Improvements in Thread-winding or Spooling Machines.
1. WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 machine which embodies this invention is intended for automatically winding
thread upon spools and it performs the following operations upon each one of a series
of spools.
(.) The spool is transferred from a hopper to a spindle which spindle at this time
is not rotating.
(b) The spool is wound with thread layer upon layer each succeeding layer
being longer than the preceding one to fill up to the diverging spool heads.
(c) The loose end known as the scrap end which is left projecting when the
winding commences is cut off.
(d) When the spool is filled the winding stops automatically and remains stopped
until another spool is mounted ready to be wound when it is automatically
started.
(e) The spool head is slit.
() The thread is drawn into the slit.
(g) The thread is cut outside the slit and the end thereof connecting with the
bobbin is held to be in readiness for the commencement of the next spool, and
(h). The completed spool is dropped from the spindle.
Betwixt the winding operations the thread guide is moved from the end of the
longest traverse where it must stop to the end of the shortest traverse where
it must start on a new spool by devices hereinafter termed the start fixing
mechanism.
Although in this Specification I shall for convenience. designate the various
mechanisms as above mentioned I do not wish it to be understood as limiting
myself to the exact mechanism, either in number, arrangement, or form of parts
which I shall set forth in more particularly describing the machine.
The best form of machine in which I have thus far embodied my invention
is set forth in the following description and the accompanying drawings, in

hook has reached its original position and has cut the thread from the spool against
a front chisel edge resilient bar and has also gripped the thread from the thread
guide against a rear bar.

Figure 21 is a side view corresponding to that in Figure 20 and shows the ejector
in its forward position having freed the spool from off the spindle and also
conveyed by means of its pin attachment, the thread extended between the hook
grip and thread guide to a position to be caught on the shoulder of the spindle.
Figure 22 is a front view of the parts shown in Figures 20 and 21 and showing

and by a dotted line the position of the thread corresponding to that shown in
Figure 21.
Figure 23 is a transverse vertical section of the parts in their relative position
for receiving a fresh spool.
The main frame consists of two upright parallel plates or bars A and B. From A
projects forward below the spindle bearings, a part C which carries the slides for
many of the parts. From B projects rearwardly a part D which carries the cam
shaft 1 and a spindle turning shaft 151. The parts, A, B, C and D are all secured
to a bed plate E to which is also secured the mounting of the transverse changing
and other mechanisin hereinafter described. This bed plate E' is continuous and
thus unites the bearings of all the mechanisms with absolute firmness. The front
edge of the bed plate E terminates in the same vertical plane with the front of
the part A, so that whilst the bed plate underlies and supports those parts of the
machine lying to the rear of the spindles, the spindles overhang the space in front
of the bed plate and the bed plate thus forms no obstruction to dropping spools
when completed.
'
The spool mounting and dismounting mechanism 2 is a positively revolved spindle.
3 is a spindle in alignment therewith free to revolve. Projections 4 and are
provided on the ends of the spindles adapted to enter the spool hole at opposite
ends, as shown in Fig. 6. A sleeve or spool head abutment 6 surrounds the
spindle 2 and is pressed toward the extremity of the spindle by the spring 7. A
sleeve or spool head abutment 8 surrounds the spindle 3 and is pressed toward the
extremity of the same by the spring 9. Pins 2 and 3 project from the spindles 2
and 3 respectively into slots in the sleeves limiting the extent to which the sleeves
may move the movement of the sleeve 6 being much more limited than the
sleeve 8, as indicated by the lengths of slots shown. The end of the sleeve 6 is
serrated as shown in Figure 23. The set screw 10 forms a back centre bearing
for the spindle 3 and may be employed also to take up wear. The longitudinal

page_text: adjustment of the spindle 3 is capacitated by the clamp 12 as is also its removal.
It is necessary for mounting and dismounting the spool that one of the spindles 2
or 3 should be movable longitudinally to and from the other, and to this end I
mount the bearing or holder 11 of the spindle 3 in a clamp 12 upon a bar 13
extending from end to end of the machine, as shown in Figure and carrying all
of the spindles 3. This bar 13 is mounted upon the bars 14 and 15 at opposite ends
of the machine and the latter bars are guided longitudinally in a horizontal plane
by suitable guideways upon the main frame of the machine. Motion is communi-
cated to the bars 14 and 15 by cams 16 mounted upon opposite ends of the shaft 1,
which are timed to move the spindles 3 to and from the spindle 2 at the proper
instants.
The spools to supply each pair of spindles are held in a hopper 17 extending
vertically at one side of the spindles and open at the bottom and there provided
with the guideways 18 and 19 which are inclined at the angle shown being an angle
of 45 degrees. In these guideways is mounted a hopper bottom consisting of a
plate 20 carrying at its forward end a rebate 21 so constructed that in one position
the plate 20 will close the bottom of the hopper and in another position the rebate 21
will catch any spool falling from the bottom of the hopper, as shown in Figure 5.
