"IMPROVEMENTS IN WRITING INSTRUMENTS.'
"
This Invention relates to improvements in what are commonly known as
stylographic fountain pens, and consists, firstly, in the application of a needle
wire, which (extending through the whole or greater part of the instrument and
being of a uniform thickness throughout its entire lenght) serves as vibrating by
its own inherent elasticity without the forming of such wire into spring, or as
non-vibrating according to the will of the writer; secondly, in the application of
a peculiar formed regulating plug, whereunto or into such needle wire is
permanently secured, such plug being the means of simultaneous regulation of the
tension of the needle, wire and the air supply.
According to one mode of my Invention I employ a hollow tube made of any
suitable material to hold the ink; one end carries a tapered or otherwise
conveniently formed writing point, made of any suitable and preferably of a ductile
and non-corrosive material that will allow of a fine parrallell hole being moulded,
The other end of
drawn, or otherwise conveniently formed through its centre.
the tube has a peculiar formed plug, one end of such plug is formed into a tapered
or otherwise formed valve screw, screwing into the inside of the tube in order to
close or open so as to admit or exclude the air to or from the ink chamber; the
other end of such plug is thus shaped, that an open space is formed between the
plug and the inside wall of the tube; this space serves as the expansion chamber.
The plug extends beyond the tube to allow its being adjusted; to such plug I
permanently secure a minute wire made of any suitable material and preferably of
inetal. This wire is of a uniform thickness throughout its entire length (extending
from the top of the instrument and passing through the minute hole in the point),
pertrudes a certain distance beyond the point in order to serve as vibrating (as is
well understood in the act of writing) by its own inherent elasticity, without the
employment of a seperate spring or the forming of such wire into a spring. It
entirely depends upon the distance such wire is pertruding through the hole in the
writing point to cause such wire to vibrate much, little, or not at all, either action

instrument is as follows:-The plug is unscrewed, the holder filled with ink, the
plug being replaced again, its attached wire passing through the whole of the
instrument pertrudes a certain distance beyond the writing point. A slight turn
of the plug will tend to admit air to the ink and also adjust the needle wire,
which whilst pertruding through the writing point will cause the needle to vibrate
throughout its entire length by its own inherent clasticity, in the act of the
extreme end of such needle wire being brought into contact with the writing
surface;
it entirely depends upon the adjustment of the plug to cause the wire to
vibrate much, little, or not at all, and this is solely effected by turning the plug
either one way or the other according to the will of the writer. The expansion
chamber will receive any particles of ink that may tend to escape the ink chamber
in the act of the plug being adjusted.
Having thus described and illustrated the nature of my Invention, I do hereby
state that the novel and essential feature of my Invention is,―
That the air supply as well as the needle wire can be regulated simultaneously
in order to use the needle wire, which is of a uniform thickness throughout its
entire length, as vibrating by its own inherent elasticity without the forming of
such wire into a spring, or as non-vibrating, either action being regulated by the
turning of a peculiar formed regulating plug either one way or the other by the
will of the writer.
