MENTS IN ELASTIC PENS AND PENHOLDERS
Year: 1886

page_text: I ERNST MÖGEL of N° 8 Baum Strasse in the City of Dresden, Saxony,
Germany, Gentleman, do hereby declare the nature of my Invention for " IMPROVE-
MENTS IN ELASTIC PENS AND PENHOLDERS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following.
statement:-
.
My invention relates to improvements in elastic pens and penholders the object
of which is to enable persons whose calling or profession requires that they write
much and rapidly to effect the same without suffering from hand cramp or without
the hand becoming tired when the pen used is hard or unelastic. The hand of
such persons as aforesaid which have to write much and rapidly easily gets tired
whereas writing with a hard unelastic pen is very tedious and inconvenient for
persons writing a heavy hand. The fact of the hand getting accustomed to a
certain pen and it being very difficult to find others exactly suited to the writer
when the pen previously used is worn out, is well known so that a pen so con-
structed that it is calculated to overcome all these disadvantages would appear to
fill a long experienced want.
In order to carry my invention into effect I employ an extended or elongated
spirally coiled spring similar to the buffer springs employed in railway carriages or
I employ helical springs the one end of which said spirally coiled or helical spring
is attached to the stem or handle of the penholder proper whilst the forward or
opposite end is fixed to a holder or socket for receiving the pen or writing instru
ment which said holder is at its forward end of cylindrical form and is conically
enlarged to the rear, or towards the stem. The said stem is also of conical or
tapering form at its forward end and if desired can be provided with male screw
threads whereas the conical portion of the holder can be provided with corre-
sponding female threads so that if it is desired to dispense with the elastic action
of the said coiled or helical spring the stem can be screwed into the said holder or
the said conical forward end of the said stem can be inserted in the conical or cap
like rear end of the part holding or receiving the pen and be held therein by the
friction between the parts or in other suitable manner.

page_text: The manufacture of my said improved flexible pen can be simplified by cutting
out a suitable blank or piece of sheet metal one end of which is so formed that the
same constitutes the part into which the stem is inserted, the other end being
formed as holder for the pen or writing instrument.
If it is desired to employ my improved construction of pens in ordinary pen-
holders I make the rear part of the said spring of like form with the rear part
of ordinary pens or writing instruments or the rear part of the said spring can
be formed as customary with ordinary pens, the forward end be arranged as
pen whilst the intermediate part will be coiled to form the spring-If a helical
spring is employed the pen or writing instrument can be inserted between the
coils or windings of the same by alternately depressing or raising the said coils so
as to permit the insertion of the rear part of the pen between the said coils or
windings which is then firmly held by the said coils.
The elasticity of the spirally coiled' spring can be obviated by screwing a rod or
spindle running through the stem or holder the forward end of which said rod or
spindle is wedge shaped and can be pushed forward into the aforementioned
conically enlarged rear part of the writing instrument or the holder for the pen
so as to prevent all further action of the spring or instead of employing a rod or
spindle running through the axis of the stem an angular rod running in a suitable
slot in the stem can be employed. By pressing on the knob at the upper end of
this said angular or bell crank like rod the forward end is inserted in the rear end
of the holder for the pen or writing instrument and thus the action of the spring
paralysed.
Or instead of employing a coiled or, a helical spring the part for holding the pen
or writing instrument can be inserted in a cylindrical shell or tube provided with
a long spring as extension so that if said springy or flexible extension is pushed
forwards the same will give an elastic movement but only in a limited degree-
This said spring extension can be fixed to the stem or handle by means of suitable
rings.

Fig. 1 is an elevation and Fig. 2 a vertical section of one of my improved
holders for pens or other writing instruments-Fig. 3 represents a blank for
forming the holder for the pen or other writing instrument, the spirally coiled
spring and the conical recipient, for the stem or handle-Fig. 4 is the elevation and
Fig. 5 a vertical section of a modification in which the holder or clamp for the pen
or writing instrument and the spring are made of one piece the said spring having
a rear extension which can be inserted in holders such as are now in use.
Fig. 7 represents a blank for forming the device shown in Fig. 6 in which the
pen, spring and extension for insertion in an ordinary pen holder are made from
one and the same piece of metal-Fig. 8 is an elevation and Fig. 9 a section of a
helical spring for receiving the pen or writing instrument at the one end and the
stem or handle at the other.
Fig. 10 represents in part elevation and section a device for overcoming the
elasticity of the spring and Fig. 11 is a section of a device for effecting a like
purpose.
Fig. 12 represents the elevation-of-a-modification whereby the spiral coil-or the
helical spring is replaced by a long leaf spring attached to the stem or handle by
means of suitable rings and carrying at its forward end the holder or recipient for
the pen or writing instrument.
The coiled spring a (Fig. 1 and 2) is at its rear end provided with suitable
female screw threads b for receiving the male screw threads of the stem or holder c
and at its forward end with a holder, clamp or recipient d for the pen or writing
instrument the forward part of which said holder clamp or recipient d is of
cylindrical form and serves to receive the pen or writing instrument whereas the
rearmost part is conically enlarged to receive the forward conical end of the stem
of handle c.
In the position of the parts as represented in Fig. 2 the device is flexible in all
directions, Now if it is desired to dispense with the flexibility of the spring a it

