Year: 1864

page_text: LETTERS PATENT to John Fulleck Hearsey, of Park Place, Church Street,
Brompton, in the County of Middlesex, Gentleman, for the Invention of
"IMPROVED APPARATUS FOR MEASURING LIQUIDS."-A communication from
PROVISIONAL SPECIFICATION left by the said John Fulleck Hearsey at
the Office of the Commissioners of Patents, with his Petition, on the
80th July 1864.
I, JOHN FULLECK HEARSEY, of Park Place, Church. Street, Brompton, in
the County of Middlesex, Gentleman, do hereby declare the nature of the
said Invention for "IMPROVED APPARATUS, FOR MEASURING LIQUIDS," to be as
follows:-
This Invention relates to a novel construction of apparatus in connection"
with an indicator for determining the quantity by weight of spirit or other
liquid that may be passed through it. The apparatus is provided with two
measuring vessels, which work on a centre with a fixed weight or lever so
placed that when it falls over the line of gravitation to any required degree it
causes the elevation of one of the two vessels and the depression of the other,.
and the simultaneous opening of a valve in a supply vessel above to allow of
the flow of the spirit or other liquid through it into the vessel so elevated.
When this vessel is filled to the required weight it falls over and strikes an
adjustable cushion provided to receive it. The vessel in its descent opens a
valve at the bottom of the vessel and discharges the spirit or other liquid into
a receiver below. As the two measuring vessels work on a common fixed
T:

page_text: centre their alternate action ensures the filling of the one while the other is
discharging its contents into the receiver, the motion being regulated by the
flow of the spirit or other liquid passing into and through them. The adjust-
ment of the cushions against which the falling vessels strike is for the purpose
of regulating the weight to the necessary leverage required in working the
instrument, for by reason of their, adjustment the vessels are capable of being
adjusted to the desired weight proportioned to the capacity of the vessels.
The cushions are fitted with springs so regulated that as soon as the weight,
on passing the centre, has acquired sufficient momentum to carry it down the
side of the descending vessel presses against a roller attached to the spring
and relieves it of its force on reaching the cushion; the rollers are fitted with
hinges and present no resistance on the ascent of the vessel. The indicator.
or counting apparatus is worked by the rocking action of the vessels in the
ordinary way, and it is so regulated as to indicate one degree on the dial for
each discharge of the contents of either vessel, and represents the weight to
which the instrument is adjusted by means of the regulating cushions. Ten
pounds is a convenient weight, as it represents the standard weight of an
imperial gallon of distilled water, by which the specific gravity of spirit is
regulated. The indicator is graduated on two dials, one representing units
and the other thousands. When spirits are to be measured, the tail of the
worms of the still passes into the supply cistern containing the supply valves
before mentioned. This cistern is fitted with a vessel termed a sampler, con-
nected with small reservoirs for receiving therefrom samples of the spirit.
The accumulated spirit in the cistern flows into the sampler through an open
valve at top, and thence, on the raising of a valve in the bottom thereof
through the action of a roller carried by the vibrating weight or lever before
mentioned which operates a valve lifter, is discharged in small or sample
quantities into the receiver at every pulsation of the measuring vessels. The
bulk of the spirit flows, as already indicated, into the oscillating measuring.
vessels, and quantity is registered by the indicating apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed:
by the said John Fulleck Hearsey in the Great Seal Patent Office on.
the 30th January 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
FOLLECK HEARSEY, of Park Place, Church Street, Brompton, in the County
of Middlesex, Gentleman, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of July, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Fulleck Hearsey, Her special license that I, the said John Fulleck
Hearsey, my executors, administrators, and assigns, or such others as I, the
said John Fulleck Hearsey, 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 "IMPROVED APPARATUS FOR MEASURING LIQUIDS," being a communication to
him from Edward Payne, of Montreal, Canada, upon the condition (amongst
others) that I, the said John Fulleck Hearsey, by an instrument in writing
under my hand and seal, 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 John Fulleck Hearsey, 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, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):-
This Invention relates to a novel construction of apparatus in connection
with an indicator for determining the quantity by weight of spirit or other
liquid passed through it. The apparatus is provided with two measuring
vessels, which work on a common centre with a weight or lever so placed
between them that when it falls over the line of gravitation to any required
degree it causes the rapid elevation of one of the vessels and the depression
of the other, and the simultaneous opening of a valve in a supply vessel above
to allow of the flow of the spirit or other liquid past it into the vessel so
elevated. When this vessel is filled to the required determinate amount it
falls over and strikes an adjustable cushion provided to receive it. The vessel
by its descent opens a valve fitted to the bottom of the vessel and thereby
discharges the spirit or other liquid into a receiver below.
As the two mea-
suring vessels work on a common fixed. centre their alternate action ensures
the filling of the one while the other is discharging its contents into the
receiver, the motion being regulated by the flow of the spirit or other liquid
passing into and through them. The cushions against which the falling vessels...

