Improvements in Spinning Machines.
A communication from abroad by EDWARD WRIGHT, of Worcester, in the County of
Worcester, State of Massachusetts, United States of America, Machinist.
1, WILLIAM PHILLIPS THOMPSON F.C.S. M.L.M.E. of the Agency for Foreign
Patent. Solicitors 6, Lord Street, Liverpool & 6, Bank Street, Manchester both in
the County of Lancaster and 823 High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows :—
This invention relates to improvements in spinning machines designed for spinning
wool and similar fibrous material; the same heing more especially adapted to that.
class of machines wherein the roving drums and roving delivering rolls are supported
on a movable beam, or carrier, which travels toward.and from the revolving spindles,
for giving the stretch when spinning, and for winding the yarn upon the bobbins.
The object of this invention is to generally improve and perfect the construction
of the machine, and to provide mechanism of superior efficiency and greater
practical utility for the purposes intended.
In this improved spinning machine, the operating mechanism, disposed in as close
and compact à manner as convenient, is preferably located at a central position.
while the spindles and roving drums are arranged on suitable frames that extend
to the right and left from this central operating head, to a sufficient distance to
accommodate the desired number of spindles.
A back shaft extends throughout the length of the machine, and is provided at
intervals with sprocket wheels and chains, by means of which the roll beam or
roving drum carrier D is moved forward and back. The cylinder shaft, which is
also the driving shafi, extends through the operating head; the band cylinders being
coupled thereto, axially in line at either end, and together running the full length
of the machine. The roll beam D having the roving drums and roving delivery
rolls mounted thereon, extends at either side as far as the rows of spindles, and is
supported by tracks on the tops of the frame. The roll heam is moved towards and
from the spindles, for winding on and giving the "stretch" or draft while spinning
the yarn, by revolution of the back shaft in one direction and the other, as the
spinning operations are effected; the chains at intervals along the machine serving
to keep the roll beam square with the row of spindles as it moves back and forth.
Fallers and counter fällers of well known construction are provided for guiding
the varn onto the bobbins. Said fallers are operated by the faller lock and a cop-
builder mechanism of improved construction.
Pulleys for the driving belt are arranged on the cylinder shaft.
The scrolls are respectively connected by ropes to .drums, wheels or auxiliary
scrolls fixed on the back shaft, to which shaft backward and forward rotative motion
is imparted by the action of the respective scrolls for moving the roll beam from
and towards the spindle. The scrolls turn loose on their respective shafts, and are
provided with clutches operated by levers actuated at the proper time by cams on
a cam shaft, which is mounted in suitable bearings, and is provided with an escape-
ment wheel that acts in conjunction with an escapement lever for stopping and
starting a series of cams mounted upon said cam shaft, for throwing into and out
of operation the various parts of the mechanism.
The various changes in the operation of the mechanism are automatically effected
under control of the cam shaft and its automatic stop escapement. There are five
stops or changes in its revolution. The escapeinent wheel is loose on the shaft and
is provided with five soulders. A dise; fixed upon the shaft adjacent to the escape-
ment wheel, supports a pawl that engages with ratchet teeth on the hub of a gear

page_text: that runs loose on the cam shaft and receives motion from a gear on an operating
shaft. The tail of the pawl projects through the slot in the disc, and is confined
hy a slot in the escapenient wheel. A spring presses against the pawl to force its
tooth into the ratchet. When the escapement wheel is released, the spring presses
forward the pawl causing it to engage the ratchet, and the motion of the constantly
revolving gear is transmitted to the cam shaft which moves one-fifth of a revolution,
or until another shoulder of the escapement wheel strikes the escapement lever,
forces the pawl from the ratchet and allows the ratchet to revolve without moving
the cam shaft, which is held at its position by a star wheel until the escapement
is again released.
The several cams can be of any construction suitable for imparting the required
action, or throwing into and out of engagement the several clutches. The escape-
ment lever is bifurcated at its end, and provided with hardened steel detenis that
engage the escapement wheel. A spring brake is provided to retain the escapement
lever at position of adjustment.
The operator shaft and scroll shafts are rotated by a suitable train of gears. A gear
for "backing off" or reversing the motion of the cylinder and spindles, preparatory
to winding up the yarn, is arranged to be clutched to the driving pulley.
A rocker shaft, supported near the top of the frame, has a series of fingers that
engage with a trip piece on the roll bean as the roll beam approaches the position
thereof, and thus rocks the shaft. Said rocker shaft is also provided with a crank
which is joined by a link with the escapement lever. The action of the rocker shaft
throws the escapement lever from engagement with the escapement wheel, thus
allowing the cam shaft to shift position, bringing into operation the different parts of
the mechanism.
The twist wheel, mounted on a swinging bracket, works in conjunction with a cam
on the cam shaft, by which said twist wheel is; at the proper time, raised to engage its
worm screw, and is provided with a pin that moves into contact with a lug on the
escapement lever for throwing the detent from the escapement wheel, when the proper
degree of twist has been spun into the yarn.
The belt shipper is arranged to be operated automatically from a cam on the cam
shaft, or by hand.
A take-up mechanism for returning the scrolls to position after the clutches are
released, giving tension on the scroll ropes, and compensating for the expansion and
contraction of the ropes due to the variation in the degree of humidity of the
atinosphere, is a feature of the invention, and is made substantially as follows:
at
Winding drums are attached to the respective scrolls. To the peripheries of these
drums a cord, strap, or band is connected, one end being attached to the drum. This
strap passes around a sheave which is connected with a spring that gives pressure
simultaneously and uniformly both ends of the strap; the sheaves allowing the strap
to adjust itself to the strain at either end, and to the action. of the respective scrolls
when winding and unwinding their ropes; consequently giving proper tension on each
of the scrolls, one against the other.
One of the drums is preferably provided with means for taking up or letting out.the
tension strap.
For connecting the scroll rope to the auxiliary scroll, an adjustable rope holding
device is employed, consisting of a collar or hub arranged loose on the shaft adjacent
to the side of the drum or scroll. The inner face is provided with suitable notches to
engage with a lug on the side of the scroll. The scroll rope is carried. through a
notch on the rim of the auxiliary scroll, passed around the periphery of the rope
holder hub. The strain on the scroll rope causes the hub to hug against the auxiliary
scroll, so that the lug and notches on their adjacent faces engage and thereby retain
the rope. This device affords a very simple and convenient means for expeditiously
effecting adjustment of the scroll rope.
For controlling the delivery of roving, there is a loose sprocket wheel provided with
a clutch thrown into and out of action by a lever actuated by one of the canis on the
cam shaft.. Said sprocket wheel operates, by means of a suitable drive chain, a shaft,

