page_text: A New or Improved Reservoir Pen.
We, BENJAMIN SUGDEN, of 16, Coulishaw Lane, Shaw, near Oldham, Relieving
Officer, and DAVID SAMUEL WILD, of 227, Manchester Street, Oldham, Poor Rate
Collector, do hereby declare the nature of this invention to be as follows;-
This invention relates to a new or improved reservoir pen, and has for its object
to provide a means whereby the penholder or handle may be utilised for carrying
a quantity of ink, which will always be ready for use, but will be unable to escape
or leak from the pen when the latter is not in use.
In constructing our new pen, the lower portion is the reservoir, and the principle
upon which our invention is carried out is that a little drop of ink is forced out
through the agency of a screw or an equivalent device when the fluid is required
for writing purposes.
When the pen is charged and ready for use a slight turn of the screw forces out
sufficient ink for the moment, and when more is required another turn is given.
The same agency which forces the ink out of the pen will also act in a reverse
direction to suck the ink up into the reservoir when it requires recharging.
In carrying out our invention we construct the reservoir of the improved pen
with a tube of non-corrodible metal, vulcanite, celluloid, or other suitable material
which will form part of the holder of the pen.
The tube is reduced at one end to a slightly smaller diameter for a short distance
along its length, and into this reduced end is fitted a plug of any suitable material.
The reduced end is extended and formed into a holder for the nib which latter is
of a non-corrodible metal.
A tube projects from the plug and terminates immediately below the split end
of the nib against which it presses lightly, and this tube conveys the ink to the nib.
The opposite end of the tube is closed by a screwed plug which is provided with
a milled portion for screwing it into and out of position.
A channel or groove is formed around the projecting part of the plug and a
tubular sheath is secured over the end of this plug by means of a short pin pro-
jecting through the sheath into the groove.
The end of the sheath which fits over the plug is preferably of the same diameter
as the reservoir case but the outer end is reduced for the remainder of its length
so as to receive the cover.
The reduced end of the sheath is of the same diameter as the extremity of the
reservoir tube and when the cover is slidden over the end of the sheath the pen is
of a uniform diameter throughout its length with the exception of the short
reduced portion near the nib.
According to one arrangement the sheath is provided internally with a longi-

page_text: tudinal feather or projection which engages with a recess in a washer or disc adapted
to slide along the tube lengthwise, but is prevented from turning relatively to the
sheath by the feather.
To the centre of this washer is fixed a long screw which passes through a tapped
hole in the plug at the end of the sheath, and projects into the reservoir tube.
At the other extremity of the screw in the reservoir is fixed a piston which fits into
the reservoir and is moved forward when the screw is revolved by turning the
sheath, thereby pressing the in through the tube on to the nib.
According to another arrangement the sheath may be formed with a projection
to engage into a recess in the disc aforementioned, the said sheath may be formed
with a vertical slot of the required length and the disc with a projection capable
of moving up and down the said slot whereby not only the equivalent mechanical
device will be obtained, but the position of the projection or pin in the slot will
also act to register the position of the piston and consequently will indicate
the amount of ink in the reservoir of the pen available for use.
Instead of having the feather in the sheath and the screw actuated by the
washer, I may fix the screw direct to the sheath, which latter is revolved in the
same manner, but will telescope over the reservoir and so the pen will be of vary-
ing lengths according to the quantity of ink in the reservoir, but in the other
arrangement described this is obviated.
Parts of the pen are specified as being of metal, but any suitable material may
be used and the outside of the case may be ornamented in any manner so as to
make it as attractive as possible.

We, BENJAMIN SUGDEN, of 16, Coulishaw Lane, Shaw, near Oldham, Relieving
Officer, and DAVID SAMUEL WILD, of 227, Manchester Street, Oldham, Poor Rate
Collector, 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 a new or improved reservoir pen and has for its object
to provide a means whereby the penholder or handle may be utilised for carrying
a quantity of ink, which will always be ready for use, but will be unable to escape
or leak from the pen when the latter is not in use.
In constructing our new pen, the lower portion is the reservoir, and the principle
upon which our invention is carried out is that a little drop of ink is forced out
through the agency of a screw or an equivalent device when the fluid is required
for writing purposes.
When the pen is charged and ready for use a slight turn of the screw forces out
sufficient ink for the moment, and when more is required another turn is given.
The same agency which forces the ink out of the pen will also act in a reverse
direction to suck the ink up into the reservoir when it requires recharging.
The combined rotary and longitudinal movement of the piston also acts to clear
the reservoir of sediment.

