IMPROVEMENTS IN RESERVOIR PENHOLDERS
Year: 1886

page_text: We MAXIMILIAN RESCHKE and IGNAZ LEUTNER, of Halle on the Saale in the
Empire of Germany, Pen Manufacturers, do hereby declare the nature of our
Invention for "IMPROVEMENTS IN RESERVOIR PENHOLDERS," 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 improvements in reservoir penholders in which the ink
reservoir is located in the interior of the holder and is composed of a closed tube of
india-rubber or other appropriate watertight elastic material.
Fig. 1 is a broken longitudinal section of the holder with the elastic reservoir in
elevation on an enlarged scale. Fig. 2 is a section of the upper part of the holder
with the knob screwed out and the elastic reservoir extended and put under
torsion. Fig. 3 is a section of the clamp for holding the pen or writing instrument.
said clamp being inserted in the forward end of the holder. Fig. 4 is an elevation
of Fig. 3. Fig. 5 is a longitudinal section of the complete holder.
The upper knob a is securely connected to the screw b which runs through a
suitably flanged nut c attached to the exterior tube d of the holder.
The lower end of the screw b is provided with two suitable collars or flanges
between which the same is annularly recessed at e so that the elastic reservoir f
can be securely attached to the same by means of an elastic ring or in other
suitable manner.
The reservoir f consists of a piece of india-rubber tubing which is as aforesaid
attached securely to the forward end of the screw b.
is
The forward end of the said reservoir f is attached to a stopper h provided
with the flange i and annularly recessed rear end g.. This said stopper
inserted in the forward end of the main tube d and protrudes a suitable distance
into the interior of the same so as to form a perfect closure and also serve to
receive the forward end of the elastic reservoir f which is securely fixed to the
annularly recessed rear part g of the said stopper h whilst the inward movement of
the stopper is hindered by the flange i which is of like diameter with and runs
perfectly flush with the main tube or cylinder d.

page_text: This said stopper is furthermore provided with screw threads to receive a
suitable cap for protecting the pen or writing instrument and forward of these
said screw threads k with a plain annular surface 1, and is further provided with a
boring of three various diameters o, n, m.
The boring o which can be riemered out somewhat at its rear end is in com-
munication with the elastic reservoir and when the pen clamp is inserted also with
the boring of the same as will be described later on in this specification.
The boring n is made somewhat conical to receive the conical end p of the pen
clamp whilst the boring m into which the part q of the said clamp is inserted is
made of cylindrical form.
The pen clamp is preferably made of vulcanite, ebonite, or other similar material
and is at its rear end turned off or so formed that the conical part p is obtained
which as aforementioned is fixed or inserted into the conical boring n of the
stopper h whilst the tongue x of the clamp serves to hold the part q securely in the
cylindrical part m of the stopper.
of
The pen clamp or the part employed for holding the pen or writing instrument
is provided with a central boring v corresponding with the boring o of the stopper h
which said boring vis in communication with a short canal or boring w which
connects at the one end with the boring or canal whilst the other open end is
formed in the inclined surface 7, 8, at the foremost end of the clamp and beneath
the pen or writing instrument which is inserted between the outer surface
the clamp and the inner surface of the cylindrical boring m of the stopper, in a
position opposite the spring tongue x hereinafter referred to.
A tapered alot t, u, is made at the rear of the boring so as to form a spring
tongue which serves to hold the clamp q securely in the boring m of the
stopper h.
D is a small pin or stud provided at its inner end with a suitable head or flange y
and which passes freely through an ebonite, vulcanite or other bushing z, whilst
the head or flanged end is in contact with the elastic reservoir f so that if the
reservoir is provided with ink or writing fluid and pressure is exerted on the outer
end of the said pin or stud D. the elastic reservoir will be compressed and ink or
writing fluid forced to flow into the pen, or other writing instrument.
In order to fill the reservoir with ink or writing fluid the knob or button a,
is screwed out and as the space in the interior of the main tube d, is longer than
the said reservoir the elastic tubular reservoir f, is not only extended but so
twisted that the air contained in the said reservoir is expelled. This position of
the knob or button a, and the elastic reservoir f, is represented in Fig. 2 of the
accompanying drawinga. こ
If the pen or writing instrument is now inserted into writing fluid until the
canal or boring w, is covered by the said writing fluid whereupon the knob or
button a, is screwed back again into contact with the flanged nut c, so much
suction will be created that the reservoir will be entirely filled with writing fluid,
which after withdrawing the pen and penholder from the fluid in the inkstand
or other receptacle will be retained in the reservoir f, by the pressure of the
atmospheric air and will only then be caused to flow from the boring w, when
pressure is exerted on the pin or stud D, the capacity of the reservoir thus
decreased and the writing fluid caused to pass from the same through the
borings o, .v, w, to the pen or writing instrument. The arrangement of the
boring w, at an incline to the boring v, prevents too large a quantity of ink
from flowing into the pen.
When not in use a suitable cap can be screwed over the writing instrument to
prevent the same from being injured for which said purpose the screw threads k,
on the stopper h, are employed. It will from the foregoing specification be evident
to all connected with this branch of industry that the various parts of my improved
reservoir penholder can be modified in various ways without in any way departing
from the tenor of my invention.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :
1. In reservoir penholders, the combination of the elastic reservoir f with the
screw bin such manner that by screwing the said screw b outwards the said
reservoir will be simultaneously elongated and twisted together substantially as
and for the purpose set forth in the foregoing specification and represented in the
accompanying drawings.
2. The arrangement, application and employment of the boring w, said boring
running at an incline to the boring of the pen clamp and the arrangement of
the slot t, u, in such manner that a spring tongue x, is formed, substantially
as described in the foregoing specification and shown in the accompanying
drawings.
3. The pressure pin or stud D with the flange y, and the bushing 2, for exercising
pressure on the elastic reservoir f, so as to compel the ink or writing fluid con-
tained in the same to flow to the pen or writing instrument substantially as
described in the foregoing specification and represented in the accompanying
drawings.
