1, HENRY HARRIS LAKE of the firm of Haseltine Lake and Company, Patent
Agents, 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 :-
This invention has for its object to improve the construction and operation of that
class of spooling machines in which the length of the successive courses is determined
by the shape of the spool-heads, and it consists in the several improvements hereinafter
described.
In the accompanying drawings,

Figure 10 represents an end view of another modification.
Figures 11 and 12 represent respectively top and front views of the modification
shown in Figure 10.
Figures 13, 14, 15 and 16 represent views of another modification.
The same letters of reference indicate the same parts in all the figures.
a represents the supporting base, having suitable standards or bearings, bb, in
which is journalled the shaft or spindle c, on which the spool to be wound is placed,
and the feeding screws e e¹. The said screws are connected by gears fƒ, (Figure 2)
so that they are rotated in opposite directions. The screw e¹ is provided with a
spindle c,
differential pulley, g, which is belted to a differential pulley h, on the shaft or :
the screws e e¹ being thus rotated.

page_text: i represents a thread carrier, mounted to slide on a rod j, which is supported by the
standards kk, in which the screws e e¹ are journalled. The said carrier has a grooved
forward end which projects over the spool on the spindle c, and delivers the thread in
courses to said spool. In the central portion of the carrier is an opening through
which passes the rod j, on which the carrier slides. I represents a short arm mounted
on the rod within the opening in the thread carrier, said arm extends downwardly
between the screws e e¹ and is adapted both to oscillate on the rod j and to slide
thereon with the thread carrier. In the opposite sides of the arm are formed half-
nuts m m³, Figure 4 adapted to engage respectively with the screws e e¹. The arm l
has a play between said screws, and when moved to one extreme of its oscillating
movement one of its half-nuts is engaged with one screw, and when moved to the
other extreme its other half-nut is engaged with the other screw.
It will be seen
therefore that the thread carrier will be moved in one direction when the arm / is in
contact with one screw, and in the opposite direction when the said arm is in contact
with the other screw.
In machines of this class in which a thread carrier is reciprocated by the action of
oppositely rotating screws of like pitch, or of a right and left screw formed in one
upon nuts connected with the thread carrier, automatic devices are provided whereby the
movements of the carrier are reversed after each course of thread has been completed.
The spools upon which the thread is wound have end flanges which are tapered or
frusto-conical at their inner faces, so that each course has to be somewhat longer than
the preceding course, to fit the courses to the tapered heads. Heretofore the increase
in the length of the successive courses has been determined by devices entirely
independent of the spool-heads, the increase in the length of each course being
arbitrary, so that unless the spool-heads are formed in exact accordance with the
operation of the course lengthening devices the ends of the courses will be imper-
fectly formed. It has been necessary therefore to change or adjust the course
lengthening devices to accommodate them to spools of different form from that to
which they had previously been adjusted. Moreover such nicety of adjustment or
correspondence between the course lengthening devices and the taper of the spool
heads was required that it has been difficult to secure the desired uniformity and
perfection of winding.
The objections above referred to are provided for by providing automatic devices
which are acted on directly by the conical heads of the spools, so that the length of
each course is determined by, and fitted to, the inclination of the spool heads, and no
adjustment or adaptation is required to enable the machine to operate with spools
having differently formed heads. To this end automatic means are provided whereby
pressure is applied to the arm / having the half-nuts m m' during the latter part of
each movement of the carrier, such pressure tending to separate the arm from the
screw with which it is for the time being engaged, and force the said arm into
engagement with the other screw, a movable guide or abutment which supports the
arm against said pressure until the course of thread being wound has reached its
proper length, and mechanism whereby the position of said abutment is varied so that
it will release the arm and permit the pressure applied thereto to move it into
engagement with the other screw when each course is completed, a part of the said
mechanism being in contact with the spool, so that the action of the mechanism in
reversing the movement of the thread carrier is caused by the head of the spool.
Referring to Figures 1, 2, 3 and 4 of the drawings, n n' represent springs supported
by studs o o' on the base a, and arranged as shown in Figure 2. The said springs
bear alternately on the lower portion of the arm having the half-nuts, and each
spring when in action presses the said arm against a movable bar or abutment p, which
when in operative position projects upwardly through a slot in the base a and stands
parallel with the screws e e. The movement of the arm with the carrier is from the
fixed to the free end of the spring bearing against said arm, and the arm in moving
with the carrier does not come in contact with the spring until the carrier has made a
part of its movement. When the arm comes in contact with one of the springs it

page_text: gradually displaces the said spring as indicated in Figure 2, the springs normally
bearing at their free ends against stops q q' on the base a. When the course of
thread laid on the spool by one movement of the carrier has reached the proper length
the abutment p is depressed by mechanism next described, thus releasing the arm
and allowing the spring bearing against it to force said arm to the other side of the
space occupied by the abutment when the latter is raised, and thus engage the other
half-nut with the other screw, and reversing the movement of the carrier. During
the ensuing movement of the carrier the arm bears against the other spring, displacing
the latter so that when the abutment p is again depressed the arm 7 will be forced
by the spring last referred to back to the opposite side of the abutment, thus engaging
the arm with the first screw, and so on. The abutment p is raised as hereinafter
described after each depression, so as to guide the arm in each of its movements.
