We JOHN HOLROYD, HARRY LIEBERT and CHARLES MGOWAN trading as
John Holroyd and Company Limited of Tomlinson Street, Hulme, Manchester, in
the County of Lancaster, Engineers and Machinists, do hereby declare the naturo
of this Invention to be as follows:-
Our said Invention relates to apparatus employed in winding or spooling yarn or
thread upon bobbins, spools or reels as is well understood, and refers more particularly
to single spooling heads. The improvements consist of several novel features in detail
and arrangement of parts which ronder such spooling heads more useful and effective
than heretofore. The bobbin or spool is mounted as usual upon the end of the driving
shaft or of a suitable revolving spindle and receives the yarn through a guide of tho
usual form. The guide is carried by a weighted frame mounted on the end of a
spindle sliding in the head and carrying half nuts by means of which it is slid to and
fro through the agency of a revolving spindle formed with a right and left hand
screw in the ordinary manner. At the spooling end of the head is a ratchet wheel
which is moved intermittently round by a pawl or pawls actuated by rocking levers
from a double slide or box which is connected by stays to the sliding spindle beneath
and partakes of its reciprocatory motion. The said double slide is composed of two
parts, which slide together through a portion of the stroke until the upper part of the
slide is arrested, when the lower part completes the stroke alone. This independent
action of the double slide is necessary to bring into action the spring mechanism in
the slide whereby the half nuts on the sliding spindle are brought into contact
alternately with the right and left hand screws on the revolving spindle. The upper
half of the slide has two spring bolts in line with each other and with a space
between their inclined ends or noses. A tongue connected with the sliding spindle
and pulled to one side or the other by a spring, lies in contact with the side of one of

the upper half of the slide is arrested, the tongue, still partaking of the motion of the
spindle, slides along the side of the bolt until it comes opposite to the opening
between the bolts, when it shoots through the said opening, turning the sliding
spindle on its axis, so as to remove one of the half nuts from one side of the
screw spindle and apply the other half nut on the opposite side whereby the motion
of the spindle and slide is reversed. The arresting of the upper portion of the slide
and the consequent governing of the motion of the lower portion is brought about by
the employment of a double stop carried on the upper part of the slide. The acting

page_text: .
faces of the said stops are made adjustable so that in shape and angle they can be
made to correspond exactly to the angle or shape of the ends of the bobbin or spool
and this setting of the stop can be done from the bobbin or spool itself. The double
stop moves to and fro with the slide and a plate is situated between the adjusted ends.
When one of the ends strikes against the plate the upper half of the slide is stopped
and the reversing operation hereinbefore described takes place. As the spool becomes
filled with thread, the plate is correspondingly raised so that the height of the plate
relatively to the adjusted stop is the same as the level of the last layer of wound on
yarn relatively to the sides of the bobbin. The plate thus governs exactly the length
of each layer of yarn wound on. The plate is gradually raised as the spooling pro-
ceeds, the raising being effected by a cam which is fixed to and revolves with the stud
which carries the aforesaid ratchet wheel at the spooling end of the head and which is
intermittently rotated by a pawl or by pawls as aforesaid. A spring holds the plate
down against the periphery of the cam. The ratchet wheel which gives motion to
the cam is actuated from the upper portion of the double slide by means of a horizontal
lever having a cranked slot in which a peg from the slide moves to and fro so as to
rock the lever and actuate the pawl or pawl's moving the ratchet wheel. At each
stroke of the slide the ratchet wheel is advanced say one tooth, or it might be more or
less than one tooth, the cam being at the same time correspondingly turned. The cam
not only raises the stop plate but also elevates a lifter whereby a flat pivotted plate
situated beside the weighted frame is raised. A screwed stud projects from the
weighted frame and carries an antifriction bowl which can be adjusted by means of
nuts on the stud at any desired distance from the pivot of the plate. The effect of
this arrangement is that the weighted frame can be raised more or less quickly
according to the position of the bowl on the plate, this adjustment being effected with
reference to the fineness or coarseness of the yarn or thread, so that the yarn guide
on the weighted frame is gradually raised to an extent exactly corresponding to the
thickness of the successive layers of thread so that a constant- and unvarying
pressure of the guide on the thread is obtained. On its way to the guide the
yarn is led under a finger which rests upon it. This finger projects from a bell
crank lever, one of the members of which is formed to engage with a ratchet
wheel which is rotated by a worm and wheel from the revolving right and left
screw spindle. So long as the yarn remains unbroken the finger is sustained and
the lever is kept from engaging with the ratchet wheel, but when the yarn breaks
the finger drops and the lever engages with the ratchet wheel. This has the effect of
releasing a spring rod carrying the belt fork and a brake, so that the belt is shifted
from the fast to the loose pulley of the driving shaft and the brake applied so as
immediately to stop the machine. We also arrange for the automatic stopping of the
machine when the spool is filled. The aforesaid ratchet wheel is provided with an
adjustable stop, which when the spool is full, comes in contact with the stopping
mechanism so as to shift the belt fork and apply the brake as in the former instance,
at the same time the paw! or pawls is or are lifted out of gear with the ratchet wheel
whereupon a volute or other suitable spring at the back of the ratchet wheel
returns it to the starting point. The finished spool is removed or doffed from the
end of the spindle by a sliding rod and doffing lever. Previous to the doffing
operation the guide is raised from the spool by lifting the weighted lever and hooking
it to the end of the plate or to any other convenient part or catch. The cam being on
the same axis as the ratchet wheel is caused to turn therewith by the action of the
spring so that the building stop plate and the guide presser plate are simultaneously
returned to their starting points the apparatus being thus ready for receiving and
filling a fresh spool.