page_text: and sprocket wheels, from which drive chains extend to and around guide sheaves near
the front of the machine; said chains passing over and engaging with sprocket wheels
on the ends of the delivery rolls.
That the entire stretch of twisted yarn may be wound onto the bobbins, and that
the succeeding draft may commence with the feed of roving full from the spindle
points, an auxiliary mechanism is employed for starting the roving delivery rolls an
instant before the roll beam reaches the forward limit of movement.
An important feature of the invention consists in combining and constructing the
cop-builder and quadrant mechanisms to operate automatically in conjunction with
each other, so that the devices for winding up the yarn, and the devices for building
or giving shape to the bobbin, are controlled by one set of mechanism, or simul-
taneously adjusted. This feature is believed to be broadly new in spinning machinery.
The cop-builder mechanism is mounted upon a frame or carrier bar, which is supported
by suitable bearings, and motion is imparted thereto by any mechanism that will give
to said carrier bar a backward and forward reciprocating movement.
The rear bearing is made with a flat surface, which is surrounded by a channel and
an upwardly projecting flange for holding a quantity of oil sufficient to cover the
bearing surfaces and give ample lubrication to the parts which are subject to great
pressure at certain stages of the operation.
A rotatable shaft, having the cop-builder adjusting screw and slide adjusting screw
formed thereon, is mounted in bearings on tho carrier. A longitudinally movable cop-
builder plate, also supported on said carrier, is connected by a threaded lug to the
cop builder screw. The top edge of the plate serves as a bearing for a vertically
moving slide to which the cop-forming bar is hinged, on which bar the roll of the cop-
builder lever runs for raising and depressing the fallers.
A shaping lug is attached to the forward end of the builder plate. The front upper
surface is curved or inclined, and engages with a lug that projects from the forward
end of the cop forming bar for lifting said bar; thereby regulating the length of the
winding on of yarn at the base of the bobbin,
A stop lug, adjustably fixed to the carrier, limits the forward movement of the cop-
builder plate, and at each doffing, sets the mechanism at the same position for starting
the bobbins.
The adjusting shaft has, at its forward end, mechanism that causes partial rotation
of the adjusting screw shaft and consequent adjustment of the parts connected
therewith.
An adjustable incline or guide way is attached to the carrier and works on a
horizontal pivot, whereby it is adapted to assume different degrees of inclination, its
rear part being sustained by an adjustable support in connection with a slide block that
moves longitudinally upon the carrier bar. The slide block is screw threaded to
engage the threads of the adjusting shaft, by means of which said slide block is
moved forward and back for raising and depressing the rear end of the hinged guide
way. One of the screw threads along the shaft is made of greater pitch, so that the
slide block runs off from the threaded portion of the shaft, and its movement ceases
at an early stage of the operation, corresponding to the time of forming the base cone
of the bobbin, while the other thread continues to move the cop-builder plate until the
bobbin is filled.
A rod connected to the cop-builder plate serves for drawing the slide into engage-
ment with the screw threads on the adjusting shaft, when the cop-builder plate is
moved to its forward position.
An arm or lever, fulcrumed upon an axis near the back of the machine, carries a
pulley that can be adjusted nearer to or farther from the axis on which the arm
swings for running bobbins of a different size. This arm serves a purpose similar to
that of the part which, in other spinning machines, is known as the "quadrant," and
it is therefore termed the "quadrant arm" by the inventor, although the construction
and operation are quite different from quadrants as heretofore employed. Combined
with this arm, a quadrant operator lever, fulcrumed on the frame, is employed, its
rear end connected to the hub of the arm by a chain or in other equivalent manner;

page_text: while its forward end works in conjunction with the adjustable inclined guide on the
carrier bar which guide lifts and depresses the forward end of the quadrant operator
lever, causing the arm to swing backward and forward.
The winding chain is attached at one end to the winding drum on the cylinder
shaft. It then passes around the pulley on the quadrantarm, thence around a pulley
on the roving beam, and thence to the quadrant arm, to which the end of the winding
chain is attached by an adjustable stul.
When the roying beam approaches the spindles, the quadrant arm swings forward,
releasing the winding chain; the degree of such release being governed by the action
of the quadrant operator in conjunction with the adjustable inclined guide way and
adjusting, shaft on the cop-huililer carrier. The adjusting screw shaft on the carrier
controls boil the cop-builder and the winding mechanism, hence the cop-builder
devices and the winding devices will properly and proportionately coincide in their
relative action under any and all circumstances. This is a very important feature,
which, so far as the inventor is aware, has never before been attained in any spinning
machine wherein backing off and winding is a part of the operation.
The adjustment and regulation of the quadrant operating devices are automatic and
positively in unison with the adjustment and regulation of the cop-builder, either
when moving inward, or while being returned to starting position. The quadrant
operator can be connected to the quadrant arm by gear teeth in lieu of a chain, or
otherwise.
Another feature of the invention consists in an automatic take-up, which acts on
the winding chain and serves for effecting the tighter winding of the yarn upon lic
mose of the bobbin. This mechanism consists of a swinging lever carrying at its end
a guide pulley, over which the winding chain passes, while its other end is connected
to an actuating bar furnished with means for engagement with a detent connected!
with the roll beam. The forward end of the actuating bar is sustained by a hearing
on the arm of a lever, centrally fulcrumed on a suitable support, and the other end of
said lever is connected by a link with the cop-builder arm, or to a spring bar attached
to said cop-builder arm. The cop-builder arm, as it follows the action of the builder
bar, effecis elevation of the ratcheted end of the actuating har, causing its engagement
and movement with the detent on the roll beam. When the detent engages the
lever, it lifts the pulley and causes an extra pull on said winding chain, and a
quickened action of the spindles just at the instant the yarn is being wound on at the
nose of the bobbin; thus tightening the winding of the yarn at such point.
Another feature of the invention comprises the improved mechanism for easing-in
the roll beam to accommodate the shortening of the strands of yarn by the twisting,
For this a worm gear is employed, having a crank which is connected by a chain and
rod with a balance lever mounted upon a screw threaded hub on the back shaft. Upon
the side of the lever is a pin that engages a stud on the auxiliary scroll; or, if in any
case preferred, upon a separate disc or arm fixed to the back shaft in lieu of the scroll.
The hub of the lever is screw-threaded, and fitted in such manner that rotation of tlie
shaft causes a movement of the lever toward and from the auxiliary scroll. This
movement is sufficient to bring the parts into engagement when the rope is wound
upon the draft scroll, and to carry the paris away from each other at other revolutions
of the back shaft. The easing-n is effected by the crank depressing the forward end
of the lever, and lifting the lug against the lug of the auxiliary scroll, thereby causing
slight forward rotation of the back shaft sufficient to move the roll beam forward as
the yarn shortens by twisting.
The means for producing friction for winding up the chain upon the winding drum
is a feature of the present invention. From an auxiliary shaft a belt is arranged
around the winding druan; and a loose swinging lever is provided with a pulley and
with a counterweight to cause friction of the belt upon the drum sufficient to wind up
the chain when the roll beam moves backward, but not enough to prevent the drum
slipping within the belt by the draft on the chain when winding the yarn.
The faller lock is provided with a backwardly extending bar, the end of which is in
position to engage the escapement lover when the faller lock is drawn back. Said bar

page_text: has a lng which is engaged by an upright lever, the lower end of which is pivotted to
the bed frame, while its upper end is in position to engage the roll beam or its shoe
when at its forward position. In its forward movement the roll beam strikes the
upright lever to throw off the faller lock at the instant the roll beam reaches its
forward position.
For preventing the counter faller from rising while backing off, a lever, having its
forward end connected with the counter faller, is employed. The rear end of the lever
is engaged by the roll beam, so that the counter faller is positively held depressed so
long as the roll beam is in contact with the lever; but when the roll beam approaches
the spindles said lever is freed and the counter faller is released for doing its work.
The clock or indicator is operated by means of a ratchet and pawl connected with a
bar to which movement is imparted by an incline or cam surface, one step, more or
less, at each movement of the roll beam by the end of the bar sliding up the
incline.

