page_text: Improvements in Machinery or Apparatus for Doubling or Winding
Yarn from Cops or Bobbins upon Spools.
I JOHN WILLMARTH FOSTER of Pawtucket in the State of Rhode Island one of the
United States of America, Machinist do hereby declare the nature of this invention
to be as follows:-
This invention has for its object the production of a novel machine for doubling or
winding yarn from cops or bobbins upon spools.
Prior to my invention in all machines known to me for rotating a series of yarn-
spools through the intervention of a series of short cylinders, the said spools and
cylinders have been arranged with their axes parallel to the main driving shaft
extended through the machine longitudinally, and the cylinders have been connected
to a shaft which is driven positively, but this class of machine is objectionable because
the placing of the cylinders at the opposite sides of the frame in a line parallel to the
long sides of the frame takes up too much valuable floor space.
In the class of machine referred to it is necessary to either provide the heads of the
spools with tips or outward projections to form bearings; or to mount the spools on
independent skewers or rods extended through them to constitute journals.
;
The tips, when employed, are of metal and have to be oiled and the skewers, if
used, are liable to drop upon the floor, and being disconnected from the spool much
time is lost in putting them into and taking them from the spools.
So also in the class of machine referred to, the spools are weighted but in such
manner however that the weights have to be lifted separately by the operator when the
spools are to be removed.
In the class of machine referred to the length of the spool must always be the same,
and when a thread breaks, the particular spool to which the said thread was running
is lifted from the driving cylinder by a wedge or other contrivance, which acting
between the cylinder and the mass of thread on the spool, is liable to injure the thread
or yarn, and for this reason, together with the great space usually occupied by the
machine this class of machine has been generally condemned for winding yarn.

page_text: Being desirous of improving this class of machine, 1 havo devised a new doubling
and spooling machino wherein the axes of the cylinders for driving the spools, are
arranged transversely with relation to the length of the frame work, the cylinders at
opposite sides of the machine being parallel to or in line cach with the other, and as a
result thereof I am enabled to in the same length of frame employ nearly twice
as many spools.
In my improved machine I have interposed between the cylinders and spools a
series of independent drums which rest on the cylinders and constitute the drivers for
the spools and preferably these drums are covered with a fibrous or other soft jacket
against which rests the yarn being wound upon the barrel of each spool, these drums
having cooperating with them stop-motion devices, whereby on the breaking of a
thread the contact between the cylinder and the drum driving the spool is broken, and
the rotation of the drum and spool above it is stopped.
The spool employed by me is and may be of usual construction, and as herein shown
the spool has at each end a hole in line with the centre of the barrel, the said holes
receiving bosses extended from metallic cheeks having journals which enter slots in
the spool-stands, but instead the bosses may be on the heads and enter holes in the
checks.
The cheeks, one at each end of the spool, have projections which constitute journals
or bearing means for the spool, and the spool held between the inner sides of the said
cheeks may be readily lifted by a slight pull on the part of the operator when it is
desired to remove the spool, the said cheeks also serving as weights for and revolving
with the spools, and at the same time rising in the slots of the spool stands while the
spools are being filled with yarn, but when the spools are full the journals of the cheeks
pass automatically from their usual guiding slots into pockets communicating there-
with, the said pockets having overhanging edges or flanges and the said journals
having entered the said pockets, the rotation of the spool ceases, and the spool having
ceased to rotate, the yarn passing to it becomes slack permitting the drop-wires to fall
and operate the stop-motion for the drum driving that spool.
The portions of the spool-stands guiding the bearing means or journals of the checks,
are so constructed that one may be readily moved away from the other, taking with it
the cheek, thereby permitting the ready insertion or removal of a spool, the movable
portion of the spool-stand referred to being preferably hinged and also acted upon by
à suitable spring which acts to keep it in one position.
The feet of the spool-stands are bolted or fixed to a stand-rail extended from one to
the other end of the frame, the said stand-rail in turn being adjustably attached to a
permanent rail, the latter having preferably at each edge a suitable flange or upright
against which one or the other edge of the stand-rail may be brought, thus enabling
the spool-stands to occupy a position more or less apart to adapt them to
receive between them drums and spools of different length, this change being readily
effected.
In my improved machine the wave-motion is arranged above the spools in such
position that the operator may plainly see the yarn and reach it readily to correct any
faults.
The wave-motion consists essentially of a carriage sliding in ways transversely of
the frame, the said carriage having a series of guide-rods and eyes parallel to the axes
of the spools.
The wave-motion carriago is actuated by a sector-lever deriving its motion from a
toothed carriage actuated by a heart-cam, the point of the heart, or the part thereof
of greatest diameter and producing the greatest movement, being so arranged with
relation to the sector and carriage moved by it, that the quick motion of the heart
comes into operation as the motion of the wave-motion carriage is about to be roversed,
this being done to avoid any dead point in the movement of the said carriage, the more
uniform the movement of the said carriage, the more uniform the winding of the yarn.
My invention therefore relates to a series of horizontally placed driving cylinders
having their axes of rotation substantially at right angles to the frame-work; means
to rotate them; the series of drums resting thereon; and spool stands to guide the

page_text: journals or bearing means for the spools; the said spools having their axes of rotation

rotation substantially at right angles to the frame; means to rotate them; the series
of drums resting thereon and adapted to rotate a series of spools by frictional contact ;

