PROVISIONAL SPECIFICATION.
An Improved Water Meter.
We, WALTER GEORGE KENT, Manufacturer, and HENRY SAMUEL PRICE,
Engineer, both of 199, 200 and 201 High Holborn, in the County of Middlesex, do
hereby declare the nature of this invention to be as follows:-
This invention has for its object an improved water meter. The improved water
meter as we prefer to construct it, consists of a pair of upright cylinders parallel the
one to the other, and cast in one piece. The cylinders are provided with pistons and
with ports at either end for the ingress and egress of the water to be measured. Each
piston rod passes out at the top of its cylinder by a gland, in which is a leather
packing. The gland is fitted into an aperture in the cylinder end, it is inserted
from within the cylinder, and is secured by a ring nut, screwed on to it on the outer
side. There is a head upon the piston rod, and a guide for this head is formed in
one piece with the gland.
In the upper face of the cylinder casting and between the cylinders, there is a
row of apertures which are the open ends or mouths of the various passages which
the cylinder casting contains. These apertures, naming them in the order in
which they occur, are in connection respectively with 1, the inlet 2, the bottom of
one of the cylinders 3, the top of this cylinder 4, the top of the other cylinder
5, the outlet.
Upon the top of the cylinder casting, and over these apertures, a block with
corresponding apertures on its underside is secured. On opposite sides of this block
also valve faces are formed parallel to the piston rods and upon each valve face
a D valve works. The valve has horns, and the head of the piston rod, as it comes
to the end of its stroke, strikes the horn of the valve and moves it. The piston
rod belonging to one cylinder, thus controls the valve, belonging to the other
cylinder. The valve face in each case has three ports, one in connection with the
under side of the piston, another with the upper side, and between the two. an
exhaust or egress port.
Within the block there are five chambers corresponding
to the ports in the valve faces, a chamber for each port except that the two exhaust
ports are in connection with the same chamber. The apertures in the underside of
the block connect with the several chambers, each to cach, and when the block is
in place, coincide with the apertures in the upper face of the cylinder casting. A
casing encloses the mechanism on the top of the cylinder casting; the interior space
is divided into two parts by a perforated partition which forms a strainer. The
inlet passage admits water to the compartiment on one side of the strainer and in
the compartment on the other side of the strainer, the valves work. The valves
allow the water to pass out from the compartment into the cylinders, sometimes on
the upper and sometimes on the lower side of the piston. The water returns from
the cylinders to the interior of the D valves, and thence it passes to the egress
ports and passages.
There is a counter on the top of the casing in a chamber of its own; it is worked
by a ratchet and pawl. The axis of the pawl lever passes by a stuffing box into
the casing containing the valves and other mechanism, and here it carries a pendant
arm. The arm is slotted longitudinally, and a bowl carried on the head of one of
the piston rods enters the slot. As the axis of the pendant arm is not in the line
along which the bowl travels, the lever receives a rocking movement, through an arc
sufficiently large to give the requisite travel to the pawl which drives the counter.

