1 JAMES HALLIWELL of Green Street, Manchester, in the County of Lancaster,
Mechanic, do hereby declare the nature of this Invention to be as follows:-
My Invention relates to the machinery employed in the filling of spools with thread
as is well understood. In the class of machines to which my invention relates the
thread guides or layers are traversed to and fro by means of screws the spools being
filled by a repitition of the to and fro traverses of the guides so that there is an even
number of layers of thread. I obtain an odd number when required by disengaging
the nuts at one end of the traverse so that the guides can be passed back without
laying the thread the filling of the spools commencing say at the right end of one
spool and then at the left end of the next spool. To disengage the nuts 1 employ
a separating lever which is acted upon by a spring when such lever is unlocked.
The said lever is supported by a locking slide which is acted upon at the end of
the last traverse and the lever is unlocked and then moves in opposite directions the
arms which carry the nuts. The shaper apparatus consists of two notched plates
which are mounted to turn upon an axis. Each plate is provided with a finger
which near the end of the traverse in one direction comes into contact with the
shaper and turns the plate until the notches coincide whereby an arm upon the
reversing shaft is permitted to move and the said shaft to turn. The turning of
the said shaft is effected by means of rocking inclines which can yield against the
action of springs. During the traverse an arm upon the reversing shaft pressing
upon one of the said inclines extends or compresses the spring until the two notches
coincide as aforesaid when the re-action of the spring will effect the reversing
movement. The shaft which actuates the screws is driven through a friction clutch
which is caused to engage against the pressure of a spring. When the clutch is
disengaged the re-action of the said spring forces a face or collar upon the said
Shaft into contact with a surface of leather or other material whereby the rotatory
movement of the shaft is at once arrested. I employ a separate tension apparatus
for each spool. A spring acts upon a finger which projects from the guide. The
tension of the said spring can be regulated by means of a screw and a second
adjustable screw furnishes means for increasing the rigidity of the spring to any
desired extent when the spool is nearly full in order that the last layer may be
wound hard. I employ a double set of back spindles so that whilst the spools upon
one set are being filled the filled spools upon the other set are removed and empty
spools substituted. The back spindle carrier is so constructed and mounted as that
by a rapid to and fro movement combined with a semi revolution the spool
changing is effected with great rapidity. The to and fro movement is effected by
means of a lever or by suitable equivalent means. The semi-revolution is effected
by means of a spring which is put in tension by the attendant. A catch locks the
spindle carrier to prevent revolution until the spools are free from the driven
spindles and a stop limits the revolving motion. The half turn of the back spindle
carrier passes the thread into holding catches. If preferred the back spindle carrier
might be provided with more than two sets of back spindles and make less than
balf a turn at each movement. I may employ my invention in connection with a
former invention for which Letters Patent bearing date the sixteenth day of August
n the year 1887 and numbered 11162 have been granted to me.
Dated this 1st day of October 1888.

1 JAMES. HALLIWELL of Green Street, Manchester, in the County of Lancaster,
Mechanic, 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 and accompanying drawings :-
My Invention relates to the machinery employed in the filling of spools with
thread as is well understood. In the class of machines to which my invention
relates the thread guides or layers are traversed to and fro by means of screws the
spools being filled by a repetition of the to and fro traverses of the guides so that
there is an even number of layers of thread. I obtain an odd number when
required by disengaging the nuts at one end of the traverse so that the guides can
be passed back without laying the thread the filling of the spools commencing say
at the right end of ore, spool' and then at the left end of the next spool. The
shaper apparatus consists of two notched plates which are mounted to turn upon
an axis the co-incidence of the notches permitting an arm upon the reversing shaft
to move and the said shaft to turn. The turning of the said shaft is effected by
means of rocking inclines which can yield against the action of springs. The shaft
which actuates the screws is driven through a friction clutch which is caused to
engage to start the machine. When the clutch is disengaged a brake is permitted
to act to prevent overrunning. 1 employ a separate tension apparatus for each
spool. I provide a double set of back spindles so that whilst the spools upon one
set are being filled the filled spools upon the other set are removed and empty
spools substituted. The back spindle carrier is so constructed and mounted as that
by a rapid to and fro movement combined with a semi-revolution the spool
changing is effected with great rapidity.
