page_text: 1 HARRY JONES HARMAN of 36, Gaisford Street, London, N.W. in the County
of Middlesex Civil and Mechanical Engineer do hereby declare the nature of this
invention to be as follows
My improvement consists in forming a central well in the upper interior part of the
receptacle which is supplied with fluid from the lower interior portion of the receptacle
in such manner that the central well contains only a sufficient quantity of the fluid as
may be required for immediate use.
The outer casing of the receptacle may be formed of any suitable shape for the
purpose for which it is required. In the upper part of this outer casing I make a
circular or other suitable shaped opening and if the material of which the casing is
formed is not of a sufficient thickness I apply to the circumferential edge of the opening
a thin vertical band of sufficient depth to receive a part hereinafter described as the
"plunger" part. I make the plunger part of a vertical hollow circular or other
suitable shape to accurately fit the opening in the upper part of the outer casing and
of a sufficient depth for the required purpose. The upper end of this plunger part
terminates in a partially stopped end having a projecting flange on the outer circum-
ference for the purpose of lifting the part and on the inner circumference I form a
hollow conical well projecting downwards through the central portion of the plunger
part into the interior of the receptacle or outer casing.
The larger and upper end of the conical well adjoins the stopped end and the well is
male of sufficient depth and thickness for the purpose required the lower and smaller
end terminates in a stopped end which is made of a sufficient depth or thickness to
permit of it being surounded by fluid when placed in position. On the outer circum-
ference of the conical well I form a hollow vertical tube commencing at the bottom
exterior end and reaching up to any required distance above the lower interior stopped
end of the conical well at which point the tube is open to and communicates with the
interior of the well. The partially stopped end of the plunger part is provided with
a small hole of any suitable shape. When necessary I place a packing ring of India
D

page_text: rubber or any other suitable material and of a suitable shape between the plunger and
the outer casing of the receptacle for the purpose of preventing any escape of air when
the plunger is operated. This packing ring is placed in a recess formed in the
circumference of the opening in the outer casing of the receptacle or in the thin band
herein before described.
The conical well is provided when necessary with a stopper fitting into the upper
part to prevent dust and dirt getting into the interior when not in use or a lid may be
used in place thereof with a like effect.
The plunger part fits into the opening in the outer casing of the receptacle and is
removable at will for the purpose of being cleaned or to allow of cleaning the interior
of the receptacle.
In using my improvements in receptacles for fluids the action is as follows:-
The plunger part being removed the receptacle is partially filled with fluid
to a suitable depth. The plunger part is then placed in the opening and
gently pressed downwards the hole in the upper end being closed by the
finger of the hand of the person using or by any other suitable method until
the lower end of the tube reaches the fluid when the fluid passes up the tube and
into the interior of the well in sufficient quantity to fill or more than fill that pari of
the well below the upper end and opening of the tube. The hole in the upper end of
the plunger part being then enclosed any surplus amount of fluid in the well returns
down the tube back into the interior of the outer casing of the receptacle. The rising
of the fluid into the well is caused partially by the displacement of the fluid by the
lower stopped end of the conical well and partially by the compression of the air above
the fluid in the receptacle by reason of the pressing down of the plunger part but the
operation may be performed entirely by means of the compression of the air the plunger
part fitting into the outer casing sufficiently tight as not to permit of any appreciable
amount of air passing out.
When the fluid in the well has been used and requires renewing the plunger is lifted
a short distance the hole being unclosed the hole is then closed and the plunger
pushed downwards causing the Huid to fill the well as before described.
I do not intend to confine myself to the precise details of construction as hereinbefore
described as they may require to he varied according to the purpose for which the
receptacle is adapted and for convenience in use. For example the plunger may be
made a seperate part from the central well and fitted into a seperate opening in the
outer casing of the receptacle which opening may be in any convenient part of the
casing situated above the level of the flud in the interior.
The parts forming my Invention may be made of any suitable metal material mineral
or substance.
The object of my Invention is to facilitate the use of a small quantity of the fluid in
the receptacle such as may be required for immediate use without exposing the main
bulk of the fluid to the atmosphere dust or other deteriorating influences and is
intended to be used for receptacles for containing Inks or fluids used for like
purposes.
The central well containing only a given depth of the fluid waste is thereby prevented
as the pen or other instrument used does not penetrate the fluid further than is required
to fill the pen or other instrument for the time being.

