Improvements Appertaining to Spinning and Twisting Machinery
used in the Production of Yarns or Threads of Fibrous Substances.
We, ISAAC BAILEY, of Mornington Street, Keighley, in the County of York,
Gentleman, and ISAAC HENRY WRIGHT, of 15, Gladstone Street, Keighley afore-
said, Engineer, do hereby declare the nature of this invention to be as follows,
that is to say:
"
"
"
It relates to improvements appertaining to machinery for the production of
yarns or threads of fibrous substances particularly of the class known as flyer'
and "cap" spinning and twisting frames and cousists in the application of means
constructed and arranged in such a manner that the process known as doffing
or in other words the process of displacing the bobbins upon which the desired
quantity of yarn has been wound by empty bobbins or those upon which is it
desired to further wind the yarn, may be effected on all the series of bobbins
simultaneously and that by mechanism which is simple of construction and not
so liable to become disarranged as are the devices heretofore employed.
In carrying our invention into effect in connection with those machines known
as flyer spinning and twisting frames we arrange the bottom rail which sup-
ports the machine's spindles and which may be styled the step-rail, to be movable
in a vertical direction, its movement being effected by any cam, worm wheel
or rack and pinion mechanism operated by a hand lever or winch device arranged
as may be found desirable..
In suitable proximity with the upper parts of the spindles where the bobbins
are mounted upon them, and well within the ordinary framework of the machine
we mount another rail having laterally projecting arms formed to receive and sup-
port a series of empty bobbins corresponding in number to the series of spindles
the full bobbins on which they have to displace.
Above this rail which may be termed the bobbin rail we mount another rail
formed to lay-hold-of of the flyers on the spindles when brought into position for
this purpose, appropriate lever and other devices being employed for operating
the said "bobbin rail" and flyer rail as may be found necessary, both said
rails being mounted in bearings to enable or allow such movement in the desired
directions.
"
When the bobbins in the machine have received their proper quantity of yarn
a rail h, to which are attached a number of projecting arms or supporting pieces h³
and it is desired to displace them, the "flyer rail" is brought into position to
hold them against the backward rotation of their spindles (such rotation being
effected by any of the well known devices) thus they are freed therefrom to allow
the spindles to descend on the lowering of the step rail.
When the spindles have thus descended all their respective bobbins will have been
received and left deposited upon the ordinary lifter rail in the machine, so that
on the advancing of the bobbin-rail with its supply of empty bobbins, these latter
are made to push the former from their position on said lifter rail to fall into a
hopper or shoot to be carried away, while the empty bobbins will have been placed
Drine 17

page_text: in position thereon to receive the spindles on these latter being raised to their
operating position, at which time also the flyers will be placed on said spindles
and by the employment of any of the well known devices the whole series of
threads will be twisted or wound for a few revolutions around said empty bobbins,
thus preparing the whole ready to recommence their actions.
To attain the object of our said invention in connection with those machines
known as 66
cap" spinning and twisting frames we arrange the rail which carries
the spindles to be movable in a vertical direction such movement being effected
by any appropriate devices, and also employ a horizontal rail capable of being
moved in a vertical and lateral direction by any suitable means, said horizontal
rail having a series of upwardly extending arms mounted thereon to which are
attached suitable holders for carrying or supporting the empty bobbins.
When it is desired to replace the full bobbins by the said empty ones, the
former are lowered by means of the spindle rail into the desired position where
they are held by any suitable clip or other device, the spindles being further
lowered so as to pass entirely through and below said bobbins. The said hori-
zontal rail with its supply of empty bobbins is then moved so that the latter come
into contact with and displace the full bobbins, which fall into a receptacle at
the front of the machine, while the said empty bobbins will at this time have
been carried into position over said spindles. Mounted on another horizontal
rail and occupying a position between the bottoms of the caps and the upper ends
of the empty bobbins when these latter are in their bottom positions are suitably
shaped hooked parts, said horizontal rail having motion imparted to it at the
requisite time so as to cause said hooked parts to lay-hold-of the threads or yarns
and wrap them a few times around their respective empty bobbins for purposes
well known. The spindle rail is now raised so that the spindles pass through
said empty bobbins and the horizontal rail carrying the holders for said empty
bobbins is made to recede, thus leaving these latter in their proper position on
their spindles and ready for the machine to be started. The full bobbins are
held in the above mentioned receptacle against rotation by any suitable means
such as by a weighted rod, so that on the machine being set in motion, all the
yarns or threads in the series will be broken.
The caps are held from descending along with the spindles when these latter
are lowered, by means of suitably formed supporting pieces mounted upon another
horizontal rail which can be moved in a lateral direction by any appropriate
device, said supporting pieces being provided with appropriately shaped fingers
for taking within notches or openings formed in said caps when said rail or bar
is moved towards the spindles.

