Improvements in Apparatus for Measuring Liquids.
1 JOHN WILLIAM HARTLEY of California Works, Stoke-on-Trent, in the county
of Stafford, Engineer, do hereby declare the nature of this invention to be as
follows:-
:―
This invention is intended more particularly for measuring small quantities of
liquid fuel for Petroleum Engines, but the invention is also applicable to measuring
liquids generally in small quantities, and the invention consists in the use of fine wire
gauze to dip into the liquid and hold the same by capilliary attraction, and from which
is removed by a blast of air directed by a blow pipe.
In carrying out my invention as applied to a Petroleum engine, I employ a casing
having a suitable lateral outlet opening in connection with the explosion chamber of
the engine. In this casing, I may mount a cylinder of fine wire gauze, which is
capable of being rotated, and also shifted in a longitudinal direction. This cylinder
dips into a vessel containing the liquid fuel, which it takes up as it rotates, and brings
it in front of the outlet.
The air to blow the liquid fuel from the gauze into the outlet opening is conveyed
to the inside of the cylinder by a pipe arranged with its discharge orifice opposite
the outlet in the casing, so that the liquid, when the blast acts, will be driven through
the outlet to the engine. The wire gauze will hold the liquid until it is blown away
by the blast. The object of mounting the cylinder so that it can be moved longi-
tudinally, is to bring more or less of the cylinder in front of the outlet, and within
the range of the air blast, by which means more or less liquid can be blown into the
engine as required.
The wire gauze may be in the form of a rotary disc, or it may be a reciprocating
disc, dipping into the liquid, and moving or working between the blast pipe and the
outlet in the casing:
By these means, I am enabled to measure liquids in minute quantities with great
accuracy, for various purposes, say, for example, measuring out doses of tinctures
used in homeopathy, a piece of gauze of the dimensions required being arranged in
front of the orifice of a small blow pipe.

Improvements in Apparatus for Measuring Liquids.
1 JOHN WILLIAM HARTLEY of California Works, Stoke-on-Trent in the County of
Stafford, 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 is intended more particularly for measuring small quantities of liquid
fuel for petroleum engines, but the invention is also applicable generally for measuring
liquids in small quantities, and the invention consists in the use of fine wire gauze to
dip into the liquid and hold the same by capillary attraction, and from which it is
removed by a current of air directed by a blow pipe, or produced by a vacuum.
In carrying out my invention, as applied to a petroleum engine, I employ a casing
having a suitable lateral outlet opening, and adapted to the explosion chamber of the
engine.
In this casing I mount a piece of fine wire gauze, say in the shape of a cylinder

page_text: which is capable of being rotated, and also shifted in a longitudinal direction. This
cylinder dips into a vessel containing the liquid fuel, which is taken up as the cylinder
rotates and is brought in front of the outlet.
Air to blow the liquid fuel from the gauze into the outlet opening is conveyed to
the inside of the cylinder by a pipe arranged with its discharge orifice opposite the
outlet in the casing, so that the liquid, when the blast acts, will be driven through the
outlet to the engine. The wire gauze will hold the liquid until it is blown away by
the blast. The object of mounting the cylinder so that it can be moved longitudinally,
is to bring more or less of the cylinder in front of the outlet, and within the range of
the air blast, by which means more or less liquid can be blown into the engine as
required.
The wire ganze may be in the form of a rotary disc, or it may be a reciprocating
disc, or an endless band dipping into the liquid and moving or working between the
blast pipe and the outlet in the casing.
By these means I am enabled to measure liquids in minute quantities with great
accuracy for various purposes, say, for example, for measuring out doses of tinctures
used in homeopathy, in which case a piece of gauze of the dimensions required,
carried by a wire, will be arranged in front of the orifice of a small blow pipe.
In the accompanying drawings,
Fig. 1 is a front elevation of the gauze cylinder arrangement, and
Fig. 2 is a transverse section taken at right angles to Fig. 1.
Fig. 3 is a sectional elevation, and Fig. 4 a transverse section, of a modification.
Fig. 5 is a plan view, which will practically serve for either arrangement. Fig. 6
is a front clovation, and Fig. 7 a transverse section, of a reciprocating gauze
arrangement. Figs. 8 and 9 show, in sectional elevation and plan, a gauze disc
arrangement, and Fig. 10 shows the adaptation of my invention to measuring out
homeopathic tinctures.
A is a reservoir or vessel, which will be attached to the piston cylinder of the
engine, and is intended to contain the liquid fuel, and A¹ is a cover which may
be secured in any convenient manner to the vessel A. In front of this vessel is
an opening B, which serves as the outlet for the liquid. The vessel will be placed so
that this outlet will coincide with the inlet to the piston cylinder. In the side of
the vessel is another opening C, which serves as an inlet for air, and in connection
with this opening is a curved pipe or nozzle (2, which has its exit orifice opposite
the outlet B (see Fig. 6). D, Figs. 1 and 2, is a cylinder of wire gauze, which is
secured to a pulley D'. This pulley is mounted upon a shaft E, which works in
a sleeve F, carried in a bearing F in the side of the vessel A. This sleeve F is
intended to have a longitudinal motion in its bearing, for which purpose its outer
end is provided with a grooved pulley F, and a shifting fork F³ (see Fig. 1).
Rotary motion is communicated to the shaft E through the pulley E on the end
thereof.
In place of the gauze cylinder D, I may use an endless band of gauze D, as shown
in Figs. 3 and 4. In this case, the band is kept distended by the idle pulley or
drum D, which is mounted upon a stud axle D³ carried by the pendent arm D,
mounted on the sleeve F. The gauze cylinder or band D will be arranged to
move between the nozzle C¹ and the opening B, and the cylinder or the band D
revolves in the liquid fuel, and takes up, by capillary attraction, a certain quantity of
the liquid.
The blast of air entering by the inlet Cand nozzle C' will pass through the gauze to
the outlet B, carrying with it, in the form of fine spray, more or less of the liquid
fuel according to the extent of the gauze opposite the outlet B, which will be regulated
by the longitudinal shifting of the sleeve F, as before explained.
In the arrangement shown at Figs. 6 and 7, the gauze D is carried by an arm G,
which is mounted on the rock shaft G₁, suitably carried by the vessel A, and to which
a rocking motion is given in any convenient manner. The action will be practically
the same as before explained, the extent of the reciprocation regulating the quantity
of liquid fuel injected.

