Improvements in or relating to Spinning Machinery, which are also
applicable to Doubling Machinery.
I, JAMES BUCKLEY, of 37, Adelaide Street, Southport, in the County of Lancaster,
Mill Manager, do hereby declare the nature of my said invention to be as
follows:-
This invention refers to improvements in or relating to machinery, such as, ring
fraines and others for spinning and doubling cotton, wool, and other fibrous materials,
and has for its object the making of firmer and more reliable yarn, free from soft places,
and less waste than hitherto. This invention is equally applicable to machines for
spinning on the bare spindle or bobbin. To effect this I attach a motion to give
movement to the roller part and cop motion of the machine, which consists of a
wheel provided with a slot in which is mounted a diamond or block prepared to
receive a stud. The latter is fixed in a wheel which I term the stud wheel. The
before mentioned slotted wheel and the stud wheel work concentric to each other at
the commencement of the cops when the spindles are bare. The stud wheel is fixed
on a sliding bar attached to a regulator, the latter operating the stud wheel to place
it in an eccentric position to the slot wheel until the cop has arrived at the thickness
or the cop bottom is formed. This apparatus will effect a more regular twist and
more uniform yaru than hitherto, giving the same number of revolutions to the
traveller both at the thickness and at the cop nose. To facilitate lubricating of the
spindles each footstep is provided with means for receiving lubricant on its front
side.

1, JAMES BUCKLEY, of 37, Adelaide Street, Southport, in the County of Lancaster,
Mill Manager, do hereby declare the nature of my said invention and in what manner
[Price 8d.]

page_text: sliding bar 35 mounted in the slide fixing 36 secured to the frame end 1. The sliding
parts of the catch-boxes 32 and 33 are driven by the keys or feathers 37 on the shaft 7.
This invention operates in the following manner :- When the machine or frame is
set in motion on the commencement of the formation of the cops and when the
spindles or bobbins are bare the slotted wheel 10 and the stud wheel 14 are concentric
to each other, as shown in Figs. 1 to 4 inclusive, and the catch-box 32 is in gear
as shown in Fig. 5. The spur pinion 31 has one, or more, tooth or cog less than
the spur pinion 31* for the purpose of reducing the speed of the rollers 5 when
commencing to spin on the bare spindle to prevent soft yarn. The catch-box 32
is held in position by the pin 38 mounted in the slide fixing 36. The pin 38
drops into a notch in the edge of the sliding bar 35, by which it is held until
a sufficient portion of the cop has been spun. When the shaft 7 is rotated to
drive the machine or frame the pinions 31, 30, 28, 27, and 26 24 are operated to drive
the stud wheel 14 which drives the slot wheel 10 by means of the stud 13 and diamond
or block 12 in the slot 11. The rotating of the slot wheel 10 operates the
shaft 9 and worin 39; the latter gearing into the worm wheel 40 on the shaft 41 in
the fixings or bearings 42. On the shaft 41 is fixed the worm 43 gearing into the
worm wheel 44 on the shaft 45. The shaft 45 is mounted in the bearings 46, and is
fitted with the bevel wheel 47 gearing into the bevel wheel 48 on the spindle 22, by
which the latter is driven to regulate the position of the stud wheel 14 and place it
gradually in an eccentric position to the slot wheel 10 until the cop has arrived at the
desired thickness or the cop bottom has been formed. When the latter has been
performed the worm wheel 44 will have been rotated to bring the part devoid of
teeth shown in Fig. 4-under the worm 43, by which the regulation of the stud
wheel 14 will cease. The shaft 45 is provided with the key or feather 49 to allow of
the worm wheel 44 being slid out of gear for the purpose of re-setting the stud
wheel 14 into a concentric position with the slot wheel 10 when desired for.the next
set of cops.
When the cop bottom is about half formed it is desirous to increase the
speed of delivery of yarn owing to the diameter of the cop bottom being increased.
The pivoted lever 51 is operated by the cain 50 on the shaft 41, which lifts the pin
38 from the sliding frame 36 by means of the chain 52 attached to the pin 53 on the
pivoted lever 51. Immediately the slide bar 35 is released from the pin 38 it is slid
by the spring 54 in such a manner as to pull the catch-box 32 out of gear with the
pinion 31, and put the clutch-box 33 in gear with the pinion 31%, which it will be
remembered is provided with one or more tooth or teeth more than the pinion 31, and
the clutch box 33 remains in gear with the pinion 31 at-which-point-it-remains until
the cops completed. It will be understood from the foregoing description that
although the slot wheel 10 revolves upon the fixed stud 9 yet the stud wheel 14 carrying
the radial arm 16 by which the slot wheel 10 is driven has been gradually shifted during
the formation of the cop bottom from a concentric to an eccentric position relative to the
slot wheel 10. Therefore as the stud wheel 14 revolves eccentrically to the slot wheel 10
the sliding of the diamond or block 12 within the slot 11 creates a differential speed of
the slot wheel 10 although the speed of the stud wheel 14 is constant. The maximum
speed of the slot wheel 10 is attained when the block 12 is moved by the stud whe-l 14 to
the position in the slot 11 nearest to the centre of the slot wheel 10 and gradually
approaches its minimum as the block.12 is moved outwards towards the periphery of the
slot wheel 10. The drawing rollers 5 are driven from the slot wheel 10 and therefore
receive a variable speed. This variable speed is arranged to be commenced at a maxi-
mun when commencing the "chase" of the cop and is gradually reduced to a minimum
when winding on the bare spindle at the end of the chase. The drawing rollers there-
fore deliver the greatest amount of yarn at the time when it is required viz. when wind-
ing on the thickest portion of the cop, gradually reducing the supply of yarn as
the bure spindle is approached. The apparatus thus effects a more regular twist
resulting in more uniform yarn giving the same number of turns or twist to the
yarn per inch both at the thickest and at any other point of the chase. The
rollers 5 are driven from the slotted wheel 10 by the pinions 55, 56, and 57, by
which the yarn is delivered in proportion to the diameter of the building up of the
cop

