Improvements in Fountain Pens.
I CHARLES WOODBURY ROBINSON of 16 Holborn London Gentleman do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
•
This invention relates to improvements in fountain pens caligraphic pens and
consists in the proper regulation of the flow of ink to the nib or pen, which in pens
such as hitherto constructed have been found very defective. For this purpose I
screw, rivet, or otherwise fix in the end of the holder or tube, containing the ink
a plug, which may be of similar material to the tube, and which is formed with
a suitable recess for fixing a writing nib or pen therein. The upper part of this
plug is provided with a slot or opening running lengthwise thereof, into which is
placed the inner end of a wire suitably curved and bearing at its outer end which
has the shape of a spatula upon the upper surface of the nib. When the said
wire or metal strip is placed in proper position within the slot, the latter is closed
or filled up outwardly and above the wire, by means of a strip of vulcanite or
other suitable material, so as to permit the ink to pass only along the spandrel spaces
left around the wire to the nib or writing pen. The said slot may be made of a
greater width for broad than for narrow pointed nibs, so as to allow a greater amount
of ink to flow to the former than to the latter.
This improved fountain pen may be provided for the purpose of starting the feed
of ink in the nib with an elastic plug fitted at the other end of the tube or holder as
described in my former application for Letters Patent No. 3254 dated March 1st
1890.
And in order that my said invention may be more fully understood, I will
describe the same with reference to the accompanying sheet of drawings in which
Fig. 1 is a longitudinal section of my improved fountain pen.
Fig. 2 is a plan of the same.
Fig. 3 is an enlarged section of the plug carrying the writing nib or pen and the
adjacent end of the tube or holder and
Fig. 4 is a cross section on line A B of Fig. 3.
a is the tubular reservoir or holder to one end of which is fixed the plug formed
with a recess c for carrying the nib or pen d. e is a slot formed in the upper part of
the plug into which is placed a wire or metal strip f; the outer end of which is
curved as shewn so as to bear firmly against the upper surface of the nib. This
end is flattened out so as to assume the shape of a spatula as shewn at f
Fig. 2.
g is a strip of vulcanite or other suitable material fitted into the slot e above
the wire or metal strip to keep the latter in position and permit the ink from
the reservoir to pass only along the small spaces or spandrels S left around the
said wire to top of the nib or pen which is otherwise kept entirely out of contact
with the ink. The wire or metal strip ƒ may likewise be kept in position by means
of a small bent wire acting as a spring and fixed at the outer end of the plug b. The
sube a is filled by removing the elastic plug.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
