IMPROVEMENTS IN FOUNTAIN OR RESERVOIR PENS
Year: 1884

page_text: We JOHN HODGES and WILLIAM BARTLETT WARREN of 42 Kirby Street in
the County of Middlesex, India Rubber Manufacturers do hereby declare the nature
of the said Invention for IMPROVEMENTS IN FOUNTAIN OR RESERVOIR PENS
to be as follows:-
"
"
The essential features of this Invention are that a long tube is employed inside
the barrel reaching nearly to the top of it and having a slit extending through its
whole length so as to form a connection with the interior of the tube.
The end of the tube rests upon and delivers the ink to the back of the pen nib.,
The other parts of the pen are of the common and well known construction.
By these means we find the ink will flow freely without the need of knocking or
shaking the pen or making a hole in the top of the barrel.
We JOHN HODGES and WILLIAM BARTLETT WARREN, of 42 Kirby Street, in the
County of Middlesex, India-rubber Manufacturers, do hereby declare the nature of
this Invention for "IMPROVEMENTS IN FOUNTAIN OR RESERVOIR PENS" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :---

or shaking the pen or making a hole in the top of the barrel for the admission of
air.
,
In the accompanying Drawings Figure 1 is a longitudinal section of the complete
pen. Figure 2 is a side view of the tube and Figure 3 is an end view or cross section
of the same. Figures 1 and 2 are about double the size of the ordinary pen and
Figure 3 four times as large for the sake of clearness.
A 18 the barrel or reservoir of the pen, B is the tip which screws into the barrel
as shown C is the tube fitting closely in the hole through the solid portion of the
tip B and pressing with its projecting end upon the pen nib D which is thereby
firmly held in the open end B of the tip B. The pen nib should be pushed in as
far as it will go so as to cover the exposed portion of the slit C².
All this is clearly shown in Figure 1. The tube C can be withdrawn from the
tip B at pleasure.
Upon reference to the Drawings it will be seen that the tube C is slit up its
entire length at C³, C¹ being the hole down its centre. Its projecting end C³ is
turned partly over so as to present the hole C¹ fair to the pen nib so as to deliver
the ink freely, to the back of the nib and preferably directly to the small slit or
opening D' usually found in pen nibs. By this general arrangement and the slit C³
in the tube C it is found that the ink readily flows to the pen nib without the
necessity for a hole in the barrel for the admission of air or the knocking and
shaking commonly required.
E is an air hole in the solid portion of the tip B¸ to facilitate the escape of air
while screwing in the tip. The visual shield or cover F is shown in dotted lines and
can be placed upon the top of the barrel at A' when not required to protect the
point.

We do not bind ourselves to any special materials for use' in making these pens
but the ordinary vulcanite does very well.
Having now described our invention and the method of performing the same we
claim
7. ..
1. In a reservoir pen substantially as described the employment of the long
tube C which extends approximately to the extreme end of the reservoir.
2. The employment of a tube C having a slit C' communicating with the central
bore and extending throughout the whole length of the tube substantially as
described and shown in the accompanying Drawings.
3. The method herein set forth of supplying the ink to the back of the nib.