My Invention will be fully understood from the following description with
reference to the accompanying drawings. In the said drawings Fig. 1 represents
a side elevation and Fig. 2 a plan of a nearly complete machine constructed in
accordance with my invention both these Figs. being partly in section. The parts
omitted to the right hand in these Figs. correspond with the parts which appear
upon the left. Fig. 3 is an end view of the machine and Fig. 4 a vertical section
on, the line A in Fig. 1. In the said Figs. a. a are two revolving spindles which,
give motion to the spools whilst being filled each spindle driving two spools by
means of its two end driving heads a¹. The two spindles receive motion from the
driving pulley through a friction clutch 6'. When this clutch is in driving gear
the driving shaft 2 is actuated and gives motion through the gearing c to the
spool, spindles a and through the gearing d to the right and left-hand screws e. e.
The half nuts e e¹ which engage with these screws and are thrown alternately into
and out of gear give motion to levers e² which are fixed upon a rocking shaft e
as in a former Invention for which Letters Patent Number 11162 of the year 1887
have been granted to me. This shaft is also fitted to slide endwise in its bearings
so as, to throw one of the nuts e¹ into gear and the other nut out of gear. When
the shaft is in an intermediate position both nuts are out of gear.
I obtain an.
odd number of, layers of thread upon the spools by employing parts which lock.
the said shaft in such intermediate position after a certain even number of layers
have been put on so that the nuts can be moved back and the odd layer put on.
by starting from the same end of the spool as when putting on the last previous
layers. The said locking parts, are additionally illustrated in Figs. 5 and 6 in.
sheet 2. In, Figs. 1. 2. 3 and. 6 f is the shaft which is revolved intermittently at
the end of every other layer and imparts a sliding motion, to the bar g' which
carries the adjustable shaper g. Hinged by one end to the framing is a locking
lever h which during the ordinary working of the machine is kept-in the raised
position shown in Fig. 5 by means of a bar h¹ which is fitted to slide in its
supports. In the said bar is a slit * which receives the locking lever when the
said bar is slid endwise the said lever being thus permitted to fall into position to

page_text: lock the rocking shaft c³. The sliding movement of the said bar is effected by a
part which is fixed upon the cam wheel f¹ and which is suitably formed and
situated to push the bar at the required time that is to say at the end of the last
but one required layer. The rocking shaft being thus locked in its intermediate
5 position the rocking shaft can be turned in its bearings by means of a suitable
handle so as to move back the two nuts and also to slide back the two layer
spindles i. and a fresh layer can be commenced from the same end of the spool
as the last previous layer. It must be understood that the part which slides the
bar is preferably removable from the wheel f¹ so that when an odd layer is not
required the said bar is not acted upon and consequently the rocking shaft is not
locked. The said rocking shaft receives its sliding movement from a second rocking
shaft which rocks at the end of each layer such movement being controlled by
the shaper. The shaper apparatus appears in plan in Figs. 7 and 8 which show the
parts in two positions. Upon vertical spindles k. k which are carried by a frame &¹
which is fixed to the layer spindles are fixed discs k which are notched to permit
of the movement of the end of an arm j¹ which is carried by the shaft j. The said
discs are acted upon by means of spiral springs which tend to turn the discs into
positions which prevent the movement of the said arm. To each disc is fixed a
finger each finger coming into contact with one of the adjustable parts of the
shaper by reason of the spindles & moving with the layer spindles i. By the finger
thus coming into contact with the shaper as in Fig. 8 the connected disc is turned
upon its axes until the notch in the disc will pass the end of the arm which is
then permitted to make a movement and the shaft j rocks slightly thereby moving
the shaft e³ end wise by means of a connecting lever at 7. The rocking movement
of the shaft is effected by means of inclines . which alternately act upon a
second arm
upon the shaft j. These inclines are formed upon levers which are
mounted to turn upon fixed fulcra which are carried by a bracket which is
attached to the bed of the machine. Spiral springs act upon the said levers and
tend to turn them inward toward each other the action of the arm having the
contrary effect to move the upper end of one lever outwardly away from the other.
As either lever yields to the action of the arm 73 it exerts a pressure upon such
arm which tends to rock the shaft and this pressure is continued until by reason
of the turning of one of the discs the arm j¹ is free to move when the shaft ; will
be rocked within its fixed limits by the pressure of the lovers and the shaft e
will be slid in its bearings whereby the one nut will be engaged and the other be
disengaged the direction of movement of the layer spindles being thus reversed.