Improvements in Automatic Yarn and Thread Spooling Machinery.
We JOHN HOLROYD, HARRY LIEBERT and CHARLES MCGOWAN trading as John
Holroyd and Company Limited of Tomlinson Street, Hulme, Manchester, in the
County of Lancaster, Engineers and Machinists, 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
Our said Invention relates to apparatus employed in winding or spooling yarn or
thread upon bobbins, spools or reels as is well understood and refers more particularly
to single spooling heads. The improvements consist of several novel features in detail
and arrangement of parts which render such spooling heads more useful and effective
than heretofore.
And in order that our said invention may be properly understood we will now
proceed more particularly to describe and ascertain the same reference being had to
the annexed sheet of drawings and to the letters and figures marked thereon, to be as
follows, that is to say-
Fig. 1 is a view at the spooling end of the apparatus.
Fig. 2 is a side elevation at the side marked a Fig. 1.
Fig. 3 is a plan view.
Fig. 4 is a sectional view at the line A. B. Fig. 1.
The bobbin or spool a is mounted as usual upon the end of the driving shaft bor of
a suitable revolving spindle and receives the yarn e through a guide d of the usual
form. The guide d is carried by a weighted frame e mounted on the end of a spindle
sliding in the head c and carrying half nuts or screwed bowls g by means of which it
is slid to and fro through the agency of a revolving spindle & formed with a right.
and left hand screw in the ordinary manner. At the spooling end of the head is a
ratchet wheel i which is moved intermittently round by a pawl or pawls j actuated by
a double rocking lever a spindle & having a twist end sliding in and actuated from a
projection from a double slide or box m, m³ which is connected by stays n to the
sliding spindle beneath and partakes of its reciprocatory motion. The said double
slide is composed of two parts m. m' which slide together and at the same speed
through a portion of the stroke until the upper part m of the slide is arrested, when
the lower part m completes the stroke alone. This independent movement of the
double slide is necessary to bring into action the spring mechanism whereby the nuts g
on the sliding spindle are brought into contact, alternately with the right and left hand
screws on the revolving spindle h. The upper half m of the slide has two spring
bolts o in line with each other and with a space between their inclined ends or noses
as seen at Fig. 3. A tongue p carried by an upright p¹ from the loose sleeve p² on
the sliding spindle is pushed to one side or the other by springs which act on the
bottoms of the projections carrying the nuts g. When the upper half m of the slide
is arrested, the tongue p still partaking of the motion of the spindle / slides along the
り