This invention relates to improvements in spinning machines designed for
spinning wool and similar fibrous material; the same being more especially adapted
to that class of machines wherein the roving-drums and roving-delivering-rolls are
supported on a movable beam, or carrier, which travels toward and from the
revolving spindles, for giving the stretch when spinning, and for winding the yarn
upon the bobbins. The object of this invention is to generally improve and

In the improved spinning machine, the operating mechanism, disposed in as close
and compact a manner as convenient, is preferably located at a central position, while
the spindles and roving-drums are arranged on suitable frames that extend to the
right and left from this central operating head, to a sufficient distance to accommodate
the desired or any given number of spindles. As this extension and multiplication
of spindles and drains will be well understood, only a few of the spindles are shown
in the present drawings, as in Fig. 1.
Referring to parts, A denotes the main frame, upon which are bearings for
supporting the various shafts and operating parts. B indicates the back-shaft which
extends throughout the length of the machine, and is provided at intervals with
sprocket-wheels B carrying chains D2, by means of which the roll-beam or roving
drum-carrier D is moved forward and back. O indicates the cylinder-shaft, which
is also the driving-shaft and extends through the operating-head the band-
cylinders e being coupled thereto, axially in line at either end, and together
running the full length of the machine. The roll-beam D, having the roving
drums and roving-delivery-rolls E-mounted thereon, extends at either side as
far as the rows of spindles, and is supported by tracks or guide-ways a on the
tops of the frames A, it being provided with suitable bearing-shoes that slide along
said guide-ways.
Sindicates the spindles supported in bearings along the front of the frame, and
rotated by bands run from the cylinder c. The roll-beam is moved towards and
from the spindles for winding in and giving the "stretch" or draft while spinning

page_text: the yarn, it being operated by the chains or bands D' which are fixed to said beam
and pass around the sheaves or sprocket-wheels B and around guide-wheels
supported on suitable brackets near the spindles, so that revolution of the back-
shaft B, in one direction and the other, moves the roll-beam, roving-drums and
delivery rolls bodily to and from the spindles as the spinning operations are effected.
The chains D2 are arranged at intervals along the machine, and serve to keep the
roll-beam squaro with the row of spindles as it moves back and forth.
Fallers and counter-fallers of the well known construction are provided for
guiding the yarn onto the bobbins. Said fallers are operated by the faller-lock F,
and a cop-builder mechanism, which latter is of improved construction, as will be
hereinafter explained.
The pulleys G, G1, G2, for the driving-belt, are arranged on the cylinder-shaft C.
The pulley G is fixed or keyed upon the shaft C. The pulley G is provided with
a long sleeve or hub and runs loose on the shaft C, and has a pinion G fixed to the
end of its hub. The pulley G² runs loose upon the hub of pulley G₁ and serves as
the loose pulley on which the belt runs when the machine is idle. A large gear G
is also mounted on shaft C, which is adapted to clutch with pulley G by means of a
friction rim and is arranged to be thrown into and out of clutch by a lever actuate.l
by one of the cams on the cam-shaft.
i
H indicates the operator-shaft, I the cam-shaft, J the draft-scroll, and K the in-
drawing-scroll. The scrolls are respectively mounted on shafts J and K', and are
connected by ropes j and k to drums, wheels or auxiliary scrolls M and N fixed on
the back-shaft B, to which shaft backward and forward-rotative motion. is imparted by
the action of the respective scrolls, when moving the roll-beam from and towards the
spindle by the chains D2, as above specified. The scrolls J and K are mounted to
turn loose on their respective shafts, and are provided with clutches J and K that
connect them with their shafts for action, which clutches are operated by levers
actuated at the proper time, by cams on the cam-shaft I, which is mounted in
The cam-shaft is
suitable bearings, and is operated from the shaft H by gears H².
provided with an escapement-wheel I' that acts in conjunction with an escapement
lever L for stopping and starting said cam-sbaft, and a series of cams are mounted
upon said cam-shaft for throwing into and out of operation the various parts of the
mechanism at proper times. A star-wheel 1 is fixed on the shaft 1, ana presser-
bar St having a roll S2 is combined therewith and serves to hold the shaft and cuns
from revolving, except when worked by the escapement.
The various changes in the operation of the mechanism are automatically effected
under control of the cam-shaft I and its automatic stop-escapement.
There are five
stops or changes in its revolution. The escapement-wheel is loose on the shaft and
is provided with five shoulders or notches. A disk I is fixed upon the shaft
adjacent to the escapement-wheel, and upon said disk there is supported a pawl that
engages with ratchet-teeth H fixed on the hub of a gear 12 that runs loose on the
cam-shaft and receives motion from the gear H' on the shaft H. The tail of the pawl
projects through the slot in the disk, and is confined by lugs or a slot in the
escapement-wheel. A spring h³ attached to the disk presses against the back of the
pawl to force its tooth into the ratchet H³. When the escapement-wheel is released,
the spring presses forward the pawl causing it to engage the ratchet and the motion
of the constantly revolving gear 1 is transmitted through the pawl and disk to
change the position of the cam-shaft and cams fixed thereon; which moves one-fifth
of a revolution, or until another shoulder of the escapement-wheel strikes the
escapement-lever; this stops the movement of the escapement-wlieel, and its lugs,
acting against the tail of the pawl, forces the pawl from the ratchet and allows the
ratchet to revolve without moving the cam-shaft, which is held at its position by
the star-wheel I until the escapement is again released, when another one-fifth
revolution is effected. The form of the several cams, has not been herein particularly
described but it will be understood that said cams can be of any construction suitable
for imparting the required action for throwing into and out of engagement the
several clutches and operated parts. The escapement-lever L is bifurcated at its end,

