Improvements in Apparatus Used for Spinning and Doubling Cotton
and other Fibrous Substances.
I JAMES SEED of 4 Avenham Terrace, Preston in the County of Lancaster
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in Ring Frames.
-
The object of the invention is to enable yarn or thread to be spun, or doubled on
the bare spindle, paper tube, or bobbin with greater facility than hitherto.
One of my improvements consists in the application to ring frames of suitable
apparatus for driving them alternately at a high and low speed in the following
manner viz. changing the speed of the ring frame quickly from the high to the low
speed when the ring rail is approaching the nose of the cop, or bobbin spinning at,
and near the nose at the low speed, and returning to the high speed when the ring
rail has receeded a sufficient distance from the nose of the cop or hobbin.
-
When commencing to spin a cop, or bobbin the ring frame is run at the low speed
until the diameter of the cop, or bobbin has increased sufficiently for the full speed to
be used.
For spinning or doubling cops, or bobbins on small diameters my improved
travellers for which a patent is granted dated August 18th 1887 No. 11275 are used
in conjunction with the improvements herein described.
One method of carrying into effect this part of my invention consists in fixing on
the heart shaft of the ring frame an adjustable cam, against this can one end of a lever
is pressed, the other end being near the strap fork having a spring and catch with
On the cylinder shaft
which it may be engaged by a part hinged to the strap fork.
along with the fast and loose pulleys is placed another loose pulley having a small
pinion attached to it, this gears into a larger pinion on a stud having a small pinion
attached to it, which gears into a larger pinion fixed on the cylinder shaft. When the
strap put on the fast pulley the ring frame will run at the high speed, and when put
on the pulley having the pinion attached to it, it will run at the low speed.
Other modifications consist in using suitable grooved pulleys and bands to obtain
the low speed instead of the pinions; or for obtaining both the high and low
speeds.
Another modification consists in moving the driving strap from the fast to the loose
pulley by the mechanism already described; thus allowing the frame to run by its
momentum at a reduced speed when spinning at, or near the nose of the cop, or
bobbin.
By another modification the low speed is obtained by moving the driving strap on
to a clutch pulley, which can be adjusted so that the power communicated to the ring
frame is sufficient to drive it at the low speed.
Another of my improvements consists in the construction of the bolsters of self-
contained ring spindles in suitable parts; whereby the spindle may with facility be
set in a vertical position.
According to one modification the bolster is composed of two parts; the outer part
consists of a short tube and flange, the upper part of which has a hollow spherical part
in it, the bottom having a convex surface, the lower part is provided with a screw,
washer, and nut; the inner part of the bolster has a spherical part on it which fits the
outer spherical part, below this the inner bolster is made of a less diameter than the
inside of the outer tube and projects below the tube, a screw, washer, and nut is pro-
vided with which to secure the inner and outer parts of the bolster when the spindle
has been adjusted to a vertical position.
Various modifications of this improvement may be made in which the construction

page_text: of the bolster is such as to allow of an additional adjustment; whereby the spindle may
he set in a vertical position, or at right angles to the plane of the bolster rail.
Another part of my invention consists in an improved form of break, and holding
down catch for the spindle.
The spindle is provided with a "dog," or projections near the wharve; to the flange
of the holster a projection is attached of such a form, that on the spindle being lifted
up the "dog" comes in contact with the projection; stopping the spindle, and retaining
it at a suitable hight for finding the broken end; the end being found and the yarn
put under the traveller the spindle is pushed down, and thereby liberated.
By another method a disc is formed on the spindle, and on lifting the spindle up,
the disc is scotched by an inclined part attached to the flange of the bolster.
On the break projection, or other suitable position is hinged the holding down catch,
this hangs, or remains in such a position that the spindle is free to be lifted up when
spinning the cop, or bobbin ; and on the ring rail being lowered for the purpose of
doffing, it causes the catch to move, and prevents the spindle being lifted.

