HANS WILHELM CASPERSEN, of the Town & County of the Town of Newcastle-
on-Tyne. "IMPROVEMENTS IN METALLIC PENS OR NIBS AND IN HOLDERS FOR THE
SAME, WHICH LATTER ARE ALSO SUITABLE FOR ORDINARY NIBS OR PENS." A
communication from abroad by Niels Henrik Holst, of Aarhuus, in the Kingdom of
Denmark.
This Invention relates to a peculiar construction of metallic pens and holders for
the same, which holders are also applicable for use with ordinary metallic nibs or
pens.
According to the first part of this Invention it is proposed to make that portion
of a metallic nib or pen which is intended to be inserted into the holder in the form
(in transverse section) of two planes meeting each other in the longitudinal centre
line of the pen, with or without a small rounding or flattening at the ridge or line
of junction of the said planes.
The remaining portion of the nib or pen may be of different forms to suit the
particular requirements for which the pen is intended.
The holder for the improved form of pen is to be inade with a prismatic shaft or
socket, that is to say, that portion of the holder which is grasped by the fingers

page_text: when writing should have a polygonal transverse section with, say, six or more or
less flat sides corresponding in their angles to the angle of the two planes of the
pen. In addition to the aforesaid flat sides on the penholder one portion thereof is
inade of the usual semicircular or rounded section, so that the same holder will
accomodate either the improved pen or a pen of the ordinary make; or the holder
can be made to hold the angular pen alone, or be adapted solely for ordinary pens.
The upper part of the penholder may be made of round wood or of any other
suitable form & material.
By the adoption of the herein-before described pen and prismatic-shaped holders
the pen is more firmly held in its holder, whilst at the same time the holder can be
more steadily and firmly retained between the fingers, thereby greatly facilitating
the operation of writing and improving the writing itself.

HANS WILHELM CASPERSEN, of the Town and County of the Town of Newcastle-
on-Tyne. "IMPROVEMENTS IN METALLIC PENS OR NIBS & IN HOLDERS FOR THE
SAME, WHICH LATTER ARE ALSO SUITABLE FOR ORDINARY NIBS OR PENS."
communication from abroad by Niels Henrik Holst, of Aärhuus, in the Kingdom of
Denmark.
This Invention relates to a peculiar construction and arrangement of metallic
pens and holders for the same, which holders may be used either in conjunction or
not with ordinary metallic nibs or pens, and has for its object.-
First. To give that portion of a metallic nib or pen which is intended to be inserted
into the holder an angular transverse section with or without a small rounding or
flattening at the top of the angle, as herein-after described.
Second. To give that portion of a penholder which is grasped by the fingers
when writing a prismatic or polygonal form, thereby affording a firmer hold of the
pen, and an improvement in the writing is obtained.
In carrying out the first part of this Invention it is proposed to make the part of
the nib which is secured into the holder in the form of two planes meeting each
other under an angle in the longitudinal centre line of the pen with or without a
small flattening or rounding at the junction of the two planes.
The remaining portion of the nib or pen may be made of different forms to suit
the particular requirements for which the pen is intended.
According to the second part of the said Invention, which relates to the holders
to be used with the herein-before described metallic nib or pen or with the ordinary
existing pens, I make the holder of a prismatic form, that is to say, with a polygonal
section of, say, six or more or less flat sides. The end of the holder in which the
nib or pen is to bo fixed is formed so that the above-described or a common pen or
nib may be inserted, or either of them.
The upper part of the holder may be made of wood or other suitable material,
& be of a prismatic or cylindrical or any other desired form.
And in order that the said Invention may be fully understood, I shall now pro-
ceed more particularly to describe the same, & for that purpose shall refer to the
several Figures on the explanatory Sheet of Drawings hereunto annexed, the same
letters of reference indicating corresponding parts in all the Figures.
Figure 1 is a view of the under side of the pen and holder as intended to be
used.
Fig. 2 is a section through the said improved holder & the prismatic or poly-
gonal metal socket for the pen.
« is the shank or upper part of the holder, which can be made of wood or other
suitable material; b, the pen (with angular parts f & flattened top g) shown
applied; c, the metal tube which fits on to the holder a, & is made of a polygonal
or prismatic section of any desired number of flat sides, six being shown in the
Drawing, & receives the pen b. If desired, this tube c can be cut half through at
a suitable distance from the end in which the pen is inserted, and be compressed in
the form shown at d, Fig. 1, and in section at Fig. 3, the projecting edges d', d¹,
pressing the pen up tightly against the flat sides e, e, & thus effectually securing the
same. Or the said tube c can be made so as to suit the holding of the pen in any
other convenient manner, thereby adapting the improved style of penholder to
ordinary pens as well as to the improved angle pens.
Figures 4 & 5 show another mode of constructing the holder, which consists of a
prismatic or circular shank a, at the end of which is fixed a prismatic metallic
tube c of, say, six (more or less) sides, as shown in section at Fig. 4.
Instead of bending this tube c at the end which receives the nib or pen, as in the

page_text: before-described arrangement, the same contour or shape is kept throughout the
tube, and the shank, which is turned or otherwise made cylindrical at that part
where it enters the tube c, can be carried nearly through, and is made to fit properly
over the said shank a, see Fig. 4, a very slight opening being left for inserting the
pens (which, when inserted, firmly secure these parts of the pen and holder in their
place), and may be of the ordinary kind or the angle pens herein described.
Figures 6, 7, 8, 9, 10, & 11 are diagrams illustrating the construction of the
improved pens which are made at that part fintended to be inserted into the holder
of two planes (in transverse section) meeting each other at the angle in the longi-
tudinal centre line of the pen, the ridge or line of junction of the said planes
being formed either with a small flattening or rounding, or carried to a point, as
shown in section in the diagram, Figs. 6, 8, 9, & 10.
The remaining portion of the nib or pen may be of the ordinary class, of different
forms to suit the particular requirements for which the same is intended.
It will be obvious that by the adoption of the improved angle pens and prismatic-
shaped holders herein-before described the pen can be more firmly grasped by the
hand when writing, and also that the nib or pen will be more securely held in its
place in the holder, whilst at the same time the operation of writing is greatly
facilitated and the writing itself improved.
Having now described and particularly ascertained the nature of the said Inven-
tion, & the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to bo novel & original, and
therefore claim as the Invention secured to me by the herein-before in part
recited Letters Patent is,-
First. The constructing that portion of a nib or pen intended to be inserted into
the holder of an angular transverse section with or without a slight flattening or
rounding at the top of the angle, as herein-before described, and illustrated by the
Drawings.
Second. The combination with a prismatic or polygonal or other shaped penholder
of a metallic tube of a prismatic or polygonal section bent or not at the end to
receive the pen or nib, substantially in the manner herein-before described, & shown
in the Drawings.
Third. The application & use of the before-described penholder to & with nibs or
pens of the ordinary construction, as herein described.
In witness whereof, I, the said Hans Wilhelm Caspersen, have hereunto set
my hand & seal, this Twenty-fifth day of January, in the year of our Lord
One thousand eight hundred and seventy-nine.
