COMPLETE SPECIFICATION filed by the said William Robert Lake at the
Office of the Commissioners of Patents on the 10th January 1883.
WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN SPOOLING MACHINES, PARTS
OF WHICH IMPROVEMENTS ARE APPLICABLE TO OTHER MACHINES," Communicated
to me from abroad by Nathan Adolphus Baldwin, of Milford, Connecticut,
United States of America,
This invention relates chiefly to improvements in machines for winding thread
upon spools, commonly called "Spooling machines." The said invention is particularly
adapted to winding spools or bobbins for sewing-machine shuttles, but is also
applicable to winding other spools, and parts of the said improvements are applicablo
to machines employed for other purposes, The chief object of the said invention is
the construction of a simple and automatic machine which will regularly and evenly
lay the thread upon the spool in a positive and predetermined quantity, and the
said invention comprises the construction of the machine, and the combination of
parts as hereinafter described.
In the accompanying drawings

Figure 1 represents the spool.

page_text: A is the bed-plate on which the mechanism is arranged; B is the driven mandrel
arranged in suitable bearings B, and so as to revolvo freely therein; and B' is the
pulley through which rotation is imparted to the mandrel by the application of
power thereto through a band running on the said pulley, in the usual manner. In
nxial line with the mandrel B is an adjustable spindle C, arranged in a bearing C',
and constructed to centre one end of the spool D while the other is engaged in the
mandrel B, and so that the rotation of the mandrel B will be imparted to the spool D.
The spindle C, is made adjustable by a spring pressure, as seen in Figure 1 in
broken lines, for the introduction or removal of the spool; the spool in this case is
constructed, as seen in Figure 1º, with a central projection a, at each end to enter a
corresponding centre in the mandrel and spindle, so as to ensure the proper centring
of the spool. E, is a leading-screw formed on a shaft El, arranged parallel to the
axis of the mandre! B and spindle C, and supported in suitable bearings, preferably
on centres, as seen in Figure 5. The leading-screw E moves the guide for carrying
the thread as hereinafter describod, for this purpose it is necessary to impart to the
leading-screw a rotation in one direction while the guido is travelling from one end
of the spool, and in the reverse direction when the guide is returning; to impart
this rotation to the leading-screw I arrange two pulleys FF either on the shaft, or
so as to revolve concentric with it, and preferably grooved, and in such relation to
the pulley B³ that the same band which drives the pulley B' shall drive the two
pulleys F, F, that is to say, one run of the belt passes, say, over the top of the
pulley F down around the pulley B, up and over the other pulley F¹ or so that the
two runs of the belt come upon the same side of the two pulleys F and F¹, as
indicated in broken lines in Figure 2, thus one pulley F, will be driven in one
direction as indicated by the arrow Figure 1, and the other pulley F', in the opposite
direction is also indicated by an arrow. On the shaft between these two pulleys
is a clutch-disc G, as seen in Figure 5, which disc is attached to, or forms a part of,
a sleeve G³, on the shaft E', and so as to be moved within the recess in the two
pulleys to engage with either one or the other of the pulleys, the face of the disc
being constructed with recesses to engage with corresponding projections on the
respective pulleys so as to engage with one or the other according to which it is
brought in connection with. It may be either a disc or any suitable clutch-
device whereby either of the pulleys may be engaged with the sleeve G¹. The
sleeve G¹, is keyed to the shaft E', in the usual manner, so that the shaft will revolve
with the sleeve, hence the rotation of the shaft E', will be in one direction when
engaged with one pulley, and in the opposite direction when engaged with the
other.
On the leading-screw is a nut H, which is guided so as to be moved by the screw
in one direction when the screw rotates one way, and in the opposite direction when
.the rotation of the screw is reversed
Between the leading-screw and the spool is a shaft L, on which a sleeve L' is
arranged to move longitudinally, and the said sleeve is prevented from rotating on
the said shaft by a key b, or otherwise, this sleeve L', carries an arm L³, which
extends forward over the spool, as seen in Figures 1, 2 and 6, and on the reverse
side the sleeve is constructed with a segment-shaped arm L³ which extends into a
slot in the nut H as scen in Figures 1 and 6, so that as the nut traverses the leading-
screw, it moves the arm L³, accordingly.
The thread to be wound is brought to the machine through a tension device M,
thence it is lead through an eye d, in the arm L2, to the spool to which it is made
fast, the rotation of the spool will draw the thread through the arm onto the spool.
The thread of the leading-screw corresponds to the thread to be wound upon the
spool, so that the revolution of the leading-screw will cause the arm L³, to travel
over the surface of the spool as fast as the thread is laid thereon. This arm rides
upon the thread, as it lays it upon the spool, with a spring pressure; this spring
pressure is produced by means of a spring L, bearing upon the arm L³, on the
shaft L, as seen in Figure 7, so that while it operates the arm upon the thread being
laid, it will permit tho arm to rise after ouo layer has been wound upon the spool