page_text: and provided with hardened steel detents or lugs that engage the ratchets of the
escapement-wheel 1, and having an arm I projecting from the side thereof, as
shown.
By making the escapement-lever with the bifurcated head, an outside
ratchet for the estapement-wheel, can be used and the five stops or notches, can be
readily filed to correct form, and the removable detents can be given greater wearing
surface, and be made to change position from one side to the other as the edges
become worn, thus making a much more serviceable construction than where the
escapement ratchet works on a simple pin or dog, and the ratchets are formed within
a groove of the escapement disk. A spring-brake L is provided to act upon the
arm L' of the escapement-'ever to retain it at position of adjustment.
The operator-shaft H and scroll-shafts. J and K are rotated by a suitable train, of
gears. In this train of gearing (see Fig. 27) the gear G₁ operates an auxiliary-
shaft Q beneath the cylinder-shaft by meshing into an intermediate gear that in
turn meshes with the pinion Q fixed on said auxiliary shaft. Said shaft carries a
gear Q³ that meshes with gear H on the operator-shaft H, which latter shaft carries
the gear that meshes with the gear I on the cam-shaft I. The gear H¹ on the
operator-shaft meshes with the gear K on the shaft K of the in drawing scroll K.
The shaft is also provided with a gear Q that meshes with the pinion Gou the
end of pulley G. A pinion C² fixed on the cylinder-shaft C meshes with a gear V
mounted on a stud on the side of the frame A, which gear carries a pinion Vithat
meshes with a gear J on the end of the draft-scroll-shaft J.
The gear G is for "backing off" or reversing the motion of the cylinder and
spindles, preparatory to winding up the yarn; the motion being transmitted to said
gear after it has been clutched to pulley G through the gears G³, Q, Q, and Q, while
the belt is running on the second pulley G.
R indicates a rocker-shaft, supported in bearings upon and near the top of the
frame A, and extending parallel with the guide, a along which the roll-beam D
travels. Said rocker-shaft has a series of fingers R, R, R³ that engage with a trip-
piece d, connected with the roll-beam which crowils the fingers to one side, as the
roll-beam approaches the position thereof, and thus rocks the shaft. Said rocker-
shaft is also provided with a rigid arm or crank R, the outer end of which is joined
by a link or rod with the horizontal arm L' of the escapement-lever L. The action of
the rocker-shaft throws the detents of the escapement-lever L from engagement with
the notches of the escapement-wheel I, ilius allowing the cam-shaft I to shift the
position of its cams, bringing into operation the different parts of the mechanism
accordingly as the trip-piece d strikes the respective fingers in the movement of the
roving-carrier.
Tindicates the twist-wheel mounted on a swinging-bracket T having an arm that
works in conjunction with a cam on the cam-shaft, by which said twist-wlieel is, at
the proper time, raised so as to engage, for its operation, with a worm-screw T on the
auxiliary shaft Q. Said twist-wheel is provided with a pint that moves into contact
with a ling or projection T3 on the arm of the escapement-lever L for throwing the
detent from the escapement-wheel when the proper degree of twist has been
spun into the yarn.
The belt-shipper W is supported on a reciprocating rod w, and arranged to be
operated automatically by the lever W from a cam 18 on the cam-shaft I; or to be
operated by hand by the lever W in connection with the inclined cam W on a
rod, W which extends along the front of the machine, and is provided at intervals
with suitable handles for turning it.
The take-up mechanism for returning the scrolls to position after the clutches are
released, giving tension on the scroll-ropes, and compensating for the expansion and
contraction of the ropes due to the variation in the degree of humidity of the atmo-
sphere, is a feature of the invention, and is made substantially as follows Winding-
wheels or drums J and K³ are attached to the respective scrolls J and K. To the
peripheries of these drums a' cord, strap, or hand O is connected, one end being
attached to the drum J and the opposite end to the drum K³.
This strap passes
Lover guide-sheaves 0 and around a sheave or pulley O' which is connected with a

page_text: spring 03 that presses downward the pulley 03 and thereby gives pressure simul-
taneously and uniformly at both ends of the strap; the sheaves or pulleys allowing
the strap to adjust itself to the strain at either end, and to the action of the respective
scrolls when winding and unwinding their ropes; consequently giving proper
tension on each of the scrolls, one against the other; and holding the ropes and k
uniformly taut at all times; while the yielding of the spring 0³ compensates for any
variation in the take-up of rope by the scrolls, or for any expansion or contraction
of the ropes that may be occasioned by climatic changes. The sheaves 0¹ are
arranged to run loose on a cross-bar or shaft at the back of the frame, so that they
offer no resistance to the free action of the tension mechanism. In the present
instance the spring O³ is arranged as a heavy wire coiled around a cross-bar A² at
the lower part of the frame; the centre portion of the spring being extended back-
ward, and provided with a hook that engages the supporting block of the pulley 02;
the opposite ends of the wire are held by lugs on the bed-plate A. (See Fig. 16.)
Any other suitably arranged spring can be employed for giving equivalent action on
the band O, if preferred.
One of the drums. J³ is preferably provided with means for taking up or letting out
the tension-strap 0; and inay be constructed as indicated in Figs. 17 and 18. In
this a ratchet-wheel J' is fixed on the end of the scroll J, while the drum J³ is
arranged to turn loose on the hub of said scroll, or its shaft, and a pawl Je is pivoted
on the side of the drum that engages with the teeth of said ratchet-wheel, it being
held thereto by a suitable spring. By turning forward the drum, while the scroll and
its ratchet-wheel are held stationary, the pawl slips over the notches and the strap is
wound up more or less upon the drum, and held from turning back by the engagement
of the pawl. For letting out the strap or loosening the tension the pawl is lifted by
ineans of a small lug that projects from its side, when the ratchet can be turned back
the required number of noiches, and the pawl again allowed to drop into engagement
for holding it at that position.
For connecting the scroll-rope k to the auxiliary scroll N, an adjustable rope-
holding device (see Figs. 12, 14, and 15) is employed consisting of a collar or hub N
having a rope grip or prongs that adapt it for retaining the knotted end of the
scroll-rope; which collar is arranged loose on the shaft adjacent to the side of the
drum or scroll N. The inner face of said rope-holder is provided with suitable
notches or ratchets n' to engage with a lug n on the side of the scroll. The scroll
rope & is carried through a notch n on the rim of the auxiliary scroll N, and passed
around the periphery of the rope-holder hub, it's knotted end being inserted between
the prongs n.
The strain on the scroll-rope causes the knot to be drawn firmly into
the recess between the prongs n, where it is held fast, and also causes the rope-holder
hub to hug against the side of the auxiliary scroll, so that the lug and notches on
their adjacent faces engage and thereby retain the rope-holder and rope-end securely
at position of adjustment. If it is desired to lengthen or shorten the rope, it can be
done by simply sliding the rope-holder hub outward on the shaft B sufficiently to
relieve the lug ² from the notch n¹, and then turn the rope-holder on its axis to
wind up or slacken the rope to the extent required; then again allow it to be drawn
up against the side of the scroll. This device affords a very simple and convenient
means for expeditiously effecting adjustment of the scroll-rope; and obviates the
necessity of re-tying the holding knot at the end of the rope. The adjustable rope-
holding device in combination with the scroll and scroll-rope, is a feature of the
invention.
The mechanism for controlling the delivery of roving is as follows:-On the shaft J'
there is a loose sprocket-wheel "P provided with a clutch Pl arranged to be thrown
into and out of action by a lever actuated by one of the cams on the cam-shaft I.
Said sprocket-wheel operates, by means of a suitable drive-chain p, a short shaft P²,
at the back of the frame, and is provided with sprocket-wheels P³ from which drive-
chains Pextend to and around guide-sheaves P near the front of the machine; said
chains P passing over and engaging with sprocket-wheels fixed on the ends of
the lower delivery rolls E'.