Also, in a driving cylinder; means to rotate it; a drum resting thereon, and a
brake interposed between the said cylinder and drum, combined with means to actuato
the said brako to lift the drum from the cylinder and at the same time check the
rotation of the drum.

and rotated by the said cylinder, slotted spool stands, cheek pieces to hold frictionally
between them and clamp the spools and having journals free to enter and rotate and
slide vertically in the slots in the said spool stands.

the said cylinder and adapted to rotate a spool lying thereon, and spool stands pro-
vided with slots and overhanging flanges to form pockets combined with bearing means

when the spool has been filled.

between them the spool to be rotated, one of the said stands being made moveable in a
direction from and toward the other.

bearing means or journals for the spool to be rotated by the drum, combined with the
spool stands slotted diagonally and having an overhanging flange to form a pocket,
the said bearing means, as the spool fills, both rising and rotating in the said
slots until the bearing means meet the said flanges when the bearing means by the
increasing diameter of the yarn on the spool are forced laterally into the said
pockets.

and a brake, combined with a brake-actuating lever, a spring bolt of the stop-motion,
and means to actuate it.

Also, I arrange in a spooling machine, two series of driving cylinders arranged
transversely of the machine and having their axes substantially in line, two series
of drums parallel therewith and resting thereou, and two series of spool stands,
combined with bearing means, or journals, for the said spools, the axes of the drums

slotted spool-stands having flanges to leave pockets below them; two sets of drums
having their axes parallel to the axes of and resting on the said cylinders; and

its actuating cam-shaft being located above the said drums and spools thereon; a
series of brakes; brake-actuating lovers; and stop-motion devices, and with means
for moving the said stop-motion devices on the breaking of a yarn.
Suitable frame-work contains working parts and provides bearing and stand for
power shafting provided with fast and loose pullies said shaft having a pinion at its
inner end which engages another pinion on and rotates another or gear shaft having
attached to it at suitable intervals bevel gears, each of which engages a small bevel
pinion, secured to a transverse shaft to which is attached near each end a cylinder,
upon which by gravity rests a drum, or it may be the spool.
Each cylinder drives a drum, there being a spool resting on each drum, the axes of
the cylinders, drums, and spools, being parallel each to the other and all arranged
tranversely to the main shaft and to the length of the frame, for compactness, the
cylinders drum and spools at opposite sides the frame being preferably in line each
with the other.
The bearing stands for the cylinder shafts are secured to a longitudinal rail.

page_text: Each stand has a V-shaped bearing for one end of a shaft, and a slot for the
reception or an adjustable stud which constitutes the fulcrum for the brake-actuating
lever having at its upper end a toe, and at its rear side below its fulcrum another
shoulder, a shelf, and a stop, the said lever having hung upon it a weight which
normally turns the lever to bring the stop against a depending portion of the stand
except when the said lever is held in its full line position by the spring-bolt of the
stop-motion or by the starting lover.
The brake, one for each cylinder as an open centred concavo-convex plate, has
pivoted ears suitably secured to the under side of permanent rails the ears rising
past or above the inner edges of the rails.
Each brake is interposed between a cylinder and a drum resting by gravity on tho
said cylinder so long as the brake remains in its lowest position, but as soon as the
spring-bolt of the stop-motion mechanism is pushed out to release its inuer end
from the shoulder of the lever, the weight turns the said brake-actuating lever, causing
its toe to act upon the heel of and lift the brake and with it the drum above it from
contact with the cylinder which continues to run at speed.
Lifting the drum from the cylinder immediately disconnects the drum from its
source of motion, and at the same time the device which so lifts the drum acts as a
brake to instantly stop the rotation of the drum, overcoming all its tendency to move
by reason of momentum, and as the drum stops the spool stops.
The frame has three permanent rails whose flanges or upright portions as stops for
stand-rails adjustably secured extended through slots then entering the permanent rails.
These stand rails have bolted thereto feet of spool stands the lower portions of the
stands having vertical grooves for the reception of the journals at the opposite ends
of the drums.
By adjusting the stand rails on the permanent rails the bearing or spool-stands
and the stands are moveable to enable spools and drums of different lengths to bo
used.
The upper portions of the spool-stands have slots which receive the bearings for
the spools is the journals of weighted check-pieces between two of which the heads
or ends of the spools are clamped, the inner sides of the said cheeks, having a boss
to enter the usual recess at the centre of the spool-head.
To adapt spools with hollow metallic journals extended outwardly from their heads
to my improved machinery the boss is omitted and instead is provided a check with a
recess to receive the journal extending from the spool head.
The friction between the spool and cheek-pieces is sufficient to rotate both of
the cheek-pieces in unison with the spool as the journals turning in the slots and
rising therein as the spool is filled with yarn, and the spool filled these journals meet-
the overhanging edges or flanges of the said stands they extending substantially
across the slots and the journals thereafter pass laterally into a pocket which is a slot
in communication with another slot the said journal having entered the pockets
assuming the proper position the spool stopping as soon as the journals enter the
pockets.
As soon as the rotation of the full spool ceases, the yarn becomes slack and lowers
the drop-wire just as when a thread breaks, and the drop-wire effects the stopping
of the drum.
drum
The latter slot is inclined from a perpendicular and the pocket is nearly at right
angles to it and when the bearing means is in the lower end of the said slot (as
when the yarn is first applied to the spool) said journal occupies a position
at the right of the centre of rotation of the drum, in which position the
as
exerts its greatest leverage upon the spool, and the spool is
gradually filled, the bearing means therefor is gradually forced upwardly in
the slot the point of contact between the drum and the mass of yarn upon the spool
gradually approaching a line perpendicular to the axis of rotation of the journals, and
by the time that the spool is filled the bearing means for the spool arrive at the
junction of the slot and the pocket and are immediately forced as it were into the
pocket by the overhanging flange covering the slot and forming part of the pocket. .'

