PROVISIONAL SPECIFICATION.
An Improved Liquid Measuring Appliance.
I CONRAD HERZOG of 37 Walbrook in the City of London Civil and
Mechanical Engineer, do hereby declare the nature of this invention to be ás
follows:-
My invention relates to an appliance for accurately measuring volumes of liquids
withdrawn from a supply vessel or reservoir which volumes may be definite in a
single appliance or adjustable to a desired variation of bulk in a single appliance.
My invention consists essentially of a dipping tube provided with an orifice at
either end and provided with an internal tube of smaller diameter passing through
the orifice at the top or at the bottom and adjustable in position therein for variable
volumes or fixed rigidly therein or as made part of the dipping tube for the definite
volumes the function of the said smaller tube being to determine the volume of
liquid received or retained by the dipping vessel.
To carry my invention into effect I may employ divers modifications of the said
dipping and regulating tubes of which the following are examples.
Where the regulating small tube is passed through the upper orifice of the
dipping tube and is adjustable, I provide a liquid tight stuffing box or joint in the
upper orifice and the inner regulating tube is pressed down to any desired point
within the dipping tube according to a scale externally marked upon the outer
tube.
The action is as follows:- When the dipping tube is passed into the liquid the
liquid rises driving out the air through the regulating tube until the liquid seals
the bottom of this tube. Should the liquid rise higher than this point it will only
compress the enclosed volume of air above it which by its elasticity will force back
the liquid to the bottom of the regulating tube as the dipping tube is raised from
the liquid. When the dipping tube is raised from the liquid the finger of the
operator or a valve is used to close the upper orifice of the tube to prevent the flow
of the measured liquid from the dipping tube until the finger is removed or the
valve opened.
Instead of the regulating inner tube being adjusted in the stuffing box the said
tube may be rigid and the lower part of the dipping tube may equivalently be
telescoped and adjustable as to length.
Where a definite volume only is required the regulating tube may be formed
with or attached to the lower definite chamber of the dipping tube so that a
definite chamber only is filled, the upper part of the dipping tube acting as a
protection only to the slight and easily breakable regulating tube.
As a small variable excess of liquid may exist in the regulating tube this is kept
of small diameter to minimise this quantity.
If this appliance is reversed & the regulating tube caused to pass out of the lower
orifice the appliance will act equally well as a liquid measurer.
The liquid will enter the dipping tube through the regulating tube and on
removal the former will retain only the liquid up to the level of the top of the
regulating tabe the upper orifice in this case remaining open during both dipping
and removal.
Where definite or slightly variable volumes only are required the lower part of
the dipping tube may be formed into a chamber communicating only with the upper
orifice by a small tube to reduce the area of liquid in contact with the air.
To discharge the liquid from this latter forin of measurer it is reversed in the
hand and the liquid poured from the upper orifice-the volume of chamber or tube

page_text: as compared with the length of regulating tube therein being so arranged that the
liquid cannot flow back through its admission tube.
If desired I may use stoppers tightly and rigidly fitting the mouths of the supply
vessels through which one or more dipping tubes of different capacities may be
inserted as easy sliding fits through suitable orifices.
If desired also the approximate depth to which the dipping tube may be inserted
into the supply vessel may be checked by an adjustable flange or ring of vulcanite
or other suitable material upon the outside of the dipping tube, coming down on
the said stopper which will also serve to exclude air when at rest.
My appliance may be conveniently constructed of glass or other suitable cleanly
and fluid resisting material.

COMPLETE SPECIFICATION.
An Improved Liquid Measuring Appliance.
I, CONRAD HERZOG, of 37 Walbrook, in the City of London, Civil and
Mechanical 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:―
My invention relates to an appliance for accurately measuring volumes of liquids
withdrawn from a supply vessel or reservoir which volumes may be definite in a
single appliance, or adjustable to a desired variation of bulk in a single appliance.
My invention consists essentially of a dipping tube provided with an orifice at
either end, and provided with an internal tube of smaller diameter, passing through
the orifice at the top or at the bottom, and adjustable in position therein for
variable volumes; or fixed rigidly therein; or made as part of the dipping tube
for definite volumes; the function of the said smaller tube being to determine the
volume of liquid received or retained by the dipping vessel.
To carry my invention into effect I may employ diverse modifications of the said
dipping and regulating tubes, of which the following are examples :-
Fig. 1 is a section of a vessel filled with spirits or liquid, and the dipping measure
resting therein, closing the mouth of the vessel as a cork.
Fig. 2 is a section of dipping or measuring tube, provided with gland and
adjustable regulating tube.
Fig. 3 is a section of dipping or measuring tube, with a telescopic adjustable
outer tube.
Fig. 4 is a reverse dipping or measuring tube with a regulating tube through the
bottom orifice.
Fig. 5 is a convenient arrangement of reservoir vessel, attached to a supply cask
cr vessel.
Where the regulating small tube A is passed through the upper orifice of the
dipping tube B and is adjustable, I provide a liquid-tight stuffing box or joint C
in the upper orifice, and the inner regulating tube A is pressed down to any desired
point within the dipping tube, according to a scale externally marked upon the
outer tube.
The action is as follows
:-
When the dipping tube is passed into the liquid, the liquid rises, driving out the
air through the regulating tube A, until the liquid scals the bottom of this tube.
Should the liquid rise higher than this point, it will only compress the enclosed
volume of air above it, which by its elasticity will force back the liquid to the
bottom of the regulating tube, as the dipping tube is raised from the liquid. When
the dipping tube is raised from the liquid, the finger of the operator or a valve is

