Improvements in or applicable to Machines for Winding and
Doubling (Doubling and Twisting) Yarns or Threads.
We, HENRY BIRKBY ARUNDEL of Sovereign Works, Stockport, in the
County of Chester, Machine Maker, and JOSEPH HIGGINSON Junior, of the
same place, Machinist, do hereby declare the nature of the said invention, to be as
follows:-
Firstly. The object of our invention is mechanism to be applied to winding and
doubling frames (doubling and twisting) for distributing the yarn or thread upon
the bobbius or spools so that it may be wound in parallel layers at the lower or
head end of the spool or bobbin and taper at the top or headless end of the spool
or bobbin in order that it may readily unwind from the top or headless end of the
spool or bobbin.
The object of our invention may be carried into effect by a variety of
combinations and arrangements of mechanism, but the essential feature of our
invention consists in adding arrangements or combinations of mechanism to the
ordinary mechanism for distributing the yarn or thread upon the spool or bobbin
so as to modify its action, that is, to superimpose or give an additional movement
to the ordinary lifter rail which can add to the extent of the ordinary traverse
motion, a motion that will produce a taper form in the yarn or thread at the top or
headless end of the spool or bobbin, the yarn or thread being so crossed at such
taper end as to draw off endways when being unwound from the spool or bobbin
without ravelling or stripping off.
One combination for carrying out our invention consists in arranging mechanism,
say a cam on an arm from the lever operated by the heart wheel, which cam is
arranged to come against the chain extending between an arm of the lever
actuated by the heart wheel and the shaft which transmits movement to the ring
rail or thread distributor, the said cam having intermittent rotary motion imparted
to it by a stationary pawl jointed on the framing.
This cam causes the chain to bend or be deflected and thus add to the extent of
the ordinary lift, the shape of the cam producing a variable amount of bend or
deflection.
In place of a cam, other equivalent mechanism may be substituted.
By another modification of our invention, the end of the chain transmitting
movement from the heart wheel is not connected directly to the lever acted upon
by the heart wheel but to say the end of a two armed lever having its fulcrum
carried upon the lever acted upon by the heart wheel. One arm of the two armed
lever is against a stop during the ordinary lifting movement, but near the
termination of this movement the inner arm of the two armed lever comes against
a cam carried on a stud in the framing and this gives the additional movement to
the traverse at the upper, top or headless end of the spool or bobbin.
The said cam may be of any desired shape, and may be rotated intermittently by
a pawl connected with the lever acted upon by the heart wheel.
In place of the cam, other equivalent mechanism such as a screw or incline may
be substituted.
The two armed lever may be arranged to be acted upon directly by the
Baid cam.
By another modification the movement from the heart wheel is transmitted
through 66
sun and planet or "differential gearing" the axis carrying the
"

page_text: intermediate bevel wheel of the differential gearing being held by a stop during
the ordinary movement, but is acted upon to give the additional movement to form
the taper winding by a cam on a stud or other equivalent carried on the lever
acted upon by the heart wheel which cam comes against the axis carrying the said
intermediate bevel wheel when near the highest position moving it away from its
stop to give the additional movement to form the taper winding, this cam or
equivalent being rotated or acted upon intermittently by a pawl jointed on the
framing; screws, inclines or other equivalent mechanism may be substituted for
the cam.
The second part of our invention has the same object as the first part of our
invention, but this second part of our invention is only applicable to winding
frames in which the bobbins or spools are placed upon vertical spindles, and the
threads are distributed by a traverse or guide bar passing the lengthway of the
frame in front of the spindles, this traverse or thread distributing bar moving up
and down vertically.
To the ordinary guide or distributing bar or rail a supplementary guide rail is
aitached.
It may be mounted upon a series of levers having their fulcrums on the ordinary
guide rail, and these carrying levers may be connected together by a rod passing
lengthway of the ordinary guide rail so that the supplementary rail can move
vertically parallel to the ordinary guide rail. Or this additional rail may be
mounted and arranged in any other convenient manner. This auxiliary rail rests
against a support on the main or ordinary lifter rail during the lower part of the
lift, but during the upper part of the lift a lever from or actuating the auxiliary
rail comes against a stop, that gives it a lifting movement in addition to that
which it receives from the movement of the ordinary rail. This stop may be a
chain or other connection. The period at which this stop comes into action may
be changed in a variety of ways.
