COMPLETE SPECIFICATION.
Improvements in or relating to Reservoir Pens.
1, CHARLES WALTER VOSPER, 5 Ashleigh Road, Barnstaple, in the County
of Devon, 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 has for object, certain improvements relating to pens used for
writing purposes.
In order that my invention should be understood, I make two nibs with bellied
bodies and place them next to one another in the same holder and so form a
reservoir between them, or 1 join one bellied body pen nib to one of the before
mentioned bellied body nibs in such manner that the poiuts of both nibs are close
together or touching, so that both nibs can be used as a single nib.
It will be readily understood that a pen so constructed will retain a larger
quantity of ink than ordinary pens. I also propose to make a hollow penholder
constructed with a glass tube on the inside, containing ink, and so arranged that a
supply of ink can be easily obtained by any person using the pen (suitable either
for the writing desk or pocket), a jet of ink being forced out of the glass tube to
supply the hollow or bellied,pen for ordinary writing purposes.
Description of drawings annexed hereto :-
Figure 1 represents two hollow or bellied pen nibs made alike and so arranged
face to face that when the shank ends are placed in an ordinary holder, the two
points touch each other.
Figure 2 represents the same thing only that instead of both shank ends being
set in a holder they are joined together so they can be opened for cleaning
purposes.
Figure 3 is a similar pen but has a projecting side with a slit.
Figure 4 represents a pen with projecting wings made to fit into the projecting
slits of No. 3.
Figure 5 is a representation of No. 4 turned over.
higure 6 is a drawing of a pocket fountain pen.

page_text: By my invention, if two pens are made alike and employed in duplicate and the
shank ends are each a perfect half circle that the inserting them in a round holder
opposite to each other, the points being bent inwards until they meet that the two
pens will be capable of holding a lot of ink especially if hollow, or bellied, as
described in Figure 1 of the drawings; or if a pen as described at Figure 2 with
a joint in the centre as shown at letter a and a spring in the inside of the hollow
as shown in a dotted line has a duplicate half jointed at letter e that those will
likewise meet at the points and form a reservoir or fountain pen.
C
I also make a pen with a projecting wing, as shown at Figure 3, letter d which
is slitted as shown at letter e, the corresponding half of this pen is shown at
Figure 4 and Figure 5, and has two projections, as at the latter figure, letters, f
also shown in Figure 4, letter y, those slitted projections overlap and receive the
wings of Figure 4.
I also make a holder with a reservoir on the inside, which may be made of glass
or any indestructible materials, as shown at letter H, Figure 6. I use a round
tube, and at the upper end is a piston or plunger, as shown at letter I, this can be
drawn out when the tube requires to be refilled, and to do this, it must be
unscrewed from the tube, as shown at letter J, the cap forming the cover of the
tube has a hole in the centre, through which the plunger rod passes, and which is
attached to the outside cap.
Between the outside cap and the cover of the tube, I place a spring which
when the plunger is forced into the tube for the purpose of projecting the ink
from the tube into the pens, at letter K, will force the top back into its original
position. This action can be produced by pressing the cap L with the finger.
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: The construction of pen nibs in such manner that when two of such are
placed opposite to each other in a holder the two points are in touch, as set
forth.
2. Two hollow or bellied pen nibs being made so that when they are put
together, the two points meet and with the hollow or bellied part forming a fountain
to retain a quantity of ink as described and substantially as shown at Figures 1, 2,
3, 4, and 5 of the drawings.
3. A fountain holder with glass or metallic tube so constructed that the ink can
be forced into the hollow or bellied part of two pen nibs when put together, as
shown at Figure 6 of the drawings, substantially as described.