The mechanism for depressing the abutment p is as follows:
:-
represents a lever adapted to oscillate vertically in a slot in a bracket or standard t,
affixed to the base, and pivotally connected at one end to the abutment p, said lever
being below the base a.
s represents a spring which is suitably attached to the base, and supports the lever
and abutment p permitting said abutment to be depressed below the lower end of the
arm and raising said abutment when the same is not subjected to depressing
pressure.
u represents a stud adapted to slide vertically in a socket extending through the
base its lower end bearing on the lever r.
a,
ve represent bell-crank levers pivoted respectively at ww¹, to standards on the
base a each having a substantially horizontal and a substantially vertical arm. The
horizontal arms of said levers bear on the upper end of the stud u, and their vertical
arms are connected by a horizontal rod a¹ inserted in vertical slots b¹¹in said arms.
The rod a¹ passes through a sleeve c¹ affixed to the rear portion of the thread
carrier i, and is provided with a head d¹ (preferably adjustable) bearing against the
outer side of the vertical arm of the lever and with a nut f¹ (on a threaded portion
of said rod) bearing against the outer side of the vertical arm of the lever v'.
g' represents a double cam lever pivotted at h¹ to the sleeve c¹ its lower portion
being located in a slot in said sleeve, and adapted to bear upon the rod a¹ within said
sleeve, while its upper portion projects above the sleeve and is engaged by the forked
rear end of a lever i¹. Said lever extends along the thread carrier to its front end
and is pivotted at j' to the thread carrier so as to be capable of oscillating horizontally
thereon. The forward end of the lever is provided with two downwardly projecting
flanges or "feelers"¹² which stand at opposite sides of the thread guiding end of
the thread carrier, and project over the spool, their lower edges being slightly higher
than the lower edge of the portion of the thread carrier that bears on the thread
on the spool, so that the feelers will not be affected by contact with the thread.
The lower edges of the feelers are however in close proximity to the surface of the
thread on the spool and are arranged to strike the heads of the spool as hereinafter
described.
The operation as a whole is as follows:-
The arm being engaged with the screw e¹ as shewn in Figures 3 and 4 and the
screws being rotated in the directions indicated by the arrows in Figure 4 the
thread carrier will be moved in the direction indicated by the arrow in Figure 1,
and is thus caused to lay a course of thread upon the spool.
When the movement of the carrier in the direction indicated brings the flange or
feeler in contact with the head at the right hand end of the spool. The lever i¹ is
arrested by such contact, and is caused to swing on its pivot by the continued move-
ment of the carrier until its rear end, engaged as described with the cam lever gl
turns said lever on its pivot and causes one of its cam portions to bind upon the rod a',
as shewn in Figure 6, thus locking the rod a¹ to the carrier and causing the carrier
to move the rod with it. This movement of the rod a¹ causes the head on said rod
to displace the bell crank lever v, as shewn in Figure 6 until said lever depresses the

page_text: stud U,
lever and abutment p and thus causes the abutment to release the arm
whereupon the spring n¹ forces said arm to the opposite side of the abutment. dis-
engaging its half nut m¹ from the screw e¹ and engaging its half nut m with the
screw e, thus reversing the motion of the thread carrier. Whereupon the spring s
immediately raises the abutment o to its normal position, holding the half nut m in
connection with the screw e. When the ensuing movement of the carrier brings the
feeler in contact with the opposite head of the spool, the lever ¹ is again caused to
turn and engage the cam lever g¹ with the rod a', and said rod is moved by the
carrier so as to displace the bell crank lever v¹ and cause the latter to depress the
lever and abutment p, as before. The spring n then forces the arm over into
engagement with the screw e¹, and thus the movement of the carrier is again reversed.
The operation continues in the manner described until the spool is filled, each course
of thread being terminated by the action of the feelers on the heads of the
spool.
When the accumulation of thread on the spool is such that the inner surfaces of
the heads are nearly covered, so that the feelers cannot engage operatively with said
heads, the feelers are arrested by contact of the rod i¹ with screws 11 11, supported
by arms p¹ p¹, mounted on the rod j on which the carrier slides. Said arms are
connected by a rod 1 which bears upon the lever and supports the arms p¹ p¹ at the
proper height above the spool. The screws are adjustable in the arms p¹ pl so
that their inner ends can be set to correspond to the distance, between the heads of
the spool, and are provided with jam nuts, s¹ s¹, whereby they may be prevented from
moving or turning accidentally.
