We, GEORGE WALLACE BRYANT, of 6 Christ Church Road, Gravesend, Engineer,
and THOMAS CHARLES TOWNSEND, of 80 Edwin Street, Gravesend, Engineer's Book-
keeper, in the County of Kent, do hereby declare the nature of this invention to be
as follows:-
.
This invention relates to improvements in reservoir pens, and its object is to
make a pencil pointed writing nib and arrangement whereby the filling of the
writing fluid reservoir is contained in the holder, thereby making the article self
contained.
The writing fluid reservoir consists of a glass tube open at one end and hermetic-
ally sealed at the other end, with a cap made of vulcanite or other suitable material.
The writing nib may be made of celluloid, steel or other suitable material the one
end fitting tightly into the nib casing and the other end tapered to a point and
split, the split terminating at its base in a small hole; the end fitting into the
nib casing is flattened on one side as far as the said hole, and from this hole towards
the tapered end on the same side the edges of the said split are slightly bevelled.
The writing nib casing is made of vulcanite or other suitable material with one
end to fit tightly into the reservoir casing or holder, and the other end formed with
2 pieces to project over the split in the writing nib. The reservoir casing or
holder is made of vulcanite or other suitable material with the one end to fit tightly
over the said nib casing and the other end fitted with a bush, made of lead or other
suitable material to form an air tight sliding fit over the glass tube of the before
said reservoir. A cover made of vulcanite or other suitable material for the said
writing nib point when the pen is not in use is arranged to be passed over the cap
on the said reservoir to be fitted on the said casing or holder.
When it is required to fill the said reservoir with writing fluid, the end of the
pen is placed in the writing fluid far enough to submerge the mouth of the said
nib casing; then the said reservoir is drawn out so that the shoulder on the end of
glass tube touches the said bush in the end of the casing or holder; the pen is then
inverted until the writing fluid is seen to run into the said glass tube by gravity,
the said reservoir is thus filled, the writing nib is then held downwards and the
said reservoir replaced by doing which the surplus fluid is removed leaving the pen
ready for use.

page_text: We, GEORGE WALLACE BRYANT, of 6 Christ Church Road, Gravesend, Engineer,
and THOMAS CHARLES TOWNSEND, of 80 Edwin Street, Gravesend, Engineer's Book-
keeper, in the County of Kent, 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 relates to improvements in reservoir pens, and its object is to
make the same with a pencil pointed or an ordinary writing nib and arrangement
whereby the filling of the writing fluid reservoir is contained in the holder, thereby
making the article self contained.
1
The writing fluid reservoir consists of a glass tube D open at one end and
hermetically sealed at the other end, with a cap made of vulcanite or other suitable
material.
The writing nib casing is split at the taper end or point, the said slit M terminat-
ing in a small hole or groove N towards the other end, and this end is, flattened
at O' on the one side from the said hole to the extremity; the nib casing is arranged
with the one end to fit the reservoir casing or holder A and the other end is formed
with a projecting piece oyer the slits as shown upon the drawing, Figs. 4 to 6.
The writing nib C, Figs. 7 to.9 may be made of celluloid, steel; or other suitable
material, the one end fitting tightly into the nib casing B and the other end tapered
to a point at J and split at G, the split terminating at its base in a small hole H;
the end fitting into the nib casing B is flattened on one side as far as the said hole,
and from this hole towards the tapered end the edges of the said split are slightly
bevelled (see Fig. 10). The writing nil casing B is made of vulcanite or other
suitable material with one end to fit tightly into the reservoir casing or holder A,
and the other end formed into two pieces to project over the slot in the writing
nib. The reservoir casing or holder A is made of vulcanite or other suitable
material with the one end to fit tightly over the said nib casing B and the other
end fitted with a bush E made of lead or other suitable material to form an air
tight sliding fit over the glass tube D of the beforesaid reservoir. A cover F made
of vulcanite or other suitable material for the said writing nib point when the
pen is not in use is arranged to be passed over the cap K fitted to the other end of
the casing A.
When it is required to fill the said reservoir with writing fluid, the end of the
pen is placed in the writing fluid far enough to submerge the mouth of the said
nib_casing B-then the said reservoir is drawn out so that the shoulder L on the
end of glass tube 1) touches the said bush E in the end of the casing or holder A
thus drawing in a quantity of writing fluid; the pen is then inverted until this
writing fluid is seen to run into the said glass tube D by gravity the said reservoir
is thus filled, the writing nib is then held downwards and the said reservoir
replaced, by doing which the surplus fluid is removed leaving the pen ready for use.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:_
1. The combination with a pen nib and nib casing having suitable ducts to said
nib, of a casing A open at the one end and fitted to the nib casing at the other end, a
tube Dopen' at its inner end adapted to slide tightly in said casing, a bush E there-
for, and a cap closing the outer end of tube D, substantially as and for the purpose
set forth..

page_text: 2. The combination with a reservoir D of a nib casing B fitted thereto and having
a longitudinal cylindrical passage way narrowed at the inner end, a nib C having
a cylindrical body adapted to fit the narrowed part of said passage way, having a
tapered end and slit longitudinally, the slit terminating at the interior end in a
hole having communication with the interior of reservoir D substantially as set
forth.