We, WALTER GEORGE KENT, Manufacturer, and HENRY SAMUEL PRICE,
Engineer, both of 199, 200 and 201 High Holborn, in the County of Middlesex, do
hereby declare the nature of this invention and in what manner the same is to he
performed to be particularly described and ascertained in and by the following
statement:―
This invention has for its object an improved water meter. The improved water
meter as we prefer to construct it, consists of a pair of upright cylinders parallel
the one to the other, and cast in one piece. The cylinders are provided with pistons
and with ports at either end for the ingress and egress of the water to be measured.
Each piston rod passes out at the top of its cylinder by a gland, in which is a leather
packing. The gland is fitted into an aperture in the cylinder end, it is inserted
from within the cylinder, and is secured by a ring nut, screwed on to it on the outer
side. There is a head upon the piston rod, and a guide for this head is formed in
one piece with the gland."
In the upper face of the cylinder casting and between the cylinders, there is a
row of apertures which are the open ends or mouths of the various passages which
the cylinder casting contains. These apertures, naming them in the order in
which they occur, are in connection respectively with 1 the inlet, 2 the bottom of
one of the cylinders, 3 the top of this cylinder, 4 the top of the other cylinder,
5 the outlet.
Upon the top of the cylinder casting, and over these apertures, a block with
corresponding apertures on its underside is secured. On opposite sides of this
block also valve faces are formed parallel to the piston rods and upon each valve
face a D valve works. The valve has horns, and the head of the piston rod, as it
comes to the end of its stroke, strikes the horn of the valve and inoves it. The
piston rod belonging to one cylinder, thus controls the valve, belonging to the other
cylinder. The valve face in each case has three ports, one in connection with the
underside of the piston, another with the upper side and between the two an exhaust
or egress port. Within the block there are five chambers corresponding to the
ports in the valve faces, a chamber for each port except that the two exhaust
ports are in connection with the same chamber. The apertures in the underside of
the block connect with the several chambers each to each and when the block is in
place, coincide with the apertures in the upper face of the cylinder casting. A

A. A are a pair of upright cylinders parallel the one to the other and cast in one
piece. The cylinders are provided with pistons B B and with ports C C, at either
end for the ingress and egress of the water to be measured. Each piston rod B¹
passes out at the top of its cylinder by a gland D in which is a leather packing E.
The gland is fitted into an aperture in the cylinder end, it is inserted from within
the cylinder and is secured by a ring nut D₁ screwed on to it from the outer side.
There is a head B upon the piston rod B¹ and a guide D" for this head is formed
in one piece with the gland.
In the upper face of the cylinder casting and between the cylinders there is a
row of apertures which are the open ends or mouths of the various passages which
the cylinder casting contains. Fis the inlet for the water. G is in connection
with the bottom of left hand cylinder, Figures 1 to 5. Gis in connection with the
top of the right hand cylinder. G' is in connection with the top of the left hand
cylinder. G is in connection with the bottom of the right hand cylinder, and H is
in connection with the outlet.
Upon the top of the cylinder casting and over these apertures there is a block J
with corresponding apertures on its underside, but the inlet F does not pass through
the block. This block is called the port block and is shown separately in Figures 7
to 10. The passages in it bear the same letters as the corresponding passages in
the cylinder casting of which they form continuations. On opposite sides of the
block J valve faces are formed parallel to the piston rods and upon cach valve face
a "D" valve K works. This block is cast of white metal the port faces being of
brass which is placed in the mould and held in position during casting. The valve
has horns K and the head of the piston rod as it comes to the ends of its stroke
strikes one or other of the horns and moves the valve. The piston rod belonging
to one cylinder thus controls the valve belonging to the other cylinder. The valve
face in each case has three ports one in connection with the underside of the piston,
another with the upper side and between the two an exhaust or egress port.
The mechanism on the top of the valve casting is enclosed in a casing L the
interior space being divided into two parts by a perforated partition L' which forms
a strainer. The inlet passage F admits water to the compartment on one side of
the strainer, and in the compartment on the other side of the strainer the valves
work. The valves allow the water to pass out from this compartment into the
cylinders sometimes on the upper and sometimes on the lower sides of the pistons.
The water returns from the cylinders to the interior of the "D" valve K and from
thence it passes to the outlet H.
On the top of the casing L is a chamber M containing a counter of any ordinary
construction and worked by a ratchet and pawl. This mechanism forms no part
of the invention and is not shown in detail in the drawings. The axis N of the
pawl lever passes by a stuffing box into the casing L and it carries a pendant
arm N slotted longitudinally to receive a bowl O carried on the head of one of
the piston rods. As the axis of the pendent arm is not in the line along which

page_text: the bowl travels the lever receives a rocking movement through an are sufficiently
large to give the requisite travel to the pawl which drives the counter.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