page_text: strike are made adjustable for the purpose of regulating the leverage required
in working the instrument, for by raising or lowering the cushions the fall of
the vessels is capable of being adjusted to their measuring capacity. The
cushions are fitted with springs so regulated that as soon as the weight, on
passing the centre, has acquired sufficient momentum to carry it down the
side of the descending vessel presses against a roller attached to the spring and
relieves it of its force on reaching the cushion; the rollers are fitted with
hinges and present no resistance on the ascent of the vessel. The indicator
or counting apparatus is worked by the rocking action of the vessels in any
ordinary way, and it is so regulated as to indicate one degree on the dial for
each discharge of the contents of either vessel, and represents the weight' to
which the instrument is adjusted by means of the regulating cushions. Ten
pounds is a convenient weight, as it represents the standard weight of an
imperial gallon of distilled water, by which the specific gravity of spirit is
regulated. The indicator is graduated on two dials, one representing units
and the other thousands, and by the addition of another dial one million
measures would be recorded.
In the accompanying Drawings, Fig. 1 shews in front view the improved
apparatus complete; Fig. 2 is a vertical section of the measuring apparatus
detached; Fig. 3 is a side view of one of the vessels into which the spirit
flows to be measured; and Fig. 4 is an end elevation of the pair of measuring
vessels.
A, A, is the outer casing of the apparatus, containing the vessel C, for sup-
plying the measuring vessels a, a, and the sampler D. The measuring vessels
a, a, are affixed to a rocking frame b, which is carried by a rock shaft b¹, having
its bearings in standards 62. Between the vessels a, a, is situated a lever or
weight 63, which, when thrown out of the perpendicular by the accumulation
of liquid in one or other of the vessels a, a, will facilitate the throwing over
or rocking of the vessels from side to side. To sustain the vessels in their
inclined position adjustable cushions c, c, are provided, the same being fur-
nished with regulating screws d, by which the weight or power of the leverage
of the rocking vessels is regulated. The supports of these cushions are screwed
firmly to the bed plate of the standards 62, which carry the rock shaft b', on
which the vessels are mounted. When measuring spirits, the tail of the
worm of the still guides the spirit in process of distillation into the trough B,
which is mounted in the supply cistern C, and form the upper part of the
instrument which I term the sampler. This sampler D is shewn on an
enlarged scale at Figs. 5, 6, 7, and 8, and it is connected with small reser-
voirs S, S, (Fig. 1) for receiving therefrom a sample of spirits passed through

page_text: the apparatus at every pulsation of the measuring vessels. The spirit, as it
accumulates in the trough B, overflows the trough and descends into the
cistern C, whence it passes past one or other of the valves e, e, fitted to the
bottom of the cistern C.immediately above the measuring vessels a, and enters
the vessel below..
1
I will now describe the arrangement for operating these valves e-f; f,
Fig. 2, are two small levers jointed at one end to brackets pendent from the
under side of the vessel C, and connected at their other end to the stems of
the valves e. These levers are actuated by a roller g, mounted on the top of
the weight or levere and pressing on the under face of the levers during the
rocking action of the vessels a, a, and lifting them together with their valves.
The vessels a are made of copper or other metal, and are fitted at bottom with
discharge valves a¹; a¹, each of which should be one-half larger area than the
valves e, e, of the cistern C, by which the spirit is admitted to the vessels a.
The stems of the valves a¹, a¹, project through the short tubes attached to the
bottom of the vessels, and as these vessels rock over to one or other side the
stems are severally brought into contact with one of a pair of short-pillars or
lifters h, h, which are fastened to the bottom of a tray or pan r, and thus the
valve is opened. and retained open until the liquid. is discharged into the pan r
through the short tubes before mentioned. The liquid then passes away to the
receiver by the pipe u Mounted on the rocking frame b is a bowle roller i,
which at each oscillation passes under and raises an antifriction roller k, mounted
at the lower end of a rectangular frame forming a portion of the sampler D.
The details of this sampler will be seen by referring to Figs. 5, 6, 7, and 8,
Fig. 5 being a front view thereof on an enlarged scale, Fig. 6 a vertical
section, Fig. 7 a side elevation, and Fig. 8 a sectional elevation with the
moving parts shewn in their highest position. is the moveable rectangular
frame, to which is pivotted a cup m by lateral pins m', by which it is raised
and lowered, it being guided by an outer and surrounding tubular vessel m³.
In the sides of this vessel m² slots are cut to receive the pins m¹ (see Fig. 7).
The cup m is fitted with a cross bar carrying a socket; this socket serves as a
support guide for the stem of a valve m³, which closes the open end of the
vessel m². Fitted to the bottom of the cup m is a spherical valve m², which,
when raised, discharges the sample of spirit, but which in Fig. 8 is shewn as
closed. On the fall of the frame 1 (which occurs when it is released from the
upward pressure of the bowle of the rocking frame 6), the cup m is brought
to the position shewn at Fig. 6, when the spherical valve striking the bar n
of a cup n¹ contained in the lower part of the vessel m³ will be raised and the
sample of spirit will flow into the cup n'. A division plate n² is made in this

page_text: cup for the purpose of dividing the sample into two portions; the divisions
formed by this plate lead by pipes o to the receivers s, s, into which the
samples are discharged. It will now be understood that the valve m³ being
lifted from its seat at each oscillation of the measuring vessels, samples of the
spirit supplied to the apparatus are being continually received from the
trough B into the sampler, and passing thence are stored up in the receivers
8, s. These samples may be divided into two equal or unequal parts, according
to the respective size of the discharge openings in the cup n¹.
By referring to the Drawings it will be seen that provision is made for
receiving the blow of the falling vessel before it strikes the cushion, and that
any ordinary arrangement of index or counting apparatus may be set in
action by the rock shaft for indicating the number of oscillations made, and
consequently the amount of liquid discharged by the measuring apparatus.
Having now set forth the nature of the Invention of improved apparatus
for measuring liquids, as communicated to me from abroad, and explained
the manner of carrying the same into effect, I wish it to be understood that
under the above in part recited Letters Patent I claim the measuring
apparatus constructed and operating as above described.
In witness whereof, I, the said John Fulleck Hearsey, have hereunto
set my hand and seal, the Thirtieth day of January, in the year
.
of our Lord One thousand eight hundred and sixty-five.