page_text: to wind the second layer, and so on until the spool is full, or the requisite quantity,
is wound thereon.
To operate the clutch to reverse the direction of the leading-screw at the
termination of each layer of thread, a fork P, (see Figure 6,) is arranged in a
groove e, in the sleeve C, the said fork is pivotted in a lever P', (see Figures 3
and 4,) and the said lever is connected with a horizontal slide-bar P, from which
adjustable arms P³, P', extend downward.
Below the leading-screw is a shaft R, on which a double sided cam R¹, is arranged
free for longitudinal movement; this cam is grooved on its periphery, and from the,
nut a flange or lug f. extends into the groove, as seen in Figures 4, 5, and 6, so that
this cam traverses its shaft with the nut and between the two stops P³, P', so that
as it strikes the said stops it will move the bar P accordingly, that is to say,
moving toward the stop P³, it will move the bar in one direction, and toward the
stop P', will move the bar in the opposite direction.
The stops being set relatively to the cam R', so that as the thread-guide arm L',
approaches one end of the spool, say toward the arm P³, it will force that arm from
the position seen in Figure 4, to the position seen in Figure 3, which will corre-
spondingly move the bar P, and with it the clutch, which will throw the clutch
from the pulley F, into the pulley F', and reverse the leading-screw, and thereby
cause the nut to move in the opposite direction and carry with it the cam R' until
it strikes the stop P', when it will move the bar P, in the opposite direction, and
correspondingly move the clutch from the pulley F', into engagement with the
pulley F, and so continuing will reverse the leading-screw at each end of the
spool.
r
In order to give to the clutch a movement to throw it into one pulley after it has
been moved from the other, I construct the bar P2, with two inclines h,, which work
over a stud k, on the frame of the machine; these inclines are at one end, the other
end being pivotted to the lever P', so as to perinit the vibration of the lever as it
passes over the said stud. At the pivot 1, between the lever P1, and the bar P, a slight
independent motion is permitted by a slot m, in the bar. A spring T, is arranged
with its end turned down to form a shoulder against which the lever Pl, will stand
in one direction as seen in Figure 4, and while the bar is at the extreme position
to the right. When the bar is moved, as above described, first to the left tho
incline, rides upon the stud k, bringing the angle of the incline upon the stud, as
seen in broken lines, before the bar will have come to a bearing upon the lever P'.
So soon as the angle of the two inclines has passed the centre of the stud, a
spring T, acts upon the bar, tending to draw it downward, and cause the other
incline, to ride down the stud and throw the bar to the extreme left, as seen in
Figure 3.
As the bar rises over the stud k, a tripping device n. on the bar P³, strikes tho
spring T, and raises it from engagement with the lever P¹, so as to permit the action
of the spring on the bar 12, to force the lever P, over to the left, as seen in Figure 3,
and as the bur drops on the other incline the tripping device n, falls and permits
the end of the spring T, to drop upon the opposite side of the lever Pl, as seen in
Figure 3. The throw of the bar P, by the action of the spring T, and the inclines
upon the stud & serves to throw the clutch from one pulley to the other according
to the direction in which the bar P is moved.
As represented in the drawings and as usually constructed the heads of the
spools are inclined outward, so that the layers gradually increase in extent from
the body of the spool outward. To adapt the machine for these gradually increasing
layers each of the two sides of the cam R2, presents a correspondingly inclined
surface, as seen in Figures 4 and 5, and these surfaces run between the two stops
P³, P, as seen in Figures 3 and 4. To the shaft R, on which the cain R' is fixed,
an intermittent rotation is imparted by means of a pawl S, working in a ratchet S,
on the shaft R, as seen in Figure 2; this pawl is pivotted to one end of a lever S³,
the other end of the said lever being fixed to a rock-shaft S³, to which a spring S',
(Figure 3) is applied, the tendency of which spring is to draw the pawl rearward,