In one modification of our invention, the lever operating upon the auxiliary rail,
may be acted upon at different points by means of a cam or other equivalent
mechanism either continuously or intermittently operated by some moving part
from the machine.
Instead of the cam being on the framing it may be on the lever actuating the
auxiliary rail, and may come against a stationary stop upon the framing.
We also arrange the mechanism by means of a cam or equivalent mechanism so
that the additional traverse arranged as hereinbefore described, will rise to a
higher point than the previous one until the highest point is reached, so as to
effectually cover the layer of yarn or thread previously wound and thus prevent
ridging and tendency to ravel off in unwinding from the end. The cam is or may
be actuated continuously or intermittently by a pawl and a ratchet wheel attached
to the cam.
By another modification of our invention, we use a stop fixed to the framing to
actuate the lever, connected with the auxiliary rail, through a chain or other
suitable connection, the length of which chain can be varied by a cam or other
equivalent mechanism actuated from the moving parts of the machine in any
convenient manner.
By another modification of our invention, we mount the fulcrum of the lever
connected with the auxiliary rail on a crank pin or excentric which can be rotated
in any desired manner from any convenient part of the mechanism and thus give
additional and variable traverse for winding the yarn or thread taper as herein-
before explained.
Variation in the auxiliary traverse may also be made by transmitting the
movement to it through increasing or decreasing leverage, changed automatically
by a cam or equivalent means.

page_text: Improvements in or applicable to Machines for Winding and
Doubling (Doubling and Twisting) Yarns or Threads.
We, HENRY BIRKBY ARUNDEL of Sovereign Works, Stockport, in the
County of Chester, Machine Maker, and JOSEPH HIGGINSON Junior of the same
place, Machinist, 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 :-
Firstly. The object of our invention is mechanism to be applied to winding and
doubling frames (doubling and twisting) for distributing the yarn or thread upon
the bobbins or spools so that it may be wound in parallel layers at the lower or
head end of the spool or bobbin and taper at the top or headless end of the spool
or bobbin in order that it may readily unwind from the top or headless end of the
spool or bobbin.
The object of our invention may be carried into effect by a variety of
combinations and arrangements of mechanism but the essential feature of our
invention consists in adding arrangements or combinations of mechanism to the
ordinary mechanism for distributing the yarn or thread upon the spool or bobbin
so as to modify its action, that is, to superimpose or give an additional movement
to the ordinary lifter rail which can add to the extent of the ordinary traverse
motion, a motion that will produce a tapar form in the yarn or thread at the top or
headless end of the spool or bobbin, the yarn or thread being so crossed at such
taper end as to draw off endways when being unwound from the spool or bobbin
without ravelling or stripping off.
One combination for carrying out our invention consists in arranging mechanism,
say a cam on an arm from the lever operated by the heart wheel, which cam is
arranged to come against the chain extending between an arm of the lever
actuated by the heart wheel and the shaft which transmits movement to the ring
rail or thread distributor, the said cam having intermittent rotary motion imparted
to it by a stationary pawl jointed on the framing.
This cam causes the chain to bend or be deflected and thus add to the extent of
the ordinary lift, the shape of the cam producing a variable amount of bend or
deflection.
In place of a cam, other equivalent mechanism may be substituted.
By another modification of our invention the end of the chain transmitting
movement from the heart wheel is not connected directly to the lever acted upon
by the heart wheel but to, say the end of a two armed lever having its fulcrum
carried upon the lever acted upon by the heart wheel. One arm of the two armed
lever is against a stop during the ordinary lifting movement, but near the
termination of this movement the inner arm of the two armed lever comes against
a cam carried on a stud in the framing and this gives the additional movement to
the traverse at the upper, top or headless end of the spool or bobbin.
The said cam may be of any desired shape, and may be rotated intermittently
by a pawl connected with the lever acted upon by the heart wheel.
In place of the cam, other equivalent mechanism such as a screw or incline may
be substituted.
The two armed lever may be arranged to be acted upon directly by the
said cam.
