I ARNOLD BUDENBERG of Southgate in the City of Manchester in the County
of Lancaster Mechanical Engineer, do hereby declare the nature of my invention
for IMPROVEMENTS IN APPARATUS FOR MEASURING AND DELIVERING FLUIDS to he
as follows:-...
These Improvements relate to apparatus employed in measuring and delivering
fluids and have for their object to enable a predetermined quantity of liquid to be
drawn from the cistern reservoir or receptacle containing. it and further to
automatically arrest the outflow of liquid if desired before the full measured
quantity has been drawn off.
The liquid to be measured is by preference contained in an airtight cistern
reservoir or other receptacle but an open receptacle may be used. If an airtight
receptacle is used an opening is made therein for the purpose of refilling it and this
In the
opening may be at other times closed by a screw plug or other means.
screw plug or in any part of the closed receptacle above the highest level of liquid
contained therein an air valve is fixed which will permit the free inlet but prevent
the outlet of air.

At or near the bottom of the receptacle is fixed an outlet pipe for the liquid.
Outside the receptacle the outlet pipe is provided with a three way cock.
the cock and in communication therewith is secured an airtight vessel having a
capacity equal to the quantity of liquid which it is desired to draw off at each
operation of the apparatus. Beyond the three way cock the outlet pipe is turned
or bent downwards, for the delivery of the liquid. The passages or
ways" of
the three way cock are so arranged that when the handle controlling the cock is.
in the first position the outlet of the pipe is closed and the liquid has access to the
measuring vessel which is then filled therefrom. When the handle is moved into
the second position the "way" leading from the cock to the receptacle is closed
and the way from the measuring vessel to the outlet of the pipe is opened and the
contents of the measuring vessel are consequently discharged,

carried vertically to a point above the plane of the highest level of the liquid in
the receptacle where it is bent downwards and its lower end. made to terminate in
close proximity to the delivery orifice of the outlet pipe. The opening of the air
pipe within the measuring vessel is protected by a valve opening inwards which
will permit the passage of air in either direction but will prevent the liquid rising
into the air tube.
The action of the apparatus may be described as follows:-The handle of the
three way cock being when at rest in the first position the measuring vessel is
filled, the handle being then turned to the second position. the measured quantity
of liquid is discharged, the place of the liquid in the measuring vessel being taken
by air drawn through the air tube. Should it be desired to draw off any portion
of the fluid less than the capacity of the measuring vessel it is only necessary to
arrange that the surface of the fluid should reach and close the open orifice of the
air tube at the desired time, as for example when the receiving vessel is full. Air
can then no longer enter the air tube to take the place of the fluid in the measuring
vessel and the discharge of the liquid is therefore stopped. A small quantity of
liquid ascends the air tube until equilibrium is established and prevents further
outflow of the liquid when the receiving vessel is removed. >
The measuring vessel is preferably a short glass cylinder firmly held between
metallic discs and the cylinder may be graduated if desired. A counter may be
attached to the three way cock so as to give a record of the number of times the
apparatus has been used.
The use of the apparatus prevents waste of oil or other material in filling the
reservoirs of safety lamps and other vessels. The vessel to be filled is placed in
such a position below the outlet pipe that before an overflow can occur the rising
liquid in the vessel seals the air tube and thus stops the outflow of liquid. In
case the vessel already contains some liquid and therefore has not room for the
full. measured quantity an overflow and its consequent waste are prevented.

I, ARNOLD BUDENBERG of Southgate in the City of Manchester and County of
Lancaster Mechanical Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN APPARATUS FOR MEASURING AND DELIVERING FLUIDS and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
These Improvements relate to apparatus employed for measuring and delivering
fluids and have for their object to enable a predetermined quantity of liquid to be
drawn from the cistern reservoir or receptacle containing it and further to
automatically arrest the flow of liquid if necessary before the full measured
quantity has been drawn off.
And in order that this Invention may be more readily understood and carried
into practical effect I have hereunto appended a sheet of Drawings having the
Figures thereon marked with letters of reference similar letters denoting similar
parts in each Figure.
Fig 1 represents the apparatus in vertical section and Fig 2 shows it in horizontal
section.
The liquid to be measured is contained in an airtight cistern reservoir or other
receptacle A. In the highest part of the receptacle an opening B is formed through
which the, liquid may be supplied in bulk, this opening being at other times closed
with a screw plug C or by equivalent means. In the screw plug or in any part of
the receptacle above the highest level contained therein, an air valve D is fixed
which will permit the free inlet but prevent the outlet of air.
At or near the bottom of the receptacle an outlet pipe E is fixed. Outside the
receptacle the outlet pipe is provided with a three way cock F. Above the cock
and in communication therewith is secured an airtight vessel G having a capacity
equal to the quantity of liquid which it is desired to draw off at one operation.
Beyond the three way cock the outlet pipe is turned or bent downwards for the
more convenient delivery of the liquid. The ways of the cock F are so arranged
that when the handle H is in the normal position as indicated in the Drawings the
outlet of the pipe E to the external atmosphere is closed and the liquid has access
to the measuring vessel G which is then filled therefrom. When the handle is
turned into the second position-which as illustrated in the Drawings would be
downwards at a right angle to the position there represented as occupied by it-
the way leading from the cock to the vessel A is closed and the way leading from
the measuring vessel G is opened and the contents of the measuring vessel are
thereupon discharged.
In the top of the measuring vessel G there is fitted a small air pipe I which is
carried vertically to above the highest level of the liquid in the vessel A where it
is bent downwards and its lower open end K is made to terminate in close
proximity to the delivery orifice L of the outlet pipe E. The opening of the 'air
pipe within the receiving vessel is controlled by a valve O which will permit the
passage of air in either direction but which will prevent the liquid rising into the
air pipe

page_text: The action of the apparatus may be described as follows:-The vessel A having
been filled and the handle of the three way cock being in its normal position the
measuring vessel is filled, the handle being then turned to the second position, the
measured quantity of fluid is discharged, the place of the liquid in the measuring
vessel being taken up by air drawn through the air tube. Should it be desired to
draw off any portion of the fluid less than the capacity of the measuring vessel it
is only necessary to arrange that the surface of the fluid should reach and close the
lower end of the air tube at the desired timė as for example when the receiving
vessel is full. Air can then no longer be drawn into the measuring vessel to take
the place of the outflowing liquid and the discharge is at once stopped. A small
quantity of liquid ascends the air tube until equilibrium is established, and
prevents the further outflow when the receiving vessel is removed.
In filling safety lamps it sometimes happens that some oil or other liquid remains
in the lamp and if the measured quantity was allowed to run into the lamp it
would overflow. To prevent this the lamps are always placed in the same position
so that the outflow may be arrested before the lamp is full.
The measuring vessel is preferably a short glass cylinder firmly held between
metallic discs by bolts M and the glass cylinder may be graduated as desired.
A counter may be attached to the three way cock so as to give a record of the
number of times the apparatus has been used.
Having now. particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
(1) In an apparatus for measuring and delivering fluids the combination and
arrangement of the air pipe I, the measuring vessel G, the three way cock F and
outlet pipe E with the reservoir or vessel A all substantially as hereinbefore set
forth and described and as illustrated on the accompanying sheet of Drawings.
(2) In apparatus for measuring and delivering fluids the use of the air pipe I
substantially as and for the purpose herein before set forth and described and as
illustrated on the accompanying sheet of Drawings.
