I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to fountain pens, the object being to provide a pen of this
class of improved construction in relation to means for controlling the flow of ink
from the reservoir to the pen, and the invention consists in the peculiar construction
and arrangement of the pen-supporting and ink-feeding parts of the pen, all as
hereinafter fully described.
In the drawing forming part of this Specification ;-
Figure 1 is a side elevation, partly in section, of a fountain pen constructed
according to this invention.
Figure 2 is a longitudinal sectional view of the lower portion of the pen, excepting
the feed bar thereof which is not shown in section.
Figure 3 is a transverse section on line 3-3, Figure 1.
Figure 4 is a transverse section on line 4-4, Figure 1.
Figure 5 is a perspective view of the cylindrical pen-holding spring.
Figure 6 is a perspective view of the valve which controls the flow of ink from
the reservoir.
In the drawing, 2 indicates the reservoir of the pen, constructed preferably of
hard rubber, or similar non-corrosive material, and having its upper end hermeti-
cally closed and its opposite end open and internally screw-threaded, as shown.
The tip 3 of the pen fountain, also preferably of hard rubber, is screwed into the
lower end of the said fountain 2, as shown in Figures 1 and 2, and is thus made.
conveniently removable from the open end of the fountain for the purpose of
filling the latter with ink, B, and of adjusting the parts of the pen as below
described, which control the flow of ink from the fountain to the tip of the pen
proper 4.
The said tip 3 has a cylindrical, longitudinal passage through it from end to end,
said passage being indicated by a, and said passage a, in its upper portion or that
which is within the end of the fountain 2, when the parts are assembled as in
Figures 1 and 2, is of less diameter than that portion of said passage below the end
of the said fountain. The said upper end of the passage through the tip 3 is made
as aforesaid, of a smaller diameter than the lower end thereof to adapt it to the
diameter of the shank of the ink-feeding bar 5, said shank being adapted to fit
fairly easy in said passage and to be movable end wise therein for the purpose of
adjusting its outer end, or point, to a proper position relative to the point of the
pen proper 4.
The said upper and smaller portion of the passage a, through the tip 3, has
formed in the walls thereof one or more longitudinal grooves c, which serves to
convey ink from the reservoir through the upper end of the tip 3 into the lower
enlarged portion of the passage a in said tip, and thence along the sides of the feed
bar 5 to the point thereof, and thence to the pen 4.
The said grooves c, in the walls of the passage through the tip 3, serve as

page_text: ample coluits for the ink B which must necessarily flow unobstructedly to the
pen 4, but it is obvious that, without proper means for controlling the flow of ink
through said conduit e, (and said conduits must be of suitable depth to prevent.
them from being clogged by thick ink) an over supply of ink would be delivered
at the point of the pent, and hence there is provided, on the inner end of the shank
of the pen bar 5, an adjustable cylindrical valve 6 which may be made of any
suitable material, but rubber is the preferable one. Said cylindrical valve 6 is
movable up and down on the shank of said pen bar opposite the inner end of the
tip 3 of the pen, and said valve is of such diameter or thickness beyond the sides of
said feed bar shank, as provides for covering the upper ends of the said feed
grooves, or conduits in the inner walls of the tip 3. which adjoin the sides of snid
feed bar shank, so that if said valve 6 he moved on said shank down against the
upper end of said tip 3, the ink passages or conduits c would be entirely closed and
no ink would flow therethrough, and to secure the proper flow of ink from the
reservoir through said passages, as afore-aid, to the pen 4, the said valve is adjusted
to such position above or away from the adjoining upper end of the tip 3, as may
be necessary to permit the ink, should it possess more or less fluidity, to flow in
proper, regular quantities through said conduits e
The lower, or enlarged portion, of the passage a, through the tip 3, is adapted to
receive therein the cylindrical pen-holding spring 7, and said spring serves to hold
firmly the shank of the pen 4, when the latter is forced into said passage a
between the wall thereof and said spring 7, the latter being made preferably of
sheet metal and is held tightly in the lower end of the tip 3, by frictional engage-
ment therewith.
The ink-feeding bar, 5, extends through said spring 7, as shown in the
drawings.
The usual cap which protects the pen, 4, and adjoining parts, when the device
is not in use or arranged to be carried in the pocket, is indicated by D, the
apper end of the fountain 2, being of suitable reduced size, as shown, to receive
and hold said cap thereon temporarily. The parts of the pen are shown in the
drawing as considerably enlarged, in order to more clearly illustrate their
construction and relations.

