Improvements in or connected with Apparatus for Measuring the
Flow of Fluids through Pipes.
We, PALATINE ENGINEERING COMPANY LIMITED of 10 Blackstock Street,
Liverpool, in the County of Lancaster, and RALPH BLAKISTON of 10 Blackstock
Street, Liverpool, aforesaid, Engineer, do hereby declare the nature of this
invention to be as follows:-
.
This invention has reference to recording meters which record and indicate by
a diagram marked upon a chart, the rate of flow of liquid through said meter for
each instant of time. For instance, it has reference to meters known as the
"Deacon" meter, and other analogous or equivalent instrument. The object.
mainly of the present invention is to provide a means of enabling differential time
diagrams to be employed on the instrument.
In apparatus of the kind referred to employing a chart, on which a diagram is
drawn, and a time keeping motor by which this chart is moved, the parts are so
arranged and constructed, according to this invention, that the chart carrier is
adapted to make one complete movement, as a revolution of a drum carrying thei
chart either once in 24 hours, or once in seven days, at will. Of course, the
24-hour chart is marked to suit, its rate of movement and time of operation, and
the seven day chart is marked to suit such a duration, for its complete operation
and movement.
In a meter having this characteristic, with a drum for carrying the diagram
chart, and a clock for moving it, there is interposed between the clock and the
drum tooth gearing consisting of wheels, one having seven times the diameter of
the other, and a pawl or clutch, by which the one or other of these gearings can
be used. That is, the clock is adapted to revolve the diagram drum once in
24 hours, or once in 7 days; and this pawl, or connecting device, is so adapted,
that movement is transmitted from the clock to the drum through one or other of
these gearings, by operating the pawl or clutch, and putting one or other gearing
in action. When the small pinion wheel is out of action, it can be moved about a
support carrying it.
In one form of apparatus according to this invention, the clock is adapted to
revolve a spindle once in every 24 hours, and this carries the pawl wheel, in
connection with which a pawl, connected with the drum or drum wheel shaft above,
is adapted to engage and disengage; and above this is the larger toothed wheel
having a friction clutch between it and the pawl, and above this wheel is the drum
wheel. Then to one side, is the small pinion gearing with the larger, and carried
upon the clock body, by a standard; and upon this standard it may be turned out
of engagement with the large wheel upon a joint.
By this means an inspector can make a night inspection in the usual way with a
diagram revolving once in 24 hours, and thereby obtain a large scale diagram; and
then on this inspection being completed he can put a 7 day diagram on the same
drum, and by simply moving the pawl, the clock will turn the drum once in seven
days and thus give a complete record of the week's working.

We, PALATINE ENGINEERING COMPANY LIMITED, of 10 Blackstock Street,
Liverpool, in the County of Lancaster, and RALPH BLAKISTON, of 10 Blackstock
Street, Liverpool, aforesaid, 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 :-
This invention has reference to recording meters, which record and indicate, by
a diagram marked upon a chart, the rate of flow of liquid through said meter for
each instant of time. For instance, it has reference to meters known as the
"Deacon" meter, and other analogous or equivalent instruments.
The object
mainly of the present invention is to provide a means of enabling differential time:
diagrams to be employed on the instrument.
In apparatus of the kind referred to, employing a chart, on which a diagram is
drawn, and a time keeping motor by which this chart is moved, the parts are so
arranged and constructed, according to this invention, that the chart carrier is.
adapted to make one complete movement, as a revolution of a drum carrying the
chart either once in 24 hours, or once in seven days, at will. Of course, the
24 hour chart is marked to suit its rate of movement and time of operation, and
the seven day chart is marked to suit such a duration, for its complete operation
and movement.

In a meter having this characteristic, with a drum for carrying the diagram
chart, and a clock for moving it, there is introduced between the clock and the
drum tooth gearing consisting of wheels, one having seven times the diameter of
the other, and a pawl or clutch, by which the one or other of these gearings can
be used. That is, the clock is adapted to revolve the diagram drum once in
24 hours, or once in 7 days; and this pawl, or connecting device, is so adapted.
that movement is transmitted from the clock to the drum through one or other of
these gearings, by operating the pawl or clutch, and putting one or other gearing
in action. When the small pinion wheel is out of action, it can be moved about a
support carrying it, or reversed.
In one form of apparatus according to this invention, the clock is adapted to
revolve a spindle once in every 24 hours, and this carries the pawl wheel, in;
connection with which a pawl, connected with the drum or drum wheel shaft.
above, is adapted to engage and disengage; and above this is the larger toothed
wheel having a friction clutch between it and the pawl, and above this wheel, is
the drum wheel. Then, to one side, is the small pinion gearing with the larger,
and carried upon the clock body, by a standard; and upon this standard it may
be turned out of engagement with the large wheel upon a joint, or reversed.
By this means, an inspector can make a night inspection in the usual way with a
diagram revolving once in 24 hours, and thereby obtain a large scale diagram; and
then, on this inspection being completed, he can put a 7 day diagram on the same
drum, and by simply moving the pawl, the clock will turn the drum once in seven
days, and thus give a complete record of the week's working.
The drawings hereto annexed, illustrative of the invention, shew an apparatus
in which the diagram or chart to be marked is mounted on a cylinder, which is
rotated by a clockwork motor..
Figure 1 is an elevation, partly in section, of the apparatus,
Figure 2 is a plan in soation at A A W1

