Improvements in Machinery for Making Organzine or Silk Warp, in
which the Single Threads are Twisted, Doubled, and Re-twisted
by a Continuous Operation.
I, JOSEPH E. TYNAN, of No. 304 Ellison Street, Paterson in the County of Passaic
and State of New Jersey, United States of America, Machinist do hereby declare
the nature of this invention to be as follows:-
The present invention is a modification of, and improvement upon the device for
which Letters Patent No. 8535 were granted to me in Great Britain, June 14th 1887,
and a reference is hereby made to the Specification of the said patentfor such parts
and their mode of operation as are described herein.
The frame of the machine, the spindle rail and longitudinal frame are of ordinary
character and the driving shaft is provided with a drum or range of pulleys. I
prefer to have one pulley for each pair of belts that pass to opposite groups of
spools.
The spindles occupy triangular positions as in aforesaid patent, there being in
each group of spindles, two spindles from which the thread is supplied and a
spindle upon which the thread is wound, and the ring rail is made to rise and fall as
the winding of the thread proceeds.
The threads from the supply spools are twisted by the revolution of their
spindles and laid together by the revolution of the third spindle in the opposite
direction.
The threads pass from the supply spools up against guide fingers and aro
wrapped around them to give the proper tension by the revolution of the spools and
spindles.
The driving roller is upon a shaft that receives its motion from the driving shaft
through suitable gearing.
The feed roller is upon a shaft and the ends thereof are supported in brackets, and
there is a starting lever pivoted upon one of said brackets, and passing below the
feed roller shaft near one end thereof.
All the parts before named correspond to those set forth in my said patent
No. $535 and do not require further description herein: 1 however remark that
there are not any loose pulleys on the spindles, and the driving roller is made as a
cylindrical shell with mortices through the shell instead of recesses cut into the surface
of the roller.
I do not make use of a guide roller, in front of the feed roller, but I employ a
traverse bar reciprocated longitudinally by suitable means such as by a crank pin and
link or connecting rod. The crank pin is at the upper end of a shaft, in bearings
upon one of the frames and receives motion from a worm wheel on the shaft acting
upon the gear wheel on the shaft. By this means the traverse bar receives a small
end wise reciprocation sufficient to move the threads as they draw over the respective
fingers and prevent such threads wearing grooves in said fingers.
The fallers instead of occupying nearly a horizontal position as usual stand nearly
vertical above the pivots on which they swing. The hooks of the fallers extend
forwards from the pivots and they are nearly counterpoised by the weight portions of
each faller, which extend to the rear of the pivots. By this construction the leverage
of the hook causes the faller to descend when a thread breaks and in so doing the
weight portion of the faller is moved over the pivot and increases rapidly the efficient
action of the faller in moving the stop mechanism, but when the parts are in a
normal position there is but little pressure of the faller against the thread.
The threads after they leave the guide fingers aforesaid pass up behind and over

page_text: a thread support preferably in the form of a glass rod upon a standard that is fastened
to the faller stand or frame, and then the threads pass under the hooks of the fallers,
and go over a standing guide finger to a porcelain roller or guide upon the traverse
bar where they come together, and from there they go around the feed roller and
pass down in front of the arm of the detector near to or against the shaft of othe
driving roller and through a fixed guide to the ring traveller and spool upon which
the doubled thread is wound.
To allow for this way of leading the thread, the feed roller does not coincide in
position with the driving roller, but the end portion of the feed roller projects
beyond the end of the driving roller, hence there is ample room for the introduction
of the detector, which is placed just below the feed roller, and brings the stop motion
into action in case the thread leaving the roller becomes entangled with that portion
of the thread on the roller as sometimes, occurs when there are knots or rough places
on the threads. If there were nothing to stop the parts at such a time, the feed
roller would draw the thread from the back bobbin as well as from the front ones,
and lap them around itself. This danger I entirely avoid, for when the thread leaving
the roller becomes entangled with the thread on the roller, the angle of the thread
below the roller is changed which allows the arm of the detector to fall forward and
cause the stop mechanism to be brought into action as hereinafter described.
At the back end of the starting lever a hanging latch is pivotted and a link hangs
from the stud which is to the rear of the latch pivot so that the weight of said link
and parts of the stop motion therewith connected or a weight upon the said link
may tend to swing the lower end of the latch towards the longitudinal frame and
the faller stand that is bolted upon such frame. A shoulder on the latch rests upon
the back end of the faller stand when the parts are in the normal position, and
when the stop motion is brought into action the latch is pushed backwardly to move
said shoulder off the faller stand and allow the parts to drop, and a projection on
the latch limits the downward motion, and a finger on the latch in front of the link
before mentioned prevents the latch being swung too far back by the action of the
stop mechanism hereafter described.
