page_text: I HENRY HERBERT SPORTON of 10 Benyon Road Southgate Road London
in the county of Middlesex Engineer do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in sluice valves wherein an apparatus is
fixed which approximately measures the quantity of water passing through a
sluice valve in any given time.
I first remove the valve and spindle from the inside of the body of the sluice
valve, I then fix a pear shaped and horizontal tube with a slot or division on the
top side, this pear shaped vessel or tube is fixed between the faces of an ordinary
sluice valve having a larger outlet than inlet, In this pear shaped and horizontal
tube I fix central cross bars, and on these central cross bars, I fix two horizontal
rods, I attach a cup shaped valve to these horizontal bars which moves in
proportion to the quantity of water passing through the sluice valve in any given
time.
Attached to this sliding cup shaped valve is an apperatus called a lattice which
communicates through cross bars with a vertical rod, this rod passes through a
false stuffing box made to fit the ordinary stuffing box of the sluice valve I pack
this false stuffing box with a cup leather which enables the rod to work with
much more freedom then if packed with the ordinary packing, On the top of the
vertical spindle I fix a spring which actuates upon a pencil passing through the
vertical spindle, Fixed upon the top portion of the sluice valve is a drum or
cylinder of sufficient height to record the stroke of the cup shaped valve upon the
horizontal rods in the body of the sluice valve. From a standard bolted to the
body of the sluice valve I fix an ordinary clock with eight day movements this
clock is geared into a circular cog wheel upon the drum which revolves once in
24 hours Thereby showing a line or series of lines on a diagram similar to a
recording barometer gauge.
I have another arrangement by which the same object can be effected that is by
useing a wire connected to the cup shaped valve on the central bars in the body of
the sluice valve over a pulley, this wire is then passed through the false stuffing

page_text: box and over a wheel imparting motion to the pencil as described before, I also
have another way of working the pencil I fix a parallel horizontal tube perforated,
of the size of the inlet of the sluice valve, This tube only reaches to the vertical
centre line of the sluice valve and then continues to the face of the outlet in frame
only, in this parallel and horizontal perforated tube, I fix a cross bar or centre at
the inlet and outlet ends, I then fix a central bar and on this central bar I fix a
piston which slides along this central bar in proportion to the quantity of water
passing through the sluice valve in any given time, I attach the lattice to this
piston which records in a similar manner the quantity of water passing through
the sluice valve in any given time.
I may also use a cone shaped valve which works in a seat on the inlet of the
sluice valve, to the back of this cone shaped valve I attach the lattice before
mentioned, by which motion is given to the vertical spindle which works the
pencil as before described.

page_text: An Apparatus for Estimating the Flow through a Sluice Valve.
I, HENRY HERBERT SPORTON, of 10 Benyon Road Southgate Road London in
the county of Middlesex 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 relates to an improved apparatus for estimating the flow of
water or other liquids through a sluice valve in any given time.
I first obtain an ordinary sluice valve made with a larger outlet than inlet but
in other respects precisely similar to the ordinary valve, I then remove the valve
and spindle from the inside of the body of the sluice valve, In the place of this
valve I fix a pear shaped and horizontal tube with a slot or division on the top
side, This pear shaped vessel or tube is fixed between the faces of the sluice valve
before mentioned, In this pear shaped and horizontal tube I fix central cross bars,
and on these central cross bars I fix a horizontal rod, attached to this horizontal
rod is a cup shaped valve, which moves in proportion to the quantity of water
or other liquid passing through a sluice valve in any given time.
Attached to this sliding cup shaped valve is an apparatus called a lattice which
communicates through cross bars to a vertical rod, This rod passes through a false
stuffing box made to fit the ordinary stuffing box of the sluice valve.
I pack this false stuffing box with a cup leather which enables the rod to work
with much more freedom than if packed with the ordinary packing.
On the top of the vertical spindle I fix a cross head or pencil holder in which is
fixed a spring which actuates upon a pencil that marks the diagram, Fixed upon
the top portion of the sluice valve is a drum or cylinder of sufficient height to
record the stroke of the cup shaped valve upon the horizontal rod in the body of
the sluice valve.
From a bracket bolted to the body of the sluice valve I fix an ordinary clock
with eight day movements, this clock is geared into a circular cog wheel upon the
drum before mentioned this drum revolves once in 24 hours thereby showing a
line or series of lines upon the diagram similar to a recording barometer gauge.
I have another arrangement by which the same object can be effected, that is by
using a wire connected to the cup shaped valve upon the central bar in the body
of the sluice valve and over a pulley, this wire is then passed through the false
stuffing box and over a wheel imparting motion to the pencil as described before.
In order that these said improvements be clearly understood, I will describe
them in detail conjointly with the figures in the accompaning drawings repre-
senting my apparatus for estimating the flow through a sluice valve.
Figure 1 represents a vertical sectional elevation of my improved apparatus
fixed in the body of the sluice valve, with the valve closed and the lattice shut up.
Figure 2 represents also a vertical section showing the valve full open, and the
attice with its weight, rod, and pencil at its extended position.
Figure 3. represents an end elevation abowing the cross bar, cup shaped valve,
nd edge of lattice, in the body of the sluice valve, The top portion shows the
bracket supporting the clock and drum, on which is stretched the diagram.

page_text: In these figures A represents the pear shaped and horizontal tube fitted between
the faces of the sluice valve B. C represents the cup shaped valve which slides
along the horizontal bar in the body of the sluice valve, D, is the lattice which
is attached to the cup shaped valve, E is the double slide bars also attached to
the lattice, F. is a lead weight upon the vertical rod G, H, is a small cross head
or pencil holder having a small spring to press lightly against the diagram. K, is
an ordinary eight day clock fixed upon the bracket L, this bracket is bolted to
the sluice valve the bracket L also supports the drum M on which is stretched
the diagram.
The working of the apparatus is as follows. A, is the pear shaped and horizontal
tube through which the water flows, opening the cup shaped valve C. by the
pressure of the incoming water, Thus when the speed of the outgoing water
increases, the valve gradually opens, expanding the lattice and thus transmitting
its horizontal motion to that of a vertical motion, it therefore communicates its
vertical motion to the vertical rod and pencil which marks the diagram as the
drum is revolved by the clock.
The same letters of reference apply to the same parts in each figure.
Having now described my invention and the best mode known to me of carry-
ing it into effect, I wish it to be clearly understood that I do not confine myself to
the precise details shown, as these may be varied indefinitely but what I desire to
claim is
1st The pear shaped and horizontal tube.
2nd The cup shaped valve.
3rd The lattice bars which communicate motion to the vertical rod and pencil.
4th The false stuffing box.
5th The general construction, combination and arrangement of an apparatus for
estimating the flow of liquids through a sluice valve in any given time substantially
as herein before described and illustrated in the accompanying drawings.
Dated this 17th day of May 1886.
