Complete Specification Accepted, 18th May, 1889
I, JOHN ISIDORE HARRIS of 8 Victoria Buildings Queen Street, Melbourne in the
Colony of Victoria, Gentleman, do hereby declare the nature of this invention to be as
follows:-
"This invention of improvements in and relating to pens and holders therefor has
for its object to facilitate the removal of an old or useless nib from a holder and the
substitution of another fresh nib therefor, thus obviating the necessity for employing
the inconvenient system at present in use.
My invention consists essentially in providing a hollow penholder constructed to
contain a number of nibs and fitted with a suitable device which may be operated by
pressing a conveniently arranged spring whereby the old nib may be ejected from the
holder and a fresh one substituted therefor. These nibs are arranged one behind the
other in the holder and each one is provided with a recess, formed by a thin web of
any suitable material, into which the point of the nib next behind it is arranged to
enter and is thereby preserved from the corrosive action of the ink.
When all the nibs in the holder are exhausted a fresh supply may be inserted by
operating the spring device above mentioned as will be well understood by persons
skilled in the art to which my invention relates.

page_text: I, JOHN ISIDORE HARRIS, of 8 Victoria Buildings, Queen Street, Melbourne, in the
Colony of Victoria, gentleman, 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 of improvements in pen-holders- has been devised for the purpose of
providing means whereby the substitution of a new nib for an old or useless one will
be rendered simpler and less objectionable than heretofore.
The essential feature of my invention is the combination with a pen-holder adapted
to contain a number of nibs placed one behind the other of a suitable device whereby
the said nibs may be pushed along the holder so that the end one will be forced out
and the next one will be substituted therefor, and when that is worn out it also will be
pushed out and the next one substituted for it.
Referring to the accompanying drawing,
Figure 1 represents a side elevation drawn to an enlarged scale, of so much of a
pen-holder constructed according to my invention as is necessary to illustrate it.
Figure 2 is a transverse section on line a x figure 1 and
Figure 3 is a similar view to figure 1 but with the outer casing of the pen-holder
removed in order to better illustrate the construction and arrangement of said
holder.
In constructing a pen-holder according to my invention I provide a suitable tube A
adapted to receive a small screw threaded rod B. This rod extends from end to end
of the tube A and has at its upper end a small milled projection or knob & whereby it
may be rotated whilst on its other end is secured a collar b¹ whereby said rod is held
in position within the tube A. A small carrier C is arranged to slide longitudinally
in a slot a formed in the tube A and serves to convey the nibs along the tube.
It is screwthreaded to receive the rod B whereby it is operated. In practice five
or six nibs are placed within the groove or channel a¹ of the tube A (the carrier C
being drawn back out of the way in the recess a³) so that in order to change a
nib it is only necessary to rotate the milled projection in the proper direction and
to a sufficient degree to cause the carrier C to push against the rearmost nib in
the holder and eject the lowermost one substituting the next one therefor. In
order to protect my improved pen-holder from injury 1 enclose it in an outer
casing or cover D.and I sometimes secure a protecting piece E at the lower end
which by pressing closely against the underside of the nib in use prevents the ink
from interfering with the working of the operating screw threaded rod B. The
nibs may be of ordinary construction as shewn, or each may have at its butt end
a recess to receive and protect the point of the nib behind it, but to such construction
of the nibs I make no claim.

page_text: 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 :
First. My improvements in pen holders consisting in the combination with a
tubular pen-holder adapted to contain a number of nibs placed one behind and end on
to each other of means, such for instance as those herein described, whereby said nibs
may be carried along said tube in order that a new nib may be substituted for the one
previously in use substantially as herein specified and as illustrated in the accom-
panying drawing.
Second. The combination with a screw threaded rod, of a carrier such as C whereby
the nibs contained in a suitable groove in a pen-holder may be propelled along said
groove substantially as and for the purpose specified and as illustrated in the accom-
panying drawing.
Third. The combination of parts constituting my improved pen-holder all constructed
arranged and operating substantially as and for the purpose specified and as illustrated
in the accompanying drawing.
