I FREDERICK BÖLIAN of 21 Featherstone Street, City Road in the County of
Middlesex, Manufacturers' Agent do hereby declare the nature of this invention-to-be
as follows:-
The object of this invention is to provide for the rise of draughtsmen and others a
drawing pen that will allow of being fed more speedily and effectually than is
possible by the primitive methods of feeding now in use, and require to be fed loss
frequently than ordinary drawing pens. To attain this object my improved drawing
pen is fitted with a tube made of glass, metal, vulcanised rubber, hard wood or any other
suitable material and fixed longitudinally into or upon the handle of the pen. This
tube may also be formed by boring the handle longitudinally from end to end. To the
lower end of the tube so fitted on or into lie handle a piece of very thin and pliable
india-rubber tubing of about the length of the nibs of the pen is attached in such a
manner as to form a continuation of the fixed tube already described. To the lower.end
of this pliable continuation a ferrule slightly flattened and tapering downwardly and
provided on one side with an ear-shaped projection to serve as a handle, is fixed in
such a manner round the sides of the said pliable continuation as to firmly enclose and
slightly flatten the same thereby forming a mouthpiece with a fine opening. This
mouthpiece must have such dimensions as to allow of its easy insertion into the
opening formed by the two nibs of the pen below the tightening screw, such insertion
to take place nearer to the tightening scrow when the nibs are open or set for broad
lines or nearer to the points of the nibs, when the latter are closed or set for fine lines.
A hook may be fitted to the side of the ferrule nearest to the edges of the nibs and
opposite the carshaped handle before mentioned, by means of which hook the mouth-
piece may be rested on the worm of the tightening screw and thereby kept in place.
This is not however necessary as the nibs of the pen will be found to hold the mouth-
piece sufficiently tight to prevent its slipping out.
The upper end of the fixed tube first described is closed airtight by means of an
india-rubber cap; that may. be pear or ball shaped or of any other suitable form. If
now the opening of the mouthpiece at the lower end of the pliable continuation of the
fixed tubo is dipped into the ink or colored fluid to be used for drawing and the cap
at the other end pressed together, the air contained therein and in the tube is pressed
out and on releasing the cap the tube and cap by suction are filled with ink. The
mouthpiece now placed in position between the nibs in the manner described and
the pen is ready for work. A slight pressure on the india-rubber cap at the top of
the tube will cause a sufficient quantity of ink to flow from the mouthpiece to feed
the pen.
This process is repeated as required and can be continued until the ink
stored up in tube and cap is quite exhausted.
Referring now to the accompanying drawings figures 1 to 5 represent one of the
various constructions to which my invention may be applied.
I have chosen a drawing pen with a handle the transverse section of which is
triangular, because I consider this shape of handle to be the most suitable, but my
invention is also applicable with slight modifications to handles with round, square or
polygonal transverse sections.
Figure 1 is a side elevation of my improved drawing pen. A is the handle, that
can be made of ivory, bone, wood or any other suitable material. B is a tube made
of glass, metal, vulcanised rubber or any other suitable material and secured to the
handle A by means of two metal bands bb. The tube B is provided at its upper
end B with an india-rubber cap C. To the lower end B2 of the tube B a piece of very
thin and pliable india-rubber tubing D of about the same length as the pea blades or
nibs E is attached in such a manner as to form a continuation of the tube B. The
pen blades.or. nibs E are fixed into the handle at E. To the lower part of the pliable

page_text: continuation D is fixed a ferrule F, which is slightly flattened and tapering down-
wardly and provided on one side with an earshaped projection to serve as a handle.
The ferrule F firmly encloses and slightly flattens the lower end of the pliable con-
tinuation D, forming a mouthpiece with a fine opening at D¹. is the hook, which
serves to rest the pliable continuation D with its mouthpiece F on the worm of the
tightening screw e, as fully described above.

Figure 6 shows the construction of a pen with a round handle AB, which is hollow
from B' to G. In this case the connection between the pliable continuation D.and
the tubulated handle AB is effected by means of a short ajutage G-B tapping the
tubular handle /B in G. All other parts are the same as described under figure 1
and are indicated by corresponding reference letters.
Figure 7 shows another construction of a pen with a tubular handle /B. In this
case the handle is hollow throughout, the continuation D being attached to its lower
end AB, while the socket of the pen blades or nibs is fitted into a stump handle H, the
latter being suitably secured to the side of the tubular handle B. All other parts are
as described under figure 1, and indicated by corresponding reference letters.