page_text: The drums D for supporting the spools of roving are geared to receive their
movement from the roving-delivery-rolls in well-known manner; the gearing being
at the ends of the machine and in the present instance not shown. During the time
that the clutch P is thrown in, and the sprocket-wheel P is in action, the shaft P
operates the chains P, and the roving-delivery-rolls are rotated for feeding off the
rovings, but when the clutch P is thrown off, the friction on the rolls being
greater than that on the other parts of the mechanism, the chains P are carried
along with the sprocket-wheels E without causing rotation of the rolls E, since the
roll and shaft P are at such time free to turn loose on their axes, and are easily
carried around by the backward movement of the chains P.
In order that the entire stretch of twisted yarn may be wound onto the bobbins, and
that the succeeding draft may commence with the feed of roving full from the spindle
points, an auxiliary mechanism is employed for starting the roving-delivery-rolls an
instant before the roll-beam D reaches the forward limit of movement. This
mechanism consists, in the present instance, of paris arranged substantially as shown
in Figs. 21 to 24. In this the sprocket-wheel E on the end of the roving-delivery-
roll E' is provided with an internal ratchet e (see Fig. 24) and adjacent thereto,
mounted to run loose on the end of the roll-shaft, is a disk or wheel E, which carries
a pivoted pawle³ that engages the ratchet e in a direction for turning the rolls E E
forward. Upon the periphery of the disk E is wound a chain or band E, one end of
which is connected to the disk, while the other is connected to a swinging arm E,
the upper end of which is pivoted to a standard D fixed on the roll-beam D. Con-
nected to, and winding upon the hub of the disk E' is a strap d², the outer end of
which is attached to a spring D, as indicated. This spring and strap serve for
returning the disk E and pawl e to normal position, and for winding the chain E
upon the disk.
A suitable Inge is formed on the side of the swinging-arm E,
and an adjustable stop-dog a is attached to the frame A for engagement with
said Jug.
In the operation, when ilie roller-beam approaches the spindles the dog a³ coming
in contact with the lug e arrests the arus E and causes draft upon the chain E' which
effects motion of the disk, and the pawl, by engaging the ratchet e causes slight
rotation of the roving-delivery-rolls before the roll-beam reaches its forward limit of
movement; thereby feeding off sufficient roving to reach from the rolls E to the
points of the spindles S, before the carrier or roll-beam changes its direction of
movement. When the roll-beam is moved back the arm E is released from the stop-
dog, and the disk, chain, and pawl are returned to their normal position by the action
of the spring D and strap d'. The disk E' and arm E are held stationary while the
roving rolls are operated by the chain P, the movement being then such as to carry
the ratchet-teeth e of the wheel E past the pawl e³ without engaging it. This part of
the invention, comprising the auxiliary starting mechanism for giving feed of roving
before the starting up of the spindles, can be omitted in machines for spinning some
grades of stock, if desired; or, the devices can be made non-operative by simply
shifting the dog a³, so that it will not engage the lever or arm E. The machine will
then run without the action of the auxiliary roving-feed. Usually however, it is
preferable to use the auxiliary feed-mechanism as above described.
The attaching plate of the stop-dog is best slotted so that said dog can be adjusted
forward or back for giving a longer or shorter are of movement to the lever and pawl,
and a consequent variation of the amount of advance feed imparted to the rovings.
The auxiliary starting mechanism may be employed on only one of the lines of
roving-delivery-rolls, as the rolls of the opposite line, or at the other side of the
operator-head, will be started by the power and motion transmitted from the first
operated wheel E through the chains P and sprocket-wheels P³.
An important feature of the invention consists in combining and constructing the
cop-builder and quadrant mechanisms to operate automatically in conjunction with
each other, so that the devices for winding up the yarn, and the devices for building
or giving shape to the bobbin, is controlled by one set of mechanism, or simultaneously
adjusted. This feature is believed to be broadly new in spinning machinery. The best
"

page_text: mechanisni now devised by my correspondent for carrying out this part of the invention
is substantially as follows: The cop-builder mechanism is mounted upon a frame or
carrier-bar 10, which is supported by suitable bearings, and provided with a toothed
rack 9. Reciprocating motion is imparted thereto by a pinion 11 connected by a
short axle with a sprocket-wheel 12 which is rotated, alternately in one direction and
the other, by a drive-chain 13 from a sprocket-wheel on the back-shaft B, or by any
mechanism that will impart to said carrier-bar equivalent backward and forward
reciprocating movement.
The rear bearing or bed S is made with a flat surface on which the bearing-boss of
the carrier 10 slides, and this surface is surrounded by a channel and an upwardly
projecting flange 7, as shown in Fig. 6, thus forming a receptacle for holding a
quantity of oil sufficient to cover the hearing surfaces and give a constant and ample
lubrication to the parts; which are, in the action of the machine, subject to great
pressure at certain stages of the operation.
The backward movement of the carrier 10 is performed during the time the yarn is
being wound on the bobbin. A rotatable shaft 14 having the cop-builder adjusting-
screw 15 and slide-adjusting screw 16 formed thereon, mounted in bearings on the
carrier 10 and the longitudinally movable cop-builder-plate 17, also supported on
said carrier, is connected by a nut or threaded lug 18 to the cop-builder-screw 15:
whereby said plate 17 is moved backward or forward along the carrier when the
adjusting shaft is turned in its bearings. The top edge of the plate 17 is made
with a short level portion at its rear end, forward of which is a long incline,
which level and inclined portions serve as a bearing for the pin cr lug. 19 that
supports the vertically moving slide 20, which works up and down in suitable guide-
ways on the carrier-bar; the slide being raised or lowered accordingly as the plate 17
is at forward or rearward adjustment, or at some intermediate position. The cop-
forming-bar 21 is hinged to the top of the slide 20, and in connection with the top
surface of said slide, forms the track on which the roll of. the cop-builder-lover or
arm X runs for raising and depressing the fallers. The hinge by which the bar 21
is connected to the slide 20 has its axle in line with the top surface on which the
roll travels, and is also at the junction of the backward and forward inclines; the
backward incline being stationary on the slide 20, while the forward incline, which is
on the bar 21, can be adjusted up or down. An adjusting-stud. or screw 28 is best
arranged in the top of the slide 20, beneath the forming-bar 21, by means of which
the relation of the cop-forming-bar can be adjusted for giving more or less inclination
to its top surfaces. The hinging of the cop-builder-bar in the manner described,
affords facility for varying the winding at the point of the cone on the bobbin to
make a longer or shorter taper in the winding, without changing the other parts,
or without change in the winding at the shoulder of the bobbin. A shaping-lug
or cam-plate 22 is attached to the forward end of the builder-plate. The front
upper surface of said can-plate is curved or inclined and engages with a lug that
projects downward from the forward end of the cop-forming-bar 21 for lifting said
bar; thereby regulating the length of the winding on of yarn at the base of the
bobbin until the bobbin is filled to its maximum circumference. The curve or cam-
surface of the lug 22 is formed to give a rapid descension of the cop-forming-bar at
the commencement of the bobbin, and then to gradually decrease the movement. A
stop-lug 24, adjustably fixed to the carrier, is preferably provided for limiting the
forward movement of the cop-builder-plate 17, so that the attendant can, at each
doffing, set the mechanism at the same position for starting the next set of bobbins.
The adjusting-shaft 14 has, at its forward end, a pulley 25 working loose thereon,
and carrying a pawl 26 which engages a ratchet-wheel 27 fixed on the end of said
shaft. A chain 26 passes over and is attached to said pulley; one end thereof being
secured to an arm 29 pivoted to a bracket attached to the floor, or other stationary
position, while a weight 30 is attached to its other end for rotating the pulley and
taking up the slack of the chain when the carrier-bar 10 is moved backward. A
sheave 31 is mounted on a suitable stud at the forward end of the carrier, which sheave