page_text: The spool-stands or some thereof are in parts connected or hinged which permits
the upper portion of the said stand to be turned outwardly with its attached check-
piece when it is desired to remove a spool from or to replace a spool between the two
check-pieces carried by the said stands, the pivotted or hinged portion being normally
held in upright position with its cheek-piece against one head of the spool by a strong
spiral spring connected to a stud near the foot of the stand and to a stud near the
pocket.
Yarn for each spool is taken from one or more bobbins or it may be spools and
passed over first a guide-rail thence through an eye at the upper end of a drop-wire
thence over a sheave on a bracket at the end of a cross arm of the frame through eyes
of the wave-motion rods and to the spools.
The lower end of the drop-wire, (having two parallel legs), is guided by a guide
composed of a metal plate attached to a block secured in suitable manner to the
underside of a plate resting on the top-board.
The spring-bolt of the stop-motion has suitable bearings near each end in which the
said bolt is free to slide, one of said bearings being in a stand, while the other bearing
is in a hole in the stand.
The bolt is normally pressed forward so that its inner end engages the shoulder
of the lever by a spiral spring surrounding the bolt between the stop-lug and the
stand.
The bolt has a second stop-lug and a lug to contain a pin on which is pivotied
and nearly balanced the tipping-lever of the stop-motion whose inner end is a trifle
heavier than its outer end so that it normally rests with its inner end upon the stop
and at such time the inner end of the said lever is out of range of the ratchet wheel
of the stop-motion, there being one such ratchet for each lever the series of ratchets
being connected to the stop-motion shaft.
The machine has at each side a stop motion shaft each having at its outer end a
sprocket-wheel connected by a chain with one of two sprocket wheels one on the
shaft just outside the frame the other on the hub of a pinion driven by the pinion
on the gear shaft, these stop motion shafts being rotated constantly, so that when-
ever a drop-wire for any cause descends upon the outer end of the lever it is tipped
to strike the stop and in so doing the rear or inner end of the lever is acted upon
by the rachet which pushes the bolt longitudinally outward releasing its end from
tho shoulder of the lever permitting the weight to move the lever and lift the
brake.
The lever liberated, the weight brings the shelf of each lever against the toe of
a starting lever pivotted on a bracket and connected by a link to a hand-piece
having a knob extended through a slot in the board the operator to start any drum
pulling the knob outward, causing the toe of the lever acting on the shelf to turn
the lever until the shoulder is again caught and held by the bolt such movement
lowering the brake and permitting the drum to rest on and be rotated by the
cylinder.
The stop motion shaft at that end of the machine opposite the fast and loose
pulley, has a pinion which engages and rotates a large toothed gear loose on a stud
the hub of the said gear having a sprocket-wheel which engages and moves a chain
extended over a sprocket-wheel fast on the heart-shaft of the wave motion the said
shaft having secured to it at suitable intervals one or more heart-cams each heart
in its rotation acting on the studs of a carriage provided with rack-teeth, and
adapted to slide in a guide-way fixed to an upright erected on the frame-work.
The one stud is fixed to the said carriage but the other stud is projected from
block held to the carriage loosely by a screw extended through a slot in the said
block, the outer end of the block being acted upon by a strong spiral spring located
between the block and an ear or lug on the carriage the spring serving to keep the
latter stud in contact with the heart and prevent any lost motion due to lack of
contact of the heart with the two studs.
Teeth of the carriage engage the toothed end of a sector-lever, the hub of which
surrounds a stud serving as a fulcrum for the said sector-lever.