Springs t¹t, are interposed between the arms p¹ p¹ and the standards kk to enable
said arms and the screws ¹ therein to yield slightly while the thread carrier is
completing its movement after the rod a' has been locked to it.
A spring u¹, is placed between the base a and the inner ends of the horizontal
arms of the bell crank levers v v¹ to restore said levers to their normal positions
after they have been displaced in the manner described. A spring a² attached to the
rear end of the lever and projecting between pins, 62 62, on the rear end of the
carrier, normally holds said lever with its feelers at equal distances from the thread
guiding end of the carrier, as shewn in Figure 1 and permits the described swinging
movements of the lever and its feelers from the position indicated.
The lever is preferably made in two parts or sections, 2, 3, pivotally connected
at 4. The section 2 has a slot through which passes a thumb-screw 5, which is
screwed into the section 3 and when turned to place rigidly connects the two sections
so that neither can turn on the pivot 4. The object of this construction is to permit
the adjustment of the feelers to make them normally exactly equidistant from the
thread guiding end of the carrier; said adjustment being effected by loosening the
screw 5, turning the sections 2, 3 on the pivot until the feelers are equidistant from
the carrier, and then tightening the screw 5.
To ensure a sufficient downward pressure of the thread carrier and on the feelers,
and prevent the feelers from sliding on the inclined surfaces of the spool heads, I
provide a weighted lever, c², which is pivotted at e² to a standard f2, and bears at one
end against a lateral bar g2 affixed to or formed on the rear end of the thread
carrier ; said lever having an adjustable weight, d2 whereby it is caused to press
upwardly against the rear end of the thread carrier, and thus exert a downward
pressure on its forward end, the thread carrier being capable of oscillating or turning
on the rod j, as already explained. A spring or any equivalent pressure device may
be used instead of the weighted lever for the purpose specified.
The spools are removed from the spindle c by means of a slide 12 fitted to slide
in guides m² m² in the base a, and provided with a vertical arm n², which has an
orifice through which the spindle c passes. Said slide has a rack, o2 with which
meshes a segment, p² pivotted to the base a and provided with a handle q². By
moving the said handle the arm n² may be forced against one end of the spool so as
to force the latter off from the spindle, as will be readily seen.

page_text: I prefer to pivot to the slide, a platen, which is bent upwardly to form a
vertical arm n³. Said arm n is normally pressed by a springs, away from the
slide 2, as shown in Figures 1 and 1ª, but is adapted to be moved over the said
slide so as to bear against the outer end of a spool placed on the spindle c. The
function of the arm n³ is to bear against the outer end of an empty spool, and press
the latter to place on the spindle when the slide 12 is being moved back after the.
filled spool has been doffed. After the empty spool is placed on the spindle and
before the slide 12 is moved to its spool holding position the operator turns the arm n
over the slide 2 and then by a reverse motion of the lever q forces the slide back to
its operative position.
It is obvious that by this device I am enabled to crowd every spool of a given length
to a fixed position on the spindle, which is a decided advantage in machines of this
class.
A slot, in the plate n allows the arm n³ to be adjusted for spools of different
lengths.
A modification is shown in Figures 7, 8 and 9 in which the abutment p is made
in two overlapping parts, 7 8, each capable of sliding so as to shorten and lengthen
the abutment. In this case the abutment is not moved vertically, but is lengthened
at the completion of each course of thread by two crossed levers a, a, pivoted at 6*
to a fixed support and pivoted at their rear ends to arms, p* p*, formed on the parts 78
of the abutment. A spring d forces the ends of the levers apart. The forward
ends of the levers bear upon the under side of the spool and are kept by the
spring d in constant contact with the inclined surfaces of the spool-heads. It will
be seen that every course of thread added to the spool forces the levers a a¹ farther
from the centre of the spool and allows their ends to be opened more widely, so that
the abutment is gradually lengthened by the accumulations of thread on the spool the
arm is moved beyond the ends of the abutment p by each movement of the thread
carrier, and is forced across the abutment by one of the springs after passing each
end of the abutment.
It is obvious that instead of employing two screw rods rotating in opposite directions
as the means for reciprocating the thread carrier, a single rod may be employed having
a right hand threaded portion 9, and a left hand thread portion 10, as shown in
Figures 11 and 12. In this case the rod j on which the thread carrier is adapted to
oscillate should reciprocate with the thread carrier and have two arms ff each
having a half nut, one of said arms being arranged to engage with one side of the
right hand thread of the screw rod, and the other arm with the opposite side of the
left hand thread. The arm which is pressed by the springs against the abutment p
will in this modification be attached to the rod j.
