I, ARNOLD BUDENBERG, of the City of Manchester, Engineer, do
hereby declare the nature of the said Invention of "IMPROVEMENTS IN
METERS FOR MEASURING THE FLOW OF LIQUIDS," a communication to me
from abroad by Bernhard August Schäffer and Christian Frederick
Budenberg, of Buckau, Magdeberg, in the Empire of Germany, to be
as follows :—

the bottom of the outer casing, and at its upper annular edge forms
a valve seating, as herein-after described.
A vertical spindle mounted in the centre of the cylindrical partition
carries an inverted cylinder provided with a flange or annular projection
which overhangs the valve seating herein-before mentioned, and so acts
as a valve for closing the communication between the interior of the
cylindrical partition and the space surrounding it, and upon the outside

curved plates or vanes are constructed. ·
The liquid to be measured enters the interior of the cylindrical
partition through an inlet pipe which directs such liquid at a suitable
angle against the curved plates or vanes, and so causes the spindle
to revolve, whilst the pressure of the liquid at the same time lifts the
annular valve off its seating, and thus affords an exit for such liquid
into the space surrounding the cylindrical partition, from whence it is
finally conveyed to its destination by an outlet pipe. The upper end of
the spindle passes through a bearing into a dial case wherein it is geared
to counting mechanism.
It is preferred to fill this dial case (which forms a water-tight cover
to the outer casing) with glycerine or petroleum in order to prevent
the corrosion of the mechanism. It will thus be apparent that the
inverted cylinder acts as a water wheel which is caused to revolve
in direct proportion to the velocity of the liquid passing through
the meter, the number of revolutions being indicated by the counting
mechanism.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Arnold Budenberg in the Great Seal Patent Office
on the 14th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARNOLD
BUDENBERG, of the City of Manchester, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty.

page_text: seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Arnold Budenberg, Her special licence,
that I, the said Arnold Budenberg, my executors, administrators, and
assigns, or such others as I, the said Arnold Budenberg, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
METERS FOR MEASURING THE FLOW OF LIQUIDS," a communication to me
from abroad by Bernhard August Schäffer and Christian Frederick
Budenberg, of Buckau, Magdeberg, in the Empire of Germany, upon
the condition (amongst others) that I, the said Arnold Budenberg,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Arnold Budenberg, do hereby declaro
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement :-
A meter constructed according to this Invention consists by
preference of a cast metal outer casing internally divided by a cylin-
drical partition which rises vertically from and is in one piece with
the bottom of the outer casing, and at its upper annular edge forms
a valve seating, as herein-after described.
A vertical spindle mounted in the centre of the cylindrical partition
carries an inverted cylinder provided with a flange or annular projection
which overhangs the valve seating herein-before mentioned, and so acts
as a valve for closing the communication between the interior of the
cylindrical partition and the space surrounding it, and upon the outside
of the inverted cylinder, but below the flanged projection a series of
curved plates or vanes are constructed.
The liquid to be measured enters the interior of the cylindrical
partition through an inlet pipe which directs such liquid at a suitable.

