IMPROVEMENTS IN WET GAS METERS
Year: 1863

page_text: LETTERS PATENT to Edward Myers, of 2, Millbank Row, County of
Middlesex, Civil Engineer, and William Richard Williams, Meter
Maker, of 35, Lamb's Conduit Street, County of Middlesex, for the
PROVISIONAL SPECIFICATION left by the said Edward Myers and
William Richard Williams at the Office of the Commissioners of Patents,
with their Petition, on the 24th June 1863.
We, EDWARD MYERS, of 2, Millbank Row, County of Middlesex, Civil
Engineer, and WILLIAM RICHARD WILLIAMS, Meter Maker, of 35, Lamb's
Conduit Street, County of Middsex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN WET GAS METERS," to be as follows:-
This Invention relates to a peculiar construction whereby an invariable
water level is maintained in wet gas meters to compensate for loss of water in
the meter.
Fig. 1: A, A, represents the drum case and water line in the same; B, the
reservoir and water line in the same; C, the compartment containing the air
tube and overflow tube. This compartment. has a direct communication with
the drum compartment shewn by the letter J ; D shews the air tube placed a
little below the water line so as to effect a seal between the reservoir and the
meter; E, the overflow tube. The air tube D and the overflow tube E are
connected together and pass through stuffing boxes F & G; H, the screw
F&G;

page_text: connected with the air tube and overflow tube. This screw is for the purpose
of elevating or lowering the air tube and overflow tube for the purpose of
registering the capacity of the meter from the exterior. The least loss of water
in the drum case allows air or gas to ascend the air tube D into the reservoir B,
and causes the water to pass from the reservoir through the orifice K into the
drum case A, A, until the water reseals the air tube D. L represents the
valve and valve box; M, the float connected to the valve rod, which passes
through the tube N. The gas enters the inlet pipe T and passes through the
valve L, down the tube S into the compartment O, and ascends the tube P into
the drum or measuring chamber, and through the aperture J into the compart-
ment C and out of the pipe U. Q, the waste water plug; R, a bucket which is
continually full of water to prevent the gas ascending the overflow tube E.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Myers and William Richard Williams in the Great
Seal Patent Office on the 24th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
MYERS, of No. 2, Millbank Row, County of Middlesex, Civil Engineer, and
WILLIAM RICHARD WILLIAMS, Meter Maker, of 35, Lamb's Conduit Street,
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of June, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Edward Myers and William Richard Williams, Her special
licence that we, the said Edward Myers and William Richard Williams, our
executors, administrators, and assigns, or such others as we, the said Edward
Myers and William Richard Williams, 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 In-
vention for "IMPROVEMENTS IN WET GAS METERS," upon the condition (amongst
others) that we, the said Edward Myers and William Richard Williams, our

page_text: executors or administrators, by an instrument in writing under our or their
bands and seals, or under the hand and seal of one of us or them, 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 I, the said Edward Myers, on behalf of myself
and the said William Richard Williams, do hereby declare the nature of the
said Invention, and in what manner the same is to be performed, to bo
particularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention relates to a peculiar construction whereby an invariable
water level is maintained in wet gas meters to compensate for loss of water in
the meter.
Figure 1 shows a front view of a wet gas meter arranged and constructed
according to our Invention, the front plate being removed in order to show the
internal arrangement of the parts.
A, A, represents the drum case and water line in the same; B, the reservoir
and water line in the same; C is the compartment containing the air tube and
the overflow tube. This compartment C has a direct communication with the
drum or measuring compartment J; D shews the air tube placed a little below
the water line so as to effect a seal between the reservoir and the meter or
measuring chamber; E is the overflow tube. The air tube D and the overflow
tube E are connected together and pass through stuffing boxes F and G; H is
the screw connected with the air tube and overflow tube, this screw is for
the purpose of elevating or lowering the air tube and overflow tube for the
purpose of registering or determining the capacity of the meter from the
exterior, and when adjusted is secured by a seal or otherwise. The least loss
or deviation of level of water in the drum case or measuring chamber allows
air or gas to ascend the air tube into the reservoir B, and causes the water to
pass from the reservoir through the orifice Kinto the drum case or measuring
chamber A, A, until the water reseals the air tube D. L represents the
valve and valve box; M, the float connected to the valve rod, which passes
through the tube N. The gas enters the inlet pipe T and passes through the
valve L, down the tube Sinto the compartment O, and ascends the tube P into
the drum or measuring chamber, and through the aperture J into the con-
partment C and out of the pipe U. Q is the waste water plug; R is a bucket
or chamber which is continually full of water to prevent the gas ascending
the overflow tube E. Figure 2 shows a plan of the meter partly in section.

page_text: A shows the top of drum case; B, the reservoir; C is the compartment con-
taining the air tube and overflow tube; D is the air tube; E, the overflow
tube; H, the regulating screw; I, the charging tube; L is the inlet valve;
M, the float; S, the gas tube; T, the inlet pipe or passage for admission of
gas to meter; U, outlet pipe or passage...
Having thus described the nature of our Invention and the best means we
are acquainted with for carrying the same into practice, we would have it
understood that we do not confine ourselves to the exact details herein
described so long as the peculiar character of our Invention be retained.
In witness whereof, I, the said Edward Myers, have hereunto set
my hand and seal, this Twenty-second day of December, in the year of
our Lord One thousand eight hundred and sixty-three.