The bottom of the rebate is parallel with the guideways. It is necessary now that
means should be provided for reciprocating the hopper bottom so that it may carry
any spool received in its rebate from below the hopper to between the spindles 2
and 3. This mechanism consists in a link 22 pivoted at one end to the hopper
bottom and at the other end to a bar 23 adapted to reciprocate longitudinally in a
horizontal guideway on the main frame of the machine and extending all the way
across the machine so as to carry a link 22 for each hopper bottom. This sliding
bar 23 is moved by a lever 24 actuated by a cam 25 on the shaft I so constructed
as to properly time the motions of the hopper bottom.
It is necessary further to supply an ejector to thrust the spool off from the end
of spindle 2 when spindle 3 recedes. 26 is such an ejector adapted to move parallel
with the axis of the spindle from the position shown in Figures 7 and 19 to the position
shown in Figure 21. This ejector consists simply of a projection adapted to abut
against the head of the spool from the longitudinally sliding bar 27 having suitable
guideways in the frame and pivoted to the end of rock arm 28 mounted upon the rock
shaft 220 which is actuated through the arm 221 and the connecting rod 222 from
a cam 223 on shaft 1. Said cam is constructed so as to properly time the motions
of the ejector.
The cams by which the parts of the mounting and dismounting mechanism are
actuated are timed to produce the following results: When the spindles are in
readiness to receive a new spool, the spindle 3 will be in the receded position shown
in Figure 23 and while it remains so the hopper bottom carrying a spool in its
rebate will be moved from the position shown in Figure 5 diagonally upwards until
the axis of the spool is a trifle below the axial line of the spindles 2 and 3, as shown
in Figure 23. While the hopper bottom holds the spool in this position, the
spindle 3 is advanced, its projection 5 enters the spool hole and forces the spool
longitudinally toward the spindle 2 until the projection 4 enters the spool hole at
the opposite end and the spool head is clasped between the spring pressed sleeve 8
and the serrated face of the spring pressed sleeve 6. The conical form of the
projections 4 and 5 will serve to centre the spool with the axial line of the spindles 2
and 3 and thus slightly raise the spool off of the hopper bottom which is then
retracted to its first position shown in Figure 5. Then a new spool drops into its
rebate and it so remains until the spool just mounted is completed. After the
winding of the mounted spool is complete and the end of the thread has been secured
and cut the spindle 3 is receded from the spindle 2 and the ejector coming forward
pushes the spool off of the projection 4 and the spool drops into a suitable receptacle
below, through the opening between the bar 13 and the traversing bar 61 over
which opening the spindles project transversely.

page_text: The pressure of the sleeve 8 should be less during the winding operation than it
is when the spool is being mounted and than it is when the spool is being slit.
When the spool is being mounted the pressure must be so great as to press the
teeth of the sleeve or arbor 6 firmly against the head of the spool; and again when
the knife comes forward to slit the spool head so that the pressure of the knife will
be fully opposed by the presence
cleeve U. But when the thread being
wound to prevent the heating and wearing of the spindles, it is desirable that the
pressure of the sleeve 8 should be lessened. All of these three conditions are
accomplished by the form of the cam 16, which as shown in Figure 2 is slightly
flattened at and near its centre (between the points 224 and 225) so as to allow
the bar 13 a slight retreat under the combined pressures of the springs 9.

wound to prevent the heating and wearing of the spindles, it is desirable that the
pressure of the sleeve 8 should be lessened. All of these three conditions are
accomplished by the form of the cam 16, which as shown in Figure 24 is slightly
flattened at and near its centre (between the points 224 and 225) so as to allow
the bar 13 a slight retreat under the combined pressures of the springs 9.
THE SPOOL SLITTING MECHANISM.
As soon as the thread winding mechanism has completed its function and stopped,
it is necessary that one flange of the spool should receive the customary slit, which
I accomplish by means of a knife 29 located in the plane of a chord of the
periphery of the spool flange as shown in Figure 5 and extending so as to intersect
the periphery sufficiently to make the depth of slit required. This knife projects
in a horizontal plane from the bead 30 being held in a horizontal slot therein. The
head is as clearly shown in Figure 7 mounted upon the end of a longitudinally
sliding rod 31 provided with suitable guideways in the frame and connected by a
link 32 to an arm 330 connected with a rock shaft 340 which receives motion
through the downwardly extending arm 350 and the connecting rod 56 from the
cam 57 on shaft 1. The arm 330 is connected with the shaft 340 by being pivoted
to an intermediate arm 58 fast on rock shaft 340 and held from vibrating by the
set screws 59. By these set screws the adjustment is made to take up the wear
of the knife. The knife is also made adjustable in the slot on the head 30 to
accommodate different sizes of spool heads. The point of the knife is beveled so
as to cut the spool flange to the angle at which the thread will be pulled into the
slot. 57 is a double throw cam so timed that when the winding is completed the
knife advances and makes its cut to the full depth, then recedes about inch or
just far enough to allow the thread to get into the slit while still acting to guide
the thread in, then recedes again after the thread is in the slit to its normal
position. The form of this cam is illustrated in Figure 7. The slot in which
the knife is held being parallel with the guideways of the knife bar, the knife will
always be held in its plane of movement and require no adjustment to make it cut
in a uniform direction.
