page_text: I, Dr. ADOLF HOMMEL of Zurich, Switzerland do hereby declare the nature of this
invention to be as follows:
According to this invention I construct a fountain pen holder as follows:-
Within a cylinderical lower part of the penholder is contained a piston having a
stem of elliptic section and having a screw thread formed on it. This stem passes
upward first through an elliptic hole in a disc fixed in a socket on the upper end of
the said cylindrical lower part of the holder, whereby the piston and its stem are pre-
vented from rotating, and secondly the stem passes through a screwed nut that is held
in the socket so that it can be rotated, but cannot shift up or down. To this nut is
fixed a tubular cap forming the upper part of the pen holder, and in which is con-
tained the upper part of the piston stem. Thus on rotating this cap and with it the
screw nut in one direction or the other, the piston and its stem are moved up or
down in the cylindrical part of the holder. The lower end of this is closed by a cap
formed with a socket for the reception of an ordinary steel or other pen, and it has
also a small tube projecting from it on the under-side of the pen, so that its open
outer end is situated against the latter. Thus assuming the piston to have been
moved to the lower end of the cylindrical part of the holder, then on holding the
pen holder so that the said small tube is immersed in ink, and then turning the cap
at the upper end so that the piston is drawn upward thereby, the ink will be
drawn into the cylindrical part of the holder, so as to charge this with a supply
of ink.
On using the pen holder, the cap is gradually turned in the contrary direction
so as to force the piston down-ward, thus causing the ink to flow from the tube into
the pen.
The stem of the piston can also be formed hollow, with an internal screw thread,
and the rotatable nut be situated inside it and connected by a stem to the upper end
of the cap.

page_text: I, Dr. ADOLF HOMMEL of Zurich Switzerland 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 :-
According to this invention I construct a fountain penholder as I shall describe
referring to the accompanying drawing which is a longitudinal section. In a cylin-
drical lower part C of the holder a piston K is fitted to be moved up or down. The
stem K of the piston passes through a hole in a fixed disc S, this hole and the
transverse section of the piston stem being elliptical or of other than circular form
so that the piston stem cannot turn. The stem K is screw threaded and engaged
in a nut M which is attached to the hollow upper part or cap A of the holder and is
held in position by a collar B projecting inwards from a sleeve that is soldered to the
cylinder C. The nut M can therefore be turned by turning A, but is prevented by
the stationary collar B from being displaced lengthwise. The lower end of the
cylinder las attached to it a socket H to receive an ordinary pen nib F, and from
the end of C a small tube R extends under the nib F, with its mouth opening close to
the nib near its point. When the piston K is at or near the bottom of the cylinder C,
the point of the pen is immersed in ink and then on turning in one direction the
head A and with it the nut M, the piston is moved upwards drawing a charge of ink
through the tube R into the cylinder C. When the pen is used for writing the head A
is gradually turned in the opposite direction so as to force the piston K downwards
thus causing ink to flow through the tube R to supply the nib.
The piston stem K' instead of having an external screw-thread, might be made
tubular with an internal thread, and a screw pin working in it might be attached to
the upper end of the cap A which in that case would be prevented from moving
longitudinally by a collar such as B engaging a groove at its lower end.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A fountain penholder, in a cylindrical part of which a piston can be moved up or
down by means of a nut or screw rotated by turning the head of the holder so as to
draw in a charge of ink or to discharge ink by a tube having its mouth near the
point of the pen, substantially as described.