page_text: The copping motion is operated and regulated by the movements of the slot wheel 10
on the shaft or centre 9. On the latter is mounted the bevel wheel 58 gearing into
the bevel wheel 59 on the shaft 60. The latter is held or supported in suitable
bearings (not shown) and is fitted at its lower end with the bevel wheel 61 gearing
into the bevel wheel 62 on the heart cam shaft 63. To-assimilate-the-winding of the
ring-frame to that-of-the-mule-and-by-which-the-cop-nose-is-less liable-to-pull to
waste-I-provide-in-conjunction-with-the-ordinary-bowl-two-n die-or-dies 65 to work
with-the-heart-emm-64-as shown-in-Figs. 7 and & by which the same will reduce
friction-and-allow-of-n-speedy-change-when-winding-on-cop-nose. The--dies--66--are
mounted-on-the-lever-66-on-ench-side-of-the-ordinary bowl-67. The heart-cam-64-is
increased-in thickness-at-the-end-to operate on the dies-to, but is of the ordinary
thickness-in-the-remaining part-to-operate on-the-bowl-67. The lever 66 is connected
to the pulley-68 on-the-shaft-60-by-the-chains 70. The shaft-60-is-supported-in-the
bearings-71 attached-to-the-frame-end-1.—On the shaft 60 is fixed the pulley-72-to
which is-secured the chain 73 to connect-it-with the quadrant-74-on-the-shaft-75.
The shaft 75 is fitted with the lever-76, to which is pivoted the upright-77 secured to
the-copping rail 2. The upright-77 is momnited in the bearing 78-in the holster
rail 3. This arrangement of-mechanism-operated-from the slot wheel-10 produces
winding-on-the-cop-nose when-travelling-downwards-no-shown in Fig. 1) and is a fue
simile of that-produced-on-the-ordinary spinning mule.
To prevent-waste of yarn when " doffing" the ordinary guide board is replaced by
the-hinged guide boards 70 secured to the brackets SO-and shaft &t. When the cops
are pushed upon-the-spindle, as shown in Fig. 9, for the purpose of doffing," the
guide-bourds-70-are-dropped, as shown in dotted lines, and the-ring-or copping rail-2
is also dropped-to-allow-of-the-overhanging-yarn-$2 being wound on the bare spindle
rendy for the-next-cop. The overhanging-varn, caused by dropping the yarn guides,
is wound-on-the-bare spindles by turning the driving shift 7 by means of the hand
wheel $3-mounted thereon. The yarn-guides or boards-70-are-made-in hinged form
as shown-in-Figs. 10-and-11,-to-allow-of-the-upper or-front-part being raised when
desired-or-necessary. The front part is secured to the back-part by the pine 24, and
is held in position when spinning is being performed by the lock bolt Sa--and
spring 26. The latter allows of the lock-bolt es being pressed back when the
lowering-of-the-front part is necessary.
To prevent the travellers on the rings operating when the nucleus of yarn is being
wound-outo-the-bare spindle-by-turning the hand wheel-83, 1-mount-under-the- ring
or copping mail 2-the-shaft-87;-on which are mounted; opposite-ench ring and
traveller,-the-fingers 88, which can be dropped into the path of each-traveller, s
shown in Fig-0. When-sufficient yarn has been wound-on-the-bure-spindles or
bobbins-by hand the fingers 22-are-placed-in-the-position-shown in dotted lines by
the-handle & to allow of their operation when the machine-or-frame-is set in motion.
By this arrangement-no-yarn is cut to waste-us is usual in ring spinning frames.
To facilitate lubrienting of the spindles 00-1-attach my improved footstep 01 to the
footstep-rail. This-footstep is constructed as shown in Figs. 12 and 13 to allow of
the same being supplied with lubricant on the front-side 02. It-can-be-made-in
continuous-lengths-with-several footsteps in each portion, or separately as desired,
and-is-provided-with-the-cover 03.
The heart cam 64 engages with the ordinary bowl 67 carried in bearings in the copping
lever 66. The lever 66 is connected to the pulley 68 on the shaft 69 by the chain 70. The
shaft 69 is supported in bearings 71 attached to the frame end 1. On the shaft 69 is
fixed the pulley 72 to which is secured the chain 73 to connect it with the quadrant 74 on
the shaft 75. The shaft 75 is fitted with the lever 76 which supports the upright77 secured
to the ring rail 2. The upright 77 is mounted in the bearing 78 in the bolster rail 3.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a ring spinning frame, the method of converting a positive motion to a