By another modification the movement from the heart wheel is transmitted
66
"
through sun and planet or "differential gearing" the axis carrying the
intermediate bevel wheel of the differential gearing, being held by a stop during
the ordinary movement, but is acted upon to give the additional movement to form

page_text: the taper winding by a cam on a stud or other equivalent carried on the lever
acted upon by the heart wheel, which cam comes against the axis carrying the
said intermediate bevel wheel when near the highest position moving it away from
its stop to give the additional movement to form the taper winding, this cam or
equivalent being rotated or acted upon intermittently by a pawl jointed on the
framing; screws, inclines or other equivalent mechanism may be substituted for
the cam.
The second part of our invention, has the same object as the first part of our
invention, but this second part of our invention is only applicable to winding
frames in which the bobbins or spools are placed upon vertical spindles, and the
threads are distributed by a traverse or guide bar passing the lengthway of the
frame in front of the spindles, this traverse or thread distributing bar moving up
and down vertically.
To the ordinary guide or distributing bar or rail a supplementary guide rail is
attached.
It may be mounted upon a series of levers having their fulcrums on the ordinary
guide rail, and these carrying levers may be connected together by a rod passing
lengthway of the ordinary guide rail so that the supplementary rail can move
vertically parallel to the ordinary guide rail. Or this additional rail may be
mounted and arranged in any other convenient manner. This auxiliary rail rests
against a support on the main or ordinary lifter rail during the lower part of the
lift, but during the upper part of the lift a lever from or actuating the auxiliary
rail comes against a stop that gives it a lifting movement in addition to that which
it receives from the movement of the ordinary rail. This stop may be a chain or
other connection. The period at which this stop comes into action may be
changed in a variety of ways.
In one modification of our invention the lever operating upon the auxiliary rail,
may be acted upon at different points by means of a can or other equivalent
mechanism either continuously or intermittently, operated by some moving part
from the machine.
Instead of the cam being on the framing it may be on the lever actuating the
auxiliary rail, and may come against a stationary stop upon the framing.
We also arrange the mechanism by means of a cam or equivalent mechanism so
that the additional traverse arranged as herein before described will rise to a
higher point than the previous one until the highest point is reached, so as to
effectually cover the layer of yarn or thread previously wound, and thus prevent
ridging and tendency to ravel off in unwinding from the end. The cam is or may
be actuated continuously or intermittently by a pawl and a ratchet wheel attached
to the cam.
By another modification of our invention, we use a stop fixed to the framing to
actuate the lever, connected with the auxiliary rail, through a chain or other
suitable contection, the length of which chain can be varied by a cam or other
equivalent mechanism actuated from the moving parts of the machine in any
convenient manner.
By another modification of our invention, we mount the fulcrum of the lever
connected with the auxiliary rail on a crank pin or excentric which can be rotated
in any desired manner from any convenient part of the mechanism and thus give
additional and variable traverse for winding the yarn or thread taper as herein-
before explained.
Variation in the auxiliary traverse may also be made by transmitting the
movement to it through increasing or decreasing leverage, changed automatically
by a cam or equivalent means.
The illustrations to be hereinafter described only show so much of the
mechanism of the machines to which our invention are applicable as will be
required to clearly explain the same.
Fig. 1, is an end elevation partly in section illustrating one modification under
the first head of our invention.

page_text: We will first refer by letters of reference to the ordinary well known parts or a.
ring frame.
a,
is the spindle rail; b, represents an ordinary spool or bobbin with a large-
lower and a small upper head on which the yarn or thread is wound in the cone
form at the upper or drawing off end when the yarn or thread is wound from the
bobbin or spool.
c, is the ring rail for distributing the yarn or thread as it is twisted, upon the
bobbins upon the spindles.
This ring rail e, is carried in the ordinary manner upon the upper ends of rods c',.
sliding vertically in bearings in the spindle rail a.
These rods c', are commonly termed "pokers" and a bracket is secured on the
lower end of each poker to which one end of a jointed chain c², is attached by
adjusting screws-the upper end of the jointed chain is securel to a cylindrical
block c³, attached to a shaft c, in suitable bearings passing in the lengthway of the
machine.
At one end of the shaft c', there is a cylindrical block or pulley c³, to which one
end of a jointed chain c, is attached, the other end of which is secured by adjusting
screws to a side projection at the end of one arm of a bell crank lever c³, having its.
fulcrum on a stud c, in the framing.
The other shorter arm of the bell crank lever c', has a bracket c³, secured to it
carrying a bowl d, that works against the face of a heart wheel d, on a suitable
shaft d', in bearings on the framing.
