A New or Improved Meter for Liquids, Gases, and Steam.
We, EUGENIE EMPAIN and JEANNE GLIBERT trading as the Firm of Glibert
& Cie of No. 35 Avenue de la porte de Hal, Brussels in the Kingdom of Belgium,
Manufacturers, 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:-
This new
or improved meter contains the following parts: A casing A
(Figures 1 and 2) consisting of two parts connected together by the bolts B and
between which a strongly compressed india rubber pad forms a thoroughly water
tight joint.
-The upper part of the envelope or casing A is provided with a movable box con-
taining the wheel work or counting mechanism which may be of any suitable type,
while the lower part is furnished with two screw threaded water inlet and outlet
pipes respectively, the inlet pipe containing a wire gauze cap preventing any
matter contained in the water from entering the meter while the outlet pipe is
furnished with a small back pressure valve so as to prevent-water from entering.
Two auxiliary valves S S¹ one of which allows the water to run out while the other
serves for the introduction of water into the apparatus operate in unison, the
characteristic feature of their construction being that one valve seat is placed out-
side while the other is arranged inside. These two valves are actuated by the
toggles c and c¹ connected to weighted levers held in position and under
constant tension by the small springs and by two larger toggles C C held in
position by the large levers L L controlled by the springs X X. The bellows y
provided with a number of copper rings Z are fixed at their lower end to the main
seat of the valve gear and at their upper end to the cover or lid K which carries a
disc or catch M for actuating the wheel work after each double oscillation.
T
In the central part of the lid or cover K is arranged a hollow rod T carrying at
its lower extremity a stop E. Outside this rod is arranged a tubular stop piece V
provided with a nut O and used to regulate the apparatus.
The valves S S¹ shown in front view and in section in the accompanying draw-
ings, wherein the springs are shown in side elevation in the latter view, operate in
the following manner:
As the water enters the meter through the wire gauze cap p, it passes through
the valve S¹ and reaches the bellows between the wings of its guide and the seat.
Under the pressure of water these bellows expand and ascend until the stop E
rigidly fixed on the rod T comes in contact with the toggles C C. From this
moment and under the same pressure, the ascending motion continues until the
toggles are free from the stops a¹ a¹. They then come into contact with the
stops a a under the action of the springs X X¹ and thus bring the valves against
their upper seats, so that the water which entered the bellows through the valve S¹
runs now outside the latter, the seat of the valve S¹ being obstructed by the valve;
the water contained in the bellows passes out through the valve S, and as the latter
likewise followed an ascending motion it prevents the water entering outside the
bellows from running directly through the small valve s of the delivery pipe.
This operation of the valve is carried on by reason of the fact that one valve

page_text: i.e., the water inlet valve has its seats inside, whereas the water outlet valve has
its seats outside. The two parts are moved by the toggles so that they are opened
and closed simultaneously.
To allow the bellows to return to the normal position, that is to say when the
seat of the valve S is open outwardly and the seat of the valve S inwardly,
the water in the bellows runs directly outside through the valve S whereas the
water entering through the wire gauze cap P reaches the outside of
the bellows through the lower seat of the valve S¹. The water outside the bellows
is under pressure and expels that which is inside by compressing the latter.
The lid or cover K also carries a stop piece V which bears in turn against the
toggles C C and causes them to descend and return to their first position shown in
the drawings ready for the next stroke. The water thus passing through is
mathematically and invariably measured by the capacity of the bellows or by its
collapsability. It may be mentioned that a double beating of the bellows is
required to actuate the counter mechanism. The apparatus containing say one
gallon, each beating measures one half gallon.
The apparatus is regulated by the screws E and O of the rod T. When properly
set the meter will accurately register the passage of the liquid through the gaug-
ing apparatus.
After each double oscillation the catch M actuates the lever R which operates
the counting mechanism through any. suitable gear.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
-
1. In meters for liquids, gases and steam, the arrangement of two auxiliary
valves actuated by means of suitable valve gear, substantially as herein
described and shown.
2. In meters for liquids, gases and steam, the arrangement of the valve gear
whereby the auxiliary valves are held upon their seats during the reversal of such
gear, substantially as herein described and shown.
3. In meters for liquids, gases and steam the mode of intermittently operating
the valve gear by means of the stops or tappets E, V after such oscillation of the
bellows substantially as herein described and shown."
4. In meters for liquids, gases and steam operating counting mechanism by
means of a catch such as M carried by the operating bellows, substantially as
herein described and shown.
5. The new or improved meter for liquids, gases and steam arranged, con-
structed and operating substantially as herein described and shown.
