PROVISIONAL SPECIFICATION left by the said John James Ridge at the
Office of the Commissioners of Patents on the 5th February 1883.

IMPROVEMENTS IN SELF ACTING OR FOUNTAIN PENS AND THEIR HOLDERS
"
This invention relates to improvements in self acting or fountain pens and their
holders and consists essentially of forming a reduced aperture in the neck of a
holder to act as a check valve to prevent an unnecessary flow of ink to the nib or
other writing point.
In connection with the reduced neck or check valve I purpose fitting a nib or
writing point binged or jointed to the neck portion in such a manner that it turns
or moves on the hinge pin or pivot that its back or upper end is caused to bear
against a flexible portion of the reservoir to press the ink through the aperture to
the nib or point-while the writing progresses
If the nib or writing point is not hinged or pivoted or otherwise supported by
the bolder the flexible portion is so arranged that the thumb or finger shall press
thereon to ensure the requisite flow.
The holder may be enclosed in an outer casing as a protection to the flexible
portion and to facilitate the pen being carried in the pocket.

"IMPROVEMENTS IN SELF ACTING OR FOUNTAIN PENS AND THEIR HOLDERS
This Invention relates to improvements in self acting or fountain pens and their
holders, and consists essentially of forming a reduced aperture in the neck of a
holder to act as a check valve to prevent an unnecessary flow of ink to the nib or
other writing point.-In connection with the reduced neck or check valve I purpose
fitting a nib or writing point hinged or jointed to the neck portion in such a
manner that it turns or moves on the hinge pin or pivot that its back or upper
end is caused to bear against a flexible portion of the reservoir, to press the ink
through the aperture to the nib or point while the writing progresses.-If the nib
or writing point is not hinged or pivotted or otherwise supported by the holder
the flexible portion is so arranged that the thumb or finger shall press thereon to
ensure the requisite flow.-The holder may be enclosed in an outer casing as a
protection to the flexible portion and to facilitate the pen being carried in the
pocket.
Having thus far described the nature of my Invention I will now proceed by
reference to the accompanying Drawings to further and particularly describe and
accostuin in what manner the same is to be performed.

on the tail of the rocker, which in its turn presses on the india rubber tube; by
this movement the interior of the holder is rendered smaller, and the ink which it
contains is squeezed out through the narrow bore of the nozzle to supply the nib.-
As soon as the pressure is taken off, the tube recovers its usual size and sucks back
all excess of ink, together with a sufficient quantity of air to replace the ink which
remains between the end of the nozzle and the nib-In another arrangement, the
tail of the rocker is dispensed with, and the butt of the nib presses directly upon
the india rubber reservoir.
Another arrangement consists in the pins on each side of the holder, forming
pivots for the rocker, same being balanced upon them, the pen being clamped to the
rocker by a ring or other device.
In Fig. 7, A is a rod of wire or vulcanite tipped at the end B with india rubber,
and at the other end passing through a hole in the vulcanite and ending in a
button C This hole in the plug is enlarged at its inner part and the rod there
passes through a tube of india rubber, which is cemented to the plug.-When the
pen is to be used, the rod is pulled slightly out by the button.-When it is to be
closed, the button is pushed down and the end B is thus pushed into the hole of
the rocker, which is countersunk to receive it. Thus the ink cannot be forced out
through the nozzle until the button is raised.
Having now particularly described and ascertaine the nature of the said
Invention and in what manner same is to be performed, I claim the Invention of
Improvements in self acting fountain pens and their holders," substantially as
described, and specially the contracted nozzle D and the action of the butt end of
the nib pressing directly or indirectly on reservoir, substantially as and for the
purpose described.
In Witness whereof I the said John James Ridge have hereunto set my hand
and seal this third day of August in the year of our Lord one thousand eight
hundred and eighty three.