The weight of the ring rail c, and pokers c¹, is sufficient to keep the bowl d²,.
against the heart wheel d.
All the parts so far described by reference letters are ordinary and well known
parts of ring frames.
e,
To the long arm of the bell crank lever c', according to our invention, we secure-
a bracket
in which a stud el, is secured upon which a ratchet wheel e, is mounte
and to the ratchet wheel or its boss, an excentric e³, is secured, the edge of which
is arranged to come opposite the jointed chain cº, between the bell crank lever and
the circular block c, on the copping shaft c*.
In the bracket e, there is a stud e', for a pawl e, having a weighting tail to bring-
the pawl against the teeth of the ratchet e².
On a stud e, in the framing, there is a pawl arm e', the face of which rests or
passes over the teeth of the ratchet e², and this pawl arm e', has a tooth that will
come in contact with the teeth of the ratchet e², when or about the time the long
arm of the bell crank lever c', is at its highest position; and this will cause-
the ratchet wheel e³, to rotate one tooth or more according to the position in which
the ratchet pawl e', is adjusted.
It will now be seen that without the excentric e³, the ring rail c, would be actuated
in the ordinary manner (with an unvarying up and down length of traverse) but.
with the excentric e³, the jointed chain c, will be deflected from a straight line and
this will add a greater. lift or traverse to the ring rail c, varying in amount
according to the position of the excentric e³, as produced by the rotation of the
ratchet wheel e. Thus the ring rail e, always descends to the bottom, but does not.
always ascend to the top of the bobbin, the upward traverse being varied in length.
by the action of the excentric e³, so that say only about every seventh layer (more-
or less as arranged) would extend to the full lift or length of the traverse,
the other six layers in every seven being more or less short of the full length of the
traverse.
Fig. 2, is an end elevation illustrating a modification of the arrangement shown
by Fig. 1.
c, is the copping shaft having the circular disc or pulley e, secured to it to the-
edge of which one end of a jointed chain c, is secured.
d, is the heart wheel; c', the bell crank lever, to the long arm of which a two-
armed leverf, is jointed on a stud f', secured in the side of the long arm of the bell
crank lever.

page_text: This two armed lever f, has a slotted hole in each end and the lower end of a rod,
a continuation of the jointed chain c, passes through the slot at the outer end of the
two armed lever f, and there is a "knife edge", on the rod which is adjustable
against the underside of the lever f, by a screw nut on the end of the rod.
There is a similar arrangement of rod f³, connected with the other end of the two
armed lever f, and the upper end of this rod f³, has a "knife edge" arrangement
upon it resting against a notch in a lever, having its fulcrum on a stud f, in the
framing. The free end of the lever, is bent downwards and is pointed and rests
against the edge of a heart wheel g, attached to a ratchet wheel g³, on a stud g², in
the framing.
On the same stud g², a lever 93, is jointed, and this lever g³, has a ratchet
pawl g, jointed to it that comes against the teeth of the ratchet wheel g¹, by its own
weight.
The edge of the lever g³, rests upon the end of an arm go, secured upon the
copping shaft, so that as such shaft oscillates the lever g³, is vibrated up and down
and this causes the ratchet wheel g', to be rotated.
There is a retaining pawl 98, on a stud 97, in the framing, acting upon the teeth
of the ratchet wheel g'.
When the long arm of the bell crank lever c', lifts, the ring rail c, (see Fig. 1)
descends and during that time the outer end of the two armed lever f, comes
against the end of an adjusting screw 98, screwing through a projection from the
long arm of the bell crank lever c', so that in such position of the two armed levert,
the ring rail c, is actuated as if directly from the heart wheel d, in the ordinary
manner but when the long arm of the bell crank lever c', descends towards its
lowest position, the rod f³, connected with the heart wheel g, gives extra vertical
movement to the ring rail c, in its upper position and this will vary according
to the changing position of the heart wheel g, connected with the ratchet
wheel g¹.
Fig. 3, is an end view and Fig. 4, a plan view of part of the mechanism shown
in Fig. 3, illustrating another modification of our invention where differential
gearing or bevel wheels are used.
d, is the ordinary heart wheel; c', the bell crank lever, the long arm of which is
adjustably attached to the lower end of a rod connected with the jointed chain cⓇ,
attached to the boss of a bevel wheel h, (see Figs. 3 and 4) loose on the copping
shaft c*.