In Figure 1b I have shown the lever i provided at its rear end with a section 2¹
which is adapted to slide cross wise of the lever ¹ in guides formed in the latter and
is adjustably secured to the lever i¹ by a screw so which serves to move the section 2¹
and hold it in any desired position so as to adjust the cam lever holding slot in
said section with reference to the lever i¹. A spring 10 attached at one end to
the carrier and at the other end to the section 2¹ performs the same function as
the spring a².
In Figures 13, 14, 15 and 16 a simplified machine is shown in which both screw
threads are formed on a single shaft, as in Figures 11 and 12, and the abutment is
arranged to oscillate and is interlocked with the arm of the sliding shaft j.
Referring to the figures last named, 9, 10 represent the right and left hand screw
threads formed on a single shaft, as in Figures 11 and 12. represents the sliding
shaft having the arm and the half nuts f f adapted to engage with the screw
threads 9, 10, one half nut being on one side of the shaft on which the said threads
are formed and adapted to engage the right hand thread, while the other half nut is
at the opposite side of the shaft and adapted to engage the left hand thread.
c represents the shaft or spindle on which the spool is placed the said spindle being
rotated by any suitable means. i represents the thread carrier mounted on the sliding

page_text: snait and adapted to guide the thread to the spool, and also to turn or oscillate on
the sliding shaft j.
The direction of movement of the thread carrier is changed in this type of machine
by a change lever A, separate from the thread carrier and located at the under side of
the spool. Said change lever is connected by a pivot B to a carrier C, which is
adapted to slide on a stud D affixed to the frame of the machine. The change lever is
made in two parts 2, 3; the part 2 being pivoted at B to the part 3, while the part 3
is connected by the pivot B with the carrier C and is engaged with the part
screws F passing through ears on the part 2 and bearing against the edges of the
part 3 this construction being for the purpose of adjusting the end of the change
lever that is acted on by the spool heads.
by
The carrier C supports and is adapted to slide on a rod a¹ which corresponds in
function to the rod a¹ shown in Figures 1, 5, 6, &c. A double pawl g' (corresponding
to the cam g' shown in Figures 5 and 6) is pivoted to the carrier Cand is engaged
by the rear end 3 of the change lever, so that upon the contact of said lever with
either of the spool heads the swinging motion of the change lever, caused by such
contact, will cause the pawl to engage the surface of the rod a¹ which is serrated or
milled for this purpose, and give an endwise motion to said rod. Two arms H H are
affixed to the rod a¹ and between said arms are the upper ends of two levers I, I, which
are pivoted to a standard J affixed to the frame of the machine. The lower ends of
the said levers are drawn towards each other by a spring K attached to the levers
below their fulcrums or pivots, the upper ends of the levers being thus held with a
yielding pressure against the arms H, H. of rod a', while their lower ends are pressed
against a latch lever L affixed to a rock shaft M. Said rockshaft is mounted to rock
on fixed bearings N N and has a frame or abutment p affixed to it, which frame is
engaged with a slot O formed in the lower end of the lever 1, so that said lever is
engaged with the abutment p in any position it (the lever) may assume.
The springs n' n', are employed as in the previously described constructions, to bear
against opposite sides of the arm and act alternately thereon, as already set forth.
The thread guide or carrier and the change lever carrier are connected by gear
segments R R attached respectively to said thread guide and lever carrier, so that as
the thread fills the spool and forces the thread carrier gradually out from the
spool the change lever and its carrier will be forced out from the spool in the
opposite direction.
The gear segment on the thread carrier has flanges S S which project over
upon the sides of the segment on the change lever carrier, the two segments
being thus interlocked, so that the change lever carrier will move in unison with
the thread carrier. In the operation of this form of machine, when the change
lever strikes either of the heads of the spool and is turned on its pivot, it engages
the pawl g with the rod a¹ and causes said rod to move with the thread carrier
and change lever sufficiently to cause one of its arms H to displace the lever I
against which it bears, thus causing said lever to release the latch lever L with
which it was engaged, thus releasing the abutment p, whereupon the spring n or n¹
which is at the time displaced by the arm l, acts to force the said arm over and
bring the other half nut 4 into engagement with its screw, thus reversing the
movement of the thread carrier. The latch lever L is engaged by the other lever I
when the position of the abutment is shifted, and is thus held against the pressure
of the spring n¹ or n, which was displaced by the last movement of the rod j and
its arm l.
When the change lever strikes the other spool head the rod a¹ is again locked to
and moved by the change lever carrier, and its other arm H is caused to move
the lever I then engaged with the latch lever L, and again release the abutment
and permit the other spring n or n¹ to act on the arm and turn the shaft J to
bring the other half nut f₁ into engagement with its screw. The operation is thus
continued until the spool is filled. The change lever carrier has an arm c² on which
is an adjustable counterbalancing weight d².
