Improvements in Spinning Yarn from Cotton and other Fibrous
Substances, and in Apparatus therefor.
We JONATHAN BOWDEN of No. 252 Rochdale Road, Carriers' Agent, and JOHN
WALKER of 4 Franklin Street Machinist both of Oldham in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:—
This invention relates to a new method of and apparatus for spinning and doubling
yarns made from cotton and other fibres.
The improved apparatus is constructed as follows: On a frame of suitable form
we arrange the usual drawing rollers and stand as in the mule, throstle or ring
spinning frame, and place them in about the ordinary position.
At a convenient distance from the rollers we place a right angled beam or rail on
which, at the ends, and at other convenient poinis, are fixed vertical slides.
These slides run in grooves formed in or on the frame side and at other requisite
points, and fixed to the back of the beam are projecting arms carrying bearings in
which revolves a shaft fitted with a tin drum.
Along the front of this beam and at regular distances apart according to
requirements are mounted bearings in which revolve a series of metal discs which
work in a vertical axis and are each provided beneath with a grooved band
pulley by means of which they are driven by bands from the tin drum at the other
side of the beam.
The discs are bored through the centre and on the top of each is an upright
projection with a curl for the yarn to pass through, this is made of sufficient length
to make a cop as required.
Under this beam (which we name the disc-beam) we place a horizontal spindle
rail which is also mounted in vertical slides and provided with racks and wheels to
work it up and down, and this spindle rail is balanced by weights and chains hung
over pulleys.
In the spindle rail, at exactly the same distances apart as the discs are, and
directly under each one, there is a bearing and footstep for the spindle to work in.
The spindles are fixed vertically in this rail and pass through the centres of the
discs above.
Behind the roller stand in a convenient position is fixed the driving shaft on
which is keyed a spur wheel driving one of half its size on another shaft on which
there is a spur wheel driving a smaller spur wheel which is fixed or cast to a bevel
wheel revolving on the first driving shaft.
From the driving shaft to the tin drum shaft on the disc beam is fixed a swing
bracket and in this bracket are bearings supporting a shaft which is driven by the
aforesaid bevil wheel on the driving shaft and works the tin drum shaft. There is
a provision made for changing the wheels so as to obtain any number of revolutions
required for the speed of the discs.
On the driving shaft is another spur wheel driving a second motion shaft at a
suitable speed and on this shaft is an elliptical wheel driving a similar wheel on a
counter shaft (No. 1) and on this shaft is a heart shaped tappet or cam (eithe
external or internal) which works a lever swung in the centre and fixed with one
end carrying a bowl under the cam, and the other end under a bracket on the disc
beam so as to give a rising and falling motion thereto.
From this it will be seen that the cop is built on the bare spindle, and from the
disc beam falling and rising slowly from the bottom centre, and the rollers
delivering more yarn from the quick motion, the enlarged diameter of the co
bottom is minde and rice versu towards the top.

page_text: The spindle rail is worked by a pawl and ratchet wheel from the heart wheel
levers and falls in its slides gradually as the yarn is spun on the spindles. A handle
is fitted for raising the spindle rail to re-start spinning a fresh set of cops, and a
lever is worked from the spindle rail for giving the required diameter of cop.

COMPLETE SPECIFICATION.
Improvements in Spinning Yarn from Cotton and other Fibrous
Substances, and in Apparatus therefor.
We JONATHAN BOWDEN of No. 252 Rochdale Road Carriers' Agent, and JoHN
WALKER of 4 Franklin Street Machinist both of Oldham 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 :-
This invention relates to a new method of and apparatus for spinning and doubling
yarns made from cotton aud other fibres.
The objects of the invention are to simplify improve and economize the
construction and working of the apparatus and to produce a more even yarn than
heretofore at a reduced expense.
The nature of the said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the two sheets of drawings hereunto annexed and the following explanation thereof.
Figs. 1 and 2 on Sheet 1 of the drawings are vertical transverse sections of so
much of the improved spinning and doubling frame as is necessary to illustrate the
invention and Figs. 3 and 4 are corresponding partial plan views.
On Sheet 2 of the drawings Fig. 5 is a partial front elevation Fig. 6 a partial
end view and Fig. 7 a partial plan view showing more particularly parts of the frame
which are not shown on the other views in order to avoid confusion.
The improved apparatus is constructed as follows: On a frame a of suitable form
we arrange the usual creel b, drawing rollers and stand e as in the mule, throstle, or
ring spinning frame, placing them in about the ordinary positions.
At a convenient distance from the rollers we place a right angled beam or
rail d on which, at the ends and at other convenient points are fixed vertical
slides e.
These slides e work in grooves formed in or on the frame side and other
requisite points, and fixed to the back of the beam d are projecting arms 9 carrying
bearings in which revolves a shaft / fitted with a tin drum i.
Along the front of the beam d and at regular distances according to the require-
ments, holes are drilled and fitted if necessary with bushes, or bearings are provided
in which revolve a series of metal discs which work on a vertical axis and are
each provided beneath with a grooved band pulley by means of which they are
l
driven by endless bands from the tin drum i at the other side of the beam d, or,
instead of a tin drum and band, the shaft may be placed in such a position as to
drive the discs by means of skew toothed gearing, when required for spinning or
doubling heavy fibres.
The discs are bored through the centre, and on the top of each is an upright
arm or projection me with a curl at the top for the yarn to pass through; this is
made a sufficient length to make a cop as required.
Under the beam d (which we name the "disc-beam") we place a horizontal
double spindle rail n which is also mounted in vertical slides and is provided with
racks o and wheels p to work it up and down and this double spindle rail n is
balanced by weights and chains q hung over pulleys as seen at Fig. 1.
In the spindle ail n at exactly the same distance apart as the discs k are, and

