of the equilibrium
form mounted in a double chamber each of which chambers is provided with a
separate inlet substantially as and for the purposes herein before described and
represented in the accompanying drawing.
2. In a gas regulator or governor the combination with a double chamber in
which the two valves a, and b, of equilibrium form are mounted, of a third valve k,
fitted to the same spindle and carrying the diaphragm m, substantially as and
for the purposes hereinbefore described and represented in the accompanying
drawing.
3. In a gas regulator or governor making the spindle carrying the regulating
valves in two parts the lower part carrying the valves, and the upper part carrying
the equilibrating weights substantially as and for the purposes bereinbefore
described and represented in the accompanying drawing.
4. The improved gas regulator or governor herein before described and represented
in the accompanying drawing.