THE THREAD SECURING MECHANISM.
As soon as the spool flange has been slit by the knife before described and after
such knife has been partially but not wholly, retracted from the slit, it is necessary
that the thread between the thread guide and the spool should be inserted and
forced into the slit so as to be held therein. To this end I provide an oscillating
finger 33 the normal position of which is shown in Figure 7, and the subsequent
positions of which are shown in Figures 16 to 19. This finger is of the form
shown, being provided with a hook on the end. It is mounted upon a rock shaft 34
to which a rocking motion is communicated from the cam 35 on the shaft 1 through
the lever 36 connecting rod 37 and the crank 38. This crank is so timed as to
give the finger the following motions. The finger 33 rocks downward when the
knife has slit the spool flange and partially retreated from the slit. In its descent
the finger catches the thread extending from the thread guide to that end of the
spool barrel next the slitting flange (the stop motion having stopped the thread
winding at the end of the spool barrel). The finger swings above the knife 29 to
a position slightly below the plane of the upper surface thereof, as shown in
Figure 17 so as to lay the thread on the flat upper surface of the knife and in

page_text: While
position to be seized by the hook 39, which draws the thread taut across the
periphery of the spool flange while the knife surface guides it into the slit.
the finger 33 holds the thread in the position shown in Figure 17 the thread
holding mechanism which I will next describe and of which hook 39 is a member,
advances and relieves the finger of the thread and the finger returns to its normal
position shown in Figure 23 and remains there until another spool has been wound
and slit. By having the finger oscillate instead of reciprocate, I am enabled
to carry the thread down far enough for the hook 39 to grasp it with absolute
certainty.
THE THREAD CUTTING AND HOLDING MECHANISM.
As soon as the thread has been secured in the spool slit, it is necessary that it
should be cut between the spool and the thread guide and that the end thus formed
next the thread guide should be held in proper position to enable the winding of
a new spool to be started automatically. To this end I provide a reciprocating
hook 39 the path of which is just outside the are traversed by the finger at a
point above the lowermost position of the finger, so that while the finger is down
the thread between the flange and the thread guide will be drawn down into
position to be caught by the holding hook 39, as shown in Figure 16.
The holding
hook 39 is mounted upon a slide 40 adapted to reciprocate in horizontal guideways
in the main frame. This slide 40 carries the holding hooks for all the spindles
and is reciprocated by a lever 41 actuated by a cam 42 on the shaft 1. In receding
after having grasped the thread the holding hook 39 retreats between two cheek
plates 43 and 44 which exert a spring pressure against the sides of the hook 39
and one of which, 43, is longer than the other, 44. The thread will first be clamped
between the plate 43 and the side of the hook 39 and as the hook retreats further
the thread, while still clamped and held on that side of the hook will on the other
side of 'the hook be brought against the chisel edge of the plate 44 and thereby
cut. Thus the spooled thread is cut loose from the thread yet on the bobbin
and the end of the unspooled thread is held between the hook 39 and the cheek
plate 43 as shown in Figure 20.
It is still necessary that the end of the unspooled thread be brought into such
position as to be held by a newly mounted spool and to turn therewith. To this
end I provide upon the ejector 26 a pin 45 projecting downward so that the
thread extended between the thread guide and the check plate 43 will lie in the
path of this pin as the pin is carried forward by the ejector. The pin therefore
catches the thread and carries it beyond the serrated end of the sleeve 6 so that
when the pin retreats the thread will lie across the serrated end of the sleeve 6, as
shown in dotted lines in Figure 22. Now obviously, as soon as a new spool is
mounted the end of the thread coming from the thread guide will be clamped
between the spool head and serrated end of sleeve 6. By mechanism hereafter
described the thread guide at the commencement of the winding of a new spool
will be opposite the junction between the flange and barrel of the spool. Therefore.
the thread will extend from where it is held between the spool head and the end
of sleeve 6 over the flange of the spool to the thread guide, and as soon as the
spool commences to turn will be wound upon the barrel thereof, leaving a
projecting end extending out from the barrel and over the spool head. To cut off
this end which is called the "scrap end" is the object of the mechanism which I
will next describe.
THE SCRAP AND CUTTING MECHANISM.