When the latch and link descend, the starting lever is raised at the front end and
the feed roller lifted to stop the feeding of the threads.
The faller stand is made with a bracket projection at the front end forming jaws
for the pivots of the fallers.
These fallers are made as vertical weights slightly to the rear of the pivots on
which they swing, so as nearly to counterpoise the weight and leverage of the hook
ends of the fallers, thus causing the fallers to hear very lightly on the threads and
prevent the danger of the faller moving and carrying the thread with it and stopping
the action when a thread has not broken, but as soon as a thread breaks and the
faller hook moves away from.the thread support the efficiency of the same in bringing
into action the stop mechanism is increased, because the weight of the faller acts
with increase leverage as it descends towards a horizontal position, and there is a
projecting finger on the faller to act upon a rocking lever when the threads break
and the faller descends.
↑
This rocking lever is pivotted in a swinging yoke that is within a mortice in the
faller stand and is pivotted to the latter. The rear end of this lever is the heaviest
so that in a normal position it rests upon a projection on the faller stand and upon
the rocking lever is a stud or .claw that comes into one of the mortices in the driving
roller, whenever one of the fallers descend, and, the said driving roller acts against
the claw to move the rocking lever endwise, the said yoke swinging while this
movement takes place, and the back end of this rocking lever pushes the latch so
that it passes off its,support and the link aforementioned and stop mechanism descend
to stop the action of the belt that rotates the group of spindles as hereafter described.
As the rocking lever is inoved backward and unlatches the latch, such latch falls
and carries down with it the rear end of the said rocking lever and thereby keeping
the claw before referred to clear from the driving roller, and simultaneously the
aforesaid yoke'swings forward again by its own weight carrying with it the rocking

page_text: lever and returning it to the normal position, but the rocking lever cannot rise again
by the weight of the faller to cause the claw to come into contact with the driving
roller because a flange upon the latch remains above the rear end of the rocking lever
until said latch is raised to start the parts.
The detector is pivotted upon the faller stand and it stands nearly vertically and
the wire thereof is behind the threads as they are laid together and pass down from
the feed roller. When the detector falls forward, a finger that projects from the
lower part of the detector in below the rocking lever raises such rocking lever and
causes the claw thereon to engage the driving roller and bring into action the stop
mechanism. This operation takes place whenever the doubled thread breaks or
whenever the threads become entangled and commence to wind on the feed roller
as before described, or whenever the thread slackens in consequence of a ring traveller
being thrown off.
It will now be apparent that when the attendant has mended a thread and he
is about to start the parts, he places one finger under the front end of the rocking
lever to prevent the weight of the fallers moving said lever and bringing the claw
again into contact with the driving roller and then with the thumb the outer end of
the starting lever is depressed to start the driving mechanism of the spindles, and to
bring the feed roller into contact with the driving roller, and the other hand of the
operator is free to guide the threads to place as they are drawn up, and there is no
separate operation required to pass the threads into the hooks of the faller wires,
because it is only necessary to guide the threads as they draw up, and cause
them to pass in below the hooked ends of the faller, and lead off between them to the
finger.
The revolutions of the supply spindles and spools wrap the threads around the
guide fingers before mentioned and the revolution of the spool upon which the doubled
thread is wound throws the descending thread within the stationary guide hook, and
the operations proceed automatically.
The movement end wise of the traverse bar and its guides is sufficient to traverse
the threads slightly upon a standing guide finger and the feed roller and against the
detector wire and driving roller shaft and stationary guide hook and prevent the
said parts becoming worn into grooves or notches. These parts are horizontal and
parallel to each other at the portions where the thread touches them, so that the thread
can be traversed freely upon them.
If the swing yoke before mentioned is dispensed with the rocking lever can be
pivotted upon the faller stand; in this case the claw of the rocking lever will
be made with a pusher that slides in supports on the rocker lever. so that the pusher
and claw will be moved together by coming into contact with the end of one of the
mortices in the driving roller to act upon the latch and stop mechanism. In this case
a spring is used to return the pusher and claw to their normal position. The parts of
the fallers and detector remain unchanged.