page_text: runs onto the chain 28 as the carrier 10 moves forward; and by drawing down said
chain partially rotates the pulley 25, at which time the pawl 26 engaging the teeth of
the ratchet 27 causes partial rotation of the adjusting-screw-shaft 14 and consequent
adjustment of the parts connected therewith.
An adjustable incline or guide-way 32 is attached to the carrier 10 and works on a
horizontal pivot, whereby it is adapted to assume different degrees of inclination, its
rear part being sustained by an adjustable support or hinged brace 33 in connection
with a slide-block 34 that moves longitudinally upon the carrier-bar, on which it is
confined by suitable guides. The slide-block 34 is screw-threaded, as a nut, to
engage the threads 16 on the end of the adjusting-shaft 14, by means of which said
slide-block is moved forward and back for raising and depressing the rear end of the
hinged guide-way 32. The slide-block 34 can, when desired, be adjusted to move
past the dead centre, or beyond the position at which the brace 33 stands vertical, (see
dotted lines in Fig. 6) so as to slightly lower the inclined guide 32 after it has reached
its highest position.
pro-
The screw-thread 15 that moves the cop-builder-plate is comparatively fine in
portion to the screw-thread 16 at the end of the shaft; the former having a pitch of
about eight to the inch, while the latter has a pitch of about three to the inch, more
or less; consequently the slide-block is moved much more rapidly than the cop-builder
plate by revolution of the shaft. The screw-threads 16 are of less extent along the
shaft than are the threads 15, as well as of greater pitch; so that the nut or slide-
block 34 runs off from the end or threaded portion of the shaft, and its backward
movement ceases at an early stage of the operation the limit of such action corre-
sponding to the time of forming the base cone of the bobbin, while the thread 15
continues to move the cop-builder-plate until the bobbin is filled.
A rod 35 connected to the cop-builder-plate 17 extends backward through an
opening in the slide-block 34, and has upon its screw-threaded end beyond the slide-
block, adjusting nuts, as indicated. Said rod serves for drawing the slide-block
forward and into engagement with the screw-threads on the end of the adjusting-
shaft, when the cop-builder-plate is moved to its forward position. The adjustment of
the nuts on the end of this rod 35 are preferably such that whon. the cop-builder-
plate 17 is moved forward so that the junction point between its inclined and level top
is beneath the pin 19 of the vertical moving slide 20, the slide-block 34 will be at a
position where its screw-threads will commence to engage the screw-threads 16 on the
end of the shaft.
The end of the adjusting-shaft 14 is squared or fitted to receive a wrench or handle
for running the cop-builder-plate, slide-block and inclined guide-way back to their
first or starting positions after a set of bobbins has been filled and preparatory to
commencing a new set of bobbins.
An arm or lever 40 is fulcrumed upon an axis near the back of the machine
(in the present instance upon the back girt or rod A³ that connects the frame A)
in a manner to swing back and forth. On its lower part said arm carries a pulley 41,
revolvable on a suitable stud which is preferably secured in a slot in the arm, so that
the pulley can he adjusted nearer to or farther from the axis on which the arm swings.
This adjustment is for the purpose of making cops or bobbins of larger or smaller
diameter adjustment toward the centre or axis on which the arm swings giving a
smaller diameter of bobbin, and vice versa. No change in the position of the pulley-
stud is made except it is desired to change the machine for running bobbins of a
different size. The lever 40 serves a purpose similar to that of the part which, in
other spinning machines, is known as the "quadrant," and it will therefore be termed
the " quadrant-arm," although the construction and operation is quite different from
quadrants as heretofore employed.
Combined with the arm 40, and actuated from the incline 32, a quadrant-
operator 38 is employed, which preferably consists of a crooked lever, fulcrumed on
a shaft or axis A² fixed on the frame A, for action substantially as indicated. The
rear end of the lever 38 is connected to the hub of the arm 40 by a chain 39, or in

page_text: other equivalent manner: while its forward end works in conjunction with the
adjustable inclined guide 32 it being preferably provided with an anti-friction
traveller or shoe 36 that slides on the guide-way 32. When the carrier-bar 10 moves
forward the inclined guide lifts the forward end of the quadrant-operator-lever 38,
causing the arm 40 to swing backward, as indicated in dotted lines Fig. 4. Then
when the carrier-bar moves backward the quadrant-operator moves down the inclined
guide-way and permits the quadrant-arm 40 to again swing forward. The guide-
way 32 is best provided with an oil well 37 at its lower end, as shown in Fig. 7, into
which the end of the shoo 36 dips when at its lowest position, and from which it
carries up, as it moves back along the guide, a quantity of oil sufficient for lubricating
the surface on which said shoe travels.
The winding-chain 44 is attached at one end to the winding-drum C³ on the
cylinder-shaft C. It then passes around the pulley 41 on the quadrant-arm, thence
around a pulley running on a stud fixed to the roving-beam D, and thence extends
to and is attached to the upper end of the quadrant-arm. The end of the winding-
chain is attached to the upper end of the quadrant-arm by an adjustable stud at 42,
by means of which the tension for winding the nose of the bobbin can be increased or
diminished. By carrying said stud farther from the axis on which the quadrant-armi
swings, the mechanism is caused to wind the nose of the bobbin fighter; and by
carrying the stud nearer to the axis the mechanism is caused to wind less tight.
When the roving-beam D approaches the spin-lles the quadrant-arm with the
pulley 41 swings forward, releasing the winding-chain; the degree of such release
being governed by the action of the quadrant-operator in conjunction with the
adjustable inclined guide-way and adjusting-shaft on the cop-builder carrier.
The chain 39 which connects the quadrant-arm and operator-lever is best provided
with an adjusting book or link, the shank of which is screw-threaded and connected
with the lever in a manner to facilitate the lengthening and shortening of the
connection; so that the parts can be relatively adjusted to compensate for wear; for
the stretch of the chains by use, or for bringing the parts into proper relation when
setting up the machine.
The ratchet-wheel 27, at the end of the adjusting-shaft 14, is interchangeable with
wheels having different numbers of teeth for spinning different numbers or size of
yarns said wheels varying their numbers of teeth froin eight to thirty, more or less,
as desired; the lesser number of teeth being employed for the coarse sizes, while
the greater number are employed for the fine sizes of yarn. The screw-shaft. 14
controls both the cop-builder and the winding mechanism, hence the simple change
of the ratchet-wheel 27 is all that is required for adapting the cop-builder and
winding devices for working any of the various sizes of yarn which it is desired to
spin and the cop-builder devices and the winding devices will properly and pro-
portionately coincide in their relative action under any and all circumstances.
This is a very important feature which, so far as my correspondent is aware, las
never before been attained in any spinning machine wherein backing-off and winding
is a part of the operation.
By combining the cop-builder mechanism with the quadrant and winding
mechanism so that both are simultaneously controlled by the same adjusting-shaft or
screw-spindle, as herein set forth, the advantage is attained of a positive uniformity
of operation on different sets of bobbins, and all numbers of yarn, since the adjust-
mment and regulation of the quadrant-operating devices is automatic and positively
in unison with the adjustment and regulation of the cop-builder, either when
moving inward, or while being returned to starting position; and the quadrant
adjustment is not left to the caprice of the attendant while filling the base of the
bobbins. '
In the modification shown in Figs. 25 and 26, the manner is illustrated in which
teeth
the quadrant-operator 35 can be connected to the quadrant-arm 40 by gear
in lieu of the ebain 89. In this the quadrant-operator is extended and fitted to
carry a toothed segment 39' that meshes with a toothed segment formed on or attached
to the hub of the quadrant-arm 40. The segment 39 can be made longitudinally

