IMPROVEMENTS IN MACHINES FOR THE MANUFACTURE OF NEEDLES
Year: 1875

page_text: PROVISIONAL SPECIFICATION left by Frank Wirth at the Office of
the Commissioners of Patents, with his Petition, on the 25th
February 1875.-A communication from Hubert Fritz Neuss,
Manufacturer, residing at Aix-la-Chapelle in the Empire of
Germany.
I, FRANK WIRTH, of the Firm of Wirth and Company, Patent
Agency, of Frankfort-on-the-Main, in the Empire of Germany, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINES FOR THE MANUFACTURE OF NEEDLES," a communication, to be as
follows:-
The said machine rests on a foundation stone; it has a block and
frame of one and the same piece; on the block there is an anvil which
may be exactly adjusted by means of four screws; one half of the
matrix is joined in the anvil the other in the hammer; the hammer is
guided by two rulers affixed to the frame of the machine; the said
hammer is lifted and allowed to fall by means of a cord to which the
hammer is affixed; it passes over a roll and is drawn on by the foot of
the workman; the latter places the needle with his hands on the lower.

with the foot are converted into automatic machines, which can be
driven by steam; the old machines need not be altered in any way;
all that is necessary is to screw the new pieces to the old ones; this
circumstance is of great importance because the manufacturer can thus
get very cheap machines, which besides can readily be mastered by an
intelligent workman.
.
As new and particular in this machine I consider the manner of
guiding the needle shafts after having been sharpened; a certain amount
of double needles are laid in a tin box; for the different lengths boxes of
different sizes are required; the same are affixed in a slit of a pedestal
by means of screws, which taper towards their lower part; the opening
of the box is exactly over the bow so that the latter can just be moved
to and fro under the box; without that a needle is taken with it; the
box can be placed on the right height by means of the screws which
may be moved in a slit of the bearer; the said bearers can be placed in
the proper position by means of a slit and screw; on each end and
towards the upper side bow is provided with a small groove which is
exactly as deep and as wide as the needle; at the back the bow is
screwed on the carriage with two small screws ; by a to-and-fro
movement the groove of the bow is once brought under the box, with
the needles once under the falling hammer; a sledge moves in a support
which may be turned around on its axis; in order to place the support
properly an angle is screwed to the block of the machine; in this angle
two regulating screws are turned in; these two screws act on a piece
affixed to the support, thus the latter can be inclined more or less; the
axis of the support turns in two pieces screwed to the block; the to-
and-fro movement of the carriage is caused by means of a lever; the
same has its turning point in the fork which is screwed to a bow; the
lever draws the carriage with it by means of two angles screwed to the
carriage; the said lever can move freely in the keyed pivot; on the upper
end it bears a steel roll which is carried in a groove of a disc; this
groove is constructed in such a manner that a peculiar motion is
imparted to the carriage; the latter is thus first led to the hammer where
it remains for a moment until it has come down; the carriage is then
moved back in order to execute a short to-and-fro movement at the end
of the stroke; hereupon it is again led to the hammer; this short to-
and-fro movement takes place in the same moment when the grooves of

page_text: the bow are under the box filled with needles; the said disc is keyed to
the main axis on which the fast and loose pulley are also attached; the
axis turns in the socket of the bow which is screwed to the main bearer
of the machine; a lifting cog is also keyed to the axis which seizes the
roll screwed to the angle with which the hammer is united.
The apparatus for throwing off the stamped needles consists in the
following parts:-On the carriage there is a long spring which is
prodvied with a small hook on its end; when the carriage goes back
this hook catches a corresponding shoulder of a disc resting on an axis;
levers resting on the same axis and laying aside of the matrix are thus
moved upwards and throw the stamped needles from the grooves to a
box standing in the front of the machine; as soon as the spring has
drawn the disc around, the shoulder goes also so much round that the
spring ceases to catch; the axis with its two levers returns to its former
position in the forked bearers.