The driving belt passes around the respective pulleys of the group of spindles as
in aforesaid patent, but the tightener pulley acts in connection with the stop
mechanism, the lever of said pulley being suspended by the link before mentioned,
hence when the latch and link are raised by the starting lever the belt is tightened
and when the latch is pushed back and drops until its flange rests on the back end
of the rocking lever the tightener pulley is lowered and the belt loosened, and it
becomes incapable of driving the spindles, but there would be a slow movement by the
friction of the parts were it not that I apply a brake to the respective pulleys and
spindles.
employ a brake plate similar to that shewn in aforesaid patent; this plate is
adapted to occupy the space between the three triangular placed spindles, and it is
below the pulleys upon said spindles and rests upon the tapering upper part of the
spindle sockets or upon projections thereon, and the lever of the tightener pulley has
an end that passes in beneath the middle of said brake plate so that when the
tightener pulley is lowered and the belt slackened, the brake plate is lifted 'into

page_text: contact with under sides of the spindle pulleys and they are stopped by the
friction.
Upon the brake plate at one side of the machine is a finger or stud to prevent the
slack belt slipping off the pulley adjacent to it, but I find that at the other side of
the machine the lever near the end that passes beneath the brake plate serves this
purposon
9 1
the levers of the tightener pulleys there are guide fingers to prevent the belts
slipping off said tightening pulleys.
The parts at the two sides of the machine that act with the respective groups of
pulleys are alike with the exception of the fingers or studs and guides for the
belts.
It will be apparent that the parts of the stop motion will not be changed in their.
mode of operation, if the force required to unlatch the catch or latch before referred
to is derived from a separate shaft instead of from the driving roller and its shaft.
This can be done by providing the rocking lever with a lateral and rearward projection
or continuation that passes at one side of the latch the outer end of said projection
having at or near its end a claw to be acted upon by a cam or tooth on a revolving
shaft in a convenient position for giving the required movement to the parts when a
faller or detector acts on the rocking lever.
The projection or claws against which the revolving device acts to give end motion
to the rocking lever and liberate the stop motion, may be varied according to the
character and location of the revolving device without altering the mode of operation
of the parts.
Upon the brake plates aforementioned there are curved fingers, that pass over the
edges of the respective spindle pulleys, so that the pulleys are free to revolve with-
out touching these fingers, but when either spool or bobbin is pulled off its spindle,
said spindle cannot become detached because the overhanging finger limits the upward
movement of the spindle and its pulley. A vertical guide pin attached at its upper
end to the brake plate serves to guide said plate, and a cross pin or head
at the lower end of the pin forms a stop to prevent the brake plate being lifted too
high.

Improvements in Machinery for Making Organzine or Silk Warp, in
which the Single Threads are Twisted, Doubled, and Re-twisted,
by a Continuous Operation.
I, JOSEPH E. TYNAN, of No. 304 Ellison Street Paterson in the County of
Passaic, and State of New Jersey, 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 —
The present invention is a modification of and improvement upon the device for
which Letters Patent No. 8535 were granted to me in Great Britain June 14 1887
and a reference is hereby made to the said patent for such parts and their mode of
operation as are set forth herein.
In the drawings
i
Fig. 1. is a vertical cross-section of the spindle rail and frame and elevation of the
spools and parts at one side of the machine."
Fig. 2. is a front elevation of one group of spools and parts acting with them.
Fig. 3. is a plan view showing two groups of spindles, one at each side of the
machine and the belts for driving the same.

page_text: Fig. 4. is an elevation of the belts and mechanism for driving and stopping the
spindles.
Fig. 5. is a modification of the stop-mechanism actuated by the fallers.
Fig. 6. is a plan view in larger size of the rocking lever and faller stand, the
fallers and detector being in section.
Fig. 7. is a detached elevation of the detector and parts acting with it, and
Fig. 8. is a detached view of the brake plates and the device for holding down
the pulleys and spindles.
The frame A. spindle-rail B. and longitudinal frame C. are of ordinary character
and the driving shaft 1. is provided with a drum 2. or range of pulleys. I prefer
to have one pulley for each pair of belts that pass to opposite groups of spools.
The spindles 3. 4. and 5. occupy triangular positions as seen in fig. 3. and the ring
rail 9. is made to rise and fall as the winding of the thread proceeds upon the
spool 8. The spools 6. and 7. on the spindles 3. and 4. supply the threads which are
twisted by the revolution of the spindles and laid together by the revolution of the
spindle 5. in the opposite direction.