46 is a knife mounted upon an arm 47 pivoted to the frame at 48 and rocked by
the reciprocation of a slide 49 from which motion is communicated to the arm 47
through the pin 50 and the arm 51. The slide 49 (which has the same connection
with a knife 46 for each spindle) is connected with a lever 52 by a bolt 53 and
link 230. Oscillating motion given this lever through a rod 231 and a pin 232

page_text: from a cam 233 on the shaft 147 in antagonism to which cam the spring 234 acts.
The knife 46 is made adjustable on the arm 47 by means of the set screw 54 and
vibrates between a position where its edge is in contact with the flange of the
spool, as indicated in dotted lines Figure 7, and the position shown in full lines in
Figure 7. The parts from which this knife receives its motion are so timed that
the edge of the knife is pressed against the flange of each spool immediately after
the winding of the spool has commenced. This cuts off the end of thread which
passed from the barrel of the spool over the flange to the holding cheek piece 43
and as soon as the hook 39 again advances the cheek piece loosens its hold upon
the end of thread and it drops into any suitable receptacle below. Having
accomplished this function, the knife 46 raises again in time to be out of the way
of the thread being wound upon the spool. It is insured, that the scrap ends will
not clog the machine because the hook 39 moves horizontally and ea:h time it
advances it pushes out from behind the cheek piece the scrap end which it drew in
when it previously retreated.
55 is the thread guide which is constructed and mounted on the same principle
as described in United States Letters Patent granted to me No. 413447 dated
October 22nd 1889.
The thread guide and the parts connected with the same are mounted upon a
standard 60 which is fixed upon a laterally reciprocating frame 61 vibrated by
longitudinally reciprocating bolts 62 and 63 having guideways in boxes 64 mounted
upon the main frame. These bolts connect the frame 61 with a yoke 65 from
the middle of which yoke projects rearwardly the rod 66 mounted in bearings
enabling it to reciprocate longitudinally and bearing a carriage 67 which is fixed
upon the rod 66 by the set screw shown in dotted lines in Figure 12. The
carriage 67 bears a screw threaded nut 68 bolted to the carriage within which nut
turns a shaft 69 having an external screw thread at 70 which engages with the
screw thread of the nut 68. The shaft 69 is mounted in suitable bearings by which
it is fixed longitudinally and it carries upon one end the beveled gear wheel 71
which meshes with the beveled gear wheels 72 and 73 which turn freely upon the
shaft 74 excepting as motion may be communicated alternately to one or the other
of the gears 72 and 73 by the clutch 75 splined to the shaft 74 between them.
The shaft 74, while the winding.is in progress is continually revolved through the
line of gears 76, 77, 78, 79 and 80, the pulley 81 the belt 82, pulley 83, the
shaft 84, the pulley 85 fast upon it, the belt 86 and the pulley 87 which is driven
by the engine.
88 is an arm by which the clutch 75 is shifted alternately into engagement with
the beveled gear wheels 72 and 73, and which arm is mounted upon a longitudinally
reciprocating rod 89, the end of which is pivotally connected with a rocking arm 90
fixed upon a vertical shaft 93 upon which vertical shaft 93 is fixed a finger or dog
head 94. The point of this dog head is V-shaped and engages with a V-shaped
projection 95 on an arm 96 pivoted at 97 to the slides 98 and pressed against the
dog head 94 by the springs 99 and 100. The slide 98 is free to slide backward
and forward in the direction of the arrow 101 Figure 10 and carries the fingers 102
and 103 which are adjusted to slide to and from each other and which together
constitute a shaper; the angular divergence of and distance between their adjacent
sides timing the changes of traverse.
The carriage 67 also bears an arm 104 which contains a slot 105 engaging with
a stud 106 on the carriage 107. This carriage is mounted so as to be free to
reciprocate in the direction of the arrow 101 Figure 10 upon a table 302 provided
with a slot for that purpose. The table 302 is carried by friction rollers 108 and
109 so as to reciprocate in the direction of the arrow 110 Figure 12. Connected with
one side of this table is a rod 111 mounted in bearings enabling it to reciprocate
with the table and to the end of this rod is connected the cord 112 carrying the

page_text: weight 113 which exerts a constant pull on the rod and on the table connected
therewith. Upon the carriage 107 is mounted a stud 114 which extends upwardly
between the fingers 102 and 103 of the shaper.
Now the operation of the thread winding mechanism may be described as follows.
It is apparent that the thread guide is compelled to move in unison with the
yoke 65 and that this yoke must be moved backward and forward in the direction
of the arrow 115 Figure 8 and that its length of traverse must be increased at
every change of traverse in order to accommodate the flare of the spool heads and
it is to convert the rotation of the pulley 87 into the traversing motions of the
yoke 65 and its connected rod 66 that is the object of the mechanism which has
just been described.
The continuous rotation of the pulley 87 is conveyed through the train of belts,
pulleys and gears already referred to, to the shaft 74 which is continuously rotated.
