PROVISIONAL SPECIFICATION.
A Doubling, Laying, and Twisting Machine.
I, GEORGE BYRON GREAVES UNSWORTH, of Green Lane Mill, Derby, Silk
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a machine for the production of cords of silk, cotton or
other fibrous material by twisting and laying together two or more strands so as to
form a cord with any desired amount of twist.
In the machine there is a spindle and on the spindle there is a sleeve, they are
both driven by gearing and by means of change wheels their relative velocities
can be varied as desired. This main spindle carries a plate and on the plate other
spindles with fliers are mounted so as to be able to turn. The plate carries two or
more such spindles according to the number of strands which are to be combined
into a cord. The strands are brought to the machine upon bobbins and these
bobbins are placed upon the flier spindles. On each of the flier spindles at its
lower end there is a pinion and the pinions gear with a toothed wheel fixed upon
the sleeve upon the main spindle. Thus the flier spindles can be made to turn
with any desired velocity relatively to that of the main spindle. From the bobbin
in each case its strand passes to the arm of the flier and thence to an eye or guide
passage in the head of the flier.
After leaving the fliers the strands are brought to the head of the main spindle
which is grooved to receive the strands and to lead them together. A cord results
from the laying together of the twisted strands and this is led upwards and passed
several times around a pair of grooved pulleys which are driven by gearing. It is
the rotation of these pulleys which draws the strands from off the bobbins; the
gearing can be changed to vary the lay. From the grooved pulleys the cord passes
to another, spindle by which twist is put upon it to any desired extent and the
finished cord is wound upon a bobbin upon this final twisting spindle or if sufficient
twist is put upon the yarn or cord without this final spindle it can go direct on to
a receiving bobbin driven in the usual various manner.

1, GEORGE BYRON GREAVES UNSWORTH, of Green Lane Mill, Derby, Silk
Manufacturer,.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 relates to a machine for the production of cords of silk, cotton or
other fibrous material by twisting and laying together two or more strands so as to
form a cord with any desired amount of twist.
In the machine there is a spindle and on the spindle there is a sleeve, they are

can be varied as desired. This main spindle carries a plate and on the plate other
spindles with fliers are mounted so as to be able to turn. The plate carries two or
more such spindles according to the number of strands which are to be combined
into a cord. The strands are brought to the machine upon bobbins and these

passage in the head of the flier.
Thus the flier spindles can be made to turn with
that of the main spindle. From the bobbin in

After leaving the fliers the strands are brought to the head of the main spindle
which is grooved to receive the strands and to lead them together. A cord results
from the laying together of the twisted strands and this is led upwards and passed
several times around a pair of grooved pulleys which are driven by gearing. It
is the rotation of these pulleys which draws the strands from off the bobbins ;
the gearing can be changed to vary the lay. From the grooved pulleys the cord
passes to another spindle by which twist is put upon it to any desired extent and
the finished cord is wound upon a bobbin upon this final twisting spindle.
Figure 1 of the drawings hereunto annexed is an end view and Figure 2 a part
front view of a machine constructed according to my invention.
Figure 3 is an elevation partly in section and on a larger scale of one of the
sleeves and spindle passing through it and the disc secured to this spindle.
A A are spindles in two parallel rows. Surrounding a portion of each of these
spindles is a sleeve B.
Each sleeve has fast with it a disc B¹-this rests upon a bushing B' which rests
upon the top of a fixed horizontal rail C. The sleeve projects downwards through
the rail and on its lower end has fixed to it a bevil pinion B³.
Each spindle A has fixed to it a horizontal disc A-this disc has standing up
from it two or more tubular uprights A². The spindle D' of a flyer D passes down
through each of these tubular uprights and has fixed on to its lower end a pinion D2-
this gears with a toothed wheel 133 fast on the sleeve B. Each spindle A has also
fixed upon it near its lower end a bevil pinion A3 by which it is driven. The lower
end of the spindle is received in a bearing in a fixed horizontal rail C¹.
The bevil pinions A³ of all the spindles in the two rows of spindles are driven
by bevil pinions E' on two horizontal shafts E.
The bevil pinions B3 of the sleeves which embrace the several spindles A are
driven by bevil pinions G' on two horizontal shafts G.
The two horizontal shafts E are made to revolve at the same speed one with the
other by pinions E2 upon them both gearing into an intermediate pinion F.
The two horizontal shafts G are made to revolve at the same speed one with the
other by pinions G2 upon them both gearing into an intermediate pinion H.
One of
The axes of the intermediate pinions F and H are driven at any desired speeds
relatively the one to the other by change pinions F H¹ on their axes.
these is driven by an intermediate wheel F2 from a pinion I¹ on a driving shaft I-
the other is driven by an intermediate wheel H² from the same pinion. By varying
the sizes of the pinions F' H' the shafts E and G can be driven at any desired
speeds relatively the one to the other.
Bobbins carrying the strands which are to be formed into a cord are placed upon
the upright A which stands up from the disc A' and the bobbins rest upon this
disc cloth or felt being interposed between them or other means adopted to give
the necessary drag. Each strand is led from its bobbin partly around an arm D³
and then under a pulley D₁ at the lower end of another arm of the flyer and then
over a guide pulley D and through the eye De from which it passes through a
similar eye A at the top of the spindle A.
The loosely twisted cord produced by the laying together of the strands by the
spindle A is led upwards and over guide pullies to grooved rollers K around which
it is led and then downwards to a flyer L by which it is wound on to a bobbin M.
The flyer spindle is driven by a bevil pinion upon it gearing into a bevil pinion N¹
on a shaft N which is itself driven by a toothed wheel upon it gearing with a
pinion O which by a toothed wheel P is geared to a pinion on the driving shaft I.
The grooved take up rollers K are driven from the axis of the toothed wheel P,
or in any other convenient way. On the axis of one of the rollers is a toothed
wheel driven by a worm R' on the top of a shaft R and on the lower end of the

page_text: shaft is a bevil pinion R³ which gears with a bevil pinion P¹ on the axis of the
toothed wheel P.
The second roller K is driven at the same speed as the first by a pinion upon it
gearing with an intermediate pinion which is also in gear with a pinion on the first
roller.
The bobbin M upon which the cord is to be wound is hindered from revolving
at the same speed as the flyer by any suitable drag mechanism preferably by a
cord passing around a pulley upon which the bobbin is supported. Preferably I
cause more twist to be put into the cord than it will retain when free and after
leaving the cord on the bobbins for some hours rewind it on to other bobbins and
at the same time taking off from it the superfluous twist.
By using positive take up rollers K to draw off the partially layed cord as it is
formed a hard and perfectly uniform twist can be put into the strands and by after-
wards putting in the remainder of the twist by a flyer as the cord is being wound
up on to a bobbin the machine can be driven at considerable speed as the flyer can
easily be driven at a high speed whereas the spindle A with the disc and two or
more bobbins carried by it can only be driven at a comparatively slow speed. Also
by driving the spindles A. and the flyer spindles D' by two separate trains of gear
wheels in the manner above described great facility is given for varying the amount
of twist put into the strands of which the cord is to be formed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The construction of machinery for doubling laying and twisting substantially
as herein before described.
2. The combination of the spindle A disc A¹ bobbins and flyers D positive take
up rollers K, flyer L and bobbin M substantially as hereinbefore described.
3. The arrangement of gearing for giving motion to the spindle A and flyers D
substantially in the manner herein before described.