The threads pass from the spools 6. and 7. up against the guide fingers 66. and are
wrapped around them to give the proper tension by the revolution of the spools and
spindles.
The driving roller 13, is upon a shaft 14. and receives its motion from the
shaft 1. through suitable gearing such as the wheels 16. 18 and 19 and pinions 15
and 17.
The feed roller 11. is upon the shaft 56. and the ends thereof are supported in the
brackets 55. and there is a starting lever 80. pivoted upon one of said brackets 55.
and passing below the shaft 56. near one end thereof.
All the parts before named correspond to those set forth in my said patent
specification No. 85357 and do not require further description herein. I however
remark that there are not any loose pulleys on the spindles and the driving roller 13.
is made as a cylindrical shell with mortices 74. through the shell instead of recesses
cut into the surfaces of the roller.
I do not make use of a guide roller in front of the feed-roller, but I employ a
traverse bar 24. reciprocated longitudinally by suitable means such as by a crank-
pin 2 and link or connecting rod 26. The crank pin 25. is at the upper end of a
shaft 27. in bearings upon one of the frames A. and receives motion from a worm
wheel 28. on the shaft 14. acting upon the gear wheel 29 on the shift 27. By this
means the traverse bar 24. receives a small end wise reciprocation sufficient to move
the threads as they draw over the respective fingers and prevent such threads wearing
grooves in said fingers.
The fallers instead of occupying nearly a horizontal position as usual, stand nearly
vertical above the pivots on which they swing. The hooks 37 of the fallers extend
forwards from the pivots and they are nearly counterpoised by the weight portions
of each faller which extend to the rear of the pivots. By this construction the
leverage of the hook causes the faller to descend when a thread breaks and in so
doing the weight portion of the faller is moved over the pivot and increases rapidly
the efficient action of the faller in moving the stop mechanism, but when the
parts are in a normal position there is but little pressure of the faller against the
thread.
The threads after they leave the guide, fingers 66. pass up behind and over a
thread support 35. preferably in the form of a glass rod upon a standard 36. that is
fastened to the faller-stand 42. or frame, and then the threads pass under the
hooks 37. of the fallers and go over a standing guide finger 38. to the porcelain
roller or guide a upon the traverse bar 24. where they come together and from there
they go around the feed roller 11. and pass down in front of the arm of the
detector 64 near to or against the shaft 14. and through the fixed guide 82. to the
ring traveller and spool 8. To allow for this way of leading the thread, the feed-
roller 11. does not coincide in position with the driving roller 13. but the end portion
of the feed-roller 11. projects beyond the end of the driving-roller 13. hence there

page_text: .
is ample room for the introduction of the detector which is placed just below the
feed-roller and brings the stop motion into action in case the thread leaving the roller
becomes entangled with that part of the thread on the roller as sometimes occurs
when there are knots or rough places on the threads. If there were nothing to stop
the parts at such a time, the feed-roller would draw the thread from the back bobl.in
as well as from the front ones and lap them around itself. This danger 1 entirely
avoid for when the thread leaving the roller becomes entangled with the thread on
the roller the angle of the thread below the roller is changed to the position shown
by dotted lines in fig. 7. which allows the arm of the detector to fall forward and
causes the stop mechanism to be brought into action as hereafter described.
At the back end of the starting lever 80 the hanging latch 40, is pivoted and the
link 50. hangs from the stud 41. which is to the rear of the latch pivot so that the
weight of the link 50. and parts of the stop-motion therewith connected, or a weight
upon the link 50. as seen at 95. may tend to swing the lower end of the
latch 40. towards the frame C. and the faller stand 42. that is bolted upon such'
frame C.
The shoulder 43. on the latch 40. rests upon the back end 44. of the faller stand 42.
when the parts are in the normal position, and when the stop-motion is brought into
action the latch 40. is pushed backwardly to move the shoulder 43. off the part 44.
and allow the parts to drop and the flange 45. limits the downward motion and the
finger 46. being in front of the link 50. prevents the latch 40. being swung too far
back by the action of the stop mechanism hereafter described. When the latch 40.
and link 50. descend, the starting lever 80. is raised at the front end and the feed
roller 11. lifted to stop the feeding of the threads.
The faller stand is made with a bracket projection at the front end forming jaws.
for the pivots of the fallers 60 & 61.
