Swain Champness at the Office of the Commissioners of Patents, with
their Petition, on the 5th August 1858.
We, WALKER MOSELEY, of Nos. 17 and 18, New Street, Covent Garden, in
the County of Middlesex, Gentleman, and WILLIAM SWAIN CHAMPNESS, of
Clapham, in the County of Surrey, Gentleman, do hereby declare the nature
of the said Invention for "AN IMPROVED SELF-FILLING RESERVOIR PENHOLDER,"
to be as follows:-
The object of this Invention is the construction of a penholder which will
charge itself with a considerable quantity of ink, and also supply the same to
the pen in small quantities as may be required.
It consists of a tube of hard india-rubber, metal, glass, or other suitable
material, terminating at the end, where the pen is fixed, with a fine hole, to the
other end is attached a flexible chamber made of india-rubber or of other
suitable material,, either spherical, tubular, or any other shape. Its action is
as follows:-The air is exhausted from the flexible chamber by compressure
thereof, the point is then dipped into the ink, and the flexible chamber is
released, when the ink at once rises into the tube. The ink is supplied to the
pen as needed by compressing the flexible chamber, whereby the ink is ejected
through the fine hole into the pen, which may be of any description now in
use. To regulate the supply of ink from the reservoir to the point of the pen,
there is attached to the holder proper a sliding channel or regulator of metal
or other material, the end of which is curved and bears upon the inner surface
of the pen, the intention of which is to ink the point of the pen, when dry
from disuse, by means of its sliding movement, and also as a cup to cause the
pen to contain a larger quantity of ink than is retained after the customary dip.
There is also a long thin wire terminating with a small conical or pin's head,

page_text: and is used as a ramrod to precipitate the ink from the narrow part of the
tube, where it otherwise would remain by reason of the greater capillary
attraction, so that by repeating the filling process as before directed two or
three times, and at each time holding the reservoir perpendicular with the
narrow end uppermost, by means of the ramrod, the whole of the tube and
flexible chamber may be filled with ink, and when the ramrod is attached
loosely to the regulator, and the stem inserted in the reservoir, the conical head
may be partly pushed into the fine hole of the small supply tube, and thereby
form a stopper to prevent the ink clogging in the small tube when not in use.
This is done by sliding the regulator against the reservoir tube, and the reverse
when the pen is in use.
If it be required to protect the flexible chamber from accidental pressure or
to render it portable for the pocket, without a loose case, it may be readily
effected by encircling the same with thin metal and continuing it along the
body of the holder, either as shown at Figures 8 and 9, or by means of a short
screw-cut neck which works upon the hollow plug, also screw cut, whereby
we obtain the compressure of the flexible chamber by turning the metal
covering upon the screwed hollow plug. The flexible chamber in the form of
a tube may be extended the whole length of the outside tube and the com-
pressure be obtained by twisting it or by passing over its outside surface and
between that and the inner surface of the outer tube a ball or any other sliding
or rolling appliance.
