FEEDING PEN HOLDER"
PROVISIONAL SPECIFICATION left by the said Otto Bussler at the Office of
the Commissioners of Patents on the 23rd February 1882.
OTTO BUSSLER of 71 Middleton Square Clerkenwell, Middlesex Jeweller. AN
IMPROVED RESERVOIR SELF FEEDING PEN HOLDER "
This Invention consists of an Improved Reservoir self feeding Pen Holder which
is designed for containing sufficient Ink to write a large number of letters & to so
effectually regulate the flow of Ink on the Pen nib-of which any class can be
used that it will constitute a great advance on any Reservoir Pen holder now in
existence.
Several modifications of this invention can be made & various metals can be
used in its fabrication.
The Holder consists of three parts viz :—
1 Of the Reservoir marked A in the drawing accompanying this Specification.
This is the Tube in the Holder, & contains the Ink. In the lower end of the
Tube a separate Holder marked G is screwed in in which the nib is inserted.
2 The moveable Top or small Tap which is marked B in the drawing & which
regulates the flow or pressure of the Ink on the Pen nib by increasing or
diminishing the pressure of air from above.
8 The lowest part or protector of the Pen which is marked C in the said
Drawing.
The following is the method of using the Pen. Unscrew the top part or small
Tap B when this is done fill the Tube which is marked A with Ink by means of
the filler K & again screw on the top B remove the Cap C & the pen, which
hitherto remained covered, will appear; then draw out the little knob D at the
top of the small Tap B by doing which the pressure of air at once regulates the

swiftly, on account of a too strong pressure of Air pass the little knob D towards E
which will cause it to flow more gently & part B will still retain sufficient air to
cause a steady flow.
The Interior is divided as follows:-The Ink passes from A through a little hole 5
into part F & from thence through part G in which a little Spring is fixed, then
through part H into the Pen. When one discontinues writing part H closes of
itself; & it is only by writing that the action of the pen or efflux of the Ink
commences.
In selecting the Pen nib care must be taken to choose such sort as will cover 1
the little Spring Has it is only in that event that the Ink will flow, that is the
Spring in the hole H should not show through the usual aperture on the back of
the nib.
The Tube A will hold sufficient ink to permit of writing from 250-300 ordinary
sized letters.
Should there be any deposit or Sediment part G can be unscrewed at F & after
removing the little Disk marked J-which contains a very small hole & au upright
handle you can cleanse it with water using the filler K. for that purpose or you
may put the parts A & G for a short time in tepid water.

OTTO BUSSLER, of 71 Middleton Square, Clerkenwell, Middlesex, Jeweller, AN
IMPROVED RESERVOIR SELF FEEDING PENHOLDER,
This invention consists of an improved reservoir self feeding pen holder which is
designed for containing sufficient ink to write a large number of letters and so
effectually regulate the flow of ink on the pen nib of which any class can be used
that it will constitute a great advance on any reservoir pen holder.
Several modifications of this invention can be made and various metals can be
used in its fabrication. The holder consists of three parts videlicet:-
1. Of the reservoir marked A in the drawing accompanying this specification.
This is the tube in the holder and contains the ink. In the lower end of the tube
a separate holder marked G is screwed in, in which the nib is inserted.
2. The moveable top and small tap which is marked B in the drawing which
regulates the flow or pressure of the ink on the pen nib by increasing or
diminishing the pressure of air from above.
3. The lowest part or protector of the pen
drawing.
which is marked C in the said
The following is the method of using the pen. Unscrew the top part and small
tap B. When this is done fill the tube which is marked A, with ink by means of
the filler K and again screw on the top B, remove the cap C and the pen which
hitherto remained covered will appear then draw out the little knob D at the top
of the small tap B by doing which the pressure of air at once regulates the flow
of ink and it can then be used for writing: should however the ink run too
swiftly on account of a too strong pressure of air, press the little knob D towards E
which will cause it to flow more gently and part B which still retains sufficient air
to cause a steady flow.
The interior is divided as follows. The ink passes from A through a little hole
into part F and from thence through part G in which a little spring is fixed then
through part H into the pen. When one discontinues writing part H closes of
itself and it is only by writing that the action of the pen or efflux of the ink
commences.
In selecting the pen nib care must be taken to choose such sort as will cover
the little spring Has it is only in that event that the ink will flow that is the
spring in the hole H should not show through the usual aperture on the back of
the nib.
The tube A will hold sufficient ink to permit of writing from two hundred and
fifty to three hundred ordinary sized letters.
Should there be any deposit or sediment part G can can be unscrewed at F and
after removing the little disc marked J which contains a very small hole and an
upright handle you can cleanse it with water using the filler K for that purpose
or you may put the parts A and G for a short time in tepid water.

page_text: Fig. 2 consists of the reservoir marked A. The small disc marked J inserted to
prevent the too rapid efflux of the ink. The small screw marked F which is used
to join the reservoir marked A to the holder marked G. The tube marked G is
the separate holder in which the nib is inserted. The small spring by which the
flow of the ink is effected marked H.
Fig. 3 is the lowest part or protector of the pen marked C.
Fig. 4 is the moveable top and small tap being the part marked B in Fig. 1.—
1 being the small tap used to regulate the flow or pressure of the ink on the pen.
The part E being the lower portion of the tap containing a hole for the trans-
mission of air into the reservoir marked A. B is a small hole in the tap which
prevents the overflow of ink into part D.
Fig. 5 is the filler or syringe containing the ink which is transmitted into the
reservoir by means of the pressure of the india rubber ball marked K.
Having now described the nature of the said invention and in what manner the
'same is to be performed I declare that I claim as my improved reservoir self
feeding pen holder,
First. The reservoir. The holder. The disc. The small spring. The moveable
top and small tap, respectively in the manner and for the purpose substantially
herein and in the accompanying drawings set forth and described.
Second. The particular mode of transmitting and regulating the pressure of air
in connection with reservoir self feeding pen holders in the manner and for the
purpose substantially herein and in the said drawings set forth and described.
Third. In reservoir self feeding pen holders the employment of a perfectly clear
'tube and of the said several parts forming the improved reservoir self feeding pen
holder substantially as and for the purposes set forth.
Fourth. The combination of the parts forming the improved reservoir self feeding
pen holder substantially in the manner and for the purpose herein and in the said
drawings set forth and described. .
In witness whereof I the said Otto Bussler have hereunto set my hand and
seal this fifth day of September in the year of our Lord one thousand
eight hundred and eighty two.