page_text: The lower end of the sector-lever is slotted to receive within it an adjustable roller
or other stud entering an elongated slot in a stand connected by screws to the main
bar of the wave-motion carriage composed of the bar and suitable blocks or shoes
arranged at right angles thereto, and adapted to slido in guide-ways secured to
suitable uprights, the sector-lever in its movements causing the wave-motion carriage
to be reciprocated in a straight line transversely across the machine.
The wave-motion carriage has erected upon it, at suitable distances apart, logs
which receive a rod upon which at suitable intervals are clamped arms which at their
outer ends have adjustablo removeable wire eyes or guides one for each spool.
The slot in the sector-lever enables the roller or other stud to be adjusted therein
up or down according as a short or long spool is to be wound.
To avoid injurious effects in the winding from the wave-motion moving slower
while its motion was being changed from one to the other direction the point.
of the heart or the part of the heart of greatest diameter is placed so that it acts
upon the carriage to effect the vibration of the sector-lever and the movement of the
wave-motion carriage at the fastest speed is derivable just at the time that the direction
of movement of the wave-motion carriage is being reversed.
The sets of spools driven by the cylinders of each separate, shaft actuate spools.so
arranged with relation to each other that their axes of rotation substantially.
coincide one spool being however at one and the other at the opposite side of the
longitudinal centre of the machine.
"
This arrangement of the spools and consequently of the driving drums and cylinders,
the drums being on top of the cylinder, enables me to employ one wave-motion rod.
for two sets of spools arranged at opposite sides of the machine.
I do not desire to limit my invention to the exact form of stop motion devices
described on account of its extreme simplicity as instead of the said devices 1 might,
use any other suitable well-known form of stop motion devices; and, so also, while I
prefer the form of connecting mechanism herein mentioned between the heart-cam
and the wave-motion carriage, yet I may employ any other well known forms of
devices commonly employed for such purposes.
?
T
In my invention the stop-motion devices for all the spools, one at each side of the
frame are controlled by a single positively driven shaft which through a ratchet wheel
thereon acts upon any one of the spring bolts forming part of the stop-motion device
for each spool.
'
The spaces below the flanges and termed the pockets in which pockets pass the
bearing means for the spools, are in practice contracted at the outer, ends of the
pockets so as to prevent the said bearing means from passing out of the said pockets
except by considerable strain exerted by the operator so that the said bearing means
when the part is tipped over remain in the stand.
The stop motion devices, cylinders, drums, spools, and their supporting mechanism
are alike at both sides the frame.

Improvements in Machinery or Apparatus for Doubling or Winding
Yarn from Cops or Bobbins upon Spools.
JOHN WILLMARTH FOSTER of Pawtucket, in the State of Rhode Island one of the
United States of America, 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:—
This invention has for its object the production of a novel machine for doubling or
winding yarn from cops or bobbins
upon spools.
Prior to my invention in all machines known to me for rotating a series of yarn-
spools through the intervention of a series of short cylinders, the said spools and
cylinders have been arranged with their axes parallel to the main driving shaft
extended through the machine longitudinally, and the cylinders have been connected
to a shaft which is driven positively, but this class of machine is objectionable because
the placing of the cylinders at the opposite sides of the frame in a line parallel to the
long side of the frame takes up too much valuable floor space.
In the class of machine referred to it is necessary to either provide the heads of the
spools with tips or outward projections to form bearings; or to mount the spools on
independent skewers or rods extended through them to constitute journals.
The tips, when employed, are of metal and have to be oiled, and the skewers,
if used, are liable to drop upon the floor, and being disconnected from the spool much
time is lost in putting them into and taking them from the spools.
So also in the class of machine referred to, the spools are weighted but in such
manner however that the weights have to be lifted separately by the operator when the
spools are to be removed.
In the class of machine referred to the length of the spool must always be the same,
and when a thread breaks, the particular spool to which the said thread was running
is lifted from the driving cylinder by a wedge or other contrivance, which, acting
between the cylinder and the mass of thread on the spool, is liable to injure the
thread or yarn, and for this reason, together with the great space usually occupied
by the machine, this class of machine has been generally condemned for winding
yarn.
Being desirous of improving this class of machine, I have devised a new doubling
and spooling machine wherein the axes of the cylinders for driving the spools, are
arranged transversely with relation to the length of the frame-work, the cylinders at
opposite sides of the machine being parallel to or in line cach with the other, and as a
result thereof I am enabled to in the same length of frame employ nearly twice as
many spools.
.
In my improved machine I have interposed between the cylinders and spools a
series of independent drums which rest on the cylinders and constitute the drivers
for the spools, and preferably these drums are covered with a fibrous or other soft
jacket against which rests the yarn being wound upon the barrel of each spool, these
drums having cooperating with them stop-motion devices, whereby on the breaking of

