FORTUNE FRANÇOIS BENVENUTI, of Swansea, in the County of Glamorgan,
Professor of Languages, Literature and Philosophy. "IMPROVEMENTS IN THE
CONSTRUCTION OF FOUNTAIN INK HOLDERS AND OF WRITING AND RULING PENS
OR POINTS SUITABLE FOR THE SAME."
This Invention consists in certain improvements in the construction of fountain
ink holders and in writing and ruling pens or points suitable for use in connection
with the same.
The body of the ink holder is constructed of a tube of aluminium German
silver, ebonite or any other suitable material and is, by preference, made circular
in the form of an ordinary pencil holder. The exterior of the upper end of the
said ink holder is provided with a screw thread on which screws a cap provided
at its centre with an aperture for the passage of a rod which passes through the
interior of the ink holder. The said rod has formed or fixed on it a collar or flange
a short distance from the upper end, on which collar or flange rests a piston of
cork or other suitable elastic material, an aperture is made through the centre of
the same for the passage of the before mentioned rod, which is provided from the
said collar or flange to the upper end, with a screw thread. The said piston is
secured in position on the rod by means of a flange which screws on the latter and
rests or bears against the upper end of the piston. The said rod then passes
through the before mentioned aperture in the screw cap and is provided at its
protruding end with a terminating screw cap. The lower end of the ink holder is
provided with an ink feeder which has a conical or partially conical aperture
through the centre of the same for the passage of the said rod, the larger diameter

page_text: of such aperture being at the lower end, thereby providing a cushion of an inverted
tapped conical valve, with which both the ruling and writing pens or points are
provided at their upper ends as hereinafter described, and which are screwed at
the lower end of the said rod. The said ink feeder screws into the lower end of
the ink holder.
The ruling pen or point which is equally suitable for writing, screws into an
aperture in the lower end of the before mentioned rod and is of any suitable form
to a certain part thereof when it decreases gradually in size to the writing point,
on the surface of the said pen or point are a series of grooves along which the ink
flows to the pointed end. A cap or ink protector is passed over the said ruling
pen or point and is screwed on to the lower end of the before mentioned ink
feeder, the upper part of the said cap is cylindrical and the remainder decreases in
diameter with the ruling pen or point, and terminates a short distance from the
end of the latter. The pen or point, which is most suitable for writing screws on
to the lower end of the ink feeder and consists of a pointed instrument deeply
grooved or recessed in the centre to the point, it is formed partially hollow the
mouth of such hollow portion screwing on to the end of the ink feeder, covers the
opening of the same so that the ink may enter the interior of the pen and flow
through a small opening or slot to the point of the writing instrument.
When this pen is to be used, a pin terminated at its upper end by a tapped conical
flange or valve and similar to that of the ordinary stylo-point and performing the
same office, is screwed to the lower end of the said rod. This pin is of equal
diameter throughout its length, and so arranged as to pass through a portion of
the last mentioned hollow pen and to project downwards a short distance through
the opening or slot in the groove through which the ink passes.
On the upper end of the pens or points constructed as herein before firstly
described or on the upper end of the pin just described is arranged the before
mentioned inverted tapped conical valve or flange for closing and opening the
aperture at the lower end of the ink feeder, by the action of the rod to which it is
screwed, and thereby to regulate the flow of ink or other fluid.
The action of the above described fountain ink holder is as follows. When the
screw cap and with it the end of the rod, are screwed or pushed towards the body
of the ink holder, the conically shaped valve at the opposite end of the rod is
removed from its seat at the lower end of the aperture in the ink feeder, thereby
allowing the ink to flow gently from the ink holder, to the pen or point. By
reversing the action of the said cap of the rod that is to say, by unscrewing it the
said valve will be again secured against its seat and the flow of ink entirely
stopped.

