JOHN TATHAM of Rochdale in the County of Lancaster, Machine Maker
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING
COTTON WOOL AND OTHER FIBROUS MATERIALS."
My invention relates to improvements in ring and traveller frames for spinning
and doubling cotton wool and other fibrous materials and consists in making and
applying an elongated traveller which when working adjusts itself and yields to
the various diameters of the cop thereby regulating the tension of the thread in
passing to the cop from the traveller round which the yarn or thread is lapped.
I also cause the action of the ring rail on which the ring and traveller works
during its upward and downward motion depositing the thread in an angular
position to make its changes quickly at the point of the cop thereby retaining and
utilizing the impetus given to the traveller when winding on the large diameter
which impetus assists the traveller in winding the yarn or thread at the point of
the cop.
My invention also consists in applying one or more rods or bars capable of being
moved to and fro at intervals behind the spindles and coming in contact with the
yarn or thread as may be desired such rods or bars being suspended in brackets
that can be made in shape and position to regulate the contact of the rods or bars
with the yarn or thread the said rods or bars being caused to move to and fro by
the motion of the copping rail or other convenient and suitable part of the
machine.
My invention consists further in forming the block that winds up the chain
working the ring rail with projections for the purpose of regulating the "cop-
bottoms."

page_text: My invention also relates to arranging the rollers spindles and guide wires to be
used in connection with the above described improvements and consists in placing
the rollers in an inclined position with their front or delivering part as near over
the top of the spindles as the angle of the yarn or thread will allow on its passage
to the spindle without causing it to cease its contact with the guide wires.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Tatham in the Great Seal Patent Office on the 30th July
1883.
JOHN TATHAM of Rochdale in the County of Lancaster Machine Maker
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING
COTTON WOOL AND OTHER FIBROUS MATERIALS.
My Invention relates firstly to Improvements in ring and traveller frames for
spinning and doubling cotton, wool and other fibrous materials and consists firstly
in making and applying an elongated traveller which when working adjusts itself
and yields to the various diameters of the cop thereby regulating the tension of
the yarn or thread in passing to the cop from the traveller round which the yarn
or thread is lapped or wound-In Figs: 1 and 2 of the drawing hereunto annexed
Fig 1 is a section of a ring of a ring spinning frame and Fig: 2 is a plan thereof
The upper portion 6 of the ring a I make much wider than heretofore so that the
parts c. d overhang the part e more than hitherto―The traveller f shown more
clearly in the detached view Fig: 3 is formed of greater length froin g to h than
heretofore so that such traveller f may have a greater amount of movement in the
direction of its length than has hitherto been the case with travellers used in ring
frames Figs 1 and 2 show the position of the traveller f when the yarn is being
wound upon the larger diameter of the cop i in which case the traveller is passing
round the ring a in the direction of the arrow A at its greatest velocity and the
part of the traveller is caused to press against the inner surface of the ring a
around which it travels but when the yarn or thread is being wound upon the
smallest diameter of the cop i and when the ring rail is changing its motion from
ascending to descending the traveller f will take the position shown in Figs: 4
and 5 at which time the tension of the yarn or thread will draw the part f** of
the traveller fagainst the outer surface of the ring a and thereby regulate the
tension of such yarn or thread as it is wound on to the cop i.
The next part of my invention consists in causing the rail carrying the ring and
traveller to make its change at the point or apex of the cop quickly thereby
utilizing the impetus given to the traveller when winding the yarn or thread upon
the large diameter of the cop. Figs 6 and 7 show so much of a ring and traveller
frame as is requisite to illustrate this part of my invention Fig: 6 being a vertical
cross section and Fig: 7 a side view of such frame aforesaid-To corresponding
parts in each of the figures I shall apply similar letters of reference Atk is the