page_text: Receptacles for Containing Inks and Fluids Used for like Purposes.
I HARRY JONES HARMAN of 36, Gaisford Street, London, N.W. in the County of
Middlesex, 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 :-
The object of my Invention is to facilitate the use of a small quantity of the fluid in
a receptacle such as may be required for immediate use without exposing the main
bulk of the fluid to the atmosphere dust or other deteriorating influences and
is intended to be used for receptacles for containing Inks or fluids used for like
purposes.
The central Well containing only a given depth of the fluid wasto is thereby
prevented as the pen or other instrument used does not penetrate the fluid further
than is required to fill the pen or instrument for the time being.
In the accompanying Drawing Figures 1. 2. 3. and 4. illustrate the form of my
improvements. Figure 1 is a sectional elevation Figure 2 is a plan Figure 3 is an
inverted plan of the plunger part and Figure 4 is a sectional elevation of the outer
casing of the receptacle one half shewing the application of a band D and the other
half shewing the method of applying the packing E as hereinafter mentioned. This
view also shews an external elevation of the plunger part. Like letters denote like
paris in all these figures.
My improvement consists in forming in the centre of a part hereinafter called the
plunger part a central well which is supplied with fluid from the lower interior portion
of the receptacle in such manner that the central well contains only a sufficient quantity
of the fluid as may be required for immediate use.
The outer casing of the receptacle A may be formed of any suitable shape for the
purpose for which it is intended. In the upper part of this outer casing A I make a
circular or other suitable shaped opening and if the material of which the casing is
formed is not of a sufficient thickness I apply to the circumferential edge of the
opening a thin vertical band D Figure 4. of sufficient depth to receive the plunger part.
I make the plunger part
of a vertical hollow circular or other suitable shape to
accurately fit the opening in the upper part of the outer casing A and of a sufficient
depth for the required purpose. The upper end of this plunger part terminates in a
partially stopped end having a projecting flange on the outer circumference for the
purpose of lifting the part and on the inner circumference I form a hollow conical
well projecting downwards through the central portion of the plunger part into the
interior of the receptacle or outer casing.
The larger and upper end of the conical well adjoins the stopped end and the well is
made of a sufficient depth and thickness for the purpose required the lower and smaller
end terminates in a stopped end which is made of a sufficient depth or thickness to
permit of it being surrounded by fluid when placed in position.
On the outer circumference of the conical well I form a hollow vertical tube Y
commencing at the bottom exterior end and reaching up to any required distance above
the lower interior stopped end of the conical well at which point the tube is open to
and communicates with the interior of the well.
The partially stopped end of the plunger part is provided with a small hole C of any
suitable shape. When necessary I place a packing ring of India rubber or any other
suitable material E Figure 4 and of a suitable shape between the plunger and the

page_text: outer casing of the receptacle A for the purpose of preventing any escape of air when
the plunger is operated.
The packing ring E Figure 4. is placed in a recess formed in the circumference of
the opening in the outer casing A. Figure 4. of the receptacle or in the thin band D
hereinbeforo described.
The conical well is provided when necessary with a stoppor fitting into the upper
part to prevent dust and dirt getting into the interior when not in use or a lid may be
used in place thereof with a like effect.
The plunger part B fits into the opening in the outer casing A of the receptacle and
is removable at will for the purpose of being cleaned or to allow of cleaning the interior
of the receptacle A.
In using my improvements in receptacles for fluids the action is as follows:
The plunger part B being removed the receptacle A is partially filled with fluid to a
suitable depth. The plunger part B is then placed in the opening and gently pressed
downwards the hole in the upper end being closed by a finger of the hand of the
person using it or by any other suitable method until the lower end of the tube Y reaches
the fluid when the fluid passes up the tube Y and into the interior of the conical well
in sufficient quantity to fill or more than fill that part of the well below the upper end
and opening of the tube. The hole C in the upper end of the plunger part B being
then unclosed any surplus amount of fluid in the well returns down the tube Y back
into the interior of the outer casing of the receptacle A.
The raising of the fluid into the well is caused partially by the displacement of the
fluid by the lower stopped end of the conical well and partially by the compression of
the air above the fluid in the receptacle A by reason of the pressing down of the
plunger part B but the operation may be performed entirely by means of the com-
pression of the air the plunger part B fitting into the outer casing A sufficiently tight
as not to permit of any appreciable amount of air passing out.
When the fluid in the well has been used and requires renewing the plunger B is
lifted a short distance the hole being unclosed the hole C is then closed and the
plunger B pushed downwards causing the fluid to fill the well as before described.
I do not intend to confine myself to the precise details of construction as hereinbefore
described as they may require to be varied according to the purpose for which the fluid
in the receptacle is adapted and convenience in use. For example the plunger B for
compressing the air may be made entirely distinct from the central well and fitted into
a seperate opening in the outer casing of the receptacle A which opening may be
in any convenient part of the casing situated above the level of the fluid in the
interior.
The parts forming my Invention may be made of any suitable metal material mineral
or substance.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same may be performed 1 declare that what I
claim is :-
1. Raising a portion of the fluid contained in the main receptacle to a higher level
and depositing the said portion seperately in a seperate vessel or well formed in the
upper interior part of the main receptacle.
2. Effecting the seperation of the fluid by means of compressing the air contained in
the interior of the outer casing of the receptacle or by the partial displacement of the
fluid by the plunger part acting in conjunction with the compression of the air.
3. The form and combination of the parts for the purposes hereinbefore set forth
and constructed substantially as illustrated by the accompanying Drawing.
