page_text: I, JOSEPH MORRIS, of 164 Barking Road, Canning Town, in the County of Essex,
Gentleman, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of my invention is to manufacture improved fluid tight fountain
pens.
My invention consists of a tubular holder, to the lower end of which any ordinary
pen nib may be fitted and used in the usual manner.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings in which similar
letters of reference indicate corresponding parts.
Fig. 1 is an enlarged elevation of my invention. Fig. 2 is a sectional elevation
and Fig. 3 is a section of the lower end of the holder, transversely to Figs. 1 and 2.
bis a rubber sleeve
a is the tube forming the main body of the instrument.
covering a hole made in the side of the tube a against which the finger is held,
when writing. The lower end a¹ of the tube a is tapered to a point, as shown in
Fig. 2. A small opening is made at g, and this part of the tube is turned upwards
towards the pen, the underside of which it just touches. The clip d may be soldered
to the tube, or made inovable, as preferred. c is a screw cap, bored through to receive
the rod e, and enclosing a rubber disc h to render the upper end fluid tight.
The rode passes down the tube a and its lower end is sharpened or chamfered
on one side, so that when pressed down it closes the valve g and prevents the
ink flowing out. The rode has the effect of keeping the valve clear from corrosion
and solidified ink.
k are
When filling the penholder or reservoir, the pen is removed, the
cap c is
unscrewed, and the wire e withdrawn. The end g is then pressed against any elastic
substance while ink is poured in at the upper end. The rod e, cap c, and pen
then reinstated, the rod e being withdrawn from the port g about one eighth of an
inch. The pen is then ready for use. The ink percolates through the opening at g
and travels down the pen, supplying it gradually and continuously while in use.

page_text: The finger being held at f. Fig. 3. The natural throb of the finger imparts sufficient
impelling power to the ink to cause it to flow to the pen. The nib should be damped
before using the pen.
Tho tube, rod, holder and other parts may be formed of metal, vulcanite, ebonito,
other suitable material.
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 :-
1. The manufacture and use of fluid tight fountain pens, consisting of a tube a,
rubber sleeve b valve g, capable of being opened and closed by the rod e, the screw
cape and rubber disc h, and clip d severally operating substantially as hereinbefore
described and illustrated by the drawings.
2. In fountain pens the application and use of the pulsation of the finger, operating
upon the ink by means of the rubber sleeve covering an aperture f, so as to steadily
feed the ink to the pen, substantially as hereinbefore described and illustrated by the
drawings.
3. The general construction combination and. arrangement of the several and
respective parts together forming my improvements in fountain pens, substantially
as hereinbefore described and illustrated by the drawings.
