Improvements in Stylographic Fountain Pens.
I, ALONZO TOWNSEND CROSS of 128 Hanover Street, Providence, Rhode
Island, 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 :-
The object of my invention is to provide a stylographic fountain pen, which will
be simple in construction, and not liable to get out of order, and which may be
set in operation with certainty when the ink has become dried at the delivering
point. And my invention consists in the employment of a loosely connected
gravitating rod and ink-delivering pin, with a point-section tip provided with an
enlarged hore and an ink delivering bore of small diameter, the gravitating rod
and pin having an extended range of movement, whereby the up and down shaking
of the pen will cause the withdrawal of the delivering pin, from the delivering bore
of the tip of the point-section, to the enlarged bore of the same, and the dried ink
will be expelled at the downward movement of the delivering pin.
In the accompanying drawing:-
Fig. 1, represents a longitudinal section of a stylographic fountain pen provided
with my improvement, showing the ink-delivering pin at its normal position.
Fig. 2, represents a longitudinal section of the pen, showing the ink delivering
pin at its highest elevation in the bore of the point section.
Fig. 3, represents an enlarged longitudinal section of the outer shell of the
point-section, taken at right angles to the position shown in Fig. 1.
Fig. 4, represents an enlarged section of the same taken in the same plane as
that of Fig. 1.
Fig. 5, represents an enlarged end view of the inner tube of the point-section.
Fig. 6, represents a side view of the same.
In the accompanying drawings, A represents the barrel of the fountain pen,
and B a permanently secured plug at the upper end of the same, the said plug
being provided with the downwardly extending tube a, having the slots b, b, at its
opposite sides. To the lower end of the gravitating rod C, is secured the ink
delivering pin e, and the upper end of the gravitating rod C, is loosely held in the
bore of the tube a, and secured therein by means of the cross pin c, whereby the
gravitating rod and pin e, is made capable of an extended up and down movement.
The point section D, of the pen, is preferably made in two parts f and g,
the tubular tip f, being held within the outer shell g, of the point-section. The
bore of the said tubular tip is made conical at its lower end, leaving a comparatively

page_text: short delivering bore h, which loosely surrounds the ink-delivering pin e, of the
gravitating rod C. The slots b, b, of the tube a, are so formed, as to allow a
sufficient up and down movement of the gravitating rod C, to carry the ink-
delivering pin e, entirely out of the delivering bore h, as shown in Fig. 2, when
the pen is being shaken up and down to clear the bore h, from a deposit of dried
ink, the pin e, operating as a plunger to force the said deposit outward, upon
the downward movement of the pin e, from the enlarged portion i, of the bore of
the tip.
The air is admitted to the ink chamber E, through an air passage j, formed
partly in the outer side of the wall of the tubular tip f, and partly at the inner
side of the wall of the outer shell g, of the point-section, as illustrated in Figs. 3
to 6, inclusive.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
In a stylographic fountain pen, the combination of the barrel, and the point
section provided with the enlarged bore, the contracted ink-delivering bore, and
the passage for conducting the air upward into the ink chamber, with the loosely
connected gravitating rod and ink-delivering pin, adapted for extended up and
down shaking movement, within the barrel, whereby the ink delivering pin will be
caused to pass into and out of the ink delivering bore, substantially as described.
Dated this Sixteenth day of June A.D. 1896.
