RESERV
I, EDWARD PATTERSON, of 89, Victoria Street, Liverpool, in the County of Lancaster,
Engineer, 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 improvements in fountain or reservoir pens. Many
arrangements of such have been proposed heretofore that have been open to objections
as being expensive and complicated. Now my invention is designed to produce a
fountain pen that shall be simple and cheap to construct, it is provided with a
removable pen proper, and can be easily cleaned out (should a deposit of dry ink
lodge therein) and which has nibs sharpened or set, pointed like those of an ordinary
mechanical drawing pen.
To fully illustrate my invention a sheet of drawings is appended.
Fig. 1 shews in longitudinal section to an enlarged scale a complete fountain pen
according to my invention, and with the protector cap removed from the nib end and
placed on the other end of the feeder or reservoir tube.
the
Fig. 2. is a view also enlarged shewing the development of the sheet metal of which
pen proper is formed.
Fig. 3. is a front view of the pen proper which in this case has four nibs, and four
writing or ink flowing slits.
Fig. 4. is a side view thereof.
A. is a tubular reservoir formed as a pen holder; it is a thin tube closed at one end
and provided with an external cap or protéctor B. which can be placed on either end,
i.e. at the upper end as shewn in full lines Fig. 1. or at the lower end as shewn in
dotted lines. C. is a removable tubular extension that fits within the open end of the
tube A; it may be screwthreaded in which case the open end of the tube A,
will be formed with a corresponding thread. The other end of the tubular
extension is reduced in diameter to form a neck corresponding with the cylindrical
portion of the pen proper D, which fits inside it, and prevented from being pushed
up too far by an annular projection or ring turned or sunk into the tubular extension C,
as shewn in Fig. 1.

page_text: The pen proper D, is formed from a piece of sheet metal of a kind such as pens are
usually made of; this is cut, punched, or sheared to a shape determined by the
number of nibs or writing points it is desired the pen should have.
In the arrangement illustrated in which there are four nibs or writing points, as
shewn in plan Fig. 3, the piece of metal is of the shape shewn in Fig. 2.
Conveniently the edges E' E' of the nibs E. E. are made slightly curved inwards
as shewn, so that when the metal sheet is bent into a cylindrical or tubular shape
and the nibs E. E, are brought together at their points in an approximately conical
form by any suitable means such as blocks and dies, air slits or openings F. F. will
be left for the admission of air to the reservoir tube A, as the ink therefrom is
consumed.
It will be understood that by employing a pen proper such as herein before
described a compact body of ink may be retained within the nibs which will give a
free flow, but I do not confine myself to a pen with four nibs as illustrated; in
some cases the pen may be made with two or three, but I consider it advantageous
to form it with an even number of nibs, so that one air slit F when writing will be
upward to give free access of air. When the pen is formed with two nibs instead of
maintaining a circular form in cross section the tapered portion may be made of
approximately oval shape somewhat after the fashion of two ordinary or ruling pens
placed over each other, thus allowing free access for cleaning.
Pens with two or more nibs according to my invention instead of being made of
sheet metal as described, may be made from suitable steel or other metal tubes they
being first cut out to suit the number of nibs and afterwards blocked into the tapered
shape as illustrated.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction of a fountain pen with a tubular reservoir and a tubular pen
having two or more nibs substantially such as described.
2. In a fountain pen such as referred to in the preceding claim the construction of
a tubular reservoir closed at one end, a removable tubular extension, formed with a
neck and a tubular pen having two or more nibs, these several parts being constructed
and relatively arranged substantially as described with reference to the drawings
annexed.
3. Forming pens of sheet metal substantially in the manner herein above described
with reference to Figs. 2. and 4. inclusive of the drawings annexed.
4. My improved fountain pen as shewn and described.
