PROVISIONAL SPECIFICATION.
Improvements in Fountain Pens.
1, ANDREW BROWN HYDE, of Pomfret in the State of Connecticut, United States
of America, Stenographer, do hereby declare the nature of this invention to be as
follows:-
My invention relates particularly to the feed tube of fountain pens which heretofore
has been made rigid with a longitudinal ink delivering slot and said tube in resting
against the upper convex or under concave surface of the pen was not free to vibrate
with the nibs of the pen in writing.
My invention consists in the feeding tube of fountain pens constructed with trans-
verse cuts that are comparatively close together and that extend about half way
through the feeding tube destroying the rigidity of the feeding tube and making the
same flexible, so that it will bend, vield, or vibrate with the nibs of the pen in writing;
the said feeding tube remaining in contact with the surface of the pen and preventing
the occurrance of an opening between the pen and tube from which ink could
escape as would be the case with a rigid feeding tube when the pen is in use.
My improved feeding tube is made with a longitudinal ink opening, and the
transverse cuts and longitudinal ink opening are upon the same side of the feeding
tube, or on opposite sides as desired, I however prefer them on the same side.
My improved feeding tube may be round, oval, or square in cross section, but 1
prefer the round shape, and said feeding tube may be made of hard rubber or similar
material or of non-corrosive metal, and said feeding tube is secured in the holder
lengthwise and centrally of the pen, and may be set parallel to either the convex or
concave surface of the pen, or obliquely to the pen under the concave surface.
Dated this 22nd day of April 1890.

Improvements in Fountain Pens.
I, ANDREW BROWN HYDE of Pomfret in the State of Connecticut, United States
of America, Stenographer, 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 :—
My invention relates particularly to the feed tube of fountain pens which heretofore
has been made rigid with a longitudinal ink delivering slot and said tube in resting
against the upper convex or under concave surface of the pen was not free to vibrate
with the nibs of the pen in writing.
:
My invention consists in the feeding tube of fountain pens constructed with
transverse cuts that are comparatively close together and that extend about half way
through the feeding tube destroying the rigidity of the feeding tube and making the
same flexible, so that it will hend, yield, or vibrate with the nibs of the pen in writing,
the said feeding tube remaining in contact with the surface of the pen and preventing
the occurrence of an opening between the pen and tube from which ink could escape
as would he the case with a rigid feeding tube when the pen is in use.
My improved feeding tube is made with a longitudinal ink opening or slot and the
transverse cuts and longitudinal ink opening are upon the same side of the feeding
tube, or on opposite sides as desired. I however prefer them on the same side.
My improved feeding tube may be round, oval, or square in cross section, but [

page_text: prefer the round shape, and said feeding tube may be made of bard rubber or similar
material or of non-corrosive metal, and said feeding tube is secured in the holder
lengthwise and centrally of the pen and may be set parallel to either the convex or
concave surface of the pen, or obliquely to the pen under the concave surface.
In the drawing
Figures 1 and 2. represent longitudinal sectional views of my improved fountain
pen, and
Figure 3 is a longitudinal section of the end cap.
Figure 4. is a cross section at X X of Figure 1, and
Figure 5. is a cross section at y y of Figure 2 and
Figures 6. 7. 8. 9. 10 and 11. are detail views of the feeding tube.
a, represents the cylindrical ink reservoir and handle having a contracted end a².
b. represents the cylindrical removable end adapted to hold the pen and c. is a
cylindrical cap adapted to fit over the end b. when the pen is not in use, and to be
removed and placed upon the end a when the pen is to be used in writing.
These parts are as usual made of hard rubber although other similar material may
be employed if desired.
The cylindrical end b. screws into the end of the reservoir or handle a. in the usual
manner.
The outer end of the pen holding portion b. is longitudinally perforated with a
curved opening for the pen d. an air hole e. and a holo at f. for the feed tube s.
In Figures 1. and 4. the air hole e, is under or adjacent to the concave surface of
the pen and the hole. and feeding tube 8. are over or adjacent to the convex surface
of the pen while in Figures 2. and 5. the paris are reversed.
The feeding tube s. may he round square or oval in cross section but I prefer the
round form, and the same may be made of hard rubber or similar material or of a
non-corrosive metal.
The feeding tube s. is made with fine transverse cuts that extend through about
one half to three quarters of the diameter of the tube sufficient to make the same
flexible and with a longitudinal opening or slot for the delivery of ink to the pen.
The transverse cuts and longitudinal ink slot are by preference made in the same side
of the tube s. as will be seen by reference to Figures 1. 2. 6. and 8, or they
may be placed on opposite sides as shown in Figures 9. 10. and 11.
The ink slot i. may be long, as shown in Figures 1. 2. 6. & 9. or short as
shown in Figures 8. & 11. without departing from my invention.
The feeding tube s. is secured in the end of the holder b. lengthwise and
centrally of the pen and said tube is preferably set parallel to the convex surface
of the pen as shown in Figures 1 & 4. but may be set parallel to the concave
surface of said pen; or if desired the said feeding tube may be set obliquely to
the pen under the concave surface as shown in Figures 2. and 5.
In either position I prefer to place the side having the transverse cuts and ink
slot next to the pen.
The parallel feeding tube s. shown in Figure 1. will yield as the pen d bends in
the act of writing.
The feeding tube s. shown in Figure 2 is not only obliquely set to the
pen but is curved downwardly where it is set against the under surface of the pen
and the transverse cuts at this point are slightly opened.
The object of this is to keep the feeding tube against the pen and permit the
tube to follow the nibs of the pen as they bend in writing the tube straightening
as the nibs of the pen bend and vice versa.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
First. In a fountain pen, the feeding tube s. having transverse cuts which inake
it flexible so that it may spring up and down with the vibration of the nibs of
the pen d substantially as described and for the purpose sot forth.

page_text: Second. In a fountain pen the combination with a reservoir a. and removable
pen holding end b. having an air hole e of the pen d and the feeding tube s.
having transverse cuts and a longitudinal ink opening, substantially as described.
Third. In a fountain pen the combination with a reservoir a and removable pen
holding end 6 having an air hole e, of the pen d. the feeding tubo s. having transverse
cuts and a longitudinal ink opening or slot, the said tube being set lengthwise
and centrally with the pen and parallel to the convex surface substantially as set
forth.
Fourth. In a fountain pen the combination with a reservoir a and removable pen
holding end b. having an air hole e, of the pen d. the feeding tube s. having transverso
cuts and a longitudinal ink opening or slot, the said tube being set in a curved position
obliquely to the pen under the concave surface substantially as set forth.