page_text: directly under each one of the latter there is a bearing and footstep for a spindle -
to work in. The spindles are fixed vertically in the rail n and pass through the
centres of the discs & above (see Figs. 12 and 5).
Behind the roller stand c in a convenient position is fixed the principal driving
shaft & on which is keyed a spur wheel (Fig. 3) driving a similar wheel " of
smaller diameter on another shaft on which there is a spur wheel w driving a
smaller spur wheel a which is fixed or cast to a bevil wheel y revolving loose on the
principal driving shafts and gearing with a bevil pinion z.
From the principal driving shafts to the tin drum shaft i on the disc beam d is
fixed an arm or swing bracket in or on which are bearings supporting a shaft 2
which is driven by the aforesaid bevil wheel y and pinion z and works the tin roller
shaft i by the bevil wheel 3. There is a provision made for changing the wheels 3
so as to obtain any number of revolutions required for the speed of the discs.
On the driving shaft s is also keyed a spur pinion 4 (see Figs. 2 and 3) driving a
second motion shaft 5 at a suitable speed by a wheel and on this shaft 5 is an
excentric wheel 7 (Figs. 2 and 4) driving a similar wheel 8 on the first countershaft 9
and on this shaft is a heart shaped tappet or cam 10 (either external as shown or
internal) which works a lever 11 swung at its centre and having a bowl at one end
under the cam 10 and the reverse end working under a bowl carried by a bracket 12
attached to the disc-beam so as to give a varying rising and falling motion
thereto.
On the second motion shaft 5 is another excentric wheel 13 driving a similar
wheel 14 on the second countershaft 15 and on this is keyed a spur wheel 16 driving
a lower shaft 17 by a pinion 18.
On one end of this lower shaft 17 is a bevil wineel 19 (see Figs. 4, 5 and 6) driving
by means of a smaller bevil-wheel 20 the diagonal shaft 21 which actuates the
rollers c by means of the mitre wheels 22.
The rack wheels p for actuating the spindle rail n before mentioned are driven in
the following manner.
To the lever 11 (see Fig. 2) is attached a chain 23 passing over a pulley and
having its other end connected to an arm 24 which carries a pawl 25 acting on a
ratchet wheel 26 (see also Figs. 6 and 7) which is connected by a train of gearing 27
to the rack wheel p. 28 is a lever fixed on a stud at one end and extending outside
in front of the machine where it is formed in the shape of a handle. On this lever
is an adjustable bracket 29 which supports the arm 2+ carrying the pawl. And near
the front of the machine is another adjustable bracket 30 upon which the lever 28
rests and when in this position the left hand side of the chain 23 is slack at first and a
certain amount of lift is thus lost. On the rack o of the spindle rail is fixed an
adjustable plate 31 with an incline on the side next the lever (see Fig. 5) and
therefore as the spindle rail n descends the incline 31 pushes the lever 28 off the
rest or bracket 30 and the pawl and ratchet give more lift as required.
The yarn of cotton or other fibre passes from the drawing rollers c to a curl or
guide 32 (Fig. 2) fixed on the disc beam d over the centre of each spindler to the
curl m on the disc & and through the latter to the spindle r or onto a bobbin or
tube.
The disc being driven as before stated by a band from the tin drum revolves
carrying the yarn with it, and thus puts in a turn or twist at every revolution of the
disc, and the yarn being carried round by the disc drags the spindler round with it
and causes that to revolve also so long as it is kept held hard by the yarn, and as
the yarn is eased by the delivery of the drawing rollers c it becomes wound on the
bare spindle, and the disc & being raised and lowered by the heart wheel or cam 10
the yarn is correspondingly placed on the spindle by the curl m on the disc.
The excentric wheels 7 and 8 on the second motion shaft 5 and the first counter-
shaft 9 cause the heart wheel or cam 10 to have an alternate quick and slow speed
in revolving.
The heart wheel or cam 10 is so fixed on its shaft 9 that while its smaller radius is

page_text: in contact with the bowl the disc beam d is at the bottom of its slide and vice versa
at the larger or quick speed radius.
The second pair of excentric wheels 13 and 14 and the second countershaft 15 are
geared opposite to those 7 and 8 of the first countershaft. 9 so that the rollers c are
going contrary to the slide, that is to say, the rollers c are revolving at quick speed
when the disc beam d is at the bottom of the slide, and vice versa when it is at the
top.
From this it will be evident that the cop is built upon the bare spindle and owing
to the disc beam & falling and rising slowly from the bottom centre and the rollers
delivering more yarn owing to their quick motion, the enlarged diameter of the
bottom is obtained, and rice versa towards the top.
cop
The spindle rail n being worked, as before described by the pawl and ratchet
wheel from the heart cam lever 11. falls in its slides gradually as the yarn is spun
on the spindles, and the spindle rail is raised again to re-start spinning a fresh set
of cops, by means of a handle placed on the squared end 33 of the spindle of one of
the train of wheels 27 (see Fig. 7).
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same to be performed we declare that what we
claim is-
The improved method of and apparatus for spinning and doubling cotton and
other yarns on the bare spindle in the form of a cop substantially as hereinbefore
described and illustrated by the drawings annexed.