FORTUNE FRANÇOIS BENVENUTI, of Swansea, in the County of Glamorgan,
Professor of Languages, Literature and Philosophy. "IMPROVEMENTS IN THE
CONSTRUCTION OF FOUNTAIN INK HOLDERS AND OF WRiting and RuLING PENS
OR POINTS SUITABLE FOR THE SAME."
My said Invention consists in certain improvements in the construction of
fountain ink holders and in writing and ruling pens or points suitable for use in
connection with the same.
The body of the ink holder is constructed of a tube of aluminium, German-silver,
ebonite or any other suitable material and is, by preference, made circular in the
form of an ordinary pencil holder. The exterior of the upper end of the said ink
holder is provided with a screw thread on which screws a cap provided at its
centre with an aperture for the passage of one end of a rod which passes through
the interior of the ink holder. The said rod has formed or fixed on it a collar or
flange a short distance from the upper end, on which collar or flange and within
the ink holder rests a piston of cork or other suitable elastic material, an aperture
is made through the centre of the same for the passage of the before mentioned
rod the upper end of which is provided with a screw-thread. The said piston is
secured in position on the rod by means of a flange which screws on the latter and
rests or bears against the upper end of the piston. The upper end of the said rod,
that is to say, the end which passes through the before mentioned aperture in the
screw cap, is provided with a terminating screw cap. The lower end of the ink
holder is provided with an ink feeder consisting of a small plug forming a con-
tinuation of the same and which has a conical or partially conical aperture through
the centre of the same for the passage of the said rod and of the ink, the larger
diameter of such aperture being at the lower end, thereby providing a cushion for
an inverted tapped conical valve with which the ruling point and writing pen are
provided at their upper ends as hereinafter described, and which are screwed at
the lower end of the said rod. The said ink feeder is screwed into the lower end
of the ink holder.
The ruling pen or point, which is equally suitable for writing, screws on to, or
into, the lower end of the before mentioned rod, the upper end of the pen or point
being bevelled so as to form a conical valve as herein before mentioned, and at a
suitable point, as will be well understood, it is made to decrease gradually in size
to the writing point, on the surface of the said pen or point are a series of grooves
along which the ink flows to the pointed end. A hollow cap or ink protector or
regulator is passed over the said ruling pen or point and is screwed on to the lower
end of the before mentioned ink feeder, the upper part of the said cap is cylindrical
and the remainder decreases in diameter with the ruling pen or point and terminates.
a short distance from the end of the latter.
The pen or point above referred to and which is most suitable for writing,
screws on to the lower of end ink feeder and consists of a pointed instrument
deeply grooved or recessed in the centre on one side, the groove or recess extending
to the point, the upper part of the pen is formed hollow, the mouth of such hollow
portion screwing on to the end of the ink feeder, covers the opening of the same
so that the ink may enter the hollow portion of the pen and flow through a small
opening or slot within the said groove or recess to the point.
When this pen is to be used, a pin terminated at its upper end by a tapped
conical flange or valve similar to that herein before described in connection with
what is termed the ruling pen or point, is screwed to the lower end of the said rod.
This pin is of equal diameter throughout its length, and so arranged as to pass

page_text: through a portion of the last mentioned hollow pen and to project downwards a
short distance through the opening or slot in the groove through which the ink
passes.
In some cases, instead of forming the last described pens or points in one piece, I
may make the upper hollow portion in the same manner but form the lower part
so as to be capable of carrying a pen of ordinary construction as will be well
understood. In this case the lower end of the ink feeder may be constructed to
pass through the centre of the carrier, a small valve being screwed on to the end of
the rod instead of employing the combined pin and valve as lastly described, by
which means the ink is allowed to flow directly from the end of the ink feeder on
to the pen. This will obviate the necessity of making the upper part of the ink
carrier hollow.
On the upper end of the pens or points constructed as bereinbefore firstly
described or on the upper end of the pin just described is arranged the before
mentioned inverted tapped conical valve or flange for closing and opening the
aperture at the lower end of the ink feeder, by the action of the rod to which it is
secured, and thereby to regulate the flow of ink or other fluid.
The action of the above described fountain ink holder is as follows. When the
screw cap and with it the end of the rod, are screwed or pushed towards the body
of the ink holder, the conically shaped valve arranged in connection with the
opposite end of the rod as herein before described is removed from its seat at the
lower end of the aperture in the ink feeder thereby allowing the ink to flow
gently from the ink holder, to the pen or point. By reversing the action of the
said cap of the rod, that is to say, by unscrewing it the said valve will be again
secured against its seat in the conical aperture or channel through the ink feeder
and the flow of ink entirely stopped.
When desired in order to facilitate a continuous flow of ink from the holder, air
is admitted to the interior of the latter through a valve arranged in the upper
part of the same or the valve may be arranged in connection with the rod. The
valve is so constructed that it can be closed when the pen is not in use.
Having thus described and ascertained the nature of the said Invention and the
manner in which the same is to be performed I would observe in conclusion that
what I consider novel and original and therefore claim as constituting my said
Invention, are:—
First. The combination and arrangement of the hollow ink holder, the rod
(having a piston on the upper end) and the ink feeder (constructed with a conical
aperture through the centre) with the ruling pen or point (having a conical valve)
and also the ink protector or regulator, substantially as and for the purposes
hereinbefore described and set forth.
Secondly. The combination and arrangement of the said ink holder, rod, and
ink feeder with the conical valve, and the writing pen or point or pen carrier,
substantially as herein before described and set forth.
And thirdly. The combination and arrangement of the ink holder with the
piston, rod and ink valve, substantially as and for the purposes hereinbefore
described and set forth.
In witness whereof I the said Fortuné François Benvenuti have hereunto set
my hand and seal this Fifteenth day of August in the year of Lord One
.
