PROVISIONAL SPECIFICATION.
Improved Attachment for Pen Holders for Limiting and Regulating
the Depth of Dipping the Pens.
I FRIEDRICH TREIER, of 37 Mariahilfer Strasse, in the City of Vienna, Empire
of Austria, Director of a Machine Factory, do hereby declare the nature of my
invention for "IMPROVED ATTACHMENT FOR PEN HOLDERS FOR LIMITING AND
REGULATING THE DEPTH OF DIPPING THE PENS" to be as follows
This invention relates to an attachment for pen holders for limiting and
regulating the depth of dipping the pen into inkstands when writing, and is
adjustable and adapted for all kinds of pen holders. Its object is to avoid the
troubles and inconveniences arising from the dipping of the pen too deep into the
ink, whereby the nib becomes dirty by entering the sediment in the inkstand, or
striking the bottom of same; by employing the attachment it is impossible that on
withdrawal of the pen the ink splashes over the desk or papers by reason of the
too deep immersion of the pen.
This device or attachment consists essentially of a sleeve with one or more
cross bars or fingers, but preferably two, which protrude from the same in such
manner that when the sleeve is pushed on the holder and fixed sufficiently near the
pen, the depth of the dip is limited by the cross bars coming in contact with the
edges or neck of the inkstand.
In order that the device can be arranged so as to correspond with the different
heights or sizes of inkstands, or with the varying levels of the ink, the sleeve can
be moved up or down the holder into any desired position, either by means of a
clamping screw, or by a slit being made along the whole sleeve so that it is held
or secured on the holder by its self-springing properties. This latter arrange-
ment can be carried out in the cheapest and simplest possible manner by cutting,
punching or stamping from a sheet of metal a rectangular plate of the size
required with two linear incisions or slots near one end, and bending the wider part
of the plate to form the sleeve with a slit along its whole length, while the smaller
strips remain straight and form the two cross bars or fingers. If the incisions
are made in the form of a wedge or triangle, the sleeve will have a better
appearance.
In order to increase the action of the sleeve as a spring, tongues, lugs or fingers
can be cut or stamped out of such sleeve before being bent in the form of the
sleeve, such tongues or fingers being only attached to the metal of the plate on
one side, whereas the fore ends are bent around similarly to the sleeve itself but
preferably to a diameter somewhat smaller than that of the sleeve. Or the sleeve
can be made so that it can be inserted in the aperture of the holder which receives
the pen, and can, at the same time, serve to hold the pen; or such sleeve can be
substituted by a pin adjustable in the holder, and adapted to secure the dipping
attachment to the same.

Improved Attachment for Pen Holders for Limiting and Regulating
the Depth of Dipping the Pens,
I, FRIEDRICH TREIER, of 37 Mariahilferstrasse, Vienna, in the Empire of
Austria, Machine Factory Director, 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 relates to an improved attachment for pen holders for limiting
and regulating the depth of dipping the pen into inkstands when writing, such
attachment being adjustable and adapted for all kinds of pen holders. Its object
is to avoid the annoyances arising from the too deep immersion of the pen into the
ink and the consequent dirtying of the nib by entering the sediment in the inkstand,
the striking of the nib on the bottom of same, and the splashing of the ink over the
desk or papers afterwithdrawal of the pen by reason of the said too deep
immersion.
I will now describe my invention with reference to the accompanying drawing in
which
Fig. 1 shows a pen holder provided with the improved attachment, the inkstand
being shown in section.
Fig. 2 is the front view of a plane piece of stamped sheet-metal for forming the
sleeve.
Fig. 3 is a plan view showing same bent so as to form the sleeve, the fingers t
remaining straight.
Fig. 4 is an elevation of the sleeve.
Fig. 5 is the front view of a plane piece of sheet metal provided with tongues cut
or stamped out.
Fig. 6 is a plan of same after the sleeve has been formed.
Fig. 7 an elevation of the sleeve.
The device or attachment consists of a sleeve h with one or more cross bars or
fingers t protruding from same in such manner that when the sleeve has been put
on the pen-holder and fixed sufficiently near the nib, as shewn in Fig. 1, the
depth of the dip is limited by the fingers t coming in contact with the edges or neck
of the inkstand.
In order that the device can be made to correspond with the different sizes of
iukstands and the varying depths of ink in same, the sleeve his adjustable by means
of the slit in same which enables it to be held or attached to the pen holder by
itself-springing properties.
This device can be made in the cheapest and simplest possible manner by cutting,
punching, or stamping from a sheet of metal a rectangular plate m (Fig. 2) of the
size required, with two linear incisions or slits n near one end and then bending
the wider part of the plate to form the sleeve h with slit along its whole length,
while the smaller strips remain straight and form the cross-bars or fingers t as
shown in Fig. 3.
If triangular or wedge-formed incisions are made in the plate instead of the
linear slits n, the sleeve has a lighter and better appearance.
In order to increase the springing-properties of the sleeve lugs, tongues or
fingers (Fig. 5) may be cut or stamped out of the rectangular plate m before
being bent to form the sleeve, such tongues or fingers being only attached to the
metal on one side, whereas their free ends are bent similarly to, but preferably to a
diameter less than the sleeve itself.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(
1. An improved attachment for pen holders consisting of an adjustable sleeve (h)

page_text: formed by bending a rectangular plate of sheet metal and having one or more arms
or fingers (t) for limiting the depth of immersion of the pen into the inkstand,
substantially as described and shown in the drawings.
2. A modification of the attachment as described in Claim 1 according to which
lugs or tongues (2) are cut or stamped out of the rectangular plate (m) before
bending, for giving the sleeve the more effectual qualities of a spring substantially
as described and shown in the drawing.