These fallers are made as vertical weights slightly to the rear of the pivots on which
they swing so as nearly to counterpoise the weight and leverage of the hook ends 37
of the fallers, thus causing the fallers to bear very lightly on the threads and prevent
the danger of the faller moving and carrying the thread with it and stopping the
action when a thread has not broken, but as soon as a thread breaks and the faller
hook moves away from the thread support 35. the efficiency of the same in bringing
into action the stop-mechanism is increased, because the weight of the faller acts with
increased leverage as it descends towards a horizontal position, and there is a
projecting finger 62. on the faller to act upon a rocking lever 65. when the threads.
break and the faller descends. This lever 65. is pivoted at 63. in the swinging yoke 67°
that is within a mortice in the faller stand and is pivoted to the latter at 68.
The rear end of this lever 65. is the heaviest so that in a normal position it rests
upon the part 44. and upon the lever 65. is a stud or claw 69 that comes into one of
the mortices in the driving roller 13. whenever one of the fallers descends and the
said roller 13. acts against the claw to move the rocking lever 65. endwise the said
yoke 67. swinging while this movement takes place and the back end of this lever 65.
pushes the latch 40. so that the shoulder 43. passes off its support and the link 50
and stop mechanism descend to stop the action of the belt that rotates the group of
spindles as hereafter described.
As the rocking-lever 65. is moved backward and unlatches the latch 40. such
latch falls and the flange 45. carries down with it the rear end of the said rocking-
lever 65. thereby keeping the claw 69. clear from the driving roller, and simul-
taneously the yoke 67. swings forward again by its own weight carrying with it the
rocking lever 65. and returning it to the normal position, but the rocking lever can
not rise again by the weight of the faller to cause the claw to come into contact with
the driving roller because the flange 45. remains above the rear end of the rocking
lever until the latch 40. is raised to start the parts.
The detector 64. is pivoted at 70. upon the faller stand 42. and it stands nearly
vertical and the wire thereof is behind the threads as they are laid together and pass
down from the feed roller 11. When the detector 64. falls forward a finger 71. that
. projects from the lower part of the detector in below the, rocking lever 65. raises

page_text: such rocking lever and causes the claw 69. to engage the roller 13. and bring into
action the stop mechanism. This operation takes place whenever the doubled thread
breaks or whenever the threads become entangled and commence to wind on the
feed-roller as before described, or whenever the thread slackens in consequence of a
ring traveller being thrown off.
It will now be apparent that when the attendant has mended a thread and he is
about to start the parts, he places one finger under the front end of the rocking
lever 65. to prevent the weight of the fallers moving said lever 65. and bringing the
claw again into contact with the roller 13. and then with the thumb the outer end of
the lever 80. is depressed to start the driving mechanism of the spindles, and to bring
the feed roller 11. into contact with the driving roller 13. and the other hand of the
operator is free to guide the threads to place as they are drawn up and there is no
separate operation required to pass the threads into the hooks of the faller wires
because it is only necessary to guide the threads as they draw up and cause them to
pass in below the hooked ends of the fallers and lead off between them to the finger.
The revolution of the spindles 6. and 7. wrap the threads around the guide
fingers 66. and the revolution of the spool 8. throws the descending thread within
the stationary guide hook 82. and the operations proceed automatically.
The movement end wise of the traverse bar 24. and guide a is sufficient to traverse
the threads slightly upon the standing guide finger 38. and the feed roller 11. and
against the detector wire 64. and shaft 14. and fixed guide 82. and prevent the said
parts becoming worn into grooves or notches. These parts are horizontal and parallel
to each other at the portions where the thread touches them so that the thread can be
traversed freely upon them.
If the swing-yoke 67. is dispensed with the rocking-lever 65. can be pivoted upon
the faller stand as shown in fig. 5: in this case the claw 69. will be made with a
pusher 75. that slides in supports on the rocker lever 65. so that the pusher and claw
will be moved together by coming into contact with the end of one of the mortices in the
roller 13, to act upon the latch 40. and stop-mechanism. In this case a spring 76. is
used to return the pusher and claw to their normal position. The parts of the fallers
and detector remain unchanged.