This bevel wheel, gears with one 2, that is free to rotate on an arm h¹,
jointed and free on the copping shaft c, which bevel , also gears with a bevel h³,
secured upon the copping shaft c*.
It will be seen that the movements of the bell crank lever , operate to oscillate
the copping shaft c, through the bevel wheels and as long as the axis or
arm, of the middle bevel 2, is stationary the movements imparted to the copping
shaft are uniform.
There is an adjustable stop formed by the end of a set screw h³, screwing through
a bracket, secured to the framing, the end of which set screw comes against the
collar on the arm ', for the middle bevel 2, and keeps the arm ¹, in that position
unless depressed.
To depress the .arm ', and make the required variations there is an excentric e³,
on or attached to a ratchet wheel e², on a stud e¹, secured in a projection from the
short arm of the bell crank lever c'. The edge of the excentric e³, comes against
the said arm h', according to its position which is varied by a pawl e', jointed
on a stud in a lever e, which is jointed on the stud e', for the ratchet wheel e², and
excentric e³.
The upper part of the lever e³, comes against a stop e, in the framing so that as
the bell crank lever c³, moves to and fro oscillations are produced in the lever e³, and
the ratchet wheel 2, is rotated.
The ratchet wheel is arranged with sufficient friction so as not to rotate too
easily. There may be a retaining pawl (not shown) to act upon the ratchet

page_text: wheel e³, this pawl being jointed on a stud secured in the projection from the short
arm of the bell crank lever c².
Fig. 5, is an end elevation partly in section and Fig. 6, a front view illustrating a
modification according to the second part of our invention.
b, represents one of the bobbins or spools supposed to be upon a vertical spindle,
on such bobbins the yarn or thread is wound.
j, is the ordinary up and down traversing bar for distributing the yarn or thread
on the bobbins as it is wound thereon.
The threads come in the line r, over a rod a¹, through a vertical slit in a guide j',
and over another rod 2, and then passes to the bobbins. This is an ordinary
arrangement.
According to this part of our invention we add another rod k, for the threads to
pass over, and this additional rod k, passes in the lengthway of the ordinary thread
distributing bar j, and is carried thereon in the ends of bell crank levers k¹.
placed at intervals, the fulcrums 2, of which are secured in the ordinary distributing
bar j, shown in Fig. 5.
This arrangement is illustrated by Fig. 6, where the additional rod k, is shown,
and one bell crank lever k¹.
The vertical arms of all the bell crank levers k¹, are connected together by a wire
or rod k³, passing from end to end of the ordinary distributing bar j, there being an
adjustable collar 4, on the rod or wire k³, for each bell crank lever k¹, and thus by
giving end movement to the rod or wire k³, the horizontal arms of all bell crank
levers k, are simultaneously raised and lowered, the weight of the additional bar k,
keeping the actuating rod or wire ³, in tension.
To the rod or wire k³, a bracket, is adjustably secured to which one end of a
rod is attached by an adjusting screw, this rod is a continuation of a chain or
baud ko, secured to it that passes over a pulley k', on a stud k³, secured in the
ordinary distributing rail.
The lower end of this chain, cord or wire k, is attached to the end of a lever k³,
having its fulcrum on a stud ka, in the framing.
This lever, has an upward projection, that comes against a snail cam ko,
attached to a ratchet kd, on a stud ko, in the framing. This ratchet wheel ka, has
a retaining pawl, jointed on a stud in the framing which pawl acts upon the
ratchet wheel kª.
There is a ratchet pawl k, jointed to the side of the lever k, which has a hook
formed at its upper end which will catch upon the teeth of the ratchet wheel kª, as
the lever k, moves up and down.
This vertical pawl arm ks, has a projection from it for an adjustable set screw kb,
the end of which comes against the edge of the arm k, and by this set screw kb,
the hook end of the pawl k³, can be adjusted to the teeth of the ratchet
wheel kd.
When at work the rise and fall of the ordinary distributing bar j, (Fig. 5) will
cause the end of the arm of the lever k³, to move up and down at the same time, and
when the lever k, ascends, its projection Ab, will come against the edge of the
cam ke, and as this takes place before the ordinary distributing bar j, has attained
its highest position the bell crank levers k¹, and thus the additional rod k, is lifted
higher than the distributing surfaces or rods a², of the ordinary distributing bar j,
and the threads are lifted to wind upon a higher position upon the bobbins
accordingly.
