Berlin, in the German Empire. "IMPROVEMENTS IN COP SPINDLES, AND
APPLIANCES CONNECTED THEREWITH, FOR CONTINUOUS SPINNING MACHINES."
[A communication by Richard Sehrke and Messrs. Büldge and Hildebrandt, all

This Invention has for its object to maintain in continuous spinning machines
a constant length of thread from where it leaves the drawing rollers to the point
of the spindle where it is being wound on, by which means a uniform amount of
twist will always be imparted to equal longths of thread. For this purpose instead
of causing the ring or other mechanism by which the thread is laid on to the cop
of the spindle to travel up and down along the cop spindle, as heretofore, the said
ring is made stationary, and the cop spindle is caused to travel up and down
through the same so as to have the thread applied successively along its whole
length. For this purpose the lower ends of the cop spindles are mounted in
bearings in a framing or rails, that is or are made to travel up and down with
the spindles by any convenient known mechanism; and in order to avoid com-
plication of the driving mechanism with this arrangement the whirl by which
rotary motion is imparted to the spindle is not fixed thereon, but runs with a
collar in a fixed rail or bearing, while the spindle is made to slide up and down
through the same, and is at the same time caused to revolve therewith either by
forming a longitudinal groove in the spindle in which gears a feather or stud in
the boss of the wheel, or by forming the spindle of polygonal section, and the boss
of the whirl with a correspondingly formed hole.

GERARD WENZESLAUS VON NAWROCKI, Proprietor of the Firm of J. Brandt and
G. W. v. Nawrocki, Patent Solicitor and Engineer, of No. 124, Leipzigerstrasse,

A communication by Richard Schrko and Messrs. Büldge and Hildebrandt, all
of Berlin, in the German Empire.
This Invention has for its object to maintain in continuous spinning machines
a constant length of thread from where it leaves the drawing rollers to the point
of the spindles where it is being wound on, by which means a uniform amount of
twist will always be imparted to equal lengths of thread. For this purpose instead
of causing the ring or other mechanism by which the thread is laid on to the cop
of the spindle to travel up and down along the cop spindle, as heretofore, the said
ring is made stationary, and the cop spindle is caused to travel up and down
through the same so as to have the thread applied successively along its whole
length. For this purpose the lower ends of the cop spindles are mounted in bearings
in a framing or rails, that is or are made to travel up and down with the spindles
by any convenient known mechanism; and in order to avoid complication of the
driving mechanism with this arrangement the whirl by which rotary motion is
imparted to the spindle is not fixed thereon, but runs with a collar in a fixed rail
or bearing, while the spindle is made to slide up and down through the same, and
is at the same time caused to revolve therewith either by forming a longitudinal
groove in the spindle in which gears a feather or stud in the boss of the whirl, or
by forming the spindle of polygonal section, and the boss of the whirl with a
correspondingly. formed hole.
DESCRIPTION OF THE DRAWING.
The accompanying Drawing shews two out of a range of spinning spindles to
which this Invention is applied, the bearings and driving wheel for one of these
spindles being shewn in elevation, and for the other in section. The spindles S
revolve in the lubricated bearings 1, l','formed respectively in two bars B, B¹,
which are rigidly connected together, and caused to move up and down, so that
while the yarns are guided always in one direction by the stationary rings R, the
spindles present successive parts of their length to receive the convolutions of the
yarn on them. The lower parts of the spindles are of polygonal section, or have
key grooves, as shewn, to receive studs or keys projecting inwards from the driving
whirls W, so that while the spindles are free to slide longitudinally through the
whirls, they must revolve with them. The whirls W have bosses passing through
holes in a stationary rail and collars secured on those bosses which revolve in oil
boxes H, the whirls being thus kept in a constant position.
Having thus described the nature of this Invention, and in what manner
the same is to be performed, as communicated to me by my correspondents, I
claim,―
In continuous spinning machines the employment of stationary rings or guides
for the yarns in combination with spindles that are moved up and down through

page_text: the bosses of their driving whirls, while they revolve therewith, substantially as
and for the purposes herein set forth.
In witness whereof, I, the said Gerard Wenzealaus von Nawrocki, have
hereunto set my hand and seal, this Ninth day of September, in the year
of our Lord One thousand eight hundred and eighty one.
