An Improved Pen.
Year: 1899

page_text: An Improved Pen.
I, ROMOLO COFANI, Jeweller, of Via de Bardi 29, Florence, Italy, do hereby
declare the nature of this invention to be as follows:-
The construction upon which the characteristic principle of this improved pen
is based consists in filling with ink an elastic receptacle which is protected by a
metallic case, and when it is desired to write to cause such ink to flow by means
of the pressure exerted upon the elastic receptacle by a lever which is actuated
by the natural movement of writing. By this means the quantity of ink which
is delivered to the nib can be regulated in accordance with the greater or lesser
pressure which is exerted by the metallic nib upon the said lever, according to
whether thin or thick strokes are made.
The apparatus comprises the following parts:-
1st. The part A represented in side and front elevation in Figs. 1 and 2, which
serves to hold the metallic nib; this part is connected to the lever B shown in
front and side elevation in Figs. 3 and 4. Fig. 5 shows these two parts connected
together. When these two parts have been united, the small tube C, shown
separately in Fig. 6, is applied thereto, and the three parts are connected by
means of the pivot D, which is inserted through holes formed for this purpose in
the three parts. Then into the tubular space formed by the union of the three
parts is introduced the small end of the india rubber tube E which constitutes
the ink receptacle, and which is shown separately in Fig. 7. This tube is open
at its smaller end F and closed at the end G of larger diameter. The whole is
enclosed by the sheath H shown separately in Fig. 8. The pen is then complete;
it is shown in this form in Fig. 9. it can be used by inserting a metallic nib I into
the space expressly formed for the purpose by the two parts A and B. When
required to fill the instrument, the sheath H is removed, the india rubber tube
compressed between the fingers, and the end of the pen introduced into a
receptacle containing ink and then by opening the fingers the ink by atmospheric
pressure is caused to ascend and fill the india rubber tube E. In writing, the
simple pressure with which the metallic nib bears upon the paper is transmitted
at point to the lever B, which, turning upon pivot 1), in its turn, through its
extremity N, presses upon the india rubber tube E, and this being thus compressed
allows ink to flow to the metallic nib, in greater quantity when the stroke is
heavy, and less quantity when the writing is fine.
The pressure exerted upon the tube is very light and almost inappreciable, and
it is sufficient to cause the ink to flow. If, when the pen ceases to be used, too
great a quantity of ink has been supplied to the metallic nib, the tube takes it
back again and the metallic nib remains dry.
in order to enable the pen to be carried in the pocket it is closed by a cap 0,
shown separately in Fig. 10. Fig. 11 shows the pen closed ready to be placed
in the pocket.
The small cap O is placed upon the top of the pen when writing.

page_text: The advantages of this pen are as follows:-
1st. The ink only issues from the receptacle and flows to the metallic nib when
writing, owing to the light pressure exerted by the metallic nib upon the lever,
which pressure is proportionate to the width of the strokes made.
2nd. Metallic nibs of any quality and form may be used.
3rd. Ink of any quality, even ordinary ink, may be employed, without injuring
the pen.
4th. To fill the pen it is not necessary to employ a filler or other separate
accessory part, it being only requisite to remove the sheath and then replace
same.
5th. The pen cannot become obstructed from any cause.
6th. It is not delicate and will not be injured even when used carelessly.
7th. It is of simple construction and can be sold at a low price.

I, ROMOLO COFANI, Jeweller, of Via de Bardi 29, Florence, Italy, 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 construction upon which the characteristic principle of this improved pen
is based consists in filling with ink an elastic receptacle which is protected by a
metallic case, and when it is desired to write to cause such ink to flow by means
of the pressure exerted upon the elastic receptacle by a lever which is actuated
by the natural movement of writing. By this means the quantity of ink which
is delivered to the nib can be regulated in accordance with the greater or lesser
pressure which is exerted by the metallic nib upon the said lever, according to
whether thin or thick strokes are made.
The apparatus comprises the following parts, reference being had to the draw-
ings filed with the Provisional Specification:-
Ist. The part A represented in side and front elevation in Figs. 1 and 2, which
serves to hold the metallic nib; this part is connected to the lever B shown in
front and side elevation in Figs. 3 and 4. Fig. 5 shows these two parts connected
together. When these two parts have been united, the small tube C, shown
separately in Fig. 6, is applied thereto, and the three parts are connected by
means of the pivot 1), which is inserted through holes formed for this purpose in
the three parts. Then into the tubular space formed by the union of the three
parts is introduced the small end of the india rubber tube E which constitutes
the ink receptacle, and which is shown separately in Fig. 7.
This tube is open
at its smaller end F and closed at the end G of larger diameter. The whole is
enclosed by the sheath H shown separately in Fig. 8. The pen is then complete ;
it is shown in this form in Fig. 9. It can be used by inserting a metallic nib I into
the space expressly formed for the purpose by the two parts A and B. When
required to fill the instrument, the sheath H is removed, the india rubber tube
compressed between the fingers, and the end of the pen introduced into a
receptacle containing ink and then by opening the fingers the ink by atmospheric
pressure is caused to ascend and fill the india rubber tube E. In writing, the
simple pressure with which the metallic nib bears upon the paper is transmitted

page_text: at point M to the lever B, which, turning upon pivot D, in its turn, through its
extremity N, presses upon the india rubber tube E, and this being thus compressed
allows ink to flow to the metallic nib, in greater quantity when the stroke is
heavy, and less quantity when the writing is fine.
The pressure exerted upon the tube is very light and almost inappreciable, and
it is sufficient to cause the ink to flow. If, when the pen ceases to be used, too
great a quantity of ink has been supplied to the metallic nib, the tube takes it
back again and the metallic nib remains dry.
In order to enable the pen to be carried in the pocket it is closed by a cap U,
shown separately in Fig. 10. Fig. 11 shows the pen closed ready to be placed
in the pocket.
The small cap O is placed upon the top of the pen when writing.
The advantages of this pen are as follows:-
1st. The ink only issues from the receptacle and flows to the metallic nib when
writing, owing to the light pressure exerted by the metallic nib upon the lever,
which pressure is proportionate to the width of the strokes made.
2nd. Metallic nibs of any quality and form may be used.
3rd. Ink of any quality, even ordinary ink, may be employed, without injuring
the pen.
4th. To fill the pen it is not necessary to employ a filler or other separate
accessory part, it being only requisite to remove the sheath and then replace
same.
5th. The pen cannot become obstructed from any cause.
6th. It is not delicate and will not be injured even when used carelessly.
7th. It is of simple construction and can be sold at a low price.
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:-
The writing pen with an interior ink receptacle of india rubber substantially as
described.