We, ISAAC BAILEY, of Mornington Street, Keighley, in the County of York,
Gentleman, and ISAAC HENRY WRIGHT, of 15, Gladstone Street, Keighley afore-
Baid, Engineer, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say:-

It relates to improvements appertaining to machinery for the production of
yarns or threads of fibrous substances particularly of the class known as "flyer"
and "cap" spinning and twisting frames and consists in the application of means
constructed and arranged in such a manner that the process known as doffing
or in other words the process of displacing the bobbins upon which the desired
quantity of yarn has been wound by empty bobbins or those upon which it is
desired to further wind the yarn, may be effected on all the series of bobbins
simultaneously and that by mechanism which is simple of construction and not
so liable to become disarranged as are the devices heretofore employed.
In order that our said invention may be readily understood, we have hereunto
appended sheets of drawings illustrative thereof, to which, by figures and letters,
reference is made in the following description.

are applied.
Figure 8 represents a front elevation of parts shown by Figure 7.
Figure 9 is a drawing in detail hereinafter referred to. Similar letters and
figures of reference indicate similar parts throughout the several views.
In carrying our invention into effect, in connection with those machines known
as "flyer" spinning and twisting frames, such as are illustrated by Figures 1
and 2 of the accompanying drawings, we arrange the rail a which supports the
machine's spindles b, and which may be styled the step-rail, to be movable in a
vertical direction, its movement preferably being effected by the pinion e gearing
with the rack c¹ sliding in suitable bearings on the framework A of the machine,
said pinion being mounted on the shaft d operated by the hand wheel d¹, although
this vertical movement of the step-rail a may be effected by any other suitable
means.
In suitable proximity with the upper parts 61 of the spindles b, and well within
the ordinary framework A of the machine, we mount another rail e, this being
provided with laterally projecting arms or clips et formed to receive and support
à series of empty bobbins f corresponding in number to the series of spindles the
full bobbins on which they have to displace. The rail e is carried by a number
of blocks which are capable of being moved along the bars or levers f6 (only
one of such blocks e² and levers f6 being shown in the drawings, although there
are several throughout the full length of the frame) such movement being obtained
by means of the chains g, chain wheels g', g², shaft g³, worm wheel g', and worm 95
mounted on the shaft 96, the latter being rotated by the hand wheel g7, while the
bars or levers f are movable around the fulcrum g³, and are operated through
the lever arms f², eccentrics f³, shaft f and lever f³.
Above the rail e which may be termed the bobbin rail we mount another rail h
on which is hinged the board h¹ the latter having mounted thereon the arms or
spring holders h² the notches h³ in which lay-hold-of the arms of the flyers k
when the rail is moved to its forward position or the one opposite to that illus-
trated by Figure 1, the movement along the slot h* in the bracket 75 being effected

page_text: by means of the lever he mounted on the rod h, and the links or connecting
rods h8.
When the bobbins f¹ have received their proper quantity of yarn. and it is
desired to displace them, they are raised to their highest position by means of the
lifter rail in the well known manner, and the "flyer rail" h is moved so that
the clips h lay-hold-of the arms 2 of the flyers and hold them against the back-
ward rotation of their spindles, the flyers being first loosened from their spindles
by means of the bar a, projections on which come into contact with and move
the pegs on plates fixed to the spindles b, so as to move said spindles in
a backward direction, after which the spindles are further rotated in the same
direction by any of the well known means, thus the flyers k are freed therefrom
to allow the spindles 6 to descend on the lowering of the step or spindle rail a.
The movement of the rail or bar may be effected by means of the screw a work-
ing in a nut and operated by the hand wheel
When the spindles have thus descended, all their respective bobbins will have
been received and left deposited upon the lifter rail ³, so that on the advancing
of the bobbin rail e with its full supply of empty bobbins f, these latter are made
to push the former from their positions on said lifter-rail to fall into the
hopper (or a shoot may be used instead of the hopper e³) for their reception,
while the empty bobbins f will have been placed in position on the lifter rail
to receive the spindles b on these latter being raised by their mechanism to their
operating position, after which the rail e is withdrawn to its backward position,
while the flyers are also placed on their spindles by the rotation of the latter,
and, by the employment of any of the well known devices, the whole series of
threads will be twisted or wound for a few revolutions around said empty bobbins,
thus preparing the whole ready to recommence their actions, the full bobbins in
the hopper being at this time held against rotation in order that their ends
will be broken on the rotation of the spindles, by means of the weight of the
chain e¹ which extends the whole length of said hopper e³, the chain being sup-
ported at intervals by the arms which are hinged at 6 in order that said chain
may be moved away whenever necessary.
To place a fresh set of empty bobbins f in the clips e¹, the rail e is lowered to
a suitable position, and moved to the front of the machine by means of the
levers fo.