If the cam k, did not rotate, the action would be the same for each lift of the
ordinary distributing bar j, but as the cam ko, is rotated step by step, it becomes a
variable stop to the projection kb, upon the lever k³, and thus causes a varying
amount of lift to the additional distributing bar or rod k.
Fig. 7, is an end elevation which illustrates another modification of our
invention.
k, is the pulley on the ordinary distributing bar j, see Fig. 5, round which the
chain or cord, passes, connected with the wire or rod k³, Fig. 6, at one end and

page_text: with the end of a lever k, having its fulcrum at ka, on the framing. The snail
cam k for producing the variable stop can rotate on a stud, fixed in the
side of the lever k³, this cam ke, being attached to and rotating with a ratchet
wheel kd.
There is also a retaining pawl k³, to act upon the ratchet wheel kd, the stud for
which is secured in the side of the lever kº. There is a bracket k³, secured
to the framing of the machine above the snail cami ke, and this bracket has a
projection for an adjustable set screw, the end of which comes against the edge of
the cam kc.
To the bracket k', the end of a hook pawl kk, is also jointed which hook pawl acts
upon the teeth of the ratchet kd, and causes it to take one or more teeth as arranged
at each up and down movement of the lever k³.
It will be seen that as the pulley k', is carried upon and moves up and down with
the ordinary distributing bar j, the lever, will also move up and down at the same
time, and as the edge of the snail cam ke, does not come against the end of the set
screw at the lower part of the lift the additional thread distributing bar k, does not
then operate, but when in its ascent the cam ke, comes against the end of the set
screw k³, movement is then imparted to the additional thread bar k, and this
movement will vary according to the rotary position of the snail cam ke.
Fig. 8, is an elevation illustrating another modification of our invention.
k', is the pulley on the ordinary distributing rail or bar i, shown in Fig. 5; k, is
the chain or cord passing from the rod or wire k³, shown in Fig. 6, connecting the
bell crank levers k¹, for actuating the additional rod or bar k-which chain or
cord ko, is attached to a plunger l, working up and down in a tubular part 1, which
is guided at its lower end in a hole in a frame 1, secured to the framing of the
machine.
The lower end of the tubular part P, has a head 13, upon it, or it may be
an adjusting screw.
Across the plunger 1, there is a hole or bearing for a short shaft l, passing
through slots in the sides of the tubular part 1.
Upon one end of the short shaft 1, outside the tubular part 1, a ratchet wheel 1³,
is secured and upon the other end a heart cam 16, is secured, the edge of which cam
cones against a bowl on a stud 1, in the side of the tubular part
The plunger, the short shaft and the ratchet and heart cam, is thus drawn up
until the heart cam 1º, comes against the bowl on the stud 17.
Or in other words, the tubular part 1, and the bowl on the stud 1', descends until
the bowl rests upon the edge of the heart cam 10, consequently the height of the
tubular part 1, or the distance of the head 13, at its lower end below the bottom of
the frame 12, will depend upon the position of the heart cam 16, and will vary as the
heart cam rotates.
The plunger and tubular rod and ratchet wheel rise and fall with the ordinary
distributing rail j, and there is a hook pawl 18, jointed on the frame 12, that acts to
rotate the ratchet wheel 15, one or more teeth at each up and down movement, and
there is also a retaining pawl 1, jointed on the plunger l.
Thus arranged it will be seen that the head 13, of the tubular bar 1, will come
against the underside of the frame 2, sooner or later according to the rotary
position of the heart cam 16, but if the heart cam did not rotate, the movement would
be constantly the same and would not be varied.
Fig. 84, is an elevation illustrating another modification somewhat similar to
Fig. 8.
k, the pulley for the cord or chain k, which is attached to the upper end of a
rod n, that can slide through a hole in the boss of a cam n³, arranged to rotate in a
frame secured to the framing of the machine.
This cam n¹, has a worm wheel n³, formed upon its edge that gears with a worm n³,
on a shaft n', in bearings on the frame 12, and this shaft nt, has a pulley no, secured
at its end for an endless band by which it can be rotated from a pulley on the shaft,
say for the heart wheel actuating the ordinary distributing bar ;, or from any other

page_text: convenient shaft of the machine. This shaft n, may if desired be rotated
intermittently by a pawl and ratchet wheel or otherwise.