COMPLETE SPECIFICATION.
Improvements in Apparatus Used for Spinning and Doubling Cotton
and other Fibrous Substances.
I JAMES SEED of 4 Avenham Terrace Preston in the County of Lancaster
Engineer 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 improvements in Ring Frames.
The object of the invention is to enable yarn, or thread to be spun or doubled on
the bare spindle, paper tube, or bobbin with greater facility than hitherto.
One of my improvements consists in the application to ring frames of suitable
apparatus for driving them alternately at a high and low speed, in the following
manner viz. changing the speed of the ring frame quickly from the high to the low
speed, when the ring rail is approaching the nose of the cop, or bobbin spinning at,
and near the nose at the low speed, and returning to the high speed when the ring
rail has receeded a sufficient distance from the nose of the cop, or bobbin.
When commencing to spin a cop, or bobbin the ring frame is run at the low
speed until the diameter of the cop, or bobbin has increased sufficiently for the
full speed to be used.
For spinning or doubling cops, or bobbins on small diameters my improved
travellers (for which a patent is granted, dated August 18th 1887 No. 11275)
are used in conjunction with the improvements herein described.
One method of carrying into effect this part of my invention, consists in fixing
on the heart shaft of the ring frame an adjustable cam, against this cam one end
of a lever is pressed, the other end being near the strap fork, having a spring
and catch with which it may be engaged by a part hinged to the strap fork.
On the cylinder shaft along with the fast and loose pulleys is placed another
loose pulley having a small pinion attached to it, this gears into a larger pinion
on a stud having a small pinion attached to it, which gears into a larger pinion
fixed on the cylinder shaft.
When the strap is put on the fast pulley the ring frame will run at the high speed,
and when put on the pulley having the pinion attached to it, it will run at the low
speed.
In order that my invention may be clearly understood, I have annexed hereunto
sheets of drawings, and have marked the same with figures and letters of reference
corresponding with those in the following explanation thereof.
Fig. 1 shows an end elevation of part of a ring frame, and Fig. 2 shows a side
clevation of the same, and represent one modification in which grooved pulleys and

page_text: j
n
bands are used to obtain the low speed instead of the pinions; in which a is the heart
shaft on which is fixed an adjustable cam b, against this cam one end of a lever c is
pressed by the weight d, the other end e being near the strap fork having a
spring g, and catch with which it may be engaged by a part i hinged to the strap fork.
On the cylinder shaft ; along with the fast pulley k, and the loose pulley 1, is placed
another loose pulley m having a grooved pulley n attached to it, and also the larger
grooved pulley o fast on the cylinder shaft; is a carrier pulley, and a straining
pulley for the bands working on the pulleys and o. When the driving strap is put
on the fast pulley & the ring frame will run at the high speed, and when put on the
pulley m it will run at the low speed. The adjustable cam consists of three parts,
the centre part 1 is fastened to the shaft a, 2 and 3 being adjusted and fastened by
bolts to 12 governs the time of putting the driving strap on to the fast pulley k,
the shape being such as to cause the driving strap to be moved gradually on to the
fast pulley, and thereby causing a gradual acceleration of the speed of the
ring frame from the low to the high speed; 3 governs the time of putting the
driving strap on the pulley m for obtaining the low speed; it is preferable
to cause the ring rail to ascend quickly from the shoulder to the nose of
the cop, or bobbin and to cause the speed to be reduced quickly when the ring rail is
near the nose of the cop, or bobbin, the shape of the part 3 of the cam being such as
to cause the driving strap to be moved quickly from the pulley k to the pulley m,
which will cause the sudden reduction of the speed from the high to the low speed,
thereby utilizing the high momentum of the traveller to carry it along at the reduced
speed.
;
When the ring frame is required to be stopped, the handler is moved in the direc-
tion shown by the arrow, the projections being moved into the notch t.
When the ring frame is required to be driven at the uniform low speed, the projec-
tion is moved into the notch u.
When the two speeds are required to be used alternately, the projections is placed
in the position shown in Fig. 1, when the catch is moved back by an incline on i
until the spring g forces it into a retaining notch in i.
Another modification consists in moving the driving strap from the fast to the
loose pulley by the mechanism already described; thus allowing the frame to run by
its momentum at a reduced speed when spinning at, or near the nose of the cop, or
bobbin.
Figs. 3 and 4 are plan views (partly in section) of another modification of driving
pulleys of a ring frame, in which the low speed is obtained by moving the driving
strap on to the clutch pulley m, which can be adjusted in Fig. 3 by the position of the
lever in the rack w, so that the power communicated to the ring frame is sufficient
to drive it at the low speed. In place of the rack wa screw may be used to regulate
the position of the lever ; and in Fig. 4 the clutch is adjusted by a screw acting on
the clutch through a spiral spring.
ひ
Fig. shows a side elevation of another modification of pulleys, and clutches,
in which bands are used for obtaining both the high and low speeds; the saine
mechanism as shown in Figs. 1 and 2 being used, the lever x engaging with the
fork which is equivalent to the strap fork in Fig. 1.
When the friction clutch y engages with the ring frame is driven at the high
speed, and when it engages with m at the low speed, and when placed at an
intermediate point between the pulleys & and m the ring frame remains at rest.
By another modification two driving straps may be used, either driven at
different suitable speeds, or driving larger and smaller pulleys on the cylinder
shaft to obtain the low and high speeds.
Various mechanical modifications may be made in the details of construction; so
that the improved driving apparatus may be applied to the various different con-
structions of ring frames.
Another of my improvements consists in the construction of bolsters of self
contained ring spindles in suitable parts; whereby the spindle may with facility
be set in a vertical position.