page_text: When one
The
side of the bolt o until it comes opposite to the opening between the bolts, when it is
shot through the said opening by the action of one or other of the springs 9 turning
the sliding spindle on its axis, so as to remove one of the nuts g from one side of the
screw spindle and apply the other nut on the opposite side whereby the motion of the
spindle and slide m. m² is reversed. The arresting of the upper portion m of
the slide and the consequent governing of the motion of the lower portion is brought
about by the employment of inclined building plates ». » carried on a spindle s from
the upper part m of the slide.. The acting faces of the said plates are made adjustable
so that in shape and angle they can be made to correspond exactly to the angle or
shape of the ends of the bobbin or spool a and this setting of the plates can be done
from the bobbin or spool itself. The building arrangement r. r moves to and fro
with the slide m. m² and a plate t is situated between the adjusted ends.
of the ends strikes against the plate the upper half of the slide is stopped and the
reversing operation hereinbefore described takes place. As the spool a becomes filled
with thread, the plate is correspondingly raised so that the height of the plate
relatively to the adjusted inclined building plates is the same as the level of the
last layer of wound-on yarn e relatively to the inclined sides of the bobbin a.
plate thus governs exactly the horizontal length of each layer of yarn wound on.
The plate is gradually raised as the spooling proceeds, the raising being effected by a
cam (see Fig. 4) which is fixed to and revolves with the stud which carries the
aforesaid ratchet wheel i at the spooling end of the head and which is intermittently
rotated by a pawl or by pawls j as aforesaid. A spring holds the plate down against
the periphery of the cam as clearly shown at Fig. 4. A cach stroke of the slide m. m¹
the ratchet wheel i is advanced say one tooth, or it might be more or less than one
tooth, the cam being at the same time correspondingly turned. The cam not only
raises the stop plate but also acts on a lever w so as to move it outwards as the cam
revolves in the direction of the arrow Fig. 4. The lever w is connected to a flat plate
or platform a pivotted at y on the side of the head c. A screwed stud z projects from
the weighted frame e and carries an antifriction bowl 1. which can be adjusted by
means of nuts on the stud z at any desired distance from the pivot y of the plate.
The effect of this arrangement is that the frame e can be raised moro or less, quickly
according to the position of the bowl 1 on the plate this adjustment being effected
with reference to the fineness or coarseness of the yarn or thread c so that the yarn
guide d on the frame e is gradually raised to an extent exactly corresponding to the
thickness of the successive layers of thread so that a constant and unvarying position
or pressure of the guide on the thread is obtained. On its way to the guide d the
yarn is led under a finger 2 which rests upon it. This finger projects from a bell
crank lever 3 one of the members of which is formed to engage with a ratchet wheel 4
which is rotated by a worm and wheel h¹ from the revolving right and left screw
spindle h. So long as the yarn c remains unbroken the finger 2 is sustained and the
lever 3 is kept from engaging with the ratchet wheel 4 but when the yarn breaks, the
finger 2 drops and the lever 3 engages with the ratchet wheel 4. This has the effect
of pulling the lever 3 toward the centre of the ratchet wheel and in the direction of
the arrow Fig. 2. The bar 5 upon which the lever 3 is pivotted is also moved in the
direction of the arrow and its inclined end raises the bar 6 and knocks off the catch 7
from the stop 8. The catch 7 is carried by a lever 9 on the end of a spindle 10 (see
Fig. 3) and a spring on this spindle tends constantly to force it in the direction of
the arrow so that when the catch is released the spindle 10 immediately shoots in this
direction. As the spindle 10 carries a belt fork 11 the driving belt is immediately
shifted from the fast pulley 12 to the loose pulley 13 the brake 14 is applied and the
machine is stopped. This stoppage of the apparatus takes place when the yarn breaks.
We also arrange for the automatic stopping of the machine when the spool is filled.
The aforesaid ratchet wheel is provided with an adjustable stop which when the
spool a is full, comes in contact with a projection from a lever 15 sliding on the end
of the head c. By raising this lever a projecting peg 16 lifts the two pawls j clear of
the ratchet wheel which is immediately returned to its starting point by means of a
volute spring at the back of the wheel. At the same time a projection 17 on the

page_text: lever 15 raises the nose of a catch 18 on the end of the aforesaid spindle 10 and thus
lifts the catch 7 from the stop 8 (see Fig. 3) releasing the spindle 10 so as to shift the
belt fork, apply the brake, and stop the machine as in the former instance. The
finished spool is removed or doffed from the end of the spindle by the ordinary or by
a suitable sliding rod and doffing lever not shown in the drawings. Previous to the
doffing operation the guide d is raised from the spool a by lifting the frame e and
hooking it to the end of the plate or to any other convenient part or catch. The
cam being on the same axis as the ratchet wheel is caused to turn therewith by the
action of the volute spring so that the building stop plate t and the guide presser
plate are simultaneously returned to their starting points the apparatus being thus
ready for receiving and filling a fresh spool.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
(1.) The general arrangement and combination of apparatus for winding or spooling
yarn or thread upon spools or bobbins substantially as hereinbefore described and
shown.
(2.) In apparatus for winding or spooling yarn or thread upon spools or bobbins,
the double slide arrangement with spring bolts and sliding finger governed by springs
in combination with the adjustable inclined building plates and stop plate which is
raised as the spooling proceeds so as to reverse the stroke of the guide carrying frame
at the proper time and in accordance with the inclination of the sides of the bobbin or
spool substantially as described and shown.
(3.) The method of imparting motion to the ratchet wheel for actuating the cam
for raising the building stop plate and the guide lifting platform substantially as
described and shown.
(4.) The means for automatically stopping the apparatus when the spool or bobbin
is full of yarn or thread substantially as described and shown.
(5.) The means for automatically stopping the apparatus when the yarn or thread
accidentally breaks substantially as hereinbefore described and shown.
