Improvements in Wet Gas Meters.
GEORGE MILLS 327 Milkwood Road Herne Hill, London S.E., Gas Engineer
do hereby declare the nature of this invention to be as follows:-
The improvement consists of the Measuring Wheel or Drum being divided into
cycloidal or crescent shaped compartments revolving on a fixed hollow shaft attached
to this shaft and in centre of Wheel or Drum is a hollow branch or pipe forming an
inverted Tee thus 1 the top of this branch is a seating for a valve on the branch
is a float or hollow cylinder which is allowed to slide up and down the perpendicular
part of branch, to this float is attached a conical shaped valve which rises and falls
with the float and water in the Meter.

Improvements in Wet Gas Meters.
GEORGE MILLS, 327 Milkwood Road, Herne Hill, S.E., Gas 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 :-
The Improvements consists of the Measuring Wheel or drum being divided into
cycloidal or crescent shaped compartments (A,) with a space in the centre (b) the ends
of all being covered, the whole revolving on its axis, or on a fixed shaft (c,) which
may be made hollow, with a branch pointing upwards and forming an inverted tee,
the top of this hollow, branch is a seating for a valve, a float or cylinder is allowed to
slide up and down the perpendicular part of the branch (d,) to this float or cylinder is
attached a cone or cover to fit the valve seating on the top of the branch, the float or
cylinder is made to rise or fall according to the height of the water in the meter, and
thus admit or shut off the gas in the centre of wheel or drum.
If a solid shaft is used the gas enters into the centre of wheel or drum in the usual
manner viz. through a bent pipe or tube, but if the hollow shaft is used, then, the
gas passes through it into the central space (b,) and from thence into the open end of
the cycloidal or crescent shaped compartment (A,) above the water line, and discharges
itself (after measurement) through the opening in the outer circle.
To compensate for the variation in the measurement of the gas through the lowering
of the water line in the meter 1 attach a tube (E) into each chamber of the drum
across the central space and so arranged that when these tubes are in a horizontal
position the tops are level with the highest water line in the meter the other end of
each tube is bent and inserted into the entrance of the opposite or filling chamber and
so arranged that as the water line in the meter is lowered each tube (E) will take a
proportionate quantity of the gas that has already passed the measuring chamber (A),
and return it into the opposite chamber that is then filling, and thus compensate for
the loss of registration occasioned by the lowering of the water line in the meter.
Having now particularly described and ascertained the nature of my Inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. The cycloidal or crescent shaped compartments.
2. The measuring drum or wheel being made to revolve on a fixed shaft either

into the interior of the measuring wheel or drum through a
4. The float and valve being fitted inside the measuring wheel or drum.
5. The mode of compensating, viz.-by taking a proportion of the measured gas
nd massing it through tubes into the chamber in course of filling.
