Improvements in Fountain Pens.
I, CHARLES EATON BROWNING, of 139 Huron Street, Toledo, Ohio, United
States of America, Manufacturer, do hereby declare the nature of this invention
to be as follows :-
This invention relates to certain improvements in fountain pens.
The object of the invention is to provide a fountain pen exceedingly cheap,
simple and durable in construction and composed of a minimum number of parts,
and wherein a perfect and continual flow of ink will be produced without flooding
or dropping of ink.
The invention consists in certain novel features of construction and in com-
binations of parts more fully and particularly described and pointed out
hereinafter.
Referring to the accompanying drawings,
Figure 1 is a side elevation of a fountain pen embodying the present invention.
Figure 2, is a central longitudinal section through the feed and nozzle and a
portion of the barrel.
Figure 3, is a detail side elevation of the feed bar.
Figure 4, is a cross section taken on the line -)
-Figure 2.
Figure 5, is a cross section taken on the line y-Figure 2.
Figure 6 is a section taken on the line 3-Figure 2.
Figures 7 and 8 show side elevations of different forms of pen nozzles.
In the drawings A is the pen barrel having the pen nozzle screwed into the open
end thereof and a removable cap to fit on the pen nozzle and the outer end of the
barrel when removed from the pen nozzle.
The pen nozzle is of any ordinary or suitable construction with a cylindrical or
hollow interior passage.
c, is the feed bar preferably formed in one piece of hard rubber or other
suitable material and of a form and size to fit in the nozzle by friction. The outer
end of the bar is bifurcated longitudinally to receive and hold the gold pen, and
the feed tongues or fingers thus formed are properly shaped and arranged to form
the upper feed tongue e, resting on the upper surface of the pen and extending
down a suitable distance towards the point thereof, and the lower feed tongue f,
extending longitudinally of the under side of the pen.
Immediately in rear of the feed tongues the feed bar is in the form of a plug k,
to close the outer end of the nozzle.
In rear of this plug and within the nozzle the feed bar is provided with a trans-
verse opening 1, constituting an ink pocket. This opening is preferably arranged
centrally across the bar immediately in rear of the plug and the split of the bar
between the feed tongues is preferably continued through the plug into said ink
pocket so that the heel of the pen can extend to or be arranged in direct
communication with the ink pocket as clearly shown.
From the ends of said pocket to the inner end of the feed bar, said bar has
the longitudinal diametrically opposite ink ducts m, m, preferably formed by
flattening the opposite sides of the bar from the ink pocket to the inner end of
the bar.
h, is a longitudinal air passage extending longitudinally of the feed bar from the
inner end thereof into the ink pocket between its ends.

page_text: The inner faces of the feed tongues are provided with longitudinal grooves in
continuation of the central air duct through the feed bar. These grooves are
lettered i, j, in the drawings. The inner end of the nozzle can have an inward
extension n, if desired to enclose the inner end of the feed bar. This extension is
usually non-threaded and can be made as a complete cylinder as shown in Figure 8
or it can be divided as shown in Figure 7.
The great utility of such a feed as here disclosed is obvious. The air flows in
through the grooves in the feed tongues and through the central air duct, while
the ink flows down the flat sides of the bar and collects in the ink pocket and
from thence flows along the upper and lower sides of the pen. This ink pocket
keeps a plentiful supply of ink at the heel of the pen and prevents flooding.

Improvements in Fountain Pens.
I, CHARLES EATON BROWNING of 139 Huron Street, Toledo, Ohio, United
States of America, Manufacturer, 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 certain improvements in fountain pens.
The object of the invention is to provide a fountain pen exceedingly cheap,
simple and durable in construction and composed of a minimum number of parts,
and wherein a perfect and continual flow of ink will be produced without flooding
or dropping of ink.
The invention consists in certain novel features of construction and in com-
binations of parts more fully and particularly described and pointed out
hereinafter.
Referring to the drawings filed with my Provisional Specification,
Figure 1 is a side elevation of a fountain pen embodying the present invention.
Figure 2, is a central longitudinal section through the feed and nozzle and a
portion of the barrel.
Figure 3, is a detail side elevation of the feed bar.
Figure 4, is a cross section taken on the line a― -Figure 2.
Figure 5 is a cross section taken on the line y-Figure 2..
Figure 6 is a section taken on the line 3-Figure 2.
Figures 7 and 8 show side elevations of different forms of pen nozzles.
In the drawings A is the pen barrel having the pen nozzle screwed into the open
end thereof and a removable cap to fit on the pen nozzle and the outer end of the
barrel when removed from the pen nozzle.
The pen nozzle is of any ordinary or suitable construction with a cylindrical or
hollow interior passage.
c, is the feed bar preferably formed in one piece of hard rubber or other
suitable material and of a form and size to fit in the nozzle by friction. The outer
end of the bar is bifurcated longitudinally to receive and hold the gold pen, and
the feed tongues or fingers thus formed are properly shaped and arranged to form
the upper feed tongue e, resting on the upper surface of the pen and extending
down a suitable distance towards the point thereof, and the lower feed tongue f,
extending longitudinally of the under side of the pen.
Immediately in rear of the feed tongues the feed bar is in the form of a plug k,
to close the outer end of the nozzle. In rear of this plug and within the nozzle

page_text: the feed bar is provided with a transverse opening 1, constituting an ink pocket.
This opening is preferably arranged centrally across the bar immediately in rear
of the plug and the split of the bar between the feed tongues is preferably
continued through the plug into said ink pocket so that the heel of the pen can
extend to or be arranged in direct communication with the ink pocket as clearly
shown.
From the ends of said pocket to the inner end of the feed bar, said bar has
the longitudinal diametrically opposite ink ducts m, m, preferably formed by
flattening the opposite sides of the bar from the ink pocket to the inner end of
the bar.
h is a longitudinal air passage extending longitudinally of the feed bar from the
inner end thereof into the ink pocket between its ends.
The inner faces of the feed tongues are provided with longitudinal grooves in
continuation of the central air duct through the feed bar. These grooves are
lettered i, j, in the drawings. The inner end of the nozzle can have an inward
extension n, if desired to enclose the inner end of the feed bar. This extension is
usually non-threaded and can be made as a complete cylinder as shown in Figure 8
or it can be divided as shown in Figure 7.
The great utility of such a feed as here disclosed is obvious. The air flows
in through the grooves in the feed tongues and through the central air duct,
while the ink flows down the flat sides of the bar and collects in the ink
pocket and from thence flows along the upper and lower sides of the pen. This
ink pocket keeps a plentiful supply of ink at the heel of the pen and prevents
flooding.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is --
1. The herein described feed bar for fountain pens.
1
2. The feed bar made in one piece with the upper and lower feed tongues, the
central air duct, and longitudinal side ink passages.
3. The feed bar having the feed tongues and the plug portion at the inner ends
of said feed tongues, and air and ink passages.
4. The feed bar having the feed tongues, the flattened sides and the air passage,
substantially as described.
5. The feed bar having the feed tongues and the central air passage, the feed
tongues having the grooves in continuation of the central air passage.
6.. The feed bar made in one piece with the feed tongues, the plug portion, the
transverse ink pocket, the plug portion split through to the ink pocket, and air and
ink passages to the ink pocket.
7. The feed bar having the ink pocket.
8. The nozzle having the inward extension.
