COMPLETE SPECIFICATION.
A New or Improved Method and Apparatus for Manufacturing Steel
Pens.
I, CARL SMITT, of Scheelegatan No. 13, Stockholm, in the Kingdom of Sweden,
Engineer, 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:-
The first operations in the manufacture of steel pens in before known manners
consist firstly in cutting the pens out of steel strips. The pens are then marked
with name, number etc., and finally they are provided with suitable openings or
slits and the pen is pierced etc. These first operations may thus be executed when
the blank is quite flat. The above mentioned method has the great inconvenience
that every pen blank that is cut out, in order to be marked, pierced, cut etc., must
be put into the different pressing and cutting machines by hand. Of course this
is a time wasting as well as a difficult work and there is usually formed a
pen blanks
great quantity of so called langrage, that is to say, a great number of
must be rejected for the reason that they have been put into the machines in a
wrong way. To the above stated inconveniences is also added a rather great
danger for the workers in marking the pens.
This invention has for its object the removal of the above stated inconveniences.
By this invention all the operations are executed by one and the same machine,
which works in such a way that all stamps, holes and cuts etc., for every pen are
applied on and into the strip before the pen blanks are cut out of the steel sheet.
After the cutting out of the pen the blank is thus ready to be bent into proper
form and hardened, polished etc.
For this purpose a common eccentric-press can be used.
Fig. 1 in the annexed drawing is a view from below of the holder for the
punches of such a press arranged according to this invention. The steel strip
is supposed to be moving forwards in the direction of the arrow a, that is, from
left to right on the drawing. The strip is thus first operated upon by the stamp b
which provided for instance with the name of the pen or the manufactory or
both and a letter (in this case the letter F) or any other indication, characterizing
the hardness, pointedness etc. of the pen in question. Of the following stamps c
and d, which prepare the pen blank, the first one e makes the hole and side cuts
in the pen. The second stamp d presses for instance the number into the pen,
which number becomes situated directly under the name pressed in by the
stamp b, or said stamp d may pierce a hole in the back of the pen.
In Fig. 2 there are illustrated by dotted lines two ready stamped and pressed
sections of the strip and from every such section a pen blank may afterwards be
stamped out by the outermost stamp e. Fig. 3 illustrates the pen blank stamped
in the said manner.
All the stamps b c d and e are naturally raised and lowered at the same time,
all being secured to the movable punch holder f. In order to easily change and
adjust the mutual distance and position of the stamps, the same are fastened to
two clamps g and h, which are movable laterally in the punch holder, f. They
are retained in this holder f by screws as shown in the drawing. The said

page_text: holder and the whole arrangement may be modified in many ways, only that
the condition, characterizing the invention is fulfilled, that is to say, that the
stamps for the name and the smaller stamps for 'the holes and cuts are put in before
the cutting out stamp, so that the blank is not cut out before all stamps and
smaller hole stamps etc. are made.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A method of manufacturing steel pens, consisting therein, that on every
part of the steel strip where a pen blank is to be cut out, all stamps, holes, cuts
and the like are applied by suitably arranged stamps before the pen blank is cut
out of the said steel sheet or strip.
2. A machine for execution of the method described in Claim 1 substantially as
described and shown in the drawing.
Dated this 3rd day of November 1800.
