An Improved Gas Regulator.
I, FREDERICK WILLIAM PARKER, of 151 Strand, Middlesex, Patent Agent, (a
communication to me from abroad by William C. Rossney of Hyde Park, Boston,
Massachusetts, United States of America, Inventor,) do hereby declare the nature
of this invention to be as follows:-
--
This my invention relates to a new and improved gas-regulator and it consists of
the parts and combination of parts as hereinafter set forth.
In this my invention I provide an outside body or casing, which preferably consists
of a circular vessel or receptacle of convenient height, having a suitable lid.
At a short distance below the upper inside edge of the body or receptacle is cast
or otherwise formed a suitable channel capable of holding a liquid. A dome-shaped
piece of metal having a circumferential flange which rests within the channel afore-
said, containing a liquid, serves to retain the gas in the body or casing, and will rise
or fall according to the pressure of gas.
Within the outside body or casing is an inner casing or receptacle centrally situated
upon the bottom of, and similar to the outside casing, and also adapted to contain a
liquid in a channel formed for that purpose. A similar dome-shaped piece of metal to
that aforedescribed rests in the liquid and channel in the inner casing. These two
domes are connected by a stem or rod which passes centrally through the lids of the
inner and outer casings, and carries upon it, midway between the two domes a circular
disc. The inlet pipe enters the outer body or casing in the bottom thereof and its
orifice has formed around it a channel containing a liquid in which rests a dome-
shaped valve. This valve is connected by a vertical rod to a horizontal and balanced
lever pivoted centrally to a suitable bracket. The end of the balanced lever not
pivoted to the last named vertical rod is provided with a roller which rests upon the
disc of the vertical rod which connects the two central domes as aforedescribed. I
provide a small pipe which extends from the inlet pipe into the interior of the inner
casing which serves to equalize the pressure of gas. The outlet pipe is situated in the
side of the outer casing.
In an alternative form of my invention in which, as before, I employ an outer body
or casing, formed with a channel containing liquid and a dome resting therein, I
divide the outer body or casing near its lower end into an upper and lower, com-
partment.
Opening into the lower compartment is a liquid valve similar to that aforedescribed,
and opening into the upper compartment on the opposite side of the division is a like
liquid valve. These two valves are connected by vertical rods to a balanced horizontal
lever pivoted to a suitable bracket. The horizontal lever passes through a suitable
yoke forming part of a vertical rod connected to the dome of the outer casing. The
inlet pipe enters beneath the division of the body or casing, and the outlet pipe enters
above the division.

An Improved Gas Regulator.
I, FREDERICK WILLIAM BARKER, of 151 Strand, London, Middlesex, Patent Agent.
do hereby declare the nature of this invention, (a communication to me from abroad.
by William C. Rossney, of Hyde Park, in the County of Norfolk, and State of
Massachusetts, United States of America, 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 gas regulators, for the purpose of auto-
matically regulating and controlling the supply of gas delivered to the burners
independent of the pressure in the gas main or supply pipe leading from it to the
regulator.
The invention is carried out as follows, reference being had to the accompanying
drawings wherein :-
Figure 1 represents a vertical section of my improved gas-regulator, some of the
parts being shown in elevation.
Figure 2 represents a cross-section on the line X Y shown in Figure 1.
Figure 3 represents a vertical section of a modified form of my invention, some of
the parts being shown in elevation.
Figure 4 represents a cross section on the line ay shown in Figure 3, and
Figure 5 represents an enlarged detail sectional view of the yoke by which the
gas-holder is connected to the valve-lever.
Similar letters refer to similar parts wherever they occur on the different parts of
the drawings.
In the drawings a represents the casing or body of the regulator, having base or
bottom a¹ and detachable cover a².
On the interior of the casing a is an annular cylinder a³, containing mercury or
quicksilver b.
c is the gas-holder, made in the form of an inverted cup, the lower edge of which is
sealed in the liquid b in the cylinder a³.
The cover a2 has a central perforation, in which is loosely guided the rod d, that is
adjustably secured to the gas-holder e in a gas-tight manner.
e is the gas-supply pipe leading from the main or other gas-supply to the lower
part of the interior of the body or casing a, and f is the delivery pipe leading from
said case a to the burners.
g is a valve adapted to close and open the supply-pipe e, it being shown as made in
the form of an inverted liquid seated cup, the lower edge of which is shown sealed in
the liquid h, contained in the valve-seat i.
G is the valve stem or rod of the valve 9, its upper end being adjustably connectedi
to the weighted lever K, that is pivoted to the adjustable fulcrum bar or bracket 1,
that is secured in a suitable manner to the case or body a, as shown.
kis the weight, adjustably secured in a suitable manner to the lever K, as shown.
To the weighted end of the lever K is journalled the wheel or roller k¹, which by the
influence of the weight k is made to press and rest on the top of a disc d', that is
secured to the gas-holder stem d, as shown.. The lower end of said stem d is guided
in a vertical pipe a secured to the bottom or base a', as shown in Figure 1.
To the stem d, near its lower end, is secured an inverted cup-valve D, which is of a
size equal to that of the valve g, and said valve D has its lower edge constantly sealed
in the liquid m, preferably mercury or quicksilver, contained in the valve-case or
cylindrical cup M, secured to the interior of the base a', as shown.
M' is a cross-bar or cover secured to the top of the cup M, it having a central
perforation, through which the stem d passes loosely and in which it is guided.
o is a small pipe or channel leading from the supply-pipe e to the interior of the
cup M below the valve D, as shown in Figure 1.
It will thus be seen that the valves g and D, being of equal size and actuated by the

