IMPROVEMENTS IN GAS METERS
Year: 1875

page_text: LETTERS PATENT to George Goldsmith, of Leicester, in the County of
Leicester, for the Invention of “IMPROVEMENTS IN GAS METERS.”
PROVISIONAL SPECIFICATION left by the said George Goldsmith at
the Office of the Commissioners of Patents, with his Petition, on
the 24th July 1875.
I, GEORGE GOLDSMITH, of Leicester, in the County of Leicester, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
GAS METERS," to be as follows:―
This Invention has for its object the improvement of wet gas meters
in several respects,―
Firstly. In providing means for indicating the height of water in an
) ordinary wet meter, or in the reservoir of a compensating or a fountai
meter. This is done by connecting to the float a rod or pointer which

page_text: passes through the upper part of the meter in front of the dial or index
plate, or other convenient place, and which rises and falls with the float.
To prevent leakage of gas or admission of air the rod or wire is passed
through a tube or pipe, the lower end of which is sealed by the water
in the meter or reservoir, as the case may be, and the upper end is open
to the index box or other convenient place.
Secondly. An improved method of connecting the valve to the float
by means of an arm or rod which passes through another pipe or tube,
which is sealed by the water at the lower end, and is open to the valve
box at the top or upper end The action is exceedingly simple, for
both the rods are so connected with the float that upon water being
admitted to the meter or reservoir the float rises, and with it the inlet
valve on the one side, and the rod or pointer on the other, thus showing
by the relative position of the top of the pointer to certain marks upon
the index plate or other convenient place what quantity of water is in
the meter or reservoir, and whether or not a fresh supply is needed;
or the rod or pointer may be connected to another and distinct float,
but for simplicity the previously described method is preferred.
Thirdly. In securing means for conveniently adjusting the water line
in fountain or other wet meters This is effected by fixing to the
partition between the front and the drum a small box open to the
drum chamber, and provided with a pipe which screws into the upper
part of the box just mentioned. The pipe is furnished with a square
opening at its upper end to admit of the entrance of a key by which
the pipe may be by turning raised or lowered until the proper adjust-
ment is produced.
Fourthly. In providing means for adjusting the height of the spout
in ordinary or other meters. This is done by connecting the inlet pipe
with a small box or chamber, and also connecting to this box or
chamber the spout by means of a screw cut upon it. Supposing the 3
spout as inserted to be so high or so low as to produce an incorrect
water line, then all that is necessary is to partially turn the spout
by degrees either to the right or left until its top is sufficiently depressed
or raised to produce the proper water line, when the spout may be fixed
by soldering or otherwise.

page_text: And, Fifthly. In furnishing the waste water box with a float and
valve, so that when waste water runs into the box the float riscs and
opens the valve and the water may be run off, but when the water
is run off the float falls and closes the valve so that no unregistered
gas can be obtained.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Goldsmith in the Great Seal Patent Office
on the 22nd January 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
GOLDSMITH, of Leicester, in the County of Leicester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of July, in the year
of our Lord One thousand cight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Goldsmith, Her special licence,
that 1, the said George Goldsmith, my executors, administrators, and
assigns, or such others as I, the said George Goldsmith, my 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
there 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 GAS METERS," upon the condition (amongst others) that I, the said
George Goldsmith, my executors or administrators, by an instrument in
Writing under my, or their, or one of their hands and seals, 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 Scal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.
. NOW KNOW YE, that I, the said George Goldsmith, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained

page_text: in and by the following statement, reference being had to the accom-
panying Drawings, and to the letters and figures marked thereon, that is
to say
This Invention has for its object the improvement of wet gas meters
in several respects,-
Firstly. In providing means for indicating the height of water in an
ordinary wet meter, or in the reservoir of a compensating or a fountain
meter. This is done by connecting to the float a rod or pointer which
passes through the upper part of the meter in front of the dial or index
plate, or other convenient place, and which rises and falls with the float.
To prevent leakage of gas or admission of air the rod or wire is passed
through a tube or pipe, the lower end of which is sealed by the water
in the meter or reservoir, as the case may be, and the upper end is open
to the index box or other convenient place.
Secondly. An improved method of connecting the valve to the float
by means of an arm or rod which passes through another pipe or tube,
which is scaled by the water at the lower end, and is open to the valve
box at the top or upper end. The action is exceedingly simple, for
both the rods are so connected to the float that upon water being
admitted to the meter or reservoir the float rises, and with it the inlet
valve on the one side, and the rod or pointer on the other, thus showing
by the relative position of the top of the pointer to certain marks upon
the index plate or other convenient place what quantity of water is in
the meter or reservoir, and whether or not a fresh supply is needed;
or the rod or pointer may be connected to another and distinct float,
but for simplicity the previously described method is preferred
Thirdly. In securing means for conveniently adjusting the water line
in fountain or other wet meters This is effected by fixing to the
partition between the front and the drum a small box open to the
drum chamber, and provided with a pipe which screws into the upper
part of the box just mentioned The pipe is furnished with a square
opening at its upper end to admit of the entrance of a key, by which
the pipe may be by turning raised or lowered until the proper adjust-
ment is produced.
Fourthly. In providing means for adjusting the height of the spout ¦

page_text: For the purpose of adjusting the water line in fountain meters
a tube P is provided, the lower part of which S is of smaller diameter
so as to enter through a stuffing box into the little box or chamber Q,
where the lower part of the small pipe is ordinarily sealed with the
liquid in the meter. In the upper part of this small box or chamber
Is a hole which communicates with the drum chamber When tho
lower part of the small tube becomes unsealed through loss of water
by evaporation or otherwise the gas from the drum chamber enters by
the hole before mentioned, and passes into the upper part of the front
chamber, when water will flow from the reservoir into the drum
chamber until the small tube is again scaled; R is a screw furnished
with a square head so as to be turned by a key inserted through the
bottom of the index box, and is used to adjust the small pipe S before
referred to, E is the waste water box provided with a hinged float U
and valve V, which opens or closes the way to the run-off or waste water
plug W.
Having now described and particularly set forth the nature of this
Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that I do not confine
or restrict myself to the precise details or arrangements which I have 2
described or referred to, as variations may be made therefrom without
deviating from the principles or main features of this Invention; but
what I consider to be novel and original and therefore claim as the
Invention secured to me by the herein-before in part recited Letters
Patent is,-
First. The arrangement for indicating the water level in fountain or
other meters, as described and shown on the Drawings
Second The arrangement for connecting the valve O to the float Y.

page_text: And, Fifth. The construction of the float U of the form shown, and
the arrangement for attaching it to the valve V, as described and shown
on the Drawings.
In witness whereof, I, the said George Goldsmith, have hercunto
set my hand and scal, this Twenty-first day of January, in the
year of our Lord One thousand eight hundred and seventy-
SIX.
GEORGE GOLDSMITH. (L.S.)