To attain the object of our invention in connection with those machines known
Cap spinning and twisting frames, we arrange the rail a which carries the
spindles 6 to be movable in a vertical direction, such movement being effected
by the rack and pinion c or by other suitable means.
We also mount a horizontal rail e (see Fig. 5) capable of being moved in some-
what vertical and lateral directions in the same manner and by means which are
practically identical with those herein before described with reference to the rail e
employed in connection with “flyer" spinning frames and as illustrated by
Figs. 1 and 2, or its vertical movements may be attained by means of the levers n
and operated by the hand lever n² (see Fig. 3). Mounted on the rail e are a
number of upwardly extending arms e² to which are attached the clips e¹ for sup-
porting the series of empty bobbins f.
We also mount and operate in a manner similar to that hereinbefore described,
a rail h, to which are attached a number of projecting arms or supporting pieces h³
which engage, when in the position illustrated by the several drawings, with
notches m¹ formed in the caps m.
When it is desired to replace the full bobbins f¹ with the empty ones f, the
former are lowered by means of the spindle rail a and lifter rail (both of which
move together by means hereinafter described) into the desired position where
they are held by suitably shaped supports or holders o extending from the parts e
of the arms e, the spindles & being further lowered so as to pass entirely through
and below said bobbins f.
The horizontal rail e with its supply of empty bobbins f is then moved so that

page_text: the said empty bobbins f will be carried into position over the spindles b, on
which said spindles are raised to such a position that they prevent the displacement
of the empty bobbins f on the withdrawal of the rail e which takes place at this
time, such withdrawal of the rail e and and supports o causing the full bobbins
to be projected into the hopper e³ where they are held against rotation by the
means herein before described.
If desired instead of making use of the holders o, we may arrange separate
clips to-lay-hold-of the bobbins f¹, in which case they (said bobbins) will be
projected into the hopper e³ on the advancing movement of the empty bobbins f.
At this period it is necessary that the yarns should be wound a few times around
the empty bobbins f for purposes well known, and this is accomplished by means
of the hooked parts p (mounted on the rod g) which are at this time advanced
into the position indicated by the several drawings by means of the rail p¹ movable
in the slot 2, through the hand lever p³ fulcrumed at 4, and link p. The rod g
is loosely carried by the pins q which are eccentrically mounted on the plates q¹
the studs q projecting therefrom being free to revolve within the bar p', but
have cranks 3 operated by the rod q2 mounted at their upper ends, hence, on the
threads being placed within the hooked parts p, and a rotary motion given to
the cranks by means of a suitable handle part attached to the bar q2 a rotary
motion around the spindles b is given to the hooked parts p through the bar q
thus causing the threads to be wrapped for a few turns around the empty bobbins
as desired.
The spindle rail a is now raised so that the spindles 6 pass above said empty
bobbins and within the caps m, on which the projecting parts h are withdrawn
from the positions indicated by the drawings wherein they support the caps m, the
latter now resting upon their spindles in the usual manner, after which the parts
are ready for the machine to recommence its operations.
In order to cause the lifter rail to always move relatively with the spindle
rail a, I attach a chain r to the latter, this chain passing around the pulleys 1, 2,
and, to be connected to the foot s of the lifter mechanism. the rod s extending
from said foot s to the lifter plate 4, so that any vertical movement: given to
the spindle rail a will be transmitted through said chain r, foot s and rod s¹ to
the lifter plate k, while during the time that the yarn is being wound on to the
bobbins and the spindle rail a is stationary, the lifter rail is moved as desired
by means of the pulleys 1, 2, 3, and chain r, the pulley 2, being moved in the
direction of the arrow t by the bar t¹ (said pulley being fixed to this bar) which
is operated by means of the spur wheel u fixed on the shaft u, gearing with a
rack on said bar t¹, the shaft u¹ receiving its rotary motion from the horizontal
movement of the well known screwed shaft w through the chain w¹ and pulleys w
and w³.
It will be readily understood that without departing from the nature of our
said invention, we may make slight modifications in certain of the parts of our
mechanism, such as the substitution of slightly different methods of transmitting
motion to the various movable rails.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:--
1. In doffing mechanism. for the bobbins of spinning and twisting machinery,
the use or employment of a movable step or spindle rail as and for the purposes
substantially as herein specified.