page_text: a thread the contact between the cylinder and the drum driving the spool is broken,
and the rotation of the drum and spool above it is stopped.
6
The spool employed by me is and may be of usual construction, and as herein
shown the spool has at each end a hole in line with the centre of the barrel, the said
holes receiving bosses extended from metallic checks having journals which enter
slots in the spool-stands, but instead the bosses may be on the heads and enter holes
in the cheeks.
The cheeks, one at each end of the spool, have projections which constitute journals
or bearing means for the spool, and the spool held between the inner sides of the said
cheeks may be readily lifted by a slight pull on the part of the operator when it is
desired to remove the spool, the said checks also serving as weights for and revolving
with the spools, and at the same time rising in the slots of the spool stands while the
spools are being filled with yarn but when the spools are full the journals of the cheeks
pass automatically from their usual guiding slots into pockets communicating there-
with, the said pockets having overhanging edges or flanges and the said journals
having entered the said pockets, the rotation of the spool ceases, and the spool having
ceased to rotate, the yarn passing to it becomes slack permitting the drop-wires to fall
and operate the stop-motion for the drum driving that spool.
The portions of the spool-stands guiding the bearing means or journals of the cheeks,
are so constructed that one may be readily moved away from the other, taking with it
the cheek, thereby permitting the ready insertion or removal of a spool, the movable
portion of the spool-stand referred to being preferably hinged and also acted upon by
a suitable spring which acts to keep it in one position.
The feet of the spool-stands are bolted or fixed to a stand-rail extended from one to
the other end of the frame, the said stand-rail in turn being adjustably attached to a
permanent rail, the latter having preferably at each edge a suitable flange or upright
against which one or the other edge of the stand-rail may be brought, thus enabling
the spool stands to occupy a position more or less apart to adapt them to receivo
between them drums and spools of different length this change being readily effected.
In my improved machine the wave motion is arranged above the spools in such
position that the operator may plainly seo the yarn and reach it readily to correct any
faults.
The wave motion consists essentially of a carriago sliding in ways transversely of
the frame, the said carriage having a series of guide-rods and eyes parallel to the
axes of the spools.
The wave motion carriage is actuated by a sector-lover deriving its motion from a
toothed carriage actuated by a heart-cam.
In my first experiments wherein I employed a heart cam of usual shape to actuato
the carriage D and toothed sector to move the wave motion carriage I found that the
yarn piled up near each end of the spool leaving a hollow sector in the yarn between
the ends of the spool, and to overcome this difficulty I had to, and did, enlarge the
diameter of the heart cam at or near the double dotted lines therein, in Figure 1. such
enlargement enabling me to start the movement of the wave motion carriage quicker
as the sector passed its true vertical position in either direction and to wind yarn from
the centre of the spool to its ends and back to the centre between its ends.
My invention relates to a series of horizontally placed driving cylinders having their
axes of rotation substantially at right angles to the frame-work; means to rotate them;
the series of drums resting thereon; and spool stands to guide the journals or bearing
means for the spools; the said spools having their axes of rotation parallel to the said
cylinders and drums and resting on the said drums, tho said cylinders rotating the
drums and with them the said spools, substantially as will be described.
Also, in a series of borizontally placed driving cylinders having their axes of
rotation substantially at right angles to the frame; means to rotate them; the series of
drums resting thereon and adapted to rotate a series of spools by frictional contact ;
combined with a break adapted to arrest the rotation of the drums as the frictional
contact between the drums and cylinders is broken, and with means to move the brake,
substantially as will be described.

page_text: Also, in a driving cylinder; means to rotate it; a drum resting thereon, and a
brake interposed between the said cylinder and drum, combined with means to actuate
the said brake to lift the drum from the cylinder and at the same time check the
rotation of the drum.
I also embody with a driving cylinder, means to rotate it; a drum resting on
and rotated by the said cylinder, slotted spool stands, cheek pieces to hold frictionally
between them and clamp the spools and having journals free to enter and rotate and
slide vertically in the slots in the said spool stands.
Also, in a driving cylinder, means to rotate it, a drum resting thereon and rotated
by the said cylinder and adapted to rotate a spool lying thereon, and spool stands
provided with slots and overhanging flanges to form pockets combined with bearing

automatically when the spool has been filled.
Also, in a driving cylinder, combined with slotted spool stands adapted to receive