page_text: used to close the upper orifice D of the tube A, to prevent the flow of the
measured liquid from the dipping tube until the finger is removed or the valve
opened.
Instead of the regulating inner tube A being adjustable in the stuffing box or
joint C, the said tube may be rigid with the outer tube as in Fig. 1, or the lower
part of the dipping tube B may equivalently be telescoped as at B and B¹ Fig. 3,
and adjustable as to length.
Where a definite volume only is required, the regulating tube may be formed
with or attached to the lower definite chamber of the dipping tube, so that a
definite chamber only is filled, the upper part of the dipping tube acting as a
protection only to the slight and easily breakable regulating tube.
As a small variable excess of liquid may exist in the regulating tube A, this is
kept of small diameter to minimise this quantity.
If this appliance is reversed and the regulating tube A caused to pass out of the
lower orifice of the dipping tube B, as in Fig. 4, the appliance will act equally well
as a liquid measurer..
The liquid will enter the dipping tube B (Fig. 4) through the regulating tube A,
and on removal the former, will retain only the liquid up to the level of the top of
the regulating tube A the upper orifice in this case remaining open during the
dipping and removal.
Where definite or slightly variable volumes only are required, the lower part of
the dipping tube may be formed into a chamber, communicating only with the
upper orifice by a small tube, to reduce the area of liquid in contact with the air.
To discharge the liquid from this latter form of measurer (Fig. 4) it is reversed
in the hand and the liquid poured from the upper orifice, the volume of chamber or
tube as compared with the length of regulating tube therein, being so arranged
that the liquid cannot flow back through its admission tube A.
If desired I may use stoppers tightly and rigidly fitting the mouth of the supply
vessels through which one or more dipping tubes of different capacities may be
inserted, as easy sliding fits, through suitable orifices.
If desired also the appoximate depth to which the dipping tube may be inserted
into the supply vessel may be checked by an adjustable flange E (Fig. 1), or a
ring of vulcanite or other suitable material upon the outside of the dipping
tube, coming down on the said stopper, which will also serve to exclude air when
at rest.
My appliance may be conveniently constructed of glass or other suitable cleanly,
and fluid-resisting material.
It may be convenient to construct the reservoir vessel F with a nipple or
union G, to which a pipe may be attached communicating with a supply cask H,
and controlled by a tap K, from which cask the supply of liquid to the reservoir
vessel F, may be maintained from time to time as required.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :--
1st. A liquid measuring appliance, consisting of a combination of an internal
regulating tube with an external dipping tube, the regulating tube being closed by
hand or by a valve, whilst the apparatus is being lifted from a liquid, into which it
has been dipped, so that a definite volume of liquid may be measured automatically
and independent of excess of immersion, and lifted by the dipping apparatus from a
vessel or reservoir, and afterwards discharged into a glass or vessel by the opening
of the regulating tube, substantially as described.
2nd. An external tube with an orifice at its lower end, provided with an internal
open tube of smaller diameter, fused, attached, or fixed so as to slide in a stuffing
box, in the upper end of the outer tube, and descending in the outer tube to a
certain distance, determining the level of liquid entering and remaining in the outer
measuring tube, substantially as described.

page_text: 3rd. An external tube with an orifice at its upper end provided with an internal
open tube of smaller diameter, fused, attached, or fixed so as to slide in a stuffing
box, in the lower orifice of the outer tube, and rising in the outer tube to a certain
height determining the level of liquid which can be retained by the outer measuring
tube substantially as described.
4th. in such a dipping tube measure a stuffing box or water tight joint, between
the inner tube and the outer tube, to admit of the adjustment of the inner
regulating tube with respect to the outer dipping tube, substantially as described.
5th. In such a dipping tube measure the formation of the lower ends of either
the inner or outer tubes in telescopic joints, so as to admit their relative adjustment
one to another as desired, substantially as described.