page_text: In the disc arrangement shown at Figs. 8 and 9, the gauze disc D is mounted on
an axle K, carried by a pendent arm K, which forms part of, or is attached to, a
sleeve K². This sleeve works in a suitable bearing in the side of the casing A, and at
its outer end is provided with a handle K³, by which it may be rocked as required.
The rocking of the sleeve in one direction or the other, will bring more or less of the
disc, D between the nozzle C and the opening B, as will be clearly understood from
the drawing.
In the sleeve K is mounted a shaft L, on one end of which is a band pulley L',
by which the shaft is driven, and on the other end a pinion L², which gears with a
spur wheel L on the axle K of the disc. By these means, the disc is slowly rotated
in front of the opening B.
The production of the blast of air forms no part of the present invention, but
it will be obvious that it may be produced by the action of the engine, and will
preferably be intermittent, or it may be by compressed air, or even by creating a
vacuum in the piston cylinder. It will also be obvious that the quantity of air
admitted should have some relation to the fuel injected, in order to ensure the most
perfect combustion, as is well understood.
I may also remark, that the propulsion or injecting of the liquid may be produced
by steam or other gaseous fluid.
In Fig. 10, H is a blow pipe, to which is attached, by the wire H', a piece of wire
gauze H2 of the requisite dimensions. The gauze is first dipped in the liquid (say
homeopathic tinctures), as shown, in order to take up the requisite quantity, and is
afterwards held over the glass containing the water with which it is to be mixed. On
blowing through the tube H, the tincture will be blown into the glass. In this way
the difficulty hitherto experienced in measuring out drops of liquid will be obviated.
Having now particularly described and ascertained the nature of ny said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In apparatus for measuring liquids, the use of a piece of wire gauze which is
to be dipped into the liquid to be measured, to hold the same by capillary attraction,
and from the interstices of which the liquid is expelled by a current of air or gaseous
fluid, as set forth.
2. In apparatus for measuring liquids, the combination of a piece of wire gauze for
holding the liquid and a pipe or nozzle for a propelling fluid, as and for the purpose
set forth.
3. In apparatus for measuring liquids, the combination with a vessel or reservoir
to contain liquid, and having an outlet opening above the liquid, of a pipe or
nozzle for a propelling fluid arranged to coincide with or opposite said opening,
and a piece of wire gauze arranged to dip into said liquid, and to be moved either
continuously or intermittently between the nozzle and the outlet opening, as and
for the purpose set forth.
4 In apparatus for measuring liquids, mounting a piece of wire gauze in a
reservoir or vessel containing the liquid to be measured out, in such a manner,
that a greater or less extent of its surface may, as desired, be brought between a
pipe or nozzle for a propelling fluid and an outlet opening in the containing
vessel, as and for the purpose set forth.
5. The arrangements of apparatus for measuring liquids as herein shown and
described.