The frame work A of suitable shape to contain the working parts, has at one end at
(say) about thirty inches from the floor a bearing and stand A for the power shaft A³
it having a fast and loose pulley as A³ A¹.
The shaft A has at its inner end a pinion A³.
The pinion A engages the pinion B on and rotates the gear shaft B¹, it having
attached to it at suitable intervals bevel gears B2 each of which engages a small bevel
pinion, as a, secured to a transverse shaft a¹ to which is attached near each end a
cylinder as a upon which by gravity rests a drum as or it may be the spool.
As shown in Figures 1. 2 and 3 each cylinder drives a drum, there being a spool 1
resting on each drum, the axes of the cylinders, drums, and spools, being parallel
each to the other and all arranged transversely to the main shaft B¹ and to the length
of the frame, to thus give great compactness of parts, the cylinders, drum, and spools
at opposite sides the frame being preferably in line cach with the other.
The bearing stands a³ for the cylinder shafts.a are secured by bolts a to a
longitudinal rail g.
Each stand as has a V shaped bearing a for one end of a shaft a¹, and a slot 56, see
Fig. 7, for the reception of an adjustable stud a7 which constitutes the fulcrum for the
brake-actuating lever as having at its upper end a toe a, and at its rear side below its
fulcrum a shoulder 8, a shelf 9, and a stop 10, tho said lever having hung upon it a
weight a, see Figure 1, which normally turns the lever to bring the stop 10 against a
depending portion of the stand except when the said lever is held in its full line
position Figure 7, by the spring bolt of the stop motion, as will be described or by
the starting lever 36.
The brake 3, one for each cylinder a² and shown separately in Figure 12 as an open
centred concavo-convex plate, has ears 12, which are pivotted at 13 to cars ^, see
Figure 1, 3, 7, and 8 suitably secured preferably by bolts to the underside of the
permanent rails, the said ears rising past or above the inner edges of the said
rails. Each brake 3 is cast open at its centre to leave a space so that the
cylinder a and drum above it may contact through the said space, the said brake
having two bars or projections 400, 400, which when the brake is interposed between
the cylinder and drum fall at opposite sides in vertical line drawn through the
journals of the drum, and as a result thereof the said brake when lifted, as will be
described, brings the said bar 400, against the drum at opposite sides the said vertical
line and at two points so that the said drum as it is lifted from the cylinder by the
brake is instantly stopped stopping the spool.
Each brake is interposed between a cylinder a² and a drum b, the said drum

page_text: resting by gravity on the said cylinder so long as the brake is permitted to remain in
its lowest position with its beel 613 resting on the lever a, see Figure 7 but as soon as
the spring-bolt of the stop-motion mechanism is pushed out as will be described, to
release its inner end from the shoulder S, of the lever as, the weight a10 turns the said
brake-actuating lover a³, causing its toe a to act upon the heel 613 of and lift the
brako and with it the drum above it thus removing the latter from contact with the
cylinder a which continues to run at speed.
Lifting the drum from the cylinder immediately disconnects the drum from
its source of motion, and at the same time the device which so lifts the drum
acts as a brako to instantly stop the rotation of the drum, overcoming all its
tendency to move by reason of momentum, and as the drum stops the spool stops.
The frame, as herein shown, has extended longitudinally thereof from end to end"
three permanent rails g, having at their longitudinal edges see Fig. 2 flanges or
upright portions which act as stops for stand rails adjustably secured by
bolts extended through slots in the said stand rails g and entering the permanent
rails
Tho stand rails have secured to them by bolts 14 the feet of the spool-stands h, hª,
the lower portions of the stands having vertical grooves 15 see Fig. 5 for the reception
of the journals 16, see right of Fig 3, at the opposite ends of the drums b.
By adjusting the stand rails g' on the permanent rails 7, all the bearing or spool-
stands and all the stands may be moved away from or toward each other in the
direction of the width of the machine to enable spools and drums of different lengths
to be used, as desired, in the same machine.
The upper portions of the spool stands h h', have slots as 17, which receive the
bearing means for the spools, the said bearing incans, as herein shown being the
journals of the weighted check-pieces 3 between two of which the heads or ends of
the spools are clamped, the inner sides of the said cheeks, see Fig. 5, where one
of the checks is shown enlarged having a boss 50 to enter the usual recess at the
centre of the spool-head.
Some classes of spools now employed in spooling and doubling machines, have
as has been stated, metallic hollow journals extended outwardly from their heads,
and to adapt this class of spool for use in my improved machine it is only
recess 58,
necessary to omit the boss 50 and instead provide the cheek with a
to receive the journal ² extending from the spool head. This is shown in Fig. 6.
The friction between the spool and check-pieces is sufficient to rotate both of tho
check-pieces in unison with the spool as the latter is driven by the drum, the
journals turning in the slots 17, and at the same time rising therein as the spool is
filled with yarn, and as soon as the spool has been completely filled the said journals
meet the overhanging edges or flanges 51 at the upper ends of the said stands 18, the
flanges referred to extending substantially across the said slots 17, and the said
journals thereafter pass laterally from the position shown by the first spool at the
right in Fig. 2 into the pocket 18, which is a slot in communication with the slot 17,
the said spool, the said journal having entered the pockets 18, assuming the dotted line
position as shown by the second spool from the right of Fig. 2. and the full line
position Fig. 5 the rotation of the spool stopping as soon as the journals &³ enter the
pockets, after this the spool is removed from contact with the druin.
As soon as the rotation of the full spool ceases, the yarn becomes slack and lowers
the drop wire m³ just as when a thread breaks, and the drop-wire effects the stopping
of the drum.
By an inspection of the drawing, especially Fig. 2, it will be seen that the slot 17 is
inclined from a perpendicular, and that the slot 18 forming the pocket is nearly or
substantially at right angles to it, and it will also be noticed that the slot 17 is of such
inclination and depth that when the bearing means for the spool (as the said journal /³)
is in the lower end of the said slot (as when the yarn is first applied to the spool) that
the said journal occupies a position at the right of the centre of rotation of the drum,
in which position the drum exerts its greatest leverage upon the spool, and it will be
noticed that as the spool is gradually filled, the bearing means therefor is gradually