page_text: cam which actuates the ring rail and at m is a frame turning upon a fulcrum n.
Within the frame m is a shaft o fast upon which is a pulley or circular block p
also fast upon the shaft o is a worm wheel q into the teeth of which the worm ?
fast upon the shaft * gears such shaft * being capable of being rotated within
bearings m* upon the frame m. Upon the frame m is mounted a bowl s against
which the circumference of the cam k acts At t is a chain connected at one end
to the pulley p the other end of the said chain t being secured to a pulley t* to
which is secured one end of a chain t** the other end of which is secured to a
pulley u fast upon a shaft carried by suitable bearings Fast upon the shaft v
are pulleys w to the circumference of which is secured one end of each of a number
of chains the other ends thereof being attached to brackets y fast upon the bar
or rod to the upper end of which is secured the ring rail . As the cam k is
rotated in the direction of the arrow B one portion of the circumference of the
said cam acting upon the bowl 8 will cause the ring rail to ascend and another
portion of the circumference of the said cam k regulates the descent of the said
ring rail At such times as the ring rail is ascending the yarn or thread is
being wound upon the cop 1 in a spiral position and during the descent of such
ring rail the yarn or thread is being wound in a quick or open spiral-The
portion C. D. E. of the cam k causes the ring rail to ascend at such speed as to
build the yarn or thread upon the cop in a spiral position and the portion E.
F. C. of the cam allows of the rapid descent of the ring rail by which the yarn
or thread is wound upon the cop in a quick or open spiral For this purpose I
form the portion C. F. E of the circumference of the cam k as shewn in the
drawing so as to allow the descent of the ring rail to take place with great
rapidity so that the yarn or thread will be wound upon the cop 1 at a very con-
siderable angle to the axis of the spindle 2 and in order that such winding of the
yarn or thread upon the cop 1 may take place without injury to such yarn or
thread I employ in conjunction with the form of cam above described the
traveller herein before described in reference to the first part of my invention so
that the impetus imparted to the traveller when the yarn or thread is being
wound upon the larger diameter of the cop 1 maintains the tension of the yarn or
thread when such yarn or thread is being wound at the point of the cop 1
The next part of my invention consists in applying one or more rods or bars
capable of being moved to and fro at intervals behind the spindles and coming in
contact with the yarn or thread as may be desired-To the underside of the part 3
to which the guide wires 4 are jointed I secure at intervals along the length of the
frame by means of bolts and nuts 5 brackets 6. From these brackets 6 depend
levers 7 hinged upon the brackets 6 by means of the pins 8-The levers 7 support
a rod or bar 9 such rod or bar 9 beiug secured to the levers 7 by screwing or in
any other convenient manner The lower parts 7* of the levers 7 rest against the
ring rail so long as the ascending and descending motion of the ring rail acts
upon the levers 7 between the points G and H the said levers 7 will not be moved
thereby but as the building of the cop 1 proceeds the ring rail will arrive against
a portion of the levers 7 between the points H and J and will thereby move such
levers 7 in the direction of the arrow K such movement increasing until upon the
completion of the cop 1 the levers 7 will have been turned into the position shewn
by the dotted lines L-Such movement of the levers 7 in the direction of the
arrow K will as the ring rail ascends carry the rod or bar 9 further from the
spindle 2 so that the yarn or thread in passing from the guide wires to the cop 1
may revolve through a larger circle and also carries the rod or bar 9 clear of the
cop 1 and ring 10 as such cop 1 approaches completion-By the above described
arrangement I obtain a more uniform tension of the yarn or thread and prevent
the extending of the yarn or thread and also prevent the yarn or thread of one cop
coming in contact with the yarn or thread of the next cop
By altering the form of the part of the levers 7 acted upon by the ring rail
any desired amount of motion in the direction of the arrow K can be imparted to
the rod or bar 9-A further part of my invention consists in forming the block or
°

page_text: barrel that winds up the chain working the ring rail with projections for the
purpose of regulating the building of the cop bottoms and is also illustrated by
Figs 6 and 7 of the drawings. At p is the block or barrel upon which the chain t
working the ring rail is wound-The block or barrel p I provide with a projecting
arm 11
As the winding on of the yarn or thread upon the cop 1 proceeds the
frame m is turned upon its fulcrum n By the cam / this turning of the frame m
brings the levers 12 against a fixed part 13 thereby causing the pawl 14 to act
upon the teeth of the ratchet wheel 15 so as to turn such ratchet wheel 15 in the
direction of the arrow M, such turning of the ratchet wheel 15 will by means of
the shaft worm 7 and wheel q cause the block or barrel p to be rotated in the
direction of the arrow N-Such turning of the block or barrel p will cause the
chaint to approach such block or barrel p as shewn in the detached view Fig 8-
in which O indicates the position corresponding to that shown in Fig G and P. Q.
other positions as the chain t approaches the block or barrel p a further rotation of
the block or barrel will carry the arm 11 into such position that the chain t will
arrive in contact with the block or barrel p as at Qafter which the chain t will be
wound around the block or barrel p-During the time the arm 11 is being rotated
from the position O to the position Q the bottom of the cop is being formed and I
am enabled by the above described arrangement to build the bottom of the
cop so that the yarn or thread can be readily unwound therefrom without
undue waste
Although I have above described the block or barrel p as being formed with one
projection 11 only it will be readily understood that such block or barrel p may be
provided with additional projections if desired
My invention also relates to an arrangement of the rollers spindles and guide
wires to be used in connection with the above described improvements and consists
in placing the rollers in an inclined position with their front or delivering part as
。 near over the top of the spindles as the angle of the yarn or thread will allow on
its passage to the spindles without its ceasing to be in contact with the guide
wires At 16 are the rollers carried upon the roller beam 17 such rollers 16 I place
in an inclined position and in such position above the spindles 2 that the yarn or
thread 18 in its passage from the front rollers 16* to the travellers 19 when the
ring rail approaches the top of the spindles 2 shall be nearly a straight line being
only slightly deflected therefrom by resting in contact with the guide wires 4. By
the above arrangement the friction of the yarn or thread 18 upon the guide
wires 4 is reduced thereby enabling the twist imparted to the yarn or thread by
the spindle 2 to more readily pass to the "nip " of the rollers 16* than has
hitherto been the case the inclined position of the rollers 16 also assisting in
permitting the twist imparted to the yarn or thread 18 to pass close up to the
"nip" of the rollers 16*
Having thus described the nature of my said invention and the manner in which
the same is to be performed I desire it to be understood that I claim as secured to
me under the above in part recited Letters Patent