page_text: adjustable by screws 38', or otherwise, so as to bring the arm 40 and operator-
lever 36 into proper relation with reference to the inclined guide 32 and winding-
chain 44. In Fig. 26 a manner is illustrated of connecting the quadrant-arm 40
and quadrant-lever 3S by a chain from the forward end of said operator-lever. In
this the chain 39 is fixed to a stud 392 that is adjustable in a slot at the forward
end of the operator-lever, and from thence passes beneath a guide-sheave 353 fixed to
the stationary bed or frame and up to the hub of the quadrant-arm 40. In each of
these modifications the inclined guile 32 imparts similar action to the arm 40 by the
reciprocation of the cop-builder carrier 10.
Another feature of the invention consists in an automatic take-up which acts on the
winding-chain 44 and serves for effecting the tighter winding of the yarn upon the
nose of the bobbin. This mechanism (see Figs. 2 anil 19) consists of a swinging
lever 46, carrying at its lower end a sheave or guide-pulley 47, over which the
winding-chain 44 passes, while its upper end is connected to an actuating bar 48
which is furnished with an inclined ratchet or series of notches or means for engagement
with a detent or lug 49 fixed on or connected with the roll-beam D. The forward end
of the actuating bar 48 is sustained by a stud, roll, or bearing on the arm of a lever 50,
centrally fulcrumed on a suitable support-bracket or projecting part of the frame A;
the other end of said lever being connected by a chain or link 51 with the rear end of
the cop-builder-arm X or preferably as in the present instance, to the end of a
spring-bar 52 attached to said cop-builder-arm, as indicated in Fig. 19. Depression of
the rear end of the cop-builder-arin as it follows the action of the builder-bar mechanism,
effects a corresponding elevation of the ratcheted end of the actuating bar 48,
causing when at sufficient height, its engagement, and movement to a greater or
less extent, with the detent 49 on the roll-beam D. When the detent 49 engages
the bar 48 and carries it forward, the lever 46 lifts the pulley 47 against the
chain 44, and causes an extra pull or strain on said winding-chain (see dotted
lines Fig. 19) and a quickened action of the spindles just at the instant the yarn
is being wound on at the extreme point or nose of the bobbin; thus tightening the
winding of the yarn at such point. When commencing, and while filling the hody
of the bobbins, the bar 48 is depressed so low that its ratcheted end is not engaged
by the detent 49; the parts being ordinarily adjusted so that this mechanism is
brought into action only for the completion or final finishing of the bobbins.
Another feature of the invention comprises the improved mechanism for easing-in.
the roll-beam D to accommodate the shortening of the strands of yarn by the
twisting, For this a worm-gear 54 is employed mounted on a swing bracket
having a spring-bar 55 which works in conjunction with a cam I on the cam-
shaft I, for raising said wheel into mesh with a worm 56' on the shaft K'. Said
worm-wheel has a crank which is connected by a chain and rod 57 with a balanced
lever 58 mounted upon a screw-threaded hub 59 fixed on the back-shaft B. (See
Figs. 3, 11, and 13.) The lever 58 has a counter-weight 60 to lift the rod, chain,
and crank, and to return the worm-wheel 54 to normal position when it is thrown
out of engagement with the worm 56. Upon the side of the lever is a pin or
lug 61 that engages, at the proper time, with a stud 62 on the side of the auxiliary
scroll Mor, if in any case preferred, said stud can be upon a separate disk or arm
fixed to the back-shaft B in lieu of the side of the scroll. The bub of the lever 58
is screw-threaded and fitted to the hub 59 in such manner that rotation of the
shaft B causes a movement of the lever longitudinally upon shaft B toward and from
the auxiliary scroll (see dotted lines Eig. 12). This movement is sufficient to bring
the lug 61 into engagement with the stud 62 when the rope is wound upon the
draft-scroll J, and to carry the parts away from each other so that the lug 61 escapes
the lug 62 at other revolutions of the back-shaft B.. The operation of easing-in is
effected at the time the lugs are brought into engagement with each other, at which
time the worm-wheel 54 is in mesh with the worm 56, it being lifted up by its arm 55
in contact with a cain on the cam-shaft. The crank on the worm-wheel draws down
the connecting-rod 57, depressing the forward end of the lever 5S, and lifting the
Ing 61 against the lug 62, thereby causing slight forward rotation of the back-shaft B

