Improvements in the Construction of Reservoir Pen Holders.
I, STANLEY NEAL BONDFIELD WESTLAKE, of 147, College Street, Camden Town,
London, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:
This invention relates to improvements in the construction of reservoir pen
holders whereby a regular and uniform supply of ink is ensured and the degree
of supply regulated according to requirements.
My invention will be clearly understood from the following description aided
by the annexed drawings in which
Figure 1, is a longitudinal sectional view of one form of reservoir pen holder
in which the air supply is obtained by the unscrewing of a cap or screw plug
and without the employment of an air tube.
Figure 2, is a similar view of a reservoir pen holder in which an air tube is
employed.
Figure 3 is a similar view to Figure 2 but of slightly different construction.
Figure 4 is a longitudinal sectional view of the interior parts of Figure 2,
and
Figure 5 is a similar view of the interior parts of Figure 3.
The figures show the pen holder greatly enlarged to clearly illustrate the
construction.
According to Figure 1 the construction therein shown consists of a tube A
having at one end a screw cap or plug B, the other end being tapered and curved
so that its hole C is in contact with or in close proximity to the pen nib D which
is held in place by a loose sleeve E fitting on the reduced portion F of the tube A;
a capping G going over the nib end and loose sleeve E when the article is required
to be carried in the pocket.
In this figure the ink tube A is in one piece but according to Figures 2 and 3
the ink tube A is formed in two pieces A, A¹, and an air duct or tube is employed.
In Figures 2 and 3 the tube A instead of being curved at one end is made
straight and the hole C is made near one end which is closed and in connection
with the air tube H which passes up and projects through the tube A as shown.
In Figures 2 and 4 the ink tube A and air tube H (in one piece) is pushed into
and tightly fits one end of the sleeve E, this having a screw thread I at one end
for connection of the tube A' the portion of the sleeve E from that part encircling
and holding the ink tube A to the nib end being partly cut away so that only
sufficient is left to hold the nib (see dotted lines Figures 2, 3, 4 and 5) and thus
allow of nibs of any size to be used; or the sleeve may be continued as a tube
for its full length as in Figure 1. A supplementary sleeve J may encase the
sleeve E.
The construction shown in Figures 3 and 5 is similar to that shown at Figures 2
and 4 except that the ink tube A, air tube H and screw ferrule I are in one piece
and the sleeve E fits on to the ink tube A by a collar K.
In this construction a channelled strip P is fitted on the end of the ink tube A

page_text: to direct the flow of ink on to the nib D, but such channel may be formed in the
ink tube if so desired.
In Figure 1 the screw cap B is unscrewed to allow the air to enter through
between the wide screw threads to cause the ink to flow but in Figures 2 and 3
the screw cap uncovers the air tube to allow the air to enter the ink tube, and
in all cases the degree of opening of the cap B. will regulate the flow of ink on to
the nib.
M is a rubber cushion on the cap B to ensure a tight seal on the air tube end
when the cap B is screwed home to stop the air supply.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In reservoir pen holders, the combination of an ink tube A having at one
end a screw plug B, and the other end tapered and curved, a loose sleeve E
encircling such tapered end for engaging a pen nib and holding it in contact
with or in proximity to the curved end which feeds said nib, the screw threaded
plug acting as the air supply valve, as and in the manner set forth.
2. A reservoir pen, consisting of ink tubes A A¹, air tube H in a piece with
tube A, screw threaded ferrule I either as part of sleeve E or as part of tube A,
pen nib D, air supply plug B all arranged, constructed and acting substantially
in the manner set forth.
Dated this 25th day of March 1898.
