CARL KESSELER, of 63, Mohrenstrasse, Berlin, W., in the Empire of Germany.
"IMPROVEMENTS IN STYLES." A communication from William Sachs, Secretary
to the Genoral Post Office, Berlin, of Berlin, in the Empire of Germany.
The improvements consists in the combination in a style of an ink pen and style
or impressing instrument proper, for the purpose of writing or making devices to
be traced in ink on paper and at the same time impressing one or more copies
thereof by the use of manifold writers as at present, or other equivalent
arrangement.
The style has a sharp groved point with an inner cavity for holding ink, and
may be made of any suitable material.
The impressing writing pen is illustrated in the accompanying Drawing, and is
an ordinary style with a specially shaped point fixed to it.
This point a can be made of steel, bronze, hard india-rubber, ivory, or any other
suitable substance, and, as will be seen from the Drawing, is made in a hollow form
supplied with side slits b, b. Both ends of this cavity are solid, one of which is a
thick end provided with a plain pin or a screw for the purpose of joining the
holder c, the other is a thin end, and pointed, and is slightly rounded at the point.
Four fine channels d, d, run to this point as continuations of the narrowed ends
of the slits b, b, so as to enable the point to communicate with the interior of the
cavity e by means of these channels and slits.
When dipping the pen in ink a quantity of fluid is retained in the cavity, and
flows therefrom when writing to the point through the above-mentioned small
channels, and the pen is thus used like an ordinary steel writing pen.
The particular shape and firmness of the point allows the application of the
"weltpostfeder," as I call this new pen, for manifold purposes.
While writing with ink on the top sheet of paper the pen impresses at the same
time a second and even a third copy on sheets of paper placed underneath, after
having been each covered with a sheet of ordinary prepared transfer paper.
The advantages obtained from the "weltpostfeder" are,-
1st A usual ink cony. &c.