page_text: and hold it in the position seen in Figure 2. From the rock-shaft an arm S³,
extends to the rear, where it is provided with a cross piece So, which stands in the
path of a projection S7, extending up from the nut (see Figures 1 and 3) so that as
the nut travels in one direction, an incline upon the upper side of the projection S',
passes beneath the cross-piece S, raising that cross-piece, and through its connec-
tion with the shaft S³, turns that shaft so as to impart to the pawl S, an advance
movement, to the position indicated in broken lines in Figure 2; this advance of
the pawl correspondingly turns the ratchet S', and the shaft R, and with it the
cam R'; starting therefore with the stops P3, P³, adjusted so that the broader or more
projecting parts of the cam will strike the stops respectively at each end when the
thread-guide has traversed the length of the barrel of the spool, and thereby move
the shifting bar P³, to throw the clutch from one pulley to the other as the work
continues, the cam will be turned, bringing narrower or less projecting parts into
line with the stops P3, P4, so that the shifting of the bar will occur later and so on
until the spool is completely filled. The pitch of the cam R', usually corresponds to
the incline of the two heads of the spool. The turning of the cam is produced only
at one extreme, and this is all that is practically required, yet it may be done at
both ends by causing the projection S³, to operate upon the rock-shaft at both
extremes of its movement.
The number of teeth on the ratchet should correspond to half the number of
layers of thread, so that when the spool is completely filled, or the required
quantity is wound thereon, the eam will have made a complete revolution, and come
into position to begin the winding of the next spool. If however the turning of
the cam be made at both extremes, then the number of teeth on the ratchet should
correspond to the number of layers of thread.
When the required quantity of thread has been wound upon the spool, a projec-
tion or shoulder r, on the cam, (see Figure 6,) will strike an arm, which projects
from the latch 7, and depress that latch, as seen in broken lines in Figure 3. The
shipper lever W, (see Figure 1), is caught by the shoulder, in the usual manner,
A spring holds the latch up, and permits it to yield for the shipper lever to be
thrown into engagement with it. As soon as the requisite number of layers has
been wound upon the spool, the shipper lever is released to disengage the power
which drives the machine, then the spool is removed, another introduced, the power
again applied, and so the work goes on.
It will be understool that the shipper-lever W is similar to an ordinary shipper
lever by which a driving belt is shifted from a fast on to a loose pulley, or vice
versa the broken lines indicating the position of the said lever when the belt is
on the loose pulley.
If at any time it is desired to stop the machine, the latch is disengaged from the
shipper lever by depressing it either directly, or through a hand-lever 7 (-ce
Figure 2,) which is connected to the latch 2, by a rock-shaft.
The arrangement of the two pulleys F. F, to be driven in opposite directions by
the same band which drives the mandrel, is applicable to machines employed for
other purposes where a similar reverse movement is desirable, I therefore do not
limit this part of the said invention to the spooling machine.
It will be understood that parts of the machine are irade adjustable to adapt it
to different sizes or lengths of spools, or different quantities of thread.
If a great quantity of thread is to be wound upon the spool so that numerous
layers will be required, the ratchet S', should be made with fine teeth, and the
movement of the pawl which actuates it should be such as to turn it according to
the number of layers, so that a full revolution of the cam will be made in the
winding of the spool, and so that when one spool is completed the machine may be
in position to begin the winding of another.
In cases of spools in which the inuer sides of the head are at right angles to the
axis of the spool, so that each layer is of the same extent, the cam will be made
with its two faces in parallel planes, and will be arranged to rotate so as to bring

page_text: 7"
the projection or shoulder into engagement with the mechanism to operate the
shipper lever when the winding is completed.
While I prefer to arrange the two pulleys F, F, so as to be operated by the same
band which drives the mandrel, it will be understood that the two pulleys F, F',
may be driven each by an independent band to impart rotation in opposite directions
to the said two pulleys, and the mandrel driven by its own independent, belt, or
other well known mechanism may be applied to impart rotation. to. the leading-
screw in either direction
Instead of reversing the leading-screw, it may be made a double threaded screw,
that is to say with one thread to the right, and the other to the left, with a double
nut applied thereto in connection with the thread-guide so that at one end one
part of the nut will engage with one thread and travel to the opposite end where,
that part of the nut will be thrown out, and the other part thrown in to return.
the guide; this is a well known mechanical equivalent for the single threaded,
Fcrew arranged to have its direction of rotation reversed.

The finger may be attached directly to the nut which travels on the screw.