page_text: forced upwardly in the slot 17, the point of contact between the drum and the mass of
yarn upon the spool gradually approaching a line perpendicular to the axis of rotation
of the journals, and by the time that the spool is filled the bearing means for the spool
arrive at the junction of the slot 17. and the pocket 18, and are immediately forced as
it were into the pocket 18 through the agency of the over-hanging flange 51, covering
the slot 17. and forming part of the pocket 18.
The spool stands or the outermost stand of each pair of stands h¹, are made in
two parts connected or hinged together by a pin as 19, which permits the upper
portion 20 of the said stand to be turned outwardly with its attached check-piece
when it is desired to remove a spool from or to replace a spool between the two cheek-
pieces carried by the said stands hh, the pivotted or hinged portion 20 being normally
held in upright position with its cheek-piece against one head of the spool by a strong
spiral spring 22 connected to a stud near the foot of the stand and to a stud near the
slot 18 see Fig. 1.
The yarn to be wound upon each spool is taken from one or more bobbins, as m³,
or it may be spools, according to the work to be done, and passed over first a guide-
rail m, thence through an eye 23, at the upper end of a drop-wire m³, shown enlarged
in Fig. 4. thence over a sheave, as m³, on a bracket m at the end of a cross arm m
at the top of the frame through the eyes 24 of the wave motion rods and to the
spools.
The lower end of the drop-wire, it having, as shown, two parallel legs, is guided by
a guide 25, composed, as shown, of a metal plate attached to a block 26. secured in
suitable manner to the underside of a plate 64, resting on the top-board n.
The spring bolt of the stop-motion has suitable bearings near each end in which
tho said bolt is free to slide, one of the said bearings being in a stand 27, while the
other bearing is in a hole in the stand a see Fig. 8.
The bolt is normally pressed forward so that its inner end engages the shoulder 8,
of the lever a 9 by a spiral spring as n¹ surrounding the bolt between the stop lug 29
and the stand 27 see Fig. 1. at left.
The bolt has a second stop-lug 30 and a lug 31. to contain a pin on which is pivotted
and is very nearly balanced the tipping lever 32 of the stop-motion, the inner end of
the said lever being but the least trifle heavier than its outer end so that the lever
normally rests with its inner end upon the stop 30, and at such time the inner end of
the said lever is out of range of the ratchet wheel 33 of the stop motion, there being
one such ratchet for each lever 32, the series of ratchets being connected to the stop
motion shaft 34.
The machine has at each side a like shaft 34 each shaft having at its outer end a
sprocket-wheel 52, which is connected by a chain 53 with one of the two sprocket
wheels 54 or 55, one 54 being on the shaft B₁ just outside the frame, the other 55
being on the hub of a pinion 56 driven by the pinion 57 on the shaft B₁ see detail
Fig. 11. the shafts 34 being rotated constantly, so that whenever a drop-wire for any
cause descends upon the outer end of the lever 32, the said lever is tipped to strike the
top 29, and in so doing the rear or inner end of the lever 32 is acted upon by the
ratchet 33, which pushes the bolt longitudinally outward, releasing its end from the
shoulder 8 of the lever as, permitting the weight a to move the lever as described
and lift the brake.
The lever having been liberated, the weight brings the shelf 9 of each lever a³
against the toe of a starting lever 36 pivotted at 37 on a bracket 38. the said starting
lever being connected by a link 39 to a hand piece 40 having a knob A 1 extended
through a slot in the board n, the operator to start any drum pulling the knob
outward, causing the toe of the lever 36 acting on the shelf 9 to turn the lever as until
the shoulder 8 is again caught and held by the bolt f, such movement of the lever
lowering the brake and perimitting the drum 6 to rest on and be rotated by the
cylinder a².
The shaft B at that end of the machine opposite the fast and loose pulley, has a
pinion C, see Fig. 2, which engages and rotates a large toothed gear C¹ loose on a
stud (2, the hub of the said gear having a sprocket-wheel C³ which engages and moves

