GEORGE ROPER, of Stockport, in the County of Chester, Draper. "IMPROVEMENTS
IN MECHANISM OR APPARATUS TO BE EMPLOYED IN THE TWISTING AND DOUBLING
OF YARN."
To this
My Invention relates to improvements in the method of and apparatus for
twisting and doubling yarn in the process of twisting and doubling the same,
whereby a better twisted yarn is produced and the production increased.
end I spool in the ordinary manner any desired number of threads, either in the
cop" or "bobbin " form. The said cop or bobbin I mount on a suitable spindle
which is attached to a disc or frame fixed to the ordinary revolving spindle. To
the said revolving spindle I form or attach two discs or frames of a circular or other
form; I mount the lower disc or frame above the bolster of the said spindle and the
upper disc or frame near the top of the said spindle. I may connect one or more
cop spindles or bobbins to the lower disc or frame, and which may be arranged in
a circular or other form. The said connection may be made by passing the spindle
containing the cop through a hole in the said disc or frame, and screwing on to the
end thereof a suitable nut. I lead the yarn from the said cop through a second
disc or frame formed with any required number of holes. Each hole may be lined
with felt or other suitable material, to polish and take away superfluous matters
which may be attached to the yarn. The required tension of the yarn is obtained
by passing it through one or more holes, as desired. I am thus enabled to place
any required tension thereon. The said spindle may be arranged to revolve either
in a vertical, inclined, or horizontal direction or position, as required. Any suitable
arrangement for wetting or gasing the yarn may be employed in connection with
my said Invention. I am enabled to dispense with the employment of a flyer,
formerly employed.

GEORGE ROPER, of Stockport, in the County of Chester, Draper. IMPROVEMENTS
IN MECHANISM OR APPARATUS TO BE EMPLOYED IN THE DOUBLING AND TWISTING
OF YARN."
My Invention relates to improvements in machinery or apparatus employed in
the doubling and twisting of yarns or threads, and consists in the combination and
employment of parts forming a circularly creel, consisting of an upper and lower
circular disc or frame of metal mounted on a spindle. The lower disc or frame is
formed with conical slots, into which slots the conical or taper ends of cop skewers or
spool pins are placed and are rotated therewith by the said spindle. When mounting
spool pins on the said lower disc I form lugs on the lower ends thereof, to which
the spool tubes are locked. In the said upper disc or frame I form a number of
tension holes and fit therein corresponding eyes or tubes of glass, through which the
yarns or threads are led. Any desired tension or tightening of the yarns or threads
being doubled and twisted is obtained by passing or leading them through one or
more of the said tension holes. In ordinary doubling frames the yarns or threads
have but one twist or turn imparted to it for one revolution of the take up spindle,
by reason of its being only twisted at one end thereof. I am enabled by my Inven-
tion to impart two positive twists or turns to the yarn or thread for one revolution
of the take up spindle, by reason of twisting the same at both ends thereof at the
same time, which I consider to be an advantage. The yarns or threads to be doubled
and twisted are led from the cops or spools fixed on the lower disc first through outer
tension holes in the upper disc, the ends are brought together and passed through
an inner tension hole, where they become doubled. The yarn or thread is then
passed through a second tension hole, when a twist is imparted to it by the
revolution of the said circularly creel. The yarn or thread may then be led through
guide eyelets and through a water trough or gasing apparatus, if desired; thence
between drawing rollers and through the eye of a rotating flyer or ring tube, to the
take up bobbin or spool tube, on which the doubled and twisted yarn or thread is
wound in the ordinary manner. A sheet of tin may be fixed on the lower disc when
mounting only two cops or spools thereon, in order to prevent or lessen the forma-
tion of a draft by the rotatory motion of the cops or spools, but it will not be
found necessary when four or more cops or spools are rotated.
And in order that the Invention may be better understood I have caused to be
appended hereunto a Sheet of Drawings marked with letters of reference. Referring
in this place to the said Drawings, Figure 1 represents a cross sectional elevation of
a doubling machine with my Invention applied thereto; Figure 2 is a front elevation
showing two creel spindles c, c, on each of which the circularly creel A is mounted,
and is rotated thereby; Figure 3 represents the said creel A drawn to a larger size,
and Figure 4 a plan of the same. In the example illustrated two cop skewers bare
shown mounted on the lower disc or frame d of the said circularly creel, but it must
be understood that three or more may be mounted thereon if desired. The cop-
skewers b are of a conical or taper form at their lower ends, which ends fit into
taper slots in the lower disc or frame d, and are rotated therewith when the yarns
or threads are being doubled and twisted, or twisted when they are being wound in
a doubling winding frame. The upper disc or frame e of the said circulary creel is
formed with the outer tension holes e¹, through which the yarns or threads from the
cops a on the skewers b are first led, and with inner tension holes e³, . The yarns
or threads become doubled in the tension hole e, and afterwards twisted in the
tension hole e³. The said tension holes are suitably lined or fitted with eyes or tubes
of glass in order to offer the least friction to the yarns or threads. The doubled and
twisted yarns or threads are then led through the guide eye, thence through the

page_text: water trough g, through the eye h, and between the drawing rollers i, thence through
the eye of the flyer or ring tube, as the case may be, onto the bobbin K or tube K¹.
And important feature in my Invention consists in imparting two positive twists to
the yarns or threads for one revolution of the take up spindle m.
By the employment of the said circularly creel A I am enabled to twist the yarn
or thread at the delivery end, in addition for the twist at the take up end, as now
given in ordinary doubling frames. I am thus enabled by the indicated means to
twist the yarns or threads at both ends at the same time, that is to say, the yarns
or threads receive two positive twists for one revolution of the take up spindle. In
ordinary doubling frames the yarns or threads has but one twist or turn imparted
to it for one revolution of the take up spindle. The creel spindle c is driven by a
band p' from the take up spindle m passing over wharves or pulleys. The spindle
m is driven by means of bands from the driving drum o. The Invention is also
applicable to be employed to doubling winding frames, in which case the yarns or
threads are twisted during the time they are being wound, but I have not thought
it necessary to illustrate a machine showing it applied thereto. In my Provisional
Specification mention was made that the creel could be arranged otherwise than
vertical, but I have not found any other position to be of increased advantage; also
that the tension holes could be lined with felt, I have not found felt to be so
suitable as glass, and lay no claim thereto.
Having now described and indicated the nature and intent of my said Invention,
and means for carrying the same into effect, I wish it to be understood that I do
not confine myself to the precise arrangement herein illustrated and described, as
the same may be varied to some extent without departing from the principle features
of novelty of my Invention, but what I claim is,--
First. The combination and arrangement of parts forming a circularly-creel, and
consisting of a lower and upper disc or frame, the lower disc or frame being
slotted or formed to carry two or more cops or spools, and the upper disc or frame
with tension holes for doubling and twisting single and double yarns or threads,
substantially as described and as illustrated in the accompanying Drawings.
And, lastly. The manner and means for imparting two positive twists or turns to
the yarns or threads in ordinary doubling frames for one revolution of the take up
spindle, and for twisting the yarns or threads during the time they are being wound
in a doubling winding-frame, substantially as set forth.
In witness whereof, I, the said George Roper, have hereunto set my hand and
seal, this Fourth day of May, in the year of our Lord One thousand eight
hundred and eighty.
