IMPROVEMENTS IN APPARATUS FOR MEASURING AND RECORDING THE FLOW OF LIQUIDS OR FLUIDS."
Year: 1872

page_text: LETTERS PATENT to Francis George Fleury, of 24, Merrick Square,
Southwark, in the County of Surrey, Engineer, and Alfred Tylor,
of No. 2, Newgate Street, in the City of London, Brassfounder, for
the Invention of "IMPROVEMENTS IN APPARATUS FOR MEASURING AND
RECORDING THE FLOW OF LIQUIDS OR FLUIDS."
PROVISIONAL SPECIFICATION left by the said Francis George Fleury
at the Office of the Commissioners of Patents, with their Petition,
on the 7th May 1872.
We, FRANCIS GEORGE FLEURY, of 24, Merrick Square, Southwark, in
the County of Surrey, Engineer, and ALFRED TYLOR, of No. 2, Newgate
Street, in the City of London, Brassfounder, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN APPARATUS FOR MEASURING
AND RECORDING THE FLOW OF LIQUIDS OR FLUIDS," to be as follows:-
This Invention refers to the class of inferential meters in which the
liquid to be measured in passing through the apparatus acts against
suitable tangential surfaces, thereby giving rotatory motion to a shaft or

page_text: spindle whose rotations are recorded by suitable mechanism, so as to
indicate the quantity of liquid or fluid passed through the apparatus.
Our Invention relates to constructing the apparatus in such manner
as to cause the pressure and velocity of the liquid or fluid passing
through the apparatus to regulate the areas through which the liquid or
fluid passes, in proportion to that pressure and velocity, at the same time
that it records the quantity passed. In the body of the apparatus a
division is formed with an opening through which the liquid passes, and
in this opening we place the valve or moving portion in which the
tangential openings are formed, through which the liquid or fluid passes.
This moving portion is so arranged by means of a suitably guided
spindle, or spindles and bearings, or equivalent means, that the pressure
of the liquid or fluid passing through the apparatus will cause this
moveable portion to rise according to the pressure and velocity of the
current, and so increase or diminish the area of the passage in the like 1
proportion, motion being given to the moving portion by the current
acting on the tangential parts formed on or attached thereto.
In that part of the apparatus which is below the moving portion we
place one or more suitably formed projections to prevent the entering
current of liquid or fluid attaining a rotatory motion and thereby pre-
venting the proper working of the apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis George Fleury in the Great Seal Patent
Office on the 7th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FRANCIS 25
GEORGE FLEURY, of 24, Merrick Square, Southwark, in the County of
Surrey, Engineer, and ALFRED TYLOR, of No. 2, Newgate Street, in the
City of London, Brassfounder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of May, in the year of 30
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Francis George Fleury and Alfred
Tylor, Her special license that we, the said Francis George Fleury

page_text: and Alfred Tylor, our executors, administrators, and assigns, or such
others as we, the said Francis George Fleury and Alfred Tylor, our
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 "In-
PROVEMENTS IN APPARATUS FOR MEASURING AND RECORDING THE FLOW OF LIQUIDS
OR FLUIDS," upon the condition (amongst others) that we, the said
Francis George Fleury and Alfred Tylor, our executors or administrators,
by an instrument in writing under our hands and seals, or under the
hand and seal of one of us or them, 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 we, the said Francis George Fleury and Alfred
Tylor, do hereby declare the nature of the said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, and the
Drawings therein referred to:-
This Invention refers to the class of inferential meters in which the
liquid to be measured in passing through the apparatus acts against
suitable tangential surfaces, thereby giving rotatory motion to a shaft or
spindle whose rotations are recorded by suitable mechanism so as to
indicate the quantity of liquid or fluid passed through the apparatus.
Our Invention relates to constructing the apparatus in such manner
as to cause the pressure and velocity of the liquid or fluid passing
through the apparatus to regulate the areas through which the liquid or
fluid passes in proportion to that pressure and velocity at the same time
that it records the quantity passed. In the body of the apparatus a
division is formed with an opening through which the liquid passes, and
in this opening we place the valve or moving portion in which the
tangential openings are formed, through which the liquid or fluid passes.
This moving portion is so arranged, by means of a suitably guided
spindle, or spindles and bearings, or equivalent means, that the pressure
of the liquid or fluid passing through the apparatus will cause this

page_text: moveable portion to rise according to the pressure and velocity of the
current, and so increase or diminish the area of the passage in the like
proportion, motion being given to the moving portion by the current
acting on the tangential parts formed on or attached thereto.
In the accompanying Sheet of Drawings Fig. 1 represents a central 5
longitudinal vertical section of our improved apparatus; Fig. 2 is a
vertical section at right angles to the foregoing; Fig. 3 is a horizontal
section of the apparatus shewing the parts below the line A, B, of
Fig. 1; Fig. 4 is a similar section shewing the parts below the line C, D,
of Fig. 1; Fig. 5 is a plan section of the valve or moving portion of the 1
apparatus; and Fig. 6 is a side elevation of the same.
a is the body of the apparatus; a¹ being the inlet and a³ the outlet.
The body a is formed with a division 6, having an opening for the
passage of liquid which is provided at its upper part with a valve seat c,
and contains the valve or moving portion d in which tangential 1
openings e are formed through which the liquid or fluid passes.
Attached to the valve d is a spindle ƒ which works in a bearing below
at g, and the upper part of the spindle is guided by a boss on the lower
portion of the clockwork or recorder box k. To the upper part of the
spindle is attached a worm 1 which gears into and drives the first 2
wheelm of the recording mechanism, which may be of ordinary con-
struction, the object being to record the revolutions of the spindle f.
In order to regulate the apparatus to work correctly the top of the
spindle works when at its full height against a boss o, which projects
from the bottom of the dial plate n, and when regulating the apparatus 2
if the valve d be found to run slowly, this projection or boss o must be
lengthened so as to give the valve d less rise, which will have the effect
of increasing the rapidity of the flow of liquid through the tangential
openings e and thereby increasing the number of revolutions of the
valve. On the top of the valve d are four projections or blades p.
3
The operation of the apparatus is as follows:-The liquid or fluid
enters the body a through the inlet a¹ and passes up within the valve d,
thereby raising it, until the liquid or fluid by passing out through the
tangential openings e causes the valve to rotate with its spindle ƒ,
which through the worm and wheel actuates the recording mechanism a
in the usual way, and the liquid or fluid leaves the apparatus by the
outlet a².

page_text: The action of the liquid or fluid upon the projections or blades p
prevents the over running of the valve.
Having described our said Invention of "Improvements in Apparatus
for Measuring and Recording the Flow of Liquids or Fluids," and having
explained the manner of carrying the same into practical effect, we
hereby declare that we do not claim as of our Invention or the exclusive
use of the several parts herein-before described or referred to, except
when the same are used in connection with a vertically moving rotating
portion or valve formed with tangential openings, as and for the purposes
specified, but what we consider to be novel and original and therefore
´claim as the Invention secured to us by the herein-before in part recited
Letters Patent is, the construction of apparatus for measuring and
recording the flow of liquids or fluids, substantially as shewn in and
described with reference to the accompanying Drawings.
In witness whereof, we, the said Francis George Fleury and Alfred
Tylor, have hereunto set our hands and seals, this Seventh day
of November, in the year of our Lord One thousand eight,
hundred and seventy-two.