The continuous rotation of the shaft 74 is communicated to the shaft 69 so as to turn
the shaft 69 alternately in opposite directions depending upon whether the clutch 75
engages with the beveled gear 72 or the beveled gear 73. When the shaft 69 revolves
one way the carriage 67 will traverse in one direction, and when the shaft revolves
the other way the carriage will traverse in the other direction. Therefore it only
remains to provide automatic means for shifting the clutch 75 in order to produce the
requisite changes of traverse. The operation of this automatic mechanism is as
follows.
The stud 114 being connected with the stud 106 is compelled to traverse back-
ward and forward with the carriage 67. As it traverses forward it will strike the
finger 102 and, as it traverses backward, the finger 103, of the shaper. When it
strikes finger 102 it will shove that finger and the slide 98 and the arm 96 forward
with it, and the reverse operation takes place when it strikes finger 103. In
Figure 10 the V-shaped projection on the arm 96 and the doghead 94 are shown
in the position they occupy when the traverse is backward or toward the finger 103.
When now the stud 114 strikes the finger 103 and thereby shoves the arm 96
backward, the first effect will be for the incline of 95 to slide up on the incline
of 94 until it has passed the apex thereof whereupon the springs 99 and 100 will
press the opposite incline of 95 against the opposite incline of 94 so as to swing 94
back to the opposite end of its stroke. As however, the finger 94 is swung it will
shift the clutch 75 from engagement with one gear wheel to engagement with the
other where it will remain until the stud 114 has moved into contact with and
shoved the finger 102. When this occurs, the V-shaped projection 95 will be on
the opposite side of the dog head 94 and as it is carried backward it will swing the
dog head 94 back into the position shown in Figure 10 thereby again shifting the
clutch and placing the parts in position for producing the next change of traverse.
Thus when the stud 114 shoves either member of the shaper, the dog head 94 is
tripped backward or forward and the clutch 75 is shifted so as to produce the
change of traverse.
But it is necessary also that each traverse should be made longer than the
preceding one and it is evident that this may be accomplished by moving the
stud 114 so that it constantly advances toward the extremity of the shaper and
thus, owing to the flaring sides of the shaper, has constantly a longer distance to
travel before it commences to push either of the fingers thereof. The tendency
of the weight 113 is obviously to pull the carriage 107 bearing the stud 114 in
the direction of the arrow 110, but the carriage is drawn in the opposite direction
in antagonism to the weight by a yoke 116, fixed at one end upon the rod 111,
and mounted at its opposite end in a horizontal guideway 117 and provided with
a laterally projecting pin 118, which rests against a crown cam 119.
To this cam
is fixed a ratchet wheel 120 actuated by the pawls 121 and 122 each of which is
pivoted to the opposite extremity of a rocker 123, centrally fixed upon a shaft 300
having its bearings in a standard 124 on the frame. Upon the opposite end of
this shaft is fixed the oscillating arm 125, the extent of oscillation of which in both
directions is limited by the adjustably fixed set screws 126 and 127, 128 is a rod

page_text: pivoted to the arm 125 and connected by the stud 129 with a disc 130 clamped
face to face with a disc 131 by a central bolt 132. A circular recess 133 is
turned in the face of the disc 131 which is filled with an annulus 134 of leather or
other material suitable for a friction surface, also with an annulus 135 of suitable
metal to form frictional, contact with the leather. The latter annulus is held from
rotating on the disc 130 by a pin 136, and three or more set screws as 137 and 138
are provided for setting the annulus 135 up against the annulus 134, thus forming
substantially a frictional clutch. The disc 131 is fixed to the yoke 65 and as this
yoke reciprocates in the direction of the arrow 115 the clutch compels the rod 128
to reciprocate with it in both directions until on the forward traverse the arm 125
strikes against the set screw 126 and until on backward traverse the arm 125 strikes
against the set screw 127. As soon as this arın strikes against either set screw the
friction between the discs 130 and 131 will yield and the movement of the rod 128
will stop until the traverse changes. The set screws 126 and 127 will be adjusted
so that each of the pawls 121 and 122 will be moved exactly the distance for it to
engage a new tooth of the ratchet wheel 120. In factory parlance the ratchet
wheel 120 is called the "
row cam because it controls the number of rows of
thread wound on the spool, two rows or layers being wound for each tooth.
Therefore this row cam is changed as the machine is required to wind different
numbers of rows and for each change of the row cam the set screws 126 and 127
must be adjusted correspondingly.
"
In the automatic machines heretofore used the thread guide was lifted only
once for every two rows of thread. Therefore, the extent to which it was lifted
was made the mesne between that required for each row and one row would be
wound loose because of too little pressure and the next tight because of too much
pressure. In my machine on the contrary it will be observed that the row cam
and its co-operating mechanism causes the thread guide to be receded at the
commencement of each row. This not only benefits the quality of the work
done but increases the speed of the machine because the equality of pressure
diminishes the tendency to burn or break the thread when running at a high
speed.
