SAMUEL BROOKS, of the Union Lion Works, West Gorton, Manchester, Machine
Maker, and GEORGE HARRISON, of the same Placo, Manager CERTAIN IMPROVE-
MENTS IN MACHINERY FOR SPINNING AND DOUBLING"
Our Invention is applicable to the machines for spinning and doubling known
as the ring and traveller frames, and it consists, -
Fust In an improved arrangement of parts for doffing the full bobbins or
spools
And, secondly. In an improved apparatus for removing the loose fibres from
the travellers
In our improved 11ng and traveller frames we prefer to wind the yarn on a spool
with a small bottom flange in which is a cross groove fitting on a feather on the
braid fixed to the spindle, other shaped spools or bobbins may be used When the
spool is filled with yain the copping rail is lowered to the bottom of the spool, and
a few coils of yarn are wound above the bottom flange to tie the yarn on the spool,
the frame is then stopped, and the attendant lowers the copping rail until the
travellers are in line with the bosses of the braids, the frame is then started to wind
a few coils of yarn on the said bosses to secure the connection between the delivering
rollers and the spindles, the fiame is again stopped, and the copping rail is then
raised to its starting point, the full spools are now ready to be doffed, and in lift-
ing each spool off its spindle the yarn is broken or cut between the spool and the
boss of the braid, the empty spools are then put on the spindles and the frame is
again ready for starting All these operations can be performed without dis-
connecting any part of the copping motion, excepting that the attendant has to dis-
engage a tumbler catch when the copping rail is lowered, this tumbler catch takes

the Provisional Specification of Letters Patent applied for by us on the 30th day of
November, 1876, No 4635, and to put the said tumbler catch in gear again when
the copping 1ail is lifted to its starting point
Our improved apparatus foi removing the loose fibies from the travellers consists
of an adjustable horizontal stud fitting in a boss fixed to the copping rail, the end of
this stud is set to the proper distance from the traveller by means of a set sciew, or
instead of the stud and set screw the end of a set screw may be brought to act on
the fibres carried round by the traveller

Maker, and GEORGE HARRISON, of the same Placo, Manager "CERTAIN IMPROVE-
MENTS IN MACHINERY FOR SPINNING AND DOUBLING."
Our Invention is applicable to the machines for spinning and doubling known as
the ring and traveller frames, and it consists,-
First In an improved arrangement of parts for doffing the full bobbins or
spools
And, secondly In an improved apparatus for removing the loose fibres from the
travelleis
•
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Diawings, in
which Fig 11s an elevation, and Fig 2 a front view of part of an ordinary ing and
traveller spinning or doubling frame to which our improvements are applied
a, a, are the spindles, which are supported as usual in bolsters and footsteps fixed
in the holster and footstep rails, a¹ aie the spools shewn with the spindle a, detached
in Fig 3, the bottom flange of the spool bears upon the braid a², see Fig 4, fixed to
the spindle, the flange is provided with a cross groove fitting on a feather on the
braid, b, b, are the ing and traveller, or copping rails, ff, are the lifting shafts
which are united by the chamn g passing around the pulleys f¹, and fare the
pulleys for the chains f³, connected below to the cross ail h, which supports the
ends of the "pokers", the upper ends of the pokers are fixed to the rails b The
heartfixed on the shaft acts on a bowl in the lever h, at the end of which is a
stud on which is mounted the ratchet wheel 12, and at every depression of the
lever by the revolving of the heart the ratchet wheel comes in contact with
and is turned partly round by the tumbler catch p, which is hinged to a bracket
fixed to the flaming When the level 11ses after it has been depressed the ratchet
wheel lifts the tumbler catch, which iegans its horizontal position when the ratchet
wheel has passed To the boss of this ratchet wheel is cast or fixed the spui
pinion, winch gears into the change wheel fixed to the end of a short shaft
which revolves in bearings in the level To the shait is fixed a woim z² geal-
ing into the wheel m¹ fixed on the short cross shaft m, which also revolves in bear-
ings in the lever /
To the shaft m is also fixed the cam m², which is connected to
the pulley on the right hand lifter shaft f by the chain m³ The parts above
referred to, excepting the braids a², are made partly as usual, and partly as described
in the Specification of former Letters Patent granted to us on the 30th day of
November, 1876, No 4635
On referring to Fig 3 it will be seen that the holster o projects upwards from the
bolster rail n, and that the braid a² is recessed to pass over the upper end of the
bolster, the object of this is to give a better support to the spindle a and to prevent
or reduce vibration. The under side of the shoulder of the braid a² is made with

page_text: fine teeth or corrugations to assist in breaking the yain when the full bobbins or
spools are doffed, and at the bottom of the braid is a shoulder to prevent the yain
slipping on to the bolster, and in this shoulder are notches to enable the yarn to be
cut off the braid To the cam m³ is fixed a finger m', and to the lever is fixed the
semaphore k, the object of which is to indicate to the attendant when the ring and
traveller rail has been lifted to the proper height for commencing a fresh set of
spools
The mode of operation is as follows -When the spools are filled with yarn the
copping rail is lowered to the bottom of the spools as shewn on the right hand
spindle of Fig 1, and a few coils of yarn are wound above the bottom flange of the
spool to tie the yarn on the spool and to prevent it unwinding when the spools are
doffed, the frame is then stopped, and the attendant lowers the copping rail b by
turning the pinion in the proper direction for moving the cam m² in the direction
of the arrow in Fig 1 until the travellers are in line with the bosses of the braids a²
as shewn at the left-hand side of Fig 1, the frame is then started to wind a few
coils of yarn on the said bosses to secure the connection between the delivering
rollers and the spindles, the fiame is again stopped, and the copping rail is then
1aised to its starting point by turning the handle on the boss of the pinion ³ in the
contrary direction until the finger m³ on the cam m² comes opposite the semaphore k';
the full spools are now ready to be doffed, and in lifting each spool off its spindle
the yarn is bioken or cut between the spool and the boss of the braid, the empty
spools are then put on the spindles, and the fiame 18 again ready for starting All
these operations can be performed without disconnecting any part of the copping
motion, excepting that the attendant has to disengage the tumbler catch p when
the copping rail is lowered, this tumble catch takes into the ratchet wheel k³, for in-
ing part of the improved copping motion described in the Specification of Letters
Patent granted to us on the 30th day of November, 1876, Number 4635, and to
put the said tumbler catch in gear again when the copping rail is lifted to its start-
ing point
Our improved apparatus for removing the loose fibres from the travellers is
shown in elevation in Fig 5, and in plan in Fig 6, and it consists of an adjustable
horizontal stud fitting in a boss in the bai y fixed to the back of the copping rail,
the end of this stud is set to the proper distance from the traveller by means of a
set screw, or instead of the stud and set screw the end of the set screw Z may be
brought to act on the fibres called 1ound by the traveller
Having thus stated the nature of our Invention, and described the manner of
performing the same, we declare that we claim
-
Fust Securing the yarn to the bottom of the spools when full by winding a few
coils thereon, in the manner and for the purpose desciihed
Secondly Recessing the braid to adimit the upper end of the bolster, in the
manner and for the purpose described
Thirdly The apparatus described, consisting of the finger m' on the cam m³, and
the semaphore for indicating when the ring and traveller rail is in the position
for starting, respective of the position of the heart 1'
And, fourthly The apparatus shown and described in reference to Figs 5 and 6
for removing the loose fibres from the travellers
In witness whereof, 1, the said Samuel Brooks, for myself and on behalf of
the said George Harrison, have hereunto set my hand and seal this
