We, George BURGIN of No. 7 Boulters Lane, Kidderminster in the County of
Worcester, Weaver, and THOMAS CALDWELL of No. 1 Cofield Row, Stourbridge
Street Kidderminster, aforesaid, Weaver, do hereby declare the nature of our
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Our invention has for its object a new or improved needle pen whereby we are
enabled when writing with the same to keep a continuous flow of ink or other
fluid.
The great defect with the present construction of reservoir pens is the clogging
of the internal parts with the ink or other fluid contained therein, which defect we
are enabled to overcome in a reservoir pen constructed according to our invention.
In order that our invention may be clearly understood and more easily carried
into practical effect we have appended hereunto a sheet of drawings upon which we
have illustrated the same but it will be understood that variations in the shape and
design may be made without departing from the spirit of the invention.
Figure 1 is a sectional view of our improved needle pen showing the internal
parts.
Figure 2 is a view showing the pen ready for use with the cap D removed from
the front and fixed at the back.
Figure 3 is a view of the seating cap B detached from the casing A.
Figure 4 is a detached view of the point E.
Figure 5 is a detached view of the needle valve N.
The body or casing A of the pen is tapped at one end to receive the cap B which
is screwed at the end for that purpose and forms the seating for the valve n*
connected to the end of the needle N. The cap E which forms the point or pen
for writing with is also screwed into the tapped end of the casing A and fits over
the top of the point of the valve seating B. The end n¹ of the needle N to
which the valve n³ is attached passes through the point of the valve seating B
[Price 8d.1

page_text: in the interior of the cap E and protrudes slightly through the end e' of the point E.
A collar n³ is secured in a suitable position to that portion of the needle N in the
interior of the point E and a spiral spring n is placed between the said collar n
and the point 6 of the valve seating B. It will be easily understood that when the
point E is pressed upon the paper in the action of writing the end of the needle N
which protrudes therethrough will be pressed inwards thereby opening the valve n²
and allow the fluid contained in the casing A to pass out at the point b³ into the
interior of the point E by which means a continuous flow is maintained without the
internal parts becoming clogged. When pressure is removed from the point E
the spring n immediately closes the valve. An outer cap D is provided which fits
over the point E for preventing the valve from being opened when not in use but
when the pen is required for use the cap D fits on to the opposite end of the casing A
and buts against the shoulder a' which end is provided with a screwed plug a by
which means the casing A is refilled with liquid when necessary. It will be obvious
that the point E may be screwed on to the valve seating B instead of being screwed
into the casing A.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The new or improved needle pen consisting essentially of the casing A having
the seating B and point E in combination with the needle valve N substantially as
herein set forth and shown upon the accompanying drawings.