Comparing Figs. 7 and 8 the end of the arm j¹ is represented as being held in the
notch in the upper disc in Fig. 7. The movement of the layer spindles and as a
consequence of the discs in the indicated direction causes the lower finger by
bearing against the shaper plate m to turn the lower disc as seen in Fig. 8 until
the notch in the lower disc coincides with the notch in the upper disc when the
end of the arm will leave the notch in the upper disc by reason of the pressure
of the lever and enter the notch in the lower disc thereby rocking the shaft j in
the direction indicated in Fig. 4 and the direction of movement of the layer spindles
will be reversed. During the next traverse the finger upon the upper spindle will
bear upon the shaper plato m' whereby the upper disc will be turned until by
reason of the pressure of the lever upon the arm the end of the arm j¹ is
caused to leave the notch in the lower disc and enter the notch in the upper disc,
the shaft then turning in a direction contrary to the indication in Fig. 4. As
hereinbefore mentioned the parts are actuated through the clutch b'.
The sliding
part of this clutch is attached to the driving pulley band is slid upon the shaft
by acting upon the handle ³. At the back of the spur wheel e in Fig. 2 is a
brake-plate c which is hinged by one end to the framing and is faced with leather
or if preferred the leather might be upon the spur wheel. The said brake plate
s acted upon by a spring which tends to press the leather face against the spar
vheel so as to act as a brake upon the wheel when it is revolving. A rod 6 is
inged by one end to the starting and stopping handle 6' the other end of this rod

page_text: ⋅
The
passing through an opening in the free end of the brake plate. Upon the said
rod is an adjustable collar 6. When the handle is moved to start the machine this
collar presses upon the brake plate and thereby moves its friction facing out of
contact with the wheel c but on the contrary when the handle is moved to start
the machine the brake plate is allowed to be pressed against the said wheel so as
to arrest the movement of the same and thereby to check over-running of the spool
spindles. As hereinbefore mentioned I provide a separate tension apparatus for each
spool. Each thread guide or layer n is carried by an arm n' which is mounted
upon the layer spindle i. A pin o is fixed to a branch of the said arm and bears
against a spring o' which is supported by an adjustable screw o. By turning the
said screw in one direction or the other the pressure of the guide upon the thread
upon the spool can be increased or decreased. When the spool is nearly full the
spring comes into contact with a second adjustable screw o³ whereby the spring is
rendered more rigid and as a consequence offers a greater resistance to the further
rising of the thread guide so that the last layer of thread is wound hard.
back spindles p. p are carried by a revolvable spindle carrier q which is mounted
to turn upon an upright pillar 9'. The said spindle carrier is provided with two
sets of back spindles which are diametrically opposite to one another. Whilst one
set is in use the other set can be provided with empty spools. A semi-revolution
of the spindle carrier moves the empty spools into position to be filled and at the
same time brings the filled spools into position to be readily doffed. Within a
recess in the top of the spindle carrier is a coiled spring r which tends to revolve
the spindle carrier. This spring can be wound up to the required extent by the
attendant either during the filling of each set of spools or at longer intervals a
wheel or part 2 which is connected with the centre of the coil of spring and is
provided with a ratchet and catch to prevent return motion being acted upon by
the attendant. At the bottom of the spindle carrier is a ratchet or notched wheel.
which permits of only half a revolution of the spindle carrier at each movement.
The upright pillar q' is secured to a sliding carriages and the two sliding carriages
one at each end of the machine are connected by means of links with a hand
lever sin such a manner as that by moving the said lever in one direction the
two carriages slide outward and away from each other a return movement of the
lever bringing both carriages back again into their first positions. At each outward
movement the spring catch t which keeps the spindle carrier from revolving is
momentarily acted upon to release the spindle carrier which is then permitted to
make a semi-revolution the catch holding the spindle carrier until the filled spools
are free from the driver spindles and immediately re-engaging after the semi
revolution to prevent further rotation of the spindle carrier. It will thus be seen
that by a to and fro movement of the hand lever s¹ the four filled spools are turned
out and four empty spools are turned in to take their places the horizontal movements
of the spindle carriers having the effect of withdrawing the filled spools from the
front spindles and of pushing forward the empty spools on to the said spindles.
The same semi-revolution of the spindle carriers also passes the threads into thread
holding catches u. u which hold the ends of the threads so that the filling of the
empty spools can be at once commenced. I do not confine myself to the precise
details for rotating the spindle carriers nor to the number of sets of back spindles
with which each carrier is provided so long as the spindle carriers when being
moved horizontally are partly rotated so as to effect the changing of the spools
substantially as described.
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 :-
'-
(1) The locking lever sustained during the ordinary working of the machine
,but released when an odd layer is required and when released acting to keep both
nuts out of gear so that they can be quickly moved back substantially as and for
the purpose set forth and indicated.