page_text: sufficient to move the roll-beam D forward as the yarn shortens by twisting, and
previous to the in-drawing movement for winding up the spun yarn. The lever 58 is
preferably slotted, as at 63, (see Fig. 13) to facilitate the adjustment of the stud 6.1,
so that it will engage with the stud 62 at the proper instant. The connecting pivot 64
is made adjustable towards or from the fulcrum, thus affording facility for varying
the extent of the easing-in action by varying the leverage so that the stud 61 moves
in a longer or shorter arc. The rod 57 is best provided with means for lengthening
or shortening the connection.
The clutch for connecting the winding-drum to the cylinder-shaft is substantially
as heretofore employed; but the means for producing friction for winding up the
chain upon said drum is a feature of the present invention. Upon the auxiliary
shaft Q, below the cylinder-shaft C, I arrange a pulley 70 from which a belt 71 is
carried around the winding-drum C and mounted on said auxiliary shaft is a loose
swinging lever 72, one arm of which is provided with a pulley 73 which runs
against said belt 71 for tightening it upon the drum and its pulley, while the other
end of the lever is provided with a counter-weight 74 for pressing the tightener
pulley against the belt. The counter-weight 74 is given enough preponderance to
cause friction of the belt on the druin sufficient to wind up chain 44 when the roll-
beam moves backward, but not enough to prevent the drum slipping within the
belt by the draft on the chain 44 when winding the yarn.
To the side of the faller-lock F is pivoted a backwardly extending bar 76, the
rear end of which is in position to engage the lug on the escapement-lever L when
the faller-lock is drawn back under the roll X* of the cop-builder-arm X. Projecting
from the side of said bar is a lug or pin 78 which is engaged by a plate 79
adjustably fixed upon the side of an upright lever 80, the lower end of which is
pivoted to the bed-frame at 81, while its upper end is in position to engage with a
lug or arm that projects from the roll-bean or its shoe when at its forward position.
In its forward movement the roll-beam. strikes the upper end of said upright lever
to throw off the faller-lock F from the roll X at the instant the roll-beam reaches
its forward position.
The plate 79 upon the lever 80, which engages the lug 78, can be adjusted for
causing the faller-lock to be thrown off at the proper instant of time.
The backing-off clutch 82 and filler-lock chain 83 are of well known construc-
tion and are arranged to operate in the well known manner. The drawing up of
the chain $3 and locking of the faller-lock on the roll X2 of the cop-builder-arm X
forces back the escapement-lever L by means of the arm 76, and throws the lug h
off the escapement-wheel ratchet, at which time the action of the cam-shaft I brings
into operation the in-drawing-scroll.and winding mechanisms.
For preventing the counter-faller from rising while backing-off, and while the
roll-beam D is at rearward position, a device is employed which consists of a
lever 85, fulcrumed at 86 to a suitable support on the frame of the machine, and
having its forward end connected by a cord or chain 37 with the counter-faller,
said chain being pussed under a guide-sheave 90, as indicated in Fig. 27. The rear
end of the lever 85 is shaped with a suitable cam or inclined surface, which is
engaged by the roll-bean D, or a detent attached thereto when said roll-beam is at
backward position, thereby holding the lever depressed at its rear end and the con-
sequent elevation of its forward end, which draws down the chain passing beneath
the sheave, so that the counter-faller is positively held depressed so long as the
roll-beam D is in contact with the lever; but when the roll-beam approaches the
spindle, said lever is freed and the counter-faller is released for doing its work while
winding the yarn on the bobbins.
The clock or indicator 95 for denoting the runs of yarn may be of any suitable
construction; in the present instance it comprises a rotating graduated dial mounted
within a suitable case on a vertical axial stud, and provided with gear-teeth that
engage with a worm-screw on a horizontal arbor furnished with ratchet mechanism
whereby motion is imparted to the dial. An index-point, fixed on the case, extends
onto the graduated circle for denoting the degree of movement of the dial. Said clock

page_text: is supported upon the roll-beam over one of the guides a, on which said roll-beam
travels, and is operated by means of a ratchet and pawl 96; the pawl being connected
with a bar 97 to which movement is imparted by an incline or cam surface 98 formed
in the guide a, (see Fig. 28) into which the end of the bar. 97 drops when the
roll-beam approaches the limit of its forward movement, and is subsequently lifted
as the roll-beam moves backward, so that the pawl is actuated for operating the
indicator mechanism, one step more or less at each backward movement of the roll-
beam by reason of the end of the bar 97 sliding up the incline 98..
The operation of the improved spinning machine is as follows:-Commencing
with the roll-beam, ata position near the spindles, and just starting for spinning a
stretch. The driving-belt at this time is on the first pulley G and second pulley G¹,
thus operating the cylinder and spindles, and also the shaft E. The clutch of the
draft-scroll J is in mesh for action, and also the clutch P for driving the mechanism
whereby the roving is delivered. As the roll-beam D moves backward, the roving is
paid out by the delivery rolls E until the trip depresses the finger R' thereby
moving the rocker-shaft R and escapement-lever L, throwing the detent from the
shoulder of the escapement-wheel I and permitting the first change in the position
or partial revolution of the cam-shaft I. At this change the cam I throws off the
clutch J and stops the delivery of the roving. When the roll-beam roaches its back-
ward limit the trip d depresses finger R2 on the rocker-shaft again moving the
escapement-lever from a notch and allowing the cam-shaft to make its second change
in position. At this time the cam, 1 releases the clutch J2 and throws the draft-
scroll J out of action, and the cam I raises the twist-wheel T into mesh with the
worm on the shaft Q, and the cam I" brings the easing-in mechanism into action.
The machine then runs on until sufficient twist has been imparted to the yarn, when
the pint of the twist-wheel strikes the inclined bracket T3 and moves the escapement-
lever, releasing a notch of the escapement-wheel and permitting the third change in
the position of the cam-shaft.
At this third change, the cam 110 throws off the twist-wheel which drops from the
worm, and is turned back to place by the weight and chain, and at the same time
the cam 18 operates the lever W and shipper W to shift the driving-belt from the
pulley G, so that it will run on the pulley G; also at the same time the clutch G
is brought into engagement for operating the mechanism that turns the cylinder
backwards for backing-off the spindles.
It will be understood that the driving-belt at all times runs upon and operates the
pulley G, and that in shifting from pulley G to pulley G³ the belt is moved across
said central pulley so that its edge will lap onto either one or the other of the
pulleys G or G, while at the same time embracing the pulley G. The backward
rotation of the cylinder winds up the faller-lock chain 83, drawing the faller-lock F
beneath the roll of the cop-builder arm X, and said faller-lock as it comes into
position pressés back the rod 76 against the escape lever L which releases another
notch of the escapement and effects the fourth change in position of the cam-shaft.
At this fourth change the cam 1 throws in the clutchi K of the indrawing scroll K,
by which the back-shaft is operated to move forward the roller-beam. At the same
time the cam throws off the friction-gear G and stops the backing-off action; and
the cam 1 releases its lever and permits the operation of an actuating spring that
throws into engagement the winding-drum-clutch which has been held out of mesh
during the previous action.
As the roller-beam moves forward, the chain 44 unwinds from the drum C³, and
the cylinder and spindle S are thereby revolved for winding the yarn upon the
bobbins. The form of winding on the yarn is controlled by the cop-building
mechanism, acting through the faller-lock and fallers ff, which latter in a general
way operate substantially in the well known manner.
When the roller-beam, reaches its forward position the trip d strikes the stop
finger R³ of the rocker-shaft, thereby swinging the escapement lever from the last
notch of the escapement-wheel and permitting the fifth change in the position of the
cam-shaft, bringing said cam-shaft around to its original position. At this change the

page_text: cami 1 throws off the winding-drum clutch; the cam 1' throws off the clutch of
the in-drawing scroll; and the cam 15 operates the belt-shipper which shifts the belt
from the pulley G over onto the pulley G; the cam 13 throws in the clutch P* of the
roving feed mechanism, and the cam I throws in the clutch of the draft-scroll; thus
bringing the parts to their original position, when the operation as above described
will be repeated.
If the attendant at any time desires to stop the mechanism, he rotates the shipper-
rod W which by drawing back the lever W moves the shipper so that the belt is
shifted entirely onto the loose pulley G.
