page_text: An Improved Fountain Penholder.
I, FREDERICK STIVENS COCKER, of Holyport, Maidenhead, in the County
of Berks, Gentleman, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved fountain penholder adapted for use with
ordinary pen-nibs, and whereby an unfailing supply of ink may be ensured the flow
of the ink to the pen being under the immediate control of the hand which holds
the instrument.
The fountain or reservoir to contain the ink is a tube partly of rigid material,
preferably glass, celluloid, or other transparent substance and partly of elastic or
compressible material, such as india-rubber united by any suitable means, the rigid
part of the reservoir either being adapted to form the casing for the flexible part,
or the whole being contained within a tubular casing adapted to form a holder for
the pen-nib and having an aperture at which part of the compressible tube is
exposed to the pressure of the writer's thumb or finger. The rubber tube
terminates in an ejecting orifice or nozzle which may be formed at the end of the
compressible tube itself, or be separately made of any suitable material the orifice
being so situated within the hollow of the pen as to cause the ink ejected therefrom
to pass directly into the pen. The upper end of the glass tube is provided with a
removable stopper or cap at which the reservoir is filled and which may be in the
form of a bulb so as to itself constitute part of the reservoir capacity.
In order to prevent leakage when the instrument is not in use a clip is provided
which is adapted to press on and throttle the compressible tube near the ejection
orifice, said clip being brought into action by an adjustable guard or cap for the
pen-nib.
In order to prevent excessive supply of ink to the pen by the involuntary pressure
on the compressible tube in writing, the aperture in the casing at which the com-
pressible tube is exposed, may be so situated that a slight twirling movement of the
penholder between the thumb and forefinger in the intervals of writing is requisite
in order to bring the compressible tube under the pressure of the thumb.
When the bulb or bottle form of cap is used for the reservoir, it may be adapted
to form a means of refilling, a number of such bulbs charged with ink and
temporarily corked being provided so that a full one may be substituted for an
empty one whenever required.
The body of the bulb would be sufficiently rigid to resist pressure whilst the neck
of the bulb would be elastic and sprung on to the end of the tubular reservoir so as
to make a tight joint therewith whilst permitting of a sliding motion of the bulb on
the tube either for the purpose of ejecting ink or for withdrawing into the reservoir
a superfluous quantity supplied to the pen.
For pocket use the casing may be made of two parts hinged so as to admit of
folding the elastic part of the tubular reservoir adapting itself readily to this
motion.

page_text: I, FREDERICK STIVENS COCKER, of Holyport, Maidenhead, in the County
of Berks, Gentleman, 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 :-
This invention relates to an improved fountain penholder for ordinary pen nibs,
by means whereof an unfailing and uniform supply of ink to the nib is ensured, the
flow of the ink to the nib being under the immediate control of the hand in which
the instrument is held whilst writing.
The invention presents the further advantages of a large reservoir capacity, ease
of refilling, and the entire absence of leakage to which other fountain peus now in
use are liable, so that my improved pen may be safely carried in any position in
the pocket.
The invention is illustrated in the accompanying drawings, forming part of this
Specification, wherein Figure 1 is an external view, Figure 2 a longitudinal section,
and Figure 3 a cross-section of the preferred form of penholder, the two former
figures being drawn about double, and Figure 3 about four times, full size.
Figure 4 shews a part sectional view of a modified form of the pen, drawn
about double full size. The same letters of reference denote like parts in all
the figures.
The fountain or reservoir to contain the iuk is partly composed of a tube A, A',
forming the holder or casing and partly of an elastic or compressible liner tube B
open to the part A' and contained within the part A, from an opening in the side
of which the flexible liner is caused to project as at 6 by an internally projecting
boss a within the tube A at the opposite side to the said orifice a. The
compressible liner tube B terminates in an ejection orifice formed by a longitudinal
groove c in a plug C which fits in the open end of the tube B, the orifice being
so situated with regard to the hollow of the pen nib that the ink ejected will
flow directly into the latter.
In order to prevent leakage when the instrument is not in use, a clip d of
Lshape is provided, the shorter limb of which is adapted to throttle the rubber
tube at the ejection orifice by its end pressing the tube inwards against the
bottom of the groove c, as shewn in dotted lines, said clip being so pressed
inwards by the guard cap E for the pen nib which is applied when the pen is
to be carried in the pocket. The elbow of the clip d is rounded, as shewn, so
as to present an inclined outer surface to the lip of the guard cap, and is thus
caused when the cap is passed over it to pass by its inwardly turned end directly
against the compressible tube. This clip is held in position by its longer limb
being lodged in a slot d in the tube A wherein it is confined by said slot being
partly covered by an encircling ring D attached to the tube A as shewn.
When the guard cap is removed the clip is forced outwards by the elasticity
of the tube B so as to leave the orifice of that tube free to permit the ejection
of ink by the pressure of the writer's thumb upon the projecting part b.
b
In order to prevent excessive supply of ink by involuntary pressure in writing,
the aperture a at which the part & projects is so situated as not to be normally
pressed upon by the fingers, a slight twirling movement of the penholder between
the thumb and fore-finger being necessary to bring the part 6 under the pressure
of the thumb in the interval of writing.
The elastic tube B is secured in position in the tube A by the lower portion of
its length being encased in the thin metal ferrule B', a tongue b¹ cut or stamped
therein being bent outwards after the tube B has been put in place so as to
engage with the upper end of the slot d against which the tongue b' is held by

page_text: the clip d for the passage of whose shorter limb an aperture is also cut in the
ferrule.
The parts A, A, are preferably made of vulcanite and united by the spigot
end of the one fitting tightly in a socket in the other, the joint being completed
by an external covering formed by a band or short length of stout soft india-
rubber tube G. The length of the spigot and socket joint between the parts A, A¹,
is sufficient to permit of a sliding or telescopic motion of the parts thus connected
for the purpose of ejecting ink into the pen nib at starting or of withdrawing
into the reservoir any superfluous ink supplied to the pen. In order to fill the
reservoir, the parts A, A¹, are separated and the part A¹ which is closed at the
upper end may be filled by merely pouring in the ink through a funnel.
Instead, however, of the parts A, A', being separable by an intermediate joint,
they may be permanently connected or in one and the part A' may have a
removable sliding plug at the upper end connected to it by a joint similar to
that shewn in Figure 4, thus permitting of the ejection and withdrawal of ink,
as previously described. The plug is removed for filling the reservoir when
necessary.
The end of the part A is adapted to receive and hold the pen nib in the
ordinary way, the hollow underside of the nib being in direct contact with the
soft rubber tube B for which purpose the ferrule B' is cut away at its lower
extremity on that side which is in contact with the pen nib.
The guard cap E may have fixed within it a pad of rubber e by which to
wipe the interior of the pen nib when required in order to clean it or induce the
flow of ink to the point of the nib at starting.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved fountain penholder constructed to act substantially as and for
the purpose specified.
2. A fountain penholder consisting partly of a tubular reservoir or casing of
rigid material and partly of a flexible liner tube adapted to project from a lateral
aperture in the casing, the liner being open at the inner end to the reservoir and
provided at the outer end with an ejection orifice formed by a grooved plug, and
the rigid casing being made in two parts connected by a telescopic joint whereby
to effect the ejection and withdrawal of ink, as specified.
3. The combination, with the fountain penholder constructed as specified in
Claim 2, of a presser clip adapted to throttle the ejection orifice by pressing the
soft rubber tube into the groove of the plug, the clip being self-releasing and
adapted to be pressed into operative position by the guard cap, as specified.
