Improved Apparatus for Doubling and Twisting Yarns, and. Threads,
and for Covering Strands with Yarns or Threads.
GEORGE HILTON SMITH Machinist, Irk View, Rhodes. Middleton, near
Manchester BENJAMIN COOPER Yarn and Cloth Agent, 405 Cheetham Hill
Road, Manchester. do hereby declare the nature of this invention to be as
follows:-
Our improvements consist in twisting two or more yarn threads together in. the.
following manner.
To produce twofold yarn we place a cop or pirn on a tubular spindle then pass
a thread through a tube which joins the thread on the tube and the two are wound
together.
The thread coming off the tube wraps round the one passing through the tube,
thereby twists or turns are produced in the doubled yarn.
To increase the number of twists or turns obtained by the foregoing process we
rotate the tube or tubular spindle thus producing the number of twists or turn's
desired.
To produce three or more folds we pass an additional thread or threads through
the tube as may be required:
Straight strand covering is obtained by passing the strand through the tubular
spindle and treating in the foregoing manner.
After treating the yarn as before named we can subject it to another process of
twisting by placing the said yarn on a spindle from which it is wound whilst the
spindle revolves thus producing any number of twists or turns that may be
desired.

COMPLETE SPECIFICATION.
Improved Apparatus for Doubling and Twisting Yarns and Threads,.
and for Covering Strands with Yarns or Threads.
We GEORGE HILTON SMITH of Irk View; Rhodes, Middleton near
Manchester Machinist and BENJAMIN COOPER of 405 Cheetham Hill Road,
Manchester Cotton Yarn and Cloth Agent both in the County of Lancaster 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:-
Our improvements consist, as to the doubling and twisting process, in placing a
cop on a tubular spindle or tubular skewers through which spindle or skewers a
supply of one or more threads is passed to join the thread from the cop on the said
tubular spindle.
The thread in coming from the cop on the tubular spindle, wraps round the
thread or threads passed through the tubular spindle, thus producing a twisted
thread: The twisted thread then passes through friction pads or brushes and over
tension rods on to bobbins or tubes.

page_text: Having obtained the folds of yarn required on bobbins or 'tubes as before
described the same is subjected to another twisting process to give the number of
twists desired.
As to the process of covering strands with yarns or threads, the strand is passed
through a revolving tubular spindle and covered with yarn from the cop on the
revolving spindle.
In order that our invention may be more fully understood we have caused to be
annexed hereto five sheets of drawings indicating like parts in the various figures.
Figures 1, 2, & 3 are side sections of the winding or first process, Fig. 4 side
section of twisting or second process, Fig. 5 plan of Fig. 4. Fig. 6 side section of
winding on pirn or in cop in twisting or second process. Fig. 7 hollow or tubular
skewer with tip or plug.
Fig. 1. a, is a pirn bobbin which revolves in conical cup, actuated by means of
the rod c with driving pin c 1 which fits in groove of bobbin. The rod c a portion
of which is square, is caused to revolve by the hollow spindle d, in which is a
square hole to fit the rod c. On the hollow spindle d, is attached a wharve e which
is driven by means of a string in the ordinary way. f is a guide rod, g a stationary
drag rod, h a cylindrical brush, j &j 1 are the 'single yarn cops, k is an ordinary
skewer, 1 is a hollow skewer, la slotted tube on which is fixed k 1. In winding,
the yarn is taken from ; and passed through the tubes 1 and k 1, then joins the
yarn taken from 1 and passes through h and under the rod g, over the rod f and
on to the pirn bobbin. As the bobbin is being wound, the cup causes it to rise
automatically until full, it then having raised the square portion of the rod c
above the square hole in driving spindle d., ceases to revolve and thereby prevents
waste or over-winding.
j
Fig. 2. & 1 are single yarn cops mounted on the ordinary skewers,j 2 is a yarn
cop mounted on a tubular spindle, m, which revolves in bearings n & n 1 and is
turned by the band o, from the roller p. The yarn is taken from j & j1 and
passed through to spindle, m, which then joins the yarn taken from 2 and passed
through the cylindrical brush and round on the pirn as shown and described in
Figs. 1 & 3.
Fig. 3. a. is a double headed bobbin placed on spindle 6 mounted in bearing c & c 1,
which is caused to revolve by means of a wharfe and band in the ordinary way.
d is a rod to guide the yarn on the bobbin a, which is actuated by a heart or cam
motion.
The yarn is taken from the cops as shewn and described in Figs. 1 & 2, and
wound on the bobbin a.
In Figs. 1. 2 & 3 a reel or swift on which is put yarn in the hank and placed in
the positions of the cops j in Fig. 1 and 3 or j and j1 in Fig. 2. the yarn being
taken from the bank and passed through the hollow tube and skewer k 1. as
shewn in Figs. 1 and 3 or passed through the hollow spindle m.
Fig. 2.
as shewn in
Fig. 4. a. is a drum, driving the spindle on which is mounted the bobbin or
pirn c. as shewn in Figs. 1. 2 & 3. The yarn is then taken from the bobbin c and
passed through the guide hook d between two list-cloths e & e 1, and over the
guide fon to the bobbin g. The periphery of yarn wound on bobbin g. is caused
to press on the drum by means of weights or springs and the drum & being driven
at the speed required to give the necessary number of turns, as the yarn is drawn
from the revolving spindle.
One or more bobbins may be placed to work on the drum as shewn by g.g 1 & g 2.
Fig. 5. This figure is a plan shewing the position of the twisting spindles and the
manner in which the yarn passes from the spindles to the bobbins
9. 9 1. & g 2.
k. k 1 & 2. are weighted centres on which are placed the bobbins g. 9 1 & g 2.
At each end of k. k 1 & k 2 are pivots which work in the slots of the frames ; & j1
so as the bobbin fills, the pivots rise in the slots.
Fig. 6. This figure shews the method of taking the yarn from the twisting
spindles over the guide hook d through the listing e & e 1 and from the hooks fon

page_text: to the faller wire g, and under the guide wire h, on to the spindle i. In the
formation of the cop the same or similar methods are applied as are now in use on
the mule or jenny-viz. by a shaper or tappet.
The spindle i may be caused to revolve by means of a multiple treaded worm and
worm wheel thus giving a positive number of turns.
9.
To cause the faller wire g. to move in harmony with the varying diameters of
the chase. We fix a shaper to the chase shaper which actuates the faller wire
independant of the faller wire h. so that as the shaper of the chase is moved in
position to give the required form to the cop, so will the shaper of the movement
of the faller wire g. be moved into position to give the required rise and fall, to
take the yarn at a uniform rate from the bobbin c.
Fig. 7. This figure shows the tubular skewer a with tip b. By unseating tip
into the small end of skewer a. it enables the skewer a. to be passed through a cop
more readily.
Having thus described our invention and the manner in which the same can be
performed-we claim
Firstly. The placing of a cop on a tube or hollow skewer for the purpose of
passing a thread or threads from other cops, bobbins or hanks through the tube or
hollow skewer.
Secondly. The placing of a cop on a revolving hollow or tubular spindle, and
pass one or more threads through the spindle as shewn in Fig. 2 and also for
passing through the tubes a strand for covering with yarn as before mentioned.
