The stylograph according to the present inven

essentially in that in front of the orifice of the
nozzle and overlapping it a small knob is located,
so that the ink cannot issue from the tube other
wise than below the knob in a lateral direction

"may be mushroom-shaped and be seated on a

What we claim is:-'
1. A stylograph with a small nozzle on the writ
ing end conveying ink from the ink chamber to
the surface to be written upon, having inside the
nozzle a wire stem provided with a small knob on`
its outer end, the said small knob being seated in
front of the orifice of the nozzle and overlappingA
it, and having an ink conduit pipe,`and a remov
able plug of elastic material fitting closely in the
10 mouth piece of the holder inside which the ink
conduit pipe is mounted, whereby said nozzle is
yieldingly supported for oscillatory movement
while writing.
`
2. A stylograph according to claim 1, charac
terized in that at least one air-conducting fur
row is cut along the plug.
3. A stylograph according to claim 1, charac
terized in that the outer wall of the rubber plug
is covered with a thin layer of a material per
20 mitting the rubber piece to slide within the mouth
piece of the holder.
4. A stylograph according to claim 1, in which
the plug is retained in the holder solely by the
elasticity of its material.
5. In a stylograph, an ink chamber and a plugA
substantially closing the chamber, a small tube
for supplying the ink from the ink chamber to
the writing surface, a small knob seated in front
of the orifice of the small tube and~ overlapping
the same leaving a narrow but sufliciently large
slot between the knob and the edge of the small
tube for the . outflow of the ink, the writing ink
being adapted to flow out along the small knob
in a lateral direction, a short wire stern arranged
in said tube to which said small knob is fastened
and said plug having channels extending along
the orifice of the writing point through which
the air can pass into the ink chamber of the
writing point, said air replacing the ink used
when writìng.`