page_text: a chain d extended over a sprocket wheel (fast on the heart-shaft of the wave
motion, the said shaft having secured to it at suitable intervals one or more heart cams
as, Cone only of which is shown, each heart in its rotation acting on the studs 2, 8,
of a carriage D, provided with rack-teeth 4 and adapted to slide in a guide-way D',
fixed to an upright D² erected on the frame-work.
The stud 2 is fixed to the said carriage, but the stud is projected from a block 5
held to the carriage loosely by a screw 6 extended through a slot in the said block,
the outer end of the block being acted upon by a strong spiral spring 7 located between
the block and an car or lug on the carriage D, the said spring serving to keep the
stud 3 in contact with the heart and prevent any lost motion due to lack of contact of
the heart with the two studs 2 and 3.
The teeth 4 of the carriage engage the toothed end of a sector-lever d' the hub of
which surrounds a stud d' the latter serving as a fulcrum for the said sector-lever.
The lower end of the sector-lever is slotted, see Figure 2 to receive within it an
adjustable roller or other stud p, the latter entering an elongated slot in a stand p',
shown in Fig. 2 and also separately in Fig. 13, the said stand being connected by
screws 44 to the main bar of the waye motion carriage,, the said carriage being
composed essentially of the bar and suitable blocks or shoes, as p³, arranged at
right angles thereto, and adapted to slide in guide-ways p', secured to suitable up-
rights, the sector lever b' in its movements causing the wave motion carriage to be
reciprocated in a straight line transversely across the machine.
The wave-motion carriage has erected upon it, at suitable distances apart, lugs p³
which receive a rod p upon which at suitable intervals by set screws p' are clamped
arms p which at their outer ends have screwed into them the eyes or guides 24 the
said eyes or guides, as herein shown, being composed of wire screwed therein at one
end so as to be screwed out from or into the said arms 28, as may be desired, the
eyes being held in adjustable position by set nuts 45, there being one such bar
for every spool.
The slot in the sector-lever enables the roller or other stud p to be adjusted therein
up or down according as a short or long spool is to be wound.
To avoid injurious effects in the winding which would result if the wave-motion
moved slower while its motion was being changed from one to the other direction, I
have so placed the point of the heart C, or the part of the heart of greatest diameter,
that it acts upon the carriage D to effect the vibration of the sector-lever and the
movement of the wave-motion carriage at the fastest speed desirable just at the
time that the direction of movement of the wave-motion carriage is being reversed.
It will be noticed that the sets of spools driven by the cylinders of each separate
shaft a actuate spools so arranged with relation to each other that their axes of rotation
substantially coincide, one spool being however at one and the other at the opposite
side of the longitudinal centre of the machine.
This arrangement of the spools, and consequently of the driving drums and
cylinders, the drums being on top of the cylinders, enables me to employ one wave-
motion rod for two sets of spools arranged at opposite sides of the machine.
I am aware that guides used for the journals of spools in machines for winding
slivers coming from combing-machines have been provided with vertical slots in
which the journals of the spools rise as the slivers are wound upon them, and that
the said guides near the top of the said slot have been bevelled or inclined backwardly
to form a shelf upon which the spool when filled might be pushed by the operator, as
for instance in English Patent No. 7787 of 1884.
In the said Patent the spool having been filled, the operator has to lift certain
hooked rods from the journals of the said spools, and at the same time depress an arm
or lever, so that the latter acting against the side of the filled spool pushes the same
away from above the winding cyclinder employed to rotate the spool.
In my invention however, the shape of the slots in the spool-stands and the pockets
in communication with them are such that as soon as the spool is filled, the bearing
means for the spool, viz. -the journals of the cheeks, are automatically forced into
the pocket 18, thus removing the spools from the driving drums, and at the same

page_text: time the rotation of the spool and drum is stopped, and so also the driving cylinders
are rotated at uniform or equal speed, instead of at a variable speed.
I have herein shown one very simple form of stop motion mechanism or devices,
but I desire it to be understood that I do not desire to limit my invention to the exact
form of stop motion devices shown, as instead of the said devices I might use any
other suitable well-known form of stop-motion devices; and so also, while I prefer the
form of connecting mechanism herein shown between the heart-cam and the wave-
motion carriage, yet I may employ any other well known forms of devices commonly
employed for such purposes.
In my inventlon the stop-motion devices for all the spools, one at each side of the
frame, are controlled by a single positively driven shaft which through a ratchet
wheel thereon acts upon any one of the spring bolts forming part of the stop-motion
device for each spool.
The spaces below the flanges 51 and formed the pockets 18 in which pockets pass
the bearing means for the spools, are in practice contracted at the outer ends of the
pockets by bending the flanges 51. down at their free ends or between the points 200
& 201. see Fig. 5. so as to prevent the said bearing means from passing out of the
said pockets in the direction of the Arrow 203. except by considerable strain exerted
by the operator, so that the said bearing means when the part 20 is tipped over
remain in the stand-the bearing means when passed into position under the flanges 51.
have to be pushed through the contracted space between the points 200 and 201 with
considerable force, but once in the bearing means will not be forced out by the spool
stands by any force due to the strain acting on the spool.
The stop motion devices, cylinders, drums, spools, and their supporting mechanism
are alike at both sides the frame and I have therefore considered it unnecessary to
duplicate all the said parts in the drawings as from the parts shown anyone con-
versant with doubling or spooling machines will readily understand my invention.
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:
