is passed round a pulley, and, pressing downward, causes the hammer to
ascend. Taking a handful of blanks with her left hand, by a dexterous
motion she makes a little train of them between the thumb and finger
in parallel order, presenting the first in the most ready position to
be passed to the other hand. The right hand is brought toward the
left, and, taking a blank, places it with the point toward the worker
in a guide upon the bed of the stamp, then by suddenly letting the
hammer descend a blow is struck upon the blank, which gives an
impression of the name cut upon the punch. The quick fingers of the
operator pass backward and forward with such rapidity that a skillful
girl will mark from two hundred to two hundred and fifty gross per
day. If the mark required is unusually large, the marking process is
deferred until after the pen has been pierced, in order that the blank
may be annealed (or softened), which takes the impression more readily
than the hard steel.
Now, in order to make a metallic pen suitable for writing it is
necessary to consider some means of producing elasticity, and also to
devise some method by which the smooth steel shall cause the ink to
attach itself to the pen. This is brought about by the next process--
_piercing._ In this operation the tools are of a very delicate
character, and as the center pierce (the aperture in which the slit
terminates) is frequently of an ornamental design the tools, being
small, have to be made with great precision. The piercing punch and
bed having been fixed in a screw press, and an ingenious arrangement
of guides fastened thereto, the girl selects a blank from a tray on
her left hand, and, placing it in its proper position by the aid of
the guides, pushes the fly of the press from her, the screw descends,
driving the punch into the bed, and the operation of piercing is
completed.
The blanks are still moderately hard, and before they can be made to
take the shape of a pen it is necessary that they should be softened,
which is effected by the process called _annealing._ The blanks
having been freed from the dust and garbase that has become attached
to them are carefully placed in round iron pots, which are again
inclosed in larger ones and covered over with charcoal dust to prevent
the entrance of gases, and put into the muffle, heated to a dull red,
and then allowed to cool.
