MENTS IN WELL PENHOLDERS
Year: 1884

page_text: I FREDERICK BARON MICHELL of 29 Kirkgate Wakefield in the County of
Yorkshire, Watchmaker do hereby declare the nature of my invention for IMPROVE-
MENTS IN WELL PENHOLDERS to be as follows:-
An India rubber bag, completely closed in every part, excepting that nearest the
pen, where it snaps on a small tube, is enclosed in a tube of metal, or any other
suitable material,
The latter is cut away in the middle, in such a manner as best to allow the
rubber to be compressed between the fingers and thumb of the user, so as to create
a vacuum in the rubber bag. When the pen is dipped in the ink, and the rubber
is thus compressed, the ink is driven up into the bag, through the small tube, by
the pressure of the air on the ink's surface. It is not, therefore, an automatic
supplying penholder, but the ink is caused to flow by the pressure of the thumb on
the rubber bag in the the natural motion of writing.
The small tube for supplying the pen may be placed either at the back or front
thereof, but by preference I place it at the back, to make a more easy arrangement
for holding the pen.
To avoid capillary attraction holding the ink between the pen and the tube, my
tube does not run in a parallel line with the pen up to the part where it bends
down to supply it with ink, but is very considerably curved from leaving the large
tube until it unites with the pen, for the reason stated above.
For the insertion of the pen, the under part of the large tube, at the lower end,
is cut away; so that two narrow rings confine the pen in its place.
A short tube, to protect the rubber when out of use, slides over the long one:
and a cover, fitting on either end, may be supplied when required for pocket use.
No 1 Drawing Is Penholder with pen fixed, both sides of which, being alike,
fairly represents surface view.
No 2 Is section thereof.
A Is the curved small tube for supplying ink.
B & B 1 Are fixed rings to confine the pen.
Is exposed part of rubber bag to compress for filling, and supplying.
D Is slide to protect rubber bag when out of use.
F Is tube of metal or other suitable material.
G Dotted lines to indicate cover for the protection of pen when out of use or
carried in the pocket.

SPECIFICATION,
I FREDERICK BARON MICHELL of 29 Kirkgate Wakefield in the county of
York, Watchmaker do hereby declare the nature of my invention for IMPROVE-
MENTS IN WELL PENHOLDERS, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
The purpose of my invention is to form a Penholder that can be instantly
Bupplied with a well, or fountain of ink, which can be caused to flow thence to the
pen in use by the natural pressure of the users thumb and finger during the process
of writing This is effectuated in the following manner A rubber bag, closing on
a small tube near the bottom of the penholder, is enclosed in a tube of metal, or
other suitable material. From the middle of the said outside tube, two sections are
cut away, so as best to allow the thumb and finger, or thumbs and fingers, to
compress the rubber between then. Thus expelling the air from the tube so
compressed while it is in the ink, and when the pressure is withdrawn, the air,
pressing on the surface of the ink, drives it up into the vacuum when the well or
fountain is ready for use. In writing, the thumb and finger press on the said
rubber bag; lightly during the formation of the upward, or hair lines, and more
heavily in returning; when the ink flows in proportion to the pressure: and is
withdrawn from the pen on its ceasing.
It is a distinguishing principle of the most essential importance in my invention,
that in no case should the upper part of the bag extend more than a quarter of an
inch, or so, beyond the openings to admit of its compression between the thumb
and finger as its greater extension causes the air to become too rarefied to make
the ink flow with such an easy pressure as is necessary in easy writing. If, however,
it should be found requisite to take in more ink than is induced to flow up by the
compression provided, a like contrivance, with a piece left between to strengthen
the holder, may be made further up: when it will be found necessary to compress
the upper part of the bag first in driving out the air, and both hands will be
employed in filling.
The small tube, connecting the well with the pen, which may be placed either at
the back or front of the latter, is curved, to prevent capillary attraction retaining
the ink between them during writing. Covers may be provided to protect the pen
and rubber when out of use or in the pocket.
The pen may be inserted between the small tube at the bottom and the outside
tube, or by means of an extra tube, ring, or rings.
A pencil may be supplied at the opposite end to the pen if preferred.

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is performed I declare that what
I claim is
1st A method of filling through creating a vacuum by expelling the air as above
described.
2 Supplying the ink by pressing on the rubber bag with the finger & thumb
during writing.
3 The curving the small tube, to prevent capillary attraction retaining the ink
as described above.
4 The closing the bag immediately above the opening or openings in the outside
tube for the former's compression.
5 Covers to protect the pen & rubber.
6 The use of pencil at the opposite end to the pen.