Now it will be evident that on the forward traverse of the yoke 65 the pawl 122
will rotate the ratchet wheel 120 and that on the backward traverse the pawl 121
will rotate the ratchet wheel 120; therefore, the ratchet wheel 120 will move
intermittently on each traverse and likewise the cam 119. This produces a
corresponding motion in the yoke 116, the rod 111, the carriage 107 and the
stud 114 in antagonism to the weight 113, and thus intermittently the stud 114 is
on each traverse, moved nearer to the extremity of the shaper and thereby given
a longer distance to travel on each succeeding, traverse than on the preceding one
before giving the shove to the shaper which is necessary for changing the traverse.
The shaft of gear 79 is mounted in a slot concentric with gear 78 so that it admits
of different sized gear 80 being used for different sized thread without altering the
distance between the centres of the belt 82. Also the pulleys 81 and 83 are made
conical so as to take up the pitch of the fraction of a tooth if the size of thread
requires it.
I have now described the parts and the operations necessary for imparting to
the yoke 65 the traverses which grow successively longer from the commencement
of the spool to its finish, which traverses are communicated to the bar 61, carrying
all the thread guides. It is further necessary to manipulate the thread guides so
that each of them automatically retreats from the barrel of the spool as the thread
accumulates thereon until the last two (more or less) traverses are reached, when
it is necessary that the thread guide should press against the thread with sufficient
force to give it the external smooth appearance necessary for a marketable article.
For thus manipulating the thread guide the following means are provided. The
standards 60 for the thread guide instead of being fixed directly upon the bar 61
are fixed upon slides 139 and 140 having suitable longitudinal guideways in the
bar 61. These slides are urged in the direction of the arrow Figure 3 by a

page_text: weighted lever 141 acting through the cord 142 so that when the pull of this cord
upon the slides 139 and 140 is unopposed, the full pressure derived from the
weighted lever will be distributed among the thread guides and delivered by
them on the spools. To shove the slides 139 and 140 in antagonism to tho
weighted lever 141 during all the traverses except the last two (more or less)
a scroll cam 143 is arranged to operate upon a roller 235 mounted on the
slide 140.
This scroll cam 143 is fixed upon a shaft 147 which receives motion through
the beveled gears 148 and 149 from the shaft 150, being the same shaft upon
which are fixed the intermittently moving ratchet wheel 120 and cam 119.
Therefore, the scroll cam 143 will be moved intermittently on each traverse and
it is so constructed that for each movement it causes the thread guide to retreat
the thickness of a layer of thread on each traverse until the last two (more or
less) when the roller 235 will fall off the point of the cam and the subsequent
retreat of the thread guide will be due to the accumulation of thread which will
bear the pressure of the weighted lever 141. Obviously, the scroll cam 143 will
be changed for different sizes of thread.
The thread guide is adjustably secured by a set screw 236 and slot to a
support 237 pivoted to the stud 60 so that the operator may at any time throw
it back into the position shown at the left of Figure 5. It is held either thrown
back or thrown forward by a latch 238 engaging with a stud 301 on the tail of
the support 237, bat when winding it occupies the forward position shown at the
right of Figure 5.
Each of the spindles 2 is rotated from the shaft 151 through the beveled
gears 152 and 153 and the shaft 151 is driven by the beveled gears 154 and 155
From the shaft 84 upon which the pulley 85 is fixed. Each spindle has a bearing
in the two branches A and B of the main frame. To take the thrust of mounting
the spools, I provide in front of the back bushing 277 a friction washer 278, in
front of which are placed the lock nuts 279 and 280.
While the thread winding is in progress the thread guide support 60 is forward
as shown at the right of Figure 5 but as soon as the winding is finished it is
necessary for this support to be moved backward automatically so that the thread
guide will be out of the way of the other operations. This is accomplished by a
cam 212 on shaft 1 which connects with slide 139, 140 by a lever 213 pivoted to the
stud 214. While the winding is in progress and the cam 212 is stationary this lever
rests in a notch in the cam, as shown in Figure 1, but while the shaft 1
revolves the lever is raised out of this notch and the thread guides are thus shoved
back as required.
STOPPING AND STARTING MOTIONS.
The object of the stop motion is to shift the belt 86 from the pulley 85, fast on
the shaft 84 to the loose pulley 157, which is fast upon the sleeve 172, carrying the
worm 164, at the same time to apply a brake-strap 158 to the pulley 159 which is
connected to the pulley 85.
As the pulley 85 turns, the shaft 84 on which it is fixed at the same time drives
the spindle turning shaft 151, and the belt 82 by which the traverse actuating and
changing mechanism is run. As the pulley 157 turns the sleeve 172 to which it is
fixed through the worm 164 and the worm gear 165 drives the shaft 1 from which
are taken the motions which are in operation while the winding is suspended and
which shaft I makes a complete revolution each time the winding is suspended.