page_text: is only necessary to screw the stem or handle forwards towards the pen when the
conical forward part of the said stem or handle will be inserted in the cone of
the holder clamp or recipient d when the parts will be rigidly connected with each
other.
It will be evident from the accompanying drawing that the flexibility of the
spirally coiled spring can be adjusted by screwing the stem or handle backwards or
forwards.
When the said stem or handle is fixed into the rear end of the holder or clamp
for the pen or writing instrument the coiled spring will be expanded-The manu-
facture of my improved device can be considerably simplified by making the holder
or clamp d, spring a and recipient b for the stem c from one piece of metal as
shown in Fig. 3-The forward end of the blank is bent up to form the clamp or
holder for the pen or writing instrument the main part of the blank bent or coiled
so as to form the spiral coiled spring a whilst the rear end of the said blank is
bent up to form the recipient 6 for the stem or handle c.
Instead of employing the recipient d the rear end of the blank can receive the
form of the rear part of an ordinary pen so that the same can be inserted in an
ordinary pen holder as represented in the Fig. 4 and 5-Or as represented in
Fig. 6 and 7 the spring a, rear end 7 for insertion in ordinary pen holders and the
pen can be made from one piece of metal as shown by the blank Fig. 7 and the
finished spring or elastic pen Fig. 6-As aforementioned a helical spring a¹ can be
employed instead of the spirally coiled spring represented in the preceeding
Figures. In this case the rear end of the pen fis inserted between the coils of
the helical spring a' by alternately raising or depressing the coils of the said
helical spring and the stem handle or holder c is screwed into the said helical
spring until the requisite elasticity or rigidity is attained.
If the stem or handle c is screwed so far forward that the same comes beneath
the rear part of the pen ƒ a rigid connection will be made-The elasticity of the
spirally coiled spring a (Fig. 1 to 7) can be overcome and the entire device made
rigid by employing one of the arrangements represented in Fig. 10 and 11 or mere
modifications of the same.
In the arrangement as represented in Fig. 10 the stem or handle c is supposed to
be firmly connected to the rear end of the spring a-1
-Now in order to overcome
the elasticity of the said spring a rod or spindle g provided at its forward end
with a suitable cone gl can be screwed forward into the conical opening of the
clamp holder & so that the spring is placed out of action or instead of the rod or
spindle g an angular rod or slide rod / Fig. 11 can be used which is also provided
with a suitable cone g¹ in such manner that when the said angular or slide rod is
pushed forwards by means of the forefinger or thumb the cone g¹ will be pushed
into the rear part of the holder for the pen or writing instrument and the spring
rendered inactive.
A modified form of pen is represented in Fig. 12 in which the rear portion of the
pen is extended so as to form a long leaf spring which can be attached to the .
stem or handle c by means of suitable rings r. If the spring is pushed forward
the pen will be flexible to a certain extent and if the same be drawn back the said
pen will be rigidly connected to the stem or holder.
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
1. The arrangement and application of a spirally coiled spring a to a stem
handle or holder c for rendering the pen or writing instrument flexible in all
directions and the device for rendering the said spring inoperative by screwing
the stem or handle c into the cone d of the holder or clamp for the pen f,
(Fig. 1, 2, 3) or by means of the rod or spindle g (Fig. 10) of the angularly bent
sliding rod h (Fig. 11) and the cone g or g¹ substantially as set forth in the
foregoing specification and shown in the accompanying drawings.

page_text: 2. The application and employment of the coiled spring a, which is so provided
with a rearward extension that the same can be used in ordinary holders sub-
stantially as described in the foregoing specification and shown in Fig. 4 and 5 of
the accompanying drawings.
3. The combination of the spring a, pen f and extension / said parts being made
from one piece of metal substantially as set forth in the foregoing specification
and shown in Figs. 6 and 7 of the accompanying drawings.
4. The application of the helical spring a for holding the pen f by inserting the
same between the alternately depressed coils and also for receiving the stem handle
or holder c substantially as set forth in the foregoing specification and shown in
Figs. 8 and 9 of the accompanying drawings.
5. The arrangement of the cylindrical holder or clamp k with long leaf spring
which latter is attached to the holder c by means of the rings substantially as
set forth in the foregoing specification and shown in Figure 12 of the accompanying
drawings.
