PROVISIONAL SPECIFICATION.
An Improved Reservoir Pen.
CYRUS COPUS 22 Clapham Road Kennington in the County of Surrey, Castor
Manufacturer, do hereby declare the nature of this invention to be as follows:
-
My invention is a writing pen with reservoir for ink, contained within the
holder for the transferring to paper, by means of the usual nib.
The holder is a hollow tube A, taper or straight shape, as shewn in Figs. 3 and 4
and can be made of wood metal glass vulcanite or other suitable material.
The top and bottom of this tube is tapped with a screw as shewn in Fig. 3 & 4.
The top portion B is a funnel shaped tube, acting as an air chamber with screw
outside, part of which screws in top tube A, and the other half receives cap D.
Figs. 11 & 12.
In cap D there is a hole in top to allow of the spindle E Fig. 7. to regulate the
supply of ink.
The bottom end of tube A is fitted with a conical nozzle, having a tapered hole
as in Figs. 9 & 10, in order to allow the free passage of ink to flow from tube A,
and a screw outside nozzle C. Figs. 9 & 10 to fix the same in bottom of holder A.
On the tapered end of tube A is fixed a ring, F Fig. 8, to keep the nib in
position.
The spindle E Fig. 7 is a piece of wire, with a nob on top, the bottom part
being tapered, of plug shape, the wire thinned, so as to pass through the fine hole
in nozzle C Fig. 9 & 10 with a screw above to regulate the supply of ink, and
also to stop the same when required, by the turning of the spindle by means of the
nob at top.
The holder can be filled with ink at the top by unscrewing cap D. Caps G
Fig. 13 & 14 are for protecting nib of pen.
This pen is regulated entirely by the spindle E, and a free flow of ink can always
be obtained when it is unscrewed a little by means of the nob at top. It is
impossible to get corroded, for when screwed up after being used, the hole is cleared,
and is thus free at any time to write with after unscrewing the spindle till the ink
flows, and then regulating the supply by turning of nob.
This same pen can be fitted with lead pencil and india rubber attachment, by the
means of caps as shewn in Figs. 15 & 16.

CYRUS COPUS 22, Clapham Road Kennington London S. W. Castor Manu-
facturer 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 :-
My invention is a writing pen with reservoir for ink contained within the holder
for the transfering to paper by means of the usual nib.
The holder is a hollow tube A taper or straight shape, as shewn in Fig. 3 & 4
and can be made of wood, metal, glass vulcanite, or other suitable material.
The top and bottom of this tube is tapped with a screw as shewn in Fig. 3 & 4.
The top portion B. is a funnel-shaped tube acting as an air chamber, with screw
outside part of which screws in top tube A and the other half receives cap D
Fig. 11 & 12.

In cap D there is a hole in top to allow of spindle E Fig. 7 to work and regulate
the supply of ink. The bottom end of tube A. is fitted with a nozzle, having a
tapered hole as in Fig. 9 & 10 in order to allow the free passage of ink to flow from
tube A. Outside the nozzle is a ring, cap, or holder to keep the nib of pen in
position.
The spindle E Fig. 7 is a length of wire with a nob on top, the bottom part being
tapered of plug shape screw, the wire thinner, so as to pass through the fine hole
in nozzle Fig. 9 & 10, with a screw above to regulate the supply of ink, and to
stop the same when required. The holder can be filled with ink at the top by
unscrewing caps D. G Fig. 13 & 14 are for protecting nib of pen.
This pen is regulated entirely by the spindle E and a free flow of ink can always
be obtained by turning nob at the top. It is impossible to get the passage stopped
by corrosion, for when screwed up after use the hole is cleared every time.
The drawings herein referred to are those filed with the Provisional.
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. A reservoir pen with screw spindle that acts in regulating the supply of ink,
and also shuts off the same when required. It is impossible for the supply of ink to
be stopped through corrosion as the spindle always clears a passage for the ink to
flow through, and keeps the ink air tight when closed.
Dated this 11th day of December 1890.