160 is the belt shifter which is constantly urged in the direction of the arrow 161
by the weight 162 acting through the cord 163. The belt shifter 160 slides upon
a bar 167 and this bar in turn slides in guideways on the frame. A pin 168 from
the bar 167 projects into a slot in the belt shifter 160, as shown in Figure 8. The
bar 167 is constantly urged in the direction of the arrow 169 by the weighted
lever 170 and the weight 171 on this lever is sufficient to overbalance the
weight 162 and move the sliding bar 167 and the belt shifter 167 from the position
1

page_text: 9
shown in Figure 8 to that shown in Figure 13. While the operation of winding
is in progress a hook 174 engages with a notch in the sliding bar 167 and prevents
it from yielding to the weighted lever 170. It will be remembered however that
the shaft 150 moves during the winding operation intermittently once during each
traverse and that it makes one complete revolution for cach complete winding
operation. This motion is imparted to an arm 175 fixed upon it and carrying,
adjustably secured in a slot the pin 176. 177 is a lever resting normally in the
position shown in Figure 8, upon a stud 178 which it carries, but having an adjust-
able point 179 at its opposite extremity which projects into the path of the pin 176,
so that the lever 177 is tripped into the position shown in Figure 13, once for each
rotation of the shaft 150. On the top of the lever 177 rests a pin 180, sliding
freely in a stock 181 which is pivoted at 182 and provided with a laterally and
upwardly projecting arm 183. This pin 180 extends entirely through the stock 181
and is forced upward so as to project further above the stock, as shown in Figure 13,
by the lever 177 as the latter raises. When the pin 180 is in its lowermost position,
it is not within the path of the movement of the rod 184 but when it is in the
raised position it projects within the path of the movement of that rod. The
rod 184 is mounted at one end with capacity for longitudinal adjustment upon
the traversing yoke 65 and projects through suitable guideways toward the top of
the pin 180 when in its highest position. When, therefore, the pin 180 is raised, the
next backward traverse of the yoke 65 will cause the rod 184 to shove the
pin 180 over into the inclined position shown in Figure 13 so as to raise the arm 183
and the arm 144 resting on it by which the hook 174 which is connected with the
arm 144 is tripped out of the notch in the slide 167 and the slide shoots from the
position shown in Figure 8 to that shown in Figure 13 dragging the belt shifter
with it so as to shift the belt from pulley 85 to pulley 157 and permit the nose of
the lever 185 to fall behind the projection 186 on the belt shifter and hold the
belt shifter in that position against the impulse of the weight 162 even after
the slide 167 has been returned to the position shown in Figure 8 which is
accomplished as follows.
On the shaft 1 is a collar carrying the projection 187. A lever 188 pivoted
at 189 is arranged so that one arm in one position comes within the path of the
projection 187. The other arm of the lever 188 is pivotally connected by a
link 190 with one arm of the lever 191 pivoted at 192 and carrying upon its
opposite arm the friction reller 193, which bears against the side of the upper arm
of lever 170. Now, as the projection 187 is carried around by rotation of shaft 1
it will strike lever 188 and thrust it from the position shown in Figure 13 to that
shown in Figure 8, compelling the slide 167 to return to the position shown in
Figure 8 where it is seized and held by the hook 174. 194 is a projection upon
the shaft 1 adapted to strike the lower arm of the lever 185 as the shaft
rotates;
and after the shaft has revolved so that the projection 187 has thrust the slide 167
into the position shown in Figure 8 the further rotation of the shaft soon brings the
projection 194 under the tail of the lever 185 so as to lift the nose of that lever
from behind the projection on the belt shifter and permit the belt shifter to be
pulled by the weight 162 back into the position shown in Figure 8.
To the rear end of the slide 167 is fixed a bracket 195 and this in turn carries a
wedge 196. This wedge projects through a slot in the bolt 197 connected with one
end of the brake band 158. When the slide 167 moves forward in the direction of
arrow 169 it advances the wedge 196 in its slot and brings the brake band 158
down upon the pulley 159 and stops the shaft 84 and all the thread winding and
traverse changing mechanism connected with it. The brake band is loosened by
the retreat of the wedge with the backward movement of the slide 167.
198 is a friction block fixed with capacity for back and forth adjustment upon a
bracket 199 fixed upon the belt shifter 160. This friction block 198 is beveled
and provided with a co-operating beveled friction surface at the edge of the flange
of the pulley 157 so that when the belt shifter is in position to throw the belt on
pulley 85, the friction block 198 will act as a brake on the pulley 157 and stop

page_text: block will be out of contact with the latter puney. A non-a
is also provided which consists of the belt shifter 209 operated by the hand
lever 210 through the rock shaft 211.
START FIXING MECHANISM:
When the spool has been wound it leaves the thread guides in line with the
periphery of the spool head or in other words, at the end of the longest traverse.