COMPLETE SPECIFICATION.
Improvements in Drawing Pens.
I FREDERICK BÖLIAN of 21 Featherstone Street, City Road in the County of London,
Manufacturers Agent 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 this invention is to provide for the use of draughtsmen and others a
drawing pen that will allow of being fed more speedily and effectually than is possible
by the primitive methods now in use and will require feeding less frequently than
ordinary drawing pens.
To attain this object my improved drawing pen is fitted with a tube made of glass,
metal, vulcanised rubber, hard wood or any other suitable material and fixed longi-
tudinally into or upon the handle of the pen. This tube may also be formed by
boring the handle longitudinally from end to end.
To the lower end of this tube a piece of very thin and pliable india-rubber tubing
of about the length of the nibs of the pen is attached in such a manner as to form a
continuation of the fixed tube already described. To the lower end of this pliable
continuation à ferrule slightly flattened and tapering downwardly and provided on
one side with an ear-shaped projection to serve as a handle is fixed in such a manner
as to form a mouth-piece with a fine opening. This ferrule must have such dimensions
as to allow of its easy insertion into the opening formed by the two nibs of the pen
below the tightening screw, such insertion to take place nearer the tightening screw,
when the nibs are open or set for broad lines, or nearer to the points of the nibs, when
they are closed or set for fine lines. A hook may be fitted to the side of the ferrule
nearest to the edges of the nibs for the purpose of keeping the mouth-piece in place
by resting it on the worm of the tightening screw: This is not however necessary as
the nibs of the pen will be found to hold the mouth-piece sufficiently tight to prevent
its slipping out.
The upper end of the fixed tube first described is closed air-tight by means of an.
india-rubber cap or ball. If now the opening of the mouth-piece at the lower end of

page_text: the pliable continuation of the tube is dipped into the ink or colored fluid to be used
for drawing and the cap at the upper end pressed together the air in the tube is
pressed out and on releasing the cap hoth tube and cap by suction are filled with ink.
The mouth-piece is now placed in position between the nibs in the manner described
and the pen is ready for work. A slight pressure on the india-rubber cap will cause
a sufficient quantity of ink to flow from the mouth-piece to feed the pen.
This process is repeated as required and can be continued until the ink stored up in
the tube and cap is quite exhausted, when the filling can be renewed.
Referring now to the drawings left with the provisional specification, figures 1 to 5
represent one of the various constructions to which my invention may be applied. I
have chosen a drawing pen with a handle the transverse section of which is triangular,
because I consider this shape of handle to be the most suitable, but my invention is
also applicable, with slight modifications, to handles with round, square or polygonal
transverse sections.
Fig. 1. is a side elevation of my improved drawing-pen, showing the different parts
already described. A is the handle. B is the hollow tube secured to the handle A by
means of two metal bands b. The tube B is provided at its upper end B' with an
india-rubber cap C. To the lower end B of the tube B a piece of very thin and
pliable india-rubber tubing D of about the same length as the pen blades or nibs E is
attached as a continuation of tube B. The pen-blades E are fixed into the handle A
at El.
To the lower end of the pliable continuation D is fixed a ferrule F, which is
slightly flattened and tapering downwardly and provided on one side with an ear-
shaped projection f¹ to serve as a handle. The ferrule F firmly encloses and slightly
flattens the pliable continuation 1), forming a mouth-piece with a fine opening at D.
fis the hook that serves to rest the pliable continuation D with its mouth-piece F on
the worm of the tightening screw e as hereinbefore described.
Fig. 2. is a side elevation of the same construction of my improved drawing-pen.
Corresponding reference letters indicate corresponding parts as described under
Fig. 1.
Fig. 3. is a back elevation of the same construction of my improved drawing-pen,
corresponding reference letters again indicating corresponding parts as described
under Fig. 1.
Fig. 4. represents a transverse section of the same pen at B*.
Fig. 5. represents a transverse section of the same pen at B¹.
Fig. 6. shows the construction of a pen with a round handle AB, which is hollow
from /B to G. In this case the connection between the pliable continuation D and
the tubulated handle AB is effected by means of a short ajutage, G-AB, tapping the
tubular handle AB in G. All other parts are the same as described under Fig. 1. and
are indicated by corresponding reference letters.
Fig. 7. shows another construction of a pen with a tubular handle AB. In this case
the handle is bollow throughout, the continuation D being attached to its lower
end AB, while the socket of the pen blades is fitted into a stump handle, the latter
being suitably secured to the side of the tubular handle 4B. All other parts are
as described under Fig. 1. and indicated by corresponding reference letters.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1.) In drawing pens the combination with a hollow tube of an india rubber cap or
ball for the double purpose of sucking up and expelling ink substantially as
specified.
2.) In drawing pens the combination with a hollow tube of an orifice attached to a
liable continuation of the same for the double purpose of admitting ink to the tube
nd feeding the nibs substantially as specified.