page_text: Fig. 6 is a side elevation (partly in section) showing one modification of the
adjustable bolster which is composed of two parts, the outer part a consists of a
short tube and flange, the upper part of which has a hollow spherical part in it,
the bottom having a convex surface, the lower part is provided with a screw,
washer, and nut; the inner part of the bolster c has a spherical part on it which
fits the outer spherical part, below this the inner bolster c is made a less diameter
than the inside of the outer tube, and projects below the tube, a screw, washer,
and nut d is provided with which to secure the inner and outer parts of the
bolster, when the spindle has been adjusted to the vertical position.
Fig. 7 shows in section another form of adjustable bolster the footstep a is
adjustable being secured in its position by the nut b. The upper bearing c being
sufficiently large to allow for the requisite lateral movement of the spindle foot.
Fig. 8 shows another form of adjustable bolster, the inner bolster a is held in position
by the part b, secured by the nut c; d is a packing of material sufficiently flexible to
allow the bolster a the required lateral motion for the adjustment.
Fig. 9 shows another form of adjustable bolster, the inner bolster is held at the
upper part in the same manner as Fig. 8; the lower part is held by three
washers b, the centre washer being felt, or cloth, these are secured in position by
the nut c.
Various modifications of this improvement may be made in which the construc-
tion of the bolster is such as to allow of an additional adjustment; whereby the
spindle may be set in a vertical position, or at right angles to the plane of the
bolster rail.
Another part of my invention consists in an improved form of brake, and
holding down catch for the spindles.
Fig. 10 shows one form of brake. The spindle a is provided with a dog," or
projections b, b, to the flange of the bolster a projection c is attached, of such a form
that on the spindle a being lifted up the "dog" comes in contact with the projec-
tion c, stopping the spindle, and retaining it at a suitable height for finding the broken
end; the end being found and the yarn put under the traveller, the spindle is pushed
down and thereby liberated.
The "dog," or projections b, b may be made in one piece from stamped metal, and
driven on the sleeve of the spindle below or above the wharve.
By another method a disc 6 Fig. 11 is formed on the spindle a, and on lifting the
spindle up the disc is scotched by the inclined part c attached to the flange of the bolster.
On the brake projection c as shown in Fig. 11. and applicable to Fig. 10, is hinged
the holding down catch d, this hangs, or remains in such a position that the spindle is
free to be lifted up when spinning the cop, or bobbin; and on the ring rail e being
lowered for the purpose of doffing, a projection f fixed to the ring rail causes the
catch d to move, and prevents the spindle being lifted.
Fig. 12 shows another form of holding down catch, d is a bar placed in front of the
spindles supported by the arm, or arms g, and hinged at h, the centre h being so
situated that on the ring rail e rising, the catch d will fall forward until it has liberated
the spindles; and on the ring rail e being lowered for the purpose of doffing, the pro-
jection, fixed to the ring rail, acts on the inclined part of g, moving the catch d
into the position shown.
Fig. 13 shows another form of the improved holding down catch, behind the spindles
a rod is placed supported in bearings i, to the holding down catch d is fixed behind
each spindle, one or more arms are also fixed to the rod h, on the ring rail e
descending for the purpose of doffing, the projection facts on the incline of the arm j,
causing the catch d to go in the position shown; when the ring rail ascends the
weight k causes the catches to be withdrawn from the spindles.

tion and in what manner the same is to be performed I. declare that what I
claim is :-
First. The apparatus for driving ring frames alternately'at a high and low uniform

page_text: speed; and for gradually accelerating the speed of the ring frame from the low to the