When new spools are inserted and the winding recommences the thread guide
must be in line with the barrel of the spool, or in other words, within the bounds
of the shortest traverse and the mechanism about to be described is for moving
the thread guide intermediate the winding operations from the end of the longest
traverse to within the bounds of the shortest traverse.
The shaft 1 is connected by the gears 200 and 201 with the shaft 202 carrying
the eccentric connecting rod 203 which oscillates the arm 204 fixed on the
shaft 205. 206 is another arm fixed on the shaft 205 and oscillating therewith
and to which is pivoted a pawl 207 engaging with ratchet wheel 208 fixed to the
beveled gear wheel 72. Now, through the chain of mechanism just described, the
beveled gear 72 will be rotated as the shaft 1 makes it revolution so as to move
the thread guides upon their backward traverse the proper distance for the
purpose above set forth.
In practical operation, however, something more is necessary because the practice
is to stop the winding just short of the end of the spool and therefore just before
the dog head 94 has passed over the V-shaped projection 95 which it is necessary
that it should pass over for the start fixing mechanism to properly perform its
function. To cause this result, I provide on the shaft 1, a projection 275, which as
the shaft revolves, will strike a projection 276, on the slide 98 and kick that slide
over far enough to throw the dog head 94 on the opposite side of the V-shaped
projection 95 to that shown in Figure 10.
In practice the winding will stop before the pin 118 has passed over the highest
point of cam 119 and it is necessary that this cam should be moved enough for that
purpose while the winding is suspended so as to allow the stud 114 to move back
into position for the short traverse of the next winding operation. To this end I
provide on the shaft 1 an eccentric pawl 281 engaging with the ratchet wheel 282
on shaft 150. Each revolution of shaft 1 will cause the pawl to turn the ratchet
wheel and consequently cam 119 just far enough for the purpose indicated.
Among the many features of my machine may be mentioned the following:
The spindles run transversely of the machine and the length of space occupied by
them is less than five and a half feet; the total length of the machine being only
six feet. By confining the spindles within this space, the girl standing in the
centre may reach all the spindles without walking. The shaft 69 being arranged
below the shaft 84, one does not project materially further backward than the other
and the depth of the machine is thus limited. The spindles are securely journaled
and can be removed with great convenience. The spools are held over an open
space through which they are dropped. The spindle driving gears are entirely out
of the way at the back of the machine. The thread guides are so located that the
spools are open to inspection from above at all steps of the winding. The non-
reciprocating spindles project side by side from the front of a stationary frame in
which their bearings may be prolonged to any extent. The reciprocating spindles
project inversely from the front bar of a three sided frame the two end bars of which
slide on the stationary frame and connect with the cams at their extremities. The
thread guides are mounted on the front bar of substantially a square frame the two
end bars of which slide on the stationary frame and the rear bar or yoke of which at
its middle is connected with the traversing nut which is continuously in gear with

page_text: the screw threaded shaft, which shaft reverses to reciprocate the nut. The
mechanisms for driving the spindles are arranged at the back of the main frame
where sufficient compass is to be had for distributing them and embodying them in
cams arranged upon a single shaft so as to increase their accessibility simplicity and
positiveness of action and enable a person setting the cams to glance along the line
and time them with great ease and accuracy. The thread guide retreats in a right
line; the same surface of contact with the thread is preserved throughout the whole
winding and, when in position to operate, the motions of the guides heing controlled
by rectangular slides, the guides and guide holders may be mounted on planed
surfaces which insure their always coming to the proper adjustment when removed
and replaced. The thread guide retreats at the beginning of each row or layer of
thread and equality of pressure is therefore preserved. The same belt drives all
the mechanisms. The slit is cut on the bottom of the spool and the holding hook
works horizontally so that after the scrap end is cut off the next forward motion of
the hook will allow the scrap end to drop down without clogging. The thread is
introduced across the spool abutment of the non-reciprocating spindle without any
reciprocating movement of that abutment. The machine is stopped by the thrust
of a rod adjustably fixed on the traversing frame enabling the stop motion to be
accurately brought into play at any point of the traverse, preferably just a trifle
before the end of the last row is reached to have the thread go properly into the
slit. A continuous bed plate underlies and connects the supports of all the bearings.
The thread guides are brought to the end of the shortest traverse when the spindles
are not turning. The hoppers are arranged upright between the spindles. The
spool is conveyed from the hopper to the spindles in an upwardly inclined direction
so as to offer no obstruction either above or below the spindle and enable the spool
to be retained in an angle of the carrier without being secured and admit of the
direct retreat of the carrier. Experience has demonstrated that the implements for
handling the thread and spools and the mechanism for stopping and starting are so
accurate positive and certain that the number of defective spools and mechanical
attention or repairs necessary are reduced to a minimum even when the speed is
unprecedentedly high.
