Improvements in Water Meters and the like..
I, GUSTAVE DUBUISSON, of Chaussée d'Anvers No. 1, Brussels, Belgium,
Manufacturer, 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 object of my invention is to provide a water meter of extreme simplicity
in construction as well as of absolute regularity and accuracy in operation.
The accompanying drawing illustrates by way of example one form of con-
struction for this meter.
Figure 1 is a vertical section and Figure 2 is a plan of the same.
The apparatus consists of:-
1st. A framework consisting of two cylinders 1 and 2 in juxtaposition and of
absolutely identical dimensions (which may be called two twin cylinders) in
each of which is placed a cylindrical piston 3 and 4 respectively these pistons
are each furnished with a rod 5 and 6 respectively the use of which will be herein-
after described.
2nd. The pistons 3 and 4 as well as the rods 5 and 6 which are fixed to them,
are subjected to the lateral pressure of the hydraulic packing 7 for the pistons
and 8 for the rods.
The packing 7 of each piston is placed half way up the cylinder in an enlarge-
ment 9 which serves as a recess for it. There is provided behind the packing
a chamber 10 which is filled with water by the pipe 11 connected with the pipe 12
for the cylinder 1 and with the pipe 13 for the cylinder 20
The packing under the pressure of the water contacts closely upon the walls
of the piston.
The packing S of each piston rod is placed in a cap 14 which is bolted or screwed
on to the cylinder cover.
Behind the packing 8 is a space 15 into which the water contained in the
cylinder is introduced by the pipe 16.
The packing under the pressure of the water contacts closely upon the surfaces
of the rods 5 and 6.
3rd. Each of the two cylinders 1 and 2 is provided at its upper end with a
cock 17 and 18 respectively having plugs 19 and 20 respectively forming in the
body of the cock 17 two chambers 21 and 22, and in the body of the cock 18 two
chambers 23 and 24.
To each cock are fixed four small tubes and each plug is controlled by a lever;
the plug 19 by the lever 25 passing into a slot 27 made in the upper part of the
rod 6 of the piston 4, and the plug 20 by the lever 26 passing into a slot 28
made in the upper part of the stem 5 of the piston 3.
The apparatus operates in the following manner:-
The water from the reservoir arrives by the port 29 and passes through the
pipe 30 and the chamber 21 of the cock 17 and enters the cylinder 1 by the
pipe 31 and exerts a pressure on the upper surface of the piston 3. The latter,
driven by this pressure, drives out the water in the cylinder 1 under the lower
surface of the piston 3 from the cylinder 1 by the pipe 12.

page_text: This water passes through the chamber 22 of the cock 17 and flows away
through the pipe 32 to deliver for consumption, passing through the port 33.
The piston 3 in the position as shown in the drawing is at the end of its
stroke from top to bottom, and by means of its rod 5 in the slot of which the
lever 26 passes,
causes the plug 20 of the cock 18 to move from the position
indicated by the line C D to that indicated by the line C¹ D¹. The piston 3
remains inactive in this position and the water from the reservoir entering by
the port 29 flows by the pipe 34 into the chamber 23 of the cock 18, passes out
of this chamber by the pipe 13, enters by this pipe into the cylinder 2 under the
lower surface of the piston 4 and causing it to rise drives out the water from the
cylinder 2 which is above its upper surface. This water flows through the pipe 35
into the chamber 24 of the cock 16, to pass from this chamber by the pipe 36
to deliver for consumption through the port 33.
When the piston 4 has arrived at the end of its upward stroke, it causes, by
means of the lever 25 passing through the slot 27 in the rod 26, the plug 19 of
the cock 17 to pass from the position indicated by the line F G to that indicated
by the line FI GI, which allows the water from the reservoir to pass through
the pipe 30, the chamber 22 of the cock 17, and the pipe 12, and to act on the
lower surface of the piston 3 in the same way as it acted on the lower surface
of the piston 4 which is motionless, and the water in the cylinder 1 above the
upper surface of the piston 3 flows away by the pipe 31, the chamber 21 of the
cock 17 and the pipe 32 to be delivered for consumption by the port 33.
When the piston 3 has arrived at the end of its stroke from top to bottom
it causes, by means of the lever 26, the plug 20 of the cock 18 to return to its
former position indicated by the line CD and the water from the reservoir,
passing through the pipe 34, the chamber 24 of the cock 18, enters through the
pipe 35 into the cylinder 2 above the upper surface of the piston 4, which driven
by the pressure while the piston 3 is motionless, drives out through the pipe 15,
the water which is under its lower surface in the cylinder 2.
This water flows away through the chamber 23 of the cock 18, then through
the pipe 36 to be delivered for consumption through the port 33.
An action alternatively the same for each of the two pistons is thus obtained,
which by means of the up and down movement of their rods operates the counting
mechanism at the end of each stroke.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim
is:-
1st. In a piston water-supply meter the combination of distribution cocks
provided with rotary plugs with levers controlling said cocks actuated by the
piston rods, substantially as described.
2nd. In a piston water-supply meter as claimed in Claim 1 water-tight glands
for the pistons and piston rods consisting of packing of leather or other suitable
material submitted to the pressure of the water, substantially as described.
3rd. In a piston water supply meter the combination of parts, substantially
as described and illustrated in the accompanying drawings.
Dated this 10th day of August 1899.
