PROVEMENTS IN APPARATUS FOR REGULATING THE PRESSURE AND SUPPLY OF
GAS."
Sealed the 25th April 1854, and dated the 31st January 1854.
PROVISIONAL SPECIFICATION left by the said Luther Young and Edwin
Marten at the Office of the Commissioners of Patents, with their Petition,
on the 31st January 1854.
We, LUTHER YOUNG, of 8, Bow Lane, Cheapside, and EDWIN MARTEN, of
19, Louisa Street, Stepney, do hereby declare the nature of the Invention
for "IMPROVEMENTS IN APPARATUS FOR REGULATING THE PRESSURE AND SUPPLY OF
GAS" to be as follows:-
This Invention consists of a combination of mechanical parts into an appa
ratus to regulate the pressure and supply of gas. For this purpose, a valve is
suspended to the shorter end of a lever, such valve being caused, more or less,
to close or open the passage by which the gas is supplied; the other or longer
end of the lever is connected by a rod to an inverted vessel which dips into'
water or other fluid, and such vessel is made to float by means of one or more
floats, in a tube or tubes containing quicksilver or other fluids, and the exact

page_text: pressure is obtained by weights applied to the inverted vessel. The gas coming
to the apparatus, subject to more or less excess of pressure, raises the inverted
vessel to such an extent as to close the valve to the degree which will admit
of the quantity of gas required for the consumption passing at the pressure
desired. And where the several burners are at different elevations, or require
different degrees of pressure of gas, I make partitions with different sizes of
orifices, and apply the same to the burners, by which only the desired quantity
of gas will pass at the particular pressure to the burners.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Luther Young and Edwin Marten in the Great Seal Patent
Office on the 31st July 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, LUTHER
YOUNG, of 8, Bow Lane, Cheapside, and EDWIN MARTEN, of 19, Louisa Street,
Stepney, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of January, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Luther Young and Edwin Marten, Her special licence that we, the
said Luther Young and Edwin Marten, our executors, administrators, and
assigns, or such others as we, the said Luther Young and Edwin Marten,
our executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
REGULATING THE PRESSURE AND SUPPLY OF GAS," upon the condition (amongst
others), that we, the said Luther Young and Edwin Marten, by an instru-
ment in writing under our hands and seals, or under the hand and scal of
one of us, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months.
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Luther Young and Edwin Marten,
do hereby declare the nature of the said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:-
This Invention consists of a combination of mechanical parts into an appa-
ratus to regulate the pressure and supply of gas. For this purpose, a valve is
suspended to the shorter end of a lever, such valve being caused, more or less,
to close or open the passage by which the gas is supplied; the other or longer
end of the lever is connected by a rod to an inverted vessel which dips into
water or other fluid, and such vessel is made to float by means of one or more
floats in a tube or tubes containing quicksilver or other fluids, and the exact
pressure is obtained by weights applied to the inverted vessel. The gas coming
to the apparatus, subject to more or less excess of pressure, raises the inverted
vessel to such an extent as to close the valve to the degree which will admit
of the quantity of gas required for the cousumption passing at the pressure
desired. And where the several burners are at different elevations, or require
different degrees of pressure of gas, we make partitions with different sizes of
orifices, and apply the same to the burners, by which only the desired quantity
gas will pass at the particular pressure to the burners.
of
Having thus stated the nature of the said Invention, we will proceed to
describe the manner of performing the same.
of
DESCRIPTION OF THE DRAWING.
Figure 1 shows a section of apparatus for regulating the pressure and supply
gas, which is arranged suitable for being screwed on to a supply pipe at the
ends a and b. The gas flowing in at a will be regulated by the valve c, which
is suspended to the shorter end of the lever d, which at its other end is con-
nected to the inverted vessel e, which dips into the fluid f, and the pressure of
the gas in the vessel e will govern the extent to which the valve c is opened.
When the supply becomes too great, the pressure of the gas in raising the
vessel e, will cause the valve to be partly closed, and the reverse will take
place when the supply falls off as compared with the consumption. When the
vessel e is balanced by the weight of the valve c, the lever may be connected
by a rod g, directly to the vessel e; but when the valve cannot be made suffi-
ciently heavy, it is desirable to employ a float or floats h, in a vessel i, con-
taining quicksilver, such vessel i being fixed to the interior of the vessel j', in
which case the rod g is to be branched, as shewn by red lines.
Figure 2 shows a section; and Figure 3, an end view of a partition, with a
hole of a determined size in it. By the use of such partitions in the tubes of
gas burners, such partitions having holes of different sizes, according as par-

page_text: ticular burners on the same service are at different elevations, the flow of gas
to the burners will be regulated.
Having thus described the nature of the said Invention, and the manner of
performing the same, we would have it understood that what we claim is, the
combined apparatus herein described.
In witness whereof, we, the said Luther Young and Edwin Marten, have
hereunto set our hands and seals, this Thirty-first day of July, in the
year of our Lord One thousand eight hundred and fifty-four.