The rotary cam n¹, is the counter part of another cam ne, secured on the lower
end of the rod n, and there are projections n', from this cam 2°, to form guides to
slide up and down on the vertical sides of the frame 12, thus keeping the lower cam n®,.
from rotating when moving up and down.
The rotary and fixed cams are counter parts just as if both were formed out of
the same cylinder and separated by an helical cut forming one thread of a screw,
such drum cams giving the same result as a snail cam. The cams n' and n³, may
be double, that is to say, there may be one rise and fall in each half revolution of
the cam so that the cams will always come together on opposite sides of the axis of.
the cams.
It will be seen that in working, the faces of the cams will meet but at different
distances apart varying with the position of the rotary cam.
Fig. 9, is a side elevation and Fig. 10, an end elevation illustrating another.
modification of this part of our invention.
m, is a bracket secured to the framing of the machine. It is tubular to form the
bearing for a shaft m', having a worm m³, secured upon it at one end which gears.
The boss m',.
with a worm wheel m³, on a stud m', in the framing of the machine.
of this worm wheel m³, is excentric to the stud m³, and the fulcrum end of a lever m³,
fits upon the excentric, the other end of the arm or lever m³, has the cord or
chain ko, attached to it herein before referred to in Figs. 6, 7 and 8.
From the bracket m, there is a downward projection me, against which the upper
edge of the lever m³, comes when the ordinary distributing bar j, or rail makes its.
ascent when near the upper part of its lift. This lever m³, will come against the
is
stop me, sooner or later according to the distance the fulcrum of the lever m³,
of
from the stop me, and this is varied by the rotation of the excentric fulcrum m³,
the lever m³.
A ratchet wheel m³, is secured upon that end of the shaft m', in the bracket m,
opposite to that end where the worm m³, is secured and a bell crank lever m³,
is arranged to oscillate upon the end of the shaft m', and the vertical arm of this
bell crank lever has a pawl m³, jointed to it to work upon the ratchet wheel m³.
The underside of the horizontal arm of the bell crank lever m³, rests upon
a projection mb, from the lever m³, consequently it partakes of the up and down
movement of that lever and thus rotates the ratchet wheel and the worm, worm,
wheel and excentric.
We wish it to be noted that the snail form of cam ke, Figs. 6 and 7 and its.
equivalent in Fig. 8A, act to cause each layer of yarn or thread wound upon the
small end of the bobbin to so cover the preceding layers of thread as to
prevent the threads from ravelling or stripping off when being unwound from the
bobbin.
Such shape and arrangement of cams or other equivalent mechanism producing
the like result may be used for both ring and winding frames of the class herein before.
referred to, but are more particularly applicable to winding frames.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we wish it to be.
understood that we do not limit ourselves to the details, but claim :-
1. In ring frames, the combination with the ordinary copping or ring rail
mechanism, of mechanism for giving additional or supplementary movements.
varying in extent to the ring or copping rail, substantially as and for the purpose
herein before described.
2. In ring frames the combinations and arrangements of mechanism substantially
as and for the purpose hereinbefore described and illustrated by Fig. 1, Fig. 2,.
and Fig. 3 of the drawings.
3. In winding frames, the combination with the ordinary yarn or thread
distributing mechanism, of mechanism for giving additional or supplementary
t

page_text: movements varying in extent to the thread distributing mechanism substantially
as and for the purpose hereinbefore described.
4. In winding frames where the yarn or thread is wound upon bobbins upon
vertical spindles the combinations of mechanism substantially as and for the
purpose hereinbefore described and illustrated by Figs. 5 and 6, Fig. 7, Fig. 8,
Fig. 84 and Figs. 9 and 10 of the drawings.
5. In ring and vertical winding frames having additional or supplementary
movements of varying extent combined with the ordinary yarn or thread
distributing mechanism, the use and combination with such mechanism of a snail
cam (similar to k°, Figs. 6 and 7, or its equivalent shown in Fig. 8^) or other
equivalent mechanism producing a like result, for operating the traverse of the
thread distributing mechanism so that succeeding layers of yaru or thread wound
upon the small ends of the bobbins will so bind the preceding layers of yarn or
thread thereon, so as to prevent them from ravelling or stripping off in unwinding
from the bobbin substantially as hereinbefore described and illustrated by the
drawings.