page_text: same gas-pressure from the supply-pipe e, are balanced and are actuated independent
of the pressure in said main or supply pipe e. We will suppose the gas-holder c. and
the constantly sealed cup-valve D to be in their highest positions, as shown
in Figure 1, and the valve g closed. If the pressure of the gas within the regulator
be now reduced by the opening of one or more burners leading from the pipe f, the
gas-holder c descends, causing a downward movement of its stem d, disc d', and
liquid-seated valve D, and by the gradual descent of the disc d' the weight on the
lever K causes the roller k¹ to partake of the movement of said disc d' and thereby
trips the lever K and causes the valve g to open for the admission of gas to the regu-
lator from the pipe e. As long as the consumption of the gas is equal to the supply
the valve g will remain open; but if the consumption should be lessened by the
shutting off of one or more burners communicating with the pipe the holder c will
rise, and in so doing its disc d' will gradually move the weighted lever K to the
position shown in Figure 1, thereby closing the valve 9. The valve g will remain
closed until the gas-pressure in the body a is lowered, when the holder e will descend,
and thus cause a gradual opening of the said valve, and so on.
The disc d' enables the holder c, its valve D. and stem d to be turned freely around
without disconnecting the roller k¹ from said disc d'.
In the modification shewn in Figs. 3-5,
A' is a horizontal division wall in the body a and between it and the bottom a¹ is
the valve-box A, as shown in Figure 3.
g g² are perforations in the valve-box cover or division wall A¹, which perfora-
tions are adapted to be closed by means of a pair of balance valves and the
stems or rods H H of which are suitably connected to the lever I that is pivoted
at to the rod or standard 2 that is secured in a suitable manner to the valve-
box cover A. To the lever I is adjustably secured the weight W for the purpose
of balancing the valves h¹ and h². The rod or bearing 2 is preferably screwed
into one of the screw-threaded recesses a in the top of the valve-box cover A',
so is to adjust it relative to the valve as may be desired.
The valve is shown as made in the form of an inverted cup, the lower edge
of which is shown as closed in the mercury or quicksilver 1, contained in the cup-
shaped valve-seat m¹. The valve h¹ is shown as being made in the form of a cup
containing mercury or quicksilver 1, and as said valve is raised the stationary
valve-seat m² is caused to be sealed in the liquid contained in said cup-shaped
valve h¹.
I desire to state that I do not wish to confine myself to any particular con-
struction of the said balance or equilibrium valves, as they may be liquid seated or
hard seated, although in practice I prefer to use liquid-seated valves, as shown in
the drawings.
The gas-holder spindle d is jointed in its lower end to the valve-lever I in the
following manner :
N is a slotted frame or yoke, to the upper end of which the gas-holder spindle d
is loosely connected or swivelled, as so to permit the gas-holder c and its spindle d
to turn around more or less independent of the said yoke or frame N, and for this
purpose any suitable swivel connection may be used between said rod and the yoke
or frame N. In the drawings Figures 3 and 5, I have shown the lower end of the
rod d as projecting loosely through a vertical perforation in the upper end of the
yoke or frame N with nuts or collars n' n² secured to the said rod d above and below
the upper wall of the yoke N, but any suitable connecting mechanism may be used
without departing from the essence of my invention.
To the lower end of the yoke N is secured the spindle that is guided in the
vertical pipe or guide a, secured in a suitable manner to the division-wall A¹, as
shown in Figure 3.
The lever projects loosely through the slotted fraine or yoke N, and above and
below said lever are located the anti-friction rollers p and q, that are loosely journalled
on the pins p¹ and 9', passing through the sides of the said yoke N as shown in
Figure 5.

It will thus be seen that the vertical movement of the gas-holder c and its spindle d
is communicated directly to the lever I and its valves h¹ and h² and the object of thus
connecting the gas-holder to the weighted lever is to automatically compensate for the
variations in the displacement of the liquid seal b in the cylinder a³ during the rise.
and fall of the said gas-holder, and thus cause the valves to be automatically balanced
during such variations in the positions of the said gas-holder.
We will suppose that the gas-holder c is in its highest position, the valves h³ ³
closed, and the lever I in the horizontal position, as shown in Figure 3. If, now, the
pressure within the gas-holder should be reduced by the consumption of the gas
passing out through the pipe f, that leads to the burners, the gas-holder c will
commence to move downward, thereby causing the lever I to swing on its fulcrum i¹
until the valves ¹² are opened, when the gas from the pipe e and valve-box A will
pass into the body a and out through the pipe f, that leads to the burners, and will
continue so to do as long as the consumption of gas is equal to the supply. Wben,
however, the consumption is reduced by the shutting off of one or more burners, the
holder c will rise, and by so doing it will cause the lever I to be returned to its
horizontal position (shown in Figure 3) and consequent gradual closing of the
valves h¹ thereby shutting off the supply of gas from the pipe e.
During the downward movement of the holder c its annular lower edge displaces
a certain quantity of the mercury b, and consequently reduces the weight of said
holder, but such reduction in weight is compensated for by the increased leverage on
which the said holder acts on the lever I during the downward motion of the valve h¹,
for it will be noticed that as the valve ¹ is lowered the distance between the
fulcrum and that part of the lever I on which the rollers p q act is increased, thus
making the static force of the holder c on the weighted lever I and its valves equal
during the various positions of said parts and compensating for the displacement of
the liquid b during the downward motion of the holder c.
When the holder c rises, its weight is increased by the sinking of the mercury
seal b, and such increase is compensated for by the reduction of the leverage on the
lever I on which the yoke or frame N acts, until the normal closed position of the
valves is reached, and so on.
It will also be noticed that the balanced valves h' and 2 are opened and closed
entirely independent of the pressure in the valve-box A or in the supply-pipe e, the
movement of said valves being controlled by the rise and fall of the gas holder c,
according to the consumption of the gas at the burners.
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
