of Prussia, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
STAMPING NEEDLES."-A communication from Francis Kayser, residing

subsequently to be formed.
According to this Invention machinery for stamping needles is con-
structed and arranged to act in the manner herein-after described. The
lengths of wire are placed horizontally in a funnel-shaped hopper having
vertical ends, and with sides sloping towards one another from the top
to the bottom of the hopper. At the bottom of the hopper is a roller
having longitudinal channels cut in it, each of a depth to receive one of
the lengths of wire. A step-by-step revolving motion is given to this
roller, and at each step one of the wires is delivered from the hopper
and falls down horizontally on to forks which support it in front
of a fixed bed or matrix; a hammer or stamp is then thrown forward
against it by a powerful spring, and the wire is flattened between the
bed or matrix and the stamp. Afterwards the stamp is drawn back by
a cam, and the stamped needle is thrown out by a moving finger or
wiper from the fork in which it previously rested.
The giving a step-by-step motion to the channelled roller, the drawing
back of the hammer or stamp, and the working of the finger or wiper
for ejecting the stamped needles, are all effected by cams on one shaft,
and this shaft is supported in bearings on a frame, which also carries
the hopper and fixed bed or matrix before mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Georg Printz in the Great Seal Patent Office
on the 13th August 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORG 2
PRINTZ, of Aix-la-Chapelle, in the Kingdom of Prussia, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of February, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors, give and 3
grant unto me, the said Georg Printz, Her special license that I, the
said Georg Printz, my executors, administrators, and assigns, or such

page_text: and the stamped needle is thrown out by a moving finger or wiper from
the fork in which it previously rested.
The giving a step-by-step motion to the channelled roller, the drawing
back of the hammer or stamp, and the working of the finger or wiper
for ejecting the stamped needles, are all effected by cams on one shaft,
and this shaft is supported in bearings on a frame, which also carries the
hopper and fixed bed or matrix before mentioned.
Figures 1 and 2 shew opposite side views of a needle stamping
machine constructed as above described; Figure 3 shews a front view,
and Figure 4 a plan view of the same.
In these Figures A is the horizontal frame of the machine supported
on standards B; C is the driving shaft supported in bearings D and
carrying the cams for imparting motion to the several parts of the
machine. This shaft receives motion from a belt working on the fast
and loose pullies C³, and has fixed upon it the cams C³, C³, C4, and C³;
the cam C² draws back the stamper or hammer E. The cam C³ gives
a step-by-step revolving motion to the grooved roller F; the cam C*
actuates the wiper or finger for ejecting the stamped wires, and the
cam C' moves the wires endwise up to a fixed stop previous to their
being stamped; G is the hopper into which the lengths of wire to be
stamped are placed; this hopper and parts connected with it is shown
on a larger scale at Figures 5 and 6; it has vertical ends, whilst the
sides incline downwards towards one another. The bottom of the hopper
is closed by the grooved or channelled roller F, the grooves in which are
each of a depth to hold one wire; on the axis of this roller is fixed a
ratchet wheel F¹, and this has a step-by-step revolving motion imparted
to it from the cam C³. For this purpose the cam acts upon a roller on
a sliding rod K, the end of which is adjustable and can be raised or
lowered by turning a screw, as shewn. This adjustable end piece acts
upon the inclined end of a lever H, which lever carries a pawl engaging
with the teeth of the ratchet wheel F'; the amount of motion given by
the cam C³ to the grooved roller is adjusted by raising or lowering the
adjustable end of the rod K. As the lengths of wire are carried round in
the grooves of the roller F they are delivered one by one into the wire
forks L, which retain them in front of the fixed bed or matrix M until
they have been stamped. The cam C³ acts upon a projection upon the
stem of the hammer E to draw the hammer back until the cam arrives

page_text: at such a position that the projection on the stem of the hammer is free
from it; the hammer is then thrown forward by the spring N towards
the fixed bed or matrix M. The strength of the blow can be adjusted
by compressing the spring more or less by the screw N¹ after each wire
has been delivered by the grooved roller F into the forks L, and before
it is struck by the hammer the slide O is by the lever O¹ and interposed
spring caused to act against the end of the wire, and hold the wire up to
a fixed stop, the lever O¹ being acted upon by the cam C³. The hammer
is then thrown forward against it by the spring N, as before described,
and afterwards the stamped wire is thrown out from the forks L by the
fingers P; these are mounted on an axis P', which is caused to rock
each time that a stamped wire is to be ejected. For this purpose the
cam C acts upon a lever Q, which by a connecting rod Q' is connected
to a lever arm on the axis P'; the grooved roller at the bottom of the
hopper containing the lengths of wire is then caused to turn one step, as
before described, and deliver another length of wire to be stamped when
the same operations are repeated.
Having thus described the nature of the Invention, and the manner
of performing the same, I would have it understood that what is claimed
is, the combined arrangement of machinery for stamping needles, sub-
stantially as herein described.
In witness whereof, I, the said Georg Printz, have hereunto set
my hand and seal, this Thirty-first day of July, in the year of
our Lord One thousand eight hundred and seventy-two.
GEORG PRINTZ. (L.S.)