page_text: Figure 3 is a plan shewing the gearing for driving the drum. And
Figure 4 is a plan shewing the pawl carrier for engaging and disengaging the
alternate driving mechanisms.
Referring now to the drawings, a designates generally the diagram cylinder,
and b the clockwork motor, which is of the spring driven type commonly employed
in the differentiating meters for graphically recording the variation of the flow of
water in pipes, such as are used in waste water meters of the "Deacon" type, and
of other analogous or equivalent types. Within the body c or case of the clock
the gearing is contained for driving the drum cylinder a, and is driven by a spring
within the case d in the ordinary way. This gearing drives the arbor e of the
motor. On the upper end of the arbor e, there is fixed a disc f having a gap f¹ in
its periphery; and on the neck g of the cylinder supporting wheel or disc h, the
pawl i is mounted. This pawl is adapted to fit in the gap f¹ of the disc and
engage with such disc; and the neck g fits loosely over and upon the end of the
arbor e and revolves thereon. The pawl i is carried upon the neck g. by a carrier i¹,
on the end of which it is mounted by a hinge pin ; and it is adapted to be moved
into and held in the position out of engagement with the disc f, as shewn in the
full lines; or, in the position shewn in dotted lines, when it is in engagement with f.
In either of these positions, to which it is moved, it is retained by a spring pressed
locking pawl or catchj, the end of which is wedge shape, as shewn, and engages
with corresponding notches in the back of the pawl boss.
Passing through the roof of the clockwork case c, and guided by a sleeve k¹,
there is the second arbor or spindle k, upon the upper end of which a reversible
toothed pinion is carried; while on the neck y of the cylinder a there is a large
toothed wheel m meshing with 1, the connection of m with the neck being a
frictional one, exerted by the spring n, which bears at its inner edge on the pawl
carrier, and on the wheel m at its outer ends, the wheel m itself being loose on
the neck g. The wheel is made to engage with, and is rotated by the shaft or
arbor & by a pin thereon, over which the wheel I fits, being slotted as indicated,
at either side, to slide over the pin.
In action, the wheel m being seven times the diameter of 1, it will take seven
revolutious of 7 to give one revolution of m and the drum cylinder a, and if the
arbor k be revolved once in 24 hours the cylinder a will be revolved once in
seven days, and so a diagram shewing a week's variation of flow will be recorded.
To drive the cylinder a and chart by the other gear, so that it makes one
revolution every 24 hours, the cylinder a is taken off and the pinion is taken
out of gear with the wheel m (it being taken off the shaft k, reversed, and again
placed on the shaft, its teeth then being out of gear with the wheel m), and the
pawl i is turned down into the position shewn in dotted lines, so that when the
cylinder is again put on the arbor, the pawl engages with the disc f; and when
so engaged, the cylinder a is revolved at the same rate as the arbor e, viz., once
in 24 hours, which is the usual way of working, in making a night inspection
for the detection of waste of water, in water service mains.
With regard to the form and arrangement of the parts shewn in the drawings,
it is to be stated the invention is not restricted to that particularly shewn, since.
it will be plain it may be varied in different ways without departing from the
general characteristic of the invention, and further, that in the application to
different types of recording meters or special cases, it will necessarily be modified
and adapted to suit them.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. A meter for recording the varying flow of liquids in pipes, having two
driving gears for moving the diagram carrier, and adapted to operate same at
different rates of speed, the said two gears being driven from a single clock
motor; substantially as described for the purposes specified.

page_text: 2. In a recording meter for recording the rate of flow of liquids through
pipes having a rotary cylinder carrying the diagram chart, and a clockwork
motor in connection with same, said motor and cylinder being provided with
separate driving parts adapted to be engaged and disengaged, and to drive the
cylinder at varying rates; substantially as set forth with reference to and shewn in
the drawings.
3. In a recording meter of the kind herein described and claimed, the construction
and arrangement of the alternate driving mechanisms and parts, particularly as
shewn in, and set forth with reference to the drawings.