The belt 30. passes around the respective pulleys 93. 94. 95. of the spindles 3. 4.
and 5. as in aforesaid patent specification, but the tightener pulley 32. acts in con-
nection with the stop mechanism, the lever 33 of said pulley 32. being pivoted at 34
and suspended by the link 50. hence when the latch 40. and link 50. are raised by
the starting lever 80. the belt is tightened and when the latch 40. is pushed back
and drops until its flange 45. rests on the back end of the rocking-lever, the
pulley 32. is lowered and the belt loosened, and it becomes incapable of driving
the spindles but there would be a slow movement by the friction of the parts were
it not that I apply a brake to the respective pulleys and spindles.
employ a brake-plate 51. similar to that shown in the specification of the
aforesaid patent; this plate is adapted to occupy the space between the three
triangular placed spindles 3. 4. and 5. and it is below the pulleys 93. 94. and 95. and
rests upon the tapering upper part of the spindle sockets or upon projections
thereon, and the lever 33, has an end that passes in beneath the middle of the
brake-plate 51. so that when the pulley 32. is lowered and the belt slackened; the
brake-plate 51. is lifted into contact with the under sides of the pulleys 93. 94. 95.
and they are stopped by the friction.
Upon the brake-plate 51. at one side of the machine is a finger or stud 52. to
prevent the slack belt slipping off the pulley 94. but I find that at the other side
of the machine the lever near the end that passes beneath the brake-plate serves this
purpose.
یا
Upon the levers 33. there are guide-fingers 54 and 55. to prevent the belts slipping
off the tightening pulleys 32.
The parts at the two sides of the machine that act with the respective groups of
pulleys are alike with the exception of the fingers or studs and guides for the belts as
seen in figs. 3 and 4. •

page_text: It will be apparent that the parts of the stop-motion will not be changed in their
mode of operation, if the force required to unlatch the latch 40. is derived from a
separate shaft. instead of from the driving, roller 13, and shaft. 14. An illustration of
the manner in which this, can be done is shown in fig. 7. wherein the rocking lever 65.
has a lateral and rearward projection or continuation that passes at one side of the
latch 40 and has at or near its end the claw 69 to he acted upon, by a cam or tooth
on a revolving shaft o' in a convenient position for giving the required movement to
the parts when a faller or detector acts on the rocking lever.
The projection or claws against which the revolving device acts to give end motion
to the rocking lever and liberate the stop-motion may be varied according to the
character and location of the revolving device without altering the mode of operation
of the parts.
Upon the brake-plates 51. there are curved fingers 58. that pass over the edges of
the respective spindle pulleys so that the pulleys are free to revolve without touching
these fingers, but when either spool or bobbin is pulled off its spindle, said spindle
can not become detached because the over-hanging finger limits the upward move-
ment of the spindle and its pulley.
A vertical guide-pin 59. attached at its upper end to the brake-plate 51. serves to
guide said plate and a cross-pin or head at the lower end of the pin 59. forms a stop
to prevent the brake-plate being lifted too high.
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
First. The combination with the driving roller 13. and the feed-roller 11. and
their respective shafts, of the lever 80. a hanging latch pivoted to the end of said
lever 80. a support for the shoulder upon the latch, the link 50. hung to the rear
upper part of the latch, the driving mechanism for the spindles and the mechanism
for stopping the same and the fallers and intermediate mechanism substantially as
specified for moving the shoulder of the latch off its support when the stop-mechanism
is to be brought into action, substantially as set forth.
Second. The combination with the feed roller 11, and the driving-roller 13. of the
faller-stand, the fallers pivoted upon the stand, the rocking lever 65. against which the
fallers act, and the lever 80. and latch, and the claw for the roller to act upon in
giving motion to the latch, substantially as set forth.
Third. The combination with the faller-stand and the feed and driving rollers, of
the fallers pivoted to the faller-stand, the rocking-lever and its claw, the detector
having a finger that acts upon the rocking-lever, the lever 80. and the latch 40.
pivoted to said lever 80. substantially as and for the purposes set forth.
Fourth. The combination with the faller stand, the feed and driving rollers, the
rocking lever, lever 80. and latch, of pivoted fallers each having the hooked end
projecting in one direction above the pivot and a nearly vertical counterweight
above and at the other side of the pivot, so that the hooked end bears with but little
pressure on the thread and the power of the faller increases as it descends, substantially
as specified.
Fifth. The combination with the starting lever, of a latch pivoted at its upper
end to the starting-lever, the link 50. pivoted to the latch at the rear portion thereof,
so that the weight tends to move the latch towards its support, the fallers, feed and
driving rollers and intervening mechanism for acting upon the latch substantially as
set forth.
Sixth. The combination with the spindles a driving drum and belt, a tightener