page_text: angle against the curved plates or vanes, and so causes the spindle
to revolve, whilst the pressure of the liquid at the same time lifts the
annular valve off its seating, and thus affords an exit for such liquid
into the space surrounding the cylindrical partition, from whence it is
finally conveyed to its destination by an outlet pipe. The upper end of
the spindle passes through a bearing into a dial case wherein it is geared
to countino mechanism
angle against the curved plates or vanes, and so causes the spindle
to revolve, whilst the pressure of the liquid at the same time lifts the
annular valve off its seating, and thus affords an exit for such liquid
into the space surrounding the cylindrical partition, from whence it is
finally conveyed to its destination by an outlet pipe. The upper end of
the spindle passes through a bearing into a dial case wherein it is geared
to counting mechanism
It is preferred to fill this dial case (which forms a water-tight cover
to the outer casing) with glycerine or petroleum in order to prevent the
corrosion of the mechanism. It will thus be apparent that the inverted
cylinder acts as a water wheel which is caused to revolve in direct
proportion to the velocity of the liquid passing through the meter, the
number of revolutions being indicated by the counting mechanism.
In order that this my said Invention may be the more thoroughly
understood, and more readily carried into effect, I have hereunto annexed
a Sheet of Drawings illustrative of the same, similar letters being used to
denote similar parts on both of the views.
Fig. I. is a vertical section, and Fig. 2, a sectional plan of my.
improved liquid meter, in which A is the body of the meter formed
of cast metal, from the bottom B of which a cylindrical partition C
rises dividing the interior of the meter into an inner chamber D and
outer annular chamber E. The upper edge F of this cylindrical
partition forms a valve seating for the recepton of a valve herein-after
described. A passage G is constructed through the body A communi-
cating with the inner chamber D, entering such chamber at or about
the angle seen in the plan, Fig. 2, and forming the inlet port or passage
for the liquid to be measured. Another port or passage H is formed
through the body A communicating with the annular chamber E, and
this forms the outlet for the liquid; I is a vertical spindle supported
at its lower end in the bearing or footstep J, and at its upper end in a
bearing J¹ in the bottom of the dial case, K; L is a metallic flange or
valve secured upon the spindle I (by the collar b¹ and nut 6º), and
which flange or valve rests upon the valve seating F so constituting
a fluid-tight cover or valve to the inner chamber D. A cylinder M
carrying a series of vanes N is attached to and depends from the
valve L, the vanes N being set at the most suitable angle to receive

page_text: the impact of the incoming liquid entering by the port or passage G.
The valve L and cylinder M carrying the vanes N should be as light:
as possible, and may be constructed of vulcanite or thin metal. The
spindle. I is continued through the bearing J' into the interior of the
dial case K, within which it carries a long pinion Ọ gearing with
counting mechanism (the first wheel of which is seen at P), and such
counting mechanism is indicated by dials upon the upper face of the
cover plate K³. The dial case K is complete in itself, and rests upon
an annular ledge K³, and a strong glass plate Q held down by the
ring R which is screwed on to the body A, as illustrated, forms a
cover for the meter and dial case, and which cover is rendered water-
tight by a packing ring S of india-rubber or other suitable material
interposed between the glass Q and the cover plate K².
It is preferred to fill the interior of the dial case K and the space
beneath the glass plate Q with glycerine or petroleum to prevent the
corrosion of the counting and indicating mechanism.
The action of this liquid meter may be thus described :-When the
meter is at rest, that is, when no liquid is passing through it, the
valve L rests upon the valve seating F and forms a liquid-tight cover
to the inner chamber D, as herein-before described; but as soon as
the liquid commences to flow through the meter such valve L is lifted
off the valve seating F, and the entire weight of the cylinder and valve
is carried by or upon the escaping liquid; the friction, and consequently
the power necessary to turn such vane cylinder is thus reduced to a
minimum. At the same time the liquid coming against the vanes N
imparts rotary motion to the cylinder M and spindle I, varying according
to the quantity, and consequently velocity of the liquid passing through.
The height that the valve L is lifted above the valve seating F will
also vary according to the quantity of fluid passing by the valve, hence
the necessity of the long pinion O which actuates the counting mechanism
and so records the number of revolutions of the vane cylinder, and the
quantity of fluid passing through the meter.
Having thus particularly described and ascertained the nature of the
said Invention, I declare that I claim, the meter body A, internally
divided by the annular partition C, and filled with a flanged cylinder M
carrying vanes N when geared to counting mechanism contained in a

page_text: dial case K, which, together with the glass plate Q, forms a cover for the
meter, substantially as and for the purposes described.
In witness whereof, I, the said Arnold Budenberg, have hereunto
set my hand and seal, this Twelfth day of November, in the
year of our Lord One thousand eight hundred and seventy-
four.
