We,
FRIEDRICH HEROLD and WILHELM VAN GULPER, both of Schwabach,
Nurnberg in the Empire of Germany, 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 :-
This invention for a needle sorting and tempering machine has for its object to
provide a machine which effects firstly the sorting at present done by hand of
sewing, darning, dress makers and other needles generally and of packing needles,
and secondly the tempering of the points or heads thereof.
In the accompanying sheet of illustrative drawings
Figs. 1 and 2 are side and end elevations respectively of a needle sorting
machine constructed according to this invention. Fig. 3 is a plan of the same.
Fig. 4 is an elevation of part of the machine fitted with needle tempering
apparatus.
Fig. 5 is a plan, and Figs. 6 and 7 are detail views.
With reference to Figs. 1, 2, 3 and 6 in which the machine is arranged for
sorting the needles, needles of one size and length, with the heads and points lying
under each other indiscriminately are laid on the slanting surface f according to
the length of needle which it is adjusted for, from whence they are taken by a
rubber tyred rotating disc e, forced thereby close over the saddle m and conveyed
singly on to the screw / rotating at the top near and parallel with a glass rest g.
The rotation of the screw h causes the needles resting in its threads to come
against the glass rest which is adjusted so far from the screw h, Fig. 6, that the
needles, whose heads bear on the angle of the glass rest are moved into the box n,
whilst needles whose points rest on the angle of the glass rest fall, owing to the
greater weight of the head, on to the obliquely inclined plate o fixed underneath
the screw hand from thence into the box g underneath so that the needles as far
as possible are arranged with their respective heads and points together. The
table plate is as shown in Figs. 3 and 5 suitably cut away.
The machine is driven from shafting by means of the belt pulley a on the axis
of which one half of a claw or similar coupling is adjustably fitted and capable of
being fixed, whilst the other half of the coupling is fixed to the cone pulley b
mounted loosely on the axis and adapted to be put in or taken out of gear by the
lever moving in either direction.
The cone pulley b, serves to regulate the capacity of output of the machine with
the various kinds of needles.
The step pulley i, mounted underneath the table in the front frame, serves to
regulate the speed of rotation of the screw h for different sizes of needles.
If for example the disc e supplies in one revolution 160 needles to the screw h,
then the latter must naturally inake 160 revolutions in the same time in order
that any collection of the delivered needles and therewith any damage, may be
prevented.

page_text: All the pulleys are movable in two directions on their axes, so that the
In order
adjustment of the machine for different speeds can be quickly effected.
to regulate the tension of the belts on the pulleys and with the different rates
of transmission, the bearings thereof are movable in two directions by means of
screws as shown in the drawing.
If the belt on pulley b is transferred from one step to another, the bearing of
the axle is moved in order to give the proper tension.to the belt, and the lever ris
unscrewed, properly adjusted on the cross disc, and again screwed tight.
For two sizes of needles one screw h acts, and there are 12 such screws provided,
so that 24 sizes of needles can be dealt with.
If desirable the number of the screws h and also the number of the steps on the
pulleys band i can be increased or diminished.
The screws are provided with triangular, square, etc. heads and are, when
replacement is necessary, inserted in the axis of the disc u under the saddle m,
the standard being first unscrewed and when the replacement is effected again
screwed tight.
The glass rest g Fig. 6 is likewise arranged to suit the different lengths and
thicknesses of the various kinds of needles being capable of vertical and lateral
adjustment and can be adjusted close up to the screw h.
The inclined plane with the on-lay plate standing thereon and the collecting
box n are also made movable to both sides of the screw h, so that the particular
kinds of needles are fed, in a straight line downwards from the inclined plane f
along the on-lay plate, to the glass body g through the screw h into the box. n.
Corresponding to the various needle lengths, rubber tyred discs e of different
widths and saddles m, are used, and the ribs of the inclined. plane fare adjusted to
correspond, in order that the particular kinds of needle may lie firmly thereon and
run exact.
The feed wheels or discs e are of the same diameter and are by means of their
axle bearings, either raised or lowered with the different sizes of needles.
The saddles m are arranged in one piece with the frame cover next the screw h,
and separately for the purpose of replacement.
The box q can, as shown in Fig. 1 be pushed in at different heights.
For the tempering of the needles the arrangement shown in Figs. 4, 5 and 7 is
employed, the box g and the plate o Figs. 1, 2 and 3 being first removed and in
place of these the gas apparatus t provided with the toothed rods is fastened
underneath the table by means of the slide runners v.
The racks engages in the pinion attached to the axis of the hand wheel y
fitted above the table and by turning the hand wheel y right or left the gas
apparatus can as desired be moved forwards or backwards. The gas apparatus
has three divisions forming the burners running parallel with the screw and
perforated at the top, which are connected with three cocks fitted at the front, so
that the needles may be heated as desired according to the length or size, since
the gas from one, two or all three cocks may be used at the same time to heat the
needles.
The adjustments of the machine in tempering have to be regulated as in sorting

page_text: with the difference that the laying on plate on the plane f, the glass body and
the collecting box n must be so set that the needles cannot fall on to the gas
apparatus. The gas apparatus is so arranged that it can be, like the glass rest,
placed quite up to the screw h Fig. 7.
If the needles are to be tempered at one end, either at the heads or only at the
points, then they must be previously sorted.
If on the other hand it is desired to temper both heads and points then the
needles can be tempered when unsorted and then afterwards sorted whereby a
working operation is saved.
If it should happen that the needles to be treated, for example darning or
packing needles and especially flat headed needles, only move slowly on to the
screw and the glass rest g, this difficulty is overcome by the table plate being
raised at the front by the screws p, in which operation it rotates at the back
about the bolts pl. By the raising of the table plate the screw h meets the
inclined plane and the needles then come with a rolling dropping movement.
.
The tray shown in Figs. 1 2 and 3 serves to hold the spare parts belonging to
the machine, such as the screws h the saddle m the feed wheels e and other tools.
The place above the tray k on the table serves to hold the needles to be worked,
and the machine is so arranged that a sitter can work thereat.
Having now particularly. described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
-
1. A needle sorting and tempering machine characterised by the combination of
the adjustable inclined plane with the feed wheel e, the saddle m, the adjustable
glass rest g and the screw h, which sorts the needles promiscuously placed on the
inclined plane f in such manner that the needles sliding with their heads on the
corner of the glass rest are fed by means of the screw into the central case n,
whilst the needles whose points slide on the angle of the glass rest, owing to the
excess of weight of their heads, fall on to the plate o and slide into the adjustable
case whereby the needles are sorted.
2. A needle sorting and tempering machine characterised by the adjustability of
the speed of rotation of the feed wheel e and the screw h, required by the different
lengths and thicknesses of needies, by means of the step pulleys bi in combination
with the bearings adjustable in two directions, the adjustable lever r operating to
put the cone pulley b in or out of gear and the adjustable coupling a¹.
3. The arrangement of a gas apparatus t sliding in grooves v with a rack s
engaging in the pinion on the hand wheel y by means of which the gas apparatus
provided with several cocks and perforated partitions from above by means of the
hand wheel y is adjusted for suitably heating or blueing the heads or the points of
the needles.
4. The arrangement and construction of needle sorting and tempering machines
substantially as described with reference to the drawings.
