PROVISIONAL SPECIFICATION.
A Reservoir or Fountain Pen.
ARTHUR MOWBRAY BLADES Chemist Bay Villas Chester Road, Northwich in the
County of Chester do hereby declare the nature of my invention for IMPROVEMENTS IN:
RESERVOIR OR FOUNTAIN PENS, to be as follows:-
The object of my said invention is to provide a reservoir or fountain pen that shall
be of extremely simple construction and capable of being used with any ordinary steel
or other pens.
According to my said invention I provide a tube formed of metal, vulcanite, glass
xylonite, or other suitable material the upper extremity of which is hermetically closed
forming the ink reservoir.
To the lower extremity of the said tube is fitted a short piece of tube forming a
nose piece, and containing a clip at one end to receive the pen. Into the other end of
the said short tube, I fit a cone or plug of india-rubber vulcanite, xylonite, cork or
other suitable material containing a groove along its whole length.
I also provide a small straight bar of metal or other suitable material, containing a
small deep groove or gutter, to fit tightly in the groove of the said cone or plug and
press against the underside of the pen, and short tube or nose piece.
The one end of the metal bar to reach to the middle part of the pen and the other
end to reach the ink in the reservoir.
The reservoir is filled with ink by disconnecting the nose piece and pouring it in
and replacing the nose piece.
To supply the pen with ink, it is only necessary to hold the pen downwards, when
the ink will flow down the grooved bar, and coming in contact with the inner side of
the nose piece and the inner side of the pen "capillary attraction" is set up, and the
ink flows under the influence of gravitation and adhesion to the nib of the pen, small
bubbles of air entering the reservoir from time to time as the ink in the pen is
consumed.
Any interruption in the flow may be remedied by a slight motion of the pen and
reservoir.
I sometimes provide a case or cover of some suitable material, in which. the above
described reservoir or fountain pen can be placed, or the said reservoir or fountain
pen he provided with a cap or protector to cover the nib.
In soine instances instead of the metal or other bar, I extend the length of the said
cone or plug and use the groove in it, as the conduit for the ink as aforesaid.

COMPLETE SPECIFICATION.
A Reservoir or Fountain Pen.
ARTHUR MOWBRAY BLADES, Bay Villas Chester Road, Northwhich Cheshire
Chemist, do hereby declare the nature of my invention for A RESERVOIR OR FOUNTAIN
PEN, 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 my said invention is to provide a Reservoir or Fountain Pen that shall
be of extremely simple construction and capable of being used with any ordinary steel
or other pen.
In the accompanying drawing forming part of the Specification, I have shown how
my invention can be carried into practice.

page_text: Fig. 1 is a longitudinal view of "a Reservoir or Fountain-Pen" containing my
improvements formed of metal, vulcanite, xylonite or other suitable material the
upper extremity of which is hermetically closed-A represents the reservoir B. the
nose piece.

Fig. 3 is a sectional view of plug C Fig. 2 with grooved for the supply of ink from
the reservoir to the pen.
Fig. 4. is a sectional view of nose piece B with plug Cand pen attached.

attached.
Fig. 6 is a longitudinal view of bar E showing groove D.
Fig. 7 is a section of bar showing groove D.
Fig. 8. is.a sectional view of plug to carry grooved bar E Fig. 6.
In the accompanying drawing the letter A represents the ink reservoir and
B represents the nose piece, at one end of the reservoir A and communicating with
the interior of the said reservoir.
The nose piece may be secured to the reservoir A by means of screw threads in the
said nose piece & reservoir or by other methods.
C represents the plug or cone constructed of hard india-rubber or other suitable
material. As shown in Fig. 4 the plug C passes into the nose piece B and extends
its whole length fitting tightly thus preventing the ink escaping from the reservoir
except by the groove in the plug.
When in position in the holder, the heel of the pen will pass within the nose-
piece B the pen lying on the upper side of the plug C covering the grooved and in
close contact therewith.
The ink from the reservoir A is fed to the pen along the grooved in the
plug C.
In some instances instead of using the groove in the plug C as the conduit for the
conveyance of ink from the reservoir to the pen, I use the bar E Fig. 6 made
of metal or other material and containing a groove D the bar is fitted into the
groove G of the said plug Fig. 8 which is larger than the groove shown in Fig. 7.
and projects beyond the end of the plug to the middle part of the pen as shown in
Fig. 5.
The pen is fixed by forcing the heel of the pen into the lower part of the nose piece
so that the inner surface of the pen shall cover the groove in the plug and be held
firmly by the pressure from the plug and the inside of the nose-piece.
The reservoir is filled by disconnecting the nose piece and pouring the ink in and
replacing the nose piece.
To supply the pen with ink it is only necessary to hold the pen downwards and
in some cases it is requisite to shake the pen slightly to overcome the resistance
of the atmosphere when the ink will flow down the groove in the bar, or in the
plug, when capillary action is set up and the ink flows under the influence of
gravitation and adhesion to the nib of the pen small bubbles of air entering the
reservoir through the groove in the bar or plug from time to time as the ink in the
pen is consumed.
Any interruption in the flow may be quickly remedied by a slight motion of the
pen & reservoir.
"
I sometimes provide a case or cover formed of any suitable material in which
the above described "Reservoir or Fountain Pen can be placed or the. said
"Reservoir or Fountain Pen" be provided with a cap or protector to cover the nib of
the pen.
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 :-
First. A plug or cone of bard india-rubber, vulcanite, ebonite, xylonite, celluloid
or other suitable material having a groove or gutter along its whole length and open

page_text: from end to end, fitted into the nose piece, the said groove or gutter to form the
conduit for the conveyance of ink from the reservoir to the pen.
Second. A straight bar of metal or other suitable material having a groove or
gutter along its whole length and open from end to end, the said bar is fitted into the
groove or gutter of the said plug or cone for the conveyance of ink from the reservoir
to the pen.
Third. A plug or cone of hard india rubber, vulcanite, ebonite, xylonite, celluloid
or other suitable material having a groove or gutter for conveyance of ink from
the reservoir to the pen with or without the bar of metal or other material which
shall serve for holding the pen in position instead of the nose piece having a clip for
the said purpose.
Fourth. A fountain or reservoir pen hermetically closed at one end, and having
the supply of ink from the reservoir to the pen regulated solely by atmospheric
pressure, and having no arrangement for the admission of air to the reservoir
except through the groove or gutter in the plug or bar provided for the supply of ink
from the reservoir to the pen substantially as described.