page_text: In carrying out our invention we construct the reservoir of the improved pen
with a tube of non-corrodible metal, such as aluminium, vulcanite, celluloid or
other suitable material which will form part of the holder of the pen. -
At one end of the tube is fitted a plug having an opening through which the
ink flows. This plug is also formed to act as a holder for the nib which is of a
non-corrodible metal.
A tube projects from the plug and terminates immediately below the split end
of the nib against which it presses lightly, and this ink conveys the ink to the nib.
The opposite end of the tube is closed by a screwed plug which is provided with
a milled portion for screwing it into and out of position.
A channel or groove is formed around the projecting part of the plug and a
tubular sheath is secured over the end of this plug by means of a short pin pro-
jecting through the sheath into the groove.
The end of the sheath which fits over the plug is preferably of the same diameter
as the reservoir case but the outer end is reduced so as to receive the cover.
The reduced end of the sheath is of the same diameter as the extremity of the
plug at the other end of the reservoir tube and when the cover is slidden over the
end of the sheath the pen is of a uniform diameter.
According to one arrangement the sheath is provided internally with a longi-
tudinal feather or projection which engages with a recess in a washer or disc adapted
to slide along the tube lengthwise, but is prevented from turning relatively to the
sheath by the feather.
To the centre of this washer is fixed a long screw which passes through a tapped
hole in the plug at the end of the sheath, and projects into the reservoir tube.
At the other extremity of the screw in the reservoir is fixed a piston which fits into
the reservoir and is moved forward when the screw is revolved by turning the
sheath thereby pressing the ink through the tube on to the nib.
According to another arrangement, the said sheath may be formed with a
longitudinal slot of the. required length and the disc with a projection capable
of moving up and down the said slot whereby not only the equivalent mechanical
device will be obtained but the position of the projection or pin in the slot will
also act to register the position of the piston and consequently will indicate the
amount of ink in the reservoir of the pen available for use.
In order to more clearly indicate the nature of this invention reference is had
to the accompanying two sheets of illustrative drawings in which
Fig. 1 is a section of a pen constructed according to this invention in the closed
position.
Fig. 2 is a plan showing the pen ready for use.
Figs. 3 to show detail views of the various parts of the pen to an enlarged
scale and,
.
Fig. 8 is a detail view showing the connection of the sheath to the reservoir tube.
Figs. 9 to 16 are similar views of a slightly modified construction.
Referring first to the arrangement shown in Figs. 1 to 8.
The tube A is formed of non-corrodible metal such as aluminium, vulcanite,
celluloid or other suitable material and forms in conjunction with other parts the
ink reservoir. The tube A is screwed at each end and plugs BC are fitted. The
plug B is reduced at b and is constructed with a recess b' into which the tube D
fits and a small opening 62 forms a passage for the ink.
The tube D is. bent over at and terminates immediately below the split end
of the nib E against which it presses lightly and this tube D serves to convey the
ink from the reservoir A to the nib E..
The plug C is formed with an extension c of slightly smaller diameter and a
groove c is formed round it in which a pin f attached to the sheath F fits. The
end of the sheath F which fits over the plug C is of the same diameter as the
reservoir case A except at fl where it is reduced to receive the cap G when the pen
is in use. The cap G fits when the pen is not in use upon the reduced portion b of

page_text: the plug B so that whether the pen is in use or not it is substantially of the same
diameter throughout its length.
A longitudinal slot f2 is formed in the sheath F and a disc or washer H is
adapted to slide within this sheath a pin h engaging in the groove f so that the
disc or washer is caused to rotate with the sheath F and can also move longi-
tudinally therein.
This disc or washer H is attached at one end of the long screw I and at the other
end of the screw is attached the piston J which fits into the reservoir A and is
moved forward when the screw I is revolved by turning the sheath F, thereby
pressing the ink through the tube D to the nib E. The piston J is packed with
hemp, silk or other suitable material, and owing to its combined rotary and longi-
tudinal movement also acts to clear the reservoir from sediment.
The plugs B and C are provided with milled surfaces
when taking the pen apart for cleaning or the like.
to facilitate unscrewing
The position of the pin h fitting within the groove f2 in the sheath F serves to
indicate the amount of ink within the pen.
In the modified arrangement illustrated in Figs. 9 to 16 the construction is
substantially similar but the plugs B and C are slightly altered in shape and the
connections with the tube A sheath F and cap G are somewhat different.
The piston Jupon the screw I is composed of the two discs jj within which a
washer or packing is secured.
Instead of having the pin in the sheath and the screw actuated by the washer,
we may fix the screw direct to the sheath, which latter is revolved in the same
manner, but will telescope over the reservoir and so the pen will be of varying
lengths according to the quantity of ink in the reservoir, but in the other arrange-
ment described this is obviated.
Parts of the pen are specified as being of metal, but any suitable material may
be used and the outside of the case may be ornamented in any manner so as to
make it as attractive as possible.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
we claim is :-
(1) An improved reservoir pen comprising a reservoir for the ink, a bent tube
for conveying the ink to the nib, a sheath by which a washer is rotated to actuate