Improvements in Fountain Pens.
A communication from abroad by WILLIAM PINNED DRAPER, of Springfield,
County of Hampden, State of Massachusetts, United States of America,
Mercliant.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.L.M.E. of the Agency for Foreign
Patent Solicitors, (i, Lord Street, Liverpool and 6, Bank Street. Manchester, both
in the County of Lancaster, & 323 11igh Hollxorn, in the County of Middlesex,
Civil 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 relates to fountain pens, the object being to provide a pen of this
class of improved construction in relation to means for controlling the flow
of ink from the reservoir to the pen, and the invention consists in the peculiar
construction and arrangement of the pen-supporting and ink-feeding parts of the
pen, all as hereinafter fully described and pointed out in the claim.
In the drawing filed with the Provisional Specification:-
Figure 1 is a side elevation, partly in section, of a fountain pon constructed
according to this invention.

page_text: the feed bar thereof which is not shown in section.
Figure 3 is a transverse section on line 3-3, Figure 1.
Figure 4 is a transverse section on line 4-4, Figure 1.
Figure 5 is a perspective view of the cylindrical pen-holding spring.
Figure 6 is a perspective view of the valve which controls the flow of ink from
the reservoir.
In the drawing
2 indicates the reservoir of the pen, constructed preferably of hard rubber, or
similar non-corrosive material, and having its upper end hermetically closed and its
opposite end open and internally screw-threaded, as shown. The tip 3, of the pen
fountain, also preferably of hard rubber, is screwed into the lower end of the said
fountain 2, as shown in Figures 1 and 2, and is thus made conveniently removable
from the open end of the fountain for the purpose of filling the latter with ink, B,
and of adjusting the parts of the pen, as below described, which control the flow of
ink from the fountain to the tip of the pen proper 4.
The said tip 3 has a cylindrical, longitudinal passage through it from end to
end, said passage being indicated by a, and said passage a, in its upper portion or
that which is within the end of the fountain 2, when the parts are assembled as in
Figures 1 and 2, is of less diameter than that portion of said passage below the
end of the said fountain. The said upper end of the passage through the tip 3 is
made, as aforesaid, of a smaller diameter than the lower end thereof to adapt it to
the diameter of the shank of the ink-feeding bar 5, said shank being adapted
to fit fairly easily in said passage and to be movable endwise therein for the purpose
of adjusting its outer end, or point, to a proper position relative to the point of the
pen proper 4.
The said upper and smaller portion of the passage a, through the tip 3, has
formed, in the walls thereof, one or more longitudinal grooves c, which serve
to convey ink from the reservoir through the upper end of the tip 3 into the
lower enlarged portion of the passage a in said tip, and thence along the sides of
the feed bar 5 to the point thereof, and thence to the pen 4.
The said grooves c, in the walls of the passage through the tip 3, serve as ample
conduits for the ink B, which must necessarily flow unobstructedly to the pen 4, but
it is obvious that, without proper means for controlling the flow of ink through said
conduits c, (and said conduits must be of suitable depth to prevent them from being
clogged by thick ink) and over supply of ink would be delivered at the point of the
pen 4, and hence there is provided, on the inner end of the shank of the pen bar 5,
an adjustable cylindrical valve 6, which may be made of any suitable material, but
rubber is the preferable one. Said cylindrical valve 6 is movable up and down on
the shank of said pen bar opposite the inner end of the tip 3 of the pen, and said
valve is of such diameter or thickness, beyond the sides of said feed bar shank, as
provides for covering the upper ends of the said feed grooves, or conduits c in the
inner walls of the tip 3, which adjoin the sides of said feed bar shank, so that, if
the said valve 6 be moved on said shank down against the upper end of said tip 3,
the ink passages or conduits c would be entirely closed and no ink would flow there-
through, and, to secure the proper flow of ink from the reservoir through said
passages, as aforesaid, to the pen 4, the said valve is adjusted to such position, above
or away from the adjoining upper end of the tip 3, as may be necessary to perinit
the ink, should it possess more or less fluidity, to flow in proper, regular quantities
through said conduits c.
The lower, or enlarged, portion of the passage a, through the tip 3, is adapted to
receive therein the cylindrical pen-holding spring 7, and said spring serves to hold
firmly the shank e of the pen 4, when the latter is forced into said passage a between
the wall thereof and said spring 7, the latter being made preferably of sheet
metal, and is held tightly in the lower end of the tip 3, by frictional engagement
therewith.

page_text: The ink-feeding bar, 5, extends through said spring 7, as shown in the
drawings.
The usual cap, which protects the pen 4 and adjoining parts, when the device is
not in use or arranged to be carried in the pocket, is indicated by D, the upper
end of the fountain 2, being of suitable reduced size, as shown, to receive and
hold said cap thereon temporarily. The parts of the pen are shown in the drawing
as considerably enlarged, in order to more clearly illustrate their construction and
relations.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
In a fountain-pen, a tip therefor having a passage therethrough to receive the
ink-feeding bar, and having one or more ink-conducting grooves in the walls
thereof, combined with said feeding-bar, a valve movable on said bar towards and
from the ends of said grooves, and an ink reservoir connected with said tip,
substantially as set forth.
